Under the combined control of the electromagnetic powers, the specially made metal formed an impregnable steel barrier hundreds of meters wide and thirty meters high.

On top of this barrier, the howling and gapless hurricanes combine with the compressed water to form a second line of defense beyond the steel barriers.

But it was much more than that, in the space that was closely attached to the second line of defense, a piece of iron sand formed a third, also a black shield that was directly exposed to the death zone.

Such a high-density multiple defense is divided into three routes, leaving behind the ability to maintain the passage along the way while advancing, so it can become a coalition army of 500,000 troops divided into three routes, penetrating into the 'perfect shield' of the death zone of the 'Holy Grace' city territory, guiding the rear army to the depths of the 'Holy Grace' city territory at a speed of 60 kilometers per hour, like a bamboo, advancing unhindered.

Above these three non-stop advancing passages, the air force flight formation with the core of the 'Mist' is flying and advancing at the same speed as the troops, and the fire control system of both the Apache combat helicopter and bomber formations is already ready to go, and the fire control system of the 'Mist' is comparable to 80% of the firepower of the coalition's total flight formation, and it is always scanning everything near the three advance channels, just like a vulture in the desert trying its best to find its own food.

It was useless for the coalition forces to resist such overwhelming bamboos and illusion curtains, and the troops of the 'Watch' Federation, under the wrath of the mad President Farris, began to quickly assemble and attack the left and right flanks of each advance channel in six directions, with a clear purpose, that is, to directly cut off the advance channel from both sides!

"Stealth unmanned reconnaissance aircraft detected the approach of enemy units before they were shot down, and about 1,000 of the strength of the force were about 1,000 medium tanks with strong mobility, 20% of about 400 were fanatical self-detonations, and 10% were logistics supply convoys of medium tank units. 20% of about 400 are anti-aircraft mobile artillery. ”

Hearing the report of the enemy's strength coming back from the bridge, Wu Fei, who was wearing the mighty black armor, did not panic at all, after all, this was also expected.

"The flying formation was divided into six interception units consisting of ten Apache combat helicopters to intercept the enemy before it approached the advance lane, and the main targets were fanatical self-detonators, and the bomber flying formation bombed the enemy medium tank units after they had advanced to within 10 kilometers of the advance channel. The Mobility Mobile Unit will start from the Mist with a team of fifteen people to conduct a lightning operation when the enemy Adept and Core Interceptor appear, and be sure to completely destroy the enemy Adept and Core Interceptor 3 kilometers before they get close to the advance channel! Wu Fei's orders were issued one by one, and the entire coalition air force unit was fully operational, and began to carry out the task of escorting the First Army of the Army.

In the following minute, a dense burst of explosions and artillery fire could be heard directly in front of the advance channel, which was the deafening sound of an interception force composed of Apache combat helicopters exchanging fire with the enemy, and according to reports from the front, the interception force sent by the 'Watch' Federation this time was very stubborn. It also sent a first-of-its-kind self-detonation vehicle designed for fanatical self-detonation vehicles, each of which carried 5 fanatical self-detonators like a drill, which was not only extremely fast but also extremely strong in external armor, which caused great trouble for the Apache interceptor force, and the anti-aircraft mobile artillery sent by the 'Watch' Federation was also equipped with a more accurate and lethal fire system, so that the Apache interceptor force could not accurately and effectively hit the self-detonation assault vehicle ridden by the enemy's fanatical self-destructors.

"The plan was changed to send a flying formation of fifty bombers, covered by four Apache helicopter gunships of ten in one. Intensive bombardment was carried out close to the route of the self-detonating assault vehicle, and the Apache interceptor force responsible for interception was withdrawn from the front line. "Wu Fei changed his deployment in response to the new vehicles that had appeared in the enemy.

After Wu Fei's order was given. The Apache interceptors on the front line quickly retreated, while the bomber formations, which had been in good gear, accelerated in an attempt to blow the self-detonator to pieces before they approached.

After the flight formation of 50 bombers broke away from the coalition air force formation, four Apache helicopter gunships also advanced with them around the bomber formation.

"Report to the Emperor, the ground troops advancing the passage encountered an attack by nanobots, and the advance speed dropped by 30%" When a dense explosion was heard in the distance, a series of flames burst into the sky. A notification from the bridge made Wu Fei's brows furrow slightly, the 30% speed drop was indeed a bit unexpected compared to the planned speed drop of less than 15%.

But Wu Fei did not mess up even a little bit because of this, but looked at the holographic projection screen shared with the ground troops.

On the ground, a thick black fog raged around the three advance paths, and it contained pervasiveness. The number of nanobots that can wreak havoc on both organism and mech, and the tsunami-like black fog that covers the sky shows how terrifying the number of nanobots is that is almost invisible to the naked eye, and it can even be said that everything that passes through them is reduced to a residue smaller than grit.

However, the triple defense at the head of the three advance passages made the black fog helplessly corroded and advanced on the outside, and could not break out into the terror that should have been raging.

After a brief exchange with Wu Fei, Lin You ordered all the arms to move to the area adjacent to the periphery of the passage, and counterattacked the seemingly ubiquitous black fog with a pillar of fire, so as to weaken the black fog's obstruction to the advancing troops, and then restore the advance speed as much as possible.

After just three minutes, the advance passage was like a raging steel dragon, almost seamlessly gushing out deadly dragon breath, and this magical flame is the best means to deal with this kind of large area, with a terrifying number of small enemies, although this pillar of fire covered form of attack, its attack power will be weakened a lot, but it ensures an absolutely large area of attack, and even if the attack power is weakened a lot, but it is not the weak nanobot can resist.

Soon, the speed of the advancing force was restored to an acceptable range of only 13 per cent, but the enemy interceptor force was already approaching the effective firing range.

When a black line appeared at the end of his line of sight with the thick smoke billowing behind him, Wu Fei immediately ordered the entire coalition air force formation to set off and start intensive bombardment five kilometers in front of the advancing troops.

With five bombers as a triangle, the number of nearly five hundred, the bomber group that came like an overwhelming dark cloud was advancing at full speed. The 1,000 medium tanks of the Watch' Federal Interception Force began to divide into three waves of steel and rushed upwards as they advanced, forming a long line and falling down in the sky, and when they touched the ground, the earth turned into an endless sea of fire in the blink of an eye, and the mushroom clouds that rose up in the array of 1,000 medium tanks in a line tore apart the metal shells that gave people a great sense of security, and also took away the shouts inside: "For the Holy Lord!" "The life of a soldier.

Half of the interception force composed of 1,000 medium tanks was destroyed in an instant, but even if it was blown up and could not move, each tank would still start the final charge procedure, and launch a final suicidal charge against the coalition advancing troops with a tail thruster with only one chance, and the triangle impact angle in front of each tank lit up with the brilliance of particles, which was the product of the crystallization of human top science and technology, and it was also a milestone technology that instinctively pushed mankind into the era of the great universe, but it was used to deal with its own kind.

As expected, in addition to the 400 medium tanks that launched a suicidal charge due to the loss of combat capability, the coalition advancing troops were forcibly stopped, and the remaining 600 medium tanks activated the particle defense shield when the coalition bomber formation arrived overhead, and used this to resist the intensive bombing of the coalition bomber formation, and then successfully broke through to two kilometers away from the coalition advance force, and also entered the optimal range.

The guns of a medium tank poured shells on the cannon in a continuous flash of light and deafening explosions of nearly fifty centimeters from the muzzle, and the most solid ability triple shield of the first part of the coalition advance force was poured on top of the most solid ability triple shield of the coalition advance force, and the explosion of fire instantly enveloped the triple shield, but it was unable to break through the powerful 'perfect shield' supported by a large number of ability people for a while.

In response to this, when Wu Fei gave an order, the 'Mist' first dropped out twenty landing craft full of elite supernatural supernatural personnel, and even when the landing craft broke through the rain of bullets in the fierce exchange of fire, and the guns fired in unison to drop the supernatural beings on the battlefield, the fire control system of the 'Mist' also began to operate at 90% power.
