Battle of Tomorrow: Trading with My Daughter from the Future

In 3021, Tianlong Star received a plea for help from the future:

Twenty years from now, Tianlong Star will be attacked by alien creatures and face the threat of extinction.

Li Xuan, a live-in son-in-law, was set up by his sister-in-law and recruited as a warrior to travel to the future and fight monsters.

In the future, vegetation runs wild, oxygen levels have doubled, and temperatures have plummeted.

Ants rule this world, feeding on metal, humans, and mutated creatures.

There are no firearms, no advanced technology, and no way to cook food.

But the world has the most powerful and prestigious armor masters and visualization masters.

What will happen when Li Xuan, who can travel through time and space, meets his future daughter?

What will happen when Li Xuan becomes both an armor master and a visualization master?

What will happen when Li Xuan discovers that the plea for help from the future seems to conceal another motive?

Can he uncover the conspiracy and save his family in both worlds?

Can he build a super-empire spanning the present and the future?
