Niks was so much tensed and was confused that what he should do now. Finally he got an idea. He used his infinity clock to go to the past and tried to stop himself from committing this mistake. But unfortunately he was too late to do so. The timeline was also vanishing along with the universe. Other parallel universes were destroying each other because they were now unstable and the time line related to each universe was intersecting with the other and contradicting the uniqueness of universe. Each universe exists because of the existence of the other one.
On seeing this niks became more worried and finally returned to his house at the present time. He saw that sky was turning greyish and the stars up in the sky were colliding with each other. On the television news was all about the destruction of earth. According to the calculations done by scientists there were still millions of years for the earth to end. But the truth was much bitter. Earth was soon going to end. People were running here and there. Everyone was helpless. They could not go anywhere because the whole universe was at a verge of extinction. Niks knew that it was his mistake. If he would not go to that planet and try to make a protective shield to protect timeline then no such incident would have took place. He was so sad now and was so depressed that he was going to commit a suicide. He went to a mall near his house, went to the roof closed his eyes and jumped from there. But after a few minutes he felt that he was alive. Actually, another niks from one of the parallel universes whose timeline was running 36 years ahead in the future had come to save niks in the present time. He also told niks that the cube in his private planet consisted a tiny undo switch which would work only within 72 hours after a change is done. And till then nearly 60 hours had already passed. Both of them used their infinity clock again to go to that planet. But since the the line of universe was vanishing so it would take nearly 15 hours to reach that planet. Both of them could just hope that they would reach there at right time. On the mid way niks from the parallel universe started to disappear because his universe had been destroyed. Since he was from future so using his technology he overloaded the infinity clock of niks of present time before disappearing. Now niks's speed had become double. The infinity clock protected niks's body so he was safe at this speed even after entering the planet's atmosphere. He quickly went to the cube and he saw that only 2:07 minutes were remaining. He found the tiny switch and finally reversed all the things. Finally all the universes were safe once again and now niks was too happy. He returned home and it was school time. His friends were talking about a movie which had been released recently. The name of the movie was '' our last day on earth''. On hearing this niks laughed and told his friends that no such day would come till the cube is safe. As always his friends thought that niks was crazy and the life continued.....
