"The letter said that you have to take out the key from the full glass jar to open the door. The prerequisite is that you cannot break the glass jar or dump the glass jar, otherwise you will lose... You cannot use other barbaric methods or techniques to open the door.

"Han Shuoye repeated the content of the letter.

"Using stones, this is something I have known since elementary school!" Han Xier felt that this time it seemed to be particularly simple!

Just use stones to raise the water level and take out the lightweight key in the box!

"Well, it's very simple this time, but I always feel that it's far from that simple!" Gong Yihao also felt strange, looking at the keyhole, is it really that simple?

"Let's go pick up the pebbles first!" Han Xier pulled Ye Zixi to the side to pick up the pebbles.

"You don't think it's that simple, do you?" Han Shuoye looked at Gong Yihao, and when he saw his frown, he knew he was thinking the same thing!

Gong Yihao nodded, "How can it be so simple?" He looked at the glass jar carefully.

These handsome guys and beauties with IQs in the hundreds obviously disdain such a simple question, but how could it be so simple?

"These stones should be enough!" After a visual inspection, Han Xi'er and Ye Zixi poured all the stones into the small opening...

From this moment on, the little clock starts counting!

Ye Zixi reached out and successfully took out the small box. After opening the small box, he took out the key in the box...

"Go and have a look!" Han Shuoye said, Ye Zixi nodded and Gong Yihao tried to use the key to open the door, but the keyhole did not accept the key at all!

"A blind trick! It can't be opened!" Ye Zixi shouted, "Sure enough, it's not that simple!"

Han Xier stared closely at the small box on the ground. The sponge inside absorbed the water, so the key was pressed tightly on the sponge and an outline was drawn out!

But... there is an outline on this end where the key is placed, but why is there an outline on the other end?

"What's going on?" Han Xi'er squatted down and looked at the small box. If the person who got the key was extremely excited but did not open the door, he would completely ignore the small box...

But Han Xier discovered it and started to pay attention...

Time is passing quietly, and Han Xi'er feels more and more the pressure that time puts on the air. The air around him seems to be condensed!

She picked up the box that was stained by mud and water and looked at it carefully...

"Did you find something?" Han Shuoye and others also noticed Han Xier's thoughtful expression.

"Look..." Han Xi'er opened the half of the box, and there was indeed a key lying behind the sponge!

"Key!" Ye Zixi exclaimed, "Go and open the door and try, time, time is getting less and less!" Ye Zixi looked at the time on the small clock, which was ticking less and less!

Han Xier quickly rushed to the door with the key, and finally opened the door with ten seconds left!

The other three people also understood! This time the test is about carefulness and observation! The small clock is frozen at the last ten seconds...
Chapter completed!
