But when it got light the next morning, Jiang Wan was surprised to find that this test of the oxygen-deprived apocalypse was not the death of plants.
All the plants die during the alternation of harsh winters and extreme heat and cold, but quickly revive with the nourishment of rain.
Because before dawn, a sudden and extremely heavy rainstorm occurred, accompanied by lightning, thunder, and strong winds.
When the wind and rain stopped, all the dead plants came back to life overnight.
All the plants had become truly mutated plants, growing to several times their original size as if they had been given growth hormones.
Even annual herbaceous plants that used to grow small and short are now as tall as a person.
Overnight, some flowering plants burst into full bloom, displaying a riot of colors and vibrant hues.
The whole world has become the domain of plants—no, it has become the domain of plant monsters.
Within the area where Longxiang City is preparing to build the city, all the plants have been cleared away in advance, so there is no threat of mutated plants for the time being.
But Jiang Wan felt that the dangers of this world were not so simple.
So he found Cheng Zhen and sincerely suggested: "In addition to building the city wall, have everyone dig up every inch of land inside the city, leaving no root behind, dig them all up, and then dispose of them properly."
In this sweltering heat, everyone hopes for rain to cool things down.
But at this moment, Jiang Wan was extremely afraid of rain.
Because once the rain nourishes the roots hidden beneath the soil, they absorb enough nutrients and then grow wildly.
In the past, due to the lack of oxygen in the wild, normal plants stopped growing, and some became mutated plants, so frankly, they didn't pose a great threat to humans.
But now, the mutated plants are also starting to grow wildly. They are encroaching on every piece of land where humans live. It is not that the ground beneath buildings is absolutely safe. Every root under every inch of land must be dug up.
Jiang Wan didn't need to explain in detail; Cheng Zhen understood immediately and gave instructions to someone to handle the matter.
As soon as people started digging, shouts of surprise rose and fell: "Holy crap! These are so thick and strong! How did they grow like that?"
"Watch out! They can move!"
"Watch out! Don't let them catch you! They crave blood!"
Cheng Zhen listened to their discussion, standing outside the vermilion city wall, his gaze fixed on the high wall.
What are you thinking?
Long Wanzhi came over. Everyone was in low spirits. It was too hot during the day, so they could only take advantage of the sunset when the sunlight was weak to go out.
Although he didn't specify what it was about, Cheng Zhen understood.
He was silent for a moment, his gaze seemingly piercing through the city wall in front of him: "Let's give them a hint. Whether they believe it or not, and whether they have the ability to survive, is their own business."
Although he said that, he had his own plans in mind.
Cheng Wenshan said that there is an arsenal in Zhusha City. If his intelligence is correct, then the underground arsenal they raided outside the city was not the real arsenal of Zhusha City.
If that's the case, he really can't let the people of Vermilion City be so easily invaded by these plant monsters.
Compared to the already grown giant monster, the mutated roots buried underground are relatively easier to deal with.
Moreover, dealing with it now doesn't require him to expend his own manpower.
"So what are you planning to do?"
Long Wanzhi's feelings towards Zhusha City are also quite complicated. Zhang Hao's ill intentions in the past caused the deaths of many of his citizens, but now, in this oxygen-deprived apocalypse with fewer and fewer humans, they should work together to overcome the current difficulties.
It was because of this idea that he had this conversation with Cheng Zhen.
Cheng Zhen patted his shoulder: "Leave this to me. Don't worry. They are them, and we are us. No matter how long they can survive in this oxygen-deficient apocalypse, let's just consider them as fellow travelers in this world."
After he finished speaking, the two fell silent.
Perhaps knowing how dangerous an oxygen-deprived apocalypse is, or perhaps feeling how insignificant humanity is in the face of a monstrous natural world, they do not wish for a large-scale human death at this moment.
Cheng Zhen found Jiang Wan and explained her thoughts.
She immediately understood: "You want me to pass on a message to Jiang Ling?"
Cheng Zhen nodded. Jiang Ling was her aunt, and if she relayed the message, Jiang Ling would probably be willing to listen.
Moreover, as a botanist herself, her words carry more weight, and she has more experience in the digging and processing of plant roots to share.
Jiang Wan agreed: "I'll go now."
The walls of Zhusha City are very high, but some residents living in high-rise buildings, as well as the city guards on duty on the walls, have seen the changes in the wild.
While Zhang Hao and his group were still in shock, they suddenly heard that Jiang Wan from Longxiang City wanted to see Jiang Ling.
He shifted his gaze slightly, giving her a threatening look: "Go and see them. If they want to come into the city, you absolutely cannot agree!"
Jiang Ling accepted the order and left, but she couldn't guess what Jiang Wan wanted to talk to her about.
When the gates of Vermilion City were opened, she was truly terrified by what she saw outside.
All the plants were taller than her. Logically, such a dense, shady growth of plants should have helped to cool down the sweltering heat, but that wasn't the case. These huge, bizarre, and mutated plants blocked out the air, making it seem as if it had stopped circulating.
Besides being hot, it was also stuffy, and the further you went outside, the stronger this feeling became.
She forced herself to endure the discomfort both physically and mentally, and asked, "I heard you were looking for me. What's up?"
Jiang Wan didn't beat around the bush or engage in polite small talk. She pointed directly to the mutated plants outside and said to her, "All the plants have mutated."
"Yes, I saw it."
Jiang Ling thought of how barren their Vermilion City was and couldn't help but feel secretly pleased. Fortunately, the plants had caused a ruckus before and killed all the other plants.
That's why their Vermilion City wasn't like the wilderness, where almost all of their territory was occupied by mutated plants.
Jiang Wan continued to remind them: "You can't be complacent just because there are no plants. Their roots are underground. As long as there is another rain, they will grow wildly, and then your Vermilion City will become like the wild."
Hearing her say that, Jiang Ling's expression changed drastically, but she forced herself to remain calm: "It just rained last night, these are just your guesses, right?"
Jiang Wan didn't argue with her and said directly, "Go back and dig up the plant roots under the soil and you'll see. Yesterday's rain has already changed them. As long as there is another heavy rain, they will definitely break through the soil and completely take over your territory."
