He promised Lei Junze again before sending the senior away. Lei Junze was still very interested in them. All the Long Yuan Crystals obtained were directly exchanged for them with the Doutian Points. Of course, there was no increase in the completeness of this mission.

Lei Junze had his thoughts, and Wang Tianyu's attention to Lan Xuanyu was shocked. He also had the idea of ​​deliberately making friends with this junior. Therefore, within his authority, he turned a blind eye.

The initial gains are quite rich, enough to upgrade Lan Xuanyu and the others to level 4 Heaven Fighter. They are also likely to be the lowest-age Level 4 Heaven Fighter in previous years. They will enter the main show next, and the most critical moment is coming.

This time, Lan Xuanyu asked his friends to rest for twelve hours and filled all the supplies of the Tianyi mecha. Then he left the Longyuan Star Base again. Thirty-three Tianyi and Thirty-three fighter jets gathered together and flew towards the gray fog area.

The fighter planes were flying high in the air. They did not fly straight towards the gray fog area, but wandered around the periphery under the leadership of Lan Xuanyu. Observe the situation below.

As Lan Xuanyu expected, although the number of Yuanlongs near the base has decreased sharply due to their cleaning, new Yuanlongs have appeared in the cleaned areas far away.

This source dragon is really endless!

"Everyone, turn on the invisible mode." Lan Xuanyu ordered.

A faint layer of light appeared on the surface of the Tianyi fighter. Suddenly, the air around began to twist slightly. The Tianyi fighter continued to fly in the air, but only a faint light and shadow remained.

This is the technology of the Tangmen, and it is a new feature of the Tianyi Mecha after many adjustments and evolutions.

The stealth of fighter jets is similar to the stealth of warships. Both are caused by the special characteristics of light refraction. In addition, a special coating is added to the surface of the mecha. With the combination, it can shield a certain degree of mental detection, radar, and visual observation.

The latest federal ghost fighter is the technology used. The Thirty-Three Skywing fighter is naturally equipped without hesitation. Compared with the ghost fighter, the Skywing fighter is better in noise reduction. It can also cover itself as much as possible from the sound level.

After turning on the invisible mode, Thirty-Three Heavenly Wings no longer circled and headed straight to the direction of gray fog.

The gray fog area was almost at the other end of Longyuan Star relative to the base. Even if it was flying at full speed, it took them nearly five hours before they gradually got closer.

They did not leave so far when they were fighting. At this time, by scanning downwards through the radar, they could find a large number of source dragon groups, including many powerful existences.

The benefits of invisibility are revealed at this time, and they are flying at an altitude of 8,000 meters above the ground, and the source dragon below did not find their existence.

Lan Xuanyu was flying in front of everyone in his Tianyi fighter plane. From afar, he could see the sky in the distance was gray. It seemed that it was not fog or something, but gray-black. Judging from the news from the base, these grays were made of metal dust, so they could isolate all kinds of detections.

As for how these metal dusts are formed and what they are covering up, they are the purpose of their exploration.

As the distance got closer, Lan Xuanyu issued an order to make other Tianyi fighter planes hover and wait outside the gray fog. He had to enter and investigate by himself first.

The situation inside the gray fog is unknown. His fighter jet control is the strongest among everyone, and he has the greatest confidence to escape. His friends are responding outside and ready to support him at any time.

The only ones who are most suitable for investigation are him and Tang Yuge. As the squad leader, he is also the head of Thirty-Three Heavenly Wings. Lan Xuanyu is naturally responsible at this time.

Thirty-two Tianyi fighters separated and spread out. Lan Xuanyu's Tianyi fighters also slowed down and slowly approached the gray fog.

Just as his Tianyi fighter jet entered the gray fog range, a harsh alarm sounded. Lan Xuanyu was shocked. With the connection between the battle armor and the mecha, he was now like Tianyi. He immediately felt the various data of the mecha fluctuations in an unstable manner. Moreover, there seemed to be a repulsive force in the gray fog, which slowed down his flight speed.

This is……

The Tianyi fighter waved unstable, and it seemed that there was a risk of falling at any time. Lan Xuanyu did not dare to neglect his soul power, and released it outwardly, turning into a layer of shield to protect the outer periphery of the Tianyi mecha, isolating the gray fog.

The Tianyi fighter then stabilized, but Lan Xuanyu found that his soul power was consumed extremely fast.

magnetic field!

There is a powerful magnetic field in the gray fog formed by these metal debris. After all electronic systems enter this magnetic field, they will be greatly disturbed immediately. In other words, this is almost a prohibited area. The mecha will be greatly disturbed here.

At this moment, a harsh scream sounded, and then, while waving, a ray of light shot straight into the direction of the Tianyi fighter.

The light covered a huge range, and Lan Xuanyu was about to be unable to dodge.

The passionate dragon roar sounded, and the Tianyi fighter instantly deformed in the air and turned into the Tianyi mecha. A layer of golden scales appeared on the surface of the fighter. At the same time, both fists were blasted out, and the golden dragon-shaped energy collided with the beam.

"Boom--" The powerful impact force made Lan Xuanyu's sky-wing mecha fly backward. In the gray fog, a flying source dragon that was more than ten meters long had already drilled out, and beams of light continued to shoot towards Lan Xuanyu.

Lan Xuanyu frowned slightly and was discovered! There is no doubt that it was the cause of the gray fog. Entering the gray fog is not only affected by the stability of the electronic system, but also the invisibility effect is also lost and he is discovered by Yuanlong.

But the gray fog could not affect his mental perception. He immediately felt that there were a large number of unknown creatures in the gray fog approaching his direction, and a sense of danger appeared instantly.

Without hesitation, a ball of yellow light condensed, bursting outward, turning into an existence like a wall blocking behind him. He himself controlled the Tianyi mecha to instantly turn back into a fighter plane, turned around, accelerated with all his might, and rushed out of the gray fog.

Undoubtedly, this gray fog is the home court of the Source Dragon. The abundant metal elements inside have made the Source Dragon's combat power soar. Just now, this level seven source dragon threatened him a little. Moreover, the control of the fighter will be severely disturbed, and the number of enemies is unknown, and it will be detected. Please exit first.

Although it was only a short time to enter the gray fog, Lan Xuanyu had already obtained a lot of useful information.

The Tianyi fighter speeded up, and he didn't enter much. He almost accelerated violently and rushed outside the gray fog.

After rushing out of the gray fog range, you can naturally see the situation below. Lan Xuanyu found that a large number of source dragons had gathered towards this side. He did not dare to neglect, and the fighter accelerated again, soared upwards, and raised upwards. During the process of rapidly rising up, the invisible device was re-activated.

Behind him, more than thirty flying source dragons roared out and chased them in the rear. These source dragons were all above level six, and level seven accounted for the majority.

The invisible effect gradually appeared. With Lan Xuanyu accelerating with all his strength, it was the soul power and the energy of the mecha itself that was speeding up. As the distance gradually opened, the source dragons lost their lock on him.

Lan Xuanyu opened the team channel and said, "Can I hear my voice?" He was not sure whether his communication was damaged by magnetic field interference.
