I kidnapped an alien civilization

When the Pajero, a level 4 carbon-based civilization, was preparing to enter the level 5 civilization through the space dimension experiment, an accident happened.
The bodies of all Pajero people are "mysteriously connected" with the body of Li Mo, an ordinary high school student on Earth.
Any damage Li Mo receives will be completely "feedback" to all Pajero people.
Pajero people panic!
Once this earthling comes to the end of his lifespan...the entire Pajero civilization will cease to exist.
