Behind me is the entire history of mankind!

Chapter 56 Full Service Announcement
The girl named Mercury raised her head in a daze, looked up at Lincheng who was holding a compound bow in a standard posture, and then looked at the dead body of Apophis, who had lost her breath of life, and remained silent.

"I'm blowing this game up!!!"

After a brief silence, after confirming that the monster was completely dead, a burst of cheers erupted from the entire low wall of the bastion.

Some people like to pursue stimulation because they like the sense of satisfaction after being stimulated, that is, they like the pleasure that the sudden increase of adrenaline brings to their whole body, the feeling of rapid heartbeat and numbness of the brain. In this case, people can basically Forget everything and just feel some kind of supernatural pleasure.

And games are a way to get this kind of excitement.

When the monster was about to approach just now, the imminent sense of crisis, whether the bed crossbow could be shot, and whether the monster could be killed, all became the source of this excitement.

This made these players feel extremely satisfied, especially Li Ge and Heygou, who were being chased, let out a big mouthful of foul air.

"Not to mention, Lincheng, I would like to call you the Rider God, the arrow just now was so handsome!" Brother Li shouted excitedly.

His physical fitness is twice that of ordinary people, not only his physical fitness, but his perception and reaction speed have also been improved accordingly. Therefore, for him, actions that he could not complete in the past can now be done with this body. Can be done easily.

"Hey! Brother Li, didn't you guys go shopping? Where did you get this thing?"

From the beginning to the end, he held the jerky in one hand, chewed the jerky, and asked while standing on the high wall.

"It caught up by itself, and it didn't know where it came from."

"This thing should be Apophis." The monster looked at the distance from the beginning to the end and said with emotion, "I thought it was just a background, but I didn't expect it to be installed. The design is really good."

Brother Li looked at the pile of corpses behind him, the blood-red silk thread no longer twitched, but turned into hair and scattered around his body, his huge mouth was slightly open, and blood with a foul smell flowed.

He shivered slightly, stopped looking at it, but grinned, and patted the machine gun on the car at the player above.

"See! This thing, and this car, our trophies! And this gun, we still have a car behind, dozens of guns!"

"Where did you go this trip? It's a fat wave." Blitz Poland said enviously.

"Wait until I write a post tonight, listen to me blowing it slowly. Bah! Take it easy, I'll post the video on the community by the way, it's really fun today!" Brother Li said excitedly.

After a pause, he looked around and found that the trench had been dug almost into shape, and the car couldn't get through it at all, he said.

"Dig it, can you dig like that in a day? The groundhog is reincarnated?"

"How do you talk." He said displeased from beginning to end, "Can a groundhog dig so fast? This must be the reincarnation of an excavator?"

"Hey, we really have an excavator." Blitz Poland smiled, and pointed not far away.

There is a small iron-wood mixed machine parked there. The structure is very simple, consisting of a wooden operating compartment and an iron-wood mixed mechanical arm.
It is not the hydraulic structure of modern excavators, but a very simple transmission structure with wire ropes and gears. The iron-wood arm and the mechanical arm of the shovel present an X-shape, some of which are still in some mines. Excavator with electric shovel structure in the field.

"What did you do?" Brother Li said in disbelief.

"We cut the wood." Blitz Poland said.

"Tesla dismantled a transporter and repaired its engine, Da Vinci used that engine and the steel of the transporter to make this thing." Said from beginning to end.

"Where is your door?" Lincheng asked, "I'll drive in."

"To the side, there's a hidden entrance there."

After driving the car into the inside of the bastion, Lincheng's eyes suddenly felt a little dazed, as if he had left for several days instead of a day.

A simple wooden house has already been built on the open space, and the overall bastion structure is 50.00% complete. There are also latrines, biogas pits, and some blast furnaces for calcining cement and steel.

"Phew, I'm exhausted. I've had a great time playing today." Li Ge got out of the car and exhaled lightly. It's not that he was physically tired, but that the continuous stimulation made him mentally exhausted. He patted Lincheng on the shoulder, "I'll be offline first, it's time for my wife to wake me up."

"I'll go down together too." Heygou said, and then the two walked to the origin base together.

Mendeleev was sitting with Jiang Ye in front of a reactor and tinkering with something. The reactor should be something in the chemical laboratory in the base. I don't know why it was moved to the ground.

But after getting close to Lincheng, you will know.

"Put the nitrated asparagus cellulose together with the stabilizer diphenylamine, ethyl acetate and gelatin into the reaction kettle, heat up, stir into a ball, press into a flat ball, and then passivate and gloss the finished ball flat propellant. .” Jiang Ye murmured.

Wood acetic acid can be obtained by dry distillation of wood, and acetic acid can be extracted.Use ethanol, concentrated sulfuric acid, add acetic acid at the end, and then heat to get ethyl acetate, while gelatin is partially degraded by collagen in connective tissues such as animal skin, bone, sarcolemma, muscle, etc., and becomes white or light yellow. Translucent, slightly shiny flakes or powders;
"The second half can be done with ether particles, it will be safer." Mendeleev murmured softly.

They opened the reactor, and Mendeleev stretched out his hand. Under the radiance of ether particles, the viscous matter in the reactor gradually turned into a pile of dry spherical propellants.

"Are you making smokeless gunpowder?" Lincheng asked.

Mendeleev and Jiang Ye looked up at Lincheng and nodded.

"What happened outside?"

Mendeleev asked, they still heard the big movement just now, but their experiment was at a critical stage, so they didn't pay attention.

"It's all right. Did you succeed?" Lincheng asked.

"It should be successful. Now it's just a matter of putting it in a bullet and shooting it with a gun." Jiang Ye said.

Lincheng seemed to have thought of something, and took out a bullet bought under the double tree from his body and handed it to Jiang Ye.

"There's a bullet here."

Jiang Ye's eyes lit up, he took the bullet, disassembled it, poured out the propellant inside, poured in the propellant they had just made, and handed it to Lincheng again.

"You try it."

Lincheng took the bullet, loaded it into the magazine, then pulled the breech bolt to load it, and fired a shot at the wall of the bastion not far away. into the earth wall.

"It seems to be different from the original gunpowder in this bullet, and it's more powerful." Lincheng said.

"Of course it is different. This is a new technology. The smokeless propellant produced by this method can improve the combustion performance of the propellant, reduce the amount of charge, simplify the operation and shorten the production cycle." Jiang Ye said excitedly, "and the cost of raw materials Much lower cost than cotton."

"Good job, I read you right." Mendeleev smiled, "Continue to use your knowledge to contribute to the base."

"Yes!" Jiang Ye said happily, and at the same time, at this time, there was an additional server-wide announcement in the UI system announcement of all players.

[The player "Yild Daddy" created "Smokeless Gunpowder", obtained six achievement points, and entered the achievement list. 】

"The wild god is really playing big."

Those who were still looking at the corpse of Apophis not far away on the city wall said with emotion when they heard the announcement from the beginning to the end.

"The last time I changed my job as an alchemist, there was an announcement for the whole server, and it came again in just a few days." Blitz Poland said enviously.

"Damn, when I have the materials, I'll just build an internal combustion engine for you to see!"
