Seeing that they were still reasonable, Chu Xiongfei's face flashed with satisfaction.
After everyone had almost retreated, he waved to Lu Yitian.
Seeing this, Lu Yitian immediately reacted and hurried forward to protect the monks with him.
Noticing his actions, the monks looked at each other one after another, with doubts flashing across their faces.
There's something strange about them.
Logically speaking, Chu Xiongfei and Li Yutian's cultivation level is much higher than theirs. If they transfer their spiritual power into the iron gate, the speed should be faster.
But why are they still unwilling to use their spiritual power even though they are about to open it?
It’s impossible to be reluctant to part with this bit of spiritual power, right?
Or do they have other ideas, just like their previous master, who also wanted to trap them here?
However, as soon as this idea flashed through their minds, they were dismissed by themselves.
No, that's not right.
They are not such people.
If they were this kind of people, they should have coaxed them from the beginning and done things for them without trying to explain it to them.
Moreover, looking at the serious expressions on their faces, it doesn't seem to be because of this.
Everyone looked at each other and finally gave up their doubts and focused their attention on the iron door.
After gaining hope, those who injected spiritual energy worked even harder.
As layer after layer of spiritual power slowly invaded the iron gate, Chu Xiongfei could hear the cracking sound, becoming more and more loud.
His heart was beating rapidly and the joy on his face could hardly be concealed.
However, apart from that, there was still a trace of worry in his mind.
They remembered clearly when they came before that they passed through at least two tunnels and passed through two doors.
The total length of these two tunnels must be at least one thousand meters.
At first, Chu Xiongfei and the others didn't pay attention, but later he realized that the kilometer was actually going down slowly.
In other words, their current position is at least a thousand meters above the ground.
The moment the iron door was opened, the water that buried the entire roof was bound to hit their room.
Based on the water pressure, the speed of the water flow is enough to wash away all these people.
This is why Chu Xiongfei asked them to hold their breath and hide.
But even so, no one can guarantee whether these people will survive.
Therefore, Chu Xiongfei and Lu Yitian made a decision in their hearts at the same time without even discussing it.
They planned to open the barrier to protect these people the moment the water rushed over.
At least give them some time to relax, and then let them climb up when the water flow is not so strong.
However, Chu Xiongfei and Lu Yitian didn't know how long their barrier could last under such strong water pressure.
It's not clear whether they still have the strength to leave the bottom of the water after all the efforts to block them with barriers.
But no matter what, they cannot give up on these people.
"Click, click, click..."
At this moment, a dense cracking sound suddenly came from the iron door.
