This was a killing scheme that needed no premeditation at all. To these four Supreme Ancestors of the Ancient Yue Clan, there was no need for prior communication. In the moment they struck, they already understood each other's thoughts!
Such tacit understanding is something ordinary people wouldn't dare to even dream of. They would rather risk being killed by the Immeasurable Buddha or the Supreme Wuji afterward than not do this!
Chu Mo is terrifying!
He is merely a cultivator of the ancestral realm, yet he already possesses such frightening combat power. Once he enters the Supreme realm, then who besides those two in the entire Tunnel world could be his opponent?
At their level, they don't harbor superficial notions like killing Chu Mo to make them famous or even to become heroes among the ancient clans of the Tunnel world. Of course, they also would not refuse the tangible benefits brought by such fame.
But more so, it is the intense fear from deep within their hearts!
