When Fang Changge heard the news of the shadow guard, his face suddenly burst into laughter.

He looked at the unconscious crocodile on the side and thought for a moment.

"Crocodile chief, please come here, the old man wants to show you the latest scientific and technological progress of our Datang."

The crocodile wanted to see what could make the old man smile so happily.

"Then please lead the way!"

Fang Changge walked slowly in front.

Thinking back to what the shadow guard had reported just now.

"There is news from Your Majesty that a furnace of iron has been successfully smelted, please go over and take a look."

Fang Chang Ge is not afraid of being learned by Chief Ikezawa Crocodile, after all, he has been reading books for a long time, and he has been trying for a long time before he barely succeeded in such a time, how can this be something they can learn by just looking at it?

Besides, they don't have these resources, and even if they do, it's difficult for a clever woman to cook without rice.

When they go over to take a look, they can also show him the production level of Datang, and if the crocodile has any bad intentions, it will be dispelled as soon as possible.

In the iron-making room, Li Chengzhou beckoned Han Jian and the craftsmen to pour the molten iron into the mold prepared earlier.

The molten iron is gradually cooled in the mold and eventually an iron ingot is formed.

After doing all this here, I was waiting for the arrival of Fang Changge, and the color of the iron ingots in the mold became darker and darker, and gradually took on the appearance of iron.

Fang Changge and Meng Biao took the crocodile to the blacksmith's room.

Crocodile also saw the smoke of Fire Bull City from afar, and he didn't understand what these people were doing? God mysterious.

As he got closer, he saw some shaft furnaces, some of which were broken, some of which had not yet been put into use, and Fang Changge led him to a blacksmith's room with the thickest smoke.

The crocodile saw Li Chengzhou flashing busily inside.

"Will your emperor of the Tang Dynasty also go down to work?"

Fang Changge couldn't explain that it was just that the emperor was interested in this and wanted to come up with his own iron production method.

"Learn from things! Only by doing it with your own hands can you get something really useful, and our emperor must be proficient in all kinds of things! ”

The crocodile was frightened: "What a cow! ”

Li Chengzhou was very excited when he saw Fang Changge coming, and he jumped up and shouted from afar.

"Uncle! Here and here. ”

But then he saw the crocodile walking out from behind Fang Changge.

How come the chief of this Ikezawa is here.

But since it was brought over by Fang Changge, Li Chengzhou didn't say anything, Fang Lao must have his own plans, let this barbarian see the iron he practiced, it is best to suppress him!

Several people entered the blacksmith's room, and the stuffy air inside instantly made people breathless.

"How can you stay so hot?"

The crocodile was hard to bear for a while.

Li Chengzhou's face was relaxed: "Ao, get used to it, but it's not important, come and see the iron we smelted!" ”

Everyone followed the direction of Li Chengzhou's finger and saw a few iron ingots lying alone in the mold.

The crocodile wanted to reach out and touch it, but Li Chengzhou hurriedly stopped it.

"Don't touch it!"

The crocodile rolled his eyes: "Stingy! And it won't be bad for you! ”

Li Chengzhou said helplessly: "Touch!" You go and touch it. ”

As his hand got closer to the ingot, the crocodile felt the burning heat and withdrew his hand again.

Now it was Li Chengzhou's turn to roll his eyes: "Touch?" Why don't you touch it? ”

"This is the condensation of molten iron just poured out of the shaft furnace, and the temperature is ridiculously high, so you have to dry it for a long time before you can proceed to the next step of processing."

Fang Changge looked at these iron ingots: "Is this considered a success?" ”

"Not yet, this can only be regarded as the first and most difficult step of success, and then we will have to forge these iron ingots."

"There are too many impurities in these iron ingots now, and only after further forging can the iron ingots be made purer."

"Further on, we can study steel."

Fang Changge looked at the excited Li Chengzhou.

"Alright, now that the hardest step has been completed, then leave the rest to them."

"The other matters of this Datang are still easy to deal with by His Majesty."

Li Chengzhou nodded and asked the remaining craftsmen to try again according to the successful method of this time.

Then he took Han Jian and Fang Changge back to Fire Bull City.

Li Chengzhou and Han Jian went to wash up first, and the hard work of the past few days made them full of dust, which was really not suitable for meeting guests.

After a long time, Li Chengzhou finally came out.

Looking at the crocodile who didn't say a word, he seemed to be thinking about something, and it seemed that the iron ingot had a great influence on him.

Fang Changge was discussing with Han Jian how to use these iron ingots, and the two were undecided.

"Taifu Mo is in a hurry, I also have a book here on how to use iron ingots, Han Jian will first smelt more iron after he is familiar with the iron-making technology in the past few days, and I will tell you what kind of weapon to build, it will definitely be better than the current equipment."

Looking at Li Chengzhou's confident appearance, Fang Changge knew that this kid must have something special, and he would definitely take out a book when the time came.

At this time, the crocodile, who had been silent since reading the iron ingot, spoke.

"Ladies and gentlemen, I have made a decision, and you may not believe it when I say it."

Everyone looked at each other, wondering what he had to say.

"I plan to advance the time of surrender, and before you can conquer the hot sun, I will surrender the city now."

"I can probably see your strength and potential, better than any tribe I've seen, and even comparable to several big empires in the middle of the continent."

"It's better to fall to you early, increase your strength, and also dispel your worries, you can rest assured to deal with the hot sun."

Li Chengzhou couldn't help but ask: "What are you trying to do?" ”

"I want a better future for the tribe, I also want the beautiful scenery in this world, and I also want freedom and wind."

"You don't believe it anyway, but it's true."

"Ikezawa is not like Ironwood, the large and small commanders also have an army, which leads to the lack of concentration of the chief's strength, all the power of our Ikezawa is concentrated in the hands of the chief, and there will be no resistance when you go to take over Ikezawa, and even the progress will be very smooth."

"You can completely transform Ikezawa according to your ideas, and you can make it better. Be kind to my people! ”

Li Chengzhou heard kindness and sincerity from the crocodile's words: "Don't worry, I will!" ”

Crocodile turned his head and thought about it: "I have one more request, I can go with you to Ikezawa to give up Ikezawa, but when I come back, I want to stay in this blacksmith room for a while, and I am very interested in this." ”

"After all, what really made me change my mind was that you practiced iron, I traveled to the continent before, and I heard that several empires in the middle of the continent have not mastered mature iron-making technology, but you can."

Li Chengzhou looked at Fang Changge, and Fang Changge nodded.

"No problem, I agree to your request in the name of the Tang Emperor!"
