The third Prince had been completely crippled. It was his first time leading an Army to war, and he had suffered such a huge blow. He had completely lost the ability to command the Army to fight.
Of course, the generals of the God race knew this. In order to not let their soldiers die in vain and for the safety of the third Prince, they had to ask Yun Tianlei to command the battle. Therefore, except for the first few attacks on the defensive line at Mount aklaya, Yun Tianlei was the commander of the rest of the battles.
Although Yun Tianlei's token had been taken away by the third Prince and he was not allowed to lead the Army, the Protoss were still very clear about his ability. Therefore, after the third Prince was crippled, they had no choice but to ask Yun Tianlei to lead the Army.
However, they didn't know that Yun Tianlei had suffered as much as the third Prince. He was on the verge of collapse.
