Long, long ago, when the rabbits just came to the Mo world to participate in the first monster siege, the rabbits who had witnessed the power of the city defense array had a strong interest in the defense array.

After all, the external shield has always been a very discussive topic. It is basically standard in science fiction movies. There are no two or three of them on the body, and they don't have the face to see aliens.

At present, the local government also attaches importance to this aspect and has some research results - of course, the results of the latter are very simple.

One of the relatively mature research directions is to achieve the effect of external shield by attenuating shock wave by electromagnetic arc.

This was a patent applied for by Boeing - at that time, the news also caused a routine of "as long as my voice is louder than the bomb, can I offset the bomb shock wave?".

Another is the Tokamak of fusion reactor, which uses magnetic force to restrict the fusion reaction within a certain range without solid shell.

As for the universe, the earth's magnetic field resists the solar wind, which has a similar concept.

However, no matter which of the above examples, it is still a certain distance from the energy shield that can isolate kinetic energy weapons in our traditional science fiction.

But the situation in the Mo world is different.

The shield formed by their talisman or array can isolate kinetic energy and energy weapons!

In the face of this kind of object that has knowledge but is not completely inaccessible to the principle, the physics research team led by Zeng Gucheng studied the city guarding array almost on the day when they moved into chixian city.

Later, when Hua Jun's team cracked the first-order talisman, the research team also conducted a systematic attitude analysis on the psionic shield.

Don't think it's unrealistic.

Whatever the array or shield of the great Mo world, its essence depends on aura, which is no problem, but its attitude must be a kind of material - just like the smoke and sand giant mouth composed of monsters in xiaolianzi mountain, it should have "sand" as the carrier.

Even if the final analysis shows that the composition of the shield is a crystal composed of solid aura or a pure particle wave, it is also the category of declarative matter.

Because under the existing Planck system, it is impossible to allow the Mo world to have memes other than declared substances. This is the most basic rule of the operation of the universe. In the words of fantasy novels, it is "the will of heaven".

Therefore, Zeng Gucheng and his team have carried out long-term research on array shield with this concept, and finally found a core element:

Tritium!

Tritium, also known as ultraheavy hydrogen.

It is one of the isotopes of hydrogen. Its nucleus is composed of one proton and two neutrons. It is radioactive and will occur β Decay.

Tritium in nature is that when the high-energy neutrons carried by cosmic rays bombard the deuteron, its deuteron and neutrons combine into tritium.

In industry, tritium is produced by using reactor neutrons and lithium-6 compounds as targets.

According to the research of Zeng Gucheng's team, tritium is contained in most low-level Reiki shields in the Mo world, but strangely, this Reiki shield is not radioactive.

The specific reason is that the physics team is still in progress. After all, the road should be taken step by step.

In short, after determining that tritium is contained in the shield, a new guess appears at any time:

If the shield is instantaneously frozen with liquid nitrogen, is it possible to disorder its molecular structure and make it disintegrate and fail?

This is a guess completely in line with the chemical theory. The final experimental result is naturally

sure!

Based on the above experimental results.

This time, the rabbits specially equipped Wu Zhishi with a large number of liquid nitrogen capsules and directly spread them at low altitude on the moat of yangbei city.

According to the experimental results of Zeng Gucheng's team, the destruction effect of liquid nitrogen will consume a lot of aura in the core of the array, and the instability principle will also inhibit the generation of subsequent arrays. Therefore, it is difficult to recover the city protection array quickly in a short time.

Return to the battlefield.

The fragments of the broken moat array vaporized instantly and had no impact on the people on the city wall.

But Mo Daolin felt that the fragments were like knives, one by one across his face and heart.

It was not until a few seconds later that the screams on the wall brought his attention back to reality.

At this time, the city wall had already been in a mess, and there were panic fleeing defenders and even practitioners everywhere.

After all, fools can think of what will happen after the city defense array is broken.

At the same time, three wuzhi10 also began to attack.

Considering that there are a large number of innocent mortal sergeants in the city garrison.

Wu Zhishi did not directly launch airborne missiles, but used machine guns to shoot targeted targets that were obviously practitioners, regardless of life or death.

According to the family rules of the Wei family, after reaching the fourth floor of Qi cultivation, all cultivation resources should be exchanged through family contribution points. Gathering a refugee to the iron mine can only exchange a little.

Therefore, one of the Wei family members who are qualified to come to the city wall is counted as one. Since the iron ore mining, each person has at least indirectly borne the lives of dozens of refugees.

Therefore, Wu Zhishi's drivers attack without fear, which is justice coming.

"Ah --!"

A scream sounded in his ear, and Mo Daolin looked at it subconsciously.

Not far away from him, a six layer practitioner of Mojia Qi with a bow and arrow was lying on the ground in pain, and there was an obvious wound in the inland sea of his abdomen.

At the same time, there are still some small things falling in the sky. When they burst open, they are either dazzling for a short time, or they keep crying.

Gulu——

Mo Daolin swallowed his saliva and suddenly thought of something:

"By the way, the main house, there are several killing arrays in the main house!"

The main house of the Mo family has been inherited for more than 200 years. In addition to the defense array, there are many attack and kill arrays, and even some secret roads leading to the outside of the city!

If you can escape back to the main house, there may be a way to live.

At this time, Mo Daolin also understood that the other party was obviously prepared.

With the destruction of the moat, even if there is only one base building friar among the visitors, it is enough to crush any practitioners in yangbei city one by one.

It can't be said that Morrison was too careless and didn't leave enough strength or relevant preparation plans in the city.

After all, from Morrison's point of view, this is a situation that can no longer be stable.

The moat array uploaded from the ancestor of yangbei city can resist the attack of jiedan territory for several hours. Within a thousand miles, only five fingers of the city can break the array, and all of them are 300 miles away from yangbei city.

In this case, it doesn't make any difference whether the left behind personnel build the base or practice Qi. Instead of arranging a left behind person to build the base, it's better to transfer the combat power to the front battlefield.

But who could have thought that Morrison was not only trapped, but the city protection array of yangbei City, which was enough to resist jiedan territory, was also inexplicably broken?

After all, no one in the Mo world has prepared liquid nitrogen to break the shield. The lowest temperature of some ice spells is minus 50 or 60 degrees.

In short, no matter what happened from beginning to end, at least yangbei city can't be defended now - but similarly, in Mo Daolin's opinion, these people in Chicheng County can't occupy yangbei city.

No matter what kind of strong support the Wei family has brought to Chi County, it can be seen that their high-level combat power must be limited by the fact that only one base building practitioner came to yangbei city.

Therefore, Morrison and other six foundation builders are probably just tied up. Maybe one or two people will fall, but it is impossible to destroy them all. When they return, they will be able to organize a wave of counterattack.

Therefore, as long as Mo Daolin can hide until Morrison returns, even if he has to be punished for his old generation, he will be absolutely limited.

At most, they are sent to see mines for a few years. In any case, they can't and won't be punished.

Thinking of this, Mo Daolin immediately turned around and prepared to escape to the main house.

However, before he ran a few steps, a figure jumped out of the air and the golden saber was in front of him.

"Old man, where are you going?"

As the contemporary patriarch of the Wei family, Wei Fan naturally knows the Mo family's elder. After all, Chicheng County and yangbei city are only a hundred miles away, which is regarded as a standard conceptual neighbor.

Therefore, the high-level leaders of both sides will know more or less about each other, such as foundation builders, patriarchs and elders.

Looking at Wei Fan in the way, Mo Daolin didn't speak, but raised his fist vigilantly, and his whole body was magnificent.

He is the master of the Mo family's secret method, benlei boxing. His realm is also nine levels of Qi. He is not afraid of Wei Fan.

As soon as the breath was transferred, he rushed to Wei Fan!

Just as Wei Fan knew him, he also knew Wei Fan's identity and knew that the contemporary patriarch of the Wei family had a huge tripod in his hand.

It's a very powerful magic weapon. Once sacrificed in today's battlefield, it will be difficult for him to escape back to the main house.

Therefore, only close combat and hand to hand combat can limit the exertion of Dading magic tools to the greatest extent.

Meet on a narrow road... The brave wins!

However, Mo Daolin rushed and suddenly found that Wei Fan was not ready to sacrifice a magic weapon, but lifted a thick black pipe.

Mo Daolin raised a trace of contempt at the corners of his mouth:

"Concealed weapon? Bow and crossbow? Don't you smell the fist within seven steps..."

However, before his idea was fully realized, Wei Fan took action.

Dada dada——

A series of specially made bullets containing a small amount of monster crystals flew out of it, instantly penetrated Mo Daolin's body surface defense, and beat his inland sea into a sieve in less than half a second.

Then Wei Fan came up to him and shook his head:

"This is the bullet I bought in exchange for my meritorious service in the battle of xiaolianzishan. Old man, times have changed."

Then he was about to capture Mo Daolin, when he suddenly thought of the sneak attack that Morrison had just known about refining his eyes into magic tools.

"Don't you have any Yin hands, old man?"

Wei Fan looked at the city wall battlefield that was gradually ending around him, thought for a few seconds, and stepped forward with a knife.

Meanwhile, in the firewood camp.

Hua Xiaomo, who was jumping in front of Mr. Yuan, was suddenly surprised. He inexplicably covered the back of his neck, as if he remembered something unpleasant
