The Desert God of Death in Douluo

Qian Renxue rubbed her sore eyes. She could not have imagined that a simple calculation technique could be expanded to such a profound level in Zeng Yixin's hands. At the beginning, she still had She didn't agree with it for a while, but after she spent a little time reading the four arithmetic operations part, the algebraic geometry that followed began to exceed the calculation range a little bit.

Is this really a trick?

Qian Renxue's slightly bloodshot pupils revealed a confused look.

Finally, when Qian Renxue had read the entire elementary mathematics book and was about to pick up advanced mathematics to tackle key problems, Dugu Bo came over with great kindness and took out a set of papers from the drawer.

"Have you finished reading? After reading, do the test paper. Don't think about taking advanced mathematics if it is less than [-] points. You won't understand it even after reading it. Of course, if you have higher requirements for yourself, it is okay to raise your score. Yes, and the eunuchs in your palace have urged you many times. I hope you will eat something first and then pay attention to rest. I have brought the message to you."

Dugubo placed a thick stack of papers on Qian Renxue's desk and left. This set of papers was also produced by Zeng Yixin. In order to ensure that the researcher did not read the book through it once and feel that he understood it, he was very considerate. A set of papers was produced for each subject to ensure as much as possible that the researchers in the college laboratory did not understand the existence of a certain formula, but mastered the specific usage of each formula.

Imperial examination?

Qian Renxue's heart tightened secretly. It seemed that Zeng Yixin's plan was bigger than she imagined. Selecting talents through imperial examinations was something that the ruling group generally considered. Qian Renxue couldn't help but think too much about the story behind Zeng Yixin. motivation.

But Qian Renxue is still very confident in the set of papers in front of her. They are just a few formulas. If she can understand them, she will naturally know how to use them.

...

two hours later.

Qian Renxue trembled at the answers and graded her paper. Each red x was like a knife cutting into her heart.

After finishing the multiple-choice and fill-in-the-blank questions, Qian Renxue's hand holding the pen was trembling. She didn't know why she could read the textbook so clearly, and why she turned into a Muggle when she started to answer the questions.

Qian Renxue guiltily completed all the steps for her big question, and when she finally calculated her results, she almost blacked out.

The final score for the 150-point paper was 75, exactly half of it.

At this time, Zeng Yixin, who was far away on the other side of the continent, naturally didn't know that Qian Renxue had put down his studies on government affairs and mathematics. At this time, he was at the back of the military formation watching the army attack the city.

Countless five-meter-tall undead giants stood on top of the city, throwing boulders at the siege team below. Many small, slender undead were shooting at the siege team below with bone spurs from their slender arms like sharp swords. Team.

Many teams carrying giant siege soul guides suffered heavy casualties before they even reached the city gate. Although they had already arrived at the foot of the royal city, the huge iron gate that had been replaced with metal at some point stopped the army like a chasm. Before.

No way!

Even the Frost Bone Dragon was pierced by a giant crossbow shot from nowhere when it tried to rush up to the city wall, and its wings were almost torn to pieces. In the end, it was thrown away under the control of the Yellow-toed Commander. He moved his two strong thighs and ran back in embarrassment.

Countless skulls burning with black flames were thrown at the army regardless of day or night, as if they were drugged, making all the soul saints present busy running for their lives and miserable.

They were clearly on the attacking side, but they were beaten as if they were on the defensive side. The skeleton army stationed in the royal city opposite was clearly on the defending side, but in terms of momentum, attack scale and attack frequency, they were more like the attacking side.

During this month-long tug-of-war, King Xiji finally succeeded in turning Anguo into a country of the dead. Countless armies of skeletons wearing a layer of cloth came towards them like a tidal wave.

After all, they were still a step too late and failed to enter the royal city as quickly as possible. At this time, they could only engage in this cruel tug-of-war.

Even the incendiary bombs that were so brilliant on Chiba City encountered Waterloo. Countless incendiary bombs roared into the sky and hit the royal city heavily, but the next moment they all hit the shield firmly, raging. combustion.

There is no way to eliminate the undead army on a large scale, but at this time, the coalition forces still have to bite the bullet and start the project. One can imagine the difficulty of this battle.

The entire battlefield was filled with the smell of gunpowder smoke and blood. After each siege, the aftermath troops would even reluctantly burn the soldiers on the front lines who might not be dead to ensure that the corpses on the front lines would not be inexplicably transformed into undead a few hours later. Legion, suddenly got up in the next war and gave everyone a painful blow.

This was a bloody lesson. From then on, even if some soldiers were injured and could not withdraw immediately, incendiary bombs must be launched as soon as possible after the siege team completed a round of attack.

The entire royal city is like a huge meat grinder, crushing the lives of all living creatures and undead.

"Yixin, looking at the posture of the coalition forces, it seems that they can't break this hard nut."

Gu Rong touched his beard and looked a little solemn.

Even if such a copper-iron wall were placed in Douluo Continent, there might not necessarily be people who would dare to pat their chests and say that they would be able to chew it down.

Let’s not mention the mysterious number zero, millions of undead, what is this concept?

Even if the Wuhun Palace establishes a state and calls itself the Wuhun Empire, its total number of soldiers and horses is only one million, and the number of soul masters is as high as nearly [-]. But just looking at the strength on paper, it is just on par with the steel fortress in front of you. That’s all.

This is because the other party has only taken over one kingdom of Anguo. If the entire Sun Moon Continent falls into the hands of the other party, then this place will completely become the underworld on earth, and tens of millions of undead will breed God knows how many terrifying undead warriors.

"normal."

Zeng Yixin nodded. It would be abnormal if a top necromancer could have his lair breached so easily. Many of the spells he mastered could not be used at all, and the same was naturally true for the other party.

But spells not only have depth, but also breadth. There are many kinds of spells that can be expanded horizontally. Just the thin layer of soft film placed on the city wall by the opponent. If there is no corresponding solution, it will be impossible to penetrate. .

If Zeng Yixin remembers correctly, this soft-membrane defensive formation was developed to prevent giant trebuchets from throwing gold juice. It had no practical defensive capabilities. Any powerful attack would instantly crush the opponent. If the protection is shot into the city, only the golden juice wrapped in a thin container will explode when it touches the soft film.

The so-called golden juice is actually human excrement collected together. Generally, only the defenders of the city will use this kind of thing. After heating it in a large pot and pouring it from the city wall, it can not only cause severe burns and psychological damage, but also It will greatly increase the risk of infection to the attackers, which is not to say that it is not cruel.

Of course, in war, there is no such thing as being vicious or not. Anyone who can catch mice is a good cat, and anyone who can pull out pus is a good ointment. But I don’t know which unscrupulous guy came up with a way to attack the city. A bad idea to collect the golden juice and project it towards the city wall.

Zeng Yixin guessed that the person who came up with this idea at that time might have been disgusted by the golden juice on the city guard, and wanted to treat others in their own way. Not to mention, although this golden juice was not enough However, when the gold juice bomb roared from the sky and exploded accurately on the city wall, the morale of the entire army was greatly boosted.

Later, a warlock came up with this kind of magic circle that was not considered a defensive magic circle. Although it was no better than a traditional magic circle and could withstand all physical and energy attacks before the energy was exhausted, it was cheap to make and consumed little. It also brought the form of warfare back to a strategic position where only city defenders were eligible to use gold juice.

But even Zeng Yixin never expected that in the hands of the King of the West, this inferior magic circle would transform into the best defense against incendiary bombs that could explode at the first touch.

Coupled with the fact that the undead soldiers guarding the city on the city wall were all covered in heavy frost, one can imagine how difficult it was for the coalition forces to fight this battle.

Zeng Yixin said with some seriousness: "It seems that we have to find a way to help these coalition forces, otherwise we will maintain this situation. Under the ebb and flow of the situation, let alone the subsequent siege, we will even retreat unscathed and deal with them." It’s also a big trouble.”

Gu Rong perked up when he heard this: "Do you need me to take action?"

Seeing Gu Rong who was eager to try, Zeng Yixin ruthlessly dampened Gu Rong's enthusiasm.

"Don't worry, Dugubo and Lou Gao successfully converted chlorine trifluoride for military use some time ago. Although this thing is very dangerous, there is no problem at all if you burn through the opponent's protective shield first and then have a big barbecue for the entire royal city. Yes, it’s a pity that the reserves of this thing are pitifully small. The laboratory only produced a total of thirty tons, and only about ten tons were allocated to me.”

Hearing this, Gu Rong frowned a little. Ten-ton artillery shells sounded like a lot, but you have to know that a small-sized artillery shell weighs dozens of kilograms. After a little conversion, these ten-ton artillery shells are only two hundred kilograms. The number between [-] and [-] is really not a big number, that is, the number of volleys fired by the Soul Guide Legion.

Looking at Gu Rong's somewhat suspicious eyes, Zeng Yixin shook his head and explained: "This is a serious alchemical product. It is known as a weapon made of chlorine trifluoride, a taboo fire that cannot be touched in alchemy. It is made of three It is composed of a fluorine atom and a chlorine atom, and the two are extremely electronegative. Even if they are barely combined together, it is an extremely unstable alchemical form."

"To put it simply, its external performance is that this thing will crazily plunder all electrons from the outside world. Do you understand now?"

Gu Rong listened carefully to every word Zeng Yixin said, and then shook her head heavily, still not understanding.

Zeng Yixin collapsed and covered his forehead. He remembered that he had written Gu Rong's name on the list of sect elders who had arranged for tutoring in basic subjects, in order to help these elders in the sect who did not understand modern scientific concepts at all. Let's learn some new knowledge, so as not to chat with the juniors in the sect and ask questions. Now it seems that Gu Rong is most likely skipping classes.

Zeng Yixin thought again that Ning Rongrong seemed to be responsible for this matter, and instantly understood what was going on.

In the past, it was Ning Rongrong who played rogue with Gu Rong and Chen Xin, but now it was finally Gu Rong's turn to act rogue.

"Its boiling point is 11.7 degrees Celsius, which is less than [-] degrees Celsius."

Zeng Yixin explained.

"I know this. The boiling point of water is one hundred!"

Gu Rong finally heard the area he was familiar with and quickly spoke, but then his pupils suddenly shrank.

It has a boiling point of less than [-] degrees Celsius. What kind of monster is this?

"Chlorine trifluoride shells can burn substances that we generally think cannot be burned, including but not limited to asbestos, sand, glass and even burned ashes."

What a terrifying alchemical product.

Gu Rong raised her eyebrows and couldn't help but have a bit of respect for Dugu Bo, a weirdo who kept himself bored in the laboratory every day.

But then, Gu Rong thought of something very serious.

"Since the wizards among these undead soldiers can use frost to create a thick layer of natural armor for the undead army, what if they can use spells such as rainfall? Wouldn't it still be a useless effort?"

Zeng Yixin's smile when she heard this question made Gu Rong shudder: "Who told you that water is incombustible?"

"It would be fine if these wizards didn't try to use rainfall spells. Once they try to use rainfall spells to extinguish the flames, not only will the rain burn instantly, but it will also produce highly toxic hydrofluoric acid. This stuff is not just harmful to humans. It’s highly poisonous, even to the undead.”

"The temperature of these flames can reach up to [-] degrees, far exceeding the so-called ultimate fire of [-] degrees. It can not only ignite water and even ice, but even this so-called royal city will also be ignited. It is a pity that I only have ten tons of artillery shells on hand, but that’s enough. If they can’t kill the enemy after firing these ten tons of artillery shells, then we will have to do it ourselves.”

Zeng Yixin got up and walked towards the military camp. Although this substance is extremely dangerous, fortunately it is not difficult to store it. You only need to use ordinary steel or aluminum to store it. These metals will produce chlorine trifluoride the moment it comes into contact. A dense fluoride film blocks further reactions.

Since the opponent cannot be attacked for a long time, Zeng Yixin is also interested in testing the power of this chemical alchemy reagent with the help of the coalition forces. If the effect of this thing is as good as the paper data, it will be more valuable than the adhesive alchemy bomb that Dugu Bo made before. Too much.

At least in terms of range damage, if the adhesive alchemy bomb can easily kill ordinary soul emperors and even soul saints like ordinary titled Douluo, then this new type of alchemy bomb made of chlorine trifluoride Even Dugu Bo, who was level 97 and had cured his stubborn illness, was not only extremely lethal to high-level soul masters, but at the same time, if he unleashed a single blow of poison, he could easily wipe out an entire city or country.
