Can life span be exchanged for treasure? I am invincible with infinite life span

Lu Qing'an has special abilities and has lived in the mortal world for many years. He only needs to weed every day to increase his lifespan.

However, no matter how much lifespan he has, it seems to have no other effect except living longer.

Until one day, he was captured in the fairy world and became the "longevity spring" kept by a big family in the fairy world. He was happy.

In the fairy world, there is a pagoda where lifespan can be exchanged for treasures!

The more lifespan is consumed, the higher the level of the treasure you can exchange!

He became rich in the blink of an eye and had countless treasures.

But this did not satisfy him, and he accumulated lifespan wantonly.

Until all the immortal medicines in the fairy world were burned by him, he had no choice but to not let go of the green grass.

As a result, the fairy world was barren overnight...

(In the early stage, he developed in a wretched manner, and invincible in the middle and late stages!)
