Liu Huaidong’s idea is to play along. Aliens like to delay, so let them drag it. Anyway, the port is not dangerous

But just in case Liu Huaidong drew a line in the minefield and ordered the artillery to shell his mother as soon as the swarm crossed the line.
This line is located at one-third of the minefield side, which means that the artillery will be on fire when they flatten two-thirds of the minefield.
The remaining one-third can’t stop the swarm, but it’s still no problem to stall the swarm. It’s definitely not good to land the swarm with a minefield before the time.
It would be better if the class-coordinated warships could arrive before the swarm crossed the line, and then it would be economical and affordable to directly cover the swarm with laser to save precious shells.
The garrison is also equipped with a number of laser weapons, but these expensive equipment are arranged in the base instead of in Xidan Port.
Forty-seven minutes after the battle, the swarm stepped through the minefield, and the coordinated warships still did not arrive at the base. Sure enough, the artillery shells covered the swarm instantly.
Chapter 151 At all costs (2)
More than 100 artillery guns of various calibers fired Xu Jin barrage and pushed to the coast step by step from the actual line on the map.
The density of the shell is not high, but it can’t stand the power of the shell. The radius of the shell to kill the insect is 22 meters, which ensures the killing effect. The distance between the impact points of the shell is about 30 meters.
Wheeled assault guns have a caliber of over 100, so it’s better to force howitzers. That’s the way it is-it’s better to force howitzers because the barrel has a long range and can hit close-range insects far away.
The real main force is the 155 mm self-propelled howitzer, which is specially developed for giant worms. It has specially increased its power to kill insects with a radius of 67 meters. The power of a shot covers more than half of the football field. Any giant worm in this range can’t escape and die, but it is also seriously injured.
No matter how big the minefield is, it can’t stand the artillery bombardment. Ten 155 howitzers can cover two minefields in one volley.
If the artillery didn’t know how to control the falling shells, they would have destroyed the minefield where the insects had not stepped.
In just half a minute, the shelling destroyed the two wings of Xidan Port. Just after the shelling, the base fired several mine-laying rockets into the minefield. Countless mines fell from the sky to the minefield full of insect corpses.
After landing, one mine will automatically turn over to support the mine and enter the working state.
Some giant worms that are not dead twitch their legs consciously, but they happen to be within the detection range of mines. These small movements immediately detonate the mines.
The number of mine-laying rockets is limited, and the density of newly laid mines is not as high as before, but it is better than nothing.
But the aliens didn’t stop at all, and new swarms flooded the coast.
Liu Huai-dong’s whole person is not well. How come there are so many bugs when there are not 10 thousand and thousands of giant bugs lost by stepping on thunder and shelling aliens?
No matter how strong alien biotechnology is, worms can’t come out by themselves?
If you can’t figure it out, you can’t figure it out. Now that the worm has landed, you must bomb his mother.
This time, Liu Huaidong didn’t draw any dividing line, and directly ordered the artillery to find their own time. The original dense guns became sparse, but every time they hit, a large number of giant worms were killed and injured.
In this way, the defenders and the swarms fought for more than two hours, but the swarms failed to attack Xidan Port, which made Liu Huaidong very satisfied.
Two hours later, the battleship arrived at the laser cannon and killed more than half of the landing swarm in one volley, completely smashing the alien plan, and the aliens had to stop attacking.
There were warships to cover the aliens. There was no movement for two days until the third night when the base changed suddenly. Dark clouds covered the day. The aliens took the opportunity to show the third round of attack, and the first hand was a swarm of insects, worms and servants.
Although the defenders have been strengthening their defenses, I still didn’t expect that the aliens were determined to make such a big move, which was that the servants and soldiers were in groups and hit the defenders off guard.
The defenders of the retaining wall fired back at the first time, but the enemy’s offensive went far beyond it. In just over ten seconds, the swarm of servants led the soldiers to break through the retaining wall and burn the war to Xidan Port.
For flying footmen, more than ten seconds is enough for them to fly over the retaining wall.
When the soldiers rushed out of the barracks, many sections of the retaining wall had been broken by the swarm of insects and the sections in the hands of the defenders were also in jeopardy. At the critical moment, Xiang Dong made a decisive decision and ordered the troops to retreat to the ground and rely on solid bunkers to continue fighting.
He really wants to withdraw the wall soldiers, but the enemy is not allowed at the time and it is impossible to give him this chance.
