Shangguan Wan'er was confused, she didn't understand what Qin Mu said at all, she just stood quietly beside him and watched the picture of Qin Mu's mobile phone sandwiched on the controller.

"Hum... Hum..."

The drone's fan began to operate, and Qin Mu pushed the rising pole to let the drone fly away from the entire mountain.

Qin Mu pointed to the screen on his phone, "See, this is the two of you, this is a bird's-eye view of Longmen Mountain." ”

Shangguan Wan'er watched intently, trying to understand how this gadget worked.

Qin Mu explained while controlling the drone, "Let's release the phoenix on this mountain when the time comes, and then float all the way to Luoyang City, from Ziwei City all the way west through Tianshan Village, and come to a clearing on this side. ”

"How far is it?"

Qin Mu pointed to the display on his mobile phone, "3.4 kilometers, about seven or eight miles, and it must be sunny that day, and it must be the morning market with the most people in Luoyang City, and it is also very important that the person in charge of filling the light in Luoyang must have a special tacit understanding." ”

"Fill in the light? How to make up? ”

"Everyone holds a copper mirror a few feet high, and reflects the sunlight at the bottom of the phoenix, and the gold leaf and gold line reflect the light, and the effect will be very good when you look at the bottom."

Shangguan Wan'er can imagine the general scene, this method seems simple, but the implementation is very difficult to cooperate.

"How did you come up with this approach? Also, how will the phoenix fly into the sky then? ”

"This method is a simple imagination, and then synthesize what can be done now, and then implement it, I can't be 100% sure of success, so we have to experiment when the hot air balloon is made."

"Hot air balloons? Isn't it just the huge spherical cloth that you made in the first place? ”

Qin Mu nodded, "Talented people are smart, it's true, the hot air balloon is the only tool that can fly in this era."

At present, only charcoal and a blower can be used as a power source for hot air balloons, which is particularly demanding in the weather. ”

"You don't have to worry about the weather, when I go back and let Li Yan of the Taishi Bureau choose the best weather in the second half of the year, we will arrange it at that time."

"Taishi Bureau, Shangguan Wan'er, it would be too condescending to let them simply predict the weather, and when the time comes, call him out to see the phoenix, is it okay?"

"Don't worry, when the time comes, the queen of heaven will hold an open-air banquet in Ziwei City, and all the officials will be there."

"That's okay, okay, the preliminary work is over here, let's talk about it when they make it, I still have something to do, I'll go back first." Qin Mu was about to leave after speaking.

"Stop! Let's talk about how to get revenge. ”

Qin Mu stopped and looked at Shangguan Wan'er, "Let's join forces to kill Xue Huaiyi?" ”

"Xue Huaiyi is a person who admires the Queen of Heaven very much, and the Queen of Heaven also trusts him very much, and often entrusts him with important tasks, and now he should be blessed by Buddhism, and it is not easy to move him." Shangguan Wan'er analyzed.

"Since he is the temple supervisor of the White Horse Temple, let's start with his life style, and you must know that the greatest punishment in the world is not to kill him."

"What's that?"

"Let him be ruined, let him be condemned and scolded by the world, and let him not be able to get along in Luoyang City." Qin Mu said viciously.

"If you need me, just say it, and I'll help you. But I want to remind you that Xue Huaiyi, Lai Junchen, and Zhou Xing are wearing a pair of pants, and if you are not careful, you are likely to be planted on this, and I will not be able to save you at that time. ”

"Whoever dares to stop me, I will let him know how to write dead words."

Lai Junchen and Zhou Xing are famous cool officials around Empress Wu, if Xue Huaiyi has a connection with them, it is likely to be a transaction of money and power, once Xue Huaiyi loses power, they will not hesitate to push Xue Huaiyi to the execution ground.

"Qin Mu, killing people can't solve the problem, you're too brutal, be careful." Shangguan Wan'er reminded her and often walked down the mountain.

Qin Mu didn't care about this, he killed all the people who threatened his life, those people also deserved to die, if he didn't kill them, he would only leave himself a hidden danger.

Compassion is the confidence of a strong man, and Qin Mu has not yet reached that level.

A week later, the steel mill on the outskirts of Luoyang was built and the first batch of steel was tested.

"Everything checked! Chairman! Can it be ignited? Uncle Zhang shouted at the top of his voice.

Qin Mu waved his arm, "Ignite!" Then he sat down on a stool and observed the situation.

Sitting next to him were Wu Zhengji, Fei Caiwen, Xiaoqing, and Ruoqin.

At this moment in history, Qin Mu wanted everyone to witness it.

"Last time it was no problem in the backyard, it shouldn't be a problem here." Wu Zhengji muttered.

"That's different, last time it was used as a cooking stove, this time it added 5,000 catties of iron ore, in fact, it can be put up to 100,000 catties, but at present it is only a trial, and stability is the most important."

Qin Mu looked at the six-person group on the side, "Wu An, come here!" ”

The six of them walked over.

"I'll take advantage of this time to give you another science popularization, this first step is charge filling: iron ore, coke and limestone are mixed in a certain proportion, which is called charge. These charges are filled into the blast furnace by means of a hopper at the top.

The second step, preheating and reduction: the combustion air inside the blast furnace enters through the furnace bottom nozzle, which causes the coke to burn and provides the heat required by the blast furnace. The charge gradually heats up in the blast furnace and the iron oxide in the iron ore is reduced to metallic iron. ”

"We all understand this, but what we don't understand is how the molten iron will become steel after it comes out, and the carbon content you mentioned earlier." Wu An asked.

"After the molten iron will go into the processing pool, generally we use charcoal as a reducing agent to refine the carbon content of the steel is too high, we need to reduce the carbon content by blowing oxygen, we do not have this condition here can only use artificial bellows instead."

Qin Mu's only concern was that the steel he refined would be greatly less durable and extensible without other alloys, and could not be used for instrument assembly.

"Then we can use the method of soap, control the number of times we stir and pull the bellows every time, and wait for the steel to cool down, and see that the material is what we need, right?" Xiaoqing interjected.

"Well, Xiaoqing is right."

The other people scratched their heads in embarrassment, and they stayed here for half a month, which was not as good as a little girl's calculation.

Qin Mu looked at the first batch of people he had cultivated, and felt a little lost in his heart, it was still too difficult for them to understand all the principles in a short time, so they could only follow the manufacturing process step by step to understand it themselves.

The flame of the furnace burned more and more, and at the same time, black smoke came out of the smoke exhaust port, and the bellows on the side rattled, and dozens of people worked at the same time.

It burned until the evening, and there was no movement.

Uncle Zhang leaned over to the water outlet and glanced inside, and shouted in surprise, "It's out of the water!" Out of the water! ”
