Survival in the Deep Sea: I Want to Build a Plant Fortress

[Unlimited streaming + system + survival + science fiction + cool writing] Waking up from his dream, Shan Haochuan appeared on a dilapidated submarine. It's freezing temperatures outside, and there are bloodthirsty beasts and unknown mutants wandering around. However, the biggest crisis is that in seven days, radiation will fill every inch of the planet. If you want to survive, you must repair the submarine and drive it into the deep sea. However, what is different from others is that Shan Haochuan can see the reward items for completing system tasks and obtain the required rewards in a planned way. While others were still worrying about survival, Shan Haochuan had already begun collecting the missing parts of the submarine. While others were just struggling to collect supplies, he was protected by the sacred tree "Purple Spirit". He was already sitting in the submarine, drinking corn soup and humming a tune, and by the way, he formed an alliance with his brothers. This is not only a matter of survival in a crisis-ridden world, but also the road for mankind to reach God.
