In the tent of the Tianlang Emperor.

As soon as Huyan Huaer left, the Lord of the Wolf Temple said, "Your Majesty, is your method effective for the King of the Desolate State?"

The Emperor of Heavenly Wolf smiled mysteriously: "How can I know if I don't try it?"

The Lord of the Wolf Temple nodded and said, "That's right!"

"You'll know after trying!"

On the other side.

On the side of the Huangzhou General's tent.

The rows of iron pots lined up in a row, and the water inside was boiling.

The soldiers in charge of logistics in Huangzhou quickly brought the boiling water into the wooden barrel, moved it to the side, added fine salt to let it cool.

Then, continue to take water from Yinshan River and boil water.

at this time.

The first pot of boiling water has cooled down in the wooden bucket.

Xia Tian took Baihu, Li Jian, Eunuch Wei, and Bai Feng out of the tent and came to the wooden barrel.

As soon as Xia Tian stretched out his hand, Bai Feng took out a wooden box from the military tent full of supplies, opened it, and held it respectfully in front of Xia Tian.

I saw that there were white objects in the box, with different shapes.

In summer, take out a piece from the box and put it in cold boiled water.

Suddenly, a trace of cold air evacuated from the barrel.

As time went by, I saw that the bucket of cold boiled water condensed into ice and emitted a cold air.

Baihu, Baifeng, and Li Jian were unmoved at all.

But Eunuch Wei was shocked!

What did he see?

Is it the technique of turning water into ice?

suddenly.

Eunuch Wei remembered the head of the python dragon that Xia Tian sent into the palace.

He thought of the ice wrapped around the dragon's head!

So that's how it was made!

It's so amazing!

All the way through summer, all the cold boiled water in the wooden barrel condenses into ice, which is extremely magical!

finally!

Eunuch Wei stared at the white crystal in Xia Tian's hand and asked, "Prince, is it because of this white gadget?"

Xia Tian nodded and said, "Yes!"

"What's the name of this thing?"

"Saltpeter!"

Saltpeter, making is not difficult!

Just find the nitrified soil block, mash it and place it in a bucket, soak it in water to get the solution.

Then filter, boil or dry the filtrate to obtain saltpeter crystals.

When the desertion was in summer, a small piece of land containing sulphur was found on the edge of the 100,000 mountains, and some saltpeter was extracted.

Some days ago, the wasteland sent dragon meat to various places in Daxia, and it was all up to this thing to freeze the meat to keep it fresh.

"General Bai, carry the ice to the mountain so that the soldiers can hold ice cubes on their mouths to relieve the heat when logging wood!"

"yes!"

Bai Feng immediately executed: "Come on, carry it up!"

Eunuch Wei looked at the buckets of ice catching the cold air on the mountain, and was curious in his heart as if he was a cat's claw: "Eat ice in June, it's so lucky for the soldiers in the desert to eat! "

"Prince, how do you make saltpeter?"

Xia Tian finally waited for this question: "Eunuch Wei, if you show me your father's secret edict, then I will tell you how to make saltpeter!"

Eunuch Wei's face froze: "Prince forgives me, it's really not time now!"

Xia Tian was not disappointed: "Then can you tell me... Your original name was Long Nitian, why did you change your name to Wei?"

Eunuch Wei's expression was even more stiff: "Prince, I can't say this now!"

Xia Tian said seriously: "When in the palace, the villains in the palace often sarcastically at me. Why do you always protect me?"

Speaking of this, Xia Tian's eyes burst into light: "Is it because we are all around the Emperor of Daxia and have the word "tian" in our names?"

Eunuch Wei was shocked!

The Ninth Prince has such a keen intuition!

He forced a smile and said, "Prince, don't think too much. Old slave is a slave of the Xia family. It is natural to be nice to the prince."

Xia Tian didn't believe it, but he no longer asked: "Can you tell me what my father wanted to do if he imprisoned my mother in Gushan Hall?"

Eunuch Wei looked at Baihu deeply: "Go back to the prince, in order to find the first sword saint of the previous dynasty!"

Baihu's eyes glared: "Old eunuch, what are you watching me do?"

"Do you think I am the first sword saint of the previous dynasty?"

Eunuch Wei refused to comment: "Although your face looks strange, I always think you are a familiar person."

"You must be an old friend of my father-in-law!"

The white tiger raised his eyelids: "My old friend has eggs!"

"You have no eggs like this, no!"

"you......"

Eunuch Wei was furious!

Suddenly, the two invincible masters glared and looked at each other, as if they were about to fight!

Summer is helpless!

This old guy successfully changed the topic and deserves to be the chief manager around Xia Zhou!

There is a set!

"alright!"

Xia Tian interrupted the two of them’s fighting spirit: “At present, unity and external affairs are the most important thing, and I will not allow internal friction!”

"yes!"

Baihu and Eunuch Wei went down the steps!

Then.

Eunuch Wei continued to change the topic: "Prince, why do you put salt into the bucket?"

Xia Tian smiled casually: "For people, salt represents strength!"

"When the weather is hot, a lot of sweating will take away the salt in the body, making the body weak. At this time, the most important thing to supplement is salt.

"So, we must use salt water to replenish the salt in the warriors' bodies and replenish their strength!"

Eunuch Wei thought for a while: "Prince, does the saint really know everything?"

Finally, the conversation entered the key part.

Xia Tian curled a smile of a little fox on the corner of his mouth: "Eunuch Wei, how do you think about the problem of my king having the wisdom of a saint?"

Eunuch Wei looked solemn, looked at Baihu deeply and said, "Your Majesty seems to think that the prince is immortal!"

"He always has deep expectations for the prince!"

"If the prince is immortal, in the future, Your Majesty will have something to use you!"

Xia Tian's eyes lit up: "Whose person are you?"

Eunuch Wei directly turned back to the smiling face that was indifferent to the salt: "Prince, I am serving Your Majesty in the palace, so I am naturally your Majesty's person!"

Xia Tian's eyes flashed with wisdom, staring at Eunuch Wei and said, "No matter who you are now, I hope you don't harm me!"

"Is this the prince's warning?"

"yes!"

"I understand!"

Eunuch Wei said meaningfully: "Prince, although what you did from the imperial capital to the deserted state is secret, the old slave holds the Imperial City Department and knows a lot of things!"
