After the day of training for the knife, Ren Baqian dragged his tired body and carried the "treasure knife" back to Pingleyuan.

"I should give you a name." Ren Baqian thought about it, Ruyi Golden Hoop Knife? Or is it called the Eternal Sword?

Ren Baqian grinned and said, "This name is good. If it can grow and grow, it is called the Eternal Sword."

Ren Baqian felt that he needed a physics laboratory, and this knife would definitely not be sent to the pharmaceutical laboratory. Unfortunately, he had no money now, so he didn't have to think about the physics laboratory. He didn't have to build it with 20 million yuan. Even if he could, he was not going to spend all the money. For the time being, he just needed to know how to use this knife. When he had money after it was launched, he would consider studying the knife.

The next morning, Ren Baqian went to the imperial kitchen with great enthusiasm to find the manager, and went to the court again.

The imperial kitchen is divided into two parts, part of which is the one he always goes to for the Empress’s meals. Now he is also responsible for his meals here.

The other part is responsible for the meals of the maids, female officials and guards.

There is also where the livestock needs to be slaughtered in the palace every day.

When I got there, I saw two giant sheep preparing to slaughter, one wild boar and the other crescent cow. In this world, wild boar is called Black Face Lord, while crescent cows are similar to buffaloes, smaller in size than horned cows, and are not good at running like horned cows.

"Kill with this knife" Ren Baqian handed the broken knife to the person who was preparing to kill the livestock. Ren Fucheng looked like he was teasing me? This knife didn't even have the tip of the knife, and it was so short...

In the end, he stabbed and killed the animals with a knife that specializes in killing animals, and Ren Baqian soaked all the broken swords into the bloody basin.

The blood of the four livestock was sucked clean by it within an hour, which surprised everyone around. In the past, the blood of a livestock could fill a large pot, but at this time it was all gone.

Ren Baqian did not explain a word, and took the knife back to Pingleyuan. As he thought about "long" in his mind, he saw that the knife grew from half a foot to six feet long, which was only two meters.

Ren Baqian pointed his sword diagonally upwards, and suddenly felt like he was like Safiros, with less flowing long hair and a leather windbreaker.

Not to mention, this knife looks a bit wide and thick when it is a short knife, but after it becomes a long knife, it looks a bit like a slashing saber.

However, Ren Baqian also found a problem this time, that is, the knife sucked the blood of four livestock, and the length was not satisfactory.

You should know that the blood you sprinkled at the beginning made it three feet long.

The blood of all four livestock was released and absorbed only six feet of light. If this were the case, the effect would not seem as great as I thought.

Could it be that only human blood is effective? Could it be that only my own blood is effective? Ren Baqian was shocked when he thought of this idea.

If you think about it carefully, the use of this knife is indeed a bit useless. Four livestock were slaughtered in the palace a day and only six feet long. At least one foot had to be left to continue using it next time. If the blade was five feet long, let eight thousand weigh it in your hand, which was only about ten kilograms. More than three thousand kilograms of iron a year is better than nothing.

Unless you send it to a slaughter and processing factory, there is no saying that a slaughter and processing factory in this world is all slaughtered privately. Could it be that there is a processing factory outside the city?

If you really want to play the role of this immortal sword, you can only do this.

Another question is that if the knife is not cut off, it will shorten after a period of time. I don’t know what the reason is, is it really because the blood absorbed by the blade disappears with time? Or is it actually increasing other aspects of the blade? For example, hardness.

Ren Baqian thought he could give it a try.

The knife was shortened and the blade body was turned back to half a foot long, and the weight was also reduced. It was similar to the weight when the knife was broken before. It was simply magical and completely incompatible with the law of conservation of mass.

However, the blade seems to be a little longer than before sucking blood.

Ren Baqian gestured with his fingers, and it seemed that it was indeed a little longer, about one centimeter.

It seems that the blood-sucking knife can grow back even if it doesn't take the broken knife back. I just don't know if it will have kidney deficiency after growing and then cutting it all the time.

After experimenting, let Baqian put the knife carefully and then received the news that the bricks had been burned. His Majesty told him to go to the Hall of Yangxin.

When Ren Baqian arrived at the Yangxin Palace, two people were already standing there, one in Tong Zhenye, and the other had never seen it before. Later, he found out that it was Shaoqing, the worker of Cao Si. The bricks and cement were first intervened by the Military Equipment Department. After all, Jingtian Furnace was also managed by the Military Equipment Department. Now the firing of cement and clay bricks has been transferred to the worker of Cao Si.

In front of Tong Zhenye, there were several bricks of street fighting artifacts.

"Ren Fucheng, do you think this is correct?" Tong Zhenye said after Ren Baqian greeted him.

Ren Baqian looked up at the empress and looked at the bricks with joy. They felt good, had a smooth surface, and were very heavy. They were not as rough as modern red bricks, because there was no coal ash added inside. Although it was a bit troublesome, it was the best quality, and it had been for hundreds of years without breaking.

When I broke the bricks, I saw that the inside was also very dense, unlike the red bricks with coal ash that were black inside.

Ren Baqian smiled after careful inspection: "That's it. It's much easier to burn bricks like this than to use cement to build them."

The other people also nodded, it was indeed the case.

"That's it. The Ministry of Works hastened the time to burn these bricks and cement to build a glass factory. If you have anything to understand, please contact Ren Fucheng." The empress nodded and said.

All of them received the order.

Ren Baqian returned to Pingleyuan again and took the drawings of the unearthed earthen kiln to hand them over to Tong Zhenye. The current earthen furnace burns bricks and cement at a speed that is too slow and the quantity is too small.

If Da Yao hadn't relied solely on wood to burn it now, Ren Baqian would rather make a rotary kiln, which would greatly increase the speed of burning bricks and cement.

"It is best to place the location of the earth kiln a little further, and it is a good place to take the location of the clay." Ren Baqian reminded.

"Why?" Tong Zhenye asked curiously. It is much easier to transport clay than bricks, and in that case, most craftsmen would have to live there, and the transportation of food and other supplies would cost more people.

If you do this, the consumption of materials and manpower will be much greater.

"Otherwise, a large number of floating objects burned in the air in a few years, and you can't even see the stars when you look up." Ren Baqian said, "It's almost like everyone is responsible for protecting the environment and leaving a blue sky for future generations."

He didn't want to spend more than ten or twenty years, and he would be filled with haze every day when he opened his eyes, like a fairyland.

However, it is still difficult for Tong Zhenye to understand. After all, people in this world have never seen what air pollution is.

"As Ren Fucheng said," the empress decided that Ren Baqian had much more knowledge than them in this regard.

Tong Zhenye nodded and responded.

Then Tong Zhenye looked at Ren Baqian with an extremely strange look, making Ren Baqian fur all over.

"What's wrong?" Ren Baqian was not sure.

"I heard Tonglan say something about Ren Fucheng's affairs. Ren Fucheng's shamelessness is quite as good as my old demeanor." Tong Zhenye stroked his beard, looking admiring. But even the fool could see that his eyes were full of contempt.

A few days ago, His Majesty recruited Tonglan into the palace and said he was a training partner. Tong Zhenye didn't think much about it. Although Tonglan is young, it's okay to hit three or five of them with one hand.

But when Tong Mansion was having a meal, he asked casually, and when he heard Tonglan talk about what happened in the afternoon, he sprayed it directly.

Not to mention him, even the others in the Tong Mansion were shocked.

In front of His Majesty, he was so shameless when facing a ten-year-old child. Not only did he dare to mention a brothel, but he could also threaten him with such words that he would not pay back the money. It was simply eye-opening.
