'Peter, over here!' Hermes shouted.
Peter jumped into the submarine through the hatch. But it was not over. The war between humanity and the irregular monsters had not been finished. Slowly but surely, humanity was facing extinction.
'Hermes, I need you to know one thing.' Peter whispered.
'Peter, shut up, will you? How the heck did that creature survive? I thought...,' Hermes did not continue.
'We failed, Hermes. Everyone in my batch was wiped out. None survived, even in our protection base. We were attacked, and I barely survived.' Peter sighed.
Hermes knew what should be done at this point, and Peter was suggesting the action. Despite the apocalypse they are facing, Hermes did not want to perform the action.
'Hermes, I know you did not want to do this, but you have to. It's the only choice we can make. We don't have much time; you know that.' Peter revealed the machinery hidden under the cloak.
'Peter, I can't do this. Even if I activate this machine and go back to the past, I can't change anything. What will I do if I go back to the past? Enjoy some more time to live? Plus, we don't even have the power supply to activate this machine. You know, how the heck are we going to use this anyway?' Hermes slammed the wall.
It was not long until the creature outside the hatch noticed the sound. The submarine started to shake, and the hatch started trembling.
'Hermes, you know how to activate this! The power supply...You can use my core. I'm an augmented battle machine, after all. Hermes, you are humanity's last hope!' Peter exclaimed out of frustration.
Right at that moment, the hatch started to open.
'What the... Hermes, you better get my core if you don't want that creature to get it first!' Peter shouted.
With that being Peter's last words, Peter ran to Hermes, picked out a knife, and cut his own chest apart.
'Stop it! You are killing yourself!' Hermes cried out.
'Save humanity; then we will meet again..' Peter said his last words and stopped moving.
'Shit..shit...shit! What the f**k is going on here!' Hermes knelt and sobbed.
But there was no time for sympathetic reactions. Hermes grabbed the energy core and disconnected it from Peter. As Hermes darted to the teleporting machinery, the hatch was lifted.
's**t, what the heck does that monster have in mind!' Hermes quickly activated the machine.
'Year 2021 to Year 2020, initiate teleportation.' Hermes commanded the machinery with his voice.
Year 2021 to Year 2020, initiating teleportation. Teleportation activated. Launching in 10, 9, 8, 7, 6, 5, 4, 3, 2...
It was then. The entire top part of the submarine was fallen apart. In the last two seconds of the machinery loading, Hermes saw something that he should not have. The irregular creature slowly scanned over Hermes and quickly reached its tongue toward Peter. In a second, Peter was gone. When the creature reached its tongue toward Hermes for the second time, Hermes escaped.
Year 2021 to Year 2020, teleportation success.
Year 2021, none of humanity was left on Earth; humanity was extinct.
