The Ulu from Asgard is a peculiar metal with very different physical properties from those found on Earth.

So much so that Tony Stark and Fitz, two generations of scholars, have failed to break the deadlock, and their research on Ulu has so far been clueless.

"Mr. Stark, isn't there any progress?" Luo Xiu walked to the console and asked in a low voice.

"This damn alien metal is a bit tricky, and Fitz and I haven't figured out a good way to deal with it yet." Stark said in a deep voice.

"Why?" Luo Xiu asked.

"It's so hard that it's hard for us to split it, and at the same time it's so high that it has surpassed the melting point of tungsten." "In short, this guy is invulnerable and invulnerable. ”

"Is the melting point so high that it can't melt it? This should not be the property of a metallic element. Luo Xiu frowned, "Generally speaking, the melting point of metal crystals is relatively low, only higher than that of molecular crystals, and considering that the Wulu that makes the armor should be an alloy, its melting point should be lower." ”

"That's right, I'm also wondering." Stark said: "According to the scientific theory on the earth, Wulu should be an alloy, because its hardness is extremely high, but the ductility is extremely poor, even if it has withstood such a violent and frequent impact today, it has not been able to deform it, and metal crystals composed of metal bonds cannot have such stable characteristics, and their ductility is very good." ”

Luo Xiu nodded: "That's true." ”

"But in terms of melting point, the melting point of Wulu is even higher than the highest melting point of atomic crystals on earth, and only crystals formed by strong covalent bonds connecting atoms can reach such a high melting point, and alloys cannot reach this point." Stark said in a deep voice.

"So, it's not accurate to define Ulu as metal?" Luo Xiu asked.

"At least we can't jump to conclusions until we see its microstructure." Stark spread his hands, "But now we can't even melt it, let alone observe its microstructure." ”

"What about forcibly looking at it directly with a transmission electron microscope?" Luo Xiu proposed a rather unreasonable approach.

"Please......" Stark pointed to a lump of Ulu armor fragments in the lab, "just put this thing on the TEM?" There was nothing to see at all, nothing but darkness. ”

Fitz also said helplessly: "If there are metal fractures or broken marks on the armor of the Destroyer, then we may be able to obtain the microstructure of the crystal through a metallographic microscope or a scanning transmission electron microscope, but this armor is so strong that it does not even have cracks on it." ”

Tony nodded, "We must disassemble the armor before we can analyze it, but ordinary tools can't disassemble this weird thing." ”

"Hmm......" Luo Xiu thought for a while, and suddenly had an idea in his mind.

Ulu is indeed an anomalous substance, and even vibranium, the toughest metal on Earth, can't destroy Ulu, but when Thor uses the teleportation machine to dive into the crater to get a hammer, Thor's hammer seems to react violently with the teleportation machine.

The outer material of Thor's hammer is Wulu, and the energy source of the teleportation machine is the Cosmic Rubik's Cube.

Does this mean that the energy released by the Cosmic Cube can destroy the Ulu?

"Don't worry, I have a way to break down the black road." Luo Xiu said, and after speaking, he turned around and went back to his laboratory to prepare the Cosmic Rubik's Cube.

"What can this kid do?" Tony Stark asked Fitz suspiciously.

Fitz blinked and thought for a moment, and speculated, "Maybe it'...... Magic? ”

Tony Stark spread his hands noncommittally and continued to bury his head in research.

——————

Luo Xiu, who returned to his laboratory, continued to use alchemy to prepare a replica of the Cosmic Rubik's Cube, which was quite a heavy job.

Busy until the early hours of the morning, Zhenma suddenly broke in, and seeing that she didn't even bother to knock on the door, Luo Xiu guessed that she had made a breakthrough.

"Any good news? Zhenma? Luo Xiu put down the wand in his hand and asked with a smile.

Zhenma nodded, "Yes, there is good news!" Xiu, I found a key ingredient in the divine blood, and this ingredient is in an abnormal state, limited by some potential power and inactive, maybe this is the key to Thor's loss of divine power! ”

"Let's go, let's take a look!" Luo Xiu immediately put down his work and followed Zhenma to the life science laboratory.

The computer in the lab showed an analytical diagram of the cells, apparently the "key ingredient" described by Zhenma.

"Xiu, you see, this is a certain kind of blood cell that I found in Thor's blood, although it is quite different from the morphology of human blood cells, I found that it is essentially similar to hematopoietic stem cells in human blood......," Zhenma said excitedly.

"Oh, I'll take a look." Luo Xiu pulled a stool and sat down in front of the computer, then carefully examined the cell structure diagram on the monitor.

Zhenma explained methodically on the side: "At first, I didn't find the characteristics of this cell, because the cells of the Asgardians are too different from the cells of humans, but after I found the pattern, I found that there is a commonality between this cell and human stem cells......"

As she spoke, Zhenma opened another picture.

"These are the regular blood cells in the blood of the gods, which can be thought of as the red and white blood cells in human blood – although their morphology is very different, their functions are similar."

Luo Xiu nodded: "It can be imagined." ”

Zhenma said: "Now when we look at the difference between this kind of stem cell and blood cells, we will find that stem cells have some characteristics: for example, we can see that this kind of cell has a very low degree of differentiation, has multi-directional differentiation potential, has the ability to self-renewal, and can divide and proliferate without limit......

Hearing this, Luo Xiu suddenly realized: "And the above characteristics are all biological characteristics of stem cells, that is to say, the cells you observed are indeed hematopoietic stem cells." ”

Zhenma nodded at first, then immediately shook her head.

"It's a stem cell, yes, but it's not necessarily a blood cell, because as you can see, the ability of these stem cells to divide and proliferate is blocked, and they haven't proliferated at any time since they were collected by me, which is very strange......," Zhenma whispered.

"If the proliferation of this cell is blocked, but Thor's blood cells are not missing, then it means that the stem cells are not hematopoietic stem cells, but have other functions." Luo Xiu immediately smoothed out the logic.

And Thor now, the only thing that is sealed is his Thor's power.

Therefore, the stem cells in front of you are most likely the stem cells that gave birth to the power of Thor Thor!

"Zhenma, we seem to have found the key to unlocking the power of Thor." At this time, Luo Xiu also became excited.
