"Whew! It's still good outside air! ”

The cool atmosphere of the night made Lin Yu, who walked out of the gym, feel refreshed, and when he looked back at the neon sign of the gym in the underground world, he couldn't help but smile.

"I've been a part-time fighter in the underground world for a year, and although my evolution level has not improved, my actual combat ability has greatly increased. And with the money earned, I bought enough genetic evolution liquid for Xiao Tao and Xiao Xuan, and their strength improved very quickly, and they have already surpassed my big brother. ”

Lin Yu only worked part-time as a boxer in the Underground World Boxing Gym, and he is still a senior at Linji Middle School. And his younger brother Lin Tao and sister Lin Xiaoxuan have a very high evolutionary talent, and they are both genius students in the school.

Although Lin Yu's talent is not too high, it is not weak either. The reason why he worked so hard and was only a fourth-level evolutionary apprentice was mainly because all of his savings were basically used for his younger siblings, and he himself had never used a genetic evolution liquid.

Genetic evolution fluid is an indispensable thing for evolutionists, which can not only speed up the evolution of evolutionists, but also increase physical fitness.

"Genetic evolution fluid is a good thing, but alas!" Lin Yu sighed softly and sped west along the road.

The asphalt road has cracked, and the potholed pavement is uneven. The weeds on both sides of the road have also evolved, reaching the height of a man, and looking dark and ghostly in the darkness of the night. The lampposts were covered with green vines, and the flickering lights seemed weak. A fresh breeze blew, and the leaves the size of a basin fluttered in the wind, causing rats, bigger than cats, to scurry around and hurry towards the sewers.

Although Lin Yu was in pain, his speed was still fast, and he had already reached the level of 100 meters and 8 seconds, and he ran like a gust of wind.

The underground world boxing gym is in the east of Linji City, which is where the wealthier people live, but Lin Yu's home is in the west of Linji City, which is a hundred miles away, and it takes about an hour for Lin Yu to run all the way.

When Lin Yu ran for dozens of miles, his footsteps suddenly stopped. In front of it appeared a dense forest of vines, huge trees, and the song of unknown birds sounded from time to time.

Lin Yu was not worried about his safety, Linji City was more than one hundred and fifty miles in circumference, and there were many woods in it, and he didn't know how to go. But the evolutionary monsters that threatened humans have long since been cleared, and only some herbivores and other animals remain.

Lin Yu looked around, and after making sure that there was no one, he rushed towards the depths of the woods.

Lin Yu flashed around, grabbed the vines in the woods and swung inward like a monkey, extremely agile. It wasn't until they had crossed the Riches that they stopped on a low hill.

The low mountain is only a few people tall, but it seems very large. Rocks protrude and weeds are everywhere, and an old tree stands on top of it. The old tree is as thick as a grinding plate, but it is not high, more than three feet. Compared with other giant trees, which are often dozens of feet high, they can be called small.

But the strange thing is that there are no trees in the dozens of feet around the low mountain, which is extremely strange.

"Brother Tree! Here I go again! Lin Yu touched the old tree with protruding tendons, as if he was an old friend, and spoke.

If there is any creature in Rinzai City that has not evolved, it is this old tree. According to the old people in the city, this old tree has existed in the 21st century, and its appearance is the same as it is now, and it was still a major sight in Rinzai City at that time.

Moreover, along with the old tree, there is a distant legend.

It is said that once upon a time, there were nine old trees on the low mountain, but eight of them became refined and fled. Eventually, even the old tree had become a fine tree, and when it was about to flee, a wooden nail fell from the sky and nailed it alive there, never to leave. (PS: In my hometown, there is indeed such an old tree and legend!) ）

Everyone scoffed at this legend, thinking it was just a gimmick. Then the world changed, the original small trees have been towering like clouds, but this old tree is still safe and sound, although the middle has attracted the attention of some well-intentioned people, but after research, there is no trace of discovery, and it is gradually forgotten.

Lin Yu only discovered the strangeness of the old tree in an accident, that is, as long as he lies under the tree at night to sleep and rest, the healing speed of the wound will be several times that of usual, which is also a secret of Lin Yu, a secret that can ensure that he fights in the gym without fear of causing muscle damage.

Pulling out a cigarette and putting it in his mouth, Lin Yu sat cross-legged on the ground, leaning his back against the old tree.

"Smack!"

A little scarlet lit up in the night, flickering in and out.

Lin Yu's eyes closed slightly, and a faint smoke ring spit out from his mouth, and his body fell into a sense of extreme comfort. This feeling made his spirit extremely relaxed, and the wound was a little itchy and numb, and Lin Yu enjoyed this feeling very much.

However, Lin Yu, who closed his eyes, did not notice that the clear night sky in the sky was gradually darkening, and the stars were also obscured, as if a black curtain covered the entire sky.

"Da!"

There was a faint sound, the cigarette was extinguished, and the butt fell down his fingers. However, no one could have imagined that this faint, almost inaudible sound would be followed by a series of strange reactions.

The crown of the old tree suddenly lit up with an emerald green light curtain, which was cylindrical, wrapping the entire tree and the forest.

At the moment when the light curtain was generated, a gorgeous silver snake flashed down from the sky and descended straight towards the old tree. Without the slightest warning, the shining silver serpent was long and thick, and seemed to split the canopy in two.

"Boom!"

"Click!"

The thunder was rolling, and it was immediately followed by the silver snake. The emerald green light curtain shattered in an instant under the silver snake, slashing straight above the old tree.

Lin Yu, who was almost asleep, only felt that he was hit by a strong force, and his body flew up instantly, and his whole body was paralyzed like an overcurrent.

"What's going on!" Lin Yu was so angry that he couldn't have imagined that he just wanted to sleep and cause such a big movement. Ignoring the pain in his body, he struggled to open his eyes and see.

I saw that the old tree was full of fire at this time, and the body of the tree was also full of cracks. The sky roared, silver snakes scurried, and several bolts of lightning suddenly fell.

"I'm X, it's thundering!"

Lin Yu only had time to scream, and the lightning had already split the entire tree in two, and then a bolt of lightning passed through the tree and slashed at Lin Yu alive.

Lin Yu only smelled a scorching smell, and he instantly passed out.

"Boom!"

The thunder in the sky was still roaring, as if angry, like a demonstration, and it took more than ten minutes to stop, and the sky began to rain.

The fire on the corpse of the old tree was instantly extinguished by the rain, and the whole low mountain seemed to be plunged into darkness again. Suddenly, a faint emerald green light emanated from the roots of the old tree. The light is delicate and the smell is extremely fresh.

"Bang la la"

At the moment of light, all the towering trees in a radius of miles around the low mountain rose up without wind, and the sound of the leaves flapping resounded throughout the forest. The sound of the syllables was strange, as if it was afraid of the unknown creature that was about to appear, and as if it was happy to welcome the return of their king.

"Sasha!"

The main body of the light surfaced to the ground, but it was a small sapling. The sapling was just over a foot tall and bare, like a small stick, but it had three white roots at its roots. These three roots are about two feet long, and instead of taking root in the ground, they are like tentacles, swinging in all directions, driving the entire body of the tree to move forward in a leisurely manner.

The little sapling seems to want to practice its mobility, swinging left and right a few times. Suddenly, one of its tendrils touched Lin Yu, who had passed out, and their bodies froze suddenly, and then trembled violently.
