Through the crack of yin and yang, the white night reached the underworld below the Arctic land.

As expected, the underworld here is also a frozen and cold place, and below is a large area of frozen plateau, and the yin qi and dead qi floating and tumbling above are extremely thin.

This is the only place where there is no yin and dead qi piled up into black clouds and canopies in the sky in the white night in all parts of the underworld.

Above the sky of the underworld, there is only very thin yin qi and dead qi wafting.

As for the frozen plateau, ghosts and demon cultivators, they didn't see a single shadow.

It seems that he can't stand the cold and cold here, and he doesn't want to come here.

This is convenient for Bai Ye, and he doesn't have to worry about the safety of the 'immortal water' in the yin and yang cracks, even if it is an advanced 'immortal water', it has not been able to attract a ghost or demon cultivator, which shows the loneliness of this place.

Bai Ye's figure flew away, patrolling around the frozen plateau to make sure that there was no threat, before returning to the Yin and Yang Rift and piercing back to the Yang Realm.

After passing through the West Pole and facing a huge crisis like the Heavenly Ghost Wuxiang, this extreme northern land was calm at this time, not to mention the threat, and he couldn't even see a ghost, which made Bai Ye feel a little unaccustomed for a while.

However, there is no threat from ghosts and demon cultivators, and safety is the best, so he doesn't have to bother and work here, he can directly go to the last central place to check the situation of the last earth immortal materials.

And after he finished checking the final 'immortal soil', determined the nature and attributes of the five elements immortal materials, and then based on his own perception of yin and yang, life and death, and reincarnation, he should be able to roughly determine the next refining direction of the immortal weapon's 'reincarnation'.

Even if you can't come up with the most precise and detailed refining steps and plans, you can at least determine a direction.

At that moment, he returned to the yang world, saw that Senior Sister Qinglian was still sleeping in the pond, and did not disturb the other party, directly called Taiyuan Palace and teleported back.

And after the white night left, the green lotus in the pool of water on the iceberg turned a few times slightly, as if looking for a more suitable position for sleeping, and fell into a deep sleep again.

Bai Ye borrowed the Taiyuan Palace, teleported again, and went to the last place where the earth-walking immortal materials were refined.

This place is indeed in the very center of the Xuanchen Realm Continent, and it can be called the middle pole land.

Speaking of which, Bai Ye never knew where the most central place of the continent was, and how the sect determined the location of this central place.

And after he teleported through Taiyuan Palace and arrived at the so-called 'Middle Pole Land', he found that he was just an ordinary small mountain.

The height is less than 1,000 zhang, stretching less than 100 miles, neither majestic nor precipitous, it can be described as featureless.

And its location, but in the Qingyang River to the west of the plateau, the Azure Plateau to the east, when Bai Ye took the shuttle to the Shenwuhui Azure Plateau, it seemed to pass by from here?

He wasn't sure.

However, this land of mountains with no features, the so-called 'Middle Pole Land', has been invaded by ghosts and demon cultivators, forming a netherworld and demon land where ghosts and demon cultivators converge, which can be seen clearly.

Bai Ye didn't doubt anymore, and according to the information transmitted by the sect, he walked towards the middle of the mountain range, a mountain pass.

When he arrived at the mountain pass, Bai Ye took out the identity token of the sect, and his mana was aroused.

Immediately, a light shot out of the token and landed on a cliff face in the col.

I saw a change of light and shadow, and an entrance quietly appeared on the cliff wall.

White Night strides into it, it is a cave, leading straight down, I don't know how deep.

Bai Ye flew all the way forward, all the way down, and gradually felt that there were hundreds of zhang deep, thousands of zhang deep, and even ten thousand zhang deep, and as he continued to go deeper, he gradually felt that the aura of the earth around him was constantly rising, full of thick and mysterious aura.

As he flew downward, his identity token hung on his body, flashing with aura, echoing some of the arrangements in the surrounding caves from time to time.

That's to verify his identity, the identity is correct, and the authority allows it, and then he will be released!

Otherwise, if there is anything wrong, many deadly traps and attacks may erupt at any time on the surrounding caves!

It can be seen that the Wanbao Sect has the strictest protection of this 'middle pole land' where the earth is refined, and it is also the deepest hidden.

Finally, when he didn't know how many thousands of miles he had flown down, it felt like the depth of the 'sea ruins' when he dived in the East China Sea.

The earthy aura around has turned into substance, and wisps of Xuanhuang aura float around.

Although it seemed to be just a wisp of breath, Bai Ye could clearly feel the terrifying weight contained in it.

That breath is comparable to the weight of a mountain.

These Xuanhuang breaths can already be regarded as spiritual materials, and at least they are ground-level spiritual materials.

White Night finally saw its destination.

It was a floating island surrounded by a dark yellow aura.

Bai Ye could see that that floating island was the 'immortal soil' that was tempered here.

On the floating island, there is a white jade palace.

As if sensing the arrival of the white night, two figures came out of the white jade palace.

An old man with a short body and a stiff back, that is the 'Dixing Zhenjun' of the Demon Department of the Sect, and it is said that the body is a pangolin, which may have been discovered and excavated by him.

And the other is a big man with a yellow face, but he is the 'Hun Cheng Zhenjun' of the sect's instrument department, what kind of spiritual treasure is the body, Bai Ye does not know, but from the breath around his body and the surrounding Xuanhuang breath, and even with the entire immortal road are almost fused together, very consistent, regardless of each other, it can be judged that it must be a spiritual treasure of the earth.

Bai Ye flew away, landed on the floating island, saluted the two, and said, "Bai Ye has seen two senior brothers. ”

The two returned the salute and said, "I've seen Senior Brother Bai Ye." ”

After the two sides saluted, Bai Ye looked around and said with a feeling: "Why do these surroundings give me a very familiar feeling, it seems that I have been here before, but I can be sure that I have never been here!"

Hearing this, the Demon Sect Zhenjun stroked his beard and said with a smile: "Then if you want to come to the junior brother, you must have been to the East China Sea Ruins!"

"Not bad!" Bai Ye nodded and said, "I have been invited to participate in the East China Sea Jiazi Tide and enter the East China Sea Sea Market. ”

"Huh......" Bai Ye said, and suddenly he felt all the feelings, and said carefully: "Speaking of which, the feeling I feel here seems to be really similar to that in the East China Sea ruins." ”

"It's not the terrain, it's not the landforms, it's the ...... Breath, Spirit...... It's a rhyme!"

"Haha...... That's right!" Dixing Zhenjun said with a smile: "In the East China Sea, it is called the sea ruins, and this place is called the 'earth ruins'!"

"Earth Ruins?" Bai Ye was stunned for a moment, then reacted and said, "This is also connected to the 'Heaven and Earth Root', which leads directly to the origin of Heaven and Earth?"
