I have an infinite lifespan in the city

In a single night, Qin Ming had actually transmigrated to a parallel world!

However, the people in this world only had a lifespan of 30 years!

Lifespan can be traded! If he wanted to survive, he could only earn money to extend his life!

What was that? It could actually exchange one year of its lifespan for luxury cars, mansions, and listed companies?

What was that? One year of lifespan, it could actually be exchanged for a special bodyguard tank aircraft carrier?

Qin Ming originally wanted to be ordinary, but the initial lifespan given by the system was **

What was that? Consuming lifespan can give me black technology? Superpowers?

I’m sorry, but I can really do whatever I want with my life!
