"Absorb the crystals of the wind insects and comprehend the wind system vitality technique to return to the wind. ”

"Isn't it the Boundary Wind?" Zhou Wen was slightly disappointed, he had already seen the strength of the Boundary Wind, and he was originally full of expectations that it would be the Boundary Wind, but who knew that it was not.

After carefully looking at the information of the return wind, I saw that the return wind turned out to be a passive vitality technique of the wind system, which could not be used actively, and could only be used if certain conditions were met.

Return Wind: Requires a Knife Qi Elemental Skill to trigger to produce a Return Wind effect.

Zhou Wen didn't know what the return effect meant, but he knew a kind of sword qi type Yuan Qi technique, that is, the Star Cutting Knife that exploded from the mutation demonization general, but later the Star Cutting Knife was merged into a magic star wheel by Zhou Wen's three skills, and now Zhou Wen didn't know if it was a sword qi type Yuan Qi skill.

"Now that you've learned, let's give it a try. Zhou Wen continued to walk forward, and when he arrived at the hiding place of a wind insect, while drawing the knife, he used the Demon Star Wheel Yuan Qi technique, only to see a round of blood light slashing out from the bamboo knife, forming a round of blood light, like the saw blade of a cutting machine, directly cutting the stone pillar in half, and the wind world insect in it was also killed together.

Zhou Wen put the knife back into its sheath, and was about to walk over to check the corpse of the Wind Realm Insect to see if there were any crystals in it, but he saw a flash of blood, and the Wheel Star Wheel that Zhou Wen had cut out before actually flew back upside down, but fortunately, Zhou Wen reacted quickly enough to dodge it, otherwise he would be slashed by his own Yuan Qi Technique.

Click!

The Demon Star Wheel slashed at the stone wall behind Zhou Wen, splitting the stone wall in half, and the Demon Star Wheel disappeared.

"What kind of wind is this, it's kind of interesting. Zhou Wen was slightly surprised, after the ordinary Yuan Qi technique was cut out, it was uncontrollable.

However, the return wind skill made it possible for the Demon Star Wheel to be manipulated.

"Young Master Wen's sword qi is so weird, it seems to have some similarities with the legendary whirling sword qi, but it is not the same, the whirling sword qi wins with skill, and the sword qi arcs, which is difficult to figure out, but the destructive power is insufficient. Young Master Wen, your sword qi is domineering but extremely weird, making people unguardable, if I hadn't seen this knife, I would never have imagined that the knife qi would be able to return, and there would be a chance that the ** would be hit hard, and it might even be killed. Lu Yun said first.

"I haven't been learning for a long time, and I haven't been able to master it yet, which makes you laugh. Zhou Wen said.

"Then you really have to practice it well, such moves often have miraculous effects on the battlefield. Lu Yunxian said seriously: "Battlefield fighting, the emphasis is on killing with one blow, everyone is fighting with all their might, but suddenly a knife comes from behind, I'm afraid few people can dodge." ”

"Good. Zhou Wen nodded: "Let's talk about it later, it's important to find An Sheng and them now." ”

Zhou Wen is quite familiar with the inside of the ruins, and he deliberately detoured some roads in order to kill the Wind Realm Worm before, but now the Wind Crystals he wants have been obtained, and the Wind Realm Worm Crystals have also been absorbed, and he will no longer detour at the moment, heading towards the entrance of the underground passage.

"Young Master Wen, could it be Liu Chengzhi there...... No...... Mei said that the underground entrance ......," Lu Yunxian said, pointing to a dilapidated building.

The building was boxy like a stone box, except for one side, from which a stone staircase could be seen leading underground.

On both sides of the stone steps, you can also see two strange stone statues, one on the left is like a tiger but has wings on its back, and the one on the right is shaped like a bird, but on the top of its head has two horns like a bull.

"This should be it. Of course, Zhou Wen knew that this was the entrance to the underground passage, and in the game, he had been here many times, but he had never entered it.

Not seeing An Sheng and them here made Zhou Wen, who had expected it a long time ago, slightly disappointed, so he could only enter the passage to find them.

"I don't know if this thing can replace the role of stone tools?" Zhou Wen glanced at the stone eggs in the chaotic space, and his heart was slightly depressed.

"Young Master Wen, I'll go and explore first. Lu Yun said first.

"Don't go in yet, there are many dangers here, it doesn't matter if we get stuck in it, if we lose the stone tools, it will be worth the loss. Zhou Wen said.

"Then what should we do?" Lu Yun asked first.

"Let's wait for a day or two, and if Ansheng hasn't come out by then, we'll go in. "Zhou Wen needs time to understand the situation in the underground passage, otherwise he will be sent to death if he goes down.

After all, he is still only a legendary, and his own cultivation is not strong enough, and he can't forcibly break in like An Sheng and Ouyang Lan, in case of an accident, his own strength is insufficient, and he is likely to not be able to cope with emergencies.

Lu Yunxian is now looking at Zhou Wen's head, and since Zhou Wen said so, he has no opinion.

"You stay here, and when they come out, I'll clean up all the bugs in the ruins, so that they don't get into trouble when they come out." Zhou Wen said and was about to leave, but suddenly heard a strange sound coming from the underground passage.

Zhou Wen listened attentively, the sound was a bit like the sound of a train moving on the tracks, clanging...... Bang Bang ...... It was very regular, as if there was a real train running underground, and the sound was getting louder and louder, looking at the black stone steps, it seemed as if a train would rush out of it at any moment.

"It's a pity that Diting is evolving, otherwise with its ability, it can hear what's going on inside. "Zhou Wen has now begun to miss the ability to listen, that ability is too many aspects, and it can solve many problems.

"If I'm not mistaken, there was no railway passing through here before, so there shouldn't be a train, is there something similar to a train in myths and legends?" Lu Yun listened to it for a while, and also felt that the sound was like a train.

Zhou Wen shook his head and said nothing, in this era, he would not find it hard to believe that a spaceship came out of the ground.

The two of them stared vigilantly at the stone steps, which were pitch black, like the huge maws of hell monsters, and they couldn't see anything, but they only heard the clattering sound getting louder and louder, as if a train was really about to come out.

Zhou Wen and Lu Yun glanced at each other first, and both of them stepped back to one side, each standing on either side of the stone staircase passage, in case there was really a train rushing out inside, it would not directly hit them.

As the sound got closer and closer, Zhou Wen felt that there was really a train about to rush out, and in the darkness, Zhou Wen seemed to see the lights of a locomotive flickering.

"Is there really a train down there?" Lu Yunxian also saw the light and couldn't help but say in surprise.

"I don't know if it's a train or not, but it's coming out, be careful. Zhou Wen summoned the Dark Physician and asked him to attach himself in a soul state, and then used the Dark Physician's Perspective Light skill to look towards the dark passage.
