After listening to Liu Xixu, he thought, "This new Formation Artifact is not difficult to refine, but it has no effect, right?"
"This kind of magic weapon really can't deal with the strong. You can refine one for me first." Jiang Ping'an said, "By the way, its name should be Array Cannon."
He wasn't sure if it would work, but he would give it a try anyway.
Liu Xixu said, "Okay, I will send it to your house after refining it."
"Thank you." Jiang Ping'an thanked.
Liu Xixu smiled and shook his head gently.
Jiang Ping'an couldn't help but said softly, "I have worked so hard for you in the past few years. First I built Azure Abyss Return to Ruins Defense Formation and All Heaven Spirit Gathering Formation, and then I built Heavenly Citadel Saint Formation. Before I can take a good rest, I have to build the teleportation array again."
"I do." Liu Xixu said with a smile.
She stood up, walked to Jiang Ping'an, and looked at Jiang Ping'an affectionately.
Jiang Ping'an stood up and put his arms around Liu Xixu's slender waist. Liu Xixu then fell into Jiang Ping'an's arms as if he had no bones.
Seven or eight days later, in the second half of the night, Jiang Ping'an suddenly noticed three very powerful demon king auras coming from the direction of Spirit Stone Mine, followed by extremely intense Heavenly Essence fluctuations coming from the direction of Spirit Stone Mine.
Jiang Ping'an immediately jumped into the sky.
Lan Yu, Lin Zihan and Palace Master Yun have also flown into the air.
"Lang Jun, Spirit Stone Mine was attacked." Lan Yu flew in front of Jiang Ping'an and said.
Before she finished speaking, Lin Zihan and Palace Master Yun also flew in front of Jiang Ping'an.
Jiang Ping'an smiled confidently and said, "It's just a three-headed demon emperor. It can't help the defensive formation on Spirit Stone Mine."
He expected that Qingqiu City sent the Nine-Tailed Celestial Fox Demon King to test whether Spirit Stone Mine's defensive formation was the real Saint Rank formation.
As he spoke, he sensed that three demon king auras in the direction of Spirit Stone Mine had quickly escaped.
"They're gone." Lin Zihan said.
Palace Master Yunshui said, "It is probably to test Spirit Stone Mine's defensive formation."
Half an hour later, three Heaven's Mandate Sect disciples flew back to Ping'an City from Spirit Stone Mine and reported to Jiang Ping'an that Spirit Stone Mine was attacked by three huge Nine-Tailed Celestial Foxs. The defensive formation blocked the attack, and the three Nine-Tailed Celestial Foxs quickly left.
"Tell Li Chengfeng and Zhu Yan that this is Qingqiu City's test. There is no need to panic. Everything is business as usual." Jiang Ping'an said.
On Spirit Stone Mine, Jiang Ping'an arranged for Li Chengfeng and Zhu Yan to lead a thousand monks to guard it.
Five or six days later, Jiang Ping'an was in the courtyard, letting Creation Furnace automatically refine elixirs while refining Soulshock Flying Sword. Ye Wenxing approached and reported, "Master, Madam Ye is asking for an audience."
"Invite her here." Jiang Ping'an ordered while continuing to refine the flying sword.
"No." Ye Wenxing Fu Shen responded, then turned and left.
After most of the tea time, Ye Wenxing brought Liu Xixu to the yard.
At this time, Jiang Ping'an had finished refining the flying sword, Spirit Pills had also finished refining, and put Creation Furnace away.
After Ye Wenxing stepped back, Liu Xixu walked up to Jiang Ping'an and said directly, "Chen Zhou, Array Cannon, I have already refined it."
"So fast? That's great!" Jiang Ping'an said happily, "Sister Xi Xu is indeed a formation wizard who is rare to see in ten thousand years!"
He did not hesitate to give Liu Xixu emotional value.
Liu Xixu was happy in his heart, and said modestly on the surface, "You are exaggerating in your praise. I am at best a formation wizard who only comes across once in a thousand years."
Jiang Ping'an smiled and said, "It must be a rare occurrence in ten thousand years."
Then, he offered Top-Grade Treasure Ship, invited Liu Xixu to board the ship and said, "Let's go outside the city and try the power of Array Cannon."
Liu Xixu was also quite looking forward to it, and she flew onto Top-Grade Treasure Ship.
So, Jiang Ping'an drove Top-Grade Treasure Ship, took Liu Xixu and flew out of the Ye Manor, flew out of the palace, flew out of Ping'an City, and flew in the direction of the Black Abyss River.
However, Array Cannon is a secret magic weapon. Jiang Ping'an deliberately stayed away from Ping'an City for more than two thousand miles before letting Top-Grade Treasure Ship land.
After landing on a mountain, Liu Xixu took out the Array Cannon she had refined.
I saw that Array Cannon has a relatively large circular base with dense array patterns engraved on it. A thick cannon barrel was set up in the middle of the circular base. The barrel is about one foot long, with dense formations engraved on the inside and outside, making it look bulky.
Liu Xixu took out an iron ball with a diameter of about one foot, put it in through the mouth of the gun barrel, and then took out three Top-Grade Spirit Stone pieces and put them into the groove of the circular base.
"Start the activation." Liu Xixu said to Jiang Ping'an, and then pinched the magic formula to activate Array Cannon's formation.
I saw Yuanli flowing crazily on the dense array patterns on the circular base, and the Yuanqi contained in the three pieces of Top-Grade Spirit Stone was absorbed in the blink of an eye.
The next moment, the thick barrel lit up, emitting a green light.
When the green light emitted by the barrel reached its peak, the iron ball in the barrel flew out from the barrel at an astonishing speed and shot towards a higher mountain peak more than ten miles away, dragging red light with it.
The iron ball flies at high speed, friction with the air generates heat and burns it red.
Boom——
The mountain peak was hit by an iron ball and a large piece of rock collapsed.
Seeing this, Liu Xixu said in disappointment, "The power is average, roughly equivalent to a blow from monk Law Manifestation Realm. The activation time is too long, the accuracy is average, and it is almost impossible to hit the enemy."
Jiang Ping'an smiled and said, "The first test is already very good. We can improve it further."
Liu Xixu turned to look at Jiang Ping'an, and Jiang Ping'an continued, "I suggest making the barrel bigger and longer so that the iron ball can gain a longer acceleration distance."
This Array Cannon is made based on the electromagnetic gun principle. The speed of the iron ball shot out is obtained by continuously accelerating the gun barrel. If you want the iron ball to come out of the barrel faster, you need to increase the thrust acting on the iron ball and the acceleration distance of the iron ball.
"This can be improved." Liu Xixu nodded.
Jiang Ping'an added, "Change the iron ball to Mystic Iron Ball."
He noticed that the iron ball was burning red. The Array Cannon he needs can blast Pudu Mountain. The cannon must be ejected extremely fast, at least ten times the speed of supersonic speed. Ordinary iron balls cannot resist it. The iron ball may burn into molten iron before it hits Pudu Mountain.
In addition, the density of black iron is ten times that of steel. Under the same weight, Mystic Iron Ball is ten times smaller than the iron ball, and the air resistance it encounters after exiting the chamber will be about ten times smaller.
Liu Xixu shook his head and said, "If the iron ball is changed to Mystic Iron Ball, although the thrust generated by the barrel is greater, the exit speed of Mystic Iron Ball may be about three times slower, and the power will be greatly reduced."
"Not necessarily." Jiang Ping'an smiled, "Speed is certainly important, but weight can also increase power."
Thrust multiplied by distance is equal to the work done by thrust. If the thrust obtained by using Mystic Iron Ball is greater, the power of Mystic Iron Ball should be stronger when the barrel length remains unchanged.
Liu Xixu: "Then use Mystic Iron Ball instead."
Jiang Ping'an added, "In addition, in order to facilitate portability, the gun barrel was changed to be spliced into sections."
"The gun barrel is spliced in sections?" Liu Xixu shook his head and said, "It can't be done."
Jiang Ping'an finally suggested. "Then change it to allow the use of mana."
He believes that the instant power provided by Essence Stones is not strong enough.
"It can be improved." Liu Xixu said, "But if it is changed to using mana, it will be even more useless."
Jiang Ping'an smiled and said, "It doesn't matter, just experiment, don't be afraid of making mistakes."
