The two-meter-high stove is painted with yellow paint, and there are many testing instruments placed outside.【】

This is an internal combustion furnace. The temperature inside the furnace can reach thousands of degrees. The entire room is shrouded in high temperatures. Even if heat insulation measures are taken, the surface temperature is forty or fifty degrees.

But even for such a stove, the outermost layer is covered with a thin layer of ice.

The ice particles in that layer are fine and crystal clear, and have never melted away.

The pipes that deliver hydrogen fuel to the furnace are frozen under this layer of ice, and only a small part of the hydrogen is delivered.

Li Minghua walked over, pulled down a gate, and turned off the running furnace.

I saw the pointers of the testing instruments outside the furnace flying, and finally stopped at the zero mark.

It can be clearly felt that the temperature of the entire room is dropping.

Just then, the ice on the stove began to melt, turning into water droplets and dripping down.

Han Ze already knew the reason for this, so he walked over and opened the stove with his bare hands.

"Hey, don't touch it, be careful of getting burned." Zhao Hong said hurriedly.

Although the stove is turned off, the high temperature on the surface in some places still poses a certain danger to people.

Bah...

There was a sound of high-pressure gas being released, and countless smoke rose from the furnace.

The experiment was suddenly filled with a pungent and unpleasant smell.

Li Minghua turned on the exhaust fan at the right time to pump out the gas. Otherwise, if someone inhales the gas, something will definitely happen.

Han Ze looked inside the furnace and found that it was a double-layered furnace. The outer layer was the heating system and the inner layer was the working system.

At this time, there is still some black substance floating on top of the melted material in the inner furnace.

"What kind of mineral powder was put in?" Han Ze asked, and he found that things did not seem to be as simple as he imagined.

Li Minghua moved quickly and brought over an enamel tray with more than ten glass bottles on it. Each bottle contained a kind of mineral powder, which was colorful and really beautiful.

Later, Li Minghua asked Zhao Hong to bring over a tray filled with various reagents.

Seeing how diligent Li Minghua was, Zhao Hong was even more confused.

What happened to the boss today? Why are you willing to be an assistant to this guy who seems to know nothing? This is not in line with the boss's style.

But Zhao Hong didn't dare to ask, after all, he was just one of the many graduate students under Li Minghua.

Han Ze picked up a bottle of mineral powder, opened the glass stopper, and poured it directly into the stove.

"You..." Even Li Minghua was not calm now, because the weight of the mineral powder used in this experiment was measured in micrograms. It was impossible for Han Ze to accurately control the weight.

But when he thought of Han Ze's amazing calculation process, Li Minghua stopped talking.

Zhao Hong on the side finally couldn't help it anymore and said with some dissatisfaction: "Do you know anything about experiments? The weight of these things must be accurately calculated before they can be used. What if you break the stove later?"

?”

Such a stove looks ugly, but it is expensive, close to one million.

Han Ze raised his head, glanced at Zhao Hong, and said, "Why don't you come? Your teacher hasn't even spoken, you are the only one who talks a lot. And isn't it just a stove? If it breaks, I'll be with you!"

Han Ze now has the card given by Zhang Tianxiong and is considered a rich man. Therefore, although this is his first time operating this kind of stove and he is not completely sure of success, he is not afraid of breaking it.

After adding several more mineral powders, Han Ze turned off the stove and asked Li Minghua to open the gate.

After a while, the whole furnace started to work.

The ice outside the stove surprisingly did not appear this time.

"Tch, if you don't have enough materials, that kind of strange phenomenon will definitely not happen. After you put in all the materials, this problem will still not be solved." Zhao Hong said disdainfully in his heart.

After all, in his opinion, Han Ze is just a young man who doesn't understand anything.

Li Minghua glared at Zhao Hong and said, "What are you doing standing still? Why don't you quickly write down the process!"

Although he knew the theoretical process, Li Minghua knew nothing about the specific operation and attached great importance to this process.

Although Zhao Hong was disdainful of Han Ze, he followed Li Minghua's words without hesitation. He took a notebook and wrote down all Han Ze's steps.

After not heating for long, Han Ze turned off all the instruments. After the temperature of the furnace reached a certain value, he opened the furnace again and added materials into it.

This went back and forth until more than four hours had passed, and Han Ze had only the last material left in his hand.

"Huh?" Han Ze picked up the glass bottle in his hand and looked at it.

The glass bottle is only ten centimeters high, and there are many crystal white crystals inside, just like salt.

But if you look closely, you will find that there is a faint red color in these crystals.

"Blood?" Han Ze smelled a faint smell of blood from these crystals.

Han Ze was certain that this was not a deterioration of the crystal, but blood stains that had stained the crystal.

What surprised Han Ze even more was that these crystals actually contained spiritual energy, and the purity of these spiritual energy was different.

"Spirit Mine!" Han Ze immediately thought of this kind of thing.

Spirit Mine, as the name suggests, is an ore that contains spiritual energy. It is said that the Spirit Mine was formed at the beginning of the birth of a planet. At that time, the spiritual energy on a planet was the richest. Many ordinary stones were soaked with this rich spiritual energy.

Hundreds of millions of years of sedimentation have formed the spiritual minerals.

Spirit mines are divided into nine levels according to the concentration of spiritual energy they contain.

The small bottle of spiritual mineral in Han Ze's hands at this moment, although it is not even the lowest level of spiritual mineral, but in this earth where the spiritual energy is turbid and exhausted, it can be regarded as a rare treasure.

"I never imagined that such a thing could exist on earth." Han Ze thought to himself. The biggest problem hindering Han Ze's practice at the moment was spiritual power.

But this small bottle of spiritual mineral powder surprised Han Ze.

Afterwards, Han Ze opened the furnace and put in some spiritual minerals.

Zhao Hong watched helplessly as Han Ze put in the last material, but the strange phenomenon did not appear again. He couldn't help but mutter to himself: "This...how is this possible? This is unscientific!"

Because Han Ze's solution is extremely simple and can be operated by just one person, but this simple operation solved the problem that the entire team had made no progress for more than a month.

"What's so unscientific!" Li Minghua glared at Zhao Hong and said, "This is science. Your basic knowledge is so poor, you have to go back and make up for it!"

As for the calculation method given by Han Ze, Li Minghua would not leak it easily. Although the principle is simple, in Li Minghua's view, if he mastered it himself, there would be no problem in winning a provincial science and technology award.

Zhao Hong did not dare to refute Li Minghua's criticism and could only nod in agreement.

"By the way, can you check the source of this bottle of material for me?" Han Ze asked, holding the bottle of spiritual mineral powder.

Although Han Ze knew that this hope was slim, he still wanted to try.

Nowadays, cultivation resources on the earth are too scarce, and Han Ze urgently needs all the resources he can find.

"What's wrong? There's something wrong with this mineral powder?" Li Minghua asked.

"No, I just want to know more about it. You also know that the appearance of this thing in the furnace is very interesting, isn't it?" Han Ze started to make up, naturally he would not say that it was a spiritual mine.

In the calculation process given by Han Ze, there is indeed a material that will produce a strange reaction, but it is not this kind of spiritual mineral at all.

Li Minghua seemed to remember that there was indeed such a thing, and said with a smile: "Then I will ask someone immediately to ask about the source of this mineral powder."

Later, Li Minghua took Han Ze and said that he would treat Han Ze to a meal to thank Han Ze for solving this problem.
