Limestone can be used to burn lime for cement, and it is also an important flux for iron and steelmaking, and His Majesty the Emperor must have liked one of the important golden fingers of this traverser.

Although he can rely on his system skills to build a house quickly, the emperor can't expect Bai Yuqi to help him repair the turret, right?

Quartzite can be used to burn glass, although now he can also make glass from [fossils to sand] and [sand to glass], but due to material limitations, the production of glass is low, and the quality is not good.

Needless to say, kaolin, the legendary Guanyin clay, a good treasure for burning porcelain...... Bai Yuqi thought about it, and suddenly found a very serious problem!

The things he thought of, although they were all serpents of the traverser, but the problem was that he didn't know anything about it except for reading novels.

For example, cement is known to be burned, but it must not only be limestone? There must be something else to add? The question is what to add?

And burning glass, it's definitely not a pot of glass if you put quartzite in it, right?

In this way, the various crossing weapons he saw in the novel are completely unusable?

For example, if you don't add anything, won't you be hungry if you boil it up?

There is also the so-called frying steel method, Bai Yuqi knows that if you want to use a stick to stir it, you have to sprinkle toner, the question is how much to sprinkle? What is the ratio?

"Damn the second writer mistook me for a big thing, why didn't you write it clearly?"

Bai Yuqi angrily smashed the branch bar in his hand on the ground, feeling unrelieved, picking it up and throwing it again!

Sun Laodao and Yu Chi Baolin behind him had meows on their faces, and they couldn't understand what he was saying at all.

made a fortune from the content of novels, except for Bai Yuqi, who has no future.

He doesn't want to think about those details, not to mention that few writers really understand, even if there are writers who really understand, can readers be willing to read them if they write too much?

"Forget it, the people take food as the sky, I'll still raise pigs!"

Bai Yuqi was deflated in several iron mines, using [Soil Removal Technique] and [Fossil to Mud] to remove the soil and rocks covering the ore veins.

Then a blow of [Rock Collapse] shatters the ore veins, picks up some iron ore and uses [Refining] and [Extraction] to extract iron and other metal components.

Then use [metal dissolution] to soften and [shaping] to make a batch of mining tools such as "shovels, shovels, pickaxes, hoes, drills, hammers, and drills", and throw them in the pit, and tell Yang Tieniu to gather the displaced people to mine.

Then he turned his head and beckoned Sun Laodao to go back, and Sun Laodao, who didn't know what he wanted to do, hurriedly followed.

And Yu Chi Baolin hesitated for a moment and quietly fell a few steps behind.

When the two of them walked a little farther, they quickly picked up an iron chisel and held it in his hand.

He suddenly chiseled a rock with force, and a rock was directly chiseled down by him with brute force when the spark burst out!

Yu Chi Baolin couldn't help but be surprised: "This is stainless steel?"

Just now, he had witnessed the little doll-like Vientiane Immortal, using immortal magic to lift up the soil, peel off the rock layers, and take out iron and stone to turn into various tools!

In disbelief, he pulled out the horizontal knife at his waist, and slashed with the knife in one hand and the other in the other, and heard a crisp sound of gold and iron and sparks, leaving only a shallow mark on the iron drill, and his hundred refining horizontal knife actually collapsed into a gap the size of a soybean!

Yu Chi Baolin gasped, held the iron drill in her hand and was reluctant to put it down, her eyes fell on the tools all over the ground, and her heart was dripping blood!

How can this steel be used to make tools?

If it is made into a weapon, it is a proper magic weapon!

Yu Chi Baolin, who couldn't wait to pick up all the tools on the ground and take them away, had red eyes.

If you can learn the immortal method of making weapons, wouldn't the soldiers under the command of the Tang Dynasty be invincible in the world?

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

After Yu Chi Baolin reluctantly touched and touched, she could only put it down again.

Instead, he picked up a hoe that had not yet been fitted with a wooden handle, looked left and right and saw that there was no one, quickly stuffed it into his arms, covered it, turned around and ran.

Find a Qianniu guard, stuff him with a tight hoe wrapped in the cloth torn off his inner robe, and shout in a low voice: "Send it back to Chang'an quickly, and present it to Your Majesty in person, and you must not lose anything along the way! Otherwise, you will be killed!

The captain, who is usually like a brother, suddenly said such heavy words.

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

Then he pulled a war horse and fled to the city gate, afraid that someone would block it and even pull out the horizontal knife at his waist!

But no one cares about his actions at all, the gate of Kuyu City was originally guarded by their Qianniu Guard, and the gate doesn't even have a door panel, who will stop him?

Even if some of the homeless people working near the city gate saw a horse galloping away, they would at most look at it and bow their heads to work, rushing to earn their wages.

What does it have to do with those military masters running around on horseback? They have been running dozens of them in the past few days, what's so strange?

Seeing the figure of the soldier disappear on the Kuyu stone road, Yu Chi Baolin breathed a sigh of relief.

Ignoring the theft he had just done, he hurriedly went straight to Bai Yuqi's location, and he decided to follow the little immortal step by step from now on!

There are so many good things in this Vientiane Infinity Gate!

The Nine-Day Sun Furnace in the Tiangang Solstice Yang Great Array can produce thousands of stones of salt every day without the need for one person to work!

On this hot day, even those homeless people drank chilled bean water with large ice edges, you must know that even Your Majesty is reluctant to be so extravagant!

And also...... Thinking that she had been looking around in Kuyu City stupidly a few days ago, Yu Chi Baolin was so heartbroken that she couldn't suck it, and she felt that she had missed hundreds of millions!

Bai Yuqi didn't know that the iron tool made of a metal formula that he had accidentally formed by fusing iron and extracting various metal elements would actually cause such a big reaction from Yu Chi Baolin.

He was squatting beside the pigsty at this moment, staring at the pigs who were being served by the homeless people like his father, and asked Sun Lao without looking back: "Miao Ying! You are studying medicine, do you know how to gelding pigs?"

"Gelding?"

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

He had studied this man in such a gelding, but the pig really had never been gelding...... Besides, this pig is so good, what are you gelding it for?

Since worshipping under the master's door, medical skills have not been learned at all, but have learned a bunch of strange fairy methods for building houses and paving roads, and finally talked about a topic that has something to do with medical skills or veterinary technology, which makes the old man inexplicably a little messy in the wind.
