Luo Yu's decision, Ling Chen was not surprised.

Although nearly ten tons of energy crystals were brought back this time, it only relieved the pressure on the military department, and to completely solve the problem of the sinkhole, that energy crystal was far from enough.

It is certainly a bit risky to let the powerhouses of the Mixed Yuan Realm of the Ancient Martial Realm come to Earth, but it is not a risk to let the masters of the War Department go deep into the depths of the Centipede Mining Area?

Moreover, let the gods and masters go deep into the centipede mining area, and the mined energy crystals may not be able to completely block the sinkhole passage, maybe they will have to go deep into other mining areas, and they will have to have the strength of the Mixed Yuan Realm.

If the passage of the sinkhole cannot be sealed before the situation in the sinkhole completely deteriorates, it will be a real disaster for the human beings on earth.

In that case, it's better to take a risk.

In fact, it is not much of a risk to let the mixed element master of the ancient martial arts world come to the earth.

When Ling Chen brought them to Earth, there would definitely be a way to control them, such as letting them eat the elixir with Ling Chen's spiritual power, unless they were Mixed Yuan Realm powerhouses who had lived too long, they would have to listen to Ling Chen's words.

In addition, Ling Chen doesn't just let people do things, but doesn't give people benefits.

For example, the best Mixed Yuan Golden Pill, or the Elven Divine Pill, can make the martial artists of the ancient martial arts world crazy.

The martial artists of the ancient martial arts realm are more eager for the improvement of their strength than the martial artists of the earth, because it is a place where strength represents everything.

"Okay, that's it. ”

Ling Chen nodded and said, "Godfather, don't worry, this time I go to the Ancient Martial Realm, I will definitely have to deal with the mixed master of the Ancient Martial Realm, if my mind is not normal, I will definitely not bring it to the secular world." ”

There was a slight chill in Ling Chen's tone, and Luo Yu felt a chill in his heart when he heard it.

If a mentally abnormal hybrid master is not brought to Earth, will Ling Chen stay in the Ancient Martial Realm?

It must have been slaughtered!

When he returned to the military headquarters, Luo Yu drove back alone, and Ling Chen didn't go back with him.

When he returned to Xichuan City this time, Ling Chen did not plan to use the helicopter of the military department, nor did he plan to drive.

He's going to try, fly back with the wings of the sky!

The speed of Sky Wings is not necessarily much slower than that of an airplane, but it will consume some True Qi.

If the cost is calculated, the consumption of True Qi to fly is higher than that of a helicopter flight, but for Ling Chen, the consumption of True Qi is not a big deal.

I want to go to the ancient martial arts realm for revenge, and the strength realm can't be improved for the time being, so I fly back by myself, and I happen to be more proficient in controlling the wings of the sky.

Ling Chen took off from Yanjing at two o'clock in the afternoon, and when he arrived in Xichuan City, it was almost seven o'clock in the evening, and the flight speed was still a little slower than that of the plane.

However, Ling Chen did not deliberately pursue speed in order to be more familiar with the Heavenly Wings, and in order to reduce the consumption of True Qi, if he flew at full speed, it was estimated that he would be able to arrive nearly an hour earlier.

On the night of Ling Chen's return to Xichuan City, a video broke out on a well-known website, which was quickly forwarded on various media platforms and even spread abroad.

The video is very short, less than ten seconds, and the image is not very clear, and the video captures a UFO.

This UFO flies at a high altitude and has a pair of gray-white wings, and it is impossible to tell if it is a human or some other species underneath the wings.

Below this UFO video, there are countless comments, basically discussing the origin of UFOs.

Some believe that alien creatures have come to Earth, others believe that it is some kind of large bird mutation, and others believe that humans have been equipped with the wings of the latest technological inventions.

The next morning, Su Jing and the others also saw the video of the UFO, others didn't know what was flying in the video, but Su Jing and the others recognized it at a glance, the UFO was Ling Chen!

"Hold the grass, can this be discovered?" Ling Chen looked at himself flying on the computer screen with an incredulous expression.

In order not to shock the world, he took off in the uninhabited barren valley southwest of the military headquarters, and his flight altitude exceeded 3,000 meters, and the human eye would not detect him at all.

But unexpectedly, it was still discovered, and a flight was filmed by everyone.

Fortunately, the definition of this video is not high, and the camera is so far away that you don't even know if it's a human or another species, let alone recognize who it is.

After sighing for a while, Ling Chen didn't bother with the video, how others liked to guess how pigs, he had no interest and no time to pay attention.

He was about to leave the earth to go to the Ancient Martial Realm, and it would take a few months to come back this time, so of course Ling Chen had to accompany his girlfriend before leaving.

Five days later, Ling Chen called Gu Tianzong, Senior Brother Gu, and set off for the Ancient Martial Realm, officially starting a journey of revenge!

Because they flew back to Xichuan City from Yanjing to Xichuan City, they were all filmed flying videos, and this time they went to the Valley of Death, and Ling Chen and the three of them honestly took a plane and a train.

When he came to Gelmu, it was already night, and when he returned to the ancient martial arts realm in the past, Ling Chen rented a car in Gelmu to go to the Nalengle Gorge, but now Ling Chen has successfully condensed the wings of the sky, so he doesn't have to bother renting a car.

From Gelmu to the Nalengler Canyon, it was a deserted area, and it was night again, so Ling Chen didn't have to worry about anyone treating him as a UFO.

With the wingspan of the Wings of Heaven, it is no problem to fly with Bai Yuyao and Gu Tianzhong, it is nothing more than consuming more True Qi.

However, the take-off place must be found in a place where no one can see it.

Coming out of the Geermu Railway Station, Ling Chen led Bai Yuyao and Gu Tianzong towards the uninhabited suburbs.

When he arrived at a place where there were few people, Gu Tianzong asked, "Senior Brother Ling, let's ...... Go back so soon?"

Gu Tianzong wanted to ask for a long time, but there were always others around, and he didn't have the opportunity to ask until now.

When he came out of the ancient martial arts world, it was expected that he would be able to go back for more than two or three years, but it had only been more than a year and less than two years, and he was going back to take revenge!

"The revenge of destroying the door was avenged one day earlier, and Master and they were under the Nine Springs, and they could also be seen one day earlier. Ling Chen's tone was calm, but there was a faint hint of killing.

"Senior brother, are you ...... now What's the strength?"

Of course, Gu Tianzong hoped to get the great revenge of his master as soon as possible, but what he was worried about was whether the current Ling Chen had the strength to call the Bandan Palace.

"The peak of the middle of the mixed element. Ling Chen replied truthfully.

Gu Tianzong's body trembled slightly, and he said in a trembling voice: "Senior brother, our enemy is the ...... of the Dan Palace."

Ling Chen knew what Gu Tianzong was going to say, and without waiting for him to continue, he intercepted his words: "Senior Brother Gu, I have broken through from the Psychic Realm to the peak of the middle stage of the Mixed Yuan this year, and Yu Yao has also broken through from the peak of the late Dan Jin to the Divine Realm, and you ...... It's not even a high-grade realm, it's left behind!"

Gu Tian was speechless, he had been in the secular world for more than a year, from the early stage of Dan Jin's cultivation to the peak of the late Dan Jin, would this cultivation progress be despised?

However, compared to Ling Chen and Bai Yuyao, his cultivation progress did fall behind......

No, it's not about your own cultivation progress now!

"Senior brother, in fact, revenge, and I am not in a hurry to ...... for a while," Gu Tianzong said worriedly.
