This mutation was caused by the Colorful Fire Sparrow.

At the beginning, the Colorful Fire Spirit Sparrow also went to the prehistoric ruins, and when the Heavenly Sword Martial Saint found it, it was carrying the body of the Spirit Warrior Saint and was seriously injured and dying.

Originally, it was also a Martial Saint cultivator, but because it was extremely injured, even if the Heavenly Sword Martial Saint tried his best to save it, it failed to recover its cultivation, and it was left with serious dark injuries.

After the Heavenly Sword Martial Saint left, it was extremely resentful, feeling that the Heavenly Sword Martial Saint was irresponsible, and it took thousands of years to cause the fall of the Spirit Martial Saint, and it also caused it to retreat.

However, the sword spirit has always persuaded it, so when it was alive, it didn't do anything out of the ordinary.

But more than 3,000 years ago, its dark wounds attacked, its longevity was exhausted, and when it was dying, the resentment that had accumulated for thousands of years all erupted.

This resentment did not dissipate, and it fused with its remnant soul, possessing a sword intent spirit at the third level of the martial arts inheritance, and turned into an extremely ferocious evil spirit.

Because the evil spirit carries all the grievances of the Colorful Fire Spirit Sparrow, it is bent on getting the inheritance, killing the Heavenly Sword Martial Saint, and "avenging" its master.

Originally, there was a strong prohibition in the third level, so the cultivation of the spirit of sword intent could only reach the fourth level of military generals.

But fusing the memories of the Colorful Fire Spirit Sparrow, the evil spirit found a loophole in the prohibition, and now it is the peak cultivation of the military general, and it is about to break through the Wuhou.

Once it breaks through the Martial Hou, the prohibition of the third level will no longer be able to trap it, and it will take control of the Heavenly Sword Palace and take the inheritance of the two Martial Saints as its own.

The evil spirit is fierce by nature, if it is allowed to be inherited and leaves the Heavenly Sword Palace, the harm is only on the remnant soul of the evil dragon Ao Lie.

"The third level, originally there is not much requirement for your cultivation, only need to test your sword intent comprehension......"

The sword spirit said solemnly: "But now the evil spirit is the peak of the general, and the combat power is comparable to that of a five-star genius......"

"With it, it will be difficult for you to complete the third level of the test, and you may even die in it......"

With a hint of anticipation, the Sword Spirit asked, "Are you sure you want to conduct the inheritance assessment?" ”

"Yes!"

Jiang Tian looked at Qin Mengyao to see what her opinion was, but Qin Mengyao nodded without hesitation.

If there was no reason to come, how could she have paid such a big price and traveled millions of miles.

"Okay, count me in."

Jiang Tian naturally would not retreat, if there was no opportunity to go against the sky, let alone settle accounts with Qin Wuji and the cyan figure, I was afraid that even the three-year appointment with Jiang Ri would definitely be lost.

What's more, Yun Hao is not dead, his identity in his previous life is very likely to be revealed, if he doesn't seize every opportunity to improve his strength, I'm afraid that he won't even know how to die at that time.

"That's ......"

A smile appeared on the sword spirit's face, and he said to Jiang Tian and the others: "Since you are determined to conduct the assessment, of course I will not let you take risks in vain......

"In the first and second levels, there are a lot of cultivation resources, and it was originally extremely difficult to obtain, but I will control the main formation and reduce the difficulty as much as possible......"

Sword Spirit Zhengse advised: "You must seize every opportunity to improve your strength, otherwise with your current strength, the third level will definitely die." ”

"Yes, Senpai."

Jiang Tian and the others knew the seriousness of the situation, and they all looked solemn.

"Come with me, go to the first level first."

Immediately, the sword spirit led the two of them to the stone steps behind the mountain gate.

After walking more than a thousand feet, he led the two of them into a branch road and came to the two light arrays.

Two light arrays, one extremely cold, is an ice array; An extremely hot, array of fire.

"Because the master's inheritance is the way of the sword, only the spirit sword can be used in the assessment."

The sword spirit pointed to the two formations and said to the two: "This level mainly tests your will, but it also has certain requirements for combat power......"

"There are ninety-nine Dan Pagodas in each of the two formations, and at the top of each Dan Pagoda, there is a Lingyuan Pill, but there are also phantom beasts guarding ......"

The sword spirit solemnly confessed: "You must pass through at least thirty-three Dan Pagodas and capture the Lingyuan Pill inside before you are eligible to enter the second level." ”

"Understood, senpai."

Jiang Tian and the others nodded in reply, preparing to enter the light array.

"Wait a minute."

At this time, the sword spirit suddenly stopped them and said, "The evil spirit will only break through in half a month, so you have five days for each level. ”

The implication of his words was, of course, that Jiang Tian and the others should stay in the formation for as many days as possible, striving to obtain the most Lingyuan Pill and improve their cultivation.

"Got it, Senpai."

Of course, Jiang Tian and the others understood what the sword spirit meant, nodded solemnly, and stepped into the light array.

"Coax, coax!"

Jiang Tian entered the fire array, and there were red flames burning everywhere, making a coaxing sound.

"Woohoo ......"

As soon as he entered, his clothes were set on fire, emitting a scorching stench that made the corners of his mouth twitch in pain.

With the strength of the Nine Dragons Divine Body, ordinary flames couldn't burn him at all.

Obviously, these flames are some kind of spiritual flames.

He immediately destroyed the spiritual power, extinguished the fire, and then formed a spiritual membrane to protect his whole body from being burned.

"Each Dan Pagoda is about ten miles apart......"

Destroying the Broken Eye glanced forward, and he stepped forward.

Controlling the spirit membrane body protection was extremely draining, and most of the fire arrays were in unknown danger, so for the sake of insurance, he did not use his technique.

In his previous life, he had experienced too many similar tests, and he knew that the further he went, the more difficult it became, of course, he had to try to preserve his strength in case of accidents.

"Heartfire!"

At first, he could move forward easily, but after walking forward for half a mile, he suddenly showed a look of pain.

Because I don't know when it began, his soul was burning like a flame, and it was in severe pain.

In the fire array, there is a heart flame that can directly incinerate the soul.

"In the outside world, it's hard to find a wisp of heartfire, and it's all over the place, it's really a big deal!"

Forcibly endure the pain, destroy the Nine Turns Soul Refining Technique, turn the soul power into a soul armor, and protect the soul, Jiang Tian couldn't help but sigh secretly.

The background of the Martial Saint is really not something that ordinary people can imagine.

"Although you know how to cultivate the soul and can isolate the heart flame, but to break through the third level, you have to pass at least fifty Dan Pagodas, I don't know how far you can persevere?"

Outside the fire array, the sword spirit looked at Jiang Tian's back and thought silently in his heart.

The fire array is divided into three stages, each stage is thirty-three Dan Towers, and the difficulty of each stage is different.

In the first stage, each time you pass through a Dan Tower, the power of the fire array increases by one percent.

In the second stage, each time you pass through a Dan Tower, the power of the fire array increases by 30%.

In the third stage, each time you pass through a Dan Tower, the power of the fire array doubles.

By the last few Dan Towers, the power of the fire array was more than forty times stronger than it was now.

He has guarded the Heavenly Sword Palace for 30,000 years, and there are no less than 10,000 young people who come to participate in the assessment.

So far, no one has been able to break into the ninety Dan Pagodas.

There are only a handful of people who can break into the fifty Dan Towers, all of them are the cultivation of the extreme realm of military generals, and they are extremely strong-willed.

Although Jiang Tian has an extraordinary physique, can he persist in this step of cultivation as a martial artist?

He had to worry about that.

Jiang Tian didn't know what Sword Spirit thought.

He carefully guarded his body and soul, and walked forward slowly but surely.

About two quarters of an hour later, he came to the bottom of the first Danta.

"Roar!"

A two-story tall fire ape leaped down from the top of the Dan Tower, and landed in front of him with a hideous face.
