The protective layer formed by the protection program and the shield force layer formed by the shield program are both composed of runes, and both have protective effects. However, the protection program is generally used to protect the talisman, while the shield program is generally used to protect the person. There are a number of reasons why these two types of protection, which are similar in nature, are used differently in this way.

First of all, there is a slight difference in the way they are protected. The working principle of the shield talisman program is that the program composed of a mass of slots emits a rune force, forming a layer of rune protection at a certain distance outside the person's body to prevent the attack of external forces (including light and dark). This program can be a built-in program in the dark domain of the human body, or a magic rune program, and the advanced ones can also use shield charms. The protection program is on the surface of the dark domain of the tactical talisman or the flying talisman, and the card position forms a procedural shell covering the entire talisman in the form of a net. This shell emits a spell to block the intrusion of external forces, and it itself is also extremely strong and has a strong ability to resist blows. If we have to make an analogy between these two protection methods, it can be considered that the principle of the protective layer formed by the shield is like opening a protective umbrella, and the protection principle of the protection program is more similar to wearing a body armor.

Second, the degree of control between the two is also very different. When the warriors control the shield power, they can only roughly control the overall strength of it, as well as the distance and direction from the body, and other simple matters, and do not have the functions of opening holes in the shield rune power cover, enhancing local strength, and allowing slow spiritual air flow to pass through. But if the protection program is designed in advance, it can do this. A set of fully functional protection programs, warriors can arbitrarily open a gap in the protective layer, which can instantly increase the protection strength of a certain point, and can also allow low-speed spiritual energy to enter while resisting the attack of high-speed aura projectiles at it, and replenish the spiritual energy inside the talisman. In addition, it can also be loaded with speed increase functions, such as the function of devouring the air in front and spraying it in the rear, which not only increases speed, but also reduces drag and air vibration, and does not produce an air explosion even when the speed of sound is exceeded. At present, the protective shield formed by the Soul Eater outside this insect chrysalis shield is also using this function to absorb the aura from the outside world into the interior. What everyone doesn't know at the moment is that the thermal radiation that rebounds from the protective shield is actually just a very small amount of energy that escapes into the bright realm when the physical aura bomb hits the protective shield, and most of the aura energy generated by the aura bomb in the dark world is absorbed into the protective shield and provided to the huge insect chrysalis retreat.

Finally, since the protection program is so easy to use, and the protection is stronger than the shield charm, why are alien humans still using shield charms, but the protection program has not become the mainstream protection method for alien humans? It's a matter of cost and efficiency. While there are many benefits to savers, they are too complex and require too many slots. Still taking Lang Tianya himself as an example, his protection program is the protection program of the copied Reiki Needle. But the Reiki needle is just a thin needle, its surface area is very small, it has nearly a thousand card slots inside, but it needs nearly a hundred card slots for the protection program. And Lang Tianya wants to completely replicate this kind of protection procedure on the surface of his body, to be honest, move all the more than 100,000 card positions in his dark domain to the surface of his body, which is almost enough to cover one leg. Based on his special ability to make the card slot move, he often cut corners when using the protector program, and only reluctantly got it to work. For example, only local critical positions are protected, such as only opening the speed increase function. If he wants to keep the protection program running at full capacity, he may not have another four or five hundred thousand cards.

Lang Tianya is still like this, just imagine how expensive it would be for an ordinary martial artist to cultivate a set of protection procedures in the dark domain. Even if a martial artist spends his entire life, he may not be able to get together the card slots required for a set of protection procedures, let alone arrange them on the surface of the body to form a net-like program. In fact, in a word, the small size of the talisman can of course use the protection program, but with the size of a human being, it is more cost-effective to use a shield talisman. As for whether there is a costume-style external protective talisman in the alien world, Lang Tianya has no way of knowing.

Lang Tianya guessed that the reason why the shield monsters could form the protective shield of this kind of protection program was because they also had some ability to move the card slots, and they could transform the shield program in the dark domain into this kind of combined protection program. The second is that they are highly trained, and the controller is skillful, to produce such a strong protective shield. When he showed his head just now, it was the moment Steven was thrown into the protective shield. The operator's instantaneous operation of the notch switch on the protective cover is too amazing, and he is admired for throwing himself to the ground. He guessed that the controller should have used some kind of runic power to directly act on the dark domains of other shield monsters, and change the position of the stuck positions in their bodies, so as to control the protective shield. Because if you let the shield monsters adjust themselves by giving orders, I'm afraid the reaction speed will not be so fast. Lang Tianya thought to himself, if it was the card position in his own body, he should have no problem operating so quickly, but if he changed places and let him control the dark domain of five hundred individuals, he would definitely not be able to do it so accurately.

But even the best things have drawbacks. And generally speaking, the more accessibility features, the more flaws. This is especially true for human-controlled systems. If the Soul Eater's protective shield was simply used to resist attacks from the outside world, then Lang Tianya couldn't do anything, but now, they have loaded it with a soul-sucking function, which is problematic. For others, of course, this is not a problem at all. Because if you don't feel it firsthand, no one can know the direction of the flow of aura in the outside world, and you can't find the weaknesses in it. But it's different in Lang Sanya. In his eyes, the surface of the protective shield was absorbed by the flow of spiritual energy to form colorful swirls, like small tornadoes swimming on the surface of the protective shield. Everywhere they went, small aura entrances were formed, leading straight into the protective cover. These aura entrances are small, they are the same as non-existence for the size of the aura bullets, but for Lang Tianya, they are the back doors that enter the inside of the protective shield.

Lang Tianya virtualized the nine aura needles and sneaked into the dark world, trying to make them loose and separated, disguised as ordinary aura particles and flowing with the aura flow, and slowly approached the aura vortex on the protective cover. Soon, they were captured by the suction of the aura vortex and sucked into the inside of the protective cover. That is, the externalized virtual talisman like the aura needle, if it is other talismans, whether from the physical perspective or from the perspective of manic operation, it will not be able to invade other people's protective shields like Lang Tianya. According to the normal path, after the aura enters the protective shield, most of them will enter the pupa through several channels composed of runes for energy storage and backup, and a small amount will enter the dark domain of the shield monster to replenish the aura loss when they run the program.

Lang Tianya did not let the aura needles enter the pupae, but let them enter the dark domain of the nine shield monsters respectively. Just as Paul was directing the soldiers to shoot at the false weak points on the protective shield, Lang Tianya saw that five of the weak points were composed of the runes emitted by the shield monster with the aura needle in its body. Just as the five physical aura bullets were approaching the five landing points, he suddenly attacked and used the aura needle to directly destroy the program modules in the dark domain of the five shield monsters.

This moment is also the moment when the monkey monster shoots bone spurs at Wang Xingang. The moment Lang Tianya caused damage, it discovered the problem, but it was obviously too late to remedy it. It didn't even look to see if the bone spur had stabbed its target, and turned around and pounced on the pupa that had not yet been closed.

Five Entity Aura Bullets accurately bombarded those five weak points. But this time, instead of camouflaged weak points, they really became five weak points. The aura bullet passed through the protective shield and hit the shield monster behind directly, and each aura bullet exploded after it had pierced through the heads of at least two shield monsters, and this was only an explosion on the surface. In the dark world, the high-speed aura generated by the compressed aura contained in the living bullet directly cut through the dark domain of the shield monsters, completely destroying the program in their bodies. There are at least four or five shield monsters killed or injured around the five hit points. Because of the lack of personnel, five large gaps immediately appeared in the protective cover.

How could Paul have missed such an opportunity. While he directed his soldiers to fire at the five missing shots, he again fired two hundred and forty rounds from the frame. Countless bullets entered through these five gaps, tearing all the shield monsters to shreds in an instant. The entire shield lasted only a few milliseconds before disappearing. Then there was a series of circular explosions, an unprecedented shock wave radiating in all directions, and people were caught off guard and attacked. Some people with weak internal strength were even directly pushed to the head, and rolled down the mountain with the rocks shaken by the shock wave. After the shock wave, people have the opportunity to open their eyes and see the scene. I saw that the scene was like a Shura field, the pupae and shield monsters were gone, and only the ground was full of broken flesh and rotten armor, and gray blood flowing to the low-lying places.

The people on the surrounding hillside burst into loud cheers. Samantha put away her gun and spread her wings on her rack and flew down the mountain. Now the situation below is clear at a glance, the largest piece of meat is no bigger than a palm, and there is no complete monster that can pose a threat, so there is no need for her to go over with a gun. She only fired one shot just now, and it was not in the protective cover, but the bone spurs that the monkey monster threw at Wang Xingang. As soon as the bone spur came out of the protective shield, her bullet hit the bone spur accurately. But the bone spur wasn't shattered to pieces as she had thought, it just flew off target and landed on the ground in the distance. The purpose of her flying down was to take a look at Wang Xingang's injury, and second, to retrieve the bone spur and take it back to study.
