Ye Han asked himself that he didn't have much strategic vision, but he could see the problem clearly, how could the northern capital not see clearly?

Now that the location of West June Fourth has been exposed, even if Ye Han kills this wave of insect swarms, it will only be a matter of time before another wave comes, and there are a lot of insect swarms sent by aliens in this round, but the stamina is not enough, a bit of a tiger and a snake's tail, and eighty percent is not well prepared.

When the aliens attack again, it is not such a small fight, and with the military strength of West June Fourth, the possibility of blocking the swarm is very small.

Anyway, it's not a good idea to stay in West June Fourth, and there are only about 7,000 people left here anyway, and moving all the residents here is the best option.

But Beidu obviously didn't plan to do this, and even the order given to Ye Han didn't forget to eliminate the insect swarm.

If the Northern Capital intends to give up Western June Fourth, how could it give such an order?

Ye Han's ability is limited, so he can only give the dungeon as much help as possible within his ability...... Like plugging that damn hole in the parapet!

Although it was only a matter of time before the aliens dug another passage, it was still of extraordinary significance to block this passage, at least it could buy the dungeon for some more time, and if it was supported by Qingtang, maybe it could arrange some more defenses and turn West June Fourth into a real fortress.

In the current situation of June Fourth in the west, it does not make much sense to change the fortress, and instead of trying to strengthen the parapet, it is better to abandon this place completely and evacuate all the surviving people.

Ye Han didn't know what the above was thinking, but his popular order was to clear the swarm, so he had to find a way to complete the task, but gave some advice to the above.

Moreover, this force is a strategic force of the Space Fleet, and it is impossible to stay in the dungeon for a long time, Ye Han plans to use a few days to clean up the remaining residential areas, and then it is time to order the troops to withdraw from West June Fourth.

Just when Ye Han led the troops to clear out the remnants of the enemy, he suddenly received a new order from Beiyuezhou, asking him to immediately lead the team to block the entrance of the dungeon and not let go of any giant insects!

Looking at the instructions attached to the order, Ye Han quickly understood the situation in the outside world.

Since the Marines blew up the passage, the giant insects in the entire western region have not been very calm, and there are signs of migration in the direction of June Fourth to the west. Not long ago, a new round of rain ushered in the western region, and the giant insects within a radius of more than 100 kilometers suddenly rushed to the west like crazy.

Although the weather is not very good, the satellites in the sky still detect the anomaly of the insect swarm in time, and West 64 is not far from Qingtang, and there are many mercenaries scattered in the wasteland between the two places who rely on Qingtang to make a living.

After receiving a large number of similar reports in a short period of time, Qingtang immediately attracted great attention to it, and after summarizing the news reported from all over the country, Qingtang immediately found that the target of the giant insect was West June Fourth.

In this way, it will be easy to do, although the bad weather will continue for a while, but the bad weather will not affect the garrison to kill insects.

The Qingtang Command immediately issued a sniper order, raising the mercenary's reward for hunting giant insects by one percent.

At the same time, Qingtang also issued a ban to the mercenaries, dividing West June Fourth and some surrounding areas into dangerous zones, strictly prohibiting anyone from entering, and those who cross the border will bear the consequences.

On the other hand, Qingtang submitted an operational plan to the northern capital as soon as possible, planning to shell the swarm at an appropriate time.

As the largest settlement area in the entire western region, Qingtang has a perfect defense system, all kinds of artillery groups in the far, middle and near, shelling a group of giant insects is not a matter at all, there is no need to alarm the northern capital of this scale of battle, the reason why it is reported to the northern capital is just to archive for future reference.

Soon after, everything was ready, and Qingtang released drones to monitor the situation of the swarm and guide the direction of the shelling swarm.

A few hours later, the first giant insects broke into the restricted area, but the insects were relatively scattered and had no value for fire coverage, and they had to wait for the insects to gather before the shells that could be used to hit them.

But the aliens have long learned to be obedient in the war with humans, and they know that the firepower of humans is not easy to provoke, so they deliberately disperse the swarm, which is very similar to the straggler line of humans, and I don't know if the aliens came up with it themselves, or heard it from the modified insects.

All in all, the biters won't assemble at all until they reach the entrance to the dungeon!

It was for this reason that Ye Han received an order from Beiyuezhou.

There wasn't a lot of time left for Ye Han, so he immediately led the team back to the core area, brought all the ammunition in reserve, and then hurried to the exit of the dungeon.

This is not counting, because he felt that there was not much ammunition in his hand, Ye Han took advantage of the fact that the insect swarm still had some time to arrive, and seized the time to issue an airdrop order to the Ningwuguan, asking the battleship to airdrop a batch of weapons and equipment.

A few minutes later, the heavy equipment requested by Ye Han landed, and the soldiers swarmed up against the drizzle, opened the drop box on the spot, and carried their respective weapons with them.

These include 12.7mm three-barreled heavy machine guns, light laser cannons with knapsack batteries, 20mm remote-controlled snipers with special ammunition, individual rocket launchers, and ample ammunition, to name a few.

The cold weapon that had just been designed and finalized was also airdropped together, and Ye Han took it in his hand and looked at it, almost vomiting blood on the spot - isn't this just a throwing stick?

This thing is indeed based on the slinger as the prototype and thickened, but the length and feel after throwing it off are good, the weight is greater than the steel bar, such a small volume and such a heavy weight, obviously also used some kind of special material.

The soldiers were armed as fast as they could, a few dragged the drop boxes back the same way, and the others retreated and planted mines, using hundreds of mines to prepare a welcome gift for the swarm.

The drop box dragged back to the passage was not wasted, this thing is also multi-purpose, after being disassembled and put back together, it is a simple bunker, and the thermal weapon against humans may not be useful, and it is enough to block the swarm.

Everything was ready, and after more than twenty minutes, the first giant worm appeared in the warriors' field of vision.

The drone in the air used the camera to penetrate the rain curtain - it was a small group of jumping insects, no more than twenty, and the distance between the insects was particularly wide.

Such a target is not suitable for fire coverage, but Ye Han did not intend to give the insects time to assemble, and immediately gave an order to the sniper.

The sniper had already set up the sniper gun on the top of the mountain, and immediately after receiving the order, he manipulated the sniper gun to aim at the swarm, and with a muffled sound, the 20-millimeter caliber shell flew over two kilometers in an instant, and the cannon doubled out, penetrating two jumping insects in a row, thus opening the prelude to the battle.
