let go of that priestess

But this time, after not watching for long, Ji Cheng suddenly raised his brows:

"Northeast of the Montenegro Plain, the place where demons are sealed!?"

"Uh......"

Jiang Hongdou looked up at Ji Cheng and blinked: "Husband, you won't believe it...

Based on my previous experience as a high priest, the so-called demon-sealed land described by the Alliance of Three Clans is nothing more than a bad landform.

Before they squeezed into the Black Mountain Plain and were stuck at the entrance of the plain, there was a big river on one side and an insurmountable barren land on the other. They could only choose to confront the bear and deer tribe head-on, which probably meant this.

Although the description is a bit scary, it says that there is no living thing, not a single grass or tree in the sealed demon land, but it means a barren land..."

"I know that sealing the demon is false, but this description is not only barren and there is no living thing, it also says that the land is brownish yellow, and the land near the center is reddish, and in the center there is a devil's eye that sheds tears of the devil all the year round, exuding resentment. pungent smell...

This is a spring!The devil's eye is the ground spring!

The nearby brownish-yellow to reddish-brown ground should be formed by the underground minerals brought out by the spring, combined with the pungent smell, this is... sulfur! ?

The sulfur accumulated over the years has resulted in no vegetation, no living things, and silence, which is very reasonable! "

"What!?" Jiang Hongdou was taken aback when he heard this, and finally understood why Ji Cheng took it so seriously.

Could this be the sulfur that their prospecting team has not discovered so far, and the town is in urgent need of? ?

"Husband, are you sure!?"

"Not entirely sure, it just feels a lot like it."

Ji Cheng carefully read the description of the land where the demons are sealed several times, and said:

"This site is very much like a sedimentary sulfur deposit formed by biochemical processes.

It is formed by bacterial reduction of sulfate in a closed environment, often interbedded with limestone or gypsum layers.

In addition, in the lower part of the oxidation zone of the sulfide deposit, there may be sulfur formed by the oxidation and decomposition of metal sulfide, that is, there may be pyrite! "

"Ah! Hurry up and notify the prospecting team!"

After waiting for so long, although Jiang Hongdou kept advising Ji Cheng not to rush and take his time, but at this time, her heart beat faster.

"Anyway, we must ask the prospecting team to bring back some samples, and you can identify them!

If it is really sulfur, rubber vulcanization technology and smokeless gunpowder technology can be advanced again! "

"Yeah." Ji Cheng took a deep breath and said, "Let the communication room expedite the communication tonight."

Chapter 262 Worthy of being an adult (Xie Yexian rewards 1w points~)

The night wind blew gently, and the grass swayed from side to side, as if unable to hold back the drowsiness, he kept nodding his head.

But the next moment, the wind direction changed suddenly, and the silent night was suddenly awakened.

The grass neatly broke through the middle, and four paw prints were left on the slightly damp ground at the same time.

A muscular moonlight wolf messenger rushed forward under the moonlight like a sharp arrow galloping close to the ground, and the blue wolf eyes regarded the night as nothing.

In the era when the only means of lighting were torches, if communication was needed at night, Moonlight Wolf was Dongxu Town's first choice.

The running speed exceeds 65 kilometers per hour, and the endurance is much better than that of ordinary wolves.

Along Tongxu Road, half an hour later, he smelled the breath of other moonlight wolves about 32 kilometers away from the town.

Each prospecting team is equipped with a moonlight wolf to assist in the exploration of the magic element stone, and this should be the closest prospecting team to the town.

The messenger Moonlight Wolf stopped abruptly, sniffed a few more times to confirm its position, then raised its head, looked up at the moon, and let out a wolf howl.

"Aww!—"

The howling of wolves spread far away, and it didn't take long for the response from the same race.

Ten minutes later, he sniffed the scent, guided by the howls of his fellow wolves, and went straight forward, and soon found the 47th prospecting team that was camping for a rest.

The urgent letter was sent to the captain who heard the sound, and the content of the letter was in the form of half text and half picture.

With the light of the bonfire, the team leader who had been specially trained in this area quickly understood the meaning of the letter, and only after signing the money did he discover that the letter was transmitted directly by the adults himself, not from the council hall, nor through the council Hall transfer.

The captain's face turned serious, and after confirming the location described in the letter again, he took out a stack of filter masks made of cloth leather from the envelope of the messenger Moonlight Wolf, and took out a piece of engraved 47 from his coat pocket. Put the wooden block of receipt with the words "team" into the letter bag, indicating that the letter has been received.

The messenger Moonlight Wolf nodded the wolf's head to confirm that the process was correct, he howled again, then turned and ran back towards the town.

The next day, just after dawn, the captain woke up the team members one by one, explained the new mission, the steam car started, and quickly drove towards the place where the demons were sealed.

Three days later, they came to the front line of the Ministry of Military Affairs and explained the mission situation again. The Ministry of Military Affairs cooperated and helped them replenish fuel and food for the 47 prospecting teams, and escorted them across the entire Montenegro plain, exited from the west exit, and then continued to the northeast. go ahead.

A week later, Dongxu Town, Shenju.

Ji Cheng got the five sample stones sent by the prospecting team at the fastest speed, and after only one glance, he looked overjoyed.

With one move of his hand, his imperial sword turned into a blue light and flew to the largest office in the east of the Council Hall.

"red beans!"

"Huh? Oh! Is there news?"

"Well, it has been confirmed, it is indeed sulfur!"

"Great!"

Jiang Hongdou's eyes lit up, and he put aside other documents on the table:

"I'll arrange it now! Tongxu Road will be extended and built until the sulfur deposit, and a factory will be built!

The military sent troops to protect and guard against the tribes moving eastward! "

......

......

In a month's time, the Alliance of Three Clans took the initiative to learn and integrate, and was finally roughly ready.

Today, the three patriarchs led the sacrificial team and went to the council hall together with the family inheritance records to submit an application to formally join Dongxu Town.

The people of the ethnic group have popularized basic knowledge and the new laws and regulations of Dongxu Town, and they can already participate in work normally. They want to pay back the first installment of the migration subsidy food as soon as possible.

But on this point, the Council informed them that they can directly exempt 20% of the original total score fee.

Puzzled and asked the reason, the answer was that the information provided by the Tri-Clan Alliance had made great contributions.

Made a contribution?

What credit can waive the 20% total fee...

This is a huge contribution!

The three patriarchs looked at each other, and they were all overjoyed. Then Mu Shui stepped forward and saluted the reception staff of the council hall:

"It's convenient to ask, what kind of intelligence has made a contribution?"

"Well, it's about sealing the land of demons. My lord thinks that land is very valuable and attaches great importance to it."

"Eh?......"

Seal the land of demons! ?

The three patriarchs were dumbfounded when they heard the words.

The information submitted at the beginning was just a description of the situation in the west as required, and the whole process of their eastward migration.

At that time, the Alliance of Three Clans was blocked by a river and a land of sealed demons where there was no grass, no living things, and no way for the tribes to migrate.

Among them, the latter was only mentioned in passing, but instead made a contribution?

Furthermore, the adults actually said that the land is very valuable and attaches great importance to it?Isn't it a utterly barren place?

Well... maybe, it's time to think about it from another angle.

Mu Shui, Sa Guang, and Sai Hui all thought of something at the same time, their eyes couldn't help but a sense of admiration rose in their hearts.

My lord, it should be a duel with that fallen god!

That's right, this is the demeanor an adult should have!As expected of an adult!

......

In the private backyard behind Shenju, the image of Ji Cheng at this time may not match the stalwart and tall imagined by the Alliance of Three Clans...

He was burying his head on the laboratory table while writing and drawing, and couldn't help but giggle:

"Okay! Okay! The conditions are all met! The technology line is on!

The nitric acid produced by the bat caves in Kanchen Forest + ignited sulfur, the reaction produces sulfur dioxide, and if there is no lead room, then inherit the red spirit, burn the matching porcelain cylinder, and use the cylinder tower method to make sulfuric acid.

With sulfuric acid, it is possible to mix acid with nitric acid. The acid solution mixed in proportion is stirred with a glass rod made by a glass factory, covered with a ground glass cover and cooled to room temperature.

Then use the paper produced in the town or freshly harvested cotton as absorbent cotton, soak it in the acid solution, and react at room temperature for 20 minutes. After the nitrification treatment, take it out and clean it for stabilization treatment.

Well, the sodium carbonate needed for stabilization, I think...

Oh yes!It can be made by using the plants that grow in the saline-alkali land next to the salt lake by burning plant ash!

good!That way, you end up with nitrocellulose!Smokeless gunpowder!Coupled with the fixed loading metal shell case, it will open a new era of firearms! ! !

Hmm, calm down...there's still the matter of how the nitrocellulose is preserved.

Digging an underground ice cellar?It should work.

After nitrocellulose is bottled, it is placed in an ice cellar, but the temperature should not be too low to cause the fibers to break.

At that time, make specific adjustments. If the temperature is well controlled, it should be able to be stored for several years, enough!

......"

Ji Cheng muttered to himself and sorted out his thoughts, holding a charcoal pen in his hand and slowly wrote out all the research and development process from beginning to end.

After finishing writing, he went back and checked it several times, annotating some specific details so as not to forget.

Yes, after staying in the primitive world for several years, Ji Cheng found that the knowledge in his mind had begun to be forgotten.

It turned out that when he was at Blue Star, there would be regular and strict assessments, and no one forced him to memorize these things when he got here, instead he had to review them from time to time...

"Hey......"

The excitement gradually calmed down, Ji Cheng recalled the past scenes, and couldn't help but sigh softly.

In the past, it was troublesome to memorize so much miscellaneous knowledge, but now it seems that the General Administration of Traveling is really responsible for him, the time machine pilot.

The response to extreme unexpected situations is not sloppy at all.

Forget it...so much for the memories.

Ji Cheng lowered his head and rubbed his forehead, changed to a new piece of paper, thought for a while, and wrote the first line on it—the heat vulcanization of rubber vulcanization.

Chapter 263 New Inheritance Record

The emergence of sulfur has broken the technical limitations of Dongxu Town.

After pondering for a few days, Ji Cheng perfected two process flow charts.

Among them, the smokeless gunpowder will be kept strictly confidential. Like black gunpowder, the process steps are divided and disrupted, and the division of labor is done in detail.

In addition, regarding the location selection of various industrial chemical plants required for the production of smokeless gunpowder, or the location selection of a military factory that combines them, it needs to be carefully considered——

It is good for textile and manufacturing factories to be located near Dongxu Town, but it is better for factories related to chemical industry to be far away from the town.
