After Xie Jing left, Yao Qing and Yao Zheng were very puzzled, and asked Yao Yudao: "Yu'er, then Xie Jing robbed the camp, he was an enemy, why did you entertain him with wine and meat?" ”

Yao Yu smiled: "Although Xie Jing doesn't have much ability, he has to break through Jiangling. ”

Hearing this, Yao Qing and Yao Zheng were even more confused.

It was Yao Fan's words next to him that solved the doubts of the two.

"This robbery of the camp was originally supposed to be Wang Xuance's task. But Wang Cheng arranged for Xie Jing to come. Why? Or, Wang Cheng is afraid that Wang Xuance's tail will not be big. deliberately suppressed him. Either way, it was Wang Cheng who was just using the relationship with Wang Xuance, and the two were not harmonious. ”

Yao Qing and Yao Zheng still didn't understand what the use of these was, so Yao Fan continued to explain: "Of course it's useful, in these news, we can know that Wang Xuance and Wang Cheng are not of the same mind. This provides us with a space for the discrepancy meter to operate. If Wang Xuance and Wang Cheng can be separated, then the city will only be broken in an instant. Otherwise, it would be very difficult for us to attack Gangneung City, which is strongly defended. ”

Listening to Yao Fan's words, Yao Qing and Yao Zheng, the two elders, suddenly realized that their feelings were the reason.

Yao Yu also smiled and waved his hand: "Okay, now that the plan has been decided, then, it is time for us to act." Wen continued, find a way to contact Chen Zhong who was hidden in the city, and ask him to arrange someone to investigate the news of Fengyue Tower to find out about Wang Xuance. This time, I will use the minimum cost to break through Gangneung City. ”

Wen Xu agreed, turned around and left.

···

For the next few days, Xie Jing, under Yao Yu's order, took his surrendered soldiers around the city to surrender, and he didn't show up, so he hid far away, fantasizing all day long about his dream of being promoted to become rich after helping Yao Yu take Jiangling City.

During these times, Yao Yu, Lu Bi, and He Xiong woke up one after another.

Ban Rou's medicine is really easy to use, and the three of them are basically the same as before they were poisoned.

Of course, Yao Yu may be almost, with his physical fitness, he still needs support to walk now.

On this day, Yao Yu, with the support of Ban Rou, led Lu Bi Hexiong to the residence where Yao Zheng of the Chinese army was located.

Because of Yao Zheng's status as an old carpenter, Yao Yu arranged for Yao Zhengtong to lead the craftsmen to supervise the construction of siege equipment.

No, when Yao Yu came, Yao Zheng was still busy.

"Third uncle, how are you busy?"

Yao Yu stepped forward and asked happily.

Yao Zheng saw that it was Yao Yu, and immediately got up and patted the sawdust on his hands: "Yu'er, you are here." I've seen all the drawings you gave me before, and all the parts have been made, and the rest can be built as long as they are assembled. ”

When Yao Yu heard this, he followed Yao Zheng's guidance and came to the place where the parts were stacked.

Long before he fell unconscious, he drew a figure of a building car and handed it to Yao Zhengdu.

In the days when he was in a coma, Yao Zheng did not delay the process.

No, when Yao Zheng led Yao Yu to look at the parts everywhere, he didn't forget to praise Yao Yu's brilliant head, such siege equipment can be imagined.

Yao Yu's praise for his third uncle, Yao Yu smiled slightly, noncommittal.

After all, this building car appeared so frequently in the history of his own world, and even the drawings and working methods could be searched on Baidu, and Yao Yu was particularly interested in ancient warfare before he crossed over, can you remember.

"Third uncle, don't worry about the car or something, I suddenly have a gadget to hand over to you, I don't know, can you make this thing?"

Yao Zheng was puzzled, so he looked at Yao Yu curiously.

Yao Yu took out a stack of parchment and spread it out, densely packed with small notes.

Yao Zheng was very puzzled when he saw it, looked at it again and again with the parchment, and asked Yao Yudao, "What is this?" ”

Yao Yu sighed: "This is called papermaking and movable type printing. ”

"Papermaking?"

"Well, it's a very light and dexterous paper, and a hundred sheets are probably only that thick."

As he spoke, Yao Yu compared his fingers to a height of about one centimeter.

Yao Zheng was shocked when he saw it: "Yu'er, you're not kidding, the thinnest sheepskin can't be so light." ”

"So, if this paper is made, it will definitely shock the world. At that time, books will not be like now, and a book will be pulled by an ox cart. Moreover, not only the convenience, but also the cost, it is much cheaper than sheepskin and silk cloth. At that time, reading and reading will no longer be the power of the family. The children of ordinary people, everyone can have books to read and learn words. ”

Yao Zheng was shocked: "This, is this really as powerful as you say?" ”

"Of course, it's just that I've experimented several times, but I can't find the best material to make paper, and I've been busy trying to make things these days, and I don't have time to improve them. Isn't this just that Uncle San is you, I just wondered if you could make it for it. It's okay if it's longer. ”

Yao Zheng first praised it, and then clenched his fists: "Although it's the first time I've heard of it, I'm willing to give it a try." ”

Hearing this, Yao Yu couldn't help but sigh, and pushed Ban Rou away and threw Yao Zheng away: "Third uncle, if you can do it, you will be a great benefactor of the people in the world." When the time comes, the era of gate lord rule will also pass. ”

Yao Zheng was a little stunned by Yao Yu's words, no, his face was slightly red, reserved, and asked Yao Yu what he meant by living printing.

When Yao Yu explained the live printing clearly, Yao Zheng was even more surprised.

He seems to have seen the glorious future of the people from poor backgrounds.

With such thoughts, Yao Zheng did not hesitate, and immediately called the skilled craftsmen in the army to start studying how to make paper.

Live printing is easy to do, but if you are a carpenter, you can understand it if you understand the principle.

And papermaking, that is a technical job, fortunately, there is information given by Yao Yu.

Although Yao Zheng doesn't know how to read, it is not bad to have Yao Yu explain to him.

In this way, Yao Zheng devoted himself to papermaking, and no longer asked about matters in the army, nor did he follow his second brother Yao Qing around.

It was another three days, and three days later, Chen Zhong in the city sent the news.

After many investigations, he unearthed a lot of secrets of Wang Xuance.

Chen Zhong asked a henchman to find Yao Yu and tell him what happened.

Not only did Wang Xuance's secret, but also the news that Xie Jing's family was beheaded in Shicao, which was also sent back.

Xie Jing's matter was put aside, Yao Yu pinched his chin, and pondered about Wang Xuance's matter.

"It turns out that there are such unknown things in Wang Xuance's body. In this way, he and his companions grabbed the credit, all in order to be promoted as soon as possible and pick up their mother? ”

Xiao Zuo nodded with a sigh: "It can be said that anyway, between Wang Cheng and Wang Xuance, there is only mutual use, and there is no loyalty at all." ”

Yao Yu smiled: "In that case, we will have a lot of room to operate." ”
