Supreme upgrade system

"Ding, the system prompts that the host has successfully exchanged for primary refining techniques, and 100 gold coins have been automatically deducted!"

"Ding, the elementary refining technique has been automatically used and learned!"

……

"Okay, let's get to work!"

Chen Xiao muttered something, and then began to take out a kind of iron block from the system backpack, directly borrowed the fire in the center of the earth in the alchemy tower, began to use the refining technique, and began to hammer the iron block little by little.

After learning the Art of Artifact Refining, Chen Xiao discovered that it is extraordinarily miraculous. Different from ordinary blacksmithing and casting, the Artifact Refiners in this world also have their own school, and the casting method is very magical.

What Chen Xiao is learning now is the simplest one!

After the iron block was burnt red, Chen Xiao connected his hands together, streams of true energy began to overflow from Chen Xiao's fingertips, poured into the iron block, and easily cut the red-hot iron block into more than a dozen uniformly sized iron blocks. Afterwards, he pulled it with true energy and calcined it with ground fire, so that he could easily pull the iron block into the shape he wanted, with almost no waste at all.

An hour passed in a blink of an eye, and beside Chen Xiao, there were already a large number of iron bars of different shapes that were made entirely of iron blocks, etc. These were all needed for the aircraft, and Chen Xiao's refining was very hard. , I failed directly many times during the period. Fortunately, through continuous efforts, I finally got everything I needed.

After finishing all this, Chen Xiao waved his hands to pack his things, and then went out directly. After bidding farewell to Liu Tianshuo and others, Chen Xiao returned to Fenglei Inn.

After staying in the Fenglei Inn for another day, Chen Xiao chose to check out and leave in the early morning of the second day.

Outside Fenglei City, Chen Xiao turned around and glanced at the behemoth behind him, then rode a dragon horse straight into the distance.

Along the way, the dusty horse galloped for more than 30 miles, and Chen Xiao suddenly turned his horse's head, and got into the dense forest beside the mountain road, and disappeared in a blink of an eye.

As for the dragon horse, Chen Xiao just let it continue to gallop on the mountain road, and didn't care about it anymore.

There are also some mountains around Fenglei City, such as the Monster Beast Forest hundreds of miles away, but the destination of Chen Xiao's trip is not the Monster Beast Forest. He walked through the nearby hills that can hardly be called mountains, and chose a place with a cave. Chen Xiao moved in directly.

The reason why there is an inn that you can't live in is also for the sake of your future plans. If you just leave, and the things on Fenglei Villa are stolen, what do you make others think?

But if you have already left and lost your things, even if people suspect you, they can't find you, and you are gone, who can say that you did it?

Moreover, Chen Xiao still needs to find a place to test this flying tool. He can't test it in Fenglei City, right?

……

In a cleaned cave, Chen Xiao was sitting cross-legged. The cave was ten meters wide, and there were obvious traces of artificial excavation on the cave wall.

On top of Chen Xiao's head, a fist-sized moonstone was emitting a hazy halo.

This kind of moonstone is a pure natural ore, which can emit a relatively bright light, which is not weaker than an oil lamp. It is a lighting tool that many warriors like to use frequently. Chen Xiao also bought a lot this time and threw it in his backpack. Inside.

Not far away, there was a pile of bonfires roasting delicious monster meat, while Chen Xiao himself was frowning at the simple aircraft in front of him on the other side of the cave.

After three full days of production and debugging, this simple flying machine is finally done, and what makes Chen Xiao more proud is that this thing can fly from a low place to a high place, as long as the speed reaches a certain level, it can take off directly. The effect of the plane in the previous life is generally the same.

Turning in the air, etc., Chen Xiao also specially tested it, as long as he uses the true energy in his body to shoot it through the air, he can use the force of the shock to change the direction of flight.

At the beginning, I was not proficient and it was troublesome, but after the test, I was able to fly perfectly.

The most important point is that flying through the aircraft will not produce the slightest wave of true energy. Even if it flies over a group of people, as long as no one looks up, it is impossible to find that there are people on it!

All is ready except for the opportunity!

Chapter 87 Night Breakthrough Thunder City

Another seven days passed in a blink of an eye.

During these seven days, besides swallowing pills to practice, Chen Xiao was tempering the true energy in his body. It has been one and a half months since he completed the mission. Did not act rashly.

Another evening, Chen Xiao stood outside the cave, looking up at the gloomy sky covered with dark clouds, with a gleam of joy on his face.

He waited here for so many days, in addition to avoiding being suspected by those people in Fenglei City, he was also waiting for a suitable opportunity, and now, the opportunity finally came!

After so many days, even if something really happened, those people would not suspect him.

Back in the cave, he ate a barbecue in comfort. It wasn't until it was getting late that he left the cave, plunged into the forest, and galloped towards the location of Fenglei City.

Fenglei City is surrounded by mountains on both sides, and there is a large lake on the side. The location of Fenglei Villa is on the east side of the soaring Sword Peak. Apart from Jianfeng, there is a mountain forest with a height of hundreds of meters about ten miles away from Fenglei City. The area, Chen Xiao's destination this time, is the mountain forest.

About an hour later, Chen Xiao finally came here. Although it was very dark, Chen Xiao's cultivation had reached the one-star Martial King Realm, almost reaching the night vision, and the obstacles in the mountains and forests could not stop Chen Xiao in the slightest.

When I came to a cliff, I looked up at the sky, only to see that the moon in the sky had already been covered by dark clouds, and I couldn't see anything in the sky clearly, and it seemed that it would not be possible to reveal it for a while.

"It's almost there!" Chen Xiao muttered, took out a moonstone and threw it on a rock protruding from the cliff.

After doing this, Chen Xiao released the proposed aircraft with a wave of his hand, put it on very skillfully, checked it a little more, and after making sure there was no danger, he took a few steps back, and then rushed forward suddenly.

When he came to the edge of a cliff hundreds of meters high, his body exploded with qi, and he rushed out of the mountain and fell directly into the dark underground forest.

However, at this moment, Chen Xiao slightly pulled a few wires made of iron wires with both hands, and the device on his body immediately changed slightly, and it actually began to climb up little by little against the evening wind.

In the end, it flew up again, and, getting higher and higher, finally rushed into the clouds and disappeared.

In mid-air, Chen Xiao glanced at the dark forest below, and then looked into the distance.

In the haze, one can still see a dimly lit place outside the mountains in the distance, and there is Fenglei City.

This is the first time that Chen Xiao has really flown to a height of thousands of meters. At such a height, even if Chen Xiao has reached the Martial King Realm, once he falls, he will surely die. Don't worry too much.

Along the way, Chen Xiao was like an eagle, soaring high in the sky, and approached the sky above Fenglei City very smoothly.

After approaching, Chen Xiao was not in a hurry to go straight up, but circled around Fenglei City first, and after confirming that there was no problem, he raised the altitude again, drilled directly into the clouds, and disappeared.

Before, he could barely see Chen Xiao's shadow on the ground, but now he couldn't even see a shadow after he got into the clouds.

Fenglei Villa, Jianfeng! ^ cool ^ book ^ net ^

The disciples of Fenglei Pavilion stationed here were patrolling around as usual.

Perhaps it was because there had been no accidents for a long time, and the disciples on patrol now just walked around and checked to make sure no outsiders were allowed in.

As for the sky?Except for the occasional glance, I don't care at all.

Because, if a martial artist wants to fly into the sky, only the cultivation base of the Martial Emperor Realm can do it, and once a Martial Emperor strongman approaches, the three elders guarding this place will definitely find out immediately, and they don't need to worry about it at all.

When they were patrolling, they didn't find that a "little bird" flashed away from the clouds in mid-air.

The snow peak is about 800 meters above the ground. Chen Xiao is at an altitude of [-] meters at the moment. Looking down, he can see that there are still lights in the Fenglei Villa halfway up the mountain.

However, fortunately, so far, no one has really discovered him!

After circling like this for a while, Chen Xiao saw an opportunity, suddenly lowered his altitude, and landed rapidly towards the top of the snow peak.

During the descent, there was no movement, only Chen Xiao could hear the whistling wind in his ears.
