Several miraculous plants came from the Treant Territory.
Before Su Mo left the territory and entered the Ten Thousand Mile Mountains, he had personally cultivated several plants in the greenhouse and atop Fruit Tree Mountain. He had also entrusted all the remaining seeds to Su Chan for safekeeping.
According to plan, if he failed to return on time, Su Chan would plant these seeds in batches after winter ended.
That would maximize the territory's chances of getting off to a good start.
However, things had not gone according to plan.
After arriving eight years later, Su Mo had not seen a single one of those miraculous plants. There were no similar items circulating on the market, either.
At first, he had thought it was because of the terrifying earthquake during Wasteland Year Four.
But now, Su Mo understood.
With the dense fog lasting half a year, even if he had been there, it would have been difficult to preserve those plants.
The sun never appeared, and even with artificial light supplied every day, the environmental changes brought by the fog would have been enough to kill all those fragile miraculous plants.
"Could the Treants' extinction have been caused by this as well?"
Those Treants, who had taken root beside the territory and relied on their powerful plants to become virtually invincible defenders, had also vanished without a trace by the eighth year.
After reading a full page of Zheng Shi Guang's description of the fog's dangers, Su Mo formed some vague suspicions.
The various disasters presented by the game truly refreshed humanity's understanding of disasters time and time again.
They were not direct celestial changes, nor were they immediately lethal physical disasters.
This kind of persistent climate was like a slow-acting poison. The longer it lasted, the deadlier it became.
