"Rumor has it that the entire Earth Sky Continent is connected together by numerous veins of the Earth. The veins of the earth are the blood vessels and meridians in the Earth Sky Continent. "

"The veins of the Earth are divided into four categories, from highest to lowest: Sky Dragon Earth Vein, Earth Dragon Earth Vein, Profound Dragon Earth Vein, and Huang Long Di Mai."

While Tiemu Fenghuang was introducing them, she said enviously, "Your Hidden Dragon Academy sure is extravagant, to actually have them open at will!"

"You know, in my entire Tiemu Family, I only have one Huang Long Di Mai and it's even in the Ancestor's hands. I can only soak in it two or three times a year at most."

"This must be the treasure of the Tiemu Family!"

Inside the window, the deacon clearly recognized Tiemu Fenghuang, but he didn't ask why she was here. Instead, he explained, "Not only has my Hidden Dragon Academy been opened to the outside world by the Huang Long Di Mai, there is even the profound dragon's vein … However, if you want to soak in it, you will have to complete the mission and use your credits to exchange for it. "

"The reason why Cheng Feng is free this time is to reward him for completing the dangerous level mission for the first time."

"If he wants to soak in Huang Long Di Mai again, he will have to pay one hundred credits a day."

100 credits.

It didn't sound like much.

But you have to know, Cheng Feng only received a mere one hundred and eighty credits for expelling the mutated Giant Sword Shark.

And for this mission, if it were any other person, even if it was High Rank Heavenly Martial Stage, or even the Peak Heavenly Martial Stage Martial Cultivator, they would probably not be able to return.

From this, it could be seen just how valuable the three days and three nights of soaking in the Huang Long Di Mai were.

No wonder even the great young miss of Tiemu Family was envious!

"Excuse me, where is the Huang Long Di Mai?" Cheng Feng's eyes lit up.

One of his two biggest weaknesses was his low cultivation level.

If he could borrow the Huang Long Di Mai s' power to break through to the Heavenly Martial Stage in one go, then his chance of fighting Tiemu Dengke in the future would be much greater!

"In our academy, there are a total of a few hundred Huang Long Di Mai. They are all located on the ninety-seventh peak."

The deacon introduced, "Wait a moment, take your school card and go to the 97th Peak. After you pass the verification, you will be allowed to enter."

"Thank you for your guidance, senior." Cheng Feng thanked him.

Most of the deacons handling business here were from the older generation, so it was reasonable for Cheng Feng to call them seniors.

After the mission was completed, Cheng Feng immediately rushed to the Ninety-seventh Peak of the Book Mountains with Tiemu Fenghuang in tow.

This mountain of books was like a book that had been flipped open. The pages of each book formed numerous mountain peaks.

Cheng Feng quickly arrived at the top of the mountain. It was very quiet here, and there were less people.

However, the security was extremely tight.

Not long after Cheng Feng arrived, a 50-60 year old old man with long hair and a crown on his head suddenly walked out.

"Hello, I'm the student of Knife Tower Peak, Cheng Feng …" Cheng Feng took a few steps forward, handed over his credit card, and introduced himself.

"I understand, you can enter the Huang Long Di Mai to soak for three days. Follow me."

The long-haired, crowned elder returned the credits back to Cheng Feng, then brought Cheng Feng into a natural cave. Afterwards, they went all the way down, and continuously delved deeper.

Inside the cave, fist-sized Night Pearls were embedded every seven to eight meters, brightening up the path.

Cheng Feng and the rest walked down for about four to five thousand meters before a surging wave rose.

These waves of air were completely condensed from pure origin energy.

However, it was even purer than the Essence of a Superior Grade Element Stone or even a Highest Grade Element Stone. It was mixed with a kind of spirituality that made one feel refreshed after taking a breath, causing their entire body to soften.

Not long after, many Stone Chamber s appeared in front of them.

Some of these Stone Chamber s had their doors closed, while some of them had their doors opened wide. The wave of air that had been rising earlier, had rushed out from within these Stone Chamber s.

"The Stone Chamber of the Huang Long Di Mai is right in front of us. The door is open, which means there's no one inside. You can choose one and train inside at will."

The old man pointed to the sets of Stone Chamber and said: "As for you, little girl, you are not allowed to enter. Come with me and leave this place later."

"Senior, please wait for a moment." With that, Cheng Feng arrived in front of Tiemu Fenghuang and counted on her body.

"Cheng Feng, what are you doing?" Tiemu Fenghuang shouted in anger.

"I'm trying to save you."

Cheng Feng smiled and said, "I have set up a ninety-nine Heavenly Saber Formation in your body. If I do not temporarily stop it, once you leave, the only road left for you is death."

"However, don't think that you can sneak out while I'm soaking in the Huang Long Di Mai …" Because I only temporarily slowed down the operation of the ninety-nine Heavenly Saber Formation. It can allow you to move about ten kilometers away from me. "

"If you exceed this distance, the formation will immediately activate and kill you."

After saying that, Cheng Feng nodded at the old man, picked a Stone Chamber, and entered.

"Ninety-nine Heaven Saber Formation?"

Outside Stone Chamber, after the old man heard Cheng Feng's words, his eyes lit up: "This formation seems to be extremely exquisite, but I have never heard of it before … Little girl, follow me. Maybe I can help you unravel this so-called Heavenly Saber Array. "

Inside the Stone Chamber, the moment Cheng Feng entered, he was immediately tensed up by the abundant energy.

So it turned out that this room's Stone Chamber was the rock stratum that completely surrounded the Huang Long Di Mai. Cheng Feng entering the Stone Chamber was equivalent to entering the Huang Long Di Mai s.

As for Huang Long Di Mai, it was the entire Earth Sky Continent's meridian and blood vessel. The surging vitality within it was equivalent to the blood of the Earth Sky Continent.

One could imagine how pure it was.

"Damn, the Essence in this place is simply like a wild horse that has broken free of its reins. If my body is not strong enough and my meridians are not strong enough, I'm afraid I will die from the impact."

Within the Stone Chamber, after the stone door closed, Cheng Feng immediately felt what made the Huang Long Di Mai special.

He discovered that every strand of origin energy here was like an origin energy flood dragon, savage and tyrannical.

When it rushed into Cheng Feng's body without restraint, it wantonly rampaged about, silently hammering and tempering Cheng Feng's body, meridians, skin and flesh … This allowed Cheng Feng's every inch of skin to receive training.

Of course, this process was not easy.

If Cheng Feng's body was not strong enough and his willpower was not strong enough, he would completely collapse and flee in less than half an hour.

Bang bang bang bang …

Under the violent impact of the Essence Qi, Cheng Feng's body was pressed tightly against the stone door. Although the Essence Dragon had entered his body and ravaged all the meridians in his body, Cheng Feng did not feel any pain at all.

He actually let out an excited scream.

"Great, this is great!"

Cheng Feng shouted excitedly, because he realized that, in just a few minutes after he had entered the Stone Chamber, the thirty-third River of Essence had been born from his body.

Moreover, this was only the beginning …

Just as Cheng Feng was soaking in the Huang Long Di Mai, in a small courtyard on the ninety-seventh peak of the Book Mountains, the old man who brought Cheng Feng in was silently staring at Tiemu Fenghuang in a daze.

"Mr Mirror, are you able to deactivate that ninety-nine Heavenly Blade Array set up by that bastard Cheng Feng?"

Tiemu Fenghuang said to the old man with the long hair. "You have been researching it for quite a few hours."

"Little girl, breaking this formation is a delicate task, you can't be too hasty."

The old man called Mr Mirror said calmly, "The formation in your body is very exquisite. If you make a mistake, it will be beyond redemption and you cannot be careless. This old man needs to think it over carefully. "

After saying that, Mr Mirror was once again stunned.

However, in reality, his mind was working rapidly, deducing the principles behind the ninety-nine Heavenly Saber Formation's framework as well as the method to break it.
