In the next period of time, in addition to taking the team members out on missions, Ye Han's most important job every day is to pay attention to the battlefield situation.

In order to cooperate with the plan of the allies, the defenders of Funing did not plan the gains and losses on the first floor and one street, and the battles that occurred every day revolved around how to annihilate the living forces of the swarm, and they always took the initiative to withdraw from the position after giving the swarm a certain degree of damage.

Within a few days, most of the outer layers of Funing City fell into the hands of the enemy.

In the game of Go, there is a saying that the corners and edges look inconspicuous, but they can occupy more of the plate.

Most of the outer layer fell into the hands of the insect swarm, that is, close to one-fifth of the land of Funing, and the insect swarm had the meaning of completely surrounding Funing and surrounding the defending legions.

Although the defenders lost a large number of fortress buildings, there were not many casualties, and the defenders were more concentrated after withdrawing from the perimeter, like a withdrawn fist, which could be hit hard at any time.

The bugs didn't feel it, but the bugmen who commanded the swarm found that when the war first began, it didn't take long to capture a fortress building, and it didn't consume many bugs.

But now it's different, and it takes three to five times more time and cost to capture a fortress building than it used to be!

And as the area occupied by the insect swarm is getting larger and larger, the distribution range of the insect swarm is also getting wider and wider, although the reinforcements are constantly going to Funing, but the number of reinforcements is limited, and it can barely make up for the loss of the battle.

The density of the insect swarm is too low, which directly leads to the lack of defense in the occupied area, and the defenders will find a weak link in the insect occupied area to tear a gap if they have nothing to do, and take the initiative to attack to find trouble with the insect swarm.

This is not only done by the defenders, but also by the special service team, which has caused a lot of anxiety to the insects who command the swarm.

There is no way, the military has never believed in rigid defense, and Yuan Yuan is a diehard loyalist of active defense, and the swarm has not entered the city, and there is no environment for active defense. Now that the swarm has entered the city in large numbers, the entire defense line is full of holes, and no matter where the opening is made, the defenders' counterattack will give the swarm a headache for half a day.

The key is that the purpose of the defenders' counteroffensive is not to advance the battle line, but to stare at the insects to beat them to death, and every time they fight fast and slowly, without waiting for the insects to send reinforcements, the defenders who attacked have taken the initiative to withdraw, even if all the insects on the defense line are dead, they will not move the battle line out.

At this point, the battle has entered a stalemate phase, and if the swarm does not get stronger support, it will be good to be able to control the current occupied area.

But the alien's order to the insect man was to continue attacking!

Reason tells the Zerg that the consequence of continuing the attack is likely to be a total collapse, but in the Zermin's mind, sanity must give way to the aliens' orders, and the result is that the Bug Swarm has to continue to attack with insufficient troops, and continue to suffer huge casualties that should not have been suffered.

The defenders' tactics are nothing new, but it is very effective against the swarm, and the current attack of the swarm can be seen as the final struggle, and it is only a matter of time before it collapses.

Compared with the situation in Funing City, Ye Han was more concerned about the battle situation outside Funing City.

The aliens did have the intention of encircling the point to send reinforcements, and while sending a large number of giant insects to attack the city, they also arranged for the same number of giant insects to intercept human reinforcements.

The battle for reinforcements was first fought in Europe...... The swarm has the best foundation there, and there are many of them, and with the fact that Europe has a well-established transportation network, humans are very fast in supporting various cities, so the confrontation is the earliest.

Mi and Funing are not slow, and they are an hour later than Europe.

However, it was different on Ah San's side, where the infrastructure was weak and the army's mobility was low, and it was a day later than in other directions, and the reinforcements only exchanged fire with the insect swarm.

Ye Han didn't know much about the situation abroad, only that the reinforcements and the insect swarm were fighting fiercely outside a few cities, and both sides had their own victories and defeats.

The situation in Funing is more complicated, not only the insect swarm intercepts the human reinforcements, but the military also organizes troops to attack and intercept the insect swarm, and the two sides take Funing as the center and fight wits and strength within a radius of more than 100 kilometers.

The most common situation is that the military sends reinforcements in a similar way, advancing in the direction of Funing at a very fast speed, constantly avoiding and intercepting the insect swarm on the way, interspersed between the insect swarms at high speed...... No matter how you look at it, the mission of this force is to support Funing at any cost.

But in reality? The seemingly fully staffed troops are actually just good-looking empty shells, and in fact there are not many troops.

And that's not all, there is a real combat unit behind this unit, which is specifically responsible for dealing with the swarm of interception, and this force is more mobile and combat-ready, including both armored units and motorized infantry.

In addition to frontal combat units, the military also mobilized a large number of long-range artillery fire, as long as the insect swarm appeared, not to mention the first artillery fire covering, and then the armored units and motorized infantry coordinated to clean the battlefield over and over again.

There is not one in ten bugs that can survive this three-dimensional offensive, and it is often the swarm that is dispersed by the anti-interception human forces before the interception begins.

Even after suffering a few losses, the insect swarm also learned to behave, the bait did not enter the encirclement and resolutely did not take the lead, and learned the military's methods to the fullest, arranged anti-interception insect swarm in addition to intercepting the insect swarm, and once the human anti-interception force appeared, it immediately launched an attack, and did its best to fight the human race.

Originally, it was just a decoy and interception troops, but within a few days, it was increased layer by layer, and a bait had to arrange three or four troops to effectively clear the interception swarm.

In the most serious interception battle, after the decoy was attacked by the swarm, the military put in seven waves of reinforcements in half an hour, not counting the long-range artillery fire that supported the battlefield from time to time, and finally relied on the advantage of firepower to defeat the swarm, which achieved the final victory.

However, no matter how well the reinforcements fight, they must consider the overall situation, and they scattered and intercepted the swarm several times, but the reinforcements just did not get close to Funing, and always looked for fighters on the periphery of Funing.

Their task is the same as that of the Funing defenders, which is to eliminate the living force of the swarm as much as possible, and entering Funing is equivalent to actively wearing shackles, which no sane commander will do.

It's February in a blink of an eye, and more than ten days have passed, and the battle situation is still stalemate, perhaps because the progress in all directions is not very smooth, and the swarm is in the middle again. A new offensive was launched in the eastern region.

Ye Han didn't know what to say when he heard the news, that place was full of deserts, and it was one of the most unsuitable areas for the survival of insect swarms, what was there to worry about for aliens?

Petroleum?

No kidding, although oil is organic, can aliens turn oil directly into bugs?
