Limestone can be used to burn lime to make cement, and is also an important flux for iron and steel making. His Majesty the Emperor must like this as one of the most important golden fingers for time travellers.

Although he can quickly build a house by relying on his system skills, the emperor can't expect Bai Yuqi from all over the world to help him build turrets, right? He is not a professional brick-moving member of the construction team.

Quartzite can be used to burn glass, although now it can also be used to make glass through [Fossil to Sand] and [Sand to Glass], but due to material limitations, the output of the glass produced is low and the quality is not good.

Needless to say, kaolin clay, the legendary Guanyin clay, is a good treasure for making porcelain... Bai Yuqi was thinking about it, and suddenly discovered a very serious problem!

Although these things he thought of were all weapons used by time travellers, the problem was that apart from reading novels and knowing some general principles, he didn't know how to do it at all?

For example, when it comes to cement, he knows that cement is made by burning, but it must not only burn limestone, right? There must be something else added? The question is what should be added?

And burning glass, surely it’s not just putting quartzite in and burning it to produce a pot of glass, right? I don’t understand these details at all!

According to this, the various time-travel weapons he has seen in novels cannot be used at all, right?

For example, if fat is used to make soap, what should be added? If nothing is added, wouldn't it make people hungry if it simmers?

There is also the so-called steel-frying method. Bai Yuqi knows that he needs to stir it with a stick and sprinkle carbon powder. The question is how much to sprinkle? What is the ratio?

"Damn this lousy writer made a mistake for me! Why didn't he write it clearly?"

Bai Yuqi angrily threw the branch on the ground. Feeling uneasy, she picked it up and threw it away again!

Behind him, Sun Laodao and Yuchi Baolin had meow-meow-meow expressions on their faces, completely unable to understand what he was talking about.

Apart from Bai Yuqi, who is a loser, there is no one who has made a fortune from the content of novels.

He didn't even think about the details. Not to mention that few writers really understood them. Even if there were writers who really understood them, would readers be willing to read them if they were too detailed?

"Forget it, food is the most important thing for the people, I'd better raise pigs!"

Bai Yuqi was frustrated and used [Earth Moving Technique] and [Fossils to Mud] to remove the soil and rocks covering the veins at several iron mines.

Then use [Rock Collapse Technique] to break up the veins, pick up some iron ore and use [Refining Technique] and [Extraction Technique] to extract iron and other metal components.

Then use [Metal Dissolution] to soften, and [Shape Technique] to shape, to create a batch of mining tools such as "shovel, shovel, pickaxe, hoe, drill, hammer, drill", throw them casually in the mine, and tell Yang Tieniu to summon them.

Refugees come to mine.

Then he turned around and called Sun Laodao to go back. Sun Laodao, who didn't know what he wanted to do, quickly followed.

But Yuchi Baolin hesitated and quietly fell a few steps behind.

When the two of them walked a little further, they quickly picked up an iron drill and weighed it in their hands.

Then he suddenly used his strength to chisel into a rock. When sparks burst out, a rock was directly chiseled off by him with brute force!

Yuchi Baolin couldn't help being surprised: "Is this fine steel?"

Just now, he witnessed with his own eyes the little doll-like omnipotent immortal, using his magic to lift up the soil, peel off the rock formations, and absorb iron and stone to turn into various tools!

In disbelief, he pulled out the horizontal knife from his waist, holding the knife in one hand and the drill in the other, and slashed hard. He heard a crisp clang of gold and iron and flying sparks. Only a shallow mark was left on the iron drill, and his

A gap the size of a soybean appeared in the Bailian Hengdao!

Yuchi Baolin gasped, holding the iron drill in her hand tightly and refusing to put it down. She cast her eyes on the tools on the ground, and her heart was bleeding!

This kind of fine steel is actually used to make tools?

If it were made into a weapon, it would be a magic weapon!

Yuchi Baolin's eyes turned red as she wished she could pick up all the tools on the floor and carry them away.

If they could learn the magic of making weapons, wouldn't the soldiers under the Tang Dynasty be invincible?

The iron drill is too long and is too conspicuous to carry on the body.

Yuchi Baolin reluctantly touched it again and again, and then she could only put it down again.

Instead, he picked up a hoe that had not yet been equipped with a wooden handle. He looked around and saw no one was around, quickly stuffed it into his arms and turned around to run away.

He found a Qianniu Guards soldier and gave him a hoe wrapped tightly in the cloth torn from his inner robe. He shouted in a low voice: "Send it back to Chang'an quickly and present it to Your Majesty in person. There will be no mistakes along the way!

Otherwise we will destroy you! Leave quickly!"

The captain, who was usually like a brother, suddenly said such serious words.

The Qianniu Guards soldier couldn't help but be startled, and immediately reacted and stuffed the cloth bag into his armor.

Then he grabbed a war horse and ran towards the city gate like he was running for his life, even pulling out the sword from his waist for fear of being blocked!

But no one cared about his actions at all. The gate of Kuyu City was originally guarded by the Qianniu Guards. Besides, the gate didn't even have a door panel. Who would stop him?

Even if there were refugees working near the city gate who saw a horse galloping away, they would just look at it and then lower their heads to work, rushing to earn work points.

What does those military masters running around on horses have to do with them? Dozens of them have been running around in the past few days, is there anything strange about them?

Watching the soldiers disappear on the Kuyu stone road, Yuchi Baolin breathed a sigh of relief.

Not caring about the theft he had just committed, he rushed straight to Bai Yuqi's location. He decided to follow the little immortal from now on!

There are so many good things in this Wanxiang Wuji Gate!

The nine-day sun furnace in the Tiangang Zhiyang Formation can produce thousands of stones of salt every day without any one person working!

On this hot day, even the refugees were drinking ice-cold black bean water with large pieces of ice floating in it. You know, even His Majesty is reluctant to be so extravagant!

And...when she thought of herself looking around stupidly in Kuyu City a few days ago, Yuchi Baolin felt so heartbroken that she couldn't breathe, feeling that she had missed hundreds of millions!

Bai Yuqi had no idea that an iron tool made of a metal formula that he randomly fused with iron and various extracted metal elements, and accidentally formed, would actually cause such a big reaction from Yuchi Baolin.

He was squatting next to the pig pen, staring at the pigs like his father who were being served by the refugees, and asked Sun Laodao without looking back: "What a wonderful response! You are a medical student, can you groom pigs?"

"Gelding pig?"

Sun Laodao couldn't help but be dumbfounded. He studied medicine well, but he didn't study veterinary medicine?

This man has studied castration, but he has never gelded a pig before... Besides, this pig is fine, why are you gelding it? Is it provoking you?

I haven't learned any medical skills since I became a disciple of my master. Instead, I learned a lot of strange magical techniques for building houses and paving roads. Finally, the topic that had something to do with medical skills was about veterinary technology. This made the old man feel a little embarrassed for no reason.
