Standing in this ancient tree hole that has changed greatly, recalling the strange scene he experienced before, Rao is Lu Chen has always been calm and composed, and he secretly felt a little chill in his heart.

At the same time, he also had a bit of vigilance in his heart, from the battle of the Barren Valley until now, this divine tree seed has been integrated with him, and he has been with him for more than ten years, and he has almost completely regarded it as a part of his body.

He went in and out of this tree hole as if he was going in and out of the house, everything seemed so natural, except for keeping this secret from outsiders, Lu Chen himself had long been wary of this seed.

Thinking about it, it goes without saying that it was the puddle of fairy water in this tree hole that saved him from the desperate situation of black fire, without this, he would not even be alive now;

In such a place, Lu Chen regarded it as his last safe place from the bottom of his heart, and it can be said that he was convinced of it until today.

However, the door that suddenly appeared and opened in front of his eyes today clearly told him that there were still many secrets in this mysterious place, this seed of strange origin, that he did not know.

So this place, the secret that only he knows in this world, is still not an absolutely safe place?

Lu Chen's face looked a little gloomy, his eyes swept over the closed door, and he was speechless.

It was very quiet in the hollow of the tree, and after a while, Ah Tu seemed to return to normal, and climbed up from the ground over there. I don't know if this black dog also experienced a nightmare just now, but it seems that it seems to have a strong resistance to that kind of dream, except for a little discomfort that was initially revealed, it quickly shook its body and flicked its tail, and it seemed to be fine.

Lu Chen glanced at Ah Tu, his heart was slightly fixed, and after hesitating for a moment, he still stayed away from the mysterious door, walked to the center of the tree hole and sat down.

The territory here is twice as large as before, but the puddle in the center of the tree hole hasn't changed much, and it looks like it's smaller than before. However, in the waterhole at this moment, the water that was originally clear and colorless has been completely transformed, and it has become the immortal water full of abundant vitality when Lu Chen first entered here.

It was a strange and familiar feeling.

Lu Chen sat on the edge of the waterhole, saw the turquoise and vibrant water waves, reflecting his appearance, he couldn't help but smile, the memories of the year churned up from his mind, remembering many times when he was burned by the black fire, he rushed into the water and fell into the water, and for a moment, he even had the urge to jump into this puddle of water.

It's just that at this moment, when the corner of his eye swept over a corner of the pool below, he was suddenly stunned, and his gaze was also fixed.

In the depths of the water waves, there was a slight swaying and turbulence, and in some ripples, a black shadow swept by, swaying slightly.

It was a sensation that made his heart feel familiar, and almost at the same time as he looked at it, a dark flame burned in the depths of his eyes.

Lu Chen pondered for a moment, leaned forward, stared down at the water waves, and when his gaze passed through the vibrant green fairy water, and swept over the crystal clear water bubbles and dewdrops that floated from time to time, he saw that at the bottom of the waterhole, I don't know when it was already full of a strange plant, with slender green leaves, and that mysterious and peculiar black fire, as if accompanied by this plant spirit grass, appeared on these leaves from time to time.

The black fire burned on the green leaves, but it did not burn or damage the slightest bit of this plant, to be precise, the black fire was simply emanating from the inside of this spirit grass plant, sometimes bright and sometimes dark, swallowing and spitting.

Lu Chen looked at this strange scene, and almost immediately thought of himself, the same black fire was in his body, it seemed that it could also coexist with him in his body, never harming his physical body, but it could cause fatal and terrible damage to other people.

What is the reasoning behind this?

Lu Chen still hasn't figured it out, but after thinking about it carefully, he quickly remembered that the spirit grass under this waterhole did not appear out of thin air, in fact, it was he himself who brought these spirit grasses here. When he was still on Kunlun Mountain, Ah Tu played the role of a thief who stole chickens and dogs everywhere and dug spiritual grass for a while, and stole a lot of precious medicinal herbs from the Kunlun Sect's Hundred Herb Garden.

For this kind of behavior of not having a sense of public morality and taking advantage of the chaos to enrich his own pockets, Lu Chen severely criticized Ah Tu, taught him that he must not do this kind of stealing in the future, and then received all the valuable spiritual grass that Ah Tu stole into the tree hole.

Among them, there is a kind of spiritual grass called "black mud lotus", which can only grow in the mud in the water, even after picking, if it is not immediately refined into medicine, then it must be kept in the water, otherwise it will be dissipated for a while and become useless.

At that time, Lu Chen casually threw those black mud lotus into this useless pool, and afterwards the wind and clouds on Kunlun Mountain surged, and he encountered many storms and sinister waves in a row, and he had already forgotten this experience unconsciously.

But now in this puddle of water, the spirit grass that seems to be one with the strange black fire should be the black mud lotus that he threw into the water at the beginning.

Lu Chen never knew that there were still spirit grass plants in this world that could be combined with something strange like black fire, but if he thought about it carefully, before him, there seemed to be no third person who could have this kind of power except for the fire shaman back then and himself.

Uh, maybe another ...... Lu Chen turned his head and glanced to his side.

The black dog Ah Tu walked past him, and also came to the waterhole with a bit of curiosity, looking underwater.

The green water reflected Atu's face, which looked a little puzzled, and then the black dog once again showed a do-it-all personality that was ten times stronger than that of its owner, well, in short, reckless......

Ah Tu saw the black fire on the leaves in the water, it was no stranger to it, and then it was taken aback, its eyes widened, and then it roared angrily, and then its body jumped violently, and it jumped directly into the water with a "bang".

"Boom!"

The water splashed everywhere, splashing Lu Chen's shoes and trouser legs, Lu Chen was also a little dumbfounded for a while, and after reacting, he couldn't help but scold: "Stupid dog, you ......"

At that moment, Lu Chen really had the urge to cover his forehead and look up to the sky and sigh, shook his head and leaned into the water, grabbed the tail of this strange stupid dog, dragged it outward, and said: "You give me honesty, why don't we ...... down here?"

Suddenly, his voice fell, his brow furrowed, he stared at Ah Tu, who had just been dragged up by him, and saw that it had a leaf burning black fire in its mouth, and then Ah Tu was holding it in its mouth, chewing it, looking very sweet and delicious.

At the same time, Lu Chen clearly saw that the color of the dark flame in Ah Tu's eyes suddenly became several times stronger in an instant.
