The sun is shining, on a beautiful hill, and on the sunny side are exquisite houses, neat and orderly. Then on the mountain, the shade of green trees, a scene of paradise.

The two of them walked on the path in the forest, it was the wood forest and the little six who led the way.

"Why don't you go down the mountain, but choose to go around from that side of the mountainside to this side of the mountainside?" Mu Lin wondered.

"There's no way, no one is allowed to approach below, so if you want to go to the forging pool, you can only go around here. ”

"Aren't there any guards?" Mu Lin asked suspiciously, looking at the deserted, even a little desolate back mountain.

"There is nothing here except the forging pool, and the children of the Yu family can enter the forging pool when they are old, so there is no one to guard it. ”

"How long can I stay in the forging pool?"

"As long as you can stand it, you can stay forever, but almost two hours is enough for ordinary human immortals, and I stayed for almost an hour last time. ”

"Oh, but I heard that there is a jade child in your Yu family, who is very beautiful, I don't know if I can see it, or ······"

"Shhhhh

"What's wrong?" Mu Lin pulled away Xiao Liu's hand, his face full of "doubts".

"It's not something you should take care of, just hurry up and get out of the way. ”

"What a strange person. Mu Lin muttered, but his eyes rolled, and many thoughts in his heart had been confirmed.

"It's here. Xiao Liu pointed to the front and said.

I saw that in the forest, a pool of about ten zhang was like a pearl, inlaid on this low blue mountain. In the middle of the pool is pitch black water, calm without a trace of ripples. The moment Mu Lin looked at the pool water, he felt that there was a special magic in the pool that attracted him.

"Tianlin!Tianlin!What's wrong with you?"

"Ahh

"It's okay to go in directly, but remember it's better not to move, I'm waiting for you here. ”

"Okay! I see, thank you. ”

Mu Lin walked to the side of the pool, frowned and looked at the deep black pool water, but did not hesitate too much, and jumped straight down.

The leap into the woods, the splash in the pool water did not stir, and it was still as calm as ever.

"Hiss!" The moment Mu Lin went down to touch the pool water, dozens of black energy directly drilled into his skin, and Mu Lin's whole body was full of spirits.

The black energy was like a small snake, scurrying through the skin, muscles, and even meridians of the wood. But this energy seemed to be much smaller than gas, and there was no painful sensation, but an itch, a feeling that seemed to be in contact, but there was no real sensation of contact, which made Mu Lin's nerves feel extremely itchy.

"Ahh

But at the same time as it itched, Mu Lin realized that the black unknown energy had melted into his body. In the muscles, some gray impurities visible to the naked eye were discharged, and the strength suddenly became stronger.

After that, the muscles seemed to be free of impurities, and the black energy became thin and continued to move on to other parts.

Mu Lin felt the strengthening of his body, and he was also silently sensing the breath of black energy. Mu Lin had seen a potion to strengthen the body before, but there were really many side effects, and basically not many people would use it.

However, Mu Lin had inquired about the forging pool of the Yu family before, and most of the Yu family had used it, and there was nothing abnormal so far.

It is also because of this that Mu Lin will come to try it for himself now, but this kind of breath is really not to pull out the seedlings. If the method of squeezing potential is used, the vitality will be severely weakened, and at this time, Mu Lin feels that his vitality is not only not weakened, but more vigorous.

This discovery made Mu Lin very happy, this is a great thing, and his vitality will also affect his cultivation speed to a certain extent, and this time, his speed can be further improved.

After knowing the benefits of the pond water, Mu Lin sank down and buried his entire body, including his head, in the pond.

"Shhh Once moved, it is easy to cause uneven energy, and the effect will not be perfect.

Feeling his throat and even his eyes hardening, Mu Lin knew that this time was the right time.

But a scream came from the bottom of the water, which made Xiao Liu, who was listening on the shore, itch his scalp, as if he remembered his experience of going in, and Xiao Liu's face turned a little pale. He knew the power of this pool of water, not to mention that it didn't move like Mu Lin, even if he couldn't stand it directly, he had repeated it three or four times, going in and out, going in and out, before he barely completed the forging.

An hour passed, and as time passed, the itchy numbness on Mu Lin's body gradually weakened.

"No wonder the maximum time is two hours, and the effect of the enhancement has become smaller. Mu Lin thought to himself.

Another half an hour passed, and the itchy feeling was about to disappear, indicating that it was about to have no effect, and Mu Lin now expected it to be like the itch at the beginning.

"Alas, it's a pity, my body is almost equivalent to the eightfold of human immortals, and if I take a few more steps, I may reach the ninth level, and it seems that there is no chance. Although Mu Lin felt a little pity, he was also very satisfied.

Because his strength is difficult to increase, his grandfather said that his current physical condition is not suitable for cultivating that kind of body refining exercises, and Mu Lin is also very envious of Huang Ji's power of body refining. It's a real surprise to have this kind of opportunity now.

"But the internal organs still seem to be a little weak. Mu Lin closed his eyes and frowned slightly.

"Well, it seems to work. A thought suddenly appeared in Mu Lin's mind, but it was more dangerous.

"And it seems to be a little dirty. ”

Mu Lin had a fierce confrontation in his heart, but he still decided to "take a risk" and give it a try.

"Hopefully no one has showered here or anything. Mu Lin's heart was crossed, his mouth opened, and the black pool water was forced into his body, close to his internal organs.

"Shhhh

Black energy surged, crisscrossing the body of the wood. It's like 10,000 cat's claws scratching the heart, liver, spleen and other extremely sensitive parts, which is even more unbearable than stimulating the muscles at the beginning.

After another hour of torment, Mu Lin felt that his nerves were about to collapse. But the effect is also obvious, in the past, there would be internal injuries when you were slapped with a palm, but now you won't be easily injured, unless you are a master of the Earth Immortal Period.

At the same time, he found that the pool water that had entered his body had become transparent and had no effect.

"It seems that this black energy is the main thing, and water is just the medium. ”

With the improvement of Mu Lin's whole body strength and strength, he decided to go out, but at the moment when he was about to go out.

"No, my dantian?"
