As for the latter, courage without strategy is a major taboo, so Shen Hex is not going in person this time, but rather using the Immortal Dao Divinity Transformation technique to create a manifestation to go in his stead.
By preparing both strategies, he ensures nothing will be left to chance.
And Zhou Qian is well aware of this, which is why he has definitively resolved to forge a good relationship with him.
Do not be deceived by his sincere words earlier, even revealing many heartfelt sentiments; that does not mean he has no intention to kill Shen Hex.
He has prepared for both outcomes: if Shen Hex does not demonstrate sufficient value and threat, their meeting would result not in goodwill but in a deadly enmity.
He would decisively act, use Shen Hex's head to claim merit, and once again walk the path of following the dragon, rather than risk reincarnation.
