The cave was very deep, and they walked for a long time, and the more they got below, the aura gradually became stronger. This place used to be a spiritual stone vein, and although it has been abandoned, the aura here is still stronger than the outside world.

The bottom of the cave gradually opened up, and occasionally some scattered spirit stones could be seen, and when they reached the bottom completely, the top of the cave was already ten zhang above the ground.

"There's nothing special here!" Luo Hao looked at it for a long time, but he didn't find any treasures.

This place looks like an ordinary spirit stone vein, but it has been mined, and everyone began to search around. As the two guards at the entrance of the cave had said, if it was so easy to find, it would have been taken before.

"Huh?" Lin Feng's heart moved, and he felt a breath, which was similar to the essence and blood of the Dragon Emperor in his dantian.

Following this breath, Lin Feng came to a shadow of the cave, where there was a boulder, and when he moved the stone slightly, Lin Feng found that there was a deep pit exactly the size of a person below.

"This must be their discovery, there must be something good down there. Seeing Lin Feng moving stones, Luo Hao stepped forward.

Several people glanced at each other, nodded and then got in, they all came, how could there be no reason not to go down and take a look. Because they were afraid that the pit would be too deep and that they couldn't fly, they had to support both sides of the cave with their arms and slowly move down.

Lin Feng was the last to go down, and after entering the pit, he moved the stone back to its original place. The pit went straight down, and after two quarters of an hour, the people fell out of the pit and landed on top of a big tree.

"How can there be trees underground?" Luo Hao wondered.

"It's an underground world. Zhang Hao looked around and said.

Lin Feng stood on the top of the tree and looked into the distance, this was a vast space, it was the underground world. There is no sunlight here, but many of the plants emit light, making it not look dark.

There are mountains, flowing water, forests, vegetation, and many animals, but they are all small creatures.

"Where exactly is the Ten Thousand Insect Country adjacent to our Burning Cloud Country?" Just as a few people were looking around curiously, Lin Feng suddenly asked.

"It's not far from the Lieyun Sect, what's wrong?" Zhang Hao replied directly, and was puzzled, I don't know why Lin Feng is asking this.

"That's right......" Lin Feng nodded, and when he entered here, his feeling of dragon qi became even stronger, and he felt that this place was somewhat similar to Juelong Ridge.

This is a dragon vein, so dragon qi will be born, thousands of years ago, the Tianhan Sect set the sect here, and it should also be aware of the dragon vein.

However, there is a huge problem with this dragon vein, that is, it has encountered the Absolute Dragon Ridge, which isolates the general trend of heaven and earth, and directly cuts off the dragon vein, making it turn into a dead dragon.

This place is a dragon vein that has been cut off, and after tens of millions of years of evolution, dragon qi has also been born. If nothing else, this place will become a dragon vein of its own in the future.

However, due to the suppression of the Absolute Dragon Ridge, it can only be a small dragon vein, and it cannot become a climate.

"Dragon Qi!" Zhang Hao was shocked, the dragon energy can also be called the luck of the dragon vein, he naturally knows this thing, as a prince, he is very yearning for this thing.

Once he has dragon qi on his body, his luck will change dramatically, and often only the true son of heaven has a trace of dragon qi on his body, if he can have it, it will be of great benefit to him to compete for the throne in the future.

Zhang Hao immediately closed his eyes and sat cross-legged, running the imperial exercises, and sure enough, he sensed a faint trace of dragon qi, which surprised him. At the same time, he also glanced at Lin Feng in surprise.

His royal martial arts had a special sense of dragon qi, but even so, he only had a faint feeling, but Lin Feng seemed to have already sensed the existence of dragon qi.

Following the induction, several people came to the side of a river that was dozens of zhang wide, the river was meandering, the water was turbulent, like a galloping dragon, and there were four small tributaries beside it, very much like dragon claws.

A few people went uphill along the river, and the dragon head above was the place where the dragon qi condensed. The river was long, but the speed of the crowd was also very fast, and soon they saw a waterfall hanging in front of them, and the sound of the water rumbled and the green smoke curled.

"This is it. ”

Everyone stopped, the waterfall was very high, like a dragon gate, jumping up, it was the sublimation of life. They looked surprised, the dragon vein, which has always existed in legends, is too difficult to see.

Even if there is, it will be quickly occupied by some super powers, which will let them watch it so closely.

"The dragon qi is inside the waterfall. Lin Feng's sense of dragon qi became stronger and stronger.

Moreover, as Lin Feng approached, the dragon qi seemed to be active as well, which was a joy to feel like the same kind.

"There are corpses here, there has been a battle here, could it be that someone has already taken the lead?" Song Hang suddenly exclaimed.

Lin Feng turned his head to look, he had been paying attention to the dragon qi just now, but he had ignored the surrounding scene. Everyone immediately raised their vigilance, because of the dragon qi, everyone was more or less relaxed just now.

But at this moment, they suddenly realized that this was not the Burning Cloud Country, but in the territory of the Ten Thousand Insect Country, once they were discovered, they would definitely be intercepted and killed, although the identity of several people in the Burning Cloud Country was not ordinary, but here, the Ten Thousand Insect Country could have no scruples.

Lin Feng walked to the side of the corpse, there were five in total, and after looking at it, Lin Feng found that it had only died in the past two days, the wounds were not deep, but they were all fatal with one blow.

"The deaths of these men were more or less the same, they were all relatively peaceful, and none of them seemed to resist. And the expressions on their faces were all dazed or surprised, it seems that they were attacked by a sneak attack, and they were killed by a sneak attack by someone they trusted. ”

According to the death of the corpse, Lin Feng analyzed it, and then, he guessed: "It should be that they discovered this place, but they were killed." ”

"It should be like this, after all, this is dragon energy, and it is not allowed to be sloppy, and the people of the Ten Thousand Insects Country had to kill all the insiders in order to prevent the news from leaking out. Zhang Hao also nodded, this kind of behavior is not uncommon in the monk world, it is not surprising.

"Let's go behind the waterfall and take a look, the heavy troops of the Ten Thousand Insect Country have not yet arrived, and even if there are people here, it should not be too strong. The crowd continued to move forward.

There is a cave at the back of the waterfall, which is where the dragon's head is located and where the dragon's energy is born. They cast the Heavenly Cold Transformation Technique, condensed the water balloon outside their bodies, and then carefully entered the cave.

"Huh?" everyone was shocked, there was nothing inside the cave, no enemies in ambush, and no dragon energy existed.

"Has it been taken away?" asked Song Hang. He didn't have the technique to sense dragon qi, so he didn't know if dragon qi still existed.

Lin Feng urged the aura in the dantian, and used the aura to shake the dragon emperor's essence and blood, he could feel that the dragon qi was in the cave, but this kind of thing was born psychic and knew to hide himself.

The essence blood was as steady as a rock, in the center of the dantian, motionless, and it took Lin Feng a lot of effort to make it tremble.

In an instant, as if sensing a strange movement, the breath in the cave began to surge, and then, a white gas appeared in front of everyone's eyes, like a small snake composed of mist.

It wandered around the cave, then circled around Lin Feng twice, and Lin Feng tried to grab it, but as soon as he reached over it, the mist dissipated, and then regrouped not far away.

"Let's try to see if you can absorb it!" Lin Feng said to Zhang Hao.

This dragon qi has a huge effect on Zhang Hao, but it is of little use to him, he has the essence blood of the Dragon Emperor, so he naturally doesn't care about such a small cloud of gas.

Zhang Hao looked surprised, he didn't know how Lin Feng did it, he was able to make the hidden dragon qi active.

But now was not the time to think about this kind of question, he hurriedly sat cross-legged, ran the exercises, and began to pull the dragon qi into his body.

The dragon qi does not have spiritual sense, but it has instinct, and it is very resistant to Zhang Hao's traction. And Zhang Hao is not in a hurry, he knows that this kind of thing cannot be done overnight, and he needs to take his time.

Lin Feng and the three of them sat cross-legged, Song Hang and Luo Hao didn't have the method to pull dragon qi because of the exercises, so naturally they didn't have anything to do now.

In the blink of an eye, seven days have passed, this time this place is very quiet, no one has come, Lin Feng and the others can just take this opportunity to comprehend the Heavenly Cold Transformation Holy Recipe again.

Although they have already comprehended, three days is too tight, and they can only get started. After careful study, Lin Feng found that this method did have outstanding points, and the value alone was definitely much higher than that of Fengxing Nine Steps.

In fact, if you think about it, you can understand how powerful the Tianhan Sect was at the beginning, and their core method was naturally very good. And when the Tianhan Sect perished, his ancestor Lin Jiuxiao was only one of the more outstanding members of the coalition army.

Lin Jiuxiao's exercises and secret techniques naturally could not be compared with a huge sect that had been passed down for thousands of years. But the nine steps of Fengxing are not useless, at least in terms of speed, this technique is still very strong.
