Reasons

Ye Chen naturally had his reasons for refusing. 

The young lady of the Beigong family had a high status, and thus likely had many Divine King realm guards and Primordial Chaos realm subordinates.

In that case, why did she try to save him?

Was she really discussing the Dao with him, or was she trying to steal something from him?

Nirvana Dao?

Ye Chen knew that the Nirvana Dao was extremely powerful, and that very few cultivators could cultivate it. Furthermore, Great Daos could be stripped away. Who knew whether the other party was coveting his Nirvana Dao? After all, he had never met Beigong Ziyu before, so he had no idea what kind of person she was.

"Ahem, Little Brother, don't worry, we won't harm you."

"This time, if it weren't for us, you would have already died!"

Wang Qi walked over slowly with a smile on his face.
