The group of blue-feathered birds all rushed to the trunk of the willow tree and split up to dig holes in the middle and upper part of the tree trunk.

Boom!

Boom!

They pecked very hard and worked hard to build a new nest.

At this time, a wicker branch slowly extended from the lowest point towards the neck of a blue-feathered bird, strangling it directly. It made almost no sound, and then one after another, one after another, the blue-feathered birds died silently.

It wasn't until there were only three or four blue-feathered birds left in the group that they finally reacted.

"Chacha!"

The cries of these blue-feathered birds revealed a sound of panic. They instinctively stopped digging holes immediately and wanted to fly away from the willow tree.

How could Su Bai let them go so easily? There were only three or four left, and there was no need to hide them. A wicker volleyed towards the blue-feathered bird that reacted the fastest.

Snapped!

With a crisp sound, the body of the blue-feathered bird fell down, and the other three blue-feathered birds wanted to leave quickly in fear.

Bang! Bang! Bang!

Su Bai controlled the willow stick and struck them three times in quick succession. Suddenly, the three blue-feathered birds fell to the ground powerlessly and were swallowed by them.

"Ding! Get 0.1 evolution points"

"Ding! Get 0.2 evolution points"

"Ding! Get 0.15 evolution points"

"Ding! Get 0.1 evolution points"

...

At this time, after killing the blue-feathered bird, system prompts kept ringing in my ears.

Su Bai found that even if the same blue-feathered bird was killed, the evolution points obtained after killing it were different, and the difference was about 0.1 to 0.2.

It seems that the system's value estimation is very accurate, and the weaker blue-feathered bird can exchange for fewer evolution points. But even so, he also gained 1.45 evolution points this time!

"It is much faster to gain evolution points by devouring creatures than by absorbing natural abilities." Su Bai was a little confused.

You must know that he gained 1.45 evolution points in just half a day. Before, he only accumulated 1 evolution point in a week just by absorbing natural energy.

Su Bai guessed that it was because the living thing itself was a collection of energy, and powerful creatures, such as ferocious beasts, could gain dozens of evolutionary points by swallowing one.

Natural energy is invisible, and 'sunlight' is the fastest way for Su Bai to absorb natural energy. However, his tree body is too thin and the amount of sunlight he can absorb is limited.

But things are different for living things. You can exchange them for as many evolution points as you want. There are risks, but the rewards are also high.

"It supplements by absorbing energy independently and mainly devours other living things!"

After Su Bai thought about this clearly, he knew what to do next, so he naturally gave priority to the quickest way.

.........

a week later.

During Su Bai's period, he killed two flocks of birds, a passing young ferocious beast and many insects, and gained 7.5 evolution points.

And because his level has been upgraded to level 1, his efficiency in absorbing natural energy has become higher. This week, he has gained 3 evolution points by absorbing natural energy.

Although there are not as many evolution points as those obtained by devouring creatures, the current absorption efficiency is three times that of before, which can be regarded as a good risk-free income.

Su Bai brought up the 'Properties Panel'.

[Race: Alienated Willow

Evolution level: Level 1

Lifespan:0.2/20 years

Evolution points: 10.5

Skill: Mildly strengthened wicker]

At this time, the evolution points have been accumulated to 10 points, but they have not been directly upgraded to level 2 as he imagined.

Could it be that the evolution points required to upgrade to level 2 are not 10 points, but more?

Su Bai suddenly thought that he seemed to be confused by some of his own perceptions. He always thought that upgrading was from 1 to 10, and from 10 to 100, but this is not a game, this is reality!

"Want to experiment?"

Su Bai looked at the evolution points column. He could invest evolution points into the improvement of Liu Shu's entire body, but it was unclear whether this would be used to improve the level.

If he could only improve the height of the tree but not the level, wouldn't it be a waste of his efforts this week?

Su Bai's week in the primeval forest even felt like he had spent several months. No one talked to him, he couldn't move, and he couldn't eat. It was somewhat similar to the "vegetative state" mentioned in his previous life, but "

"Vegetative state" is a state of coma without any consciousness.

Su Bai was sober. He had only accumulated 10 evolution points in this week of loneliness, and he didn't want to waste it like this.

But if he didn't put evolution points into the tree body, he wouldn't have any changes and his level wouldn't improve, which made him a little unwilling.

"By the way, you can invest a small amount first."

Su Bai suddenly thought of it, looked at the row of evolution points on the white light screen in front of him, and directly marked out 3 evolution points and threw them towards the "Alienated Willow" in the first row.

In an instant, the willow tree emitted a faint white light, nourishing all parts of the tree. The tree grew longer, and the willow branches scattered around became thicker and longer than before.

Promoted!

Su Bai looked overjoyed and quickly looked at the "attribute panel".

[Race: Alienated Willow

Evolution level: Level 1 (1/10)

Lifespan:0.2/20 years

Evolution points: 7.5

Skill: Mildly strengthened wicker]

Su Bai looked at the evolution level in the second column and saw a note, "one-tenth". In other words, it had just been improved by one-tenth, and it would take nine-tenths to reach level 2.

He calculated that it would take about 30 evolution points!

It was indeed more difficult than I imagined!

Su Bai was not disappointed, after all, nothing in the world was so easy.

"With about two to three weeks of accumulation, you can upgrade to level 2."

Su Bai looked at the surrounding environment. There was no change at all for half a month. Except for trees, there were stones, grass and other things that could not be moved at all.

Occasionally passing birds were killed by him to gain evolution points.

"It's better to raise the wicker a little more first."

Su Bai looked at the wicker that had been strengthened before. Although its lethality was not small, it was only for small animals. If it could be improved, it could fight against some small ferocious beasts.

With a thought in Su Bai's mind, 1 evolution point suddenly turned into a stream of light and merged into the strengthened wicker before, emitting a faint light.

Wait until the light dissipates.

Snapped!

Su Bai directly controlled the air and pumped it. There was a slight wave of air, and the power was obviously increased.

However, it still did not reach the standard he wanted.

This time, he directly crossed over to the 2 evolution point, and the light emitted by the willow suddenly became stronger, and the green light shone in it, and its color was obviously much greener than other willows.

Su Bai controlled the willow stick and threw it out.

boom!

A roaring air wave caused ripples to appear in the air ahead.
Chapter completed!
