And the rest of the Yelang clan who saw them off on the side were also full of reluctance. Jiang Chao's departure this time, I don't know when I will be able to come back.

Moreover, everyone also heard that the court seemed to know that Jiang Chao had a private army, and everyone knew that the emperor would definitely not let Jiang Chao go.

I don't know if Jiang Chao can protect himself from the emperor.

But since Jiang Chao was not worried, they also felt that Jiang Chao must have his own plans.

Everyone said something of concern and sent Jiang Chao onto the big boat.

With the paddle of the ship, the giant ship headed downstream. Jiang Chao waved goodbye to everyone, and looked at Dongliyue, who had been watching him on the shore, feeling a little uncomfortable.

Speaking of which, he has mixed feelings about Dong Liyue, saying that he loves it, but he can't talk about it, and if he doesn't love it, he can't talk about it.

He has a crush on Dong Liyue, coupled with Dong Liyue's fiery emotions, so he can't refuse.

Of course, the main reason is that everything in the Yelang clan needs to leave the moon in the east.

He somewhat took advantage of Dong Liyue, but he slowly poured his emotions into Dong Liyue. Although, emotionally, she is still not as good as Su Xiaoxiao, but she is not much different.

When the dock slowly disappeared from sight, Jiang Chao still saw Dong Liyue standing on the dock and looking at this side from a distance.

Jiang Chao's heart was full of complexity, but a warmth slowly swelled up.

Putting away his sorrows, Jiang Chao watched the giant ship move forward under the power of the pulp, and the speed was very slow. There was a smile in his eyes.

When steam technology matures, merchant ships can also be converted into steamships.

At that time, there will be no need for manpower to propel the giant ship forward.

When Jiang Chao returned to the mountain village, Dongli Ying told Jiang Chao that the emperor's holy decree had arrived. Moreover, it was two days away.

Jiang Chao has been in the Yelang clan for the past few days, so he can't answer the order.

Others did not dare to accept the decree, so they could only arrange the eunuch who sent the decree to wait in Anning County.

The situation in the backing village could not be known to the emperor, so Song Ningxue did not put the eunuch in the backing village.

Liu Chengzhi, who has become a county order, is now the only one who is Song Ningxue and Jiang Chao's life. Tie Ying became the county lieutenant. They can now be said to be Jiang Chao's henchmen.

After the eunuchs sent the holy decree to Anning County, they notified Song Ningxue as soon as possible.

But Jiang Chao was in the Yelang clan at the time, and Song Ningxue knew that Jiang Chao had something to do, so she didn't let anyone disturb Jiang Chao.

Anyway, it's just a holy decree, let him wait a few days, it's nothing. Moreover, Jiang Chao also explained at that time that if there was a holy decree coming, let them wait first.

It is estimated that only Jiang Chao in the entire Great Zhao dares to wait for the holy decree like this.

Jiang Chao did not rush to Anning County to receive the holy decree, but went to Jiang Yun's laboratory first.

At this time, Jiang Yun was studying the smokeless gunpowder that Jiang Chao said. Nitric acid and sulfuric acid are a little more difficult to make.

However, with theoretical support, it is also relatively simple and fast. Recently, Jiang Yun has been researching nitric acid and sulfuric acid.

There are quite a few of the two items, and I'm just waiting to make the final nitrocellulose.

Jiang Chao asked him to find a few assistants who were interested in chemistry. It can be regarded as letting him take in the apprentices himself.

Don't look at Jiang Yun is only fifteen or sixteen years old, but he is not sloppy at all, and he is very serious and cautious.

This is also the reason why Jiang Chao is willing to hand over the elementary chemistry book to him. Chemistry experiments can be dangerous if you are not careful and serious.

Fortunately, Jiang Chao didn't need Jiang Yun to research inventions, he just let Jiang Yun practice.

There is theoretical support, and there are explanations for the dangers. Jiang Yun didn't go wrong.

When Jiang Chao came, he had already developed nitrocellulose, but the stability of nitrocellulose was too poor, so it needed to be dissolved in ether and ethanol, and then stabilizer was added to make a gelatinous substance.

Jiang Yun was a little unsure about the operation of this step, and he didn't dare to take the next step for a while.

After all, he had never done it before, and if it wasn't done properly, it could have caused an explosion.

Several assistants beside him were also full of nervousness. Everyone held their breath.

Jiang Chao also happened to come in, and seeing this scene, he walked in front of Jiang Yun and patted Jiang Yun lightly.

He took what Jiang Yun had in his hand and started his own operation, and he asked Jiang Chao to look at it carefully.

Although dissolving is dangerous, as long as it is done properly, there is no problem. Nitrocellulose has not yet reached the point where it will explode at any time.

Jiang Yun and the others watched Jiang Chao's movements nervously on the side, and when Jiang Chao completed the final operation, everyone breathed a sigh of relief.

However, with Jiang Chao as a guiding light, the next work will be much easier.

But Jiang Chao still repeatedly told Jiang Yun to pay attention to safety.

Jiang Chao was overjoyed at this time, first of all, smokeless gunpowder had been successful. Jiang Yun's efforts during this time were not in vain.

One of the most difficult was the research and preparation of various chemical materials in the early stage of smokeless gunpowder. In particular, the production of ether. It's extremely difficult!

Ethanol is relatively simpler, and nitric acid and sulfuric acid are also relatively simpler.

After all, wine and saltpeter, alum are readily available.

Next, when the technology is mature, it can be mass-produced on a large scale, but it is still difficult to mass-produce in this regard.

Ether could not be mass-produced in the first place, but when the technology matures, it will be easier to make.

Jiang Chao is not in a hurry, at least now is the beginning.

To solve the matter of smokeless gunpowder here, Jiang Chao and Song Ningxue went to Anning County together.

It's time to meet the envoy sent by the emperor, and I don't know what is written in the emperor's decree.

When Jiang Chao arrived at the county seat, Liu Chengzhi and Tie Ying, who got the news, hurriedly greeted him.

The two took Jiang Chao to the back hall of the county office, and they sent someone to invite the father-in-law who passed the decree over.

This father-in-law was still the eunuch who had sent an edict to Jiang Chao in Ningzhou Mansion before.

Seeing Jiang Chao appear, the eunuch's face showed a sense of helplessness, and he also had a slight resentment.

However, thinking that Jiang Chao didn't even give the emperor's face, even if he had fire, he didn't dare to send it. The only way to do this is to take out the decree and read it.

He didn't expect Jiang Chao to kneel down to accept the order, after all, Jiang Chao sat on the main seat with a golden sword, and he didn't even mean to get up.

He has long understood Jiang Chao's arrogance, and he has no nonsense.

Jiang Chao listened to the reading of the holy decree, and the corners of his mouth slowly became a little weird. The emperor was generous, not only letting his children form an army, but even unlimited the size.

However, the emperor's meaning was very simple, Jiang Chao must be able to go to the border pass in the shortest possible time to defend against the Khitans.

In addition, half of the army will be divided, and the emperor will send generals to command. Then, it is to go to the anti-thieves in the territory of Dazhao!
