"All fighters, prepare to drop bombs as planned."

In the rear, in military bases near the city, dozens of large bombers and hundreds of light bombers were preparing for bombing missions.

The heavy bombers carried 30 tons of ammunition, and the light bombers carried 7 or 8 tons of ammunition.

The bombing order came, the pilots were ready, and they flew into the sky in teams one after another.

"The bombers have departed and will arrive in about five minutes. Let's prepare for ground guidance."

They still have a lot to do before the bombing troops arrive.

They had to guide the air forces to the correct bombing area, which was not difficult. They just had to arrange the equipment and place the smoke bombs of the correct color.

Three minutes later, the ground forces were ready.

The command center also sent a message that the bombers would arrive on time, asking them to fire red smoke bombs at the bombing area thirty seconds before the bombers arrived and activate the guidance equipment at the same time.

Several people took out their watches and started counting down.

When the bomber came into view, the countdown began. When it came to the last thirty seconds, the officer immediately gave the order to launch the prepared smoke bombs and start various instruments at the same time.

The bomber was thousands of meters in the air, and as the last second countdown fell, the bomber began to drop the bomb.

Each bomb fell accurately within the guidance range. However, the bombs did not explode as expected when they landed, but instead drilled deeper.

The first batch of bombs were not ordinary bombs, but bunker busters.

This is a bomb specially developed to attack underground targets, code-named BC-03. It is a special bunker-buster that can penetrate 60-meter-thick concrete fortifications.

The bomber will launch five rounds of bunker-buster bombs to ensure that the following bombs can enter the underground space.

Lu Chengchuan didn't know how deep the underground palace was, he just hoped that the bomb could hit the target and let the Corpse Demon King have a good meal.

"Attention, round two is coming."

Zhou Yaning's cold voice sounded in her ears. After she finished speaking, the bomber that had flown past turned back.

The second round of bombing began, and there was still no explosion. Five rounds were dropped, and Lu Chengchuan kept watching. The real main course was coming next.

Soon, the bombers turned back and began dropping heavy bombs.

Shells rained down on the ground, and a large number of shells hit the ground, followed by explosions and flames.

But compared with the number of bombs dropped, there were not many explosions, and more bombs were dropped accurately into the ground.

The bombers went back and forth for several rounds of bombing. After they dropped all their bombs, they prepared to return and wait for feedback from the ground forces whether they decided to start the second round of bombing missions.

The bomber had just returned when everyone's feet suddenly began to tremble.

"The bombing zone has collapsed! Don't get close!"

They are in the desert, with bunker busters and bombs, so ground collapse is expected, but it is very abnormal that it collapsed only now.

"Everyone retreat, the armored forces go first!"

The ground shook even more violently. Seeing that the cracks were about to spread to the front, the commander did not dare to take the risk and could only order his soldiers and tanks to evacuate.

This is simply a disaster, and it is a disaster that they created.

"Captain Lin! Captain Zhou! Let's leave too!"

After giving the order, the commander found a few people and persuaded them to leave together.

Lin Jing and Zhou Yaning looked at Lu Chengchuan. He didn't say anything, and they were both unsure. Lu Chengchuan looked ahead, where cracks appeared and gravel was pouring into them.

"You guys go first, I'll take a look here."

Everyone believed Lu Chengchuan, and when they saw the cracks spreading, they hurriedly left with the army.

The cracks widened, sand poured in, and wisps of black gas seeped out from under the gravel. Lu Chengchuan could see it clearly.

He wanted to go over and take a look, but the crack quickly spread to his feet.

As a last resort, Lu Chengchuan could only walk to the side and use the shrinking technique to reach a place where there were no cracks for the time being. However, the cracks became more and more, and Lu Chengchuan could only run backwards away from the bombing area.

As the cracks increased, the bombing area began to collapse.

A huge pit with a diameter of hundreds of meters appeared, and now there was no idea what was underneath.

After the ground stopped shaking and the sand stopped flowing out, he was sure everything was fine. He then slowly walked to the edge of the pit to check. But there was nothing here except sand and charred rubble, no monsters, and no entrance to the underground palace.

"The Corpse Demon King really won't come out."

Even though it was blown up like this, the Corpse Demon King didn't come out. Did he run into that door and hide?

Lu Chengchuan just felt it was a pity. If he killed the Corpse Demon King, how much life would he gain? If it weren't for the help of the black air in the underground palace, the Corpse Demon King would have been chopped to death by him long ago.

"Zizi ...

The communicator made a buzzing sound, and then Huang Hengyong's voice came from inside. Lu Chengchuan picked up the communicator.

"I can hear you."

"Mr. Lu, what's going on now? Should we start a second round of bombing?"

After getting in touch, Huang Hengyong quickly asked him whether he wanted to continue the bombing. The bombing area was still filled with smoke and dust, and the drone could not see what was going on inside.

"Not for now. The bombing zone has collapsed. There's nothing left."

The bombing area collapsed and was filled with sand. Dropping bombs again would not be effective and might even cause a second collapse.

"If possible, send some engineering teams to dig out what's underneath."

Now he only wanted to know whether the Corpse Demon King was dead or not, whether the underground palace below was intact, and what was behind the metal door.

Lu Chengchuan was very curious, but he alone could not dig this huge pit that was hundreds of meters wide and unknown depth.

"Okay, we'll send a reconnaissance team over there right away to see if construction is possible."

The smoke and dust slowly dissipated, and not long after, a team wearing protective clothing arrived here. Following the positioning of the communicator, they found Lu Chengchuan.

"How is it, can we start construction?"

After both sides confirmed their identities, Lu Chengchuan pointed at the big pit in front and asked.

The construction team leader looked around and shook his head repeatedly: "The view is too blurry, we can't see the specific situation of the site clearly. We have to wait for the smoke and dust to dissipate before we can investigate!"

The construction workers could not see the specific situation of the pit and could not draw any conclusions.

Since they had to wait, Lu Chengchuan took them outside. It was not until around six o'clock in the evening when the smoke and dust finally cleared that the members of the construction team returned to the vicinity of the pit.

The construction team members set up various instruments and began busy work. At night, they set up bright headlights to continue working, while Lu Chengchuan waited for the results in the back.

"Sir, the results are in."

After a night of measuring and calculating, the construction team leader came to him with the results.

"Can we dig it?"

Regardless of anything else, Lu Chengchuan is most concerned about this issue.

"Okay, I'll ask my superiors to mobilize the equipment later. However, the workload is too large, so it will take at least a month to dig it out."
