If the cannon fodder that approached first was a Jindan Yuanying level master with a strong perception as Zhang Fan had encountered at the beginning, this kind of divine thunder arrow shot from ten kilometers away would not pose any threat even if it was a cluster, and it would be easily dodged. That is only a ton of modern explosives equivalent warheads, or a powerful impact force similar to kinetic energy, which does not pose much of a threat.

But for those first-order demon beasts who came to test the defense system around the first order, the effectiveness of the Divine Thunder Arrow seemed to be completely different. Although the arrows are speeding from a distance of ten kilometers, they are often found at three to five kilometers when the Divine Thunder Arrows are about the same size as ordinary arrows, and some extremely fast Divine Blades and Lightning Dragons can only dodge a distance of about ten meters in one twentieth of a second, but at best, they can only barely be injured in the face of a near-explosion explosion of a Divine Thunder Arrow with an explosive power of tonnage modern explosives. However, almost all of the divine thunder arrows fired from distant chariots are in groups of three, one cart with three tubes, and they often surround the target's top, left, and right directions with three points when attacking the target. Under this kind of targeted covering strike, although two or three percent of the targets were able to choose the appropriate direction of dodge to escape, they often lost most of their combat effectiveness in the case of violent lightning explosions.

At first, when these cannon fodder monsters were attacked, they didn't seem to feel too strange. After all, in the feeling that this seems to be a dangerous place, and it is normal to have some ambushes, but under the sixteen rounds of attacks in just five seconds, more than 40,000 demon beasts have suffered devastating blows, and the hit rate and attack efficiency have increased sharply after approaching a distance of five kilometers, and almost within a second, tens of thousands of first-order demon beasts approaching can instantly lose their combat effectiveness, which still exceeds the expectation of Wuying, who is secretly commanding the battle.

In particular, the lightning-like thunder arrow almost does not have two sets of attacks attacking a target at the same time, but according to the distance and threat of the target, the firepower is very accurately distributed to each firepower platform to intercept and fire. Attacks are carried out with maximum efficiency with limited combat power.

Of course, Zhang Fan made a lot of arrangements and even improvements before leaving, the most important of which was to create the first pulse radar on this boundless continent and even the related fire control system through the use of talisman seals and simple electromagnetic machinery. When the light and shadow of low-level targets are even transmitted, a special sigil will transmit these targets to each vehicle and even the flying platform according to the distance, direction, threat size and sequence, and guide the operators to attack, maximizing the attack efficiency.

Of course, in the eyes of the shadowless: if these exposed firepower are all, it is not necessarily impossible to deal with...

Immediately after that, it was not the second-order level demon beasts that came to tempt it, but a hundred ghost spirits of the fourth rank and above launched a tentative attack. Ghosts that have reached the level of Jindan have a little spiritual intelligence and a strong stealth ability. In particular, the infiltration of these ghosts, who are good at stealth and concealment aura, when they are frontally pinned down by other demon beast groups on the battlefield, is almost difficult to detect by the Shenwu City monks who are only strong in building the foundation.

Soon, those ghosts approached only about two miles away from the outskirts of Shenwu City under the restraining attacks of the first-order and a small number of second-order demon beasts, and continued to infiltrate forward.

However, at this time, from the underground around Shenmu Castle, a small cannon barrel was suddenly exposed, and they opened heavy fire on the general direction of the target. Huge explosions of lightning continued to connect two miles away from the city. This time, it was not those small fights with a one-ton equivalent, but a huge explosion with a four-thousand-ton equivalent enough to cover a one-mile radius.

Thunder damage is the most extensive means of killing in the fantasy world, especially for some ghost targets that are immune to physical attacks, and it is extremely vulnerable under such attacks.

Of course, the fourth-order level ghost also had a certain amount of spiritual intelligence, and after suffering a serious setback in the initial infiltration, it began to cast a mental attack from a short distance.

Compared to the average male, female monks are slightly more resistant to mental attacks, but they have to be of the same level. A large number of Jianghu masters who had not touched the threshold of immortal cultivation were under the targeted mental attack of Jindan-level ghosts, even if the threat came from a place several miles away and seemed to be suffering a blow, they often lost their combat effectiveness in an instant under the attack of great fear, and were paralyzed in the chariot.

It's just that from the perspective of the attacking enemy outside: it seems that those ants who are not even Qi refining cultivators in perception actually have a strong mental defense ability, and they still continue to fire. Aside from a slight decrease in the density and accuracy of the fire, it seems that there is not much difference?

Of course, Zhang Fan took into account that even if the disciples of the top masters of the rivers and lakes were mainly female cultivators with strong ability to fight against mental arts, under the attack of strong mental arts, they could not be protected by simple talismans at all. Therefore, when the chariots in the array are organized for defense, they are also backed up with a central control system that is centrally controlled by the Qi refining level disciples, which is equivalent to allowing thousands of chariot platforms to automatically play a certain combat role in the array by controlling the platform and the automatic combat system.

In this way, with the continuous temptation and continuous increase of the attacker, more and more defensive means and defensive hole cards in Shenwu City had to be exposed one after another, when the second-order, third-order, and fourth-order demon beasts in Dalian were put into battle under the organization of a few fifth- and sixth-order powerhouses, the strength was already fundamentally different from hundreds of thousands of first-order demon beasts, and thousands of chariots seemed to be under pressure under the coordination of the automatic command system and many defensive means. Soon, the successive interceptive explosions were getting closer and closer, and they were again approaching a dangerous distance of about five kilometers. More and more disciples of Shenwu City who had not yet bought the threshold of qi refining also began to suffer casualties.

It was probably at this time that hundreds of flying mecha controlled by the disciples of the early stage of foundation building suddenly rose into the air under the cover of the illusion circle and started a full-scale battle. The continuous huge thunderstorms resounded in all directions of Shenwu City again, and countless nuclear bomb-like lights seemed to make up for the fire clouds that reflected the sky around the entire Shenwu City.

Although the muzzle velocity of the attacks launched by these flying mecha monks was not as fast as hundreds of times the speed of sound, the larger divine thunder arrows launched seemed to have stronger mobility and even tracking and attack capabilities, as if hundreds of end-21st century fighters carrying the nuclear warfare department formed a three-dimensional defense network.
