Xuanyuan Hong looked from afar, and saw that in the territory of the old demon of Black Mountain, he saw a ball wrapped in huge branches and vines rolling slowly, through the gap of this ball, a red eggshell could occasionally be seen, and Sun Hao had been completely submerged by the branches and vines.

In the encirclement, Sun Hao's Fire Aegis is opened, the effect is wonderful, the defense of the Fire Aegis is not very prominent, but there is a unique way of defending the center and attacking, when the branches and vines of the old demon of Montenegro attack or try to entangle Sun Hao, the fire shield on Sun Hao's body always splashes bursts of fire, burning the branches and vines that are approaching, and even the root python of the old demon of Montenegro, as long as it is close to Sun Hao's eggshell, it will always be scalded and screamed, and turned into a prototype.

The old demon of Montenegro doesn't know how many thousands of years it has existed, and the general flame is really helpless, but the fire shield supported by Sun Hao is a bit special, first, this is Sun Hao's natal little supernatural power, although there is no real magic power to double the attack and defense, but it has also been greatly strengthened, based on Sun Hao's powerful true qi accumulation, defense and flame splash damage are quite good, the old demon of Montenegro is not easy.

What's more, Sun Hao's foundation-building true fire was replaced by a small flame, and after the fire shield was cast, it brought some of the characteristics of the small flame, and Sun Hao's small flame had devoured the Yi Shenyan and the dark blue flame, and the flame strength was far beyond that of ordinary monks.

For various reasons, although the old demon of Montenegro surrounded Sun Hao and made Sun Hao unable to return along the way, he was never able to break Sun Hao's Fire Aegis, and many branches and vines and roots were injured by Sun Hao's Fire Aegis reflected flames, and the injuries were not light.

The old demon of Montenegro surrounded Sun Hao, and Sun Hao's assault speed couldn't come up, but the old demon of Montenegro couldn't help Sun Hao for a while. In the encirclement, there was a puff of green smoke from time to time, but this was caused by the branches and vines of the old demon of Montenegro being completely burned, and the branches and vines that were burned into fly ash could not be reborn again, and were really removed.

Although Sun Hao's assault speed was not fast, but the sword pierced non-stop, it was still moving forward, and finally, Sun Hao worked hard and kept assaulting for two hours, and reached the edge of the black mountain old demon giant tree, and the last sword stabbed directly, and with a hula, Sun Hao rushed out of the encirclement with a red eggshell.

Behind Sun Hao, the entire Black Mountain Old Demon Giant Tree was trembling, and its branches were dancing wildly, as if a giant was standing in place, roaring constantly.

How many years have the old demon of Montenegro suffered such a loss as today, not only did he not catch his prey, but also let this little ant burn how many branches and roots of his own branches? If it weren't for the inability to move, the old demon of Montenegro must have chased after him a long time ago.

Sun Hao dispersed the Fire Aegis, harnessed the Agarwood Sword, and returned to Xuanyuan Hong's side.

At this time, Sun Hao's breath was short, his face was slightly red, there were fine beads of sweat on his forehead, and his green shirt was slightly messy. Just now, the attack of the old demon of the Black Mountain was very dense and powerful, and the Fire Aegis almost couldn't support it.

After Sun Hao took a few breaths, Xuanyuan Hong asked with concern, "How is it?" Sun Hao!"

Sun Hao said with palpitations: "Amazing, this old demon of the Black Mountain doesn't know how long he has been cultivating, and the slightly thick branch attack is not weaker than the foundation building spirit beast I used to deal with, if you want to get rid of this guy, you may have to spend a lot of time."

Xuanyuan Hong nodded, and there was some solemnity on his face: "The old demon of Black Mountain is in this secret realm, there are no natural enemies, and the aura is sufficient, it is indeed quite difficult."

After this temptation, Sun Hao and Xuanyuan Hong figured out part of the strength of the old demon of Montenegro.

The attack methods of this black mountain old demon mainly include: all-round siege, branches turned into sharp sword stabs or whips, roots turned into giant python bites and other ways, combined with the previous temptation, if you break through the monk's defense, there should be a means of toxin attack. The strangest thing is that the root python sprang out of the ground to attack, and it stands to reason that the ground has been pierced with thousands of holes, but after these roots returned, Sun Hao and Xuanyuan Hong found that the ground within the scope of the old demon of Montenegro was covered with grass, and there was a little sign of destruction.

In addition to attacking, the most prominent ability of the old demon of Montenegro is also the ability to regenerate branches and roots, and the ability to heal themselves, Sun Hao found that some of the branches that had just been burned by himself had recovered after only a stick of incense, and they were all restored, and they were as new as new branches. This ability is also quite troublesome, that is to say, it is difficult for this black mountain demon to be hit hard.

In this temptation, Sun Hao still has gains, that is, he has discovered the real strength of the natal little supernatural power, and the real strength of the natal small supernatural power is precisely the less consumption that Sun Hao ignored before. In the face of such a high-density and high-intensity attack from the old demon of Montenegro, Sun Hao only relied on his initial cultivation in the foundation building, and the Fire Aegis supported it for two hours, which was unimaginable before.

The real strength of the natal little supernatural power may still be above the low consumption.

Of course, this temptation also made Sun Hao certain one thing, that is, this old demon of the Black Mountain has cultivated into a refinement, although he has not turned into a human, but he already has a high level of wisdom, not just that ordinary spirit beasts have spirituality.

Xuanyuan Hong and Sun Hao synthesized the results of the trial and discussed it, and they both felt that this old demon of the Black Mountain was very tricky, and they felt a little clueless.

In the end, Sun Hao remembered a record in the "Morning Glory Sutra": "Plants and trees become essences, when there is a wood heart, a thousand years of inches, the soul is hidden in it, and the wisdom is as ...... as ordinary people", according to the annotation of the "Morning Glory Sutra", the genus of plants and trees, after cultivation, will generate a wooden heart, and the wooden heart is deeply hidden in the ontology of plants and trees.

If the record of "Morning Glory" is true, then the old demon of Montenegro in front of him should have generated a wooden heart, perhaps, this wooden heart is the key point of the old demon.

It's just that Sun Hao looked at the overwhelming torso of the old demon of Montenegro who soared into the sky, and said in his heart that to find Mu Xin in this old demon is tantamount to looking for a needle in a haystack.

Seeing Sun Hao's thoughtful look, Xuanyuan Hong asked, "Sun Hao, do you have any way?"

Sun Hao nodded, shook his head again, and said: "The creation of the world has its own advantages and disadvantages, this old demon of Black Mountain, should have its key points, the classics record that it should have a wooden heart, and a bad wooden heart, in order to finally destroy its soul and destroy the tree demon, but, Xiaohong, you see, this old demon of Black Mountain is so huge, how can we find its wooden heart?"

Mu Xin?

Xuanyuan Hong praised Sun Hao: "Sun Hao, you are really good, you are really knowledgeable!" Over, a smile appeared on Xuanyuan Hong's face: "If this old tree really has a wooden heart, I have a way to know the general range of its wooden heart."
