With a sigh, I walked to the depths of the cave with Mr. Yi and Nie Yiyuan, here I am here for the second time, and Mr. Yi has already explored three or four times.

There used to be a blazing wind blowing in the cave, and I had to use my own cultivation to resist in order to move forward, I couldn't go far, and Mr. Yi walked closer than me.

However, this time the cave is very cool, it is very hot all year round, and there is no dampness in the cave, but it is convenient to walk.

I can see at night by channeling my true qi to the meridians of my eyes, and Mr. Yi and Nie Yiyuan both have their own methods of night vision, so we didn't ignite the fire, so as not to alarm the things in front of us.

The more you go forward, the larger the space in the cave, Mr. Yi pointed to the cave wall in front of him, and Nie Yiyuan and I hurriedly looked over.

There was not a grain of sand on the walls of the cave here, but a layer of hard, shiny, ceramic-like things, which I knew was physically called vitrification, and only after being exposed to the heat of a furnace.

"How hot this tunnel must have been......"

Nie Yiyuan had never been to this cave, so he couldn't help but sigh.

I touched the vitrified cave wall, I don't know if it was my psychological effect, I felt that the cave wall was still warm until now, what is the end of this cave, it can't be a crater.

"It's all here, since it's not hot anymore, let's keep going, the Immortal Tree and the two Yin Beasts should be inside."

Mr. Yi nodded, glanced at Nie Yiyuan, and said:

"And the roots of the immortal tree stretch, and it knows the movements of a hundred miles, so you can just ask the immortal tree about the whereabouts of your son."

Knowing that the Immortal Tree also had the function of monitoring and searching for people, Nie Yiyuan immediately became energetic, and walked forward, and we hurriedly followed behind.

After walking another five or six miles, I obviously felt that the tunnel was cold, and goosebumps got on my arms, and Mr. Yi and Nie Yiyuan felt more keenly than me.

"How did it get cold?"

"The cool air is coming from the front, what is it here, why is it spitting heat waves and spraying cold air."

After discussing for a while, there was no result, we could only continue to walk forward, and walked another three or four miles, the temperature was already so cold that Nie Yiyuan, a true master realm refining powerhouse, felt a little uncomfortable, and we finally walked out of the tunnel!

As soon as we walked out of the tunnel, we were enveloped in a burst of emerald green light, our eyes had no brilliance except green, our noses were full of a faint resinous aroma, and the freshness of the branches and leaves of the trees, this smell was very similar to that on the branches of the immortal tree, only a little stronger.

Bathed in the green light, the tense muscles relaxed, the exhaustion of the body was swept away, and the original dark wounds on the body were quickly healed by the green light, this process was extremely sour, I couldn't help but cry out.

Mr. Yi and Nie Yiyuan were similar, and I also heard their ecstatic cries, and it took a long time for the green light to dissipate.

I opened my eyes slowly, and was fascinated by the sight—

In front of him was a towering tree that could not be kept by ten people, firmly rooted in the ground, with a blue and white bark without even a wrinkle, and a thin layer of resin wrapped on the surface.

Above the main trunk, there are countless branches, and countless leaves, about seventy percent of which are green and thirty percent golden.

There is no doubt that this should be the Immortal Tree itself.

Mr. Yi glanced up at the immortal tree, his eyes couldn't help but light up, and he sighed:

"This is the Immortal Tree, its roots are deep in the earth, every leaf has infinite life, and it has already given birth to its own spiritual wisdom.

If it weren't for the fact that it only grows vitality and is not good at fighting, what Nine Yin Beast, what Jiaolong and Phoenix, it is the most powerful monster in the world throughout the ages, and its life level is naturally high!

It's a true immortal in the sky, I'm afraid it's nothing more than that......"

Seeing the Immortal Tree, I felt that myself, the Nine Yin Beasts, were incomparably small, this was the most powerful creature in the world! If you can use the power of the Immortal Tree, it will be easier to collect the Nine Yin Beasts, deal with the Black Robe Society, or deal with the birth of the Jiaolong two years later.

I approached the Immortal Tree, and in a similar way to communicating with the branches of the Immortal Tree, I released a wisp of Divine Thought, wanting to have a direct conversation with the Immortal Tree, but the Divine Mind only came into contact with a huge vitality, and the Immortal Tree's spiritual wisdom did not communicate with me.

I tried to wake it up, but the Immortal Tree still didn't answer, as if it were just a normal tree.

I frowned and said:

"I tried to communicate with it, but the Immortal Tree didn't respond to me, is it because the Immortal Tree doesn't want to talk to us, or is the Immortal Tree under control?"

After saying that, I shook my head, with the powerful vitality of the Immortal Tree, even if the Nine Yin Beasts gathered, don't want to hurt it even a little, and it is even more unrealistic to control it.

Nie Yiyuan walked over and touched the immortal tree, it may be that the immortal tree vitality was poured into his body, Nie Yiyuan couldn't help but shudder, and then shook his head:

"It's impossible to be controlled, I don't feel malice, but why doesn't the Immortal Tree ignore us......"

Nie Yiyuan and I were puzzled, at this time, Mr. Yi stepped forward and took out a knife to try to scrape off a little resin from the immortal tree, but the resin on the surface of the immortal tree was as clear as jade and as hard as steel, and the knife was bent without scraping a single star.

Mr. Yi could only give up, sighed and said:

"The larger the body, the more powerful the monster is, the more difficult it is to give birth to intelligence, speak, and shape.

The body of the immortal tree is more than a thousand feet high, and the roots are even deeper into the earth, if it is considered a monster, it is the largest monster in the entire human body, and it is not easy to be able to give birth to spiritual intelligence, don't expect to transform and speak, and it is very difficult to even use divine consciousness to transmit sound.

Therefore, the immortal tree should not communicate with us, but it should not be unwilling, but impossible, let's find those two yin beasts on our own. ”

Listening to Mr. Yi's words, I couldn't help but be stunned.

It's the first time I've heard about the knowledge that the monster body is bigger and stronger, the more difficult it is to generate spiritual intelligence and transformation knowledge, and our Han family has studied a lot of monsters, but I haven't seen a similar theory in either my grandfather's teaching or any classic codex.

Among the various sects of the Daomen, there should be no similar classic records, but recall that the demons I have encountered, most of them can give birth to spiritual wisdom and speak, most of them are the demon fairies of the old Northeast Ma family, and the blind old fox Hu Baqian, they are relatively small, even if they are not very Taoist, they can speak.

And like the big black fish in the Pig Hair River, although it has practiced for many years and has a very high Taoism, it can't speak directly, and can only use its divine sense to transmit sound in its heart, which is not very stable.

The Nine Yin Beast was better than the big black fish, and the transmission of divine consciousness was relatively stable, but it couldn't speak.

The Nine Yin Beast can transform, among which the 'lazy' body is a big orange cat, but it can transform into a big leopard, maybe the leopard is the body! As for the usual appearance of an orange cat, his strength has also been reduced a lot, perhaps in order to obtain a higher spiritual intelligence......

I glanced at Mr. Yi with some surprise, this guy's research on monsters has gone farther than our Han family.
