In order to continue the next stage of cultivation, Lin Yu planned to unlock the outer seal of the source of spiritual light, allowing it to release more spiritual power.

The source of spiritual light was originally an innate spiritual treasure, but because the power was too strong, a large number of seals were set up internally by the ancient monks, and most of the power was completely sealed.

Lin Yu had tried to lift the ban on the source of spiritual light, but because his cultivation was too low, he had only unlocked three seals at most, and it couldn't last.

Now that Lin Yu has greatly improved his cultivation after entering the Foundation Building Realm, it is naturally not the same.

Lin Yu held up the source of spiritual light with one hand, and inside the brilliant and glittering gem, a trace of light could be seen swirling and wandering, densely packed with hundreds of ways.

These are the prohibitions set by the ancient monks, and each prohibition restricts a part of the power of the source of spiritual light.

Lin Yu concentrated on it, pinched the formula with one hand, and recited silently in his mouth: "Danshen, Zhenglun, Huben, Danyuan!"

As the voice sounded, Lin Yu drew four spiritual patterns in the void with one hand, and one after another light flashed from his fingertips, and then disappeared in a flash, merging into the source of spiritual light.

Buzz –

There was a humming sound in the void, and then the light of the source of spiritual light was so full that it illuminated the entire underground dojo so brightly that it was impossible to look at it directly!

Hiss –

A hissing sound sounded, and a large amount of spiritual energy poured out from the source of spiritual light, permeating the entire underground dojo!

Lin Yu took a deep breath and felt extremely comfortable!

Now the concentration of spiritual energy around is already comparable to the cultivation environment of the cultivation realm, if this concentration of spiritual power can be maintained all the time, the next cultivation should not be a problem!

But Lin Yu's current strength is more than that!

Breaking the four seals is no problem for him, and he can continue!

Lin Yu pinched the trick with one hand, and continued to whisper in his mouth: "Yuan Heng, Li Zhen, delusional!"

Three points of light emerged from his fingertips, and then injected into the source of spiritual light again, and the seal of the source of spiritual light was unlocked three more times!

Woo——!

A strange wind suddenly surged in the underground space, and several black cracks appeared in the surrounding space, and the interior was dark and dark, which was terrifying to look at.

Lin Yu was slightly surprised: "The spatial divine power of the source of spiritual light has been stimulated!"

The source of spiritual light is a magic weapon with its own spatial supernatural powers, but this power will not appear in the sealed state.

Lin Xiaomeng had caused the source of spiritual light to run away before, and at that time, he had caused the space of the entire building to be disordered.

Unexpectedly, Lin Yu unlocked the seven seals in one breath in a row today, and even made the spatial divine power of the source of spiritual light begin to appear!

The pitch-black cracks in the void continued to rotate, gradually merging into one place, forming a huge gap more than two meters long.

The yin wind blows out from the cracks, making people's hairs stand on end.

Whew————!

A low roar came from the gap, and then with a bang, a huge pitch-black claw grabbed the edge of the gap and began to tear hard!

Lin Yu was taken aback again, the spatial crack was normal, but where did the alien beast in this crack come from?

The claw that stretched out from the crack was more than a meter long, the front end was divided into three toes, and the sharp claw hook flashed a little cold light, and slashed across the dojo floor with a piercing sound, leaving deep scratches!

Lin Yu raised his eyebrows: "This is ...... Returning Beast?"

If this monster really broke open the crack and rushed over, even if Lin Yu was not afraid, the villa at the foot of the South Mountain would be razed to the ground!

Lin Yu didn't dare to hesitate at all, and slashed out of thin air with one hand and one hand, "Delusion, Lizhen, Yuanheng!

Three rays of light entered the source of spiritual light, and the surrounding space vibration suddenly stopped, and the crack that was more than two meters long also slowly closed, and the giant beast behind the crack let out an unwilling roar, and finally had to reluctantly withdraw the giant claw.

Everything around him returned to calm, and Lin Yu looked at the source of spiritual light in his hand, his brows furrowed slightly.

The Guiyuan Beast is a common spirit animal in the fairy world, with a lion-like appearance, and is often used by the fairy gate as a gatekeeper spirit animal.

Unexpectedly, when the ancient monk sealed this source of spiritual light, he actually used the spatial magic power of this treasure to seal a Guiyuan beast in it!

This should also be the mechanism left by the ancient monk in the source of spiritual light, if the seventh layer of sealing is unlocked, this Guiyuan beast will inevitably be released, and a fierce battle will inevitably be inevitable at that time.

It seems that this seventh seal is a stage, and the ancient monk left this Returning Beast is also a test for those who break the seal.

Only by defeating the Returning Beast does it mean that you have enough power to control the source of aura.

The Source of Spiritual Light is a powerful treasure that can cause unimaginable disasters if it falls into the hands of an incompetent person and causes it to get out of control.

The Returning Beast is only the first test, and as the subsequent seals continue to be unlocked, there should be other tests in the second and third stages.

Of course, for Lin Yu, the first thing he had to face at present was this spirit beast that guarded the seventh seal.

Judging from the size of the claws, this Guiyuan beast should be seven or eight meters long, and with Lin Yu's current cultivation, it can barely cope with it.

However, the Guiyuan Beast's body is as hard as steel, and it is difficult for knives and guns to enter, and Lin Yu does not have a magic weapon in his hand now, so I am afraid that it will be a headache to fight.

After Lin Yu pondered for a long time, he muttered to himself: "It seems that I can only unlock the first four layers of seals at present, and after I successfully refine the jade dragon horn, I will release this Guiyuan beast and kill it to break the seal." ”

Lin Yu put away the source of spiritual light, and then took out the pure white jade dragon horn from his backpack.

This jade dragon horn is more than a foot long, the whole body is pure white and flawless, and the fingers gently caress on it, and the sound of the dragon's groan can be faintly heard.

It is indeed a superb spiritual material.

Lin Yu took this jade dragon horn and looked at it for a long time, and according to the shape and texture, he finally decided to refine it into a short sword.

After the vajra exploded, Lin Yu really needed a magic weapon that was easy to carry and had strong attack power, so the dragon horn short sword was very suitable.

The refining of magic weapons needs to be engraved in the spirit pattern, and the primary spirit pattern is divided into five systems: gold, wood, water, fire, and earth, with fire corresponding to attack, earth corresponding to defense, water corresponding to control, wood corresponding to recovery, and gold corresponding to strengthening.

The vajra and talisman ring that Lin Yu had refined before were all engraved with only one spirit pattern, with the only exception being the peachwood sword, which was engraved with two spirit patterns of gold and water.

Now that the foundation has been built, Lin Yu's control of the spirit pattern has far exceeded before.

So on this jade dragon horn, he plans to engrave five spirit patterns!

Gold, wood, water, fire, and earth, all five elements are complete!

This jade dragon horn itself is a piece of extremely high-quality spiritual material, and under the blessing of the five spiritual patterns, the power must be extremely powerful, and it can fuse the power of the five elements elementally, which is enough to be called a top-grade magic weapon.

However, the refining of high-grade magic weapons is naturally much more labor-intensive than before, especially the power balance between the five spirit patterns, once something goes wrong, all the previous efforts will be wasted.

With Lin Yu's current cultivation, it would take at least ten days or so to complete the refining of this jade dragon horn.

Lin Yu calculated the date in his heart, and then shook his head: "The date of the battle with Feng Qianshan is approaching, and it seems that there is no way to wait for the refining to be completed before setting off." ”

"I'll ask Teacher Zhang for leave tomorrow, and then I'll let Fang Wu arrange it and set off for the north. ”
