"Dad!" Seeing the old man's back, Ling Zhanxuan and the three of them hurriedly stepped forward and saluted.

"Grandpa!" Ling Yunfeng hesitated for a moment and bowed slightly to the old figure, from his memory, he also knew that this person was his grandfather, Ling Cang, the old patriarch of the Ling family.

"You're here, come in with me first. Ling Cang looked at Ling Yunfeng with a kind face and smiled slightly, then walked to a stone wall, formed a handprint, and then threw a few streamers into the sky.

"Boom!" As several streams of light flashed in mid-air, the entire stone room suddenly trembled, and suddenly the stone wall made a loud bang, and countless limes fell, as if the entire secret room was about to collapse.

At this time, under Ling Yunfeng's stunned, a stone door suddenly appeared under the floor in the center of the stone room, and the stone door slowly moved open, instantly revealing a stone passage on the floor that could accommodate two people to enter at the same time.

"Formation?" Looking at this strange scene, Ling Yunfeng's eyes showed a look of surprise, and he said in a low voice.

After this period of research on the Heaven Refining Treasure Record, Ling Yunfeng had also dabbled a little in the formation method, so he could guess that Ling Cang was opening a formation just now.

"Oh, can you even see that this is a formation? I didn't expect you to also study formations, it seems that your back is really not simple. Ling Cang glanced at Ling Yunfeng with some surprise, and then didn't ask anything, beckoned to everyone, and walked directly into the secret passage.

"Let's go inside. Ling Zhanxuan and the three of them also glanced at Ling Yunfeng with some surprise, if they hadn't studied the formation, it would be impossible to see that it was the formation just now, you must know that they didn't know what was going on when they saw this situation for the first time.

Immediately, the people entered the cave one after another, and the passage of the cave was so narrow that only one person could pass through.

The stone walls on both sides of the cave also looked rough and damp, and the passage continued downward, with no end in sight, and it was extremely dark inside, and I don't know how deep it was.

In this gloomy cave, although the stone walls on both sides of the cave are inlaid with many moonstones, they are only barely illuminated.

The group walked quietly in the cave, not saying anything along the way, until they reached more than two hundred meters, Ling Yunfeng suddenly felt that there was a faint energy fluctuation in this cave, and under careful induction, he found that the concentration of spiritual energy in this cave was much stronger than that of the outside world.

After walking a distance of 100 meters again, a faint smell of medicine entered Ling Yunfeng's nose, Ling Yunfeng raised his eyes and saw that there were many elixirs planted on both sides of this cave, and the deeper he went into the bottom of the cave, the more elixirs grew, and the more lush they grew.

"I didn't expect that there was such a place in the Ling family. Ling Yunfeng said in surprise in his heart, but when he saw that Ling Zhanxuan and the others didn't mean to speak, he didn't ask.

After traveling a few hundred meters again, the group came to a stone wall, at this time, the aura of this cave was already rich to the extreme, estimated to be about five or six times that of the outside world, and this aura seemed to be pulled by something, violently churning and surging.

A rich energy fluctuation permeated this space, causing the martial energy in Ling Yunfeng's body to stagnate a little, and there seemed to be a strange energy in this air.

This energy breath entered his body with his breathing, and suddenly Ling Yunfeng felt indescribably comfortable, the flesh and blood in his body had a feeling of vitality, and the blood in his body also seemed to be under some kind of connection.

"Vitality!" Ling Yunfeng muttered, his gaze becoming extremely surprised.

He had wandered between life and death many times, and he quickly recognized that the strange energy in the air was actually the power of vitality, which could quickly restore the damaged tissues in people's bodies, and it was not impossible to bring the dead back to life even if it was a little more terrifying.

I just don't know how there is a vitality in this cave, although this vitality is extremely meager, but it is real in the air.

"Go in first, I know you have a lot of questions, I'll tell you when I get in. Ling Cang looked at Ling Yunfeng's puzzled expression and said, and when the words fell, he pressed directly on the stone wall.

"Boom!" As Ling Cang's hand pressed, a loud bang suddenly sounded on the stone wall, and then I saw a stone on the stone wall in front of me moving slowly, and a hole that only allowed one person to pass through quickly appeared on the stone wall.

With the appearance of the entrance to the cave, a dazzling green light suddenly flashed out, and the strong light made Ling Yunfeng close his eyes for a while, and only slowly opened his eyes after half a sound.

Immediately, I saw a cave mouth with a dazzling green light appear in front of me, and bursts of white mist gushed out from the cave entrance, just like the cave of an immortal, and there was a sense of etherealism.

Picking the tip of his nose and gently inhaling a few wisps of white mist into his body, Ling Yunfeng felt a burst of refreshment in his body, and even the Heavenly Refining Technique was automatically running.

A moment later, the chance white mist that was inhaled into the body turned into a trace of pure martial qi that filled the veins between the veins.

"This is ......, it's aura, this white mist is aura. Ling Yunfeng was surprised in his heart, and then he was a little shocked, the aura had turned into a liquid state, so how rich was this aura.

"Come in. Ling Cang beckoned and walked into the cave first, followed by the three Ling Zhanxuan brothers. Ling Yunfeng hesitated for a moment, and followed in with curiosity.

Through the entrance of the cave, a cave space with a size of 100 meters suddenly appeared in front of everyone.

The cave was illuminated by a strange green light, and the rich white mist transformed by the aura was churning and surging in the cave, like a sea of clouds. The white mist was so thick that even objects three meters away could not be seen clearly.

"Hey, is that ......?" Ling Yunfeng's gaze first noticed the center of the cave, where there was a pool of ten meters in diameter, the pool was filled with turquoise liquid, but this liquid was as crystal clear as jade, blooming with bursts of soft green light, and the pool was filled with a rich aura white mist.

In the center of the pool, there is a turquoise lotus plant, and the whole lotus flower is crystal clear, like jade.

"What kind of elixir is that?" Ling Yunfeng muttered suspiciously, he didn't have any information about this emerald green lotus in his memory.

Ling Yunfeng could feel that a trace of vitality power was permeating from this pool, and there seemed to be a strange aura in this vitality power.

This aura is ancient and vicissitudes, under this breath, Ling Yunfeng felt that the martial qi in his body had completely stagnated, and he couldn't raise the slightest courage to resist, and a sense of insignificance arose.

"Want to know what it is?" At this moment, Ling Cang looked at the turquoise lotus flower in the center of the cave and suddenly spoke.

"Hmm. Ling Yunfeng nodded subconsciously.

"That's the heart of the Occult Spirit. Ling Cang said.

"Xuanling Heart, what is that?" Ling Yunfeng muttered suspiciously.

"You don't have to know what it is, it doesn't do you any good now. As long as you know that this is one of the most precious treasures in heaven and earth, countless strong people will fight for it when they know it. Ling Cang said, "This treasure is a combination of vitality and destruction. ”

"The most precious treasure in the world...... Combining vitality and destruction?" Ling Yunfeng muttered in a low voice, his gaze extremely shocked.

"See these elixirs?" Ling Cang said, pointing to the dense elixirs in the cave.

"Hmm!" Ling Yunfeng nodded stunnedly and said, there are many medicinal materials that are extremely precious in the outside world growing in this cave, and the growth of each elixir is several times better than that of the outside world, presumably because of the extremely rich aura in this cave.

"These elixirs may take hundreds of years to mature in the outside world, but this Xuan Ling Heart is placed here, constantly pulling the spiritual energy of the outside world to gather here, so that the spiritual energy of this cave is several times richer than that of the outside world.

Under the grace of this treasure, these elixirs can mature in almost a short period of ten years, and the medicinal power of the elixir has not weakened in the slightest, but has greatly increased. This is the vitality of this treasure. Ling Cang said.

"What?" Ling Yunfeng said in surprise, he didn't expect this treasure to be able to shorten the maturity of the elixir.

I'm afraid that this alone is enough to make many people crazy, you must know that some rare elixirs are very beneficial to cultivation, but the higher the level of the elixir, the longer the general maturity period, which leads to the scarcity of high-level elixirs.

"As for destruction?" Ling Cang said slightly, and then his dry palm slowly poked out, directly ingesting a stone of dozens of catties in the air and throwing it towards the turquoise pool.

Just when Ling Yunfeng was puzzled by Ling Cang's actions, the boulder suddenly solidified just as it was about to touch the surface of the turquoise liquid, and then suddenly burst open with a pop under Ling Yunfeng's stunned eyes, and instantly dissipated into the air as ashes.

"This ......" Ling Yunfeng was stunned for a moment, and immediately gasped, directly turning a huge stone into ashes, this power is too strong, right? This at least requires the strength of the Martial King or above.

"Well, there are some things I should talk to you about. Ling Cang looked at Ling Yunfeng's surprised expression, looked a little satisfied, smiled slightly, and then said, "Do you know how strong our Ling family was when it was the strongest?"

"Isn't it Ling Tianfeng's ancestor, the strength of the Martial Emperor's powerhouse?" Ling Yunfeng said, this was also what he heard casually when he worshiped his ancestors that day.

"No, Ling Tianfeng Ancestor is only the first generation of Ancestor who led our Ling Family to Qingfu City, not the strongest Ancestor of our Ling Family. Ling Cang shook his head with a smile and said, and then his face couldn't help but show a hint of pride, and he said with some excitement: "In fact, our Ling family was stronger than the power of the Soul Martial Academy at its peak, and there are not many forces or families in the entire Xuanling Continent that can compare with our Ling family.

And the first generation of the Ling family's ancestors was one of the strongest powerhouses in the entire Xuanling Continent. At that time, there was almost no one in the entire Xuanling Continent who could compete with the ancestors, but later due to some reasons, the ancestors unfortunately fell, and the Ling family gradually fell, and after thousands of years, it finally became what it is now. ”

In the end, Ling Cang's face couldn't help but show a touch of sadness, thinking about how powerful the Ling family was back then, how proud, proud, and passionate every child of the Ling family was, but he didn't expect that now he had fallen to such a state, how could he not let every child of the Ling family sigh.
