Rebirth of the Alchemy Emperor: The Road to the Nine Heavens Supreme

In the future, they will go to the big cities, sects, forces, and families in the center of the central region to earn spiritual stones and spiritual materials. The higher their cultivation level, the safer they will be there, and the more spiritual stones and spiritual materials they can earn.

So next, they kept looking for cities where beast tides and wars had occurred. When they found them, Lu Xuan opened a time and space tunnel and let the Chaos Tree absorb the energy, blood and soul power below.

If the energy, blood, and soul power needed for the three of them to practice were insufficient, Lu Xuan would use the Demon Refining Tower and the Infinite Bowl to absorb some for the three of them to practice.

Of course, while the three of them were practicing, they also refined some elixirs, spiritual weapons, and carved some talismans and formations in order to sell them in big cities to earn spiritual stones and spiritual materials.

Lu Xuan opened the space-time tunnel and absorbed the blood and soul power of the battlefield below. Naturally, he also detected the tragic scenes on the battlefield.

Especially in those cities that were attacked by monsters, almost everyone in the city would be killed or kidnapped by the monsters.

Countless old people and children were eaten alive, and the scene was horrific.

But it had already happened. Lu Xuan could only watch, but he could not prevent this tragic thing from happening.

If he dares to stop it, it will definitely cause the collapse of that time and space, and will also cause the collapse of the time and space where they are.

In fact, Lu Xuan knew that there was a way to prevent the collapse of time and space after preventing that tragic thing from happening——

It is to use the magical power of time and space to support.

The so-called magical power of time and space support means that you changed something that has already happened in a certain time and space in the past. As long as you use the magical power of time and space to support the people, things, and objects involved, the space and time above will not collapse.

For example, you go to a certain time and space in the past and kill a child.

Because this little child died before giving birth to a son, the son he gave birth to and the descendants who followed him became water without a source and a tree without roots. Then these descendants are living in a world where The space will collapse, forcibly erasing all those descendants.

And if you use time and space to support your magical power and support all the time and space above this child, then these time and spaces will not collapse, and the children's descendants will not be forcibly obliterated by time, space and heaven.

Originally, Lu Xuan could also use the time and space support magical power, but unfortunately, now his cultivation level is too low and his strength is too weak. He simply does not have enough strength to stop the monsters from slaughtering the city in the past time and space, and then use the time and space support magical power to put that The entire city's time and space are supported.

Not to mention going to that time and space to do these things, his current time and space tunnel magical power can only create a tunnel the size of a teacup, and he can't even go to that time and space now.

As for implementing the magical power of time and space support, Lu Xuan guessed that what he could support now would probably not be much larger than the time and space the size of a teacup.

After all, supporting an extremely heavy space-time requires much more strength than building a space-time tunnel.

What has happened in the past has happened. When monsters massacre the city in the future, what method should we think of to help the city defenders defeat the monsters and prevent them from massacring the city?

Lu Xuan actually didn't come up with this idea now. He had this idea in cities such as Sunset City and Peony City that Lu Xuan had visited and were attacked by monsters:

How to help the people in the city resist and defeat the attacks of monsters.

In fact, Lu Xuan has many ways to kill enemies:

Use elixirs, spiritual weapons, talismans, seals, array disks, etc.

For example, he refined the Thunder Explosion Pill, a Life-Destroying Pill, the Three-Step Soul-Destroying Pill, as well as all the weapons, Pyroblast Talismans, Killing Formation Disks, Formations...

It's a pity that these methods are either like elixirs such as the one-step life-killing elixir. Because the medicinal materials are too rare, it is impossible to refine them in large quantities to prevent monsters from attacking the city.

As for other things, including the Pyroblast Talisman, Thunder Explosion Pill, Three-Step Soul-Severing Pill, various weapons, and array disks, they are only suitable for small-scale close combat. If you deal with a flood-like tide of beasts, even if these things can The monsters in front of you are blown up and poisoned to death, but there is nothing you can do about the monsters in the distance.

Regardless of whether the Thunder Explosion Pill or the Pyroblast Talisman is thrown, it cannot be thrown far away.

When the beasts attack the city, the monsters in front are originally used as cannon fodder:

Even if they are not killed by explosions or poisons, they are still used to hit and bite formations and city walls, use their bodies to block human swords and weapons, and consume the strength of human warriors.

Of course, if the soldiers guarding the city could become invisible like Lu Xuan, and scatter large amounts of Thunder Explosion Pills, Pyroblast Talismans, and poisons into the beast tide, and make a sudden attack, they would also be able to prevent the beast tide from attacking the city.

However, such a sudden attack is only suitable for once in a while. If it is used frequently and the monsters are used to this attack method, the effect will not be too great:

You must know that there are many ninth-level and eighth-level monsters among the monsters.

Even if you are invisible, driving a spirit boat or flying in the sky, and throwing these pyrotechnics, thunderbolt pills, and poisons over the monsters, those monsters above level [-] can gather energy. Even if they can't see you, they can shoot blindly. I can hit you even if I hit you randomly.

Invisibility only means that the body is hidden and invisible, but it does not mean that the body actually disappears.

Last time in Sunset City, Lu Xuan first poisoned the ninth-level and eighth-level monsters to death, and then attacked suddenly. The monsters were caught off guard and without command, and they retreated.

If these monsters were on guard at that time, and the eighth and ninth level monsters had not gathered together, they would not have been able to poison them all at once.

Even if ten or eight are poisoned to death, the remaining high-level monsters can still direct the beast tide to attack.

Moreover, all the monsters above level [-] condensed their big hands of energy and slapped them at the place where the Thunder Explosion Pill and Pyroblast Talisman were thrown. They could easily hit Lu Xuan's spirit boat.

It is necessary to develop a weapon that can hit a long distance like a spiritual cannon, but does not consume much of the warrior's soul and physical strength.

In the God Realm, the weapon refiners once refined a kind of spiritual cannon.

This kind of spiritual cannon can be installed on a spiritual boat or placed on a city wall, etc. It is a powerful weapon for killing enemies:

Its attack range can reach hundreds of miles.

The energy it emits will be blasted to pieces wherever it passes, whether it is creatures, houses, trees, or stones.

When dealing with monster attacks, if there are thousands of spiritual cannons to bombard the monster tide, then in the blink of an eye, the monsters within dozens or hundreds of miles will be blown to pieces.

But this spiritual cannon also has a shortcoming, that is, it consumes too many spiritual stones:

A single bombardment would cost hundreds of thousands or millions of spiritual stones.

No one can afford this expense.

If the value of the bombardment object is low, it is not worth the cost of firing a spiritual cannon.

Therefore, even in the God Realm, spiritual cannons are used in the most important and critical places.

Is there any way to reduce the cost of firing the spiritual cannon?
