During the climbing process, debris kept falling down.
Li Yu looked at the thing above blocking the sunlight, which seemed somewhat like a metal plate. Can Tiezi, alone, move it?
So, Li Yu also climbed up from another metal rod.
Dadada
Using both hands and feet, the two of them climbed up step by step.
Li Gang below looked up, using a flashlight to illuminate for them.
...
Finally, the two climbed up, one hand grabbing the metal rod while the other tried to push the metal plate open.
Li Tie exerted all his strength but still couldn't budge the metal plate.
Seeing this, Li Yu said, "Together, I'll count to three, then let's push hard together."
One two three!
Push!
The metal plate moved slightly, some debris fell down, blurring Li Gang's vision below.
Again!
One two three!
Push!
The metal plate shifted a little more to the side.
It seemed that this metal plate must have been moved there by Mr. Wang; otherwise, Mr. Wang couldn't have escaped from here.
