Li Xiucheng led his team through a mountain tunnel that only fighter planes could pass through, in order to avoid any mistakes in the mission.

The automatic navigation and driving systems of all team members' aircraft are activated.

Li Xiucheng fully agreed with this plan to deceive everyone.

However, Li Xiucheng couldn't help but complain about the name.

He agreed with the first two words. He thought it should be called "burrowing underground". At least his troops and the other two troops were basically walking in holes or tunnels, just like rats digging holes.

However, this is also thanks to the help of the Payadi guerrillas, who followed the other two forces.

The Payadi guerrillas informed them that they had undercover agents inside the Goroya Fortress.

This let them know where and which facility the primary target was.

The other two troops had already taken action a few days earlier than them and are now ready to go, waiting for their unit, code-named "Chuantengu", to rush out of the exit.

After making a big fuss in the Goroa Fortress to attract the enemy's attention, the second unit [Drilling Dogs] carried out ground fire attacks and ground force breakthroughs to cover the infiltration of the first unit [Shadow Mad Dogs].

The Tengu Force is currently flying. The Impulse Gundam and Savior Gundam were originally battery-powered machines, but for this mission, they were specially replaced with the third-generation Minovs super-energy thermonuclear reactor.

The purpose is that once we enter the Goroya Fortress, in order to have enough energy to fight a long battle, we must replace it with the Minovsky super-energy thermonuclear reactor.

With the help of the automatic navigation driving system, we passed through the mountain tunnel safely and without any mistakes.

"Master, we have 30 seconds left before we pass through the exit. Should we detonate the bomb at the exit now to make the exit wider and allow Ms in fighter form to pass through?"

"Detonate."

"receive."

The exit exploded, and the hole that was originally impossible for a fighter plane to escape from became larger due to the explosion of the bomb.

In the exploding dust, the Tengu troops rushed out of the dust.

The radar in the Goroa Fortress discovered the Tengu troops (the communication facilities, radar, etc. in the Titan Wall were not affected by the neutron jammer) and immediately reported to the commander.

Lieutenant General Gustavo looked at the three-dimensional screen and couldn't believe it. The intricate tunnels between the mountains had been studied for several years. Although some tunnels could allow fighter planes to fly, it was basically impossible for a fighter plane to safely enter the tunnel and fly out of the entrance.

He didn't expect that the Tianyi Mercenary Group could do it and directly gave him a sneak attack.

"General, they launched an attack, causing some damage to our fortress."

Lieutenant General Gustavo immediately ordered the relevant troops to attack immediately and destroy the enemy's Gundam troops.

…

More than a dozen Delta fighter jets were equipped with missile bays. They fired countless missiles in one round, destroying some of the fortress' facilities, and the mounted missile bays were removed and discarded.

EX-S transforms into Ms form, and the other machines also transform into Ms form.

In addition to the Elf Cannon, the EX-S also has a beam rifle on its left hand. The Elf Cannon in its right hand fires at a machine facility, destroying the machine and facilities inside.

The other machines also opened fire at their respective targets, and some of the anti-aircraft guns and missile launchers in the fortress were destroyed.

Several underground battleship launch ports in the fortress were opened, and several battleships flew out.

The fortress dispatched numerous Ms and mobile fortresses, rushing towards the position of the Tengu troops.

The Burst Pulse Gundam fired at the Skoriti and other Ms with its beam rifle, and the GMF39 quad-mounted missile launcher fired firefly-guided missiles, hitting several targets.

Some Deltas also use beam guns for medium-range shooting, while others use long-range Mega Particle Beam Rifles for long-range shooting.

"Special Colonel, an enemy warship is coming towards us and is preparing to fire a plasma cannon at us." Pani reported to Li Xiucheng.

"Tell Chen Jianwu to work with us and fire the most powerful weapon to break through the battleship's energy shield and deal a heavy blow."

"receive."

The EX-S, Explosive Pulse Gundam, and Savior Gundam rushed towards the target battleship under the cover of other Deltas.

Although some machines wanted to stop the three Gundams, they were blocked by Delta, and some machines were even shot down by Delta.

The battleship immediately opened its anti-aircraft guns, but was still unable to stop the three Gundams from joining forces.

The EX-S's Spirit Cannon, the Burst Pulse Gundam's high-energy long-range beam cannon, and the Savior Gundam's plasma beam cannon fired at the same time but at different angles.

The battleship's energy shield was directly penetrated by the three Gundams' strongest weapons.

The parts of the battleship that were pierced exploded one after another, and then fell to the ground of the fortress. The violent explosion formed a huge firework ball.

Moreover, the crash and explosion of the battleship also affected and damaged many surrounding facilities.

The pair of "Super Sound" beam cannons of the Savior Gundam directly penetrated the pair of wing birds.

Then, the Savior Gundam landed on the ground and led ten Deltas to other locations to carry out destruction.

In the battle area within the fortress, there were countless destroyed Ms. Dion’s troops and mobile fortresses on the ground.

The Burst Pulse Gundam was using the "Torrent" hyper-speed railgun to injure a Typhon, then pulled out a retractable beam javelin with his right hand and stabbed it directly through the Typhon's cockpit with a long spear.

On the other side, EX-S was fighting with a silver-gray special holy machine. Although the silver-gray holy machine fired a floating cannon, under Li Xiucheng's control, EX-S completely dodged all the attacks of the floating cannon.

Moreover, after being improved by Long Fei, the pair of reflective wired anti-cannon units on the legs of EX-S can reflect the enemy's energy beam weapons.

The silver-gray holy machine also had to dodge the reflected floater beam, and even dodge the EX-S's thigh beam cannon.

The pilot of the silver-gray holy machine suddenly sensed a crisis and immediately dodged to the right, avoiding the terrifying, huge and powerful blue beam.

"Not good." The pilot of the silver-gray holy machine discovered an attack from the left rear and had no time to dodge.

The wired guided cannon on the head of the EX-S hit the back of the silver-gray holy machine directly, destroying the thrusters on the back, and it fell straight down in mid-air, although the thrusters on the legs tried their best to slow down its fall.

EX-S drew out his beam sword and rushed towards the Silver-gray Holy Machine. The cannon behind him fired continuously. The right leg and left hand of the Silver-gray Holy Machine were destroyed by the cannon, and then it was cut in half by EX-S and turned into a ball of fireworks.

A Salamander's shoulder cannon was about to fire at the EX-S, but Li Xiucheng took the initiative and shot directly through the Salamander's cockpit and engine with the beam gun in his left hand.

The shoulder cannons that gathered huge amounts of energy exploded along with the body of the machine. The energy from the shoulder cannons spread all around and even accidentally hit other wingman aircraft.

The 80 Delta pilots are all carefully selected pilots from the special forces. Each of them is an elite among the elites, and their strength is only a step away from being an ace.

The 80 Deltas were divided into several teams, some large and some small, but no matter the size, they could cooperate in the battle seamlessly.
