Chen Jing was in the room, looking at the book in his hand.

Before coming to this world, he prepared several books such as "Heavenly Creations", thinking that if he wanted to participate in the world hegemony, it was always necessary to climb the science and technology tree.

But after coming here, he found that the Tang Shuanglong Legend is an overhead world, with a construction level as high as a city wall more than ten zhang high, and other technical depths are similar, such as the blast furnace of the Dongming faction, which is actually coal-burning. The books I brought with me were not enough to even read "Heavenly Creations" in front of this ancient black technology.

He once thought about establishing a modern industrial system, even at the level of the nineteenth century, but he did not study engineering, and even if he studied engineering, he could not climb the science and technology tree alone. And at that time, practicing martial arts for self-protection was much more important than climbing the science and technology tree, so this plan had to be temporarily shelved.

Now that he has won the Dongming faction, occupies the Ryukyus, and has a base area, in order to build, the matter of the technology tree is also on the agenda.

After the Dongming faction implemented the new style, Chen Jing gained a lot of world sources.

He began to think about summoning an ancient Chinese scientist who was suitable for the current situation. He couldn't think about other countries for the time being, for a simple reason: he couldn't communicate with them. Even if he had studied English for many years, even if those ancient scientists knew English, it was only ancient English, and he couldn't understand it at all. Summoning Chinese scientists can at least communicate in writing.

There are two candidates, one is Song Yingxing, the compiler of "Tiangong Kaiwu", and the other is Mao Yuanyi, the compiler of "Wubei Zhi".

Originally, he was more interested in Song Yingxing, but he didn't expect that there was no such person in the battle flag.

The people who exist in the battle flag are all war-related or battle-related figures, and there is not a single pure scientist. Chen Jing, who discovered this, searched for people he knew, and found that neither Newton, Einstein, Planck, Bohr, nor even Oppenheimer, who made the first atomic bomb, did not exist.

Only those who have unfinished business in the affairs of war will sleep in the battle flag. And Newton, none of them had expectations for war.

He could only choose Mao Yuanyi. Born in the late Ming Dynasty, he not only had a good understanding of science and technology, but also as a leading general, he did not let go of the situation of the lax military equipment at the end of the Ming Dynasty until his death.

Summoning Mao Yuanyi, Chen Jing only chanted two lines of poetry: Sending cold stars to Quan, I recommend Xuanyuan with my blood. Then he asked, are you willing to let the Central Plains no longer be infested by the Tartars?

Mao Yuanyi responded to the call.

Mao Yuanyi, who appeared in front of Chen Jing, was wearing a common mountain armor in the Ming Dynasty, and he looked very powerful.

"General Mao, this world is not as ordinary as you were when you were alive, are you prepared?" As soon as he saw Mao Yuanyi, Chen Jing said loudly.

"The battle flag is mysterious, and everything has been told to Yu." Mao Yuanyi said in a deep voice.

"No matter how difficult it is, I will do my best to help my Central Plains from being invaded by the Tartars."

……

"Boom!" Shan Meixian looked at the soaring flames and closed her mouth in surprise.

"Mr. Chen, this is something that changed the war. I'm afraid that the arms business that I used to rely on for a living will no longer be able to continue. "Shan Meixian said.

Compared with Shan Meixian's exclamation, Chen Jing was very calm.

It's just a small explosive bag made of black powder from magazines.

In the world of Datang Shuanglong, this kind of power cannot determine the direction of the war. If you want to blow up the body protection true qi of the innate master, the charge of this black powder containing impurities needs a full kilogram. With the current preparation capacity of the Dongming faction, it can only make one kilogram of this black powder in a month.

And you have to consider whether you can hit it or not.

The explosives pack is a weapon for attacking fortifications, and it is used to fight martial arts masters like using a cannon to fight mosquitoes.

Although Mao Yuanyi was not a real technician, he also knew that he needed to use this black powder to propel the bullet. This is the real means to kill martial arts masters.

And it must be a conical bullet with sufficient penetration.

Of course, there is a manufacturing method for bird guns in "Heavenly Creations", but the power of bird guns cannot be used to fight martial arts masters, even ordinary heavy armor soldiers can't deal with them.

For penetration and accuracy, Chen Jing needed a rifled gun.

"Mr. Chen, I need a professional craftsman." This is the most sincere request of Mao Yuanyi, who was appointed by Chen Jing to conduct research and development.

In this regard, Chen Jing could only smile bitterly.

The craftsmen of the Dongming faction were all swordsmen, and they didn't know anything about making gun barrels. But Chen Jing has no other talent to find.

Without a qualified barrel, a powder gun simply does not make sense.

"General Mao, please figure it out for yourself." Chen Jing could only answer like this.

I need to go out and about.

Lu Miaozi of Pegasus Ranch. He could only think of this one person who might know how to make a gun barrel in this era.

However, can he really leave the Dongming faction?

Everything here is just getting on track, whether it's new learning, technology trees, including new fashions.

Whether Shan Meixian and Shan Wanjing can accept these new things, although they seem to like it very much, Chen Jing can't be sure if this is whether he is here, and they can't resist the compromise that it brings.

If she left, Shan Meixian would make a move, and none of the people on the island would be able to stop her attack. Even Wei Zhenzhen, the number one general under him, can't do it.

Shan Meixian, whose mood has been partially restored, has a straight track to catch up with the grandmaster. Even Chen Jing, who is now making progress in martial arts, can only be suppressed by relying on the incomparably powerful skills of the wedding dress.

"Knock knock!" At night, Chen Jing, who was undecided, suddenly heard a knock on the door.

"Who?" He asked.

"Mr. Chen, it's me." A familiar, soft voice came.

"It turned out to be Mrs. Shan." Chen Jing opened the door and greeted.

Shan Meixian was dressed in black, and her expression was more solemn.

Looking at it like this, Chen Jing knew that Shan Meixian was afraid of something.

Is this here for a showdown? Chen Jing thought about it, welcomed Shan Meixian into the house, and closed the door.

The two of them talked secretly late at night, and it was not easy for others to be seen.

Gossip may not matter, if there are "smart people" who think that the two major forces on the island, old and new, are going to have a dispute, it will be troublesome.

"Mrs. Shan, I don't know what the important thing is to come here late at night?" Chen Jing asked.

"Mr. Chen, I won't say anything superfluous. I'm here to reassure Mr. Chen, the island is guarded by me and Commander Wei, and I won't let you down. "Shan Meixian said.

Chen Jing was noncommittal. Shan Meixian's statement is meaningless. It was a matter of success or failure, and he simply could not believe in such empty guarantees.

As if seeing Chen Jing's thoughts, Shan Meixian said again: "When Mr. Chen goes to the Central Plains, I hope to let Wanjing follow. ”

This is, exchange of hostages? Chen Jing glanced at Shan Meixian in some surprise.

How could she believe in herself?

What he saw in Shan Meixian's eyes was only determination.

She can do this, and I don't need to doubt it anymore. Chen Jing made up his mind.

There is no suspicion in employing people, and there is no need for suspicious people. Since Shan Meixian expressed her submission and was willing to let Shan Wanjing be a hostage, there was no need for her not to believe her.

Shan Wanjing is definitely the most important person in Shan Meixian. can let her follow him, and he has no reason not to believe her.

"Madam, Chen will bring Princess Wanjing back to Ryukyu safely." Chen Jing finally expressed his position.
