Chapter 583 Entering Deep Underground

The three people divided the Blackstone Mountain area into three areas, and each person was responsible for searching one area.

Song Wenfei flew to the west side of Black Rock Mountain and made sure there was no one around.

Five shadow Gu flapped their wings and flew out of his mouth.

These are all the shadow Gu he carries with him, and there is one shadow Gu he left outside the secret realm.

Five shadow Gu entered five different cracks.

Not long after, all five shadow Gu returned.

Song Wen learned from Shadow Gu that these cracks were not completely independent, but connected to each other.

Somewhere deep underground, there will always be caves, large or small, connecting these cracks.

The deepest exploration of the shadow Gu went more than thirty miles underground, but no purple salvia or traces of zombies were found.

"It seems that this purple salvia is not so easy to obtain, and the number of zombies is less than expected." Song Wen thought to himself.

At Song Wen's signal, the five shadow Gu looked for other cracks in the distance.

But each shadow Gu did not penetrate deeper than thirty miles. Beyond this distance, Song Wen would lose contact with the shadow Gu.

Song Wen was worried that if he went too deep, Shadow Gu would encounter third-level or even fourth-level zombies, and he would be unable to command Shadow Gu immediately, causing Shadow Gu to die.

Half an hour later, Song Wen searched the area he was responsible for and arrived at the center of Black Rock Mountain.

Zhuyin and Ziyun are already waiting here.

"Jiyin, have you discovered anything?" Zhuyin asked.

Song Wen shook his head.

He wasn't lying, he really found nothing.

"What about you?" Song Wen asked.

"We didn't find purple salvia either." Ziyun said.

"At what depth did the monks of your sect who entered the secret realm discover purple salvia at what depth?" Song Wen asked.

Ziyun said, "Most of them are found deep in the cracks. Occasionally, purple salvia can be found in the shallow areas of the cracks."

"It seems that we are out of luck." Song Wen said with some regret.

Then, Song Wen continued to ask, "What does fellow Taoist Ziyun plan to do next?"

As a member of the Liangyi Sect, Ziyun's understanding of the secret realm is far better than Song Wen and Zhuyin. Therefore, both Song Wen and Zhuyin would ask for her opinion.

Ziyun said, "In the current situation, there is no other way but to venture into the depths of the crack. Judging from the past situations of obtaining purple salvia, the probability of purple salvia appearing in the central area is the highest. We will start searching from the cracks nearby. "

Song Wen and Zhuyin nodded and agreed with Ziyun's decision.

Ziyun looked around, found the widest gap nearby, and flew in.

Song Wen and Zhuyin hurried forward.

As the depth increases, the light gradually becomes dimmer until it is completely dark. At the same time, the corpse energy becomes more and more intense, and the perception distance of spiritual consciousness becomes shorter and shorter.

When it goes more than fifty miles underground, the spiritual consciousness can only perceive a few miles.

"You two, if you have any means of investigation, bring them out. Don't hide them. If one of you is not careful and is attacked by a fourth-order golden corpse at close range, no one among the three of us can take advantage of it."

Ziyun looked at the dark and narrow crack under his feet and reminded him.

Hearing this, Zhuyin did not hesitate at all. He raised his hand and waved, and a third-level early-stage ghost king appeared out of thin air.

Seeing Zhuyin's actions, Song Wen called out his mid-level third-level ghost king without hesitation.

"Isn't your Wuji Island good at refining corpses? Why are you raising ghosts instead?"

Ziyun joked casually. She patted the spirit beast bag on her waist, and a late third-order spirit beast suddenly appeared.

This spiritual beast looks like a crocodile. It is seven feet long, has a flat body, short limbs, is covered with dark brown scales, and has a sharp, diamond-like horn on its head.

"This is the spiritual beast I specially prepared for this trip to the secret realm. It's called the Earth-walking Dragon. It's very good at drilling into the ground."

Ziyun took the initiative to introduce them, seeming to show Song Wen and Zhuyin that she valued this trip.

Tu Xinglong drilled directly into the depths of the crack to clear the way for the three of them.

The two ghost kings, one on the left and one on the right, guarded both sides of the crack.

After the three of them descended for more than ten miles, they stopped again.

The gap below is too narrow to allow people to pass through.

They have searched all the areas where this crack can be found, and still haven't found the purple salvia.

Ziyun suddenly raised his hand and pointed to the right.

"Ten miles ahead, Tu Xinglong discovered a cave that seems to lead to a deeper place. Do we want to continue going deeper?"

"Keep going deeper!" Song Wen said without hesitation.

They have been searching for an hour in the Black Stone Mountain, and they haven't seen even a trace of purple salvia.

Song Wen finally understood that if he wanted to get purple salvia, he had to take risks.

Under the leadership of Ziyun, the three of them came to a cave that sloped downward.

The cave is very narrow and can only accommodate one person.

Moreover, there are some fresh traces of broken stones in the cave. They should have been recently widened by the earth-walking dragon for the passage of three people.

The three of them entered the cave one after another.

Ziyun led the way, Zhuyin followed in the middle, and Song Wenduan followed.

There was an earth-walking dragon exploring the way ahead, so the three of them didn't encounter any accidents.

After descending for more than ten miles, the cave suddenly became spacious, already several feet wide.

"This is simply a natural blessed place for corpse refining." Zhuyin sighed in a low voice.

The corpse aura here was extremely strong, compressing the perception range of Song and Wen to less than two miles.

The cave is not a smooth path, but full of strange rocks.

Ziyun's voice suddenly became a little excited.

"Tu Xinglong discovered a purple salvia."

When Song Wen and Zhuyin heard this, a hint of joy flashed across their faces.

Wind blew under the feet of the three of them. After turning a few corners, the cave suddenly widened to dozens of feet.

In a corner of the cave, there is a half-foot-tall spiritual grass growing.

The spirit grass has three jet black leaves.

After Ziyun carefully observed the spiritual grass for a moment, he said softly.

"It is indeed purple salvia, and it has been used as medicine for three hundred years."

Purple salvia can only grow one leaf every hundred years.

Ziyun turned his head and looked at Song Wen and Zhuyin.

"This purple salvia belongs to me, do you two have any objections?"

Before Zhuyin had time to speak, Song Wen spoke first.

"Fellow Taoist Ziyun has contributed the most along the way. This first purple salvia plant should belong to you. If we encounter purple salvia again in the future, Taoist friend Zhuyin and I will allocate it again."

Seeing that Song Wen and Zhuyin had no objection, Ziyun came to Purple Salvia. She knelt down and reached out, ready to uproot it.

Song Wen had a look of caution on his face, his eyes were fixed on Ziyun's movements, and he took two steps back without leaving any trace. The evil spirit of Guiyuan surged in his body, ready to be summoned at any time.

Where purple salvia grows, the corpse aura is obviously stronger than in other places. This makes Song Wen, who saw purple salvia for the first time, uncontrollably wary.
