At the same time as the first regiment was fighting fiercely with the enemy, Ye Han received a report from the third regiment, and the enemy was found in the other main caves one after another, and even contact had occurred, and there were already mines and explosives in the two passages, but the demoman miscalculated the solidity of the tunnel, and the explosives package was a little smaller and failed to blow up the tunnel, and the enemy was marching towards the shaft from all directions and at all levels.

Long Jianguo realized that the situation was not good, and sent all the troops of the three regiments to block the tunnel, and was making every effort to block the enemy army, temporarily curbing the momentum of the enemy's attack, but it is really difficult to say how long it can hold out.

The situation suddenly took a sharp turn for the worse, and if the enemy broke through the blockade, it would not be long before the entire shaft could be occupied, and then not only one or three regiments would be blocked by the enemy, following in the footsteps of the multinational forces.

At that time, the possibility of the army escaping will be infinitely close to zero, and there will be no human land force to be found near Ganymede, and if it is surrounded and there are no reinforcements, the result of waiting for this force will inevitably be the total annihilation.

Only if the strong man breaks his wrist, leaves some people to continue to block, and the large army withdraws immediately, can the whole army be avoided, but the operation has just begun, is it appropriate to withdraw the troops at this time?

Ye Han struggled violently in his heart, and at this time, he suddenly received a communication from Bian Ge: "No. 1, emergency, the enemy has attacked!" ”

"What?" Ye Han couldn't believe his ears, "What's the matter?" Where did they get in? ”

"In the middle of the ship!" While speaking, Bian Ge sent the three-dimensional structure diagram of the wreckage of the giant ship to Ye Han.

Ye Han looked at it and immediately understood the situation.

The place where the enemy attacked was in the middle of the wreckage of the giant ship, where there was supposed to be a hatch leading to the outside of the ship, and the hatch was close to the wall of the well, which was no problem, but there happened to be a passage in the wall of the nearby well.

The passage is close to the giant ship, and the distance between the two is not as thick as a palm, so there is no problem, but the problem is that the enemy has expanded the exit of the passage, and he has dug the exit out of the hatch, played a secret crossing, and quietly opened the hatch and rushed in.

The area near the hatch has now been marked with a flashing blue to indicate that the area has been taken by the enemy, and outside the blue zone is red to represent your own power.

Ye Han immediately asked, "What's the situation?" ”

"The enemy has been trapped near the hatch and is being surrounded with all its might." Bian Ge said.

Ye Han reminded: "You can't relax in other directions, if the enemy can come out of this place, you can attack from other directions!" ”

"I don't have that many people!"

"I'll give you the reconnaissance battalion and the teaching battalion again, be sure to defend the giant ship!"

"Yes, people are on the ship!"

"Get out, I don't need you to work hard, I want you to hold this retreat!"

"Yes, at any cost, hold the retreat!"

After handing over the reconnaissance battalion and the teaching battalion to the second battalion temporarily, only the guard battalion commanded by Luo Qi was left by Ye Han's side.

The situation was already very dangerous, Ye Han didn't dare to hesitate any longer, gritted his teeth and made up his mind, and was about to order the first and third regiments to withdraw, when he suddenly heard Luo Qi's anxious voice again: "Division commander, there is a situation!" ”

Ye Han's head was big: "What's the situation?" ”

"There is a situation at the bottom of the well...... It's aliens, they're at the bottom of the well! ”

Ye Han immediately connected to the image sent back by the mechanical spider, and the bottom of the shaft connecting the airport appeared on the screen, and hundreds of aliens were climbing up the rock wall, like a group of evil spirits crawling out of hell, and there were countless enemies in the air port under the shaft.

The No. 1 passage is on the lower level of the shaft, and the enemy only needs to climb up a little more to block the back road of the first group, Ye Han's heart slammed into it: "One regiment at a time, all the troops will go to the hole immediately, and they must keep a safe distance of five hundred meters from the shaft no matter what; Three regiments, three regiments, your troops must ensure three hundred meters, hurry up! ”

Receiving this order, which has no beginning or end, everyone was stunned for a moment, and then they all remembered something, and immediately ordered the troops to advance, at any cost.

Xiao Yuan led a group to rush into the main hole of the No. 1 passage and launched an attack on the curve without hesitation; At the same time, some units of the third regiment also had to charge the enemy, exchanging blood and lives for valuable space.

After the order was issued, Ye Han turned around and looked at Luo Qi: "Individual missile, one shot!" ”

Luo Qi instantly realized: "What about nuclear missiles?" Bring me one! ”

Immediately, a soldier handed over a single bazooka, its launch tube was much thinner than an ordinary bazooka, and at the front was a super-caliber warhead similar to a 40 fire, and the side of the warhead was also painted with a light yellow symbol of ionizing radiation.

After Luo Qi got the individual missile, he carried it on his shoulder, and his upper body leaned out of the hatch slightly, and immediately pulled down the trigger after aiming at the bottom of the well.

With a soft sound, the booster rocket pushed the 12-ton miniature nuclear bomb to the bottom of the well, and Ye Han and Luo Qi left the hatch at the same time and hid inside the ship.

A few seconds later, the bottom of the well suddenly burst out of a bright light that could not be seen directly, and the nuclear explosion with an equivalent of 12 tons instantly destroyed the enemy troops assembled at the bottom of the well, and the explosion not only destroyed the airport, but also produced a strong shock, and many enemies who climbed on the rock wall were shaken off by the explosion and fell into the crater left by the nuclear explosion.

At this time, standing by the hatch and looking down, a huge crater had been blown out at the bottom of the well, and the bottom of the pit was melted by the high temperature of the nuclear explosion, turning into a fiery high-temperature purgatory.

However, in addition to the vibration, the high temperature generated by the explosion did not affect the shaft at all, and Ye Han immediately realized that he had underestimated the area of the airport.

There is no air here, and the power range of a 12-ton nuclear explosion is a few hundred meters, so there is no shaft...... It is true that the power of miniature nuclear bombs is far inferior to that of ordinary models.

But then again, if it weren't for this low-yield small nuclear bomb, how could Ye Han dare to use a nuclear bomb in a narrow channel? It's not such a way to die.

"Haha!" Ye Han couldn't help laughing, "Luo Qi, call two people to come over and watch, if the enemy dares to take the lead, he will fight me, Lao Tzu has a nuclear bomb!" "I knew that the airport was so big, what did he do to let the troops withdraw? Just smash the nuclear bomb down!

With this method, only a few people are needed to hold the shaft, and the rest can be strengthened in other directions, indirectly increasing their own strength.

"Yes!" Luo Qi was also beaming with joy, the missile just now was fired by him himself, and at least thousands of enemy troops were killed with one shot, maybe even the giant ship below suffered.

Infantry fights giant ships, this kind of good thing of hitting big luck is not something that anyone can encounter.

At this time, Ye Han suddenly heard a heavy muffled sound, and his body fell uncontrollably.

Not only Ye Han, but the soldiers in the bilge were all staggering, because the gravity here was particularly low, and the movements of the soldiers falling were also surprisingly slow, and after the shaking stopped, most of them were still floating in the air.
