After entering the cave on the wall of the deep pool, Lin Mu found that the cave was not a little long. It was winding down for nearly 1000 meters. If it wasn't for the martial arts above the natural environment, it would be a dead end for anyone to enter the cave.

The warrior in the congenital environment can change the original pulmonary circulation breathing into internal breathing, that is, the infant's breathing mode in the mother's body, and exchange the external air through the whole body's skin and external contact. This is an important ability to enter the congenital environment, and also one of the important criteria to distinguish whether to enter the congenital environment.

The cave not only meanders long, but also has many branches. For several times, the forest and animal husbandry have gone through the branches, and finally found that it was a dead end. Then they went back to find other paths, until nearly an hour later, he finally emerged from the water.

At this time, even he did not know where he was. He only knew that it was an underground cave, and there was no other way to get out of it except the water channel.

This mysterious cave alone has blocked all the martial arts below the natural environment. They have no ability to breathe inside. Even if they know a clear path, they can't support themselves to enter this underground cave at one breath.

However, just when Lin Mu just came out of the water, within a few seconds, his heart suddenly became extremely alert. The cave was dark without any light source, but his mind could perceive that there was a uniform vibration on the dry ground in front of him.

After a careful induction, he immediately identified the vibration caused by breathing.

Lin Mu gently separated from the water and swam to the bank. Then he came out of the water quietly. In order to avoid the unknown monster discovering his arrival, he didn't dry his clothes with genuine Qi, for fear that the monster was born with keen intuition and felt his breath.

Lying on the ground, the even rhythmic tremor from the ground can be found that the monster should be sleeping now.

In order to prevent the monster from perceiving itself, Lin Mu did not use mindfulness to observe the situation in front of him, because mindfulness is a kind of spiritual energy. Although ordinary people can't feel it, animals with keen perception are likely to find the existence of this energy. The monster in front of him can't say it's perceivable.

With his right hand, an energy-saving lamp appeared in Lin Mu's hand. It was a kind of lamp with very weak light source. It was not very bright. If it was used for illumination, he would only be able to see the road under his feet. However, Lin Mu's five senses were different. He had too many senses beyond ordinary people. As long as there was a trace of light source, he could see the scene around him.

Quietly pressed the switch of the energy-saving lamp, the weak blue and white light immediately lit up the scene around Lin Mu. It was also the first time that light appeared here since the cave appeared. The long dark white broke, and the surrounding scene immediately impressed Lin Mu's eyes.

The cave is not very big, that is, less than a thousand square meters. The ground is rugged, with many grotesque stones on the ground. There are no messy plants. The only clue of plants is that in the deepest part of the cave, a corner of a huge petal is exposed, and from the color, it is still dark.

Seeing the corner of the flower, Lin Mu was very happy. Seeing the corner alone, he knew that he had found the right place this time. This is the mysterious place where you Yongwei's family had been told by word of mouth, where mandala and jiutuora grow.

However, before the joy in his heart dissipated, another thing came to Lin Mu's mind, that is, the monster who was entrenched here. According to the past experience in Xiuzhen world, it was not an accident that the monster found here. It was obviously aimed at something here, otherwise he would not sleep in this dark place.

Then Lin Mu looked at the weak light source. Although he could see it in dim light, the efficiency was a little slower than when it was bright. After all, he also needed to distinguish what he saw. For ordinary people, he was afraid that other places were still dark.

After looking back and forth for three or four times, he finally determined where the monster was. Not far away from the black petal with a corner exposed, there were large pieces of strange stones standing. Under one of them, there was a long tail with blue black pattern. From this tail, we can see that the monster must be a snake.

After walking slowly, Lin Mu converged his own breath to the extreme. Without necessity, he didn't want to fight with this huge snake in the cave. Although he has entered the congenital environment, there are still many powerful animals in nature, which are naturally stronger than human beings. It's better not to provoke them easily.

In the area of breath convergence, Lin Mu did a very good job. He walked slowly in the cave like a ghost. When he passed the stone pillar where the monster was sleeping, he looked at the monster.

Giant is his first thought after seeing it. It's bigger than the largest snake, the serpent in the Amazon jungle. It has a full body of more than 20 meters by sight. Its body is as thick as a bucket and is coiled into one circle after another. Its huge head is buried in the center of the circle. The whole body shrinks and relaxes regularly.

Since the huge snake was sleeping soundly, Lin Mu naturally didn't want to wake it up. After walking quietly, he saw 14 Bingdi flowers growing here behind the stone forest, but five of them had been eaten, and the broken bite marks, It shows that these flowers were eaten by the huge snake outside. Despite his heartache, Lin Mu carefully picked off the remaining nine rare flowers, eight of which he only picked petals, and the last one he pulled up and directly put into the ring. If this kind of rare flower can be cultivated in the outside world, then he won't have to go all the way here in the future. So far, he doesn't know anything about the growth habits and years of this kind of flower, and he doesn't know how to cultivate this kind of flower, but it's not a big problem. You can study it slowly when you go back. There's plenty of time to do these things. The most urgent thing is to leave this place first. However, things changed in the next moment. As soon as Lin Mu collected the flowers and was ready to leave, he turned around and saw a huge head standing high in the air of the cave, looking down at Lin Mu from a height of about three meters. The huge head is bigger than Lin Mu's whole body. The two yellow eyes are as big as Lin Mu's two heads. The typical narrow pupils of snakes are shining with dangerous light. However, this strange snake has obviously survived for many years and has a trace of spirituality. Looking at Lin Mu, it is obvious that it is the first time that it sees a person in this cave. But the next moment, a huge hissing sound comes from the mouth of the strange snake. Because in the process of raising his head, the strange snake saw the place with strange flowers behind the stone forest. Unexpectedly, there was no flower left. All that was left was the bare flower pole. The obvious anger was clearly conveyed from the strange snake's eyes. The huge tail suddenly swept away and instantly swept all the stone pillars around. For a moment, there were huge stones flying everywhere in the cave. After clearing the obstacles around the body, the snake's tail turned into a phantom, and with a shrill whistling, it swept directly to the position where the forest stood. This is just the first attack of the strange snake. In the second attack, the huge mouth of the strange snake shows four ferocious fangs, each of which is as long as a Nepalese dagger. Under the illumination of the energy-saving light in the hands of Lin Mu, it flashes cold light. As soon as the snake opened its mouth, two clear and transparent liquids came out of the snake's mouth. The speed was extremely fast, even faster than the snake's tail. After that, it shot at Lin Mu. His heart sank slightly, and Lin Mu sighed to himself. He didn't expect that such careful action would wake up the huge strange snake. However, in the cave environment, he didn't think it was a good choice to fight with the strange snake. Even if he wanted to fight, he had to fight on the ground. After he made up his mind, his body swayed slightly and disappeared directly from the strange snake's face bridge. The next moment he appeared, he had already reached the edge of the deep pool. At this time, the venom from the snake's mouth could be shot at the place where Lin Mu stood before. A stream of smoke immediately rose from the ground and corroded a huge hole in the ground. The thick tail swept that position in the next moment, set off a fierce wind, and even cleaned all the gravel around. However, Lin Mu can't manage all this. He has got bingdiqihua now. He just needs to leave here safely. So when he got to the edge of the pool, without any hesitation, he dived directly into the pool and rushed back to the direction he came. This time was different from when he came here. At that time, because he didn't know the way, he had to worry about when the huge monster in the pool would appear, so he swam very fast. He even used his real Qi to accelerate, trying to make himself move faster in the water. As Lin Mu disappeared into the deep pool, the cave was dark again. A huge roar suddenly exploded in the cave.
