When Lei Haoyun went to the mountain wall to collect and dig the ghost spirit grass, Long Zehao and the others walked around the beach by the lake.

It takes a lot of time for Lei Haoyun to collect the Ghost Spirit Grass, first, the number of Ghost Spirit Grass is not large, and the growth location is scattered.

The second is that it is not easy to collect on the mountain wall, especially Long Zehao, what they still want is a live plant, which is the kind that can be transplanted.

And when Lei Haoyun came in last time, he had already checked in detail, and there was no danger in this underground lake, except for a few plants, there was only a small fish in the lake, and nothing else.

In the underground space, although there are photobacteria with a certain light source, and the lake water here is very clear, but the weak light of the photobacteria still cannot shine under the surface of the lake.

However, Lei Haoyun had already gone to the lake to check last time, and there were only some plants such as aquatic plants below, and in addition to this, it was a small fish with long fingers, which was a little transparent, and it was easy to ignore it if it was not careful.

Long Zehao walked around the lake, and found nothing on the beach by the lake, not even a small grass growing on the beach.

Long Zehao, who didn't find it, was about to enter the lake, because Lei Haoyun said that there were aquatic plants growing in the lake, and after Long Zehao drank a bottle of underwater breathing medicine, he took out a lighting stick, and after turning it on, he went into the water and entered the lake.

After coming down, Long Zehao found that this lake was not deep, and the center of the deepest lake was only a dozen meters.

Underwater, Long Zehao also found an inlet into this lake, which was very small, with only a gap, from which a trace of water was injected.

There is water inlet and the water level of the lake has not changed, so there is a similar outlet, the outlet has not been found, and Long Zehao did not look for it in detail, because even if he found it, it would be useless.

However, when Long Zehao was underwater, he still had a little harvest, he found a plant called H. cordata underwater, which belongs to the LV1 level of green quality, and belongs to the new variety of plants determined by the identification technique.

After the harvest, Long Zehao was more motivated to find it.

When Long Zehao was walking under the lake to look for it, he suddenly felt a slight vibration, this vibration only appeared for a moment, and it quickly disappeared, if it wasn't for staying in the water, Long Zehao felt that he might not feel the vibration.

For this small shock, Long Zehao didn't take it to heart, and continued to check the aquatic plants below in the water.

Because Long Zehao made a new discovery, he found that in the direction of the north, the quality of the cordata in the water was slowly improving, although it was still the same green quality.

However, Long Zehao has mastered the field skills of plant planting, and his identification of plants has improved a lot, although their quality is still the same green, but the growth of plants is much better, and the quality of them has also improved a little, but it has not yet reached the qualitative change of upgrading to blue.

There was no change in the attributes, but Long Ze still felt that these cordata plants had changed slightly. This ability is a new ability that Long Zehao mastered after learning domain skills and training under the guidance of his father.

As he moved forward, the quality of Houttuynia cordata improved more and more, and it was about to reach the point of quality upgrading, when a slight vibration came again, which made Long Zehao frown.

It's just a new discovery, which made Long Zehao's mind shift to the top of the cordata again, because Long Zehao found a blue quality of the cordata among these cordata plants.

The appearance of the blue quality H'cordata has not changed much, but it looks stronger and stronger.

Compared with the green quality of the Houttuynia cordata, the blue quality has an extra life attribute, and at the same time, there is also a similar introduction to the ghost spirit grass in the description, which makes Long Zehao feel like he has discovered the secret.

As we continued to advance, the proportion of blue quality in the cordata grass increased, but at this time there was a slight vibration again.

Long Zehao stopped, because the continuous vibration was not normal, even if it was a slight vibration.

Standing there and thinking about it for a while, Long Zehao still decided to move on.

However, moving forward again, Long Zehao sped up, only occasionally stopping to check the Hyantuynia cordata to determine whether the quality of these Heutuynia cordata was still continuing to increase.

As we move forward, the cordata grass grows better and better, and gradually all the cordata grass turns blue quality, but at this time, a stone wall appeared in front of Long Zehao, which means that there is no road ahead.

When I looked up, I found that the stone wall was less than two meters high, and the top of the stone wall was not far from the water, which meant that it was almost to the shore.

looked left and right, confirmed that the approximate width of the stone wall was about thirty meters, and after looking here, he still didn't find anything, and the vibration that came again suggested that Long Zehao needed to hurry ashore.

After collecting two blue quality cordata plants, Long Zehao swam directly towards the lake.

When he swam up, Long Zehao also confirmed on the top of the stone wall, the stone wall was still blue quality H'Hyntuenia cordata, there were no other changes, and even the quality was slightly lower than the bottom of the stone wall.

Long Zehao, who surfaced, observed and found that he was now located diagonally to the right of the passage he entered, and at the same time, he was only more than ten meters away from the shore.

Back on the shore, Long Zehao walked along the lake in the direction of the passage at the entrance.

At this time, Long Mengting and the three of them were all on the side of the passage, and they did not go into the water. Lei Haoyun was still collecting ghost spirit grass on the mountain wall.

"Did you feel the shock just now?" Long Zehao asked Long Mengting when he returned to the entrance of the passage.

Long Mengting looked at Long Zehao with some confusion and asked, "Shock, what shock." ”

"A slight earthquake, a shaking of the earth." Long Zehao said.

"Is there an earthquake, I don't feel it." Long Mengting asked with some surprise when she heard the earthquake.

Because they are now in the underground world, it is very terrifying for an earthquake to occur in the underground world, for the underground world, a major earthquake is like the destruction of the world, even an ordinary earthquake can bring great damage to the underground world.

However, this special plane that only has the underground world, because of the particularity of the world, earthquakes generally rarely occur.

"Nope." Long Zehao listened to Long Mengting's words, he also fell into deep thought, and at the same time, he also recalled that since he came ashore, he had not felt the vibration.

He walked from the place where he went ashore to the side of the passage, and it took a lot of time, according to the vibration that Long Zehao felt underwater, he estimated the frequency of the vibration, so during the time he was walking, there should have been two or three vibrations again, but Long Zehao did not feel the vibration on the way over.

Lei Yingyun on the side was also attracted by the words of the earthquake, she also knew the horror of the earthquake in the underground world, she asked, "Is there really an earthquake?" ”

"I'm not sure, I felt a few slight vibrations when I was underwater just now." Long Zehao is also a little unsure now, whether those tremors are the cause of the earthquake.
