Yu Fei frowned on the spot and looked at the man who was gradually rolling over. He didn't know whether he should tell others about this.

After a while, the last person finally arrived and was pulled to his feet by everyone.

Yu Fei took a step forward and thought again about whether to go back. There was no one on the suspension bridge at this time, but this time, the sense of crisis coming from his sixth sense was very strong, as if telling him that if he went back now, he would definitely die!

This difference stunned Yu Fei. What is the principle? Why is it different from just now?

Just as he was thinking about this problem, the last person started to cross the bridge. That person had just stepped on the bridge, and the sense of crisis quickly decreased and returned to the previous level.

In fact, the previous level has always been there, because as long as Yu Fei does risky things, he will definitely have it.

So it means that when there are people on the bridge, it is better to come over from the opposite side first. In this process, it is safe to go back!

Yu Fei's brain was spinning rapidly. After reading so many books, he suddenly understood the principle of this!

This is something like a one-way valve. If someone from the opposite side goes this way first, the one-way valve will allow passage, so it is safe!

But if everyone comes over and someone wants to turn back, the one-way valve will open, which is dangerous!
