C150 Inhale the Black Yellow Qi

Ye Feng observed the stone door for a while before slashing at it with his sword.

"Clang!" A huge force bounced back from the stone door, and the sword almost slipped out of his hand. The huge rebounding force made Ye Feng's wrist feel numb.

"Hmm?" Ye Feng immediately frowned.

Cold air began to leak out from the gap of the stone door, causing the temperature of the entire cave to drop significantly.

The little thing trembled in Ye Feng's arms.

"Yes, it is indeed very cold!" Ye Feng had never felt such an extreme cold temperature before, as if his strong muscles had no hindrance. The extreme cold directly stimulated his bones, and even his internal organs. His entire body was cold.

"Looks like I need to use the Profound Qi to protect myself!" Violent inner strength circulated all over his body, and Ye Feng's body was instantly covered by the Profound Qi.

"I feel much better now."

Ye Feng carefully looked at the stone door in front of him. At the crack of the stone door, there was a large amount of white fog seeping out. This was Spiritual Qi that had been condensed to a certain extent.

At this moment, Ye Feng could feel that the earth veins in his body had become restless.

"How could this be?" Although the earth veins could absorb the Black Yellow Qi, ever since Ye Feng opened the earth veins, he had rarely absorbed the Black Yellow Qi from the outside world, and only things that contained the Black Yellow Qi had appeared. The earth veins would react.

In the next moment, Ye Feng felt that in his Dantian, yellow light spots passed through the whirlpool of the earth vein and floated into Ye Feng's Dantian.

Then, these yellow light spots immediately followed the Profound Qi in his body and moved along the other meridians. Finally, they were absorbed by his body.

Black Yellow Qi!

Ye Feng was delighted in his heart. He did not expect that the spiritual Qi that leaked out from the gap of the stone door actually contained Black Yellow Qi.

Looking at the stone door in front of him, a light flashed in Ye Feng's mind. Then, he walked to the front of the stone door and placed his hand on the stone door. After that, he circulated the earth vein with all his strength.

"Riiip! Riip!"

A majestic spirit energy was instantly absorbed by the stone door. There was quite a lot of Black Yellow Qi within.

What a rich Black Yellow Qi.

Ye Feng was very happy. He knew that the Black Yellow Qi was a special energy that was formed when the heaven and earth was just opened. It was rare to find it in the Immortal Dust Continent now.

There were two possibilities for the Black Yellow Qi inside the stone door. The first possibility was that the stone door itself contained the Black Yellow Qi, and the second possibility was that it was sealed by a peerless expert.

No matter what the possibility was, Ye Feng couldn't be bothered with it. His main task right now was to absorb this spiritual energy to improve his Profound Qi cultivation, and the Black Yellow Qi could strengthen his body.

It was said that in the ancient era, those heaven-defying gods could borrow the Black Yellow Qi to cultivate an indestructible body.

Ye Feng started to absorb madly.

The Creation Heavenly Scripture was a rare heaven-defying skill even in the ancient era. The speed at which it absorbed the spiritual Qi was incomparable to any ordinary skill.

There were three factors that affected the speed at which a cultivator absorbed the spiritual energy. The first was the cultivation technique of the cultivator itself, the second was its physique, and the third was its powerful soul will.

In theory, the stronger the cultivation technique was, the faster it absorbed the spiritual energy. However, if the cultivator's meridians were too narrow and fragile, it would not be able to withstand the high intensity of spirit energy. The soul was also very important because during the process of cultivation, it required one to fully focus on circulating the cultivation technique and maintain 120% of one's spirit. Because during the cultivation process, if there was a slight mistake, it would result in qi deviation.

Ye Feng's physique was already strong, his meridians were also tough enough, and his soul and will were also strong. Adding the Creation Heavenly Scripture, he had the ability to absorb spirit energy at a fast speed for a long period of time.

The terrifying spiritual energy was like a surging river, flowing into Ye Feng's body continuously, and then being refined into the Profound Qi in his body.

About two hours later, Ye Feng felt the spiritual energy flowing out of the stone door gradually drying up.

"Crack crack!"

A large number of cracks appeared on the stone door. Finally, the cracks covered the entire stone door before it collapsed with a rumble.

"Hmm?"

Ye Feng woke up from his cultivation state and looked inside carefully. Below him, there was a vague and faint halo. This very weak white light allowed Ye Feng to clearly see what was within a dozen meters in an instant.

"Let's go in and take a look!"

After hesitating for a while, Ye Feng and the little thing entered the stone door from the hole and discovered a strange thing. Behind the stone door, Ye Feng actually could not feel any spiritual Qi of Heaven and Earth.

"This is really a ghost. Why didn't the spiritual Qi of Heaven and Earth come in?"

A big question mark was fixed on Ye Feng's head. With doubts in his heart, he slowly looked at the cave.

In the center of the cave, there was a stone statue. Carefully looking at the statue, he saw that it was carved from a huge bluestone. This was the statue of a woman, but this statue did not reveal anything. The carving skills were profound and the sword skills were skilled. Every slash was just right. It seemed to be done in one go from head to toe without any pause in the middle. The sharpness of the carving knife could be seen. The figure was vivid and lifelike.

"This carving technique is definitely much better than those bullshit grandmasters outside. This is definitely a priceless piece of art! Treasure has a price, art has no price! When there's a chance, I'll take it out for auction. I'll definitely make a huge profit! It's a pity that I can't take it away!"

When he thought of this, Ye Feng felt some regret in his heart.

"Yiya!" The little thing sniffed, then pointed to the right side and started drawing.

Ye Feng turned his head and saw that there were a total of twenty stone rooms. He didn't know which one was the first one, but he saw that they looked exactly the same. There was no mark on the door. Moreover, every stone room had a restriction placed on it, so his divine sense couldn't penetrate it at all.

"Which should I choose?" The little thing pointed at the stone doors and gestured with its two little claws at Ye Feng.

"Choose my ass. All of you, go in. One by one!" Ye Feng said straightforwardly.

"Yiya!" The little thing shook its head with all its strength, as if it wanted to make its mind clearer.

Time slowly passed. Ye Feng's mood gradually became lost along with the passage of time. Finally, there was only one stone room left. The first nineteen stone rooms were filled with rubbish. There was no treasure in the legends at all.

"Damn it! Since there's nothing here, don't close the door so tightly!" Ye Feng cursed.

Ye Feng, it seemed like this was the first time he had entered such a place. If there was no treasure, it would really make him feel depressed.

"God bless, I hope there are some treasures in this stone room, even if it's just a little bit, this trip will not be in vain! This is my last hope."

When Ye Feng opened the last stone room, he was in despair. There was no treasure inside. There was only a black hole. The first step of the stairs extended to the ground.

"Is the thing down there?" Ye Feng hesitated for a moment. In the end, he mustered up his courage. The Profound Qi covered his body, and his Star Martial Spirit was summoned. It surrounded his body, and he walked down the stairs one step at a time.

As he slowly went deeper into the cave, Ye Feng found that there seemed to be light coming from the end of the tunnel. He could not help but feel overjoyed, and he subconsciously quickened his pace. When he reached the end of the tunnel... The melancholy on his face was swept away. What replaced it was ecstasy.

"Hahaha... There is indeed treasure. Hahaha... Now I am rich!"

Ye Feng looked at the luminous pearls in the stone room and laughed crazily. In the stone room, there were shelves made of stone. Rows of jade slips were neatly placed on the shelves.

Ye Feng waved his hand and wiped away the dust on the jade slips. The glowing jade slip was revealed. Ye Feng felt a weak wave of spirit energy from the token.

He casually picked one up.

"Riiip! Riip!"

When Ye Feng picked up one of the jade slip, the rest of the jade slip actually emitted a white light and then turned into powder. Not only the jade slip, even the stone racks that held the jade slip also turned into powder.

"No!" Seeing so many jade slip turn into ashes in front of him, Ye Feng almost went crazy.

After a moment, Ye Feng had to accept this sad fact. He looked at the jade slip that was still intact in his hand and thought, "Fortunately, I still have one in my hand!"

He used his divine sense to scan inside, and a stream of information immediately flowed into his mind. Ye Feng digested the information bit by bit and slowly. Ye Feng's tightly knitted eyebrows gradually relaxed. It turned out that there were many ways to use a Martial Spirit in the jade slip.

"This jade slip, what era did it belong to?"

Ye Feng could not suppress the excitement in his heart. He sat there with his legs crossed and imprinted all the information in the jade slip into his mind. He did not dare to bring these things outside. If these things were to be known by those people... I'll take it at all costs.

However, in the last paragraph of this cultivation technique, Ye Feng was almost thrown into the ice valley. This was how the paragraph described - the secret technique was still in the midst of discussion. At the initial stage, it could be compatible with the natural source energy. At the later stage, it can even be fused with space and time. And thus achieve the final goal of the experiment...

"Damn, so it's an experimental cultivation method!" Ye Feng cursed the creator of this cultivation method in his heart.

However, seeing this, Ye Feng's mood also became a little better. "Maybe all the things recorded in the jade slip are experimental things, and their practical value is not high!"

Although this martial spirit secret technique seemed to be of little value, the creator of this secret technique... In the early stages, he had also referenced many of the top soul skill techniques from back then. Then, they merged together. This allowed the soul skill to be useful in the early stages.

At least, after looking at the jade slip, Ye Feng immediately felt that there were many ways to improve his Star Martial Spirit.

"Bang! Bang! Bang!"

Just as Ye Feng was lost in his thoughts, he was suddenly awakened by a series of noises. Looking at the source of the sound, he saw the little thing covering its throat and rolling around. It kept crying out in pain, looking like it was in extreme pain.

"Little thing, what happened to you?"

Ye Feng didn't dare to be neglectful. After being together for the past few days, Ye Feng had already regarded the little thing as his brother. Now that he saw the little thing in such pain, his heart ached.

"Yiya! The little thing stretched out its claw and pointed at its mouth with a painful expression.

"What is it?"

Ye Feng immediately opened the little thing's mouth and saw a red thin needle stuck in the little thing's throat. Ye Feng reached out his hand and pulled the red needle out of the little thing's throat.

"Serves you right. You eat everything you see. Now you know you're wrong!"

Ye Feng scolded the little thing with a cold face. The little thing looked like it had done something wrong. It stood there with its head down, looking at a jar at the corner of the wall.

Ye Feng did not pay attention to the little thing. He just looked at the thin red needle in his hand in a daze.

"This needle is so heavy!" The needle was completely red. It seemed to be emitting a strong fire element energy around it. The weight of the needle was almost one-tenth of the weight of the sword in his hand.
