The day after the withdrawal of the army from Yanmen Pass, the third day after the war report was issued.

Directly above Panlong City, at an altitude of 10,000 meters, the Red Dragon was still parked in that position, motionless.

After the stealth system is activated, the Red Dragon merges with the surrounding sky, and there is almost no possibility of spotting the Red Dragon unless it crashes head-on with the Red Dragon.

I saw that the plywood in the middle of the Red Dragon was separated from the left and right, and a pitch-black giant cannon slowly rose, with a total length of about 30 meters and a muzzle diameter of nearly 20 meters.

The black cannon slowly rose, stopped at a certain height, and then began to adjust its position left and right, and the muzzle of the cannon was finally aimed at the west of Panlong City, which was a magnificent palace, standing on a small hillside, which was the dormitory where the mother of the dragon clan and the Dragon Emperor lived.

The Zhushen cannon began to charge, and purple points of light appeared in the black muzzle, and purple points of light flew from all directions, gathering here, and in a minute, the barrel was finally filled.

On the deck of the Red Dragon, Lin Nan, Tu Shan Yueyue and No. 17, dressed in "Huang" robes, everything was ready.

"The army has withdrawn." Number 17 whispered.

Lin Nan has been waiting for this news for the past few days, and just yesterday, he learned from the family of a certain dragon soldier in Panlong City who accompanied the southern expedition of the dragon that the dragon took an army of 100,000 and withdrew from Yanmen Pass and drove directly to Lindong City.

It is understood that in order to save time, he left 50,000 troops behind, personally led the Black Dragon Legion, galloped thousands of miles to help, and took the lead in Lindong City.

"Well, it's our turn."

The Red Dragon was slowly descending in altitude, and Lin Nan, Tu Shan Yueyue and No. 18 walked to the edge of the Red Dragon deck, and looked down from the Red Dragon, Panlong City gradually became clear.

"Let's go."

As soon as Lin Nan's voice fell, he took the lead in jumping off the Red Dragon and fell from a height of 10,000 meters.

"It's really crazy, and only this princess is so crazy with you."

Tu Shan Yueyue shook her head, followed by Lin Nan and jumped off the Red Dragon.

No. 17 was the last one, with a pair of silver mechanical wings born behind him, and jumped down following the footsteps of Lin Nan and Tu Shan Yueyue.

In this operation in Panlong City, there were three participants, Lin Nan, Tu Shan Yueyue and No. 17, and No. 18, who was weaker in combat, consciously stayed on the Red Dragon, responsible for the response, and was ready to slip away at any time.

[Charge completed], four big words appear on the cab screen.

"God Killer Cannon, charge complete."

"Open fire."

No. 18 pressed a red button, and the entire air battleship shook violently.

Almost at the same time as Lin Nan and the others jumped down, the 18th fired the Zhushen Cannon.

The God Punishment Cannon, which had already been prepared, shot out a purple beam of light with a diameter of about twenty meters, and the purple beam went straight ahead and flew towards the huge palace directly west of Panlong City.

Boom, the cannons of the gods accurately hit the golden palace, and the palace exploded on the ground, and was instantly overwhelmed by the raging waves of fire, and everything was wiped out in an instant.

A small mushroom cloud rose from the flat ground and soared into the sky, and the entire raised hillside was leveled.

The Dragon Emperor's Palace was razed to the ground without warning, and the entire Panlong City was in chaos, and some dragon soldiers reacted quickly, turned into dragon bodies and raised their wings, and flew in the direction of the fire of the cannons.

After seeing the destruction of the Dragon Emperor's Palace, No. 18 did not hesitate, driving the Red Dragon to turn around and run, her task has been completed, successfully attracting the attention of all the dragons in Panlong City, and buying time for Lin Nan and others to sneak attack the Lock Dragon Tower, and then just hide the Red Dragon and not be found by the Dragon Clan.

At the same time as the Dragon Emperor Palace exploded, Lin Nan and Tu Shan Yueyue were still falling, but it was less than a hundred meters away from the Lock Dragon Tower, and the 17th appeared at the right time, grabbing the falling Lin Nan and Tu Shan Yueyue from mid-air, reducing the impact of the two falling.

"There's not much time for us, and it must be solved before the Mother of Dragons reacts." Lin Nan reminded.

On the 17th, he took Lin Nan and Tu Shan Yueyue and glided towards the Lock Dragon Tower, leaving the two at the top of the tower, and the two of them turned on the "crazy blood" state at the same time in the fall.

With two bangs, two blood-colored figures landed on the top of the Locking Dragon Tower, shattering the ceiling and entering the highest floor of the Locking Dragon Tower, the eleventh floor.

The eleventh floor is the control room of the Lock Dragon Tower, and it is also the core of this "prison".

From the outside, the Lock Dragon Tower looks like an ordinary glazed tower, but in fact, it has a built-in advanced prison management system of the mechanical family, the tower is full of monitoring and trapping, the cell door is automated, and there is a perfect defense system, whether it is to enter or exit, it is extremely difficult.

Since he decided to make a move, Lin Nan naturally couldn't attack from the front unprepared, and the most important part of the plan was to take over the control room and use No. 18's excellent hacking technology to disarm the defense system of the Dragon Tower.

In the control room, in the face of these two "divine soldiers" who fell from the sky, the three dragon clans who were in charge of guarding them were stunned and froze on the spot.

"You 、、、。"

Before the two dragons could react, their heads had already fallen to the ground, and they didn't even have a chance to call for help.

The heavy soldiers of the Lock Dragon Tower were all guarded on the first floor, and they never dreamed that Lin Nan and the others would come directly from the sky.

"Enemy attack, enemy attack, enemy attack 、、。"

The only remaining dragon saw that the exit was sealed and wanted to run directly through the ceiling, but as soon as it flew up, it was trampled to death by the last to arrive on the 17th.

"No. 17, I'll leave it to you here, and I'll come over as soon as I finish the task." Lin Nan whispered.

"Master rest assured, this second-rate defense system has long been eliminated on the mechanical side, and in a minute at most, I can hack into their system."

Number 17 replied confidently, walked to the console, and stretched out his right hand, the skin of his palm cracked, and a wire with a square plug came out of his palm.

Lin Nan nodded, and Tu Shan Yueyue went down the stairs on the left and right sides of the eleventh floor, and he couldn't be more relieved to hand it over to No. 17 here.
