"Absorb the crystals of wind-facing insects and understand the wind-based energy technology return to the wind."

"Isn't it a world wind?" Zhou Wen was slightly disappointed. He had already seen the power of world wind. He had originally hoped that it would be a world wind, but who knew it was not.

After carefully looking at the information about Return Feng, I saw that Return Feng was actually a passive energy technique of the Wind. It cannot be used actively and must meet certain conditions before it can be used.

Return air: It requires triggering of knife energy energy technology to produce return air effect.

Zhou Wen didn't know what the effect of returning wind meant, but he knew a sword energy technique, which was the star-slashing sword that exploded from the mutant demon general. However, the star-slashing sword was later integrated by Zhou Wen's three skills and merged into the Demon Star Wheel. Now Zhou Wen didn't know whether it was a sword energy technique.

"Since you have learned it, let's try it." Zhou Wen continued to walk forward and arrived at the hiding place of a wind world insect. While drawing the sword, he used the magic star wheel energy technique. He saw a round of blood slashing out from the bamboo sword, forming a round of blood ray. Like a saw blade of a cutting machine, it directly cut the stone pillar in half, and the wind world insect inside was also killed together.

Zhou Wen put his knife back into the sheath, and was about to walk over to check the corpse of the Fengjie worm to see if there was any crystal inside, but a flash of blood light. The wheel star wheel that Zhou Wen had slashed out before actually flew back upside down. Fortunately, Zhou Wen reacted quickly enough and dodged, otherwise he would be slashed by his own energy skills.

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

"What kind of return is interesting?" Zhou Wen was slightly surprised. After ordinary energy skills were cut out, they were uncontrollable.

However, the return wind skill gives the possibility of being controlled by the slashed Demon Star Wheel.

"Young Master Wen's sword aura is so weird, it seems to be somewhat similar to the legendary spiral sword aura, but it is not very different. The spiral sword aura wins with skills, and the sword aura goes through an arc, which is difficult to understand, but it is not enough to destroy. Your sword aura is extremely domineering but weird, which makes people unable to defend against. If I hadn't seen this sword, I would never have thought that the sword aura could return, and I would most likely be severely injured or even die." Lu Yunxian said.

"I haven't learned it for a long time and haven't mastered it well 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: "Warning on the battlefield is about killing with one blow. Everyone tried their best to fight, but suddenly a knife was slashed from behind. I am afraid that few people can avoid it."

"Okay." Zhou Wen nodded: "Let's talk about it later. It's more important to find An Sheng and the others now."

Zhou Wen is quite familiar with the inside of the ruins. He deliberately took some roads to kill the wind world insects before. Now he has obtained the wind crystals he wants, and the wind world insect crystals have also been absorbed. He no longer takes a detour and heads towards the entrance of the underground passage.

"Young Master Wen, is it the underground entrance where Liu Chengzhi... no... Mei said..." Lu Yunxian pointed to a broken building.

The building is square like a stone box, with only one side empty. From the empty side, you can see a stone step leading to the 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 its back has wings, and the other on the right is like a bird, but its head is like a bull-like horns.

"It should be here." Zhou Wen of course knew that this was the entrance to the underground passage. In the game, he had been here many times, but he had never been in.

Not seeing An Sheng and the others here disappointed Zhou Wen, who had been expected, for a long time, so he had to enter the passage to find them.

"I don't know if this thing can replace the function of the stone tool?" Zhou Wen glanced at the stone eggs in the chaotic space, and felt a little depressed.

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

"Don't go in first. There are many crises here, so it doesn't matter if we fall into it. If we lose the stone tool, it will be more than worth the loss." Zhou Wen said.

"What should we do?" Lu Yunxian asked.

"Let's wait for a day or two first. If Ansheng hasn't come out yet, we'll go in." Zhou Wen needs time to understand the situation in the underground passage, otherwise he will die if he goes down.

After all, he is only a legendary level, and his cultivation is not strong enough to force himself into like An Sheng and Ouyang Lan. In case of an accident, he is not strong enough and he may not be able to cope with emergencies.

Lu Yunxian now follows Zhou Wen's lead. Since Zhou Wen said that, he has no objection.

"You are here to wait for An Sheng and the others to come out, I will clear out all the insects in the ruins so that they will not encounter trouble after they come out." Zhou Wen was about to leave, but suddenly heard a strange sound from the underground passage.

Zhou Wen listened with his ears. The sound was a bit like the sound of a train driving on the rails. It was very regular, as if there was a train running underground, and the sound was getting louder and louder. Looking at the dark stone steps, it seemed that a train would rush out from it at any time.

"It's a pity that Diting is evolving, otherwise with its ability, you can tell what's going on inside." Zhou Wen has now begun to miss Diting's ability. That ability is too far-reaching and can solve many problems.

"If I remember correctly, there was no railway passing by here before, so there shouldn't be any trains. Is there anything similar to a train in myths and legends?" Lu Yun listened for a while and felt that the sound was like a train.

Zhou Wen shook his head and said nothing. In this era, he would not find it difficult to believe that a spaceship was driven out from the underground.

The two of them stared at the stone steps vigilantly, which was pitch black inside, like the giant mouth of a hell monster, and could not see anything. The sound of the clanging sound became louder and louder, as if a train was about to drive out.

Zhou Wen and Lu Yun looked at each other, and both of them stepped back and stood on both sides of the stone stairs. If a train rushed out inside, they would not directly hit them.

As the sound got closer, Zhou Wen felt that a train was about to rush out. In the darkness, Zhou Wen seemed to see a locomotive light flashing.

"There is really a train below?" Lu Yunxian also saw the light and couldn't help but say in surprise.

"I don't know if it's a train, but that thing is about to come out, be careful." Zhou Wen summoned the Dark Doctor out and asked him to attach himself to him in a soul state. Then he used the Dark Doctor's Perspective Light skill to look into the dark passage.
