Papermaking should be the highest in Northern Qi, of course, this is also the secret of Northern Qi. The people of Northern Qi are good at making paper. Most of the best papers in the world come from Northern Qi, especially those tribute papers, which are thin, soft and easy to use.

But if they arrive in the Great Zhou Dynasty, the cost will be high, so paper in the Great Zhou Dynasty is actually quite expensive. If they really have papermaking skills, then they can be self-sufficient in the future and save a lot of money, and even more so that poor students can have paper.

This time, the Northern Qi Dynasty really released a lot of blood for Xuecai. In fact, have they not released enough blood on Dazhou?

The battle at Chending Mountain has caused them to lose a city. Now the city is still in the hands of Dazhou. The city is not just as simple as a city, but also a large area of ​​iron ore is distributed among them.

Anyway, no matter how much blood is, it will be released. Now Northern Qi belongs to the Great Zhou tribute country, so it can make the other two countries more afraid. If there are troops sent and wars are fought, it is hard to say that they will win or lose.

Emperor Wenyuan was very moved by the exchange of Northern Qi this time. Even if Northern Qi left a few tricks, it would be harmless. As long as the Great Zhou could make better papers on its own, so what if they hid something? This is a big deal for improving people's livelihood.

The satisfaction in Emperor Wenyuan's eyes also made Northern Qi feel relieved. It seems that the use of papermaking this time was right. Of course, as Emperor Wenyuan expected, they could not really hand over their most valuable things to others. But even so, even if they only gave 30%, it would be enough for the Great Zhou Dynasty to use, and they would have to reduce the paper to at least half of the price.

Of course, there is no fear of regret between countries.

What is the gift, what is it, what is it promised, and what is it?

The eunuch took out another copy, which was something that Bai Chu wanted to exchange.

What Bai Chu gave is the purification of fine salt. As we all know, Bai Chu's salt is the most refined, and the salt that is actually mined, whether it is official or private salt, is too much magazine quality, and the fineness of Bai Chu is missing.

So what Bai Chu gave is considered to be a change in people's livelihood. The two are just as good as each other, so it is impossible to say who will suffer a loss?

The last one to recite was Cang Tao.

Cangtao is the strongest national strength, mainly because Cangtao has strong soldiers and a wide range of generals, and is rich in many places, so Cangtao's people's livelihood is much stronger than other countries, including the Great Zhou Dynasty. I just don't know what Cangtao wants to use to exchange for the planting method of this snow vegetable and seeds.

At this time, the eunuch's sharp voice had already sounded.

"Cangtao is willing to use silk making techniques to exchange for the snow vegetable planting technique and good varieties of Dazhou."

Shen Qingci pulled Luo Hengli's sleeves, "If I remember correctly, their iron melting technique should be the highest, and their iron tools are famous all over the world, and there are no weapons in thousands."

Therefore, in terms of the ratio of the army, these alone are much stronger than other countries.

Zhuge crossbows have appeared in other countries now. As for the Eight Niu Crossbows, only the Great Zhou Dynasty has it, because the Eight Niu Crossbows were obtained by Shen Qingci. She didn't know whether it would appear in other places. But for now, it seems that only the Great Zhou Dynasty has Eight Niu Crossbows.

The existence of the Eight Niu Crossbow is also the most powerful confidence of the Great Zhou.
