To Survive in the Apocalypse, You Build a Mobile Fortress?

(Apocalyptic wasteland + rebirth + system + abilities + half data flow + single female protagonist + mutated creatures) Fang Hui traveled through the wasteland world of Blue Star and became a scavenger. The wasteland is full of various dangers and mutated creatures. Unexpectedly, he was bitten by a mutant rat just after traveling through time. When Fang Hui didn't know where to go, he accidentally met Su Qing and got help. At the same time, the scientific research simulation system is awakened. Kill monsters to obtain scientific research points, and use the scientific research points to strengthen weapons and equipment. When a seemingly ordinary pistol shot a mutated giant dog in the head in Fang Hui's hand, the other survivors were still digging grass roots and eating rats. Faced with the huge mutants that were more than thirty meters high emerging from the underground of the city center, other evolvers had fallen into despair. However, Fang Hui raised the Death Sigh in his hand. The pistol turned into a large sniper in an instant, and Fang Hui held it in his hand. "Have you eaten? If not, shoot me!" As the gun rang out, the upper body of the huge mutant disappeared. Facing the looks of admiration or awe from other evolvers, they were all surprised as to how Fang Hui could achieve this level. Fang Hui said: It is estimated that its appetite is too small, and it can't even eat the equivalent of 10 tons of TNT. It may be starved to death.
