In fact, what Zhao Yu said was true. The reason why he insisted on joining the operation was not because he wanted to be a hero, but because he had no other choice.
This was because, according to the hexagram, the trip to the Boneya Valley would be extremely dangerous. The mutated Qiankun hexagram was not a joke. It was possible that the danger this time was even greater than that of the wondrous trace Island.
So, Zhao Yu could have said "No." As long as he followed Li Jing's suggestion and stayed in the base to command from a distance, he could at least be safe.
However, if he did that, he would not only be delaying the points and items he had wagered, but also the Secret Service team members who had risked their lives to enter the Hayla Valley!
According to Zhao Yu's analysis, if his guess was correct, the key to the change of heaven and earth hexagram should be in the Shiya Valley.
