Actually, the instant Lan Bao and company appeared, Ye Yuan was already racking his brains on how to escape.
After he saw Lan Bao's strength, he knew that wanting to bring everyone away was already something impossible.
Ye Yuan was not a foolish person, being fully aware that he was outmatched. If he went on, it would be a certain death.
That was not bravery, but stupidity!
Staying behind to die together with Mei Zhen and the rest was the most stupid choice.
Furthermore . . . if even he was sent inside too, then it would really be hopeless.
As long as he, Ye Yuan, did not die, there would always be a chance to rescue everybody.
Hence, from that time, Ye Yuan already made preparations to escape alone.
Ye Yuan had made the decision long ago. If Mei Zhen, Mo Yuntian, or the rest suffered anything untoward, he would definitely bury the entire Fierce Gale World with them someday!
English equivalent of the title is shooting fish in a barrel meaning an easy prey. I left it as literal translation because it's used later.
