The toxins of the Tianxiang Stone Fetal Stone can easily be resisted by Lin Yi'an's current cultivation.

Feng Tian should have just inhaled the toxins emitted by the birthstone that day, if he really came into contact with the placenta stone, then he would have died a long time ago, and he couldn't wait for Lin Yi'an at all.

The ground around here must be covered with ordinary celestial stones.

Lin Yi'an held a hoe in his hand and began to dig around the fetal stone, he wanted to see what the quality of the Tianxiang stone under the ground was.

After all, he had only bought a piece of Tianxiang Stone from Chen Lihua before.

With the cultivation of the seventh layer and his Dao Monarch body, his arm strength is far beyond that of ordinary people.

He wielded his hoe very quickly, and it didn't take long for him to dig more than two meters into the ground.

As far as the eye could see, red stones of various shapes appeared.

In the darkness, the surface of these red stones was all surging with a faint golden light, and reaching out to touch the surface of these Tianxiang stones, Lin Yi'an could be sure that the quality was much better than Chen Lihua's Tianxiang stone before.

The piece of Tianxiang stone obtained by Fengtian should have happened to be formed on the ground, so compared to the underground, the quality is much worse.

After seeing the quality of the Tianxiang Stone here, Lin Yi'an was about to leave Black Dragon Mountain, but when he was about to fill the soil back, he vaguely felt that something was wrong.

It was a subtle instinct that something in the depths of the earth seemed to draw him in.

Although he didn't have Daojun's cultivation now, he would never have this feeling for no reason.

After a moment's silence, he prepared to dig deeper to see what was going on.

Lin Yi'an bypassed the Tianxiang Stone under the ground, wielding a hoe and digging down, the further down, the Tianxiang Stone was no longer so dense.

Three meters.

......

Five meters.

When digging to a depth of more than six meters, there was no Tianxiang Stone anymore, Lin Yi'an's intuition became stronger and stronger, and the hoe in his hand did not stop.

"Bang dang!"

With a crisp sound of metal colliding, I saw pieces of white crystals appear under the ground.

Each piece of this crystal was only the size of a child's fist, but a smile suddenly bloomed on Lin Yi'an's face.

Two words came to mind: "Source Stone".

The source stone is a product of the ancient world, which contains pure and flawless source qi, and cultivators can absorb the source qi in the source stone to cultivate.

And the source stone is also the currency in circulation in the ancient world.

Lin Yi'an didn't expect that there would be a source stone in the Black Dragon Mountain, and it seemed that his previous intuition was not wrong.

It's just that after taking a closer look, there is no source qi fluctuation in this piece of source stone, what is going on?

The white source stone is a low-grade source stone, and it is also the lowest-grade source stone, but for Lin Yi'an now, even a low-grade source stone is a scarce resource.

Lin Yi'an put his palm on the white source stone, he closed his eyes and sensed it carefully, and his brows were furrowed deeper and deeper.

After he opened his eyes, the hoe in his hand continued to dig downward, and there were more and more lower-grade source stones in his eyes, but without exception, each lower-grade source stone had no source qi fluctuations.

Under the Tianxiang stone mine, there is actually a first-class source mine, and the so-called first-class source ore is a mine with only low-grade source stones.

But this primary source mine seems to be a dead source mine.

As the name suggests, the Dead Source Mine is that all the source stones are in a closed state of source qi, but Lin Yi'an is the youngest Dao Monarch in the Ancient World, this kind of thing is not difficult for him to solve, as long as he finds a way to activate this dead source mine, then the source stones in the source ore will recover a certain amount of source qi.

Of course, even if the Dead Source Mine is activated, the source qi contained in the source stone will be greatly reduced, and it will definitely be worse than the real low-grade source stone.

Fortunately, there is a whole source mine here, even if the quality has dropped a little, but it is better than the quantity, and the lower grade source stone will be of great help to him to improve his cultivation now.

Originally, he planned to use jade to arrange the condensing source array, so that although the condensing source array could be arranged, but it did very little, and now that the source stone was discovered, it was natural to use the source stone to arrange it.

It's just that it's also very troublesome to activate the Death Source Mine, and there may be a lot of movement when the time comes, so it's imperative to buy the entire Black Dragon Mountain first, and it's best to buy all the land around the Black Dragon Mountain.

It is most appropriate to leave the matter of buying Black Dragon Mountain to Yuan Shan, and now he can only wait for a few days, and he can just prepare for the activation of the Death Source Mine.

As the saying goes, trickle down into a river.

A complete first-grade source mine, no matter how bad it is, the production of low-grade source stones is at least thousands, if you encounter a first-class source ore with a higher output, the lower grade source stones may even reach twenty or thirty thousand.

After having a plan in his heart, Lin Yi'an quickly buried the excavated soil back, he was not too worried in his heart, no one on the entire earth except him for the Tianxiang Stone and the Death Source Mine should understand.

Tonight's trip was really not in vain, as long as this first-level source mine was reactivated, his cultivation speed could be accelerated several times.

Lin Yi'an took the hoe and ran towards the foot of the mountain again.

It's late at night.

Black Dragon Village Feng family.

All the green spots on Fengtian's body have disappeared, the toxins in his body have been completely discharged, and the whole person is radiant and can get out of bed and walk on his own.

Yuan Shan, Feng Erhu and Chen Lihua sat and waited, they had no intention of sleeping at all.

"Erhu, you go up the mountain with me to find the benefactor, it's not a way for us to wait at home, in case the benefactor encounters danger on the mountain, I will feel guilty for the rest of my life. Feng Tian said.

Feng Erhu agreed with his father's words, and he was ready to go to Lin Yi'an with Feng Tian.

Yuan Shan stood up suddenly, he looked outside the gate of the Feng family, walked out quickly, and said, "Look, the immortal master has returned, I said you don't have to worry." ”

Fengtian also ran out and asked eagerly, "Benefactor, are you okay?"

Lin Yi'an put the hoe next to him casually and said, "What can I do?"

"By the way, if I want to buy Black Dragon Mountain, and the land around Black Dragon Mountain, will you villagers of Black Dragon Village agree?"

Fengtian looked happy, "Benefactor, a few years ago, the city wanted to let us move out of Heilong Village, but there were some old antiques that had to stay here, and then the development outside was changing with each passing day, and many young people in the village were complaining, but because of the previous delay, now we want to move away and no one cares." ”

"Benefactor, if you buy the land near Black Dragon Mountain, as long as the price you give is reasonable, I believe that the people in our village will definitely have no opinion, many young people in the village are clamoring to leave this ghost place all day long. ”
