May I ask, will future fight will be like people from the future vs in mc's current timeline?
Not really. Time travel is kinda prohibited as there are also time patrollers. Luckily mc will get his hands on the time travel artifact and will follow the enemy to the future after being injured in the fight. A future where martial arts is rare and angels and demons are lurkings.
this is soo interesting. Taking my guess, the three headed dragon's core was taken by the Saber God as well
This is just the tip of the iceberg. In the future natural ki is already gone or shall I say the legendary beast are dead. So to gain immortality one must go back to the past and hunt those beast core. But all this is just the beginning.
