Douluo: I heard that Disaster is a waste?

In the next few days, Qian Yuehuan stayed by Biji's side.

The broken bones are recovering and growing little by little. It feels strange and comfortable, cool and just like lying on an iceberg in the hot summer.

Qian Yuehuan did not waste these few days, but took out his gunpowder gun from the gold ingots to study it.

Some time ago, she used a gunpowder torch to deal with Bu Le and Tian Ya, so she knew the level of the gunpowder torch she made.

In front of ordinary people, gunpowder can easily kill the opponent, but in front of a Soul King of more than 40 levels, he can use soul power as a defense. At most, it will blacken the skin and explode the flesh and blood on the surface, but it will not cause any fatal injuries.

Qian Yuehuan also wanted to make a pistol, but she didn't have soul power and couldn't grind out hard bullets, so Qian Yuehuan studied gunpowder guns with a wide attack range.

The formula of gunpowder is one part nitrate, two parts sulfur and three parts charcoal. It can easily kill hundred-year-old soul beasts or soul masters below level 20. However, thousand-year-old soul beasts and soul masters over level 20 have the ability to resist, and if not handled properly, it may anger the opponent and cause them to retaliate.

After much deliberation, Qian Yuehuan decided to modify the gunpowder formula in terms of recipe and proportion.

Charcoal, sulfur, and saltpeter were replaced with high-end materials. After all, these three materials were obtained by her in the human world, and the gunpowder guns made were also low-end versions.

The venom of the green sulfur python is highly corrosive, and Qian Yuehuan uses it as a substitute for sulfur.

Saltpeter must be replaced by the saltpeter vine that grows on the Mingxuan Turtle. The saltpeter vine is a parasite, but its shell is similar in material to saltpeter.

Qian Yuehuan divided the materials into several portions, each portion was formulated differently, and the powders were put into a sealed official kiln and baked at high temperature.

three days later

Qian Yuehuan finally heard a "bang" explosion. The sealed official kiln was blown into pieces by a huge force. The scorching high temperature ignited a flame, affecting a range of more than ten meters.

The noise was so loud that many of the surrounding soul beasts were blown out, looking at Qian Yuehuan with resentful eyes.

Hold back, don't fight, the other party has a backer! If you fight, you can't afford the compensation!!!

Qian Yuehuan nodded in satisfaction after seeing the effect. The new gunpowder was much more powerful. Many thousand-year-old soul beasts were trembling on the edge of the gunpowder. The skins of some soul beasts were baked into carbon by the heat, indicating that the gunpowder made them feel threatened.

If the soul beast's cultivation level is converted into that of a soul master, it can cause fatal damage to a level 30 soul master.

However, this newly configured gunpowder reacts slowly. It takes a full twenty minutes for it to react and explode with powerful force. Qian Yuehuan's next step is to find a catalyst to speed up the reaction.

However, this is also one of Qian Yuehuan's trump cards. From now on, Qian Yuehuan has free time to modify hidden weapons.

Although Tang San's hidden weapons are good, they are not as good as the hidden weapons made later. At that time, Tang San had not yet practiced the skills of the Clear Sky Hammer, and the manufacturing of the hidden weapons could not meet the precise standards. Even the silver needles were a bit rough and not sharp enough.

Since the hidden weapon was not made well enough, Qian Yue Huan used speed and other means to assist. The faster the speed, the greater the attack power, the longer the range, and the deeper the silver needle could penetrate into the body.

Qian Yuehuan added a small groove above the buckle of the hidden weapon, put powder in the groove, and used the principle of air friction combustion to burn part of the powder to produce surging gas. The air pressure increased, thereby quickly pushing the silver needle to shoot.

Qian Yuehuan also smeared the venom of the three-leaf green snake, which had cultivated for thousands of years, on some of the silver needles. Once the venom touches the flesh and blood, it will cause the blood to coagulate. Unless the flesh and blood contaminated by the venom is cut off or there is a high-level healing soul master to treat it, the enemy can only wait to die.

Qian Yuehuan decided to name this newly modified hidden weapon Qingye Dingnu, which is suitable for sneak attacks.
