In Shi Leiyin's eyes, the creature of the sword thorn badger, like other magical creatures in the polar continent and pancontinent, is completely incompatible with Darwin's theory of evolution. The sword badger looks a bit like the Tasmanian devil on Earth, but it is much larger, and its body length is more than a meter, even if the tail is not counted. The head of the sword thorn badger is very close to that of the Tasmanian devil, and it has a mouth that is extremely biting, but what is really powerful about them is the place where Shi Leiyin thinks there is no scientific basis, which is the origin of their name, which is full of sword thorns all over the back.

The sword thorns of the sword badger grow a bit like that of a hedgehog, with dense spikes covering the entire back, including the head and their tail, which is nearly half their length. If it was just a sharp thorn, Shi Leiyin would not have felt that there was anything against biology, after all, there are also thorny animals such as hedgehogs and porcupines on the earth. But the thorns of the sword badger are as the name suggests, each thorn is like a well-made sword, and it is not a round sword like a foil, but like the most common kind of steel long sword, the tip of the sword is triangular, and the body is flat and has a certain thickness of the ridge. Regardless of the size of the sword, the sword thorn of the sword thorn badger is a good sword.

In fact, in the information that Shi Leiyin obtained, the sword thorn of the sword thorn badger is indeed a special weapon material. And it's not just hunters who are used to using biological materials to craft weapons and equipment, but ordinary blacksmiths also occasionally use this sword spur to make some weapons. Some Assassins would use the sword stab of the badger directly to make daggers or hidden weapons. The sword thorn of the sword badger is not metal, and cannot be detected by magic that detects metal sharp weapons. Also, because it's not metal, it's very adaptable to magic, and you can engrave magic on it. However, because they are purely biological materials, these swords are not as durable as metal, and can decay due to many different factors or environmental reasons, so in most cases, they will be specially processed by a blacksmith or alchemist before being crafted into weapons. Only Assassins who had to conceal their identities and purposes, as well as thugs who could not afford to hire someone to dispose of them, would use them as weapons.

In addition to the incredible appearance of these sword thorns, the way the sword badger used these sword thorns made Shi Lei Yin more convinced that it was a magical creature, although in the records of the Polar Continent, the sword thorn badger was definitely just an ordinary carnivore. The sword thorns of the sword badger can be fired in the direction that the sword badger needs when needed, except for the larger row of sword thorns that grow along the line of the spine. This launch relies purely on the movement of the muscles on the back of the sword thorn badger, and the range varies according to the size of the sword thorn, and the effective killing range can reach up to fifteen to twenty meters. The Sword Thorn Badger can simultaneously fire more than twenty sword spikes at a distance of 360 degrees around its body, each of which can be oriented in the same or different directions. And the most important thing is that the sword thorn of the sword thorn badger grows surprisingly fast, almost when a sword thorn is launched, a new sword thorn will grow out of the original position of the sword thorn, and grow into a sword thorn of almost the same size in a short time, and this growth time can be greatly shortened when the sword thorn badger is threatened by life, to the extent that the growth is almost instantaneous. However, the growth of the sword thorn will consume the energy of the sword badger, and the accelerated growth will affect the life force of the sword badger.

In addition to firing these fast-growing swords, the Sword Badger also has a means of attacking by using the more powerful swords on the spine line. This line of spikes grows from the back of the spur to the base of the tail, and there are usually seven to eight stabs that are nearly half a meter long. These stabs are more like forged swords than the stabs they are used to fire, and the strongest of these swords are usually used as materials. If firing a sword stab is a means of defense for a sword badger, then using a sword stab on its back to slash is an offensive means for a sword badger. When it is time to do so, the sword badger will accelerate to a very fast speed for a short time, and then hug in a ball, like a famous cartoon hedgehog, slashing at its target like a spinning cutting gear, slicing it in two with the sword thorn on its back. This offensive tactic, though peculiar as it may seem, is surprisingly effective, and is a common tactic used by the sword badger to hunt herbivores larger than its own size, and most herbivores' skin, muscles, and even skeletal armor cannot withstand the sword badger's rolling slash. However, Shi Leiyin felt that the sword thorn badger did not break the sword thorn or even the spine because of such an action, and it felt more incredible.

The sword badger targeted by Shi Leiyin is an adult sword badger. I don't know if it's good luck or bad luck, during the dinosaur's predation operation, the sword badger was digging a snow rabbit's nest, and the cunning snow rabbit became the dinosaur's tooth-filling snack while thinking that he had escaped the sword badger's pursuit. The sword badger that burrowed in the rabbit's nest in the snow field escaped the catastrophe. However, although it avoided becoming a ration for the dinosaur, the sword thorn badger was targeted by Shi Leiyin. So a day later, Shi Leiyin burrowed into the belly of the sword thorn badger.

Shi Leiyin's method of capturing this sword badger is a new method that was obtained or discovered only after the emergence of the genetic rejection problem this time. After genetic rejection, Shi Leiyin's doppelganger re-underwent the process from the initial to the current ability. In the process, Shi Leiyin found that he had some foreign fusion genes in his body. This is a very corrosive gene, and there has been a phenomenon of controlling the ontological genes in turn during the fusion process, and what caught Shi Leiyin's attention was that when the doppelganger was recovering its ability, it did not directly restore this gene, but reproduced the situation of this gene eroding the ontology and then being inhibited and devoured.

This gene sequence comes from the Lemut spider that Slimin originally devoured, but Slimin is sure that it is not the gene that the Remt spider will have, and that the vegetarian spider does not need such an ability at all. Combined with the situation at the time, Shi Leiyin thought that this gene should come from a creature that invaded and parasitized on the Lemut spider, and because he did not get all the Lemut spider body, he was not infected by that creature, and it was also possible that his devouring ability was too strong, just like this gene sequence was assimilated by his own body, and the unknown creature had been devoured and fused by himself as a nutrient.

Of course, no matter which possibility it is, Shi Leiyin can confirm that his body is not affected by the creature with this gene by checking the clone, and he already has the means to invade a creature in this way. This kind of genetic invasion of organisms is very effective, and this kind of fusion invasion at the genetic level is not only difficult to defend, but also very difficult to detect. Even if the invasion process has been basically completed, the prey will not feel anything abnormal. It's just that to reach such a level, Shi Leiyin has to first make himself the size of a bacterium, which is obviously unrealistic, and this gene sequence only has the means of invasion, and there is no information on changing body shape or body structure. Therefore, Shi Leiyin could only rely on the advantage of the slime's breathlessness to quietly approach the sword badger, and while it was sleeping, it invaded the inside of the sword badger from its nose, mouth, and ears, which is why this sword badger would jump like thunder and attack the surroundings indiscriminately.
