Pulling Threads and Eroding Cocoons

My future self is coming to kill me. On the day the college entrance examination ended, Chen Yu's world cracked open. On the other side of the seam is the battlefield where gods fight, the upside-down black forest, and a five-headed snake god nailed to the ground; on the other side of the seam is the girl he has been secretly in love with for three years, and the ordinary life he can never go back to. Someone told him: Your birth is a plan, and someone told him: Your death is also a plan. But when Chen Yu really sees that "future self", all the answers are unimportant. That person was stronger and more desperate than him. The person shed tears and raised the weapon, aiming at his heart. He moved forward with hope, but found that the world was hopeless. He would lose everything, his lover, his family, his most beloved senior brother, his best friend... When he stood on top of the world and was powerful enough to cut off cause and effect, would he still choose to kill his past self?
