In this way, this world gets enveloped within his world range. As long as he remains silent, others will find it almost impossible to ascertain the situation of this world. By sealing the surrounding worlds, it becomes difficult for them to bypass those worlds and directly enter this one. Earth's random crossing methods have certain restrictions and patterns too.
After capturing this world, you can just find a random excuse.
This world has no alliance with other top-tier worlds, so excuses are easy to find. Being dealt with becomes a fact, and other worlds still won't unite against us since we have our reasons.
As long as there are limits to actions, they can't go all out recklessly, as no one really wants to die.
