Sun Zhengyang's state at this time was not good.

He was imprisoned in the Blackwater dungeon for eight years, and had to endure all kinds of inhuman torture every day, including whipping, iron burning, and torture instruments...... , there are all kinds of scars all over his body, and his cultivation is almost completely wasted.

At this time, above the dungeon, there were various rumbling noises from time to time.

It can be imagined that at this moment, the battle between Lei Guangpeng Bird and Lord Yuan was so fierce.

"Dad, I'll carry you away. Saying that, Sun Chengcheng wanted to act.

At this moment, a black-clothed guard came to inspect and found the beautiful Xiaozhi who fell asleep on the ground, and then saw Sun Cheng, who had revealed his true face at this time, where did he not know that something had happened?

Immediately, he asked, "Who are you?"

Where would Sun Cheng reply to him? As soon as he moved, the true yuan in his body frantically poured into the demon slayer knife, and he used the first form of the Great Sun Sword Technique, and slashed towards the black-clothed guard with one sword.

This black-clothed guard has the fourfold cultivation of the Yuan Martial Realm, and his strength is even higher than Sun Cheng's, but he never thought that Sun Cheng would not say a word, and directly burst into a surprise attack, and he didn't react in a hurry, so he could only deal with it in a hurry.

Although the black-clothed guard rolled on the spot and avoided the vital points of his body in time, he was still chopped off by Sun Cheng's arm.

Seeing that his left arm was cut off, the black-clothed guard's eyes were red, and he burst out: "Boy, I want you to die." Then he directly went crazy and Sun Cheng attacked and killed him.

Although the black-clothed guard was originally one level higher in strength, he was missing an arm and was seriously injured, and his strength could only exert five layers at most.

In this way, Sun Cheng is not in a hurry. The black-clothed guard was seriously injured, and he would definitely not last long.

Sure enough, only about five minutes passed, because of the fierce fighting, the black-clothed guards didn't have time to deal with the wounds at all, so that the blood sprayed wildly, and their strength became more and more weak.

In the end, he was slashed by Sun Cheng and slashed directly on the center of the zenith eyebrows.

The entire black-clothed guard was split in half on the spot, and his death was extremely miserable.

Black-clad guard, killed in battle.

Sun Cheng killed the opponent, panting and slumped on the ground, he was also afraid in his heart, the opponent just now was too strong, it was definitely a fluke that he could win, if the other party insisted for a while, he was the one who was very likely to die.

After meditating and pranayama for a while, after recovering the true element in his body, Sun Cheng stood up again, and was about to pick up his father Sun Zhengyang and rush out of the dungeon.

At this time, Sun Zhengyang stopped him and said: "I see the excitement outside, and I can't finish it for a while." I have something to tell you. ”

"Huh?" Sun Cheng was stunned, how could he delay at such a dangerous moment?

"Cheng'er, don't you think it's strange that this secret room dungeon actually has a dragon pattern magic circle?

Sun Cheng understood, it was true. Although my father used to be a master of the Nine Layers of the Yuan Martial Realm, now that he is no longer cultivating, there is basically no threat, and there must be other reasons for being so secretive.

Sun Zhengyang smiled and said, "You walk to the stone wall on the right side of this secret room dungeon by yourself, and you will understand." ”

Sun Cheng was stunned for a moment, and then looked at the stone wall intently.

I saw that on the stone wall, there was a faint carving of a coiled dragon, which was particularly vivid and vivid.

Sun Cheng walked to the front of the coiling dragon carving and found that the carving was completely natural, and there was no trace of artificial carving.

Then, Sun Cheng walked to the stone wall, and pointed out a trace of true yuan with his fingertips, and pointed it at the place where the dragon head was engraved with the dragon pattern.

Suddenly, the entire coiling dragon seemed to come to life, turning into a red dragon of light, circling in the air for two or three minutes before it dissipated.

"In the depths of this blackwater dungeon, there is a dragon vein hidden. Sun Cheng was taken aback, and his face could no longer help but show ecstasy. With the insight of Emperor Wu in his previous life, he was naturally sure that there would be no mistakes.

In the Longwu Continent, there are dragon veins that travel to all parts of the world, condensing aura for the world.

There are 3,000 dragon veins in the world, divided into nine true dragon veins, eighty-one heavenly dragon veins, and the remaining 2,910 are earth dragon veins. The one in front of him, if Sun Cheng is not mistaken, should be one of the earth dragon veins, the True Flame Earth Dragon.

Sun Zhengyang, who was on the side, was also surprised that Sun Cheng was able to recognize the dragon vein, but in the end, he was a character who had experienced too much wind and rain, so he didn't dwell too much on this, and then said: "This place was originally a trapped dragon situation, and the ghostly stagnant water in the black water lake was attracted by a peerless powerhouse, trapping this true flame earth dragon in this small island in the middle of the lake, constantly consuming its power. ”

Sun Cheng nodded and came back to his senses. It's no wonder that Qingyang Town, such an inconspicuous town, can have such a magical place as Heishui Lake.

The so-called dragon sees the head but does not see the tail, the dragon veins in the world have spirits, and they travel all over the world, and in ordinary times, they can't be found at all. That is, I occasionally heard that when a child was born, he was contaminated by the dragon vein, and a dragon spirit was born in his body, and he could have the potential to become a dragon pattern master.

Sun Zhengyang continued: "When the Li family ancestor came up, he accidentally found that there was a trapped dragon here, so they set up this black water dungeon on the island in the middle of the lake. All kinds of powerful demon beasts and warriors are imprisoned here, just to use their essence and blood will to wear down the spirit of the dragon vein. When this dragon vein returns to the chaos and is first born, it will be enslaved by their Li family and driven by it. ”

Hearing Sun Zhengyang say this, Sun Cheng also understood, and said: "So my father, as a strong person in the Nine Cultivation of the Yuanwu Realm, although the cultivation is not there, the essence and blood in the body are strong, and the purpose of imprisoning you with the True Yan Dragon Vein is to use your essence and blood to suppress the Dragon Vein every day." ”

What a cruel torture it was to think of my father being imprisoned here for eight years, not to mention the day, and to endure being bled every day!

At this moment, Sun Cheng's face showed a raging anger, which was simply monstrous hatred.

"Dad, we and the Li family have long been at odds with each other, and one day, I must let their Li family cut off their children and grandchildren, and they will be wiped out. ”

Sun Zhengyang waved his hand and said: "Cheng'er, let's not talk about these things first, you first go to the edge of this dragon vein stone wall, practice exercises, and see if you can let the true yuan in your body be contaminated with a trace of dragon vein qi, so that the condensed true yuan is enough for you to save years of hard work." ”

Sun Cheng smiled and nodded in agreement, and sat down cross-legged on the side of the dragon vein stone wall.

However, he didn't simply want to be contaminated with some dragon vein qi, but he had a greater ambition to directly refine and absorb this True Flame dragon vein and become a part of his body.

He cultivated the "Ancient Dragon Divine Technique", and he had long been hungry and thirsty for this dragon vein.
