After extracting the bullet fragments lodged inside the Flat-Headed Beast's body, Yu Ziyu did not immediately sprinkle Life Essence.
The power contained in his Life Essence was too potent—at this moment, it could do more harm than good to the Flat-Headed Beast and the Wind Wolves.
Thinking this through, Yu Ziyu shifted his gaze to a patch of ground not far away.
Rumble... rumble...
Countless black roots broke through the earth, emerging from the soil, causing the entire canyon to tremble slightly.
Then, these roots twisted and intertwined like giant serpents, rolling back and forth across the land.
Sometimes they formed a black net, pushing heaps of dirt aside; other times, they lifted huge boulders and tossed them far away with brute force.
Before long, under Yu Ziyu's terrifying power, a circular pit about 20 to 30 meters in diameter and 6 to 7 meters deep was exposed on the ground.
After finishing this, Yu Ziyu turned his attention to a nearby stream.
No, it was more accurate to call it a mountain spring flowing through a low, elongated depression, with rainwater slowly trickling down over the past few days.
Thanks to this, a lake was almost complete.
Smiling to himself, Yu Ziyu used his roots to finish the final redirection of the water.
In just half an hour, a somewhat murky lake fully appeared before him.
"Go on."
Twisting his branches, Yu Ziyu gently placed the Flat-Headed Beast into the lake and then drove the Wind Wolves inside as well.
Before they could climb out, one of his branches broke off, revealing a smooth, cut surface.
A drop of rich Life Essence fell into the water.
Howl, howl, howl...
Amid the low howls, the Wind Wolves and the Flat-Headed Beast quieted down.
The surface of the lake shimmered with a faint glow, enveloping them in a warm, comforting sensation.
...
A white crane spreads its wings with a shriek.
A wild bull wakes with a bellow...
One by one, mutated beasts focused their gaze on the lake not far away.
Yet held back by the moving branches above, most hesitated and chose to stop.
"These are their rewards."
Yu Ziyu chuckled softly watching the hesitant mutated beasts.
Indeed, opening up a lake made the canyon more lively.
Simply by dripping Life Essence into it over time, this lake could become a small spiritual lake.
Such a spiritual lake could nurture most animals within the area.
This made Yu Ziyu think of his main root.
The terrifying root, deeply embedded in the earth, with tendrils spread across the rocks, greedily absorbing the underground spiritual river flowing beneath.
The spiritual river, a stream infused with abundant spiritual energy—
In Yu Ziyu's view, this was an extremely valuable treasure.
How valuable?
Just look at his main root now—only about ten days in, and it had thickened significantly.
Even more shocking was what he saw deep underground—his main root seemed to be breathing, expanding and contracting, gulping down enormous amounts of spiritual energy.
Though this inhalation-exhalation was not very noticeable to his surface form, the willow tree, it acted like a catalyst to his sprawling roots in the earth.
Yu Ziyu could clearly feel his countless roots strengthening continuously, spreading like a net in all directions.
It wouldn't take long before the underground of this 200-300 square meter canyon was completely covered by his roots.
If his "evolution points" were the enhancement of his abilities, then this underground spiritual river was the cornerstone driving his next evolution.
"The underground spiritual river is so useful to me, it must be valuable to other mutated beasts as well."
After some contemplation, Yu Ziyu reached a conclusion.
If he guessed right, this kind of spiritual energy-rich resource would become highly contested in the future.
...
Time flew by—several days passed.
On a certain afternoon, in a mysterious corner of this nation...
Sigh...
An old man sighed, looking at Yan Gaoyuan, who was sitting rigidly upright nearby.
He shook his head, offering comfort:
"Gaoyuan, you worked hard this time."
"Not hard at all."
Yan Gaoyuan responded tersely but let out a muffled grunt.
Then, unable to hold it back, he coughed several times.
When he finally removed his hand from his mouth, a smear of crimson caught the old man's eye.
"Sigh, it seems you've encountered a ruthless opponent."
"Indeed, ruthless."
Yan Gaoyuan recalled that mutated Flat-Headed Beast with the streak of silver fur.
A truly terrifying creature.
It had once been called "the world's most fearless animal,"
and even after mutating, it retained its ferocious spirit.
Wiping the blood from his hand and mouth with a tissue, Yan Gaoyuan began to discuss business.
"Sir, based on the current information, that mountain may have undergone some mutation. Of course, we can't rule out the presence of powerful mutated beasts."
"I see..."
The old man nodded, taking the report Yan Gaoyuan handed him.
"So you said the dense fog there doesn't dissipate and it affects people's mental state?"
"Yes. That's also why I believe mutation has occurred there. Like other mutation zones, there are phenomena that science cannot explain."
"Indeed, mutation is difficult to explain. But since the fog isn't highly dangerous, let's designate that mountain as a Yellow Warning Zone for now. However, keep it under constant surveillance. At the slightest sign of change, immediately upgrade it to a Red Danger Zone."
"A Yellow Warning Zone for focused monitoring?"
Yan Gaoyuan murmured, showing a trace of agreement on his face.
