Hou An sneered for a while, stood up in shame, lowered his head, and didn't dare to look at Su Fang.

Just now he really thought that Su Fang was preparing to unload the mill and kill the donkey.

The cave has been found and successfully opened, why not the treasure inside?

It's normal to have this thought.

If it were someone else, Hou An would indeed have been killed.

But Su Fang doesn't have this hobby, it doesn't matter if he kills Hou An or not.

Instead, he was left behind, maybe it would be useful in the future.

Thinking of this, Su Fang didn't break it, and said indifferently, "Let's go, remember, follow me." ”

"Yes...... Yes, sir. ”

Hou An shuddered, nodded hurriedly, and followed behind Su Fang.

The two of them also only walked three steps, and holes the size of ping-pong balls appeared on the walls on the left and right sides, shooting iron spikes from inside.

"Woohoo!"

Bang Bang Bang!

Hou An's heart, as soon as it reached his throat, immediately sank, opened his mouth wide, his face was dull, and he was shocked and silent!

It was only because the two wall panels formed by the condensation of the earth in an instant suddenly rose from the ground to block the attack of the iron thorns.

In the middle of the wall panel, Su Fang and Hou An have no impact.

As I walked inside, the two wall panels also moved together, resisting the iron thorns that kept shooting from the walls on the left and right.

When I was about to walk out of the hallway, the ground suddenly collapsed!

But at the same time, pieces of floor formed by the condensation of soil quickly appeared, catching Su Fang and Hou An, not letting the two of them fall, and continuing to walk inside.

During the whole process, Hou An was stunned, numbly followed Su Fang, and his brain was blank!

Whether it's a wall panel or a floor, it's not a mechanism, but a temporary creation of the "dungeon of the earth" that Su Fang used to cast witchcraft and use it as a transition!

This kind of miraculous means directly subverted Hou An's three views.

At this moment, there was no thought in his brain, like a walking corpse, with Su Fang, through the Yongdao, to a huge underground space.

The whole space is hemispherical.

At the apex of the dome, a basin-sized night pearl sprinkled dazzling light, illuminating the vast underground space and every corner.

On the smooth walls all around, there are strange lines everywhere.

And on the empty ground, there are also five strange formations.

The five arrays with a radius of thirty meters intersect each other, like pentagrams, occupying a huge space surface.

At the center of the intersection of the array, that is, the center of the circle of the circular ground, an old man wearing a Taoist robe, a mustache, and a Tai Chi bun is sitting cross-legged with his eyes closed.

Someone!

In the inner cave of the cave, there are actually people!!

Hou An, who had finally recovered from his dazed state, looked dumbfounded and dumbfounded again.

He ...... He ......"

Hou An trembled, trembled and stretched out his hand, pointing to the old man who was sitting on the ground.

"Rest assured, he's dead. ”

Su Fang glanced around, his eyes suddenly lit up, and he walked to the center of the closest array to him.

I saw a silver-white stone the size of a pebble, lying quietly in the center of the array, emitting a misty white light.

Su Fang squatted down, picked up the stone, and sensed it carefully, and the next moment, surprise appeared on his face.

"Sure enough, it's a power stone!"

"It's the energy contained inside, it's not as good as the energy stones produced in the center of Datou Island, the center of the market, and the stone tower!"

If it is said that the power stone flying out of the stone tower, the energy contained inside is 10. Then in this pebble-sized power stone, the energy brewing is only 1.

A tenfold gap!

Su Fang walked to the other formations, picked up the energy stone lying in the center of the formation, and thought at the same time, what is the reason for this?

This reason is not only the difference in concentration, but also the birth of the power stone!

The heaven and earth energy on this side of the earth was inadvertently brought over by Su Fang who shuttled between the two worlds.

No matter how high the concentration is, it is impossible to form a power stone in the cave in the belly of this mountain.

The only explanation is the formation diagram on the ground!

It was these five arrays that played a role, absorbing the energy of heaven and earth, reshaping, and condensing a new energy stone with a smaller concentration!

This explanation perfectly explains the reasons before and after.

But here comes the problem again.

That's these five formations, what kind of formation?

Why can it absorb the energy of heaven and earth and reorganize the power stone?

Who is the portrayed owner, the old man sitting motionless on the ground?

Su Fang, who picked up all the five small energy stones, walked towards the old man with questions.

Unexpectedly, just ten steps away from the old man, the old man's body, which was originally no different from ordinary people, suddenly turned into a pile of powder, including clothes and hair, and spread it on the ground.

Only a two-finger-wide bronze sword was left, placed on the ground in front of the old man's sitting position, protected from the impact of the air current.

The old man had been dead for an unknown number of years, and because of the special method and the closed environment, the body remained untransformed.

This kind of indisposition is not that the corpse does not decompose.

The inside of the old man's body has actually been corroded a long time ago, but there is no air flow to preserve it until now.

Su Fang walked towards the old man, and as soon as the airflow impacted, the old man immediately turned into powder.

Hou An didn't know, and thought it was a living person.

But Su Fang had super hearing, and when he listened a little, he found that the old man had no heartbeat at all, and there was no blood flow in his body.

Sitting in the center of the five formations, there is no difference between it and the clay body bodhisattva in the mountain temple!

It's just that if you die, you'll die, so you can leave a little useful information!

Books, bamboo sticks, iron sheets...... Nothing, just a bronze sword.

Su Fang picked up the bronze sword, blew off the dust on it, revealing the sword body without a trace of rust, and waved it, it was quite heavy, at least thirty catties.

The lines on the blade of the sword are quite mysterious, intertwined with each other, like pythons.

Although I don't know which dynasty the old man is, I can guess a thing or two through the bronze sword.

The bronze sword was not completely replaced by the iron sword until the end of the Western Han Dynasty.

Before that, the edge of bronze weapons was brilliant in all directions, for hundreds of years.

The bronze sword left by the old man, Su Fang roughly examined it, and the craftsmanship was extremely exquisite, and it was obviously born at the peak of bronze weapons.

Warring states!

Or rather, pre-Qin!

This old man is a figure from the pre-Qin period, and with the five strange formations on the ground, Su Fang reminds him of a group of people.

Qi Refiner!

The real pre-Qin Qi refiner did not refer to the alchemist who refined the elixir of life.

Fang Shi played with all kinds of metals and minerals, and in the end he played himself to death.

Pre-Qin Qi Refiners, that was the earliest batch of ancient cultivators!

It's not about cultivating martial arts, but about cultivating immortals, or cultivating truth?

In short, no matter what they cultivated, the pre-Qin Qi Refiners represented the cultivation world in the early Huaxia period.

At that time, the land of Shenzhou was also very full of heaven and earth energy.

It's just that the energy of heaven and earth slowly disappeared later, and the Qi Refiners also dissipated in the long river of history.

Eventually, it was replaced by martial arts!

Su Fang guessed that the old man was a pre-Qin Qi Refiner, and without believing in evil, he searched in the underground space several times, hoping to find the secret about the Qi Refiner.

It's a pity that I turned the entire underground space upside down, and I didn't find anything.

Because it's been so long!

Bronze swords can only be preserved because of their unique properties.

Other bamboo slips, pieces of iron, and cloth that can be used to record information have long since turned into powder over time.

Su Fang had no choice but to give up and spy on the secrets of the Qi Refiners.

It was the five arrays on the ground, and they were all recorded in the brain.

After coming out of the hole, by the way, the tunnel dug out by Hou An collapsed.

Say goodbye to Hou'an, drive back to Jiangnan Province, turn around Liusha City, and prepare to find Sun Zhenghe to check whether there is a record of the "Hundred Beast Gate" refining qi warriors in the first Qin.

Unexpectedly, as soon as the car entered the boundary of Liusha City, he received a call from Sun Zhenghe.

"Hey, senior brother......"

"Senior brother, something happened, someone broke through the 'innate' realm!"

What the?
