Ji Yun had never tried such a high-intensity study, and he knew that if he didn't rest, he might really have an accident. Pen, fun, pavilion www. biquge。 info

So I walked out of the study and looked at the blood-red remnant sun and the clear blue sky outside, and I actually felt like I was in a different world.

Two hundred soldiers worked hard to build a house two days ago, but at this moment it was demolished and replaced with cement, Ji Yun asked Ma Yue and Li Chao to accompany him to the mountains outside the fiefdom for a walk, and followed the road map provided by Gongchuan Zhen, and soon found a large number of quartz sand and saline-alkali land.

In this southern wasteland, due to climatic reasons and historical changes, there are all kinds of ores buried in the mountains, and Ji Yun's current cement kiln uses coal as fuel.

When his mansion was built, Gong Yizhen had already thought about installing glass doors and windows for Ji Yun, and after he found the materials that Ji Yun said in the vicinity those days, he drew a road map.

The windows of Ji Yun's mansion are all glass, but the accommodation houses of these pro-soldiers are not.

That night, Ji Yun asked Ma Yue and Li Chao to control the craftsmen to make the glass, which was immediately put into use.

The houses of the soldiers are also designed by Ji Yun himself, and now with cement, the frame structure is much more convenient than the brick and concrete structure, and the two vigorous craftsmen are equivalent to the almighty, smelting steel and making steel bars, and the speed is very fast.

Fortunately, this is not a high-rise building like in the previous life, but a bungalow with a height of only four meters, and it is convenient to transfer cement, sand and gravel, but Ji Yun designed ten watchtowers on these roofs to monitor the movements of the demons.

Next to the mountain to the east of the fiefdom, several huge cement kilns were built, and another hundred soldiers were constantly making cement.

The whole fiefdom was thriving.

That night, after everyone had dinner on the roof of the bungalow that had been built, Ji Yun followed the soldiers for routine training, and then returned to the house to meditate with his eyes closed and practiced.

I don't know how long it took, Ji Yun suddenly felt a chill on his neck, he opened his eyes suddenly, and saw a blue short sword with an icy cold air on his neck, but he couldn't see the person behind him.

"It's just a fool, you're still pretending to be cultivating here, it's shameless! But your fiefdom is very well built, it's iron sand mud, right? Tell me, how iron sand mud is made!" A hoarse but murderous voice came from behind him.

Ji Yun didn't answer immediately, he looked around, the door was open, and he remembered that he had forgotten to lock the door.

"It's useless if the lock is not locked, this person can avoid the investigation of the two hundred night sergeants, and he can also avoid the investigation of Li Chao and Ma Yue's two Yellow Realm two changes, it can be seen that the cultivation is extremely high, this person can only outwit, or even outwit, but he doesn't seem to want to kill me!"

Ji Yun was not afraid of danger, he quickly calculated in his heart, deliberately took a deep breath, and his voice trembled when he spoke: "The iron sand mud is made by the vigorous craftsmen of the Gewu Zhizhi Academy, this county... I don't have that ability. ”

"Fart, I just saw that the houses of your own soldiers are also made of iron and sand, and you still want to quibble?"

"That's not iron sand mud!" Ji Yun suddenly had a kind of realization in his heart, he had roughly guessed whose order this person came, this person's goal was not iron sand mud, the production method of iron sand mud was not a secret, you could find out with a little inquiry, but the materials were extremely expensive, and only a strong heavenly craftsman or a very high cultivation Dao realm master could make it in large quantities.

Then the person's intentions are clear and clear!

"Boy, do you want to die?

Ji Yun sighed: "That's the cement I made..."

"Cement? What is that? Is it like iron and sand?"

Ji Yun pretended to be annoyed: "What do you want?"

"What can you have in this poor fiefdom? The most valuable thing is iron sand mud and cement, quickly, write me down the method of making it!" The man was obviously prepared, and handed the pen and paper to Ji Yun after speaking.

Ji Yun was full of crying: "But... But I'm here to give food to the people in this fiefdom!"

"That's good, change food or life, you choose!"

Ji Yun sighed helplessly, so he had to quickly write down the production method of iron sand mud and the production method of cement.

"Frost crystallization, sulfur mines near the volcano, or charcoal grinding into powder, and then calcining in a kiln?" After a while, Ji Yun stopped writing, and the man snatched the paper away.

"What is the frost crystal?" The man didn't pay attention to the iron sand mud, but looked directly at the method of making cement, Ji Yun sneered in his heart, and he was even more sure.

He was silent for a moment, and then his expression was solemn: "If I tell you, will you let me go?"

The man sneered: "What do I want your life for?" Ji Chongxiao, I can't afford to mess with him!"

Ji Yun completely put his mind at ease, and immediately explained: "This thing was originally covered with a shell or a salt flower on the ground and the foot of the wall, so it is called ground frost, especially in the corners of the wall near the pigsty, stables, and toilets, as well as the rock surface, caves and even saline-alkali land, which is convenient to collect, and the sulfur mine is the magma that flows out of the volcano after it solidifies, it is stone sulfur, and there are many volcanoes in my Daqian Dynasty, and there are also in this southern wilderness." ”

"As for charcoal, I don't have to explain it, do I?" Ji Yun wanted to turn around, but the short sword slammed into force, and he had to sit upright, and then spoke: "You have to remember, these things must be ground into powder, and then put into the cave where the ceramics are burned according to the proportion I said, and then set on fire." When the time comes, there will be a pungent smell, ordinary people can't bear it, it's best to be a martial arts master or grandmaster, or even a Dao realm master to guard you, you must not leave, because you must pay attention to the changes in the heat at any time!"

The man listened carefully, not even making a sound.

"The larger the capacity, the more you need to protect the master, remember! However, the larger the one-time portion, the easier it is to make the cement successful!"

"What else do you want to say?" Seeing that Ji Yun was no longer speaking, the man asked in a cold voice.

Ji Yun's mind remained at a critical point, as long as this person had the slightest abnormal movement, he immediately pressed the Enter key.

"No more. ”

Fortunately, after this person heard Ji Yun say that there was no more, he did not kill him.

"You know each other!" there was a sense of relief in his voice.

"Your Excellency..."As soon as Ji Yun's words came out, he felt a gust of wind blowing beside him, and the person had long since disappeared.

"Zhennan wait!" When the dead silence in the house returned again, Ji Yun's eyes were full of murderous intent, and three words came out of his mouth.

There is no such coincidence in the world, Mo Xiangsi wanted to buy the production method of cement from him before, and now someone has come to force him to say it, doesn't this directly point to Mo Xiangsi?

"If I can't kill you dog scraps, I, Ji Yun, will be reborn in vain!"

Ji Yun sneered, stood up and went straight to the underground secret room, this distress also made him understand a little, the big array arranged by Gong Zhen was the Xuanwu Sea Array, the Qinglong Water Absorption Array, and the Spirit Gathering Array that he wrapped around his mansion.

These three formations have no warning effect, although the Xuanwu Sea Formation has a defensive effect, but the attack against the demon barbarian does not restrict others from entering and exiting.
