Behind me is the entire history of mankind!

Chapter 54 Smokeless Gunpowder
"Whoa, whoa, whoa!!!"

The car rushed out of the forest suddenly, and suddenly flew into the air. The terrible weightlessness made Brother Li, Heygou and the little girl shout in different languages.

With the sound of Peng, the car hit the ground heavily, making people worry whether the car that was put together from many parts would fall apart due to the impact.

The vibration almost threw Brother Li and Heygou out of the car, but even if they were thrown out, it was fine, it was just consumables.

And, at this moment, they were even extremely excited.

"It's so fucking exciting!"

As they fell, the huge monster also rushed out of the forest, and knocked down several big trees by the way, with that ferocious smile still on its face.

"That's Apophis?" Li Ge said, "My dear, I'm getting goosebumps, this art is too awesome.

Look at the bloodshot, just like using Rejoice, it is really elegant.

The twitching bloodshot, the huge human-like smiling face, and the spider-like legs grew on my spots everywhere. "

"It's not just your point, my goosebumps have also arisen." Heygou said.

"What are you still doing, isn't there a machine gun behind you? Shoot it!" Lincheng shouted.

"Oh!" Brother Li quickly touched the machine gun, controlled it to turn around, aimed at Apophis and pressed the trigger.

The machine gun spewed raging flames, but unfortunately because it was the first time it was used, and both sides were moving at the moment, the first few rounds were almost empty and hit the tree trunk on one side.

However, the marksmanship was not good, and the rate of fire was improved. In the end, dozens of shots hit the body of the Apophis, and the black and red liquid bloomed.

Apophis let out a weird roar, not like any creature on the earth. It stopped for a moment, but it still didn't die. Even after it eased up, it started chasing the jeep again. Once faster.

The grin on his face disappeared, but was replaced by a more ferocious killing intent.

The rate of fire of the machine gun is already fast, and it seems that it can use a long time of bullets to finish shooting in this round of shooting. Li Ge and Heigou hurriedly picked up the ammunition belt on the ground. They have been busy for a while, but they have not succeeded. The belt is mounted on the machine gun.

"Fuck! How do you load this machine gun bullet!" Brother Li shouted.

"Who knows!"

"Throw the Molotov cocktail!" Lincheng shouted.

"It's so far away, ghosts can throw it!" Heygou shouted.

"The Molotov cocktail is useless." Quicksilver said at this moment, "Apophis is not afraid of flames, and bullets are useless to it. You people, there is no way to kill it."

"She's right, Lincheng." Nuwa's voice rang in Lincheng's ears, "Although the data about Apophis is missing, the observed data is indeed like this. Its weakness is that the eyes and mouth."

"Lincheng." Einstein's voice came, "Its corpse is useful to us. Lead it to the vicinity of the base. Da Vinci made a temporary thing, which should be able to deal with it."

"I understand." Lincheng replied.

He turned his head and looked at the girl on one side. She was curled up in a corner with lowered eyes, shrouded in darkness, making it impossible to see what was going on in her heart.

She seems to have been through a lot of this, no fear, no panic
"In this world, there has never been an unkillable monster." Lincheng said.

The girl raised her head and watched him quietly.

Lincheng didn't explain, but under the astonished eyes of Shuiyin, he actually slowed down the speed of the car so that Apophis behind him could follow them closely.

At the same time, the bastion above the origin base is still as hot as the previous few days. Lincheng modified the mission system and shifted the current main focus to building the bastion.

Therefore, there are many more people digging trenches with hoes and shovels in the base than in the past.

Of course, in addition to completing the tasks released by the base, Lincheng also gives these players a high degree of freedom. They can use their knowledge and resources to complete actions that can lead to civilization progress, such as steelmaking and iron refining. .

The first successful player can get the corresponding achievements, and the achievement points can be exchanged for military merit in equal proportions.

For example, the first animal tamed by Hu Lun received corresponding achievements.

And the military merits exchanged for achievement points are obviously very impressive, at least much better than digging holes, because Lincheng encourages this kind of behavior.

Those with brain power will contribute brain power, and those without brain power will contribute physical power. After all, the basic industrial system is too simple for those scientists, and their energy can be transferred to other places, to more advanced scientific research.

Although the level system has not yet been opened, and the more exciting battle plot has not yet been opened, but the farming method is still very popular among these players.

Under this reward mechanism, the cesspit was dug by the players, and even a biogas digester was sealed with cement.

"Mentor, I have found a material to replace cotton to make nitrocellulose!"

Excitedly, Jiang Ye held a pile of grass and found Mendeleev, who was trying to practice steel with local methods, and shouted. After becoming Mendeleev's assistant, he naturally called him a mentor.

Mendeleev looked at the thing he held in his hand with a little curiosity, "Is this a rush?"

"In our country, this is called asparagus." Jiang Ye said, "The cellulose content of this grass is more than 60.00% 90.00, although it is not as good as [-]% [-] of cotton, but it should be able to refine the fiber after pre-hydrolysis and saponification. white.

Using rosin as saponification agent, the moisture absorption of refined asparagus cellulose can be increased by 2 to 3 times, which can greatly shorten the nitrification reaction time and increase the product yield. "

Mendeleev thought for a moment, then nodded, "If it is really feasible, compared with cotton linters as raw materials, the cost can be reduced by at least 15%."

This thing can be seen almost everywhere as long as it is by the stream or river.

"21%."

Jiang Ye said with certainty that this thing is the raw material of rayon. He also specifically asked a colleague in related fields and learned everything about this kind of thing. This is an industry with quite mature technology.

Although Mendeleev may have a higher IQ than Jiang Ye, Jiang Ye also had inherent advantages in those hundreds of years when he was born late.

For the two, they are not so much a teacher and student, but more like a relationship between a teacher and a friend.

"I just used the oil in the base to produce diphenylamine. I basically have the materials needed. You first use this thing to make nitrocellulose, and I will make the rest of the things you need. You have the container needed for pre-hydrolysis ?"

"I just got a wheel a few days ago. It's made of aluminum alloy. I can make it with ether particles."

Mendeleev nodded, then turned and walked to the base, he wanted to make the rest.

"Wild God seems to be refreshing another achievement point."

At this moment, the main person in charge of the bastion work of the base sat on one side to rest from the beginning to the end, listening to the conversation between the two, he said with emotion, as one of the first few people who entered the game, he is also known in the game. The first person to obtain a hidden job will naturally become a great god.

And also because of his game ID, naturally there are more people who are willing to be called God than Dad.

"I heard that he seems to be a doctor of chemistry. The achievement point of playing this game is not to sprinkle water." Blitz Poland said from the beginning to the end.

After a pause, he continued to laugh, "Now I regret that I didn't study hard before."

"Fart! My academic performance is good, but I just went astray and was brainwashed by the infrastructure madman, so I went to study civil engineering."

He sighed all the way.

He looked at the blueprint in his hand, "When I build this thing, I will earn no less than him."

Blitz Poland looked at the design drawing curiously, "Hey, this thing is as complicated as a twist. What's the use of building such a troublesome wall? The wall is not high."

"What do you know! This is called a bastion, which can provide the defenders with firepower without dead ends, and the attackers have nightmares!" From the beginning to the end, he actually only learned about it not long ago.

He looked at the blueprint and said, "To be honest, the more you think about this blueprint, the more amazing it becomes. Sometimes the wisdom of these ancient people is really no worse than that of today's people, but they were born in the wrong era."

"Isn't this designed by Da Vinci?" Blitz Poland said.

"Similar technology existed before, but Da Vinci made some adaptive transformations." He said from beginning to end, "Wild God is right, these NPCs are really smart, much smarter than us, you see there."

Pointing not far from the beginning to the end, Nan Sheng was standing in front of the drawing board, holding an oil paintbrush and drawing on the drawing board. The drawing board, drawing paper and paints were all lent to her by Da Vinci.

"Is that Nan Sheng?"

For the few girls in this group, Blitz Poland is still fresh in my memory.

"What is she doing up there?"

"I heard from Jie Se that she studied painting, and this year she is going to be admitted to CAFA as a high-achieving art student. After seeing Da Vinci's paintings, she wants to worship him as a teacher. Now she draws paintings that satisfy Da Vinci.

Painted there early in the morning. "Said from beginning to end.

"Then the NPC will still teach painting?" Blitz Wave said with his eyes wide open.

"I still think that people are NPCs in ordinary games. They are all virtual reality games and their imagination is not high. Brother Ye, who has a doctorate in chemistry, is called Mendeleev Mentor. What do you think?"

"Tsk, this game is amazing, don't tell me it wasn't made by aliens." Blitz Poland said.

"Never mind him, it's not something we should worry about, just play with it."

Looking at the bastion gradually built in front of him from the beginning to the end, he sighed.

"This game is really not ordinary fun. When watching this bastion gradually take shape, the sense of accomplishment is higher than those high-rise buildings I participated in building."

Blitz Poland was thoughtful, "Mendeleev is trying to train steel with local methods. I want to try to see if I can build an internal combustion engine. The air tightness and precision can be solved with alchemy. As long as there are materials, maybe really do.
What materials do internal combustion engines need? Aluminum alloy is better for heat conduction for cylinders, and aluminum alloy is required for some parts, as well as cast iron and some alloy steel. "

"Okay, where did you graduate from?"

"Wudaokou Vocational and Technical College."

"Me too!" He said pleasantly from the beginning to the end, "I didn't expect that we are still alumni!"

"It would be really cool to have an internal combustion engine, and this crane could be automated."
