The machine gun and the front laser beam are the two most powerful weapons of the fighter jet, but these two are obviously unable to cause fatal damage to the fire dragon, they can only injure it.

Lydia couldn't help but focus her eyes on the inconspicuous black button on the fighter's operating console.

The first-generation aircraft she was riding was quite special. It had undergone special modifications and had an additional bomb-dropping function compared to other fighter planes.

However, the dean had told her before she left that the equipment loaded on the fighter plane was extremely powerful and dangerous. If she was not careful, it might cause irreversible consequences. She must use it only when she receives an order when the situation is most critical.

Although Lydia didn't know what it was, she knew it must be something very powerful...

Should we call this a crisis situation now?

If this continues, everyone will be defeated by this dragon!

Just as Lydia hesitated, a voice sounded beside her.

"Now is not the time to use that!"

The sudden sound scared Lydia so much that the fighter plane almost crashed into the airbag of the airship next to it.

"It seems that your driving skills need more training." Lin En, who appeared inexplicably in the co-pilot seat of the fighter plane, said disappointedly.

Lydia rolled her eyes. She was concentrating on how to deal with the fire dragon, but a voice suddenly appeared beside her. She was scared to death! However, Lydia did not refute or complain, but said in surprise. "Dean, why are you here?"

"I asked the alchemists to set up a small magic on this fighter plane, which can project some magic power and willpower over when necessary." Lin En explained. This fighter plane was originally one of his backup plans, and he also made many suggestions for subsequent modifications. Naturally, it was impossible not to make some preparations.

"Then what should we do now?" Lydia asked with a frown. The dragon was too difficult to deal with. She had tried her best but still couldn't kill it.

"Let me prepare the magic to kill this dragon. You try to get as close as possible and delay some time!" Lin En said directly.

"Okay!" Lydia's frown suddenly relaxed. She has always had 100% trust in the dean, and immediately drove the fighter plane towards the fire dragon again.

Lin En disassembled the power supply system of the laser launch device and took out a ruby ​​placed inside.

The laser launching device installed on the fighter jet can release a fourth energy level laser beam with a diameter of about 0.3 mm, which is already a special grade!

Can tear steel more easily!

Such strength can only barely break through the dragon scales within 30 meters, and cannot cause fatal injuries, which shows how high the defense of this thing is! Then he can only take the risk and try to upgrade it to the fifth energy level!

The so-called five energy levels of laser light correspond to the five orbits of electrons in atoms. The principle is that electrons first absorb energy, jump from low energy level to high energy level, and then fall from high energy level to low energy level. In this process, the absorbed energy will be released in the form of light! The reason why he did not try to raise the laser beam to the highest energy level before was because the state of the fifth energy level was difficult to control. If the absorbed energy was slightly higher than this range, the element would directly turn into a plasma state. If it was slightly lower, it would immediately fall back to the fourth energy level.

Fortunately, there is a high-quality ruby ​​on the fighter plane that can be used to cast laser magic. Otherwise, with this state of magic incarnation, it would be impossible to release such a powerful spell.

Lynn closed his eyes and concentrated on casting the spell. The fist-sized ruby ​​kept spinning between his clasped hands.

Then, a series of reflective layers appeared around the ruby, encompassing it...

While Lin En was casting the spell, Lydia had also taken action and approached the huge lava dragon again. She no longer saved ammunition and the fierce sound of machine guns rang out again.

A series of sparks burst out and hit the already bloody body. The scales on the body kept falling off, revealing flesh and blood like lava.

The fire dragon, which was constantly harassed, was furious. It swung its tail to try to drive away the reptile, while pouring more anger on the airship.

In just half a minute, the remaining machine guns had finished firing, and the distance between the two sides had become very close. Lydia hurriedly called out, "Dean, are you almost done?"

"Okay, aim at the head and go!" Lin En opened his eyes and spoke very quickly. The round reflective mirror in his hand shook violently and could get out of control at any time!

Inside the invisible interior, the ruby ​​has shone to its utmost!

"Charge, charge!" Lydia excitedly pulled the acceleration lever to the bottom of the fighter plane, and rushed towards the huge lava fire dragon with a roar. Then, at the moment of collision, she suddenly turned and flew past the side of the dragon.

At the moment when the two sides crossed, a beam of light as thick as a hair shot out from the reflective layer! Sirid on the dragon's back also sensed the invasion of his territory, and then an extremely bright light appeared in front of him, passing directly across the dragon's body. The powerful power made Sirid feel a breath of death!

Fortunately, the beam of light only flashed by and soon disappeared, and the lava dragon under him didn't seem to be affected too much, which made Silide breathe a sigh of relief.

Snap...

The next moment, a slight cutting sound rang in Sirid's ears, and then, under Sirid's horrified gaze, the dragon-shaped gem in his hand exploded! The dragon body, which was flying with inertia, sprayed a large amount of blood, and with a painful roar, the huge dragon head was cut in half from the middle! Sirid's left arm was also cut off. It was not just the fire dragon that was hit by the laser beam, but also him. However, the beam came too fast and had already passed through his body the moment he saw it...

Lydia muttered to herself as she watched the huge dragon body being cut into two pieces and the corpse falling down like a rag.

“Amazing!”

Lin En, who was sitting in the co-pilot seat, also breathed a sigh of relief. It seemed that his theory was correct. His luck was also pretty good. The ruby ​​in his palm had completely turned into plasma and could no longer be used...
