Chapter 8: Monosulfur, dinitrate, carbon and some sugar. Big Ivan

Half a month later, Li Fei was practicing Su Zhen, the basics of kendo, in his training ground with a 300-pound tungsten steel rod.

The strength of three hundred kilograms is already close to the power of a great soul master in the second level of the assault system. It is conceivable that Li Fei's physical fitness has now reached the level of a great soul master. As long as he trains for another year and his mental power is condensed enough, he will be the best in a thousand years. Ring is not a dream.

As a time traveler, Li Fei is not pedantic. He only wants to use martial arts to fight, so he plans to use sword skills to fight when the martial arts' attack power is not strong in the early stage.

The swordsmanship in this world all involves soul skills, which are basically in the hands of aristocratic families and sects. Even if the Li family has money, it is difficult to buy them. They can only continue to do what was called basic Su Zhen in the previous life, and still Collected some combat sword skills in the army to enhance your future combat capabilities.

Li Fan next to him also held an iron rod, but it only weighed 200 kilograms. He was practicing the stick skills collected by Li Fei, and he was also dancing like a tiger. Every time the stick was hit, there was a sound of breaking through the air. It can be seen that His current strength is not weak.

"Come on Li Fan! My brother is not tired even if he wields a three hundred kilogram iron rod. I only weigh two hundred kilograms and I can't train in less time than my brother!"

Feeling the pain in his arm, Li Fan kept cheering himself up in his heart, and his eyes when he looked at Li Fei were full of admiration, admiration and envy.

The training arrived at noon, and after the two of them finished the nutritious meal prepared by Shen Chenyan, Li Fei asked Li Fan to take a medicinal bath, while he went to a small room in the northwest corner of the manor.

When you open the door, you will see a small workbench with some grinding and filtering equipment, as well as a lot of black powder and round iron balls.

"After all, I was also a student at a university in my previous life. Even though the knowledge has been returned to the school, I still remember clearly the words "one sulfur, two saltpeter, three charcoal and a little sugar, Da Ivan".

"It will definitely work this time!"

With a confident look on his face, Li Fei skillfully stuffed the black powder into the iron ball, stuffed some iron filings, picked up the sugar that had been prepared nearby, and poured in twice the amount of black powder. This is what he went through. The results of multiple tests!

Carefully sealing the thin iron balls, Li Fei weighed them in his hand, made two more, and quickly came to the training ground and looked at the scarecrow target in the distance.

The soul power was injected into the iron ball, compressed into a small point, and thrown near the scarecrow. The soul power exploded instantly, igniting the gunpowder inside.

"boom!"

A huge explosion sounded, resounding throughout the entire Li Mansion, and the ground trembled slightly. Li Fei could not stand still and sat on the ground. A thick smell of gunpowder came over the ground. Li Fei looked and saw the explosion. A large hole with a diameter of two meters was left in the place, and the scarecrow disappeared, replaced by grass clippings everywhere.

A figure came from a distance, it was Li Ming who heard the sound.

"Fei'er, are you okay?!" Li Ming used the Soul King's speed to the extreme, ducked to Li Fei's side, and asked worriedly.

"I'm fine!" Li Fei shook his head, pointed to the big pit in the distance, and showed an excited look: "Dad, I succeeded!"

"Success?! It's the bomb you mentioned before!" Li Ming said uncertainly.

"Yeah!" Li Fei nodded crazily: "Dad, show me how powerful this thing is, so I can use it as a reference!"

Li Fei still had little knowledge and could not estimate the power of the soul hybrid version of the grenade he had made. He also needed Li Ming to make a reference.

"Okay, then throw one out and let me see!" Li Ming also wanted to see the power of the weapon made by Li Fei, which could actually blast a two-meter hole.

"Dad, keep an eye on it!" Li Fei looked confident. He put his soul power into the homemade grenade and threw it into the distance. With a "boom", a huge pit appeared on the spot. Pieces of iron filings flew in all directions at an invisible speed.

One of the fragments shot directly near Li Ming, leaving a large bullet hole.

Drops of cold sweat dripped from his forehead. Li Ming mechanically turned his head to look at Li Fei and stammered: "Fei'er... this thing... was really... made by you..."

"Well!" Li Ming asked with a serious look on his face: "Dad, how powerful is this grenade?!"

"Your father has seen the Soul Saint before. The power of this thing should be comparable to the ordinary soul skills of the Soul Saint. The average Soul Saint will probably be seriously injured if he is unprepared!"

Li Ming took a few deep breaths to calm down, thought for a while, and gave the answer based on the strength in his memory.

"The talented Soul Sage is not as good as Tang San's hidden weapon. What a failure!" Li Fei murmured in a low voice with some displeasure. A completely mechanical hidden weapon, Buddha Fury Tang Lian, could kill several Soul Sages. His own The power of a grenade filled with gunpowder and soul power is actually not comparable.

In fact, he also wants to know what kind of mechanism can make the power of some small blades shoot out to kill Soul Saint. Even if the blade material is good, the kinetic energy when shooting is insufficient, there is no way to hurt people!

It can only be said that it is indeed a sect in the world of martial arts, and there is always some knowledge that people cannot understand.

"Fei'er, what did you say?!" Li Ming didn't hear clearly and asked in confusion.

"It's nothing, just a little disappointed!" Li Fei shook his head quickly.

"You are still disappointed with this power. If we had prepared a few more at once, the Soul Saint would probably have been killed too!" Li Ming looked stunned, unable to understand his son's thinking.

"Forget it, dad, let's not talk about this anymore! I will give you the production method later, and you can ask someone you trust to make some for emergencies."

"Okay, I'll make the arrangements right now. With this thing, we can go a little deeper when we go to the Star Dou Forest to hunt for soul rings."

Seeing that Li Fei didn't want to say more, Li Ming didn't ask any more questions.

The two came to the workshop. Li Fei wrote a copy of the method of making grenades to Li Ming, and gave some instructions on how to preserve the gunpowder. Then he returned to his bedroom to continue studying ways to open the meridians.

"The grenade has been solved. I will concentrate on training and research in the next time to prepare for the soul hunting in a year."

With a killer weapon like grenades as a trump card, many dangers in the early stage can be avoided, which allows Li Fei to relax and concentrate on training and studying how to become stronger.

Li Ming took the manufacturing method and found a few craftsmen. He asked these people to start manufacturing according to Li Fei's instructions. He did the last step of filling himself, and the craftsmen didn't know the proportions. In the end, they not only made some small ones, but also made There are several ones with a diameter of one meter.

After receiving these grenades in the storage space, Li Ming took all the craftsmen's families over and asked them to do some chores in the manor.

Several craftsmen also knew the reason why Li Ming did this, and each one of them swore that they would never leak the grenade manufacturing process.
