Ultrabasic evolution

He moved forward to the nest of the Vajra Bull while hunting down the Vajra Bulls he could find.

The closer he got to the nest, the more Vajra Bulls there were. All the Vajra Bulls he killed were mutated and ascended without exception.

The strange thing was that, except for the large Vajra Bull he encountered at the beginning, which was at the ninth level, these mini Vajra Bulls were at most at the third level, and most of them were at the first or second level.

After killing more than a dozen Vajra Bulls, Lin Shen finally came to the nest of the Vajra Bull, lurking on the top of a nearby mountain, and peeking at the nest of the metal bull.

Lin Shen found that the nest of the Vajra Bull was a huge round pit, and there were many caves on the mountain walls around the round pit, which Lin Shen had seen before.

However, from the perspective of a giant at that time, he didn't feel that there was anything special about the caves.

But from the perspective of now, it is a very huge project to make so many caves on the mountain wall, which looks very spectacular.

An astonishing number of Vajra Bulls went in and out of those caves, running in different directions to find that special metal fragment.

Lin Shen got several pieces of that metal fragment, but he didn't understand why. He only knew that this metal fragment was much harder and more ductile than the ordinary metal on the Golden Star.

It looked a bit like jade, but its characteristics were still those of metal. It was hard and ductile.

There were too many diamond bulls below, and Lin Shen didn't dare to take the risk to hunt them. It would be troublesome to be surrounded by them.

Anyway, he had already obtained a lot of mutation ascension fluid and spiritual base, enough for him to use for a while, so there was no need to take risks now.

Lin Shen hid in the mountains, observing the diamond bull's nest, and kept drinking the mutation ascension fluid. He continued to drink it after digesting it, hoping to reach 100% base mutation rate as soon as possible.

The Golden Star also has the sun as a light source, but the day here is much longer than that of the human mother planet.

When night came, Lin Shen felt the temperature around him drop sharply.

The Golden Star is extremely hot during the day, but terribly cold at night. The environment is too extreme, and even Lin Shen feels a little uncomfortable. It is probably extremely difficult for ordinary ascenders to survive here, and it is impossible to survive here for a long time.

Those Vajra Bulls actually abide by the law of working from sunrise to sunset and resting from sunset. When night falls, most of the Vajra Bulls return to their nests.

Some Vajra Bulls left their nests too far away, and did not have time to return to their nests before nightfall. Their bodies gradually stiffened in the extreme cold, and soon they stood there motionless as if they were frozen.

"Although the temperature at night is very low, it is not low enough to freeze the ascended creatures. There is a problem here!" Lin Shen thought about it, quietly went down the mountain, and sneaked towards the frozen Vajra Bulls.

Along the way, Lin Shen was carefully testing and investigating, and soon confirmed that there were indeed no Vajra Bulls in the nest who would come out, and the Vajra Bulls outside had indeed lost their ability to move.

Lin Shen came to a Vajra bull. No matter how he pushed it, it didn't react at all. It was like a golden statue, not a living thing at all.

"Strange, the Vajra bull's body is so strong, how could it not withstand such a little low temperature?" Lin Shen was even more confused.

However, this discovery made Lin Shen much bolder. Anyway, the Vajra bull couldn't come out at night, so he had nothing to fear.

Lin Shen didn't kill the frozen Vajra bulls, so as not to alarm the Vajra bulls in the nest with the sound.

He quietly came to a cave entrance in the nest, wanting to see what was going on inside.

The cave turned not far after extending in. Fortunately, there was only one passage, not a complicated structure.

After hesitating for a while, Lin Shen decided to go in and take a look. Anyway, there was only one way. If there was any danger ahead, he would just run out directly, and those Vajra bulls would not block him outside.

Lin Shen came to the turning point of the cave passage quietly and looked inside quietly.

This sight almost frightened him to death. His body reflexively used the shrimp-slip technique to bounce back. The speed of retreat was incredibly fast, and he retreated several meters in an instant.

At the corner of the passage, there was a diamond bull, staring at Lin Shen with wide eyes. Just now, Lin Shen looked into its eyes and his face was almost touching its face.

Soon Lin Shen found that this diamond bull was also frozen and could not move at all. It was impossible for him to attack him.

"Scare me!" Lin Shen rubbed his heart, which was beating wildly. He almost had a heart attack just now.

"The diamond bulls who returned to the nest were also frozen and could not move. Why did they rush back to the nest?" Lin Shen felt more and more strange in his heart.

Going around the diamond bull, Lin Shen continued to walk into the cave. On the way, he saw several diamond bulls that were frozen and could not move.

Bang!

As Lin Shen continued to walk forward along the cave, he suddenly heard a dull metal collision sound coming from the depths of the cave.

Lin Shen stopped immediately, pressed his body against the cave wall, and stared at the front.

But nothing appeared in front of him, instead he heard another crisp metal collision sound.

This collision sound was much crisper and lighter than the previous one.

Dang! Ding! Dang! Ding! Dang! Ding!

Two sounds, one heavy and one crisp, appeared repeatedly and rhythmically. The more Lin Shen listened, the more he felt that the sound was like the sound of iron forging.

Before the advent of mechanized iron forging, two people were needed to cooperate in the hammering stage of iron.

Generally, the apprentice held the big hammer and the master held the small hammer. Where the small hammer fell, the big hammer followed.

The master's small hammer was a baton, and the apprentice's big hammer was used to hammer the iron. Through the cooperation of the two, they were constantly trimmed and beaten, and finally forged into an ideal state.

At this time, the sound Lin Shen heard was like two people working together to forge iron, and the rhythm and sound were very similar.

"How could someone forge iron in such a place? This is the nest of the Vajra Bull, there can't be anyone, right? No matter how smart the Vajra Bull is, it's impossible for them to use tools to forge iron with their hooves, right?" The more Lin Shen listened, the more strange it felt.

Unable to suppress his curiosity, Lin Shen continued to go deeper into the cave.

Along the way, he saw many Vajra Bulls whose heads were immobile like statues, which made Lin Shen feel even more strange. He couldn't figure out what was forging iron.

The cave twists and turns, but there is no fork in the middle. I walked all the way to the end and found a cave at the end.

Lin Shen stretched his head to look into the cave and saw a strange scene.
