Hearing Cheng Ruoyu's words, Shen Bin's heart did not fluctuate, some things that should come always have to come, it's not that you don't want him to appear, in the last time he traveled through the time when the four of them got along, Shen Bin didn't feel that kind of warmth, but Shen Bin was always rational.

"Ruoyu, these things, I will send someone to investigate, recently you can study the artillery with Li Jin, but to be on the safe side, these things are carried out secretly, and then you select some people to organize a secret artillery team, everyone signs a secret life and death certificate, and those who violate the order will be beheaded, since we have come to the Tang Dynasty, we will not use their way of fighting to fight, play some new tricks, and give Jieli a little hardship."

Hearing Shen Bin's thoughts, Cheng Ruoyu showed a wicked smile on his face, although he had never made artillery, but he still knew about fireworks salutes, and cooperated with Li Jin, the ancestor of fireworks, Cheng Ruoyu's inner excitement could not be described in words.

"Boss, don't worry, I know what you're worried about."

"Well, find a hidden house, it's best to find an open location, build a separate laboratory, keep the movement as small as possible, and when we leave, we have to do a good job of cleaning up the aftermath."

"Well, Boss."

After Cheng Ruoyu left, Shen Bin and Qin Yu discussed Guo Yi's matter, although he didn't know what was going on with Yang Yiwu, but Shen Bin always felt that things were too strange, and he couldn't find any clues of Yang Yiwu in Dingxiang County, but when he returned to Dingxiang County from the moraine, Yang Yiwu just appeared, and it seemed that he was hiding from people, and he was in a hurry. Now that Jieli is defeated, Yang Yiwu appeared in front of Guo Yi.

"Qin Yu, you can find a reliable person to check Yang Yiwu's whereabouts and information in detail. I always feel that Yang Yiwu's disappearance and appearance seem to have been manipulated by someone, if it was an accident that we met her in Dingxiang County, then it was definitely not an accident that Bai Dao, Moishi and Guo Yi met. ”

"Boss, what suspicions do you have?"

"I don't know, but I have a gut feeling that there is something wrong, since I was a child, my sixth sense is strong, stronger than that of women."

"Okay, I'll send someone to Xiangcha."

A few days later, in a wild place, several houses abruptly rose on the ground, but because the nearby deserted people did not pay attention to the houses that appeared in this wild land, Cheng Ruo looked at the houses in front of him with foolishness, it was good to be an official in ancient times, as long as the order was issued, it was almost effortless to find a place to build a house, and wait for it to be completed.

Cheng Ruoyu glanced at the surrounding environment, dry weeds covered the vast land, the cold wind mixed with the strong smell of the land, in the Tang Dynasty, where the environment was not affected by pollution, you could still feel the smell of dry grass, Cheng Ruoyu took a deep breath. Looking up at the sky, the sun seemed to be very lazy, unwilling to exude too much warmth on his body, Cheng Ruoyu smiled, thinking that he was really a little greedy, it was rare to be in such a good environment, but he still hoped that the winter sun would be warmer. Without the obstruction of haze, Cheng Ruoyu suddenly felt that he was a little happy, and it turned out that the sun in winter could be so bright.

Cheng Ruoyu was in a daze, Li Jin walked out of the room, "My lord, this place is really good", Li Jin's face was full of irrepressible joy, he never thought that he could follow the army, and there are so many houses, although the location is barren, but the love of the chief manager for himself, he is empathetic.

"Have you remembered everything I told you before?" Cheng Ruoyu turned around and didn't think about those who had or didn't.

"My lord, remember, I will study the artillery explained by the adult here with peace of mind, and I will never mention it to outsiders, and I will notify the adult as soon as it is successfully developed." After all, he had rarely seen such a powerful general, and Li Jin seemed a little timid and cowardly.

Cheng Ruoyu directly grabbed Li Jin's shoulder, like a brother, Li Jin's body was obviously so frightened that he almost knelt on the ground, and was pulled by Cheng Ruoyu, "Don't be afraid of whether I'm good or not, you will call me Brother Fool in the future, brother covers you, what are you afraid of?" Cheng Ruoyu patted his chest to show his sincerity.

"More love from adults, Li Jin is ashamed."

Li Jin is not a modern person after all, when he heard Cheng Ruoyu's words, he immediately burst into tears, knelt on the ground with a bend of his knees, kowtowed, and made Cheng Ruoyu very helpless, and hurriedly pulled Li Jin up again, "What are you doing, I will let you call it, you will call it, long-winded, not to punish you." ”

Cheng Ruoyu even took out the way of intimidation, and Li Jin didn't dare not call it, but Li Jin had doubts in his heart, the person in front of him was obviously Li Shichang, the governor of Bingzhou, why did he let him call him "Brother Yu"? He is not a fisherman. But thinking about it, Li Jin never dared to ask directly.

"Let's go, look at our gear."

Cheng Ruoyu pulled into the room, only to see that the originally spacious house was full of materials for making artillery, in order to avoid accidents, the items piled up in each house were also different, and the houses were all made of stones.

Stones, saltpeter, wooden barrels, thick paper pages and other materials are piled up in different houses, Cheng Ruoyu even ordered someone to find a blacksmith to make iron buckets to make artillery, Li Ji glanced at all the raw materials, although he didn't understand what these things were for, but since the adults prepared them, they must be useful.

"We just need to study this artillery this time, and give him a trick when we fight with Jieli, so that he can taste what it means to be a visitor from outside the world, a fairy scattering flowers, hahaha."

Thinking about using these artillery pieces to beat Jieli and not find the southeast and northwest, Cheng Ruoyu couldn't help laughing in his heart, who would have thought that a few of them would use the future way to bully the ancients in this era of cold weapons.

"You first follow what I told you, study here, I still have some things to go back to the governor's mansion, if there is anything you can send someone to inform me, I will arrange someone to take care of your food, clothing, housing and transportation here."

"Yes."

Cheng Ruoyu returned to the General Military Mansion after arranging everything, and when these things are arranged, he must always inform Shen Bin, if Shen Bin has any new ideas, they can communicate in time, and in the next few days, he will be with Li Jin.

Cheng Ruoyu had just returned to the temporary governor's mansion, it was already nightfall, and it was already late at night after Cheng Ruoyu reported everything to Shen Bin, and Cheng Ruoyu did not rush back to Li Jin.

Early the next morning, Li Ji sent someone to deliver a secret letter, because Cheng Ruoyu explained that what they had done should not be mentioned to outsiders. Cheng Ruoyu looked at the envelope in his hand and slapped his head helplessly.

I saw that the envelope was written on it, "Brother Yu personally opened." ”

Shen Bin got up early and saw the envelope in Cheng Ruoyu's hand and laughed directly, thinking that Cheng Ruoyu asked Li Tan to call him Brother Yu, but Li Jin understood it as a fish, but he didn't dare to ask directly, which made such a big joke.

Cheng Ruoyu stepped forward and grabbed Shen Bin's neck and threatened Shen Bin not to laugh anymore.

"Okay, I won't laugh, let's see what's going on with Li Jin, he's our trump card."
