With sufficient Spiritual Energy, the next step was leveling up.
It's worth mentioning that Ye Feng's speed of leveling up was very fast now.
In the beginning, it took him one minute to complete a level-up.
But as he evolved continuously, the speed of leveling up was also shortening.
Now that he had broken through to the Second Stage, it only took him 20 seconds to complete a level-up.
In other words, he only needed 20 seconds to absorb one Spirit Point, and when he thought about the animals he had captured, the speed at which they absorbed Spiritual Energy gave him a sense of wonder.
If it weren't for the system's leveling-up function, no matter how massive the Spiritual Energy was, he wouldn't have been able to improve so quickly.
As Ye Feng leveled up, in just 20 seconds, all the roots of the tree increased in length by 10 centimeters.
Yes, after breaking through to the Second Stage, he now added one point each time, and the length of the tree roots increased from the original 20 centimeters to 10 centimeters.
Of course, this was understandable, as previously he only had 101 roots, but after breaking through to the Second Stage, the number of roots doubled.
Spending the same amount of Spiritual Energy on leveling up, it was only natural for the growth in the length of the roots to be halved.
Moreover, the Second Stage's roots were much stronger than those of the First Stage in every respect, and even if the number of roots was the same, they should consume more Spiritual Energy.
The roots grew wildly, and within three and a half minutes, Ye Feng had leveled up 10 times, and the roots of the tree had extended another meter.
At the Second Stage, he needed 40 Evolution Points to break through.
So, just by leveling up, the length of the roots could increase by 40 meters.
At this moment, the length of his roots had increased from the original 150 meters to 190 meters.
At the same time, he also met the requirements for evolution.
"Ding! Please choose a direction for strengthening."
Seeing the system prompt that popped up again, Ye Feng first chose to increase strength.
He had thought it through; with one major stage consisting of four Minor Boundaries, he could strengthen each direction of the tree roots, so he just took turns choosing.
After Ye Feng selected the direction of evolution, he began to grow rapidly once more.
Ten minutes later, the evolution ended, and he glanced at the system panel.
Host: Ye Feng (World Tree)
Tree Body Height: 45 meters
Trunk Width: 2.25 meters
Root Length: 210 meters
Realm: Middle of the Second Order
Evolution Points: 0/40 points
Special Ability: Devour, Capture
Spirit Point: 38/450 points
Bioenergy: 150/450 points
Looking at the updated system panel, Ye Feng couldn't help but smile; the length of the roots had finally broken through 200 meters.
Compared to the day before, it had increased tenfold.
And the strength of each root had surged, from the original 100 jin, it increased to 200 jin.
All 202 roots combined, the strength he could burst out instantaneously, could reach a terrifying 20 tons now.
"Hmm! I should have the strength to defend myself," Ye Feng said contentedly as he swayed the roots.
However, he glanced at the height of the tree body and couldn't help showing a look of concern on his face.
His height had reached 45 meters, and there was no doubt that in this valley, he was now ranked second.
And with the next evolution, he would inevitably become the first.
"If I keep evolving like this, I really won't be able to hide at all!" Ye Feng was a bit troubled.
Indeed, there were more than a dozen Unusual Trees in this valley that grew very quickly, but they only grew about 1 meter at most in a day, which was far from comparable to him.
"Sigh~"
Ye Feng let out a soft sigh and then began... allocating points.
He had no choice but to do so, for being too weak meant he feared not only human research but also being killed by other Mutated Animals, so he could only rely on point allocation to get by.
Feeling the rapid growth of his roots, Ye Feng's originally somewhat gloomy mood once again became cheerful.
In the blink of an eye, two hours had passed.
Ye Feng glanced at the system panel, and he had gained another 10 Evolution Points.
This was even given that he hadn't been focusing on allocating points, but rather using more Spiritual Energy to cultivate his subordinates.
And now, after his great sacrifice, he finally saw results.
The King Cobra, a major consumer of spiritual energy, had absorbed close to 50 Spirit Points from Ye Feng and had finally begun its breakthrough.
Ye Feng carefully observed the other's breakthrough process, which took a full half-hour to complete the evolution.
The evolved King Cobra grew another meter in length, and with the previous size increase from devouring Spiritual Energy, it now measured 6.5 meters long.
The current King Cobra was definitely a top-tier dangerous species.
And this was just a Minor Boundary breakthrough. After the breakthrough, the King Cobra's Realm had reached the First Order Peak, and he was somewhat excited about the change that would come when it broke through to the Second Stage.
He estimated that by then, its length would reach more than 10 meters.
At that time, he could give the order for the King Cobra to seek revenge on that Mutated Wild Boar.
At the same time, he turned his gaze to his other subordinates, his face showing a hint of anticipation.
Although the other animals couldn't compare to the King Cobra, as long as their Realm increased, their Combat Power would certainly be considerable.
Especially that Mutated Mouse, which was the highest Realm among his Mutated Animal subordinates when captured, already at the First Order Peak.
And now, it had Devoured 15 Spirit Points from him over time.
Given its size, it was probably not far from a breakthrough.
After filling each subordinate with Spiritual Energy, Ye Feng once again sent them off to hunt.
This time, Ye Feng received a pleasant surprise.
The King Cobra actually dragged back a Mutated Buffalo.
As is well known, the larger the creature, the lower the chance of mutation; but similarly, the stronger they become after mutating.
A Mutated Wild Boar, once grown, can overturn a bus with just two or three charges.
A buffalo with better initial conditions than a wild boar can only be imagined in terms of its growth potential.
Under the same Realm, it would definitely be stronger than a wild boar.
Ye Feng looked at the Mutated Buffalo, which was obviously a size larger than a normal buffalo, clearly having just mutated.
But even so, it still managed to wound the King Cobra.
This scene made Ye Feng even more expectant.
When the King Cobra dragged the buffalo into his territory, he extended 50 tree roots and easily lifted the buffalo, weighing at least a ton.
The Mutated Buffalo, still struggling desperately, seemed petrified at that moment, not daring to move.
The Capturing process that followed was rather smooth; the opponent's will to resist was not strong, and after successfully being Captured, the Loyalty astonishingly reached 75%.
This was definitely considered high, even to the point of surprising Ye Feng.
He knew that when he had Captured the King Cobra, its initial Loyalty was only 65%.
"Could it be because buffalos, being herbivorous, naturally have milder temperaments, making them especially easy to tame?" Ye Feng speculated.
Next came infusing the creature with Spiritual Energy.
The Mutated Buffalo was able to absorb 20 Spirit Points in one go, instantly becoming the highest among all his subordinates.
Although the consumption was a bit high, Ye Feng didn't care at all, for the more Spiritual Energy absorbed, the greater the potential for the future.
Then, Ye Feng went about his business of harvesting Spiritual Energy and then allocating points.
And the King Cobra's breakthrough seemed like a signal; in the following hours, the rest of the Mutated Animals began breaking through in succession.
