South American rainforests.

After Gu Feng and the old man Tengger used the eggs on the sick mulberry to solve the problem of lunch, they repaired in place for a few minutes and continued to walk south.

As time passed, the light rain over the rainforest gradually stopped.

After the humidity and heat in the rainforest reached a peak at about two o'clock in the afternoon, the humid air that encroached on every inch of space in the rainforest gradually brought an unbearable cold and humidity as the temperature dropped.

After continuing to walk through the rainforest for several hours, the robes of Gu Feng and the old man Tengger were completely soaked with the humid air, revealing patches of dull wet marks.

The old man buried his head in cleaning the rotten root system of a mountain cherry tree, which was infected with tengu nest disease, and the branches and leaves died, and the roots rotted, and the whole tree looked like an elderly man with terminal cancer, as if it was only one step away from death.

In the old era, there was no cure for the tengu nest disease, and the diseased tree could only recover itself by strengthening the root system of the plant, and the old man kept sending green wood breath spiritual power to the healthy roots of the mountain cherry tree while cleaning up the damp roots that had completely rotted and diseased.

This mountain cherry tree is more than five meters in diameter, and its root system is buried deep in the ground, and its roots are intertwined, so it is not easy to clean up.

The old man has been busy for nearly half an hour.

Gu Feng carried the herbs on his back and stood aside, watching the old man's movements seriously.

Clearing the roots of a large tree deep underground requires a wood ability, and as much as he would love to help the old man, he can only choose not to reveal his abilities for some consideration, and stand aside and watch quietly.

The sky in the rainforest tends to darken.

But at five o'clock in the afternoon, the sun was still hanging in the sky, and those slanted rays could no longer bring light to the rainforest.

The darkness of the night had already fallen on the rainforest earlier than anywhere else.

After cleaning up the last rotten root system of the mountain cherry tree buried in the deepest part of the ground, Tengger looked up at the sky in the rainforest, then climbed to the tree and broke off a few freshly sprouted cherry blossom branches, then came down and put the branches into the medicine basket and patted Gu Feng on the shoulder.

"It's getting late, it's time to go home."

"Hmm." Gu Feng nodded.

After hearing Gu Feng's promise, the old man suddenly turned around and ran, and every time his feet borrowed strength from the tree trunk, he would rush out dozens of meters.

In the unusually lush rainforest, the old man walked through as if there was no obstacle, and he walked at a very fast speed, and he was in a crazy posture of running away with all his strength regardless of the medicine basket.

Gu Feng's face showed a look of surprise.

He hasn't been much of an old man in the past two days.

Little did he know that neither his excessively clean clothes, nor the transoceanic food he had brought out, nor the excessively leisurely and comfortable look on his face, had made Tengger feel deeply uneasy.

It was the old man's plan to lure Gu Feng to a place dozens of miles away from the tree doctor town, and then leave quickly while night fell.

Life in the town of Tree Doctor is very happy and happy, and the old man doesn't want to bet on whether Gu Feng who suddenly appears is a good person or a bad person.

The surprise on Gu Feng's face quickly disappeared, he stood in place and smiled, and then chased after the old man.

The plants in the rainforest grew very luxuriantly, and Gu Feng, who followed the old man Tengger to treat injured and diseased trees for a day, did not want to destroy a large number of trees, so he had to learn the old man's movements and bounce between the trunks.

Since Gu Feng's understanding of this rainforest was far inferior to that of the old man, his speed naturally slowed down, and he could only stick a few hundred meters behind the old man, and he couldn't catch up quickly.

After walking through the forest for a few minutes, a faint sense of crisis suddenly appeared in the canopy above Gu Feng, and he reflexively pulled out his right hand and carefully swung a punch, directly cutting the figure of a black shadow in two.

Gu Feng had an excellent control over his strength, and the shadow leopard that suddenly appeared was only half of his body neatly cut off by the strength of his fist, and half of his body was well preserved.

The powerful fist turned the upper half of the Shadow Leopard's body into blood foam, and then struck straight towards the canopy above the tree.

"Boom...... Rumble...... The sound of "boom ......" quickly resounded in the rainforest, and the golden sunset was projected through the neat hollows of the punch.

Gu Feng glanced at the sky on the other side of the hollow, and after putting away half of the corpse of the shadow leopard, he flew out of the hollow and flew straight towards the tree doctor town.

Flying over the canopy of the rainforest is an incomparably stupid choice for people who are not strong enough, but it is very suitable for Gu Feng.

Tengri, who was walking through the forest, looked at a giant flaming red tree not far from him in shock.

The branches and leaves of that giant tree were fiery red, and the air around it was twisted and hot, and it was obviously a rare powerful dryad with fire-based abilities.

Of course, Tengger, who has lived in this rainforest all his life, is no stranger to the dryad, and even has some friendship with it because he has helped him treat it several times for heat fungus.

This is a five-lock realm tree demon king evolved from the fire mulberry tree, and its strength is at the top level in the entire South American rainforest.

However, such a powerful dryad, on its fiery red sturdy trunk, it was neatly pierced by a fist wind hundreds of meters away.

The dryad's painful wails continued to reach the old man's mind through a special path, so that he did not dare to think about the horror in it, so he could only walk through the rain forest as fast as he could.

Half an hour later, Tengger, who was wet with dew in the forest, finally saw the lights of the tree doctor town.

The yellow light at the entrance of the town and the faint sound of talking in the town seemed to give the old man a heart booster, which gradually relaxed his nervous mind.

He stood in the shadow behind a huge tree at the entrance of the town, and focused on projecting his perception into the town, and after carefully perceiving Gu Feng's breath for a few minutes, the old man was really relieved and walked towards the town with a smile.

The rainforest at night is nothing short of hell for the unfamiliar with the surrounding terrain.

In the old man's opinion, no matter how strong the young man was, the darkness of the rainforest was enough to make him lose his way.

As soon as Tengger, who was a little embarrassed, appeared at the entrance of the town, he was surrounded by some residents standing at the entrance of the town.

A strong Orion in the town was bitten by an unknown poisonous snake, all the tree doctors have seen it, and the herbs prescribed and a few injections of snake venom have no effect, fortunately, the bitten Orion is a rare master of the Three Locks Realm in the town, and he has been dead under the snake venom for two hours, and finally waited for Tengger's return.

Due to the critical situation, the residents of the town did not notice the old man's abnormality, but only hurriedly talked about the condition of the hunter.

Surrounded by everyone, Tengger walked towards Orion's house, and soon identified the type of poisonous snake that bit Orion according to everyone's complaints, and immediately thought of the corresponding special herbs.

There are dozens of tree doctors in the town, and each tree doctor has some common herbs in their homes.

After hastily fetching herbs from a tree doctor's house passing by, Tengger went to Orion's house, ground several common herbs evenly, mixed them according to a certain proportion, brewed them with warm water, and then helped Orion who had fallen into a coma to pour them down.

A dose of herbs went down, and the pale man's breathing gradually became even, and his internal organs had been bleeding extensively under the erosion of snake venom, and a few minutes later, the snake venom entered the heart, and even if Tengger's medical skills were ten times higher, he would not be able to return to the sky.

After Tengger stabilized the man's injury, he carefully checked the man's body, he remade a few pairs of detoxifying herbs, and then sat on the side of the man's bed, waiting until the man's face was a little healthy red and the condition was stable, and then he said goodbye and left.

The old man was really tired after a day's tossing, otherwise he would have spent more time in Orion's house.
