"It's good to be useful, I can help my father, and my sons are also very happy!"

Wei Wuji paused and continued, "I just don't know...... With the sales of soap, can it afford to raise the Northern Army? ”

Emperor Chu shook his head and said, "I originally wanted to rely on soap to support the army.

Just calculated an account, and it doesn't seem to be enough.

But it doesn't matter,

This has already helped me a lot, and it will be enough for me to transfer some more from the granary. ”

Listening to Emperor Chu's words, Wei Wuji thought of something.

If we can make it, we may be able to make up for it.

However, this thing is not easy to make.

He was not completely sure, so he did not mention it to Emperor Chu.

"The retainers retired."

"Hmm."

Wei Wuji returned to Fuzhong.

......

......

Southern Jin Kingdom.

After Li Xian returned, he hurried to see his father.

Li Hong, the emperor of the Southern Jin Dynasty, was born with kind eyebrows and kind eyes, and he loved Li Xian even more.

Li Hong asked: "Xian'er, what did you gain from going to Chu State this time?"

Can you find out clearly, did they establish the Chu State and the Northern Army? ”

"Back to my father, I have already found out clearly..."Li Xian said: "The Northern Army, which belongs to the Chu State Horse and the Great Sima Wei Wuji, is under the command of Cheng Yanjin.

Although Erchen doesn't know where he comes from, he has a good way of training soldiers.

Under his training, the Northern Army already has an elite momentum...

From Wei Wuji, Erchen heard that the formation of the Northern Army was indeed to deal with our Southern Jin Dynasty..."

When Li Xian said this, Li Hong's eyebrows furrowed deeply, and he looked like he was expecting, and said in a deep voice: "Sure enough, it is not what I expected.

In recent years, no country has been willing to support the captives of other countries.

Only the state of Chu set a precedent and was named after 'Zhengbei'.

If they are not here to deal with our Southern Jin Dynasty, who will they deal with? ”

In fact, this question seems very simple to them.

The soldiers of the Northern Army were all formed by the captives of Zhao and Beiqing.

This army, used to fight Zhao and Qing, is somewhat unrealistic.

And the Northern Qi and Chu Guogang formed an alliance, and it was impossible to deal with the Northern Qi.

Then, in addition to these three countries, only the territory of the Southern Jin Dynasty remains, which is linked to the Chu State.

"Ugh..."

Li Hong sighed and sat down slowly: "Our Southern Jin Dynasty is narrow and widowed, and it is difficult to support food and salary, it is not easy to survive among all the countries, how can we face the 100,000 northern army and tens of thousands of elites of the Chu State?"

Xian'er, this time we have a big problem. ”

"Father, according to Erchen, it is not necessarily the case." Li Xiandao.

"Oh? What is Xian'er's idea? Li Hong seemed to have grasped a life-saving straw.

Li Xian said: "When I was in the Chu State, Erchen and the Great Sima Wei Wuji had many secret conversations, and he said that he was willing to help us tide over this difficulty. ”

"Wei Wuji? Is it the concubine of the Chu State? ”

"Yes."

Li Hong shook his head and sighed, "It's unlikely!"

He was a concubine of the State of Chu and was highly used by the Emperor of Chu.

How could you do it, I'm sorry for the state of Chu?

Xian'er, were you deceived by him? ”

Li Xian shook his head and said, "Probably not, father." Because Wei Wuji promised to help, it was also conditional.

He asked us to give thirty million taels.

And then, at the time of the war with us, he was invincible and deliberately stalled for time..."

"What? Thirty million taels?! Li Hong almost fell off the dragon chair.

With the national strength of the Southern Jin Dynasty, it is already the limit to be able to take out 10 million taels.

How can you get 30 million?

"You promised?"

Erchen knew that Nanjin couldn't afford to pay this account, so he didn't agree. After discussing with Wei Wuji for many days, he refused to budge, and his sons came back to plead with their father. ”

Li Hong rolled his eyes and snorted: "This is willing to help us, it's obviously difficult." ”

"This matter is also a great risk for Wei Wuji, and it is reasonable for him to want more benefits."

Li Xian said, "Erchen thinks that if he can really help me in the Southern Jin Dynasty, it would be a solution." ”

"But we can't come up with such a large sum of money..."

"Father, have you forgotten that we just bought soap worth three million taels of silver from the Chu State, and the sales of this thing in the Chu State are very good, and I must not worry about not being able to sell it in my Southern Jin Dynasty."

Li Xian continued, "When we complete the transaction, we will definitely make a lot of money. ”

Li Hong still has doubts about soap.

He said: "Soap is not a necessity of life, can it really be sold so well? ”

"What Erchen has seen with his own eyes, the supply exceeds demand!"

"In that case, you can take care of the soap matter." Li Hongdao.

"Father, I'm afraid my sons don't have time to deal with this matter.

Wei Wuji has not yet agreed to help, and our Southern Jin Dynasty is still at a critical juncture.

If you want to survive this crisis, the only way is to unite all countries to resist Chu together.

Erchen wants to go to Zhao and Beiqing, but I don't know what his father wants? ”

Li Hong pondered for a long time, nodded and said, "What Xian'er said is extremely true, instead of waiting for Wei Wuji to agree to help, it is better to unite all countries..." ”

........

In order to increase the chances of winning the alliance with the various countries, Li Hong personally selected a few gifts, and some eloquent envoys, accompanied Li Xian to Zhao and Beiqing.

Meantime.

The capital of Yingdu of Chu.

Inside the Eldest Princess's Mansion.

Wei Wuji began the second round of research.

Right now, it's the hot season, and ice cubes are most needed to cool down.

What Wei Wuji had to do was a lot of ice, and ice cream.

This was unthinkable in ancient times.

Only in winter, the ice is transported back from the Western Regions and stored in ice cellars.

However, the Duorong tribe in the west is warlike and killing, and they do not trade.

Therefore, it is difficult for several large countries in the Central Plains to get ice cubes for storage.

In the summer, it's as hot as a dog.

The process of making ice is not complicated.

All you need to do is find one material, and that's saltpeter.

Saltpeter is placed in clean water and will quickly absorb the heat from the water until it freezes.

However, Wei Wuji searched in Yingdu for several days, but he did not find saltpeter.

In the end, he found a material called Yellowstone, which was similar to saltpeter.

He brought Yellowstone back to his house and made it himself.

Fortunately, Yellowstone is almost the same material as saltpeter and absorbs heat.

Not only in half an hour, a basin of ice was formed.

Li Bai, Chu Wushuang, and Chu Yanran, who were also standing next to him, opened their mouths wide in shock.

It was the first time they had seen that in the heat of the day, clear water could turn into ice.

How can such a miraculous thing not be amazed?

"Mowgli, you're too powerful..."

"Small."

Chu Yanran reached out and picked up a piece of ice, ready to taste it, but was stopped by Wei Wuji: "These ice are poisonous and cannot be eaten. ”

"Huh? Poisonous? Chu Wushuang was shocked.

Wei Wuji explained: "Huangshi, in itself, carries a slight poison, and after absorbing the heat in the water, the poisonous gas is even worse.

Although it will not cause obvious harm to people in a short period of time, it is also harmful to the body after a long time. ”

"Oh..."Chu Yanran was a little disappointed.

Wouldn't it be nice to have a piece of ice on this hot day?

"But it doesn't matter, we can put a small basin in a big basin.

Place the yellowstone in a large basin so that the water in the small basin slowly freezes.

In this way, you can eat slowly..."

Wei Wuji quickly got it right.

Then I instructed my subordinates to bring a little rock candy and put it in a basin.

After the basin freezes, cut it with a sharp sword.

Just like the ice cream of later generations, cut into pieces.

Chu Yanran swallowed saliva when she saw it.

After Wei Wuji got it ready, she ate a piece first.

"How?"
