The main body of the alchemy cannon is a hollow metal cylinder, surrounded by three metal prisms as a stable support. It is placed on a rotatable base that looks like a millstone, and is covered with dense and complex inscriptions.
To ordinary people, these inscriptions are like high-level math problems. Just seeing those symbols will make you feel dizzy, the world will spin, and you will even feel like you are going crazy looking at something indescribable.
But for those who can understand, the inscription on the alchemical cannon is actually quite simple.
"Let me take a look... Well, the city guard was right. The overall structure of the cannon body is fine, the gunpowder is dry, and the crystal sand is very pure... Sure enough, there is something wrong with the ignition inscription."
It originally took a few minutes to check, but because of Scott's prompts, Ian found the problem immediately - when Viscount Grant is fighting against the indigenous monsters, every minute is as precious as gold. He seriously Check what went wrong with the inscription: "Well, it turns out that the sixth inscription is used for ignition. It is stable, but it cannot operate in humid areas and water."
"Who maintained it? So lazy!"
There are a total of one hundred and three basic structures of inscriptions. Regardless of high or low level, almost all inscription circuits are constructed from these basic inscriptions.
The igniter of the alchemy cannon is not complicated, but generally speaking, it uses the No. 12 inscription as the main body, which is extremely prone to high heat. However, this may be a bit complicated and fails relatively quickly, so the person who maintained it last time was lazy and replaced it. Simplified into Inscription No. 6, which is more stable and simple and can be applied in a narrower scope.
"You can change it back to No. 12 or No. 11."
Ian took out a pocket knife from his pocket. Although it was not a professional inscription knife, the requirements for low-level inscriptions below sequence 20 were not high, not to mention that he did not need to meet the imperial firearms standards. He could barely use it a few times.
With the physical fitness of an Ascended Apprentice and the control he has developed over the past two months, Ian can carve out almost the most standard inscription structure.
Buzz!
And when the repair of the No. 12 inscription was completed and the light cartridge was connected, an extremely bright white light lit up, the inscription array released its brilliance, and the surging heat set off hot wind, hitting the faces of Ian and Scott.
"good!"
After wiping away his sweat and letting out a sigh of relief, this was the first time that Ian had really started to maintain. Although he had good grades, he had never been on the front line because of his young age and the protection of Elder Puder.
Now that he can succeed in one attempt, it only shows that his basic skills are indeed solid.
At this moment, relying on the exploration during the inspection and maintenance just now, Ian even roughly understood the operating principle of the alchemy cannon.
The gun body itself doesn't have anything to say, it's just an ordinary metal gun barrel, heat-resistant and strong. The real point is the structure of the base - the ignition process of the gun is quite special. It uses high-heat inscriptions to ignite the gunpowder dust, and then uses the gunpowder dust to The generated high-heat airflow hits the ubiquitous sand, instantly generating a large amount of charged dust, and detonates a second time.
Ubiquitous sand is a fine alchemical material with a light white color and a delicate and astringent feel. Under high heat and pressure, it will sublimate rapidly and turn into ultra-high-pressure high-heat plasma in a very short time, releasing extremely strong current, causing the projectile to accelerate.
This is also the principle of crystal sand explosive, a terrible lightning explosive, and if it is used as a primer to propel the shell...
"This is not an artillery gun at all...this is an electric thermal cannon!"
Realizing this, Ian was shocked again. He actually couldn't fully understand the principle of alchemical artillery. After all, in a world with psychic energy and alchemy, he had some knowledge of earth science, but he could still understand the specific physical phenomena. : "Directly using high-pressure plasma to push the warhead? Is this so crazy? The damage is completely overwhelming."
He said that, but the boy knew very well that there were many giant beasts in the Terra world for which ordinary artillery was ineffective. The giant crocodile outside the tower was a perfect example. Even if it was an electric heating cannon, if it did not hit its vital points, it would suffer. Some minor injuries.
As for Viscount Grant’s power armor? Not to mention, dodging a cannonball is probably the same as playing.
"Forget it, there will be plenty of opportunities to study the principles in the future."
Although he was a little reluctant to leave, Ian still suppressed his curiosity and stopped studying the structure of the alchemical cannon.
He turned the base of the cannon and started to activate this big killer, aiming towards Harrison Harbor, which was dark in the middle of the night and shrouded in heavy rain and strong winds.
"Can you...can you see?"
At this time, Scott carried the door panel downstairs on his body and covered it over Ian's head to prevent the boy from being disturbed by the falling lime debris. He also looked at the shooting window in front of the muzzle, but could only see a blank. The rain curtain: "Even if it hits..."
The young city guard swallowed the second half of the sentence, but Ian's eyes lit up with a water-colored halo. The boy chuckled and replied: "Don't worry, you can see clearly."
After a pause, his tone became solemn: "Besides, I can definitely hit the vital point."
Concentrating and holding his breath, Ian raised his eyebrows lightly, and the spiritual energy halo in his eyes was like the faint moonlight. This was the first time he controlled the artillery, and it was also the first time he actively pushed the spiritual energy to the limit that he could control now.
In an instant, the entire east side of Harrison Harbor was shrouded in precognitive vision, turning into a field of mist, releasing varying halos.
And the two most conspicuous ones... Viscount Grant, who is wearing etheric weapons, and the great shaman who is driving the swamp crocodile dragon, are also within the scope of his binocular observation!
"Well……"
His brain seemed to have been hit by a heavy hammer. Ian felt as if countless sparks were exploding in front of his eyes. A stream of bright red blood flowed from the corners of his eyes and nose. Even his body felt hollowed out and exhausted. It was like doing the difficult exercises required by Hilliard for more than ten hours in a row.
This is the price of forcibly spying on a large area and being far stronger than oneself.
But in contrast, two huge purple mists appeared in Ian's eyes. They were fighting and colliding, exerting their own power on each other, using flowing water, steam, mud and rocks to attack and defend.
In the direction of the Viscount's Mansion, there was still a bit of purple mist light flow.
"The second energy level...is it purple? It seems that there is really a treasure in the Viscount Mansion."
Taking a deep breath, Ian used the breathing guidance technique. He consumed the essence stored in the source species and the glycogen stored in the liver to relieve the current fatigue: "The one who is smaller but more solid is the Viscount. I don't need it. Pay attention to him and observe the crocodile dragon intently..."
With the words, the halo of mist representing the crocodile dragon gradually became thicker, and the spiritual energy responded to his own wishes.
Soon, the purple haze reflected in Ian's cyan eyes turned into an image that was constantly flowing and changing, like an image of thermal energy.
However, the most critical point is that there is an extremely obvious 'vulnerable zone' with extremely thin fog on the side of the body of this crocodile dragon made of many dark purple mist!
"Such an obvious weakness?"
Ian was startled. He really wanted to find the weakness of the crocodile dragon, but he thought it was the eyes, the base of the tail, or the soft belly. Unexpectedly, this old crocodile actually had old wounds on his body: "Look. It seems like it was cut open with a sharp sword and penetrated deep into the internal organs. Who is so powerful?"
Without thinking so much, he controlled the steering of the cannon - the base of the cannon, which usually required two people to rotate, slowly rotated under the power of Ian who used the source of matter.
Then, it’s launch!
Click, a blazing white light bloomed, and the high-heat gunpowder airflow was fully mixed with the ubiquitous sand, causing it to sublimate instantly, and a dull thunder exploded in the base of the alchemy cannon - and this thunder pushed the cannonball and ejected it from the muzzle The two-meter-long arc flames bombarded the crocodile dragon that was still fighting with Viscount Grant at a speed that exceeded the speed of sound!
boom! Following the sound of artillery fire that had not been heard for a long time, the mud shield on the left foot of the crocodile dragon splashed and exploded, causing the giant beast to tilt its body in pain.
But that was all. The furious crocodile dragon even turned its head, and its six scarlet pupils locked on the slightly tilted tower not far away.
——It works, but it misses the point!
This crocodile is simply like a moving and self-repairing hill. Unless an entire artillery unit is used to continuously bombard it, it will be difficult to cause fatal damage!
Ian silently wanted to reload. Since he missed the first shot, he would hit again. But at this moment, Scott raised a cannonball and walked over. He had already taken it out when the boy was aiming. There is an inventory of artillery shells on the side, ready to help Ian launch his second launch!
"……Thanks!"
Glancing at the resolute-looking young city guard with some surprise, Ian nodded and joined forces with Scott to quickly load the shells.
Then, facing the crocodile dragon that ignored Viscount Grant's attack and turned sideways to attack the tower, Ian once again calmly opened his precognitive vision and mentally corrected the error in the last shot.
He takes aim.
Immediately afterwards, it was launched again.
boom! The blazing white flames lit up, and the speeding shells were like meteors, tearing apart the dark night.
At the same time, with the sound of tearing and rotting leather, a big mouth suddenly burst out from the side of Crocodile Dragon!
For a moment, everyone, including Viscount Grant, was shocked to see the huge beast let out an earth-shaking, angry and painful howl, while the hot blood spurted out like a volcano, and even large groups of blood could be seen. Bits of flesh and blood spilled out!
The balance of power in the battle is now broken!
