High-level summons with different survivability abilities are pouring out from the forefront, and most of the elemental creatures with varying degrees of physical attack immunity behind them cause far more trouble to the earth than the high-level puppets and low-level existences that are oversold throughout the line.

After the firepower was thinned to a greater extent, the skeleton soldiers and demining vehicles that gradually spread up detonated the explosives between the safety zones of the twelve gilded retaining walls, and the traps and barricades were also leveled one by one; Floating mines were also blasted one by one by low-flying creatures......

After the defensive forces were set up little by little in the area where the ground danger had been cleared, the twelve slender extended defensive lines on the side of the Runeterras were gradually connected together, connecting into an outer circle of defense that was only slightly weaker than the inner circle. In terms of area, the circular defense range that rose in series after this wave of impact soared from 113.04 square kilometers to 379.94 square kilometers! That's 3.36 times more than before!

You know, 100 square kilometers is more than the urban area of most small cities on the planet, and 400 square kilometers is more than the size of a large city in the medium and larger cities. In between, Washington, D.C., the capital of the United States, covers an area of only 177 square kilometers!

Such a vast combat area directly leads to the consumption of firepower coverage and the difficulty of precision strikes skyrocketing! And the area that needs to be attacked on the earth side has not only increased by more than three times, but also has to count the boundaries that the enemy who has chosen more to attack can cross from the defensive range to the place where death can cross.

Of course, for the time being, the firepower coverage on the Earth side does not need to be supported by missile bases far from the theater of operations, and it only needs to reduce the rotation time between the current attack clusters to last for a while. The problem of attrition is not a problem, and the purpose of this operation is precisely to exchange ammunition for enemy casualties.

The only thing to worry about is the issue of precision strikes as high-level targets increase and become more dispersed.

In the past, when the enemy's range of motion was small, a covered saturation strike at other times was equivalent to a precision strike, except in certain circumstances. There was not a single cannon dead, and there were still five or six artillery fires around, and then there were still in the same place, and most of them died without deliberately fighting.

But now it can't be counted like that. Covered firepower can only guarantee the destruction of low-level enemy troops, and some high-level ones exist, and it is not small to be able to carry or dodge a few rounds of covered fire. At this time, destroying these few targets with precise repeated strikes is the best or even the only option to prevent them from breaking through and advancing.

Therefore, it is okay to locate the aiming and tracking part by electronic means, and if you can hit it, you will hit it hard, and if you can't hit it, you can't force it. The ones who really felt the great increase in difficulty were the long-range ability and the net bombarders who preferred to rely on their own induction to carry out positioning strikes, as well as a few manually operated artillery weapons such as Fu Shouyuan and others. However, the high-level enemy army, there are still many of them, and they have to rely on the back part to accurately destroy, after all, the ability of these enemies who have been picked out is mainly the targeted dodge of scientific and technological force with higher fire density.

As a result, the more frequent and more mentally concentrated shots have increased the decline in many people's mental and physical fitness, and the earth side must also make new moves.

"Each special ignition team, find the right area to concentrate! 3, 2, 1, launch! ”

Rumble! The sound of the explosion, which I had been accustomed to, was not as shocking as the power of the flames everywhere in an instant, and I saw that 60% of the enemy's defense area was lit up with flames that could barely be extinguished. And the equipment is still human, and if it is stained with Mars, it will all burn to the light!

If you look closely, the fire is ignited from underground, and the first wave of burning is actually the pipes and earth and stones that store and cover up the special fire oil, yes, this fire is so domineering!

What's even more overbearing is the high temperature and lack of oxygen in the entire space caused by the fire! The first time to dodge and raise physical or magical defenses, the follow-up is mostly wiped out on these two points.

About three seconds after the fire started, targeted abilities appeared and began to extinguish the fire by various means.

Two seconds later, the fire was basically under control, but the enemy's equipment, facilities and personnel had been extinguished by nearly half, and it was definitely a wave of large-scale harvesting that satisfied the earth.

During this period, in order to prevent the Earth side from knocking out the remnants of the defense system in one fell swoop, Runeterras urgently activated thirty-two sets of random bomb launch systems, which covered a full 160 square kilometers of airspace in sections with non-stop salvo shots that could no longer be described as huge at a cost, buying time to fill the loopholes in conventional defenses.

In view of this, the Earth side also took advantage of the situation to stop the launch of kinetic weapons and beam energy weapons, and only maintained sufficient pressure with conventional firepower. On the one hand, it is because there is no need to do things that consume energy but do not get the slightest benefit; On the other hand, the energy supply reserve of No. 5 and No. 6 circuits is not much, so if you don't take advantage of this time to adjust, what are you waiting for?

"The kinetic energy weapon and the beam energy weapon have been confirmed to be silent, the No. 5 and No. 6 electric gates are officially closed, and the No. 7 and No. 8 electric gates are opened, and the docking, start-up, and debugging will be carried out immediately."

……

The great movement of the defensive circle did not affect the battle on the front line too much, but the sequelae of the fire to the enemy were already showing up frequently on the front line. Every time a capable high-ranking enemy army stepped on a new ground, they had to dig three feet into the ground to see if there were pipelines to store the oil underneath. If there is, it can be destroyed, and if it can't, it will be marked and wait for the follow-up special person to deal with it. But of course, the earth side will not let them succeed easily, and they want to dig the ground and deal with it, have you asked me if you have shells? Have you asked our ignition team?

With such a deterrent existence, the enemy's rhythm was slightly slowed down. This is one of the reasons why the special oil is not left for further ignition. In addition, due to the timeliness of this powerful fire oil, the last part of the fire oil was filled in the five minutes before the arrival of the war, and the pipeline was cut off and sealed to delay the volatilization of the special part of the medicine.

In the final analysis, it is impossible for anything to achieve absolute invincibility, either because of its own weaknesses or even defects, or because there is an obvious or implicit relationship with other things, which is also the embodiment of the balance rules of the world.

Soon, however, the omnipresent balance was once again in front of the eyes in another form. Swarms of small rats burrow into the ground, wearing collars around their necks that allow them to control their direction and take footage of their sides.

On the other hand, the Earth side awakened some of the ghosts hiding beneath the ground, quickly extinguishing the enemy's attempts to probe the distribution of oil pipes, and also preventing the rats from crashing into the mines after taking pictures. After all of this is done, the wraiths continue to hibernate for the next group of beings intent on demining or something else from underground.

It's just that after the defeat of the rats, the Runeterras did not send out any more underground species. Compared with the necessary investment in building a stronghold on the ground to build a defensive circle, the underground, which is not much different from the ground at first glance, really does not have much of a point of interest worth investing in at the moment. Putting this aside and looking at it again, it's just a wall of fire, and it's obvious which is more important.

Runeland, which has a lot of money but is not used indiscriminately, is almost about to fill in the defense holes on the ground in a big way, so it stops the extremely expensive random bullet firing system that was urgently activated before.

Seeing this, the earth side was laughing but then frowned, and then let go.

After all, it is good to seize the opportunity to increase the consumption of the enemy's resources by more than ten times; The enemy's resources are smashed non-stop, and I have a lot of hole cards, and the psychological pressure brought by the posture of this thing is not ordinarily scary.
