Disciple, please let me go.

There are many things in Tianyi Sect’s treasure house.

It can be roughly divided into four items.

The first item is spirit stones, which number about more than 3,000 pieces. Obviously Tianyi Sect has also discovered the spirit stone mine, otherwise it would not be able to reserve so many spirit stones.

The second item is elixirs and elixirs, some of which assist cultivation, some of which directly improve cultivation, and some of which heal injuries and illnesses.

The third item is spiritual materials, various kinds of spiritual materials.

The fourth item is the inheritance jade slip, but the content on it is only about the Qi refining realm, which does not arouse Li Dong's interest at all.

After all, compared to the various complete inheritances of Sanxian Island, these simple inheritance jade slips are really unattractive.

Disappointed, Li Dong was overall very disappointed with the treasure house of Tianyi Sect.

After all, none of these things can directly improve his strength.

"Let's study the Soul-Slaying Flying Knife and the bloody dagger first."

With this thought in his mind, Li Dong took out the Soul-Slaying Flying Knife without hesitation and prepared to refine the Soul-Slaying Flying Knife first.

"Woooooooo..."

As Li Dong took out the Soul-Severing Flying Knife, an indescribable ghostly cry emanated from the knife.

The sound was not loud, but it had a penetrating effect on people's hearts.

Just hearing it makes people feel upset.

This is still a situation where the power of the soul-cutting flying knife has not been activated. Once the power of the soul-cutting flying knife is activated, the power will be even more terrifying.

After Li Dong's true energy was continuously integrated into the Soul-Severing Flying Knife and he completely refined it, he understood why the Soul-Severing Flying Knife was regarded as a killer weapon by Liu Wandao.

The soul-slaying flying knife contains countless wronged souls. When its power is activated, a powerful soul-capturing sound will be produced at the moment the flying knife flies out.

Before the foundation was established, the souls of the monks had never been transformed. When attacked by the soul-stirring sound, they would lose their souls in an instant. Naturally, they could not avoid the attack of the soul-cutting flying knife.

Therefore, in the battle in the Qi Refining Realm, the Soul-Slaying Flying Sword can always hit the mark, and there are truly no missed shots.

More importantly, the damage method of the soul-cutting flying knife is not just a simple physical method.

The damage of the soul-cutting flying knife is directly aimed at the soul.

Once struck by the soul-cutting flying knife, the soul will be cut out of the body by the soul-cutting flying knife and sucked into the soul-cutting flying knife, becoming one of the dead souls in the soul-cutting flying knife.

Therefore, as long as you are hurt by the Soul-Severing Flying Knife, even if it is just a minor wound, it will be fatal.

However, although the Soul-Slaying Flying Dagger is powerful, it also has a major drawback: it consumes a lot of mental energy.

A normal Qi Refining Realm monk would only need one strike to exhaust his spiritual power. A second strike would consume the power of his soul.

This is a magic sword. If you don't have enough mental strength to burst out by force, you might be sucked to death by the magic sword first.

Although Liu Wandao, the true disciple of Tianyi Sect, is considered powerful among the Qi Refining Realm monks, he is not the type with extraordinary mental talent.

With his strength, at most one attack with the Soul-Severing Flying Knife would exhaust his mental energy, and even temporarily reduce his combat power. Without more than a month to recuperate, he would not be able to recover at all.

It was also for this reason that Liu Wandao, the true disciple of Tianyi Sect, did not use the Soul-Slaying Flying Knife to fight Li Dong at the beginning of the battle.

But he acted too late after all.

The distance between him and Li Dong was too close. From the moment he took out the soul-cutting flying knife, Li Dong felt a huge threat from the soul-cutting flying knife.

In this situation, how could Li Dong give him the opportunity to launch an attack with his Soul-Severing Flying Knife?

Therefore, Li Dong did not hesitate to unleash the terrifying evil spirit contained in the Blood Dragon Spear, attacking Liu Wandao by surprise and directly killing him.

But even if Li Dong won that battle, he would not underestimate the Soul-Slaying Flying Knife.

Especially now that he understood the characteristics of the soul-cutting flying knife, he felt that the soul-cutting flying knife was extremely terrifying.

After all, the Soul-Severing Flying Dagger is a magic weapon that can be continuously strengthened. As long as you keep killing enemies, you can swallow the enemy's souls into it, increasing the power of the Soul-Severing Flying Dagger.

Theoretically, it is a magic weapon with unlimited power.

In this respect, magical weapons are far inferior.

It is very difficult to upgrade magical weapons, and it requires engraving magical restrictions on them layer by layer.

It would take at least a thousand years to cultivate a magical weapon to the level of an immortal weapon, and the embryo of the magical weapon must be strong enough.

Ordinary magic weapon embryos cannot imprint too many mana restrictions at all, and the upper limit is only an ordinary magic weapon at most.

However, the Soul-Severing Flying Dagger has no such limitation at all. If it were allowed to kill people freely, it might become a magic weapon that could kill immortals in a dozen years.

After understanding this, Li Dong suddenly understood why the magic soldiers were so harmful and why so many people persisted in using them and eventually became their puppets.

After all, many cultivators have limited talents, and the inheritance they obtain is also very ordinary. They cannot even get over the hurdle of building a foundation in their entire lives.

Even if they can boast of being able to surpass the threshold of foundation building, many people will be stuck in the foundation building realm, and those who can break through to the golden elixir realm are rare.

To exaggerate, out of 10,000 monks, there are probably no more than ten who can break through to foundation building.

Among ten thousand foundation-building cultivators, only one can reach the Golden Core stage at most.

The higher you go, the harder it becomes.

In myths and legends, there are a hundred thousand heavenly soldiers and generals in the heaven alone, and each of them has at least the cultivation level of a True Immortal. It seems that it is very easy to break through to the level of a True Immortal.

But all that is just an illusion.

The 100,000 heavenly soldiers and generals were accumulated over countless years after the creation of the world.

On average, only a handful of true immortals are born every hundred years.

Therefore, the difficulty of breaking through to the True Immortal is even higher than that of a person building an airplane or rocket with bare hands.

Having a magic weapon can make many people who have no ability to break through the realm. Having the combat power of a true immortal level will naturally make countless people crazy.

Therefore, even if they know that using magic weapons is a dangerous act that can hurt others and themselves, not everyone can resist the temptation.

Even Li Dong, after thoroughly understanding the function of the Soul-Severing Flying Dagger, couldn't let it go. He felt that the Soul-Severing Flying Dagger could become his hidden weapon, helping him kill powerful enemies at critical moments.

Moreover, his mental power is very strong. Li Dong conservatively estimates that it is ten times that of a normal cultivator.

This is the qualitative change that the body of the Demonic Dragon brings about when it breaks through to become a grandmaster, so Liu Wandao, the true disciple of the Tianyi Sect, will exhaust his mental power when he unleashes the Soul-Slaying Flying Knife once, but Li Dong can unleash it ten times.

Moreover, Li Dong conservatively estimated that if he exploded within three times, his mental power would not be damaged at all, and he would not need to rest to restore his mental power.

A soul-slaying flying knife brought such a big surprise to Li Dong that Li Dong could not help but take out the blood-red dagger again, wanting to see how much change the blood-red dagger could bring to him.
