Shi Xuan didn't go all out before, just because he was afraid of stimulating big fluctuations and attracting those heavenly demons, but if it dragged on any longer, the heavenly demons might also come, so Shi Xuan immediately made a decision, and the Heavenly Thunder Demon Sword was unfurled, and a thick heavenly thunder was split in the air, which hit the tree demon directly, and then one after another, after the nine heavenly thunders, the towering trees that were dozens of zhang high and hugged by dozens of people were wiped out, and the remaining roots of the tree also became char.

After the blow, Shi Xuan withdrew the Yin and Yang two cylinders and landed on the remains of the tree demon's body, and the Heavenly Thunder Demon Sword circled beside him.

Originally, Shi Xuan wanted to see if he could find the root of the 10,000-year-old tree demon, so that when Chu Wan'er learned the five Taoist techniques in the future, he would be able to find one less material, but those roots were all split into charcoal, and they were really unusable, but there was a faint fragrance in the smell of coke, and the fragrance was deep into the bones, which made people clear, and following the breath, Shi Xuan found a small hole in the half-cut black charcoal-like root, and then took out three yellow tree fruits from it, but unlike the one given to Shi Xuan, there were no golden spots on it.

Is this really the 10,000-year-old tree demon fruit? That is, the tree fruit that can benefit the longevity of a Jiazi? The 10,000-year-old tree demon fruit is the product of the tree demon's 10,000-year-old flowering and 10,000-year fruit, which can not only prolong life, but also for itself, it is also a powerful help to condense the demon pill.

Shi Xuan wasn't sure, so he was going to put away the three tree fruits, and wait until he returned to the door to ask a real person to identify them before taking them, but the monkey suddenly rushed in front of Shi Xuan, looking at the tree fruit in Shi Xuan's hand, and the fluffy paws saluted.

"You want to eat?" Shi Xuan asked.

The monkey kept nodding his head, and he looked very well-behaved.

In line with the idea of abducting the monkey, Shi Xuan thought for a while and said, "If you eat it, you have to follow me, okay?" If the monkey is really the Heavenly Spirit Treasure Yuan Spirit, then what kind of slave prohibition and the like will not work, but will destroy its own impression. Tongtian Lingbao can only leave a little imprint in the spirit forbidden core if Yuan Ling is willing.

The monkey continued to nod his head, eager to eat the fruit immediately.

Shi Xuan took out a tree fruit and handed it to the monkey, the monkey's head was divided by five by two, and then swallowed the tree fruit into his stomach, and a burst of blue light seemed to flash on his body.

"Alright, follow me. Shi Xuan said with a smile.

The monkey pulled his eyelids in one hand, spat out his tongue, grimaced, and then disappeared into the trees with a puff of smoke.

Shi Xuan really wanted to shout at this time: "I'll spit it out if I eat mine!" But it's just thinking about it, how can it be so easy to be abducted, and slowly deepening the favor is the right way.

After returning to the small lake, Shi Xuan found a hidden place, restrained his breath, and hid his body, because of the battle just now, he didn't know if it would attract the Heavenly Demon, but he hadn't come for so long, so he shouldn't come.

............

A few days later, Shi Xuan searched all around, but still did not find any possible traces of the old man of the sword, but he encountered several waves of heavenly demons and was avoided by Shi Xuan.

At this time, Shi Xuan sat cross-legged on the edge of the small lake on the opposite side of the cliff, looking at the sword mark on the stone wall, if the dryad didn't lie, the old man of the sword slashed a sword here for no reason, why did this happen?

In the past few days, Shi Xuan has also felt this sword mark again, he has not found any news left by the old man of the sword, and there is nothing unusual, and even Shi Xuan has used Dao techniques to attack this stone wall, except for proving that the stone wall is hard, but there is only one more hole, there is no use.

At this time, without any clue, Shi Xuan thought to himself, since the old man sword slashed a sword for no reason, it would be better to try it himself, simulate the situation of the old man sword at the beginning, in the words of the previous life, this is called the reorganization of the case.

Thinking of doing it, Shi Xuan pointed out with his hand, and the Heavenly Thunder Demon Sword turned into cyan sword light, slashing towards the stone wall in the direction of that sword mark.

As soon as the sword light slashed on the stone wall, Shi Xuan felt that the Heavenly Thunder Demon Sword was light, fluttering upward, unable to exert force, this swift sword actually did not leave any traces on the stone wall.

Although he couldn't leave a trace, Shi Xuan still showed a smile on his face, there was really something strange here, most of the old sword men knew about the situation here in the ruins of other peaks or from the information left by the surviving disciples of the Heavenly Sword Sect, so he rushed here in a hurry, but why did he never appear again, was it very dangerous inside?

Shi Xuan didn't have time to think about this now, the primary problem at this time was how to leave sword marks on this stone wall, and he didn't know what kind of formation prohibition the Heavenly Sword Sect left behind back then, which not only made others unable to detect it, but also made the flying sword out of control, and it couldn't exert its power after slashing the stone wall. ,

The cyan sword light hovered around Shi Xuan's head, and then slashed towards the stone wall at an incredible speed, Shi Xuan was now using all his sword qi thunder sound, hoping to break through the prohibition of that formation.

The sword light is very fast, it has already touched the stone wall, but the faster the sword light, the greater the rebound power, and when it falls on the stone wall, the cyan sword light is already the end of the strong crossbow, and it is completely unable to leave sword marks.

After trying a few swords in a row, it still didn't work, Shi Xuan's face was solemn, and he once again exerted his sword qi thunder sound, and at the same time, the Taiji diagram turned into a golden bridge on the other side, and with an all-encompassing, sacred and mighty momentum, it fell on the stone wall.

The breeze had stopped, the falling leaves had stopped, and only the cyan sword light was slashing through the stone wall.

Silently, Shi Xuan only felt the huge rebound power from the Heavenly Thunder Demon Sword, and when everything was over, there was still no trace on the stone wall. Shi Xuan couldn't help but sigh in his heart, it was worthy of the formation left by the ancient super sect, and he didn't know which old-timer laid it out.

After pondering for a while, Shi Xuan took a breath and divided the cyan sword light into two, the void sword light slashed towards the stone wall, and the clouds were light and light along the way, without the slightest abnormality.

Just when the void cyan sword light was about to touch the stone wall, Shi Xuan's mind moved, and it turned from virtual to real, but as soon as it turned into a physical sword light, the huge rebound force appeared, not giving Shi Xuan a chance to cut the cliff wall at all.

After that, Shi Xuan used the Void and Reality Sword Light Differentiation and the Taiji Diagram together, but he still couldn't break through the formation prohibition on the stone wall.

Shi Xuan stopped the sword light and looked at the sword marks on the stone wall, the old man of the sword had practiced sword qi, which was equivalent to a first-order Dao technique, plus the sword qi thunder sound and the natal flying sword, it almost had the power of a second-order Dao technique, could it be that he really had to reach this level to break through the formation prohibition, and other tricks would not work?

If his Wai Dan is still there, using the method given by the Guanghan Sect, ignoring the difference in attributes, he can use the second-order Star Demon Slaying Sword Qi, and even if he doesn't use the secret method, he can use the Heavenly Thunder Demon Sword with all his strength through the Wai Dan, plus the sword qi thunder sound, it also has the power close to the third-order Dao technique, but now that the Wai Dan has exploded, Shi Xuan was a little helpless for a while.

Just looked at the stone wall, and after a long time, Shi Xuan's eyes suddenly lit up.
