Lu Zhan grabbed the two ichthyosaurs and threw them into the sword pool, the strange fire in the sword pool quickly wrapped the two ichthyosaurs, the tongue of fire rolled quickly on the ichthyosaurs, and the two lively ichthyosaurs struggled in the pool for a while and then remained silent.

Then Lu Zhan followed the method taught by Feng Baimei, and used different different fires and different fires to temper the two ichthyosaurs.

When Feng Baimei taught them the quenching technique, she once said that the more types of different fires used in quenching the "cyclone cannon", the more powerful the quenched "cyclone cannon" became.

There are two kinds of strange fires in the public sword pool in the "Little Mirror Lake Branch".

However, there are four kinds of different fires in Lu Zhan's sword pool, from the "Extremely Cold Ice Flame" collected at the earliest, to the purple strange fire collected from the sword pool on the "Floating Immortal Island", as well as the "Earth Leyline Yin Fire" received from the "Corpse Puppet King", and the "Black Spirit Evil Fire" obtained from the enemy Huo Tianqiu.

Now, in order to quench the "Cyclone Cannon", Lu Zhan put the "Red Lotus Industry Fire" on the "Fire Phoenix Liaoyuan Armor", the "Purple Gold Thunder Fire" on the "Wanhua Lotus Platform", and the "Void Illusory Fire" of the small mirage into the sword pool, and the seven different fires quenched the "Cyclone Cannon" together.

In addition to the main material ichthyosaurus, in the process of quenching the cannon, Lu Zhan also added those additional auxiliary materials that were collected, so that the attributes of the "cyclone cannon" could be enriched and its power could be enhanced.

In this way, he concentrated on quenching the "cyclone cannon" in his cave, during which the sword slave would also come to take a look and instruct him on some quenching techniques by the way.

Three months later, more than 50 "cyclone cannons" were successfully quenched.

These newly quenched "cyclone cannons" are only more than two inches long, the shape is like two small jade statues of double dragons coiled together, the whole body of the cannon is crystal clear, flashing with the brilliance of the yellow and green of the glow, and the upper end of the two intertwined dragon heads also faintly emerges a round of blue halo, the shape is very delicate and gorgeous.

Since these "cyclone cannons" were tempered by Lu Zhan's own hands, he was able to manipulate them to act according to his consciousness with his divine thoughts alone.

After the quenching was successful. Lu Zhan left the cave and returned to the real world, and at this time, most of the students in the Black Iron Class had also completed their respective quenching work, and only two students were still in the final finishing touches.

While waiting for the last two students, those who had already completed the quenching cannon took out their own "cyclone cannons" for everyone to enjoy.

The "cyclone cannon" quenched by Zhou Binglin was like a simple ancient sword, and I saw that the cannon body was six feet long, and the cannon body was surrounded by a snake-like relief pattern, and the cannon body faintly flashed with a layer of blood-colored light.

Fan Qingqing's "cyclone cannon" is like a dead old tree. At the top of the old tree there were two black branches, and a few shriveled fruits hung from them.

Long Tianao's "cyclone cannon" is like a naked statue of a woman, I saw the woman scratching her head and posing, bare-chested and exposed, and her posture was very sultry, but that face really didn't dare to compliment, with small eyes and a big mouth and a lion nose, especially a big mouth, and a few long teeth sticking out of it. It's terrifying.

Ximen Feixue's "cyclone cannon" is like an eye, but when he sees a circle of golden-colored pupils in that eye, it is like a cat's eye, with a trace of weird and demonic aura.

Qingyin's "cyclone cannon" is like a phoenix with wings spread high, and this colorful phoenix is draped in color. A colorful rainbow circle flashed above the phoenix crown, and a purple flame burned between the wings, which was very gorgeous and dazzling.

Just as everyone was showing their works, Feng Baimei and Zheng Jun walked over with the last two students who had successfully quenched their guns.

"Ladies and gentlemen. Feng Baimei said: "Your quenching work has come to an end. Your caves now have their own 'cyclone cannons', but how do you inject the gas into the 'cyclone cannons' and launch them smoothly?

Some students will say. As long as the pre-emptive weather machine is injected into the 'cyclone cannon', the 'cyclone cannon' will naturally turn the injected air into a beam of light.

Yes, it's that simple in theory, but it's not so easy to implement in practice.

Firing the 'Cyclone Cannon' requires a lot of skill, and if you inject the gas machine into the 'Cyclone Cannon' to change the gas machine differently, it will produce different firing effects. If you only inject the qi machine to shoot a beam in a simple way, the beam form it emits is very simple, and it will not be very powerful......"

Lu Zhan remembered the scene when the sword slave taught himself to launch the "cyclone cannon" on the "Falling Star Continent", when the sword slave set up some temporary "cyclone cannons" for him in the way of drawing a small array diagram on the "Outer Demon Temple", and those cyclone cannons themselves injected inward in a very simple way, so the power of those "cyclone cannons" was not great.

After the battle with Tong Hao and General Qinghe, those temporary "cyclone cannons" have disappeared. Now, he has his own "cyclone cannons", and they are all highly mobile floating cannons. Now that everything is ready, it's time to learn more advanced artillery skills to fire cyclone cannons, so I listened to the second half of Feng Baimei's course very seriously.

I saw Feng Baimei release a "cyclone cannon" shaped like a rose and said: "This cyclone cannon is the cyclone cannon in my cave, let's see me demonstrate, how different gas changes can have different firing effects? First of all, I injected a gas machine into the 'cyclone cannon'. ”

I saw that she aimed her palm at the back end of the rose-shaped "cyclone cannon", and a stream of gas was injected into the "cyclone cannon" from the palm of her hand, and she saw that the front end of the "cyclone cannon" shot out a column of silver light point, and the light point flew out ten zhang away and then disappeared, obviously the power of this cannon was very weak.

"See, no," Feng Baimei said, "If you simply inject a gas machine into the 'Cyclone Cannon', the attack beam fired will be very powerful. However, if we split a gas machine into two thinner gas machine wires, and when we inject these two gas machine wires into the 'air cyclone cannon', they will produce different trajectory changes, what kind of effect will the attack beam fired from this be achieved?"

As she spoke, she aimed her palm at the back end of the "cyclone cannon", and the students saw that the qi machine emitted from the palm of her hand had become two thinner gas machines, and one of the two gas engines was sent out in a wave-like shape, and the other was sent out in a spiral shape, and the two gas engines with different trajectories were injected into the "cyclone cannon" at the same time, and then they saw that the front end of the "cyclone cannon" "buzzed" and shot out a silver and orange beam, and the beam flew out fifteen zhang away before disappearing.

Feng Baimei looked at the students and said: "I divided a gas machine into two lanes, and let these two gas machines change different running trajectories, so that the power of the beam emitted is obviously a little stronger than the first one, now, I will decompose a gas machine into five gas machine filaments, and let these five gas filaments also be injected into the 'cyclone cannon' with different running trajectories, what kind of beam will be shot at that time? ”

Feng Baimei sent out the five thin qi machines in her palm, but she saw that the trajectories of these five qi machines were different: the first was spiral, the second was corrugated, the third was straight, and the fourth and fifth were intertwined like twists. The five gas engines were injected into the "cyclone cannon" at the same time, and then the front end of the "cyclone cannon" "whoosh" shot out a red and silver ring of light, and the aperture flew out twenty zhang away before slowly disappearing.

Then Feng Baimei evolved the gas engine into ten, twenty, and fifty trajectories of qi machine changes, and each time the "cyclone cannon" beam was emitted, there were different changes, and the more the qi machine was decomposed and finer, the more complex the trajectory of the change, and the stronger the beam effect of the shot.

The students were dazzled, they didn't expect that there would be so many mysteries just by firing the "cyclone cannon".

Long Tianao is a monkey, and after listening to it for a long time, he couldn't bear the loneliness, he whispered to Lu Zhan and smiled: "See, when Teacher Feng increased the trajectory of the qi machine to fifty, the beam of the 'cyclone cannon' she released was like a flower, and after I went back, I also evolved a beam of my own style, the beauty beam, and shot a big beauty from the 'cyclone cannon', which is guaranteed to make the opponent stunned." ”

Lu Zhan was listening intently to Feng Baimei's explanation, and he had no intention of taking care of him at all.

Seeing that Lu Zhan ignored him, Long Tianao turned his head and whispered to Li Yuerong next to him, "Do you know what kind of beam is suitable for you? I feel that the pig's head-shaped beam is very suitable for you." ”

Li Yuerong stared violently, gritted her teeth and said: "You mean that I am only worthy of launching a pig's head, I bah, you are the pig's head, and the son you gave birth to is a pig's head like you." ”

Long Tianao didn't get angry, but smiled: "I want to give birth to a son with a pig's head, but I don't have that ability on my own, why don't you give birth to a pig's head son with me?"

Li Yuerong was furious, but several girls next to her were amused and laughed.

Seeing this, Feng Baimei, who was lecturing, immediately pointed at Long Tianao and said, "You, come up for me, I will teach you how to evolve the trajectory of qi changes." ”

Long Tianao grimaced at Lu Zhan and said, "See, the beautiful teacher is going to teach me by hand, and she is waiting for me to eat her tofu." With that, he jumped on the stage.

Feng Baimei really fulfilled her promise and personally taught Long Tianao to demonstrate the trajectory of qi machine changes, and under her teaching, Long Tianao easily learned the trajectory of two or three qi machine changes. But when it came time to learn the five qi changes, he was stuck, and he didn't succeed in even trying a few times, and every time he failed, he was rewarded by Feng Baimei with a big bang on his forehead, until his forehead was knocked and swollen The boss had a bag, and he mastered the trajectory of the fifth qi machine change.
