boom!

  Three regiments of huge air cannonballs compressed by precision technology were fired from the muzzle immediately.

   During the flight of the air cannonball, even the surrounding air vibrated along with it.

  It seems to have a special suction, driving the surrounding air.

   "Empty cannon?"

   Seeing this scene, Magellan and Hannibal behind were also puzzled.

  After the fort fired, neither Magellan nor Hannibal saw the expected shells appear.

   It seems that the air gun was fired?

   "Not right."

   "It seems that something is approaching the pirate ship!"

   Magellan watched carefully, and soon spotted you.

   It seems that there is a force that is invisible to the naked eye, and it is quickly shooting at the pirate ship.

at the same time.

  On the pirate ship.

"Hahaha"

   "Is this a misfire?"

   "I think he was so scared of us that he even forgot to load the shells."

   "Thinking to stop so many of us with three forts is just a dream!"

  “.”

  The pirates who also saw the empty cannon fired from the turret all burst out laughing.

  But in the next second, what the pirates ushered in was indescribable power.

   Bang, bang, bang!

   Obviously can't see any real shells.

  Suddenly, a terrifying impact force hit the hulls of the three pirate ships.

  With just one face-to-face effort, the huge impact force shattered the hull of the pirate ship!

"what!"

  Even the pirates on the pirate ship were blasted by the force of the impact, and the blood vessels were squeezed hard, spitting out blood.

   Screaming again and again.

  Boom!

  In an instant, the three pirate ships, starting from the middle of the hull, turned into pieces of debris.

  Three pirate ships were directly blown into countless pieces!

  The pirates on the ship were dead or wounded.

   Those who survived fell into the sea without a foothold.

  Finally, the fragments of the pirate ship sank into the sea together.

  “.”

  In an instant, the three pirate ships were turned into scum, and the yelling and cursing of the pirates in the rear stopped instantly.

   Magellan, Hannibal, seeing this situation, their jaws almost dropped.

"what happened?!"

  Hannibal rubbed his eyes vigorously, and asked in disbelief.

  Hannibal hasn't seen what happened, the three pirate ships just disappeared?

"Air!"

   "It's an air cannon!"

   After all, Magellan was more informed.

   Suddenly came over immediately.

  Three new turrets are not without shells, nor are they empty.

   Instead, what it fires is an air cannon!

   Knowing this, Magellan was even more surprised.

   The concept of air cannons has never been used in actual combat by the Navy Headquarters.

   Especially with such a powerful air cannon!

   It's hard to guard against!

   "No wonder he is so confident"

  Thinking of this, Magellan subconsciously looked at Bai Yu who was at the front.

  Looking back to Bai Yu.

   "Sure enough, one shot is enough to destroy an ordinary pirate ship!"

   Seeing the actual combat effect of the air cannon, Bai Yu muttered to himself in satisfaction.

  As Bai Yu thought, the impact of the compressed air cannon is so powerful that it can easily destroy an ordinary pirate ship!

   This is the naval battery of yesteryear, can't do it!

   Moreover, the shells fired by the naval fort also need to accurately calculate the parabolic route after launch.

   Air cannons are not.

   itself is made of compressed air, which greatly reduces the influence of gravity.

   At a shorter distance, it is enough to launch almost straight.

  The invisible air cannon also makes it impossible for pirates to see and destroy.

   "Call me all!"

   "Press it directly!"

  At this time, a voice of order came from one of the pirate ships.

   Listening to his voice, it was Kidd, the captain of the Kidd Pirates.

  Obviously, Kidd didn't believe in this evil, and planned to forcefully rush to the advancing city with the number of ships.

  Clatter.

  Under Kidd's loud order, one after another, the pirate ships speeded up and headed for the city.

  Because there is a precedent that the pirate ship was blown up inexplicably just now.

  These pirate ships added later by Hou have no intention of slowing down at all.

  Going forward at full speed, desperately trying to rush to the first floor of the sea in the city.

"continue!"

   "Aim! Fire!"

  The three pirate ships waiting for a new round approached to a certain distance, and Bai Yu gave another order.

boom!

  Following Bai Yu's order, the Maya trio once again controlled the turret, aimed and fired the air cannon.

   Bang bang bang.

  Pirate ships, and the pirates on them, were blown up by air cannons one after another and crashed into the sea.

  The battle between the two sides on the scene has completely kicked off.

  The pirate side, almost stepping on the corpses of their companions and the debris of the ship, kept rushing forward.

   As for Bai Yu, it saved a lot of energy.

  Only the three Maya and the auxiliary naval soldiers can control the fort continuously.

  In actual combat, Bai Yu also discovered the advantages of the new fort.

   Since no fuse is needed to ignite, there is no shell loading.

  The interval between firing air cannons saves more time than ordinary forts.

   Not only that, there is no gunpowder burning, and the muzzle does not need to worry about overheating and unusable.

   Can sustain continuous bombardment!

  There are only three forts, in line with the geographical advantages of Shangjin City.

   For a while, it actually blocked the joint attack of the three pirates.

  Bai Yu Fang Haijun's morale soared.

   On the other hand, the three-party pirates no longer had the arrogance and arrogance they had at the beginning.

   "Trash!"

   "Get out of the way!"

   Right at this moment, a pirate walked out of the bow of a pirate ship that was closer to the city.

  Purple hair and white pupils, with bangs on the right side blocking one eye.

  He wears a white and green horned hat on his head.

   Impressively one of the Flying Six Cells of the Hundred Beasts Pirates.

  Devil Fruit Animal Department · Dragon Dragon Fruit · Ancient Species · Spinosaurus form ability user.

   Peggy Wan!

  Under Peggy Wan's scolding, the surrounding pirate ships immediately moved out of the way, allowing Peggy Wan's pirate ship to advance forward first.

   Peggy Wan was also standing at the bow of the ship, ready to deal with the incoming air cannons.

  Other pirates may not have noticed the air cannon attack.

  But Peggy Wan, one of the Flying Six Cells, could see it clearly.

   Peggy Wan is also confident that he can block the weird air cannon and help the large army advance into the city.

   Return to Bai Yu's side.

   "Are the Flying Six Cells of the Hundred Beasts Pirates?"

   "You guys like to give them one by one, I don't seem to have any reason not to accept them."

  Seeing Peggy Wan on the pirate ship in front of his sight, Bai Yu secretly smiled.

   "Fire!"

   Bang, bang, bang!

  Suddenly, three new turrets aimed at the pirate ship Peggy Wan was on at the same time.

  Three air cannons were fired one after another.

"come yet?"

   Perceiving the movement in the air, Peggy Wan's eyes instantly became sharp.

Roar!

   In the next second, Peggy Wan had a thought.

  The devil fruit ability is used.

  The body muscles are constantly wriggling, and scales grow out.

  The body size swelled a lot in an instant.
