"Okay." Su Yi did not object.
Then, the old man with the bark explained the situation.
The Iron Tower Strong Man and others walked to the edge of the pond to observe. Su Yi also took the opportunity to use the [Eye of Illusion] to watch it again.
Ten minutes later, everyone returned to their original place, their faces looking unhappy.
Even Su Yi's expression became a little solemn.
Because they didn't notice any clues.
If you can’t find the entrance, you won’t be able to enter the next level, and it will be impossible to find the treasure.
"How about we just go into a pool of water and give it a try?" suggested the burly man.
"Are you stupid?" the fat man said unhappily, "If you choose the wrong entrance, you will be doomed to eternity. You know that."
The tower-like man said unconvincedly, "Then what do you say we should do? Should we keep waiting? Or should we go back the same way?"
"Both of you shut up." The old man with bark face gloomily shouted.
It's already this late and these two guys still have the mind to quarrel. It's really infuriating!
The burly man and the fat man suddenly became quiet.
Su Yi seemed not to have heard the quarrel. He pondered for a while, then turned to the [Intelligent Tank] and asked, "No. 2, did you find anything?"
[Smart Tank] said: "I think the most likely problem is the water quality."
Su Yi asked in confusion: "How could the water quality be different?"
He even used the [Eye of Delusion]. If there was a problem, he should have discovered it long ago.
[Intelligent Tank] explained: "The water in the pool may look the same, but it may weigh differently."
"That makes sense." Su Yi's eyes lit up.
Some liquids look similar and cannot be distinguished by the naked eye.
But their density is different, which leads to different weights.
And if the water in one pool has a different weight than the other six, doesn't that mean there is a difference?
Thinking of this, Su Yi quickly took out seven empty mineral water bottles and filled each pool with one.
Everyone was stunned and didn't know what Su Yi was doing.
But no one interrupted.
At this time, Su Yi took the mineral water bottles filled with water and weighed them one by one, and indeed found the difference.
One of the mineral water bottles weighs at least twice as much as the others.
"I found the entrance." Su Yi laughed.
"ah?"
Everyone was confused.
What's going on? Just fill it with water and you know where to put it?
Su Yi didn't play any mystery and gave a simple explanation.
After hearing this, everyone understood.
"Okay, let's not waste time. When I enter the pool later, you must follow me closely." Su Yi reminded.
There are annotations in the tips, saying that the pond is interconnected and if you go in the wrong direction you will get lost.
"Don't worry, there will be no problem." The old man with bark nodded.
"Well, let's do it."
Su Yi stopped talking, took a deep breath, and walked straight into the pool.
If you want to pass through the pool of water to reach the third level, you have to cross a distance of more than one hundred meters. It would be difficult to pass without holding your breath.
The water in the pool was icy cold, and Su Yi swam down quickly after entering it.
According to the instructions, you must first dive ten meters, find a cave entrance, and then continue diving through this cave entrance.
It was pitch black under the pool and it was impossible to tell the direction.
For this reason, Su Yi could only take the [Smart Combat Vehicle] and use it as a high-intensity flashlight.
