After the zombie clones repeatedly infused the climbing vines, the natural energy was purified again and again.

Fang Heng then tested the purified natural energy effect.

The purified natural energy has slightly better effects than ordinary energy.

Overall, there are still no big changes.

So purification has to do with the flow of natural energy?

Fang Heng frowned and simply stopped sensing, leaving the zombie clones to continue leveling up and gaining experience. He began to search carefully along every wall of the villa to find where the natural energy had decreased.

I checked in sequence, starting from the lobby to the second floor, and then from the second floor to the basement.

found it!

After spending a full hour, Fang Heng finally made a discovery.

At the end of the walkway outside the basement on the second floor.

A small amount of natural energy is constantly spilling out from the end of the walkway.

Very strange.

Most areas of the entire villa are covered with vines, but this wall is clean and empty.

What's even more strange is that only the natural energy that has been purified hundreds of times will leak out toward the exit without leaving any trace.

Fang Heng touched his chin, and his first reaction was to go over and block the exit.

But soon I felt something was wrong.

Natural energy is more like being attracted to it.

And the attraction is very small.

It seems to be related to the concentration of natural smell in the whole room.

The higher the concentration, the faster the wall will absorb it.

Until a certain equilibrium is reached, the wall stops absorbing.

If he hadn't stood here and observed carefully, and the entire room was filled with natural energy due to leveling, and the concentration was high enough, the wall would probably not have triggered the absorption effect, and he would not have noticed anything strange about the wall.

"Is there something else hidden inside?"

Fang Heng touched his chin.

He couldn't help but think of what Ruan Ziying had mentioned to him before.

A researcher of natural science once lived in this villa.

possible!

Maybe it’s a mission!

Fang Heng had some guesses in his mind. He took a small step back, raised his fist and punched the wall in front of him.

"winter!

"

The fist hit the solid wall hard!

The wall made a crashing sound, then trembled slightly, and several cracks and a fist mark suddenly appeared.

If there were outsiders present at this time, they would definitely think that Fang Heng was crazy.

That's Adoma Cervantes!

The master who wrote the masterpiece of natural science "General Theory of Nature"!

Was her home forcibly demolished like this?

Fang Heng didn't know this. He looked at the wall and felt even more confused.

Judging from the feedback from this punch, the wall is definitely solid.

He didn't have any hope of finding treasures or anything behind the wall. He just thought that he could get back the overflowing natural energy and not disturb him to continue leveling up.

He worked hard at night to collect energy, but ended up with a rice bug in his house?

See what's inside!

Fang Heng narrowed his eyes, slowly stepped back, stretched out his hand and pointed at the wall.

Behind, the zombie clones followed Fang Heng's instructions and took out hammers and shovels one by one.

"dig!"

"Dong! Dongdong!

"

Late at night, the house was filled with the sounds of banging and digging.

Soon, a hole was dug into the wall by zombie clones.

continue!

Fang Heng sensed the flow of natural energy and controlled the zombie clones to continue digging deeper.

"boom!

!”

A passage more than five meters long was excavated behind the wall, and a wall in front fell down with a bang.

what is that?

A hidden room?

Following the excavated passage and entering the room hidden behind the wall, Fang Heng frowned.

A large room of about 100 square meters.

There is a large piece of mud beneath your feet.

There is a tree planted in the center of the room.

The tree is not very tall, and its leaves are pale purple strips. It is only a little over three meters tall, but it is extremely strong. Visually, it would take more than thirty people to gather around it to hug it.

The remaining magic circle can be seen on the broken wall.

It seems that natural energy is absorbed into this place through the action of the magic circle.

So, that tree?

Fang Heng couldn't help but step forward and carefully observe the trees in the center.

"Is this what it is?"

Trees are constantly absorbing the pure natural energy pouring in from outside.

Since it's easy to find the source, just destroy it directly, and then the closed leveling loop will be completed.

etc!

Fang Heng was about to take action when his heart suddenly moved.

Could it be that this thing is the S-level plant he is looking for?

Fang Heng thought for a while and couldn't help but curl his lips.

probably not.

Mo Jiawei didn't follow him this time, so his luck wouldn't be so good.

Still have to try.

What if?

Thinking about it, Fang Heng stretched out his hand and tried to press it on the plant.

Game prompts appeared on the retina.

[Tip: Players discover unknown plants].

[Tip: Please try to upgrade your natural science level to get more plant-related information].

[Tip: The player has mastered basic mysticism and elementary natural science, and the player meets the initial ‘absorption’ conditions].

[Tip: Players can choose to absorb the natural energy in unknown trees into skills - basic natural science experience points].

[Tip: Affected by the current physique, attributes, status, skills, etc., the estimated conversion ratio is approximately: 1800:1].

Huh!

Absorb energy?

Seeing this game prompt, Fang Heng couldn't help but feel his heart skip a beat.

Is there such a good thing?

Suck it!
