Lamp?

Obviously, in terms of Fang Qingzhen's understanding, she said with an innocent look, "Is it a very powerful magic weapon?"

Lu Donglai thought about it, an object that can emit light freely should be considered, and nodded lightly, "En." ”

"Sure enough, it's Senior Brother Lu, it's really amazing, can I see Senior Brother Lu refining this magic weapon, Senior Brother Lu's magic weapon must be very powerful!" Fang Qingzhen looked excited.

This is a loyal fan!

But......

Seeing Lu Donglai's hesitant appearance, Fang Qingzhen seemed to know that he had lost his words. Yes, if someone else refines magic weapons, there must be a secret in it, and if this secret is known, it will be lost to a craft.

Just as he was about to say, 'Senior Brother Lu, I'm sorry, I shouldn't have said something like that, I'll leave first', but Lu Donglai raised his head slightly and said, "If you're not bored, it's okay." ”

"Really?" Fang Qingzhen became more and more excited, he was so happy to be able to witness Senior Brother Lu refining magic weapons!

Lu Donglai felt that Fang Qingzhen was making a bit of a fuss, just a light bulb, and the entire cultivation world should be popularized by then...... He was merely a guide, carrying the electric light to every monk's home.

Soon, Lu Donglai's gaze shifted to the broken stones on the ground.

It is said that it is broken stones, but these things are the residues left over from refining weapons, and it can be said that they are ores, and they are by no means as simple as stones, which must contain elements of other metals.

What Lu Donglai has to do is to distinguish and refine these metals one by one.

At present, the third master is the only one who can do this.

When Lu Donglai went to the third master with this lump of things and explained his intentions, the third master was stunned, "Apprentice, do you mean to turn this stone called 'ore' into several kinds of metals?"

Lu Donglai nodded, "That's right." ”

The third master came to Lu Donglai and touched his forehead lightly, "I'm not sick~ How can I talk nonsense?"

During the whole process, Fang Qingzhen and Lu Xianzhen stood aside and watched, Lu Xianxi covered his mouth and snickered, his brother was so often pitted by several masters, and Fang Qingzhen was dumbfounded, it was the first time she had seen that the relationship between the master and apprentice could be so harmonious, and sure enough, Ziyuan Immortal Mansion was a magical place.

Lu Donglai shook his head, "Of course I'm not sick." ”

Then, Lu Donglai used a simple physics to describe the refining method of this ore.

When the third master heard this, he was stunned for a while, and then he spoke, "Apprentice, do you mean ignition? Does each metal contained in this ore have its own ignition point? Why did you never know it before you became a teacher?"

Lu Donglai nodded, "In physics, every object has its own ignition point, and it is difficult for us to use minerals at ultra-high temperatures when we usually use them, even when we build weapons, the temperature of these minerals is only maintained at a little more than a thousand degrees." ”

Although I have forgotten a lot of knowledge in physics at the beginning, such as copper, zinc, aluminum, silver and other ignition points, I still have a relatively clear understanding of the temperature of the flame and the temperature of coal.

When this remark came out, not only Fang Qinghal and Lu were stunned, but even the third master was shocked, "Why do you know so much, apprentice?"

Lu Donglai thought about it for a while, and began to say goodbye to himself, he couldn't say that he came through time and came with the memories of his previous life, it was terrible.

Soon, Lu Donglai weaved a set of rhetoric in his mind, which could be completely justified.

"Well, I had some dreams a few days ago, and there was a white-haired old man in the dream who gave me this knowledge, and the old man was quite old, for tens of thousands of years, his surname was 'Ke', and his name was 'Xue', and then I simply called him the old man of science. ”

"Strange surname, unheard of, maybe this is your creation, grasp this knowledge will benefit you a lot in the future. ”

Regarding the lies woven by Lu Donglai, the third master immediately believed it, after all, the fate of the apprentices was something that several of their masters could not calculate, and it was normal to have a special encounter that ordinary people could not understand.

Some people are born ordinary, but it is not by chance that they get the guidance of other people's dreams, and in just a few years, they continue to break through and become powerful beings.

There are also some people who are reincarnated by some great powers, who have sealed their memories, waiting for their memories to be unsealed, and they have also soared into the sky.

As for their own apprentices, several of their masters believed that this was by no means an ordinary person...... Can ordinary people be so lazy? Maybe this was a great power in the last life!

Naturally, she has always believed in her apprentices.

Lu Donglai nodded, knowing that the third master had promised himself, but he quickly added, "Third master, you must not use the highest temperature at the beginning, because in that case, the temperature is too high, and the melting point of all metals will reach at the same time, so it will be impossible to distinguish the metals in it, and you must ......start with 1,500 degrees Celsius first."

"What is fifteen hundred degrees Celsius?" the third master looked puzzled.

Scientific idiots.

Lu Donglai said again, "It's probably you, the third master...... Oh, by the way, what is the maximum power of your flames, for example, what can you burn?"

The Third Master replied, "Samadhi is true fire. ”

Lu Donglai heard the words and nodded, the samadhi true fire is really the three temperatures of fire in the wood, fire in the stone, and fire in the air, for example, the flame mountain in Journey to the West is caused by the samadhi true fire, and the temperature is about 15,000 degrees Celsius. (Some people say that Samadhi is really 60,000 degrees, don't be elegant, this is a novel.) ）

After a pause, Lu Donglai spoke, " Third Master, first burn these ores with a flame of one-tenth of your strength, if these ores do not change, continue to increase the temperature until the liquid is produced in them, maintain this temperature, collect this liquid, and make sure that there will be no more liquid, and then increase the temperature, increase the temperature by one percent at a time, slowly increase, and repeat the cycle is almost like this, among so many ores, if you want to refine, you should still be able to refine two or three kinds of metal substances, and if you are lucky, there may be four or five kinds. ”

Hearing this, the third master nodded, "Okay." ”

Just as he was about to turn around, he glanced back at Lu Donglai again, "Disciple, did that senior called science say what this classic is?"

Lu Donglai is a serious way, ""Heat and Energy of Matter in Junior High School Physics". (To be continued.) )
