The tunnel formed by the vortex in the sky was a path Su Ming had opened so that the boy and others could send out their legacy items. Besides them, they could not send in anything else, like their Nascent Divinities.
Since greed could never be satiated, cultivators like the purple-robed old man, who took the risk, were always present. Since they were all bound to die hundreds of years later, then he might as well step into the world that may or may not exist.
But he was worried that Su Ming would not allow this, which was why he had decided to risk trying to deceive him. In truth, Su Ming had long since noticed it, which was why he had said his words earlier, but he had not done anything to bring about the death of the purple-robed old man's Nascent Divinity. The man had been destroyed simply because he could not withstand the mighty pressure in the tunnel.
