Long Zehao and the others were still discussing the matter of the earthquake, and Lei Haoyun had already collected the ghost spirit grass they needed.

Lei Haoyun was directly led by the harpy and landed beside Long Zehao. He took out the collected ghost spirit grass from his body and distributed them to Long Zehao and Long Mengting.

Lei Haoyun also asked at the same time when distributing: "By the way, do you have the plants you want to harvest in the lake?" ”

"There's a plant called Houttuynia cordata, and I dug up two of them." Long Zehao replied, although he dug it by himself, but entering here is also the way led by Lei Haoyun, so he still needs to pay Lei Haoyun a money, and this thing is not worth concealing.

"Hyntuynia cordata, first-order blue quality, right?" Lei Haoyun asked.

Long Zehao was not surprised that Lei Haoyun knew about Heudynia, after all, Lei Haoyun must have entered this underground lake in detail when he came in last time, Long Zehao nodded and responded: "Yes." ”

"Look, the surface of the lake has changed." Lan Yuefang suddenly called.

Because Lan Yuefang didn't need the Ghost Spirit Grass, she didn't pay attention to Long Zehao and them at this time, and after Long Zehao said that he felt a vibration just now, Lan Yuefang had been looking at the surrounding environment, and when the lake surface changed, she directly discovered the situation.

When Long Zehao heard this, he looked towards the lake, and the lake surface, which was originally relatively calm, now had ripples. There are no large creatures in the lake, and there is no current impact, so it is really not normal for there to be waves.

"The water level is going down." Lei Yingyun also spoke.

Similarly, Lei Yingyun was also observing the surrounding environment like Lan Yuefang just now, and she was also the first discoverer of the changes in the lake level.

Hearing this, Long Zehao began to pay attention to the water level of the lake, and after careful observation and comparison, it was determined that the water level was indeed slowly declining, but the decline speed was very full, and it was impossible to see if he didn't pay attention.

Lei Haoyun reacted first and said, "Let's go, let's go to the upper channel platform first." ”

Unsure if this change would be dangerous, Lei Haoyun decided to return to the platform on the mountain wall first.

It's much safer there, and as long as you don't have the ability to fly, even if it's dangerous, it won't affect the platform.

And even if there is danger, as long as he hides in the passage, in the narrow passage, his troops can hold the enemy back.

Once again, he was carried by the harpy and flew onto the small platform, standing on it, he could see more clearly, in the lake, a small whirlpool had appeared at this time, and the water in the lake was slowly flowing away through this small whirlpool.

Long Zehao looked at the location of the whirlpool and found that it was where the blue quality water cordata was found.

After a few people watched for a while, they lost interest, because the water level was falling very slowly, so they only occasionally turned their heads to look at the lake.

Because of the unknown changes, Lei Haoyun also stayed here, he was going to see the new situation, and besides, unknown changes can generally bring great gains, and of course, they may also die in this change.

Lei Haoyun had already sent a few harpy banshees to the front to observe closely.

……

The next morning, when Long Zehao came out of the tent, he found that there was a new change in the lake.

The water level of the lake has dropped a lot, and the originally clear water has become turbid, and it is still the same polluted dark green color.

"Did you find anything?" Long Zehao asked Lei Haoyun, who was sitting on the edge of the platform, staring at the lake.

Lei Haoyun looked up at Long Zehao, turned back and continued to stare at the surface of the lake and said, "The lake water is corroded by undead energy, and the leaky crack below should lead to a place where undead energy is rich. ”

When Long Zehao heard that the path was to a place where the energy of the undead was strong, he was not very interested, after all, the path of the undead was too different from him.

The attributes of the Green Dragon Bloodline Warlock he walked were biased towards the wood attribute, the plant attribute, and the undead attribute was still in a slight opposite state. In that kind of place where the undead energy is strong, it will be suppressed even more.

However, the current Long Ze Haohai has no official employment, and the specific attribute nature has not been opened, so he doesn't have much feeling about these yet.

Time passed in this wait.

"Do you feel the ground shaking?" Long Zehao said with some frowns.

The ground around him was still the same as usual, and no changes could be seen with the naked eye, but Long Zehao felt that the entire ground was shaking slightly.

"You feel that way, too, I thought it was my mistake." After Long Mengting heard Long Zehao's words, she spoke.

"Is the ground shaking, no?" Lei Yingyun looked at Long Zehao and the two of them a little strangely and said.

Long Zehao looked at Lan Yuefang and Lei Haoyun, they all had the same strange expressions, obviously they didn't feel the shaking of the ground on the two pages.

Only he and Long Mengting could feel this, but why could only the two of them feel the shaking of the ground, Long Zehao turned his head to look at Long Mengting, and found that Long Mengting was also looking at him.

The ground shook for more than ten seconds, and when Long Zehao was still confused, Lei Haoyun glanced at Long Zehao and Long Mengting, and then said: "There may have been real shaking just now, but only Long Zehe and Long Mengting noticed it." ”

Seeing that everyone's eyes were focused on him, Lei Haoyun explained: "Just look at the surface of the lake, the whirlpool that has not changed has become bigger now, indicating that the leakage under the lake has become larger." ”

Hearing the changes in the lake, Long Zehao looked over, and it was true that the original whirlpool had become four or five times larger, and the drop in the water level was now almost visible to the naked eye.

The stone wall with blue cordata grass was exposed, and Long Zehao found that the water that disappeared from the whirlpool had entered the stone wall. In front, I could only confirm that the passage should be near the stone wall, and now I can see it completely.

Seeing that there had been no danger, and Lei Haoyun's harpy had not found any enemies, Long Zehao and the others came from the platform above the mountain wall to the bottom again.

Although the surface of the water is only two meters lower, the surface area of the lake has decreased considerably.

When I came to the stone wall, I stood on it and looked down, and found that there was a crack on the stone wall that was half a meter wide and more than a meter wide. The highest part of the crack is half a meter away from the top of the stone wall.

After the water surface descended to the top of the crack, the original whirlpool had disappeared, but a large amount of lake water rushed towards the huge crack, and the raging lake water also prevented Long Zehao and them from going into the water to check.

However, with this huge crack, the water level of the lake should be able to drop below the crack very quickly, and what Long Zehao and they did was wait for a while.
