In the corresponding plan, if a roughly similar battle situation is encountered, the air mecha formation will quickly retreat to the cover of Shenwu City's large array after activating the automatic control under the psychological warfare crisis, and a limited number of stronger hole cards will be activated. Therefore, first of all, the three Divine Thunder Cannons, which had been roughly aimed at their targets underground long ago during the battle, quickly launched their attacks after those mechs were forced to land.

In order to avoid being perceived by the strong, the Divine Thunder Cannon aimed at powerful targets often does not reload shells when aiming. When it was necessary to attack, the shells were temporarily taken from a distance of several tens of meters at the fastest speed, and as soon as they were loaded into the chamber, they immediately began to fire.

In fact, what Zhang Fan doesn't fully know is that the danger posed by this kind of mechanical mechanism, rather than people or demon beasts, is often slightly stronger in terms of anti-perception ability. As a result, the reaction time of the head of the Wican clan when attacked is reduced to one hundredth of a second, and it is almost impossible to make any decent maneuvers.

The Witch King's illusion ability was still strong, and when those Divine Thunder Cannons were aimed at it, it had already deviated by a distance of at least twenty meters or so from its real existence, even if it was close to five kilometers from the front of Shenwu City. In this case, even a nuclear bomb with a yield of two or three hundred thousand tons is not sure to destroy it or severely damage it: this is also a unique ability of a psychic illusion monster beast powerhouse: although the instantaneous mobility is not very strong, the ability to hide his true location is very strong.

However, Zhang Fan and his disciples had already made unimaginable calculations for various possible situations in the Qiankun Shield, and had also consulted a lot of information on a large scale, so they naturally knew that in the face of this sixth-level demon beast powerhouse attacking at a relatively safe distance a few kilometers away, it was very difficult for the Divine Thunder Cannon at the level of hundreds of times the speed of sound that the Zhuji Monk could control to the maximum extent and kill it in an instant, so in this case, it was almost three rounds to form a triangular surface in a state of entrapment for a salvo.

Relying on illusion and the ability to dodge in a short period of time, although the sixth-order witch king also dodged from the center of the incoming cannonball to a distance of about fifteen meters from the nearest projectile, theoretically he could be injured in front of a two or three hundred thousand tons of equivalent lightning nuclear explosion without affecting his combat effectiveness, but in the case of two divine thunder cannonballs, he still fell from the sky after all.

In addition to the overconfident Witch King, the Lightning Dragon Clan, who had been very active in the battle and brought the greatest threat before, was also attacked by the Divine Thunder Cannon shells at the bottom of the box in Shenwu City.

For such a reckless opponent who is not very capable of illusion and mental arts, according to the plan, there is no intention of using three heavyweight Divine Thunder Cannon shells when firing at a distance of three kilometers. At a distance of only about three kilometers from the first line, in the face of the divine thunder artillery shells that attacked at hundreds of times the speed of sound, even at the speed of the lightning dragon, they could only escape from a range of barely about ten meters, because their relatively fragile protection force could not withstand the violent blow after all, falling from the sky, and lost their combat effectiveness in a short time.

And almost at this time, the kinetic energy projectile that was barely loaded with many thunderstorm warheads approached, and from muzzle velocity to power, it was completely incomparable to the previous Divine Thunder Cannon. Obviously, the entire Shenwu City defense system has accurately calculated the use of firepower in many aspects, and if it can solve the opponent with 10,000 tons of equivalent, it will never use 12,000 tons. The reason, of course, is also carefully arranged for a single cluster target whose strength is not too perverted.

Although the battle didn't last long, in a very short period of time, two patriarch-level powerhouses were killed, which still greatly shocked the demon beast cluster that came led by Shadowless.

Faced with the threat of an imperceptible trump card that could emerge from the tunnels or even underground at any time, the entire army had to retreat to a place twenty miles away from the outer defense line of Shenwu City. The fierce and powerful attack came to an end for the time being. Wuying didn't really risk his life for this matter, so he had to retreat.

"It seems that these left-behind forces we have encountered are really a trap for the strong man. If you want to go back, you can go back now. The same goes for those who are willing to stay ... "When Wuying first said this, only a few third- and fourth-order demon beasts who were far from human spiritual intelligence, could not carry out complex thinking, and felt fear, led the remaining first-order demon beasts, which were not much, to retreat.

Many demon beasts at a higher level who can comprehend complex information still feel a little uneasy, and no one can say that this is not some kind of trickery used by that seventh-order ghost powerhouse. Knowing that the Shadowless who sighed took the initiative to drive away a demon beast that seemed to be unwilling to continue fighting, many demon beasts of the fifth or sixth rank led their subordinates to leave one after another, and the remaining forces were basically dominated by the lightning dragon clan and the witch clan who had lost their patriarch.

The contradiction between the Lightning Dragon Clan and Shenwu City is great, and the personality of the clan is also more strong. The tribes of the Wu Clan, even if they usually offend themselves with too many forces, I am afraid that there will be no good results when they lose the sixth-order powerhouse in charge, and they can only seek protection without a shadow.

"Somehow, there was always some uneasiness, and it was obviously not enough for the remaining forces to organize a strong attack. Your task is to scout carefully from the underground, not to move too fast, and to keep an eye out for signs and uneasiness in your mind, understand?" Wuying seemed to have more confidence at this time. However, at this moment, feeling the slightest hint of nothingness, about half a day later, he began to retreat earlier than originally planned.

Having experienced countless risks and crises, even if he does not rely on his own perception, he can judge from experience that even if this kind of action has a chance to succeed, the risks to be taken are obviously not worth the benefits obtained. I've done enough to make a move, and there's no need to continue to take risks.

Zhang Fan had actually just arrived at a distance of about 20 million miles, and soon after that, he began to enter the Qiankun shield and launched his return voyage as quickly as possible. After many battles in the past, Zhang Fan also had a great understanding of the sturdiness and even heat resistance of the Qiankun Shield, and began to make the Qiankun Shield fly at an altitude of thirty-five kilometers at an unprecedented speed before, and soon reached the speed of sound at a thousand times, and started the return journey at ten times the speed before, in the old calendar of almost no more than a day
