By giving up the advantage of having an extra life, Wu You created a local numerical advantage. Wu You's choice was a gamble. If he failed, losing an extra life might not be the worst that could happen. If a worse situation occurred, such as the two meeting under the influence of spacetime force, it would backfire. He won the gamble.
The reason Wu You made such a judgment was mainly because his control over Time far surpassed most actors. Even Pu'er himself might not be able to reach this level. Another reason is that this was in Mirror City, just as the Wu You on the transport ship and the Wu You in deep space were forcibly separated, the Mirror World could achieve the same effect.
Time is still passing.
