His current combat power, the average low-grade martial emperor, would basically not be his opponent if he did not burn true energy. When he met a low-grade martial emperor like the old man in the blue robe who could use the ultimate yin fire to burn true energy, there would be some gaps.

If he could reach the realm of the Martial Emperor and refine his vitality into true energy, the old man in the blue robe would definitely not be able to walk ten moves in his hands, even if he burned the true energy, it would not work.

Compared with him, the blue-robed warrior has less martial arts skills than his in terms of true energy. If Xiao Chen uses the purple thunder true fire to burn the true energy, the blue-robed warrior may not be able to stop him from three moves.

A hint of eager gaze flashed in his eyes, Xiao Chen glanced around and said, "Stop talking about this, I can't wait to see where the source of the spiritual vein of Ao Jiao is."

"In the northeast direction, if you walk twenty miles, you should see a small hill with a restriction left by the Thunder Emperor. I'll help you open it."

Twenty miles were not too far away. Xiao Chen looked at him. Although he was eager to rush over, he was not really so reckless.

Sit cross-legged on the ground again, continue to heal the wounds, make sure there are no injuries, and rush over in the best condition.

Half an hour later, Xiao Chen opened his eyes again, his energy and energy were soaring, and his toes turned into a dragon and rushed away.

However, I didn't go far and encountered a little trouble. The dozen or so vicious fire spirits ahead were blocking their way. ~ Long~ Feng~ Literature                                                                                                                                                                                                                                            

A ball of purple thunder true fire popped out with his right hand, purple light flashed in his eyes, and a dazzling light suddenly appeared in the flames on his palm, but Xiao Chen also took out the heart of his origin.

The purple thunder true fire, which contains the heart of the origin, is completely incomparable to the previous one. Looking at the flying fire spirit, Xiao Chen shouted lightly and pointed at the object as a soldier!

The flames suddenly condensed and transformed, and eventually turned into ten sharp short swords. Xiao Chen waved his right hand and shot out with a whoosh.

Bang bang bang bang!

The purple fire short sword that was so strong that it was penetrated into the hearts of these fire spirits and immediately exploded. Ten difficult fire spirits were instantly blown into countless Mars.

Xiao Chen smiled slightly, purple light flashed in his right eye, and the short sword dissipated in the air turned into ten streams of light and escaped into his right eye again. With the short sword transformed by the purple thunder true fire, Xiao Chen swept across the way, and then arrived at the hill that Ao Jiao said for a quarter of an hour.

The hills are not big, less than two hundred meters high, three hundred meters in a row, and the soil is black. It looks extremely ordinary at first glance, and similar hills are endless in this underground world.

"The source of the spiritual vein is below?"

Xiao Chen walked around the hills and did not feel anything special about the spiritual energy here. No matter how you look at it, it was an ordinary hill.

Ao Jiao nodded and said, "Well, the source of this spiritual vein was not suppressed by the spirit gathering array. The spiritual energy has been leaking all year round. The Thunder Emperor took half of it back then. I was afraid that someone would appear here, so I just put out a ban, and wait for me."

call out!

After the words came to his voice, Ao Jiao flew out of the Yueying Sword, and the luster on the blade immediately became much dimmer.

It's been a long time since I saw Ao Jiao with my own eyes. Xiao Chen looked at him carefully and found that the other party had not changed at all. He was a head shorter than him, his appearance like a little girl, and his angered figure was still the same as before.

Looking at the hill in front of him, a look of nostalgia appeared in Ao Jiao's eyes, she sighed slowly, her hands began to quickly seal it, and finally pointed her small right hand forward and said in a pretty voice: "Open!"

The solid hills broke into two halves in Xiao Chen's surprised gaze, and a surge of spiritual energy surged out of it.

"Don't be stunned and go in quickly. Let the two people in the Holy Volcano Villa sense this spiritual energy, and the trouble will be great."

Xiao Chen understood this principle, and his body flashed, turned into purple light, and instantly entered the corridor at the foot of the hill. Ao Jiao then entered, and his hands formed seals again. The hill closed again with a loud bang, becoming extremely ordinary again.

The two old men in the blue robe who were moving towards the Netherworld Fire in the distance frowned at the same time. After being promoted to the Martial Emperor, the warriors began to cultivate their mental power and were extremely sensitive to the changes in the spiritual energy of heaven and earth.

In the moment just now, the two of them sensed an extremely powerful spiritual energy at the same time, and it suddenly surged out.

The old man in gray robe said, "Brother, do you want to go over and take a look?"

"Tianmiedhu was the former site of the imperial capital of the Tianwu Dynasty. Maybe a strange treasure appeared. I'll go over and take a look. Then you can deal with the Netherworld Fire Spirit later." The old man in the blue robe thought for a while and said.

The corridor is deep and dark, with thick spiritual mist all around it, and the walls are covered with dew made of liquefied spiritual energy, which looks like it has not dissipated for thousands of years.

There is no need to practice here. Just open your mouth and suck hard, and your cultivation can instantly increase, but Xiao Chen dared not suck.

There are also many impurities contained in the spiritual fog. The cave is not ventilated all year round. Those impurities cause considerable harm to the human body, so I can only sigh.

Walking forward, at the end, the spiritual mist dissipated, an underground river appeared in his eyes, flowing water rustled, and the fragrant spiritual energy came from above, and the entire river was actually transformed by spiritual liquid.

Xiao Chen sighed: "It's really not an ordinary waste. Let a spiritual river flow out continuously. Five thousand years have passed, how much spiritual energy will be consumed."

Ao Jiao, who came over, raised her mouth slightly and said, "I don't know, it's just a lowest spiritual vein. When you go to Kunlun Realm, you will know. When you see the ancient river of Tianquan, you will know what the real spiritual river is."

Xiao Chen couldn't refute the fact that he was despised by Ao Jiao, and he couldn't refute it even after a hint of his spiritual veins. He knew that there were levels of spiritual veins, but he didn't know how to divide them.

At the end of the Linghe River is the location of the source of the Spirit Veins. The two walked forward, Ao Jiao was on the way, and by the way, he talked about the division of the spiritual veins level with Xiao Chen.

Spiritual veins are divided into fifth-level, from low to high-level, first-level to fifth-level, first-level spiritual veins are the most common, and there will not even be any accompanying spirit stone ore around them. Only spiritual ore can exist around the second-level spiritual veins.

The Tiandao Pavilion has a second-level spiritual vein, but most of the spirit stones produced by the second-level spiritual vein are lower-level spirit stones, and there are few intermediate spirit stones to appear.

In turn, only the fourth-level spiritual veins produce large quantities of upper-level spirit stones, and the fourth-level spiritual veins are also called the top-level spiritual veins. There are less than five top-level spiritual veins on Tianwu Da 6, and they are in a state of depletion, so they can no longer produce large quantities of upper-level spiritual stones.

The fifth-level spiritual vein has been made into a holy-level spiritual vein, and there is not a single 6 Tianwu Great. Even in the Kunlun Realm, it is an extremely precious existence. As for the legendary king spirit vein, it is a phoenix-mao and horned existence in the Kunlun Realm, and only the king sect can master it.

While speaking, the two of them also walked to the end of the Linghe River. Xiao Chen looked at the source of the floating spiritual veins in the sky, and his eyebrows slightly frowned.

In the thick spiritual mist, the source of the spiritual vein was only the size of a palm.

In the spiritual fog, there was a little spiritual rain falling constantly, providing sufficient water for the spiritual river on the ground. In the center of the fog, there was a blue light ball floating quietly, and layer by layer was realized to spread out from the light ball.

Xiao Chen smiled bitterly and said, "I'm afraid I'm in vain this time. I remember the source of the spiritual veins of the Tiandao Pavilion, which gave me endless feelings, as if I were in the vast ocean."

However, Ao Jiao smiled happily and said, "Hehe, stupid master, you know everything if you pick up the treasure, you are even stupider than the wood master."

Xiao Chen said in confusion: "What do you say?"

"You can tell at a glance that you have never really seen the source of the spiritual vein in the Tiandao Pavilion. Even the source of the top spiritual vein is only three feet in size, so how can it be endless?"

After recalling it, Xiao Chen remembered that he really didn't. He really saw the source of the spiritual vein of the Tiandao Pavilion. At that time, he was just sitting on the cushion for a moment. The endless feeling was the scene in his mind.

Ao Jiao continued, "No matter how well the spiritual vein is maintained at the highest level, it will gradually weaken as time goes by. I guess the source of the spiritual vein of Tiandao Pavilion is only ten times the size of this spiritual source, and it will not be too large."

"You came just right. The spiritual source here is the limit that your body can bear at present. This reduces the risk of explosion."

Xiao Chen looked at the source of the spiritual vein with burning eyes, and became excited for no reason. He was promoted to the Emperor of Martial Arts to refine his vitality into true energy. Another door to the path of warriors was about to open to him soon.

Ao Jiao reached out to Xiao Chen for some top-grade spirit stones, and said calmly: "Although the risk has been reduced a lot, it is not without risks. Remember to say, don't be greedy, don't be blinded by power."

"When I set up the spirit sealing array, you can go and devour the spirit source. Remember what I said, don't forget."

Xiao Chen nodded and said, "You set up the formation."

With a wave of his right hand, a strong wind blew out for no reason, eliminating the thick spiritual mist. Only in the air could only see the beautiful and beautiful blue spiritual source floating quietly.

Whoosh!

After flying out of Ao Jiao's hands, he threw out one hundred and eight top-grade spirit stones, his hands began to change his hand techniques, and finally he gently tapped the spirit stones.

The spirit stone immediately showed a faint light, and lines shot out from above, linking all the spirit stones together. An extremely complex formation suddenly appeared above the spiritual source.

The eighteen corners of the formation each shone a brilliant light, blocking a world inside.

Ao Jiao said softly: "The spirit sealing array has been laid out, and the spiritual energy in the spiritual source will no longer be released, you go."

Success and failure are here, Xiao Chen took a deep breath and floated gently, and flew to the center of the formation's eyes and sat cross-legged. The spirit sealing array formed an invisible plane in the void, and Xiao Chen could float it without standing.

The first-level spiritual source, the size of a palm, was floating quietly above Xiao Chen's head.

boom!

The moment he sat down, a surging river appeared in Xiao Chen's mind, and the rivers were surging, as if they could destroy all the embankments in the world and sweep the world.
Chapter completed!
