The Sacred Tree of the Country: My Sister Handed Me over to the Country at the Beginning

Traveling through a parallel world, the Yulin tree that died in the final battle between humans and alien beasts was reborn and returned to three years ago when the spiritual energy was revived! The spiritual energy recovery hasn't started yet, the strange beast hasn't appeared yet, and my sister is still dead... There is still a chance for everything! I was just an ordinary person in my previous life, but I didn't expect to be reborn and awaken the "Sacred Tree System"! As long as you absorb energy, you can become infinitely stronger! Thinking of the tragic defeat of mankind before rebirth, Yulinshu made a decision... He wants to hand himself over to the country!
