In fact, Great Qin had never said that they wouldn't allow the diplomatic mission of the ten nations to enter Hangu Pass. They had only set up the trial, and the nine nations could challenge the trial voluntarily.
It was fine if they were unwilling to challenge the trial.
But this was equivalent to giving up the right to host the Ten Nations Martial Arts Tournament.
Of course, even if they didn't challenge the trials, they could still participate in the Ten Nations Martial Arts Tournament. It was just that they couldn't participate as the host.
It was precisely because of this that the current army of Great Qin stationed at Hangu Pass wasn't the true elites of Great Qin, and the general wasn't necessarily a higher-up of Great Qin.
He might not even know the specifics of the nine checkpoints. Even if Zhou Shu obtained the hair of this general, what use would it be?
