Inside the village.

Li Sheng looked at the bright transparent liquid in the beaker, and his whole body seemed to be exhausted.

"It's finally done!"

This liquid is nothing else, but...sulfuric acid!

Sulfuric acid is very scary, and in the news of Li Sheng’s previous life, he often appears as a tool for committing crimes.

But in fact, in industry, this is one of the most important raw materials, and it can even be removed. This is the most important material.

With sulfuric acid, various chemical materials can be prepared through redox, various reactions...

Of course, Li Sheng had made this thing before, but the purity was too low.

The standard industrial concentrated sulfuric acid is 98%, while the one he produces is basically less than 50%.

However, after a period of hard work, time gradually entered summer.

By this time, Li Sheng finally prepared standard concentrated sulfuric acid!

Not to mention this thing, it is a great choice for making glass.

Then put perfume in Zichengzhai-

Li Sheng could guess what the scene was.

Breaking out!

This is just a preliminary application.

In the subsequent various... chemical industry, sulfuric acid is not used, and sulfuric acid is the most important thing.

And with sulfuric acid, nitric acid can be made.

With nitric acid, hehe...

Li Sheng can make real fried yao without using a beggar version of fake fried yao like compressed black fire yao to deal with the problem.

Moreover, nitric fertilizer is also a good thing.

Highlight an advanced one!

These things were done last night, but Li Shengda was excited and wanted to come and have a look in the morning.

This is like having high scores in the college entrance examination and saving money to buy a new car. You have to look at it every day to feel at ease.

At this time, Mian'er Ying'er was already urging her outside.

Li Sheng responded, "Come soon!"

At this time, Li Sheng was wearing a black outfit, just like he had gone to Chang'an to attend a piano competition before.

As for the itinerary on this day, it was not to go to Chang'an, but Li Sheng agreed to Mian'er Ying'er that the first day of April would take a holiday and everyone went out to hunt and build a team together.

Mian'er Ying'er had never heard of the novel word "Team Construction", but the young master still knew that it was going to take them out to play.

So I got up early in the morning and dressed up early and got excited.

Li Sheng wanted to recall the excitement of last night, and the two maids had to dress up. The early morning was wasted until ten o'clock before setting off...

Fortunately, the weather is good!

At the turn of spring and summer, the sun is as bright as a painting.

Li Sheng took two maids, bathed in the spring, and rode his horse outside Youzhou City, which was so comfortable...

"You two work hard and learn more. Now we can only ride short horses. In the future, you will learn a skill and play with any sweat and blood horses at will!"

"Young Master, thank you..."

"hey-hey……"

While riding a horse riding on a horseback riding, Li Sheng enjoyed the scenery of the Tang Dynasty in spring and summer, while pouring chicken soup into the two maids.

At this moment, suddenly there was a burst of rapid horse hooves and howling sounds in the forest.

The two maids were still in a daze, and saw a few strong men riding horses, leather armor and hair surrounded them.

"Of the Southern Dynasty, let go of your property, the little girl stays, and those who know the truth quickly get out!"

Mian'er Ying'er suddenly screamed in fear.

Turkic people!

However, Li Sheng just smiled slightly and calmly took off the bow and arrow behind him.

"Then if I don't get out, can you kowtow to me?"

...

Several Turkic people obviously didn't expect that Li Sheng was so calm and arrogant!

For a moment, I didn't react a little.

"Brother, what did this southern man say?"

"He...he asked us to kowtow to him!"

"What?!"

Several Turkic people glared at Li Sheng and drew out a scimitar on the spot.

Yes, it is true that the other party has a bow and arrow in his hand.

However, the Han people in the Southern Dynasty had never been as good as those who grew up on horseback.

Therefore, I was not afraid at all, and I was about to rush up when I erected the scimitar.

Li Sheng had no choice but to hehe, and he thought that if he was not a hunter, this mythical shooting technique would be useless. It seems to be a bit useful now.

But at this moment.

Suddenly a loud shout came from the depths of the forest.

"Ha! Then Turkic barbarian, let this young master go!"

Immediately afterwards, a burly giant man rode a tall horse and rushed out from the depths of the forest like a black whirlwind.

Li Sheng did not put down his bow and arrow, and was about to wait and see for support, but the giant man was obviously very skilled in martial arts. He charged forward several war horses and killed all five or six Turks on the horse!

Then he put away his big axe and turned to look at Li Sheng.

He clasped his fists on the spot, "Young Master, don't be fine! My surname is Chen, and I live in Chang'an! I watched the young master's piano and poetry skills that day, and I admire him very much! I also heard that the young master Xingchen knew everything from geography, literature, martial arts and martial arts, so I came to pay my respects and look up to you!"

...

"Submitted to Chen? This axe..."

Li Sheng thought about it hard, but he didn't remember what the Xuanhua Axe looked like in the TV series Mid-day TV series.

This guy is really good at martial arts. He came from Chang'an again. Li Sheng couldn't help but think of the legendary Cheng Yaojin immediately!

However, the Xuanhua Axe in the film and television dramas are all props and cannot be done accurately, not to mention that the other person’s surname is Chen but not Cheng.

Besides, Li Sheng is a very realistic person.

Even if you travel through time, you are just an ordinary person. How could you encounter a star like Cheng Yaojin so easily?

So I quickly put aside my thoughts and bowed with a smile:

"Old Chen, right? When I saw Brother Chen at the piano meeting, I thought Brother Chen was extraordinary..."

"Uh, young master, Old Chen just looked at him from a distance that day..."

Li Sheng was stunned and smiled awkwardly, but... since he met a guest, he naturally had to entertain him.

"Uh, maybe I admit my mistake, haha... Brother Chen is tired from a long distance, are you?"

What this means is that if you just come to see your idol, then after watching it, hurry up and leave yourself, don’t delay my maid’s spring outing.

But what was unexpected was that the old Chen smiled kindly, "Young Master is joking, how long is it? To be honest, the old Chen also plays in the Xuanjia Army on weekdays, and he still knows the horse-controlling technique. Today, when I see the young master, I look at the young master's dress, I think I am a martial artist. Why don't we hunt here and make friends with martial arts?"

Li Sheng was secretly shocked. These ancient people were really awesome in their work.

This is true for Lao Li, and this is true for Lao Chen.

But I was going to hunt today, so it was nothing to form a teammate.

He immediately smiled, "That's not very good, Lao Chen, please!"

"Young Master, please!"

The true identity of this old Chen is naturally Cheng Yaojin.

Although Cheng Yaojin has a reckless personality, he is not the kind of brainless person, and he can also observe his words and expressions. Seeing that Du Ruhui and his group are all secretive about this person's identity, they are also clever and do not reveal their true identity.

"Young Master, the secret weapons you and Lao Li and the others mentioned before, are all true?"
