The biggest strength of the corpse demon is that the body is hard and the strength is strong, but the disadvantage is that there is no means of long-range attack, because the corpse demon cannot use true qi, and the attack range of corpse poison is not large.

If you want to improve the strength of the corpse demon in a short period of time, you must make use of your strengths and avoid weaknesses, and give full play to the strengths of the corpse demon's physical strength.

One of the best ways to do this is to refine a pair of heavy armor for the corpse demon.

Li Yi has the alchemy skills of the Dayan faction and the Holy Spirit faction, and it is not too difficult for him to refine the heavy armor, but the difficulty is to refine a heavy armor that is most suitable for the use of corpse demons.

The corpse demon has no true qi, that is, even if the magic circle is depicted, it cannot be urged.

And if all of them are not depicted, the power of the heavy armor will be greatly reduced.

"You can only use spirit stones as the source of urging the magic circle!" Li Yi secretly pondered, "But the spiritual energy provided by the spirit stone is limited, and it is not like true qi, it can maximize the power of the magic circle, if a large number of spirit stones are placed, it will look bloated!"

This put Li Yi in a dilemma.

In his mind, he had even imagined the appearance of the corpse demon wearing heavy armor, at that time, it was not just a corpse demon, but equivalent to a humanoid magic weapon, but in the final analysis, the corpse demon could not use true qi, this was a dead hole, and it could not be made up.

After thinking about it for a while, Li Yi couldn't think of any way to solve this problem, and he couldn't help but feel quite discouraged.

"If you put on heavy armor and turn into a humanoid magic weapon, it will really be a god blocking and killing gods and Buddhas, but it's a pity......" Li Yi sighed mournfully.

At this moment, a spiritual light suddenly flashed by.

"Wait, humanoid magic weapon!"

Li Yi's eyes widened, and a bold, even somewhat ridiculous thought popped up.

"Why don't I just refine the corpse demon into a magic weapon?"

This thought made Li Yi feel a little crazy, but in fact, in the early refining school, there was a faction called the Holy Yang faction, which had made such an attempt, but it was just to directly use living people to try, trying to carve magic circles on living people and refining living people into magic weapons.

However, the human body is difficult to withstand the power of the magic circle after all, and when the magic circle is urged, the power that bursts out will first tear the human body apart, and finally become a self-detonation magic weapon at most.

Therefore, it is conceivable that the attempt of the Holy Yang faction ended in failure, and later with the continuous evolution of the refining school, the Holy Yang faction was completely eliminated, and the attempts it made also became a secret.

The reason why Li Yi knew about this was because he heard his master Yang Xiaohua talk about it by chance, saying that the Holy Spirit Sect had a little intersection with the Holy Yang Sect a long time ago, so there were some records of the latter.

At the beginning, Yang Xiaohua said that the demise of the Holy Yang faction was inevitable, because it was too evil, and the Holy Spirit faction was known as the first refining school of the cult, which was very evil, but compared with the Holy Yang faction, it was a small thing.

Directly refining living people into magic weapons, it feels terrifying to think about.

Because the magic weapon belongs to the instrument in the final analysis, not a living being, even if it is a spiritual weapon or a dao weapon, with spirituality, it cannot get rid of the category of the instrument, it is impossible to produce seven emotions and six desires, and it is impossible to fight automatically without the control of the master, let alone cultivation.

But once a living person becomes a magic weapon, it will be completely different, a magic weapon with super high wisdom and automatic cultivation is simply an existence at the level of the heavens, if it is really successfully refined by the Holy Yang faction, I am afraid that the world today is not the Great Xuan Dynasty, but the Holy Yang faction.

"The reason why the Holy Yang faction failed was because the living body was not tough enough, but the corpse demon seemed to be able to solve this problem...... "The more Li Yi pondered, the more feasible he felt.

After absorbing the corpse poison, the corpse demon has undergone a great metamorphosis, becoming extremely hard, and the corpse demon will not feel pain, and can be further transformed, incorporating various other materials into its body, so that its body can fully withstand the power of the magic circle.

The corpse demon itself can refine many kinds of materials, such as Xiao Qi, who once ate a lot of Li Yi's refining materials, forcing Li Yi to have to place her alone in a storage bag.

In terms of physical strength, Li Yi felt that the corpse demon should be able to have the conditions to become a magic weapon, although the spiritual intelligence of the corpse demon could not be compared with a human, but compared with a normal magic weapon, it was inferior.

After giving the battle order to the corpse demon, the corpse demon will take the initiative to fight, and there is no need to manipulate it all the time, and even be able to comprehend some simple tactical intentions, which is incomparable to normal magic weapons.

Not to mention a spiritual weapon, even if it is a Dao weapon that condenses the Great Dao, it is not so spiritual.

As for the shortcomings of the corpse demon's inability to use true qi, it has also been well solved, after refining the corpse demon into a magic weapon, before each battle, as long as the corpse demon swallows a large number of spirit stones.

The stomach of the corpse demon is not very different from the stomach of ordinary people, not only can it hold more things, but it is also very tough, and everything that enters it will basically be forcibly ground and refined.

In other words, the stomach of the corpse demon can take a similar effect to the dantian to some extent.

All the problems were solved, and Li Yi couldn't find a reason not to give it a try.

As soon as he said he would do it, he decided to use Kunshan for his first attempt.

Among the five corpse demons, Kunshan is relatively the weakest, even if it fails in the end and causes the corpse demons to be damaged, it will not be too heartbroken.

The first is to strengthen Kunshan's physical body to a level that can withstand the power of the magic circle.

The reinforcement material Li Yi chose was Xuanjin.

As one of the most widely used refining materials, Xuanjin has long been loved by all refiners, this material is tough enough, stable in nature, can blend well with most materials, and relatively speaking, the price is relatively affordable.

Among the materials that Li Yi scavenged from the Bijia treasury, there were a full three thousand catties of Xuanjin.

He first took out ten catties of Xuanjin, urged the true qi, melted it into gold water, and then ordered Kunshan to drink it and refine it.

On the surface of Kunshan's body, a faint gold color gradually emerged, becoming more and more hard.

Then, Li Yi began to carve the magic circle on the instep of his foot.

The magic circles of the Dayan faction and the Holy Spirit faction add up, there are more than two thousand, among which there are some extremely powerful magic arrays, which Li Yi has not yet mastered, and the more powerful the magic array, the higher the requirements for materials.

Therefore, Li Yixian chose one of the most basic magic circles in the Holy Spirit faction, called the Tengyun magic circle.

After carving this magic circle, it can make the magic weapon light, and the speed is fast, like a cloud driving through the fog.

Li Yi had carved this magic circle countless times, and he was already extremely familiar with it, but it was the first time to carve a formation on the corpse demon's body, and he couldn't help but feel a little nervous, his fingertips were as true as knives, and every rune was carved carefully, lest something go wrong.

An hour later, Li Yi wiped his sweat and let out a sigh.

I saw that on the instep of Kunshan's left foot, there were dense runes, and there was an additional magic circle, which was the Tengyun magic circle.

It was more difficult to carve a magic circle on the corpse demon than he had imagined, but fortunately, he was now a master of alchemy, and he was a master of alchemy, so nothing went wrong.

Li Yi took out another spirit stone and let Kunshan eat it.

Kunshan's face was expressionless, and he swallowed a spirit stone into his stomach in two bites.

After half a ring, there was no movement in Kunshan, and there was no sign of the Tengyun Circle on his feet.

"Still can't do it?" Li Yi was a little disappointed.

But at this moment, only a swishing sound was heard, and a burst of dazzling light bloomed on Kunshan's left foot, soared into the air, and flew obliquely into the sky, flying straight for a while, before the aura was exhausted and fell.

Li Yi was overjoyed, grabbed him in the air, and grabbed him back to the dead wooden boat.

Kunshan's left foot is almost intact, except for a slight tear in the skin.

"Great!" Li Yi cheered in his heart.

Although it was only the most basic magic circle, it at least proved that his idea was feasible, as long as more materials were integrated into the corpse demon's body, it would definitely not be difficult to refine the humanoid magic weapon.

The corpse demon who can fly to the sky and swallow the clouds and spit out the fog will definitely be able to open the eyes of the world.

If the corpse demons refined by the Corpse Demon Sect back then were all this kind of corpse demons, I am afraid they would not have been wiped out by the Zhennan Palace.

However, it is a pity that the Corpse Demon Sect has not made such an attempt, and even if it did, it would not be possible, because the reason why Li Yi succeeded was because he combined the Great Yan Alchemy Technique and the Holy Spirit Alchemy Technique at the same time.

The two major alchemy techniques ranked first and third in the Great Xuan Dynasty, after Li Yi's integration, can almost be described as flawless, and because of this, only he can successfully carve a magic circle on the corpse demon and operate successfully.

Because in the final analysis, the corpse demon is not a formal refining material, and as long as there is a slight difference in the nature of the refining material, the impact will be very huge, which requires that you must be very familiar with the corpse demon itself, and you must also have extremely superb refining techniques.

In the whole world, only Li Yi can meet these two points at the same time.

His alchemy skills naturally need not be said, and at the same time, he also cultivated the Corpse Demon True Scripture, and he has been with Xiao Qi for a long time, so he was very familiar with the Corpse Demon at that time.

For other people, even if they are refining masters, it doesn't help if they don't understand the Corpse Demon Sutra, and the former Corpse Demon Sect understands the Corpse Demon Sutra, but their alchemy skills are far from enough.

"You still have to further improve the strength of your physical body to be able to withstand the more powerful magic circle!" Li Yi began to ponder the next steps.

He took out a hundred catties of Xuanjin again and let Kunshan devour and refine it.

After a while, the golden yellow began to precipitate, penetrating deep into the skin, and the color became much darker, but the strength was greatly improved.

After Kunshan was refined into a corpse demon, his physical body was already quite strong, and at this time, the strength of his physical body had surpassed that of Xuanjin.

"Almost. Li Yi immediately started the next step, portraying a more powerful magic circle.
