Su Dawei finally remembered the ice making incident.

However, when he told Gao Dalong about something like nitrogen, he was given a roll of his eyes.

Su Dawei himself had already given the teacher how to make saltpeter.

This problem did not stump him in the end.

He won't, someone will.

I came to Yuan Shoucheng and Taoist priests to refine alchemy, and should be familiar with this kind of nitrogen production.

If you want, Su Dawei can even provide a prescription for **, but he just doesn't know the specific proportion.

In the end, both Taoist priests, Yuan Shoucheng and Ye Fashan, agreed to have invested in Su Dawei's ice making business.

Technology-based stakes.

When Yuchi Baolin later learned about this, she was very angry and even scolded Su Dawei for being heartless and not taking care of her relatives if she had good things.

Su Dawei said that he didn't know how to refine alchemy and make salt, but he was scolded by Yuchi Baolin.

He said that Aye Yuchi Gong was bored at home, and he began to think about elixirs recently, and also learned to learn red pine nuts and swallowed jade essence.

It scared Su Dawei very much.

I'm afraid that he will make this thing come out of Wushi. It's very pleasant to eat it, and it's going to be fatal if you eat too much.

I have to find an opportunity to persuade Yuchi Gong...

Time is coming to early May.

Su Dawei finally raised his head and breathed a little from the busyness.

Because Su Dingfang returned from conquering Liaodong.

From the expedition to the return of Chang'an, it took less than four months to fight. Apart from the journey, it didn't take long to actually use it for battle.

In contrast, the results of the battle are not ideal.

To the outside world, Goguryeo was convinced and promised not to bully Silla.

Actually...

After crossing the Liao River, more than a thousand Goguryeo people were killed and several villages were burned.

That's all.

With this battle, Su Dingfang was awarded the title of General of Youtun Guard and was granted the title of Duke of Linqing County.

However, Su Dingfang himself was not satisfied with this result.

Many people are not satisfied.

However, it is difficult for North Korea and China to achieve a good record with many constraints.

"Ami, is Ami here?"

Su Dawei had just returned home and didn't even get a breath when he saw a familiar person walking into his courtyard.

When I looked up, it was Su Qingyue, which had not been seen for many days.

"Lion, why are you here?"

Su Dawei was overjoyed.

Take the initiative to stand up and meet him.

Last time Su Dingfang went to Goguryeo, he persuaded him and finally kidnapped the lion out, hoping that he would inherit his mantle and expand territory for the Tang Dynasty in the future.

"Don't mention it."
