Yun Feiyang personally led the 'Black Mountain Sanren' to inspect the place and formation materials where the Tribulation Formation would be arranged.

Li Yunlong could see that Yunlang Ancestor should have been preparing for the tribulation for many years.

There is only one thing that Li Yunlong doesn't quite understand, after all, this Yunlang Ancestor is the great worship of the Yang family, why does it seem that his means of crossing the catastrophe should avoid the Yang family?

If it was with the assistance of the entire Yang family, with the old man's solid and terrifying true yuan mana, he should have tried to advance a long time ago.

"I guess there's some bullshit going on inside. Li Yunlong finally made a characterization of the complicated relationship between Yunlang Ancestor and the Yang family.

In the early stage of the blood infancy, the monk advanced to the middle stage, and the thunder robbed the old cow.

Therefore, the requirements for the most important means to assist in resisting the Thunder Tribulation - the Tribulation Circle, are very high.

The magic circle needs to be extremely strong, and the flow of spiritual power must far exceed the breadth and smoothness of ordinary formations.

If the materials allow, it is best to let the circle have some self-repair ability.

Then Li Yunlong began to move, and the formation template he chose came from the memories of the scattered people of Montenegro.

It is the extinct three-star sect's secret tribulation formation - the Tiangang Earth Evil Array.

This formation requires refining seventy-two dragon piles and driving them deep underground to intercept the spiritual power of one side of the water and soil.

It is also necessary to refine thirty-six Sky Survey Banners to draw the sun, moon, and star brilliance.

The Tiangang Earth Evil Array can not only be used to cross the tribulation, it can be disassembled and taken away, and it is a big killing weapon to arrange it in a suitable place.

However, this formation is very difficult to refine, not to mention, the labor intensity is still very large.

It was enough to refine one hundred and eight array weapons, which was really a big business.

As the days passed, Li Yunlong passed through the confirmation of the inheritance of many formations in his hands, making his achievements in the formation go further.

On this day, when Li Yunlong was refining the last of the seventy-two Zhenlong piles, a transmission note arrived at the door of the quiet room.

"The seniors are fine, and the juniors Bai Yu have important things to discuss. The words left in the transmission note made Li Yunlong feel that the other party seemed to be cautiously touching.

The door of the ashram opened, and an old monk with white hair and cultivation who was only in the late stage of the blood qi stage walked in tremblingly.

Li Yunlong's brows furrowed slightly, this old and unbearable monk Shouyuan was about to run out. He was even worse than Yun Lang Ancestor.

What's more important is that Li Yunlong 'smelled' a very peculiar smell from this person.

It wasn't the breath of a serious monk, it was a bit like the faint smell of a blood beast.

"Hello senior!"

"What's the matter, I'm busy now!" Although he found some special places, Li Yunlong didn't have much to do to get to the bottom of it.

"Yes, the juniors are the stewards here. I just came back today, and I heard that the senior prestige paid a special visit...... The little old man wants to exchange for the opportunity to advance to the second order that you have. Originally, he planned to say it in detail, and add foreshadowing to set off his pitiful experience, so as to win the sympathy of this formation master.

I don't want this Montenegrin scattered person to deal with it like this!

So Bai Yu also said his meaning directly.

"Three chances can also cultivate at least two Blood River Stage cultivators, and there ......are many people in my Seven Star Building who need this immortal relationship," Li Yunlong did not directly refuse, but he also meant to refuse.

The juniors naturally know this, so the juniors prepared a gift and asked the seniors to smile. Bai Yu seemed to have made the most resolute decision, and he took out an old spirit wood box that was one foot square with a twitching face.

Li Yunlong's pupils couldn't help but shrink, this was the source of the abnormal aura on the other party's body.

Under Li Yunlong's pupil technique, he could only see that there was a faint layer of pale white smoke in the old spirit wood box.

A light and cool aura was immediately born in the quiet room where Li Yunlong was temporarily staying, and after taking a deep breath, the whole person felt an indescribable comfort.

"The power of Taiyin!" Li Yunlong gave himself an answer in his heart.

The aura on the old man's body was weak just now, and Li Yunlong didn't accurately determine which category the aura on his body belonged to, and now that the main man appeared, Li Yunlong could easily guess it.

"This is a treasure that the younger generation obtained many, many years ago, and after years of research by the younger generation, this thing can condense three or five drops of spiritual liquid on a full moon night. That kind of spiritual liquid is very similar to the legendary emperor who meets once in sixty years!" The old man also looked proud and ...... Reluctant.

After all, this thing had helped him a lot in the early stages of his cultivation. If you get along for too long, it's so easy to give up.

"Done! Daoyou make an oath of demons. Li Yunlong opened the old spirit wood box, and the items inside it were immediately reflected in his mind.

It wasn't the imaginary chunk of ore, it wasn't a kind of spiritual flower, it was a very old small, thick-walled stone jar without a lid.

A few pearl-like droplets of crystal clear water rolled at the bottom of the object.

This was deliberately left by the other party, the purpose was to let Li Yunlong see the value of this thing.

When Bai Yu heard the oath that made him a demon, his heart was relaxed.

This shows that the other party has no intention of killing him, this small stone jar has been in his hands for a long time, and he has not made a move, except for reluctance, another point - safety, not guaranteed.

If it weren't for Bai Yu knowing the identity of the 'Black Mountain Sanren' array mage in front of him, his longevity had reached the end and this was on his own land, he would definitely not have taken it out.

The truth of guilt is also applicable in the Heavenly Blood Realm.

Therefore, Bai Yu made a great oath very simply.

"It would be better if this Montenegrin man could also make a vow not to pass on secrets. Bai Yu still thought to himself, but the huge difference in status and strength between the two sides made him dare not make such an 'excessive' request.

"Take this thing, it contains enough spiritual liquid to hit the bottleneck at least twice. Li Yunlong's approach directly surprised the monk named Bai Yu.

"Is this the Earth's Heart Spring?" he couldn't believe it.

"That's right, I was in the nearest location when the Earth Core Spring Spiritual Liquid erupted, and occasionally picked up some. Li Yunlong's heart was not flustered or beating.

"That's right, it's really the spiritual liquid of the Earth Heart Spring!, the juniors, thank you for the grace of the seniors to continue their lives!" Don't look at his old age, he almost jumped up in excitement when he suddenly encountered such a good thing.

He said goodbye and left in a hurry, each step as if he was stepping on a cloud.

It's fluttering, and I feel that my bones are lighter.

Li Yunlong closed the prohibition, and then excitedly picked up the old and broken thick-walled stone jar and studied it carefully.

This thing has a peculiar effect, and although the spiritual fluid produced cannot improve cultivation, it can nourish the soul and heal wounds.

It's very rare!
