The reason why the warriors of Loulan can refine the Dragon chakra is that there is an unknown force changing the chakra in their body because of the terrain where their country lives.

At the beginning, the chakra they extracted was also ordinary, but with the passage of time, their physique was changed, so the refined chakra was transformed into dragon chakra.

After discovering this problem, the queen of Loulan naturally looked for the problem. Then she found that there was something similar to the altar at the bottom of the castle, and a wellhead in the center of the altar was the source of unknown power.

Because this unknown force did not bring casualties to Lou Lai, but also enhanced the strength of Roland warriors, the queen did not do anything about it, but sent heavy troops to guard it.

It's a pity that if one knows such a secret thing, it's OK. With more and more people knowing it, the news spreads faster and faster, so that it is involved in the war because of the relationship of dragon veins.

During the war, every country, big or small, had only one purpose, that is, to expand its territory and enhance the strength of its own country. After the news of Loulan dragon vein was spread to the outside world, it attracted the peep of many tolerance villages, including shayin village, one of the five tolerance villages.

Although the warriors of Loulan had the dragon vein chakra, they were still defeated by ninja. Finally, the ancient country of Loulan disappeared at the beginning and end of the Third World War. Finally, although the dragon vein was discovered by the people of shayin village, it could not be transferred.

They didn't even know what the dragon vein was, so there was no treasure mountain to use. They could only leave some ninjas of shayin village to refine chakra here, so that the strength of shayin village suddenly increased a lot in the middle of the Third World War.

Other tolerant villages are not idiots. After seeing the improvement of the strength of shayin village, they will not let go of the dragon vein, but the dragon vein is too far away from their village and has no advantage of shayin village.

Fortunately, the dragon vein was finally sealed by the golden flash of wood leaves and the wave wind water gate. It was still sealed by the powerful seal of the vortex family. So far, the existence of the dragon vein has been gradually forgotten by outsiders.

"It should be around here." Xiaozhi came to a place in the desert. Looking at the endless sand, Xiaozhi felt a strange force attracting the blood in his body.

"Ding ~!"

"Find unknown power underground at a distance of 700 fans from the host."

"Seven hundred fans?"

"It should be the dragon vein." The sudden system prompt sound startled Xiaozhi. Now, except when necessary, unless he calls the system actively, the system will not come out voluntarily.

Looking at the virtual screen map that only you can see, Xiaozhi follows the red punctuation. When the distance is getting closer and closer, the blood in Xiaozhi begins to flow rapidly in the body, and the four infinite gemstones in the soul also begin to rotate irregularly.

"It's hard to say." Thinking of some possibility, Xiao Zhi became excited and began to sneak into the ground. After living in five attributes, Xiao Zhi exchanged for the complete collection of ninja. It can be said that no one is more skilled than him.

"Click."

"Bang!"

More than 2300 meters underground, Xiaozhi fell from the soil to a dark place, which is also the center of unknown energy on the ground.

"Ding ~!"

"When you find an energy gem, the holder can have a super energy recovery speed, which can almost reach infinity!"

"Sure enough, I didn't expect to find it here." After hearing the prompt sound of the system, Xiao Zhi almost shouted with excitement. Although there was no divine gem, even if other gemstones were fused by him, they could not play their original power. However, from the weakening of the infinite power of the power gem to only a few times, the energy gem would not be weakened too much.

"Write wheel eye." Holding back his excitement, Xiao Zhi opened the writing wheel eye and kept approaching the energy gem.

"Hahaha, I found it." Seeing the gem wrapped by red energy in front of her, Xiaozhi couldn't help laughing, and then couldn't wait to integrate the energy gem into her body.

"Boom!!!"

"This... This recovery speed." After integrating the energy gem, Xiaozhi immediately felt that chakra in his body was recovering three or four times faster than before. You know, Xiaozhi has lived in the blood of thousands of hands, and the recovery is fast enough. It's terrible to think about it three or four times.

"I'm afraid Loulan's warriors are affected by the power emitted by the energy gem, but they never thought it would be a gem."

After returning to the ground again, Xiao Zhi really didn't expect that this time would be so smooth. It was completed in less than three hours since he left Yuyin village, which made him feel unrealistic.

"Huodun · Haohuo extinguishes." Facing the empty desert, Xiao Zhi made a seal with his hands, took a deep breath of air, and then ejected a flame within 40 or 50 meters.

"Boom." In the already hot desert, the flame has increased. The sand in the distance is blackened by Xiaozhi's fire.

"It's worthy of being an energy gem. Even if I can't get infinite energy because of the relationship between the throne gem, I think even huiyeji can't match me in this kind of resilience."

Feeling chakra's instant recovery in the body, Xiaozhi unknowingly smiled. The Haohuo extinction is comparable to the S-level Huodun ninja. The consumed chakra should not be underestimated, but it recovered in an instant, which shows the horror of energy gemstones.

"Huh?" At this time, Xiaozhi suddenly found that there was a trident on the ground just where he was. It was just covered by sand so that he didn't notice it just now. It came out after being swept away by the fire···
