At this time, everyone was attracted by Li Zhi's operation.

They curiously gathered around Li Zhi, wanting to see what he would do next.

I saw that Li Zhi asked Liu An to pour the contents of the big cloth bag into the two water tanks and put the two copper basins into each other.

After doing this, Li Zhi opened his mouth and said to everyone: "Everyone, the next time to witness the miracle has come. ”

Just after Li Zhi's words fell, white gas suddenly began to slowly emerge from the water tank, which had just been calm.

Soon, everyone felt a chill emerge from the water tank in amazement.

The chill quickly relieved the heat on their bodies and made the temperature around them lower and lower.

Then everyone was shocked to find that the water in the tank began to freeze slowly, and even the milk in the copper basin began to slowly solidify.

At this time, everyone was already speechless in shock, and they all opened their mouths wide, staring wide-eyed to see the subsequent changes.

Li Zhi can only be held by Liu An at the moment because of his short stature.

He saw that the milk in the basin was almost solidified, so he immediately asked Bakken to put the mold into the basin.

He then instructed Bakken to insert the bamboo sticks into the small grids that were divided by the molds.

The next step is to wait for the milk to solidify completely.

Taking advantage of this gap, Li Zhi opened his mouth and explained to Li Shimin: "Father, the emperor, and his sons discovered that saltpeter has the effect of absorbing heat in the process of developing gunpowder with Liu An. ”

Li Shimin asked in surprise: "You mean that saltpeter is put in the tank?" ”

Li Zhi nodded and said, "Yes, father, the son used the characteristics of saltpeter to make an ice drink for you and your adults to cool off. ”

Fang Xuanling on the side said: "I can't imagine that the inconspicuous saltpeter has such a wonderful use, it's really strange." ”

The eldest grandson Wuji said: "The pheasant slave's research on the way of things has really reached an unprecedented achievement, and in a short period of time, he has contributed several important materials to my Datang. ”

Everyone nodded after listening to the words of the eldest grandson Wuji, and they all looked at Li Shimin with envy on their faces.

Wang Jue took the lead in congratulating Li Shimin and said: "It is the blessing of Your Majesty to get this Lin'er, and it is also the blessing of my Tang Dynasty." ”

After hearing this, the others also spoke: "Congratulations to Your Majesty, congratulations to Your Majesty." ”

Li Shimin laughed and said: "Don't praise anymore, lest the pheasant slave be proud." ”

Pei Kuanshu said with a smile: "Your Majesty, you can rest assured, His Royal Highness King Jin has always been approachable and has never been arrogant. ”

Yan Lide also said on the side: "Whether it is talent or character, the teacher is enough to be a teacher, and it is a great fortune for the minister to be fortunate to worship the teacher." ”

Li Shimin saw that everyone praised Li Zhi again and again, and he was already so happy that he couldn't find the north.

He laughed and waved his hand, "You have said it, you have said it. ”

Li Zhi was in Liu An's arms, and he really got goosebumps when he heard it.

So he glanced at the popsicle that had already been formed and said, "Father, uncle, my lords, the ice drink is ready to eat." ”

After listening to Li Zhi's words, everyone hurriedly shifted their attention to the copper basin.

Li Zhi instructed Bakken to take out the popsicles in the copper basin one by one and distribute them to everyone.

He saw that everyone was holding popsicles and was a little overwhelmed, so he stuck out his tongue and licked a popsicle under everyone's tangled gaze, and then took a small bite.

When everyone saw Li Zhi's demonstration, they immediately tried his example.

Immediately, there was a series of moans of great enjoyment.

The cold feeling and the strong milky fragrance opened all the pores of everyone's body.

The occasional breeze swept through them and carried away all the remaining sweat from their bodies.

At this moment, everyone has completely forgotten that they are in the hot summer, and there is a sense of refreshment all over their bodies.

The cold air emitted from the water tank also effectively lowered the surrounding temperature, which also made them feel less anxious in the rest of the wait.

It wasn't long before there was a burst of cheers in the ironworks, followed by an excited runner running out.

As he ran, he excitedly shouted, "Success, we succeeded!" ”

When Li Shimin heard this, he immediately greeted him.

He grabbed the craftsman's arm and asked, "Did it really work?" ”

The craftsman had long been so excited that he had forgotten his humility, and he said happily: "It worked, it really worked!" ”

Li Shimin immediately ran quickly to the factory, and the others hurriedly followed.

As soon as everyone came in, they looked up at the blast furnace.

Bakken had crawled to the side of the observation hole by this time and took a serious look.

After a while, he shouted at Li Shimin: "The molten iron has been burned, please order Your Majesty to open the furnace." ”

Li Shimin waved his hand and said, "Open the furnace!" ”

After receiving Li Shimin's order, two people immediately opened the discharge port with a long iron hook.

Then I saw the red molten iron slowly flowing out of the blast furnace with flames.

The molten iron flows down the pre-laid grooves and is quickly guided into the molds.

Li Shimin watched all this nervously, he was waiting for the last drop of molten iron to flow out of the blast furnace.

At that point, we will be able to confirm the final yield and see if it will be increased tenfold as Li Zhi said.

The answer was soon revealed, and after the molten iron ran out, a worker quickly reported a number from his mouth: 30,000 catties.

Everyone was frightened when they heard this number, and several gasps sounded at the scene one after another.

Li Shimin turned his head to look at the people around him in disbelief, and found that they were all as shocked as he was.

He asked again in a slightly trembling voice: "Are you sure it's three... 10,000 catties? ”

The worker replied excitedly: "Your Majesty, it's 30,000 catties, it's really 30,000 catties!" ”

After hearing this positive number, Tobe Shangshu Dai Xuan muttered on the side: "Earned!" Earned! ”

Of course, everyone knows that this investment is earned, not only earned, but also made a lot.

As the top officials of Datang, how could they not know Datang's annual steel production?

It is precisely because of this that they are so shocked at this moment.

Before that, the annual steel output of the entire Datang was only about 2 million catties.

Now, just this blast furnace has refined 30,000 catties at a time.

The main thing is that the refining time is only three hours, which is less than half the time before.

At this time, everyone's eyes when they looked at Li Zhi completely changed.

If they looked at Li Zhi with amazement and exclamation before, then at this time it has completely turned into admiration.

They had begun to ignore Li Zhi's age, and regarded him as a capable general who was enough to be on an equal footing with them.
