A few days later.

In a valley with towering ancient trees, strange stones, and ancient vines, Lin Xiao quietly opened up a rather deep cave.

The entrance to the cave was tightly concealed, without a trace, and this place was a sparsely populated place, and if it were not for someone passing by and the breath leaking out, almost no one would have noticed.

Moreover, inside the entrance of the cave, Lin Xiao released the purple corpse puppet and guarded it to the death.

If it weren't for the powerful Martial Emperor powerhouse, even if someone or spirit beast stumbled upon him and dared to do something to him, it would be a dead end.

After doing this, Lin Xiao sat cross-legged on the ground in the cave mansion, and after breathing for a while, he activated the Eternal Heavenly Spirit Technique and began to fuse spiritual energy.

At this time, in Lin Xiao's mind, the rolling spiritual energy was already surging.

The vast thunder energy, and the devouring and incineration energy, began to fight together.

Although the two spiritual energies had been running in Lin Xiao's mind for a year, after all, they were the sources of heaven and earth energy with two different attributes, and there was a huge rejection in itself.

Lin Xiao's mind seemed to be churning in the ocean, and under the confrontation of the two energies, his entire mind began to turbulent, and the terrifying energy was ravaging his mind.

And under the operation of the mysterious Eternal Heavenly Spirit Technique, the repulsive power weakened a little more.

However, as the two spiritual energies planted in their minds began to move in opposite directions, the more terrifying thunder energy and the Azure Fire Spiritual Energy of Devouring Heaven were repelled against each other.

Lin Xiao's mind was hit by an even more powerful energy impact.

Lin Xiaodu faintly felt that even if he was running the Eternal Heavenly Spirit Technique, he was about to lose control, and his energy seemed to be out of balance and would explode at any time.

His consciousness also felt as if he was about to be burned.

However, Lin Xiao still endured the great pain and the consciousness that he might fall unconscious at any time, concentrated his energy, and survived.

Because he knew that once he was unconscious, or, the slightest carelessness, the two energies would explode.

Once it explodes, not only will his mind be blown into nothingness, but his entire body will be blown into ashes.

No psychic controller can withstand the explosion of two psionic abilities in his mind.

In the extremely difficult balance to adhere to, Lin Xiao's ability to control the Eternal Heavenly Spirit Technique was also constantly increasing, and Lin Xiao also moved the two spiritual energies slowly, constantly getting closer.

Eventually, they touched each other and began to merge.

The whole process, Lin Xiao took more than a month, Lin Xiao's body was also brushed by the overflowing energy residual heat, the body surface was black and white, blue and blue, the clothes had been steamed dry, and black smoke came out of his body.

In the end, the two psionic powers were completely fused together.

"Whew!"

At this time, Lin Xiao's mind had already deteriorated, and terrifying spiritual power emanated from his mind, spreading in all directions.

His spiritual power began to climb, breaking through the realm barrier of the fifth-grade high-grade spiritual power, and advancing to the sixth-grade primary spiritual power realm.

Then, he broke through the sixth-grade primary spiritual power realm and reached the sixth-grade intermediate spiritual power realm, and almost broke through the sixth-grade intermediate spiritual power and advanced to the sixth-grade high-level spiritual power.

In the end, it was still in the sixth-grade intermediate spiritual power realm and stopped.

It can be said that it has reached the peak of the sixth-grade intermediate spiritual power, and it is possible to break through again at any time.

At the same time, the powerful martial monarch aura also emanated from Lin Xiao's body, urging all the sweat and dirt on his body to disperse.

Lin Xiao's Yuan Force cultivation was also fused with the overflowing energy of the spiritual energy, and by the way, it improved the cultivation of a martial artist.

Moreover, he almost broke through the Sixfold Martial Monarch and advanced to the Sevenfold Martial Monarch, and was at the peak of the Sixfold Martial Monarch, and there was a possibility of breaking through again at any time.

Not only did the spiritual power break through, but Lin Xiao's physical body also became more and more powerful.

At this time, Lin Xiao already felt that both in the dantian and in the flesh were full of explosive power.

What is even more obvious is the spiritual power in his mind, which seems to have undergone earth-shaking changes, and the spiritual power has skyrocketed several times.

Lin Xiao already felt that his spiritual power had now exceeded the level of being able to fight across one level before, and it seemed that he could directly fight across two levels of spiritual power.

In other words, with his current sixth-grade intermediate spiritual power, it seems that he can directly fight against the seventh-grade junior spiritual controller, that is, the level of the Triple Martial Emperor.

And his Yuan Force, in the fivefold realm of the Martial Monarch, can kill the first Martial Emperor and resist the Triple Martial Emperor, and now that he has broken through the first one, he can be sure that he can kill the ordinary Dual Martial Emperor and resist the Triple Martial Emperor.

And the strength of his spiritual power seems to be about the same.

Therefore, Lin Xiao only guessed that his sixth-grade intermediate-level spiritual power might be able to fight across two levels, which was quite a terrifying improvement.

Of course, the specific combat power has to be tried to know.

If it is really as he guessed in his heart, the spiritual power and the yuan power have reached the level of resisting the Triple Martial Emperor, and the combined attack of the two means, Lin Xiao is confident that he can defeat the Triple Martial Emperor, and even, it is no problem to resist the Quadruple Martial Emperor.

In other words, his real combat power is very likely to have reached the level of Sheng Qianyu.

As for Sikong Sword and Dongfang Kaiyuan, Lin Xiao felt that he was not strong enough to that extent.

However, with such a huge increase in combat power, Lin Xiao was still excited in his heart.

Moreover, what also made him excited was that the Ancient Heavenly Spirit Recipe had been upgraded again, from the intermediate level of the Xuan Rank to the advanced level of the Earth Rank.

With the upgrade, another energy martial art was derived, the Holy Hand Covering the Sky.

The holy hand covers the sky, just like the hand of the martial saint, and the power of martial arts is farther terrifying than covering the sky with one hand!

In addition, the spiritual energy that requires the fusion of three spiritual energies is unexpected, and the power is even more unimaginable.

He had another strong hole card.

At this time, his temperament seems to have changed, his spiritual power has improved, and the whole person seems to be a little more energetic and light, and his ordinary, upright and clean face reveals a bit of handsomeness and lightness.

At the same time, it has a sense of maturity and grandeur.

This is the temperament that the strong invisibly reveal.

"I don't know what the situation is outside?" After the joy, when he came back to his senses, Lin Xiao was worried again.

He focused all his energy on fusing psionic energy, and he forgot the specific time, but he felt that it was a long time.

If it really takes too long, the Martial Emperor on the side of the emperor attacker recovers, and the two sides may go to war again.

On the positive side, the situation is not too clear.

Immediately, he took out a black robe and put it on, Lin Xiao rushed out of the cave, gave an order, waved his hand, and put the purple corpse puppet guarding the entrance of the cave into the storage ring.

Rushing out of the cave, Lin Xiao instantly rose to the sky and rushed into the sky.

At this time, under the bright sun, Lin Xiao suddenly had a dazzling feeling.

And in his sight, at least one or two thousand miles away, there were countless sword lights and sword shadows flickering in all directions, and there seemed to be a faint roaring sound coming over.

"Someone is fighting?" Lin Xiao showed a slight look of surprise, in such a remote place, there were still people fighting?

Moreover, the number of people who are still not fighting seems to be quite a lot.

The strength of the two sides should not be too weak, otherwise there would not be such a big movement.

"Go and see!" Immediately, Lin Xiao rushed towards the place where the battle was fighting.
