Li Sheng looked at the clear liquid in the beaker, and his whole body seemed to be exhausted.
“Finally done!”
This liquid is none other than... sulfuric acid!
Sulfuric acid sounds scary, and in news about Li Sheng's previous life, it often appears as a tool for committing crimes.
But in fact, in industry, this is one of the most important raw materials, and one of them can even be eliminated. This is the most important material.
With sulfuric acid, various chemical materials can be prepared through oxidation and reduction, various reactions...
Of course, Li Sheng had made this stuff before, but the purity was too low.
Standard industrial concentrated sulfuric acid is 98%, but what he produced is basically less than 50%.
However, after a period of hard work, time has gradually entered summer.
By this time, Li Sheng finally prepared standard concentrated sulfuric acid!
Apart from anything else, this thing is perfect for making glass.
When the time comes, put some perfume on it and stuff it into Zicheng Zhai——
Li Sheng could guess what the scene was like.
Explode!
This is only a preliminary application.
In all subsequent chemical industries, sulfuric acid is the most important one.
And with sulfuric acid, nitric acid can be made.
With nitric acid, hey...
Li Sheng can make real fried yao, and there is no need to deal with fake fried yao such as compressed black fire yao.
Moreover, nitric acid fertilizer is also a good thing.
Highlight an advanced one!
This pile of things was finished last night, but Li Shengda, who was excited, still wanted to take a look early in the morning.
This is just like getting high marks in the college entrance examination and saving money to buy a new car. You have to look at it every day to feel comfortable.
At this time, Mian'er Ying'er was already urging her outside.
Li Sheng responded, "Come right away!"
At this time, Li Sheng was dressed in black, just like when he went to Chang'an to participate in the piano duel event.
As for the day's itinerary, it was not to go to Chang'an, but Li Sheng promised Mian'er Ying'er that he would have a holiday on the first day of April so that everyone could go hunting together to build a group.
Mian'er Ying'er had never heard of the novel word team building, but she knew that the young master wanted to take them out to play.
So I woke up excitedly early in the morning and dressed up.
Li Sheng wanted to reminisce about last night's excitement, and the two maids wanted to dress up. This early morning time was wasted until ten o'clock before setting off...
But luckily the weather is good!
At the turn of spring and summer, the sun is bright and picturesque.
Li Sheng took his two maids, bathed in the spring sunshine, and galloped their horses outside Youzhou City. It was so pleasant...
"You two work hard and learn more. Now we can only ride dwarf draft horses. In the future, you will learn a skill and you can play with any sweaty horse!"
"Sir, thank you..."
"hey-hey……"
While Li Sheng was riding a horse and admiring the spring and summer scenery of the Tang Dynasty, he poured chicken soup into the two maids.
At this moment, suddenly there was a rapid sound of horse hooves and whistling in the forest.
The two maids were still in a daze when they saw several strong men on horseback, wearing leather armor and short hair, surrounding them.
"For those from the Southern Dynasty, put down your belongings and leave the little girl behind. If you are wise, get out of here!"
Mian'er Ying'er suddenly screamed in fright.
Turks!
However, Li Sheng just smiled and calmly took down the bow and arrow from his back.
"Then if I don't get out, can you kowtow to me?"
…
Several Turks obviously did not expect that Li Sheng could be so calm and arrogant!
For a moment, I didn't even react.
"Brother, what does this southerner say?"
"He...he asked us to kowtow to him!"
"What?!"
Several Turks looked at Li Sheng angrily and drew their machetes on the spot.
Yes, it is true that the opponent has a bow and arrow in his hand.
But the skills of the Han people in the Southern Dynasties with bows and horses were never as good as those who grew up on horses.
Therefore, he was not afraid at all. He straightened up his scimitar and was about to charge forward.
Li Sheng could only hehe, he thought that this mythical archery skill would be useless now that he was no longer an Orion, but now it seems that it is still somewhat useful.
But right now.
Suddenly a loud shout came from deep in the forest.
"Hey! You Turkic barbarian, let me go!"
Immediately afterwards, a burly man riding a tall horse came out of the depths of the forest like a black whirlwind.
Li Sheng did not put down his bow and arrow, preparing to wait and see for support, but this giant man was obviously very skilled in martial arts. With just a few charges of his war horse, he killed all five or six Turks!
Then he put away the big ax and turned to look at Li Sheng.
He cupped his fists on the spot and said, "Young master is well and well! My surname is Chen, and I live in Chang'an! I watched your musical talent and poetry that day, and I admire you very much! I also heard that your master knows everything about stars, geography, literature, Tao, and military strategy, so I came here to pay my respects!"
…
"The surname is Chen? This ax..."
Li Sheng tried his best to think about it, but he couldn't remember what the Xuanhua Banxiu in the TV series Miles Yaojin looked like.
This guy was really good at martial arts, and he was from Chang'an. Li Sheng couldn't help but immediately think of the legendary Cheng Yaojin!
However, the xuanhua axes in movies and TV dramas are all props and cannot be made accurately, not to mention that the person's surname is Chen, not Cheng.
Besides, Li Sheng is very realist.
Even if he travels through time, he is just an ordinary person. How can he meet a celebrity like Cheng Yaojin so easily?
So he quickly put aside his thoughts, smiled and cupped his hands:
"Old Chen, right? When I saw Brother Chen at the piano performance, I felt that Brother Chen was extraordinary..."
"Well, Master, Lao Chen just took a look from a distance that day..."
Li Sheng was stunned and smiled awkwardly, but...since he met the guests, he naturally had to entertain them.
"Well, maybe you admitted your mistake, haha...Brother Chen, are you tired after coming all the way?"
What I mean by this is that if you just came to see the idols, then when you’re done, go away by yourself and don’t delay the young master’s spring outing with his maid.
But what was unexpected was that Old Chen smiled kindly and said, "Young Master, you are joking, how long is this distance? To be honest, Old Chen also serves in the Xuanjia Army on weekdays, so he still knows how to control a horse."
.When I saw the young master today and looked at how he was dressed, I guess he is also a martial arts practitioner. Why don’t we hunt here and make friends with martial arts?"
Li Sheng was secretly stunned. This ancient man was so bad at everything he did.
This is what Lao Li is like, and so is Lao Chen.
But we were out hunting today anyway, so there was nothing wrong with forming a team.
He immediately smiled and said, "Isn't that great, Lao Chen, please!"
"Sir, please!"
The true identity of this old Chen is of course Cheng Yaojin.
Although Cheng Yaojin has a reckless personality, he is not that kind of brainless, and he can also watch people's words. It seems that Du Ruhui and others are very secretive about this person's identity, so they are smart enough not to reveal his true identity.
"Sir, the secret weapons you and Lao Li mentioned earlier... are they all true?"
"This thing is called a grenade. Is it really that powerful?"
