The War of Civilizations

In the year 5032 of the Divine River Era, a once-weak technological civilization suddenly mutated into a mechanical civilization and launched an attack on the magical and cultivation civilizations in the same star system.

Faced with millions of mechs, even the magical and cultivation civilizations, each at the height of their power, could not withstand the onslaught when they joined forces.

Merlin, the magical civilization's only Archmage, cast a forbidden spell at the cost of his own soul. In the end, he still failed to destroy the mechanical civilization's armies, and the alliance between the magical and cultivation civilizations was utterly crushed.

Yuan Yi, an ordinary magic apprentice, not only survived the destruction of his planet, but transmigrated back ten years into the past.

Bearing Master Merlin's hopes, can he save the magical civilization within ten years?
