White Cloud Star Lord proposed to capture a prisoner himself, clearly not intending to go with Lin Chen.
Lin Chen slightly breathed a sigh of relief. Encountering White Cloud Star Lord and lending a hand in a fight was a given, as White Cloud Star Lord had helped Lin Chen greatly before. However, if they traveled together and by luck ended up obtaining the Tao Spirit, who would it belong to?
Turn against each other and fight over the Tao Spirit?
That would be truly disgraceful.
So the best way is to act separately, use one's own means, and leave the outcome to fate.
Moreover, the fact that Lin Chen possesses the Linglong Tower should be kept hidden as much as possible. Let's not mention that the Linglong Tower itself is very sensitive; it also contains the Lord Charm Erosion and even the Qingluan Immortal Monarch that he captured himself.
