Starting with Synthesizing an Interdimensional Gate

Song Ping obtained a system that allows him to combine two identical items into a higher-level item.

At the start, 128 ordinary wooden doors were combined to create a portal to another world.

A wooden stick is too rubbish? No problem, it can be upgraded into a magic staff that can kill a dragon with a single blow.

A tricycle is too low-end? No problem, upgrade it to an aircraft carrier and dominate the stars...

When the cheat code is too overpowered.

It's too easy to become invincible.

Song Ping's only concern was how to have fun!
