In his memory, he clearly recalled that the Tianguang in Yong's hand had been cranked up to its maximum output, amplifying its power but requiring the user to pay a corresponding price!
The shot that Yong fired earlier in the car had overwhelmed his physical endurance, leaving him barely conscious. When he awoke, the three of them were practically buried in the dirt. Their exoskeletal battle suits showed varying degrees of damage, and the wreckage of the monstrous off-road vehicle was a testament to how dire the situation must have been.
Even if you gave it the benefit of the doubt, the recoil from that single laser fired at Tianguang's maximum output didn't kill Yong outright. But it was also impossible for him to appear now with no visible injuries at all!
