Zhang Che worked hard in the beast world, and Huang Tielan, a classmate from Qianwei City, was also not idle.

She felt that she had lived a very fulfilling past two days.

In addition to going to the military experimental base every day to make a simple beast culture liquid to practice, the iron boy girl insisted on learning to do weight loss exercises in the gym every morning and evening with her mother Zhong Yuqing.

At this moment, she was sitting upright in the familiar beast cultivation liquid production room, looking at a bronze quality alien beast card in her hand, and a large pile of strange medicinal materials on the side, her eyes were full of determination.

"Come on, Huang Tielan, you can definitely do it!"

Since successfully cultivating and upgrading a clawed fanged dog beast card a few days ago, the iron boy girl has increased the difficulty for herself and began to cultivate this bronze quality beast card in her hand.

In the past three days, she has failed more than twenty times in a row, and the total value of medicinal materials consumed has reached tens of thousands of alliance coins, but she has not succeeded once.

In the meantime, there was even an explosion due to operational error.

Fortunately, the iron boy and girl had already taken precautions, and with the flexibility that was different from the fat body, she suddenly hid under the wide experimental table, which escaped the risk of disfigurement.

In the next operation, Huang Tielan was even more cautious, resolutely not letting go of any detail, lest there be a trace of mistakes.

"The concentration of red leaf grass sap must be controlled between 86% and 87%, and the order of addition must be ...... after 15 seconds of miscanthus sap"

While the iron man and girl were engrossed in operating the equipment on the table, squeezing out the essence of the juice from different kinds of medicinal herbs, and then adding them according to a strict procedure, she was still muttering to herself in her mouth to achieve the effect of reminding herself.

Finally, when all the ingredients had been added and nothing was wrong, the Iron Man closed the lid on the petri dish, put it in the transparent heating device, set the starting temperature, and turned on the power.

"There can't be any more explosions, the things here are dead and expensive, if you blow up a few more sets, the father who slammed the door will have to say me again." ”

The iron boy girl's fat face was full of concentration, her eyes were staring at the mixed juice in the petri dish, and her right hand was directly placed on the temperature regulator of the heater, so as to adjust the temperature according to the color change of the culture medium for the first time.

The knowledge involved in this is extremely complicated, and it must be familiar with it in order to avoid problems in actual operation.

It can be said that every successful beast cultivator is a top student among top students.

Gradually, the liquid in the Petri dish becomes warmer and hotter.

When it was about to reach the boiling point, Huang Tielan's eyes were quick, and she immediately turned off the heater, and then waited expectantly.

Eventually, the slightly cloudy liquid in the petri dish quickly became clear, and the color took on a uniform pale powder.

"Yay, half the battle!"

Huang Tielan cheered, waved her fist fiercely, and waited until the culture liquid returned to room temperature, immediately opened the lid and put the prepared bronze beast card into it, and then quickly re-closed the lid and used a vacuum machine to drain the air inside.

Half an hour later, when Huang Tielan took out the card that already had an extra six-pointed star on the card surface, her eyes were full of hope.

"I will definitely be able to be admitted to the Royal Beast Cultivator major of Beidu University, for the sake of Zhang Xiaoche!

"What is this?"

With the green light emitted by the pile of green fluorite behind him, Zhang Che finally found a black crystal the size of a finger from a pile of rubble.

Under the illumination of green light, this irregular black crystal was like a small black hole, completely engulfing the green fluorite light that came through.

However, Zhang Che doesn't know this thing.

He took the black crystal in his hand and checked it, it felt much lighter than ordinary steel, but it was obviously heavier than a stone, it must be a rare metal mineral.

It seems that when you have leisure in the future, you still have to familiarize yourself with the relevant memories left by your predecessor, otherwise you will not be able to recognize any rare minerals at first sight.

Zhang Che secretly made up his mind, and immediately began to look up in the memory hard drive, wanting to see what kind of mineral this black crystal was.

However, I couldn't find ......

Zhang Che rummaged through the memory hard disk left by his predecessor, but he couldn't find the slightest information about this black crystal.

"Could it be that I've discovered a new rare mineral?"

As soon as this idea was born, Zhang Che became inexplicably excited, if this is the case, then it will be terrible!

However, there is another possibility, that is, the black crystal that Zhang Che found was a useless ordinary substance at all, because it was too ordinary, so it was not stored in the memory hard drive by the predecessor.

"Let's leave it at that, let's continue to look for the Amethy Lazuli. ”

Shaking his head and placing the finger-sized black crystal next to the green fluorite, Zhang Che began to look for it again in the piles of rubble.

In less than a minute, as he pulled open another pile of rubble, a black crystal the size of a walnut reappeared in his sight.

"Strange, why is it this black crystal again?"

Zhang Che was even more puzzled in his heart, picked up this black crystal the size of a walnut, and looked up and down, left and right, but still couldn't make any new discoveries.

Could it be that the information seen by the predecessor is wrong, and the purple lazuli is not associated with a large amount of green fluorite?

This is not very likely, these news are generally the conclusion of many field explorations, how can it be so easy to make mistakes?

There was no way, Zhang Che could only continue to rummage in the other gravel piles again.

When the third black crystal appeared in front of Zhang Che, he finally stopped the movement in his hand and looked at the third and largest black crystal in his hand in a daze.

Compared to the other two black crystals, this one has a more regular shape, the size of a baseball, like a simple carved gemstone, and the whole body is black and faint, as if it wants to swallow up the surrounding light.

No matter how Zhang Che looked, he felt that the shape of this black crystal was very similar to the shape of the purple crystal in the memory hard drive.

But the colors of the two don't match at all!

Could it be that this black crystal is really a rare mineral that has never been discovered?

The purple gold crystal was obviously missing, and Zhang Che didn't know what this black crystal was, so he simply stopped, preparing to get out of the cave and go to the mountains outside to hunt a large alien beast.

Well, most of the day has passed, and Zhang Che feels that he is already hungry again, so it is better to go out and eat something, and it is not too late to come back and continue to explore this cave.

Because it looked extremely beautiful, the black crystal the size of a baseball was directly held in Zhang Che's hand and played with it, not resting on the ground.

When Zhang Che walked out of the cave and got used to the dazzling light outside, his eyes inadvertently swept over the multi-faceted crystals in his hand, but his body suddenly stiffened, and his mouth opened wide in surprise......
