The cold winter has passed, and the spring is gone, and it is the middle of summer.

The back mountain of Xiaohan Mountain.

After many years of channeling the qi of the earth's leylines, the mountain behind Xiaohan Mountain at this time is no longer the place where the miasma once spread.

Here the birds are singing and the flowers are fragrant, the water is full of stones, and it is a vibrant environment.

Somewhere in the back mountain, there is a hundred-zhang waterfall rushing down, roaring, smashing thousands of splashes.

Not far away, a mountain rock protrudes outward, forming a platform, on which a figure sits on it, unshakable like a sculpture.

The figure was dressed in an inconspicuous gray robe, his long hair was scattered, and he was flying wantonly in the wind, and although he sat cross-legged, he was still not much shorter than ordinary people, and it was conceivable that he was tall.

Compared with this waterfall and mountain rock, this figure is inconspicuous, but if someone is watching, the first thing to see must be this person!

On that figure, there seemed to be an indescribable charm that allowed him to transcend the limitations of his physical body, as if there was a huge aura that suppressed everything in these four directions.

This person is Sun Heng!

After a few months, the matter of the Yumen Mountain Demon Pill has long come to an end, and he has returned to Xiaohan Mountain again.

These days, he ignored the disturbances of the outside world and completely immersed himself in his cultivation.

On that day, he was infused with the energy of the Heavenly Sword, and he was lucky not to die, but was blessed by misfortune, saving an unknown number of years of accumulation.

Although that huge energy was left in him in the end, it still helped him get through all the tricks, and his strength increased several times!

And some of the skills that should have been accumulated for a long time have also been piled up under the unscrupulous squandering of energy.

It's like the true fire of Taiyin!

"Hoo ......"

As soon as the thought moved, a layer of blue flames suddenly appeared around Sun Heng's body.

This flame is ethereal and has no substance, and it is even more cold and piercing when viewed from a distance.

The burning flames did not hurt the mountains and rocks, nor did they have the slightest heat, but they were the only magical powers recorded in the Taiyin Secret Record.

This is also the second divine power that he can cultivate since the True Martial Seven Tribulations Sword Qi!

This supernatural power is not harmful to the physical body, but it has a miraculous effect on the soul of others, and it is the nemesis of ghosts and ghosts.

For Sun Heng, this magical power is a spell that can be cast on the Taiyin Secret Record.

Taiyin refining treasure trick!

He had been looking forward to this spell for a long time.

"Peng!"

There was a muffled sound, and a black coffin suddenly appeared in the ground below.

The black coffin has a mediocre appearance, but the yin energy stored in it is extremely amazing, and it has a miraculous effect, which can automatically refine zombies.

This is that it is suspended in the void under Sun Heng's manipulation, and it seems to be expecting something.

"Hoo ......"

At this time, with a wave of Sun Heng's hand, the Taiyin True Fire had already left his body, winding around the black coffin like a spiritual snake.

The faint blue flames spread to every corner of the black coffin, obviously not burning anything, but the flames suddenly flourished, piercing the flame seedlings several feet high.

"Crackling ......"

A subtle popping sound sounded from inside the black coffin, and as the flames burned, the black coffin in front of him seemed to begin to undergo a different kind of change.

The black is getting more and more transparent and pure!

The original black coffin was like a wooden board plastered with a layer of lacquer, but it changed in the direction of black jade.

The dark and deep color seemed to swallow up the sunlight, making the light around the black coffin dim.

At the moment of the scorching sun, within 100 meters of the surrounding area, it was dark and lightless, and the cold overflowed.

Sun Heng's eyes flickered, and he was not moved, but immersed in a wonderful feeling in his heart.

With the burning of the Taiyin True Fire and the progress of the Taiyin Refining Treasure, a strange connection with the black coffin quietly surfaced in my heart.

Different from the blood refining weapon, although this feeling is not very obvious, it is more close, as if there is an extra part of the body, and everything in the black coffin gradually becomes perceived.

Time passed, the sun rose and the moon set, and seven days had passed in a blink of an eye.

And after seven days of burning, this mysterious black coffin was finally refined by the Taiyin Refining Treasure.

"Huh!"

The black shadow in the void flowed, and the huge black coffin was as agile as a swimming fish, shuttling with Sun Heng's thoughts, like an arm.

"Click......

The light and shadow of the black coffin collided with a big tree, slashed away horizontally like a sharp object, and flew back with a slight obstruction.

And the big tree staggered and fell down with a bang.

"It's not very powerful. ”

Sun Heng muttered to himself.

This kind of strength is amazing for ordinary people, but for him, it is a bit too weak to knock down a big tree.

The thought turned, Sun Heng flicked his fingers, and a sword qi mixed with a little thunder power was already slashing towards the black coffin.

"Peng!"

With a muffled sound, an imperceptible crack appeared on the surface of the black coffin, and then quietly recovered under the nourishment of the internal yin qi.

Sun Heng raised his eyebrows, couldn't help but nod his head, and said, "This defensive power is amazing!"

Then with a wave of his hand, the black coffin suddenly became smaller, and in the blink of an eye, it had turned into a small coffin the size of a palm, like a toy.

The small coffin fell into his palm, and he held it in his hand and played with it at will.

At this time, the black coffin was dark and transparent, square, like a black brick, which made Sun Heng have the urge to pick up and dance.

"Heh......"

Led to a smile by the thoughts in his mind, Sun Heng shook his head lightly, and tried the other abilities of this black coffin a few times again, and then the streamer flashed, and the black coffin had disappeared into his dantian qi sea.

After the preliminary refining of the Taiyin Refining Treasure Formula, this black coffin finally has some characteristics of a magic weapon, and it can be changed in size as desired, and the imperial envoy is unhindered.

The speed of absorbing yin qi has increased tenfold, and the ability to refine zombies has also increased.

Of course, there's another trick.

That is, when he encounters a powerful opponent, he can hide in this coffin, hide all his breath, and no longer have to worry about being refined into a zombie by this black coffin.

Even if someone finds out, you can rely on the strong defense of the black coffin to resist!

There is one more way to save your life.

The black coffin sinks in the sea of dantian qi, and through the nourishment of true qi, the connection with itself will become closer and closer, and the imperial envoy will be more freewheeling.

This is the method of cultivators, but now Sun Heng can also show it on this black coffin!

After putting away the black coffin, Sun Heng let out a long breath, flipped his hand, and a seemingly ordinary long knife appeared in his palm.

Heavenly Sword!

Looking at the heavenly sword in his hand, Sun Heng's eyes flickered.

In the record of Jiang Li's essay, his mysterious master also said that this heavenly sword has another mystery.

But in addition to being indestructible, Jiang Li did not discover any secrets of this Heavenly Sword since his death.

Until Sun Heng killed a demon fox and cut a demon pill!

This heavenly knife can rob the body essence of the monster and make up for the person holding the knife!

Sun Heng used this heavenly sword to kill the master of the devil, and even the demon servant, but there was no reaction at all.

In other words, it only works on real monsters!

Two hundred years after Jiang Li's death, there was a great cool, and there was a demon in this world, I am afraid that except for himself, no one has ever killed a real demon with a heavenly sword.

No wonder this secret has never been discovered.

Sun Heng's mind turned, and as soon as he stretched out his big hand, the Taiyin True Fire burned again, and the Taiyin Refining Secret was cast.

In any case, this heavenly sword has a mysterious origin, and it is even more useful for restraining monsters.

"Zheng ......"

The real fire burned, the Taiyin Refining Treasure Recipe turned, and the Heavenly Sword in his hand jumped, and it turned into a streamer of light and disappeared into Sun Heng's sea of knowledge.

In the blink of an eye, the refining was completed!

"How so?"

Sun Heng was stunned for a moment, and then his eyebrows lit up, and the heavenly sword appeared in front of him again, one person and one knife were closely connected, his mind turned, and the heavenly knife traveled in all directions, which was a little more agile than the black coffin of the imperial envoy.

But......

How can it be so easy to refine?

This thing is even more mysterious than the origin of the black coffin, and it was refined in the blink of an eye!

And the magic weapon sinks in the dantian, this is common sense, how can this heavenly knife run into the sea of knowledge?

The dantian has a shape and a substance, located below the abdomen, but the sea is not, although it is located in the main body of the eyebrows, it is an illusory place.

After pondering for a long time, but there was no solution, Sun Heng had to shake his head helplessly, put away the heavenly knife, and with a wave of his hand, several storage bags appeared in front of him again.

These things can finally be refined and opened......
