Liang Yan observed carefully for a moment and found that there was a dark hole in the 'spiritual source', like a bottomless abyss, which was constantly eroding the power of laws in the 'spiritual source'.

"This is..."The Lightless Sutra"!"

Liang Yan recognized the origin of the black hole. Luo Qing had used a similar method back then, but it was far inferior to the black hole here. The two were very different, and it was impossible to tell the truth.

After a while, the spiritual thoughts retreated from Ning Bugui's body.

From the beginning to the end, Ning Bugui was not at all wary. It was obvious that he had complete trust in Liang Yan, or in other words, complete trust in the results of his deduction.

"Master Ning Gu, from what I have seen, you were injured by the "Lightless Sutra". This magical power is extremely weird. The black hole coexists with your 'spiritual source', and ordinary methods cannot get rid of it at all.

"Liang Yan said slowly.

"You are right."

Ning Bugui sighed and said: "In the entire Yongye City, apart from the old city lord Qi, there are only two sub-sages like me and Feng Wujiu who are qualified to practice the "Lightless Sutra", but neither of us has completed the practice.

, each only had half of the sutra. The reason why Feng Wujiu didn't kill me immediately in Suixu Mountain back then was because he wanted to force me to hand over the other half of the "August Sutra". Unfortunately, his cleverness was mistaken for his cleverness, and he was eventually killed.

I escaped."

When Liang Yan heard this, he understood in his heart.

"If you were given the other half of the "Lightless Sutra", could you deduce the means to repair the injuries of the "Lingyuan" by yourself?"

"This... I'm not sure, but I can give it a try."

After hearing this, Liang Yan did not hesitate and took out a black jade pendant from the storage ring and placed it in front of Ning Bugui.

The moment Ning Bugui saw the jade pendant, there was a complicated look in his eyes.

He took the jade pendant in his hand, rubbed it carefully for a moment, and sighed softly: "It is indeed the 'Zhantai Jade' of the old city lord. He never leaves this jade. Forgive me for asking, why did he give this jade pendant to me?"

And you?"

"Because he made a deal with me and asked me to let Luo Qing go." Liang Yan told the truth without hesitation.

After hearing this, Ning Bugui nodded.

"Thank you for being honest, little friend. It seems that the old city lord is safe for the time being. There is indeed a cooperative relationship between him and Luo Qing."

After saying that, he held the black jade in his hand, released his spiritual consciousness, entered the inside of the black jade, and looked at it carefully.

In the thatched cottage, there are sandalwood birds.

After a long time, Ning Bugui opened his eyes and said slowly: "It is indeed the complete copy of "The Lightless Sutra". The magical powers and spells used by Feng Wujiu are all recorded in it. After studying for a while, I may be able to

Find a way to repair the damage.”

Having said this, he stood up from the stone table and bowed deeply to Liang Yan.

"Thank you for the book, little friend. I have been trapped in the sub-sage realm for many years and have long been discouraged. Fortunately, you, the destined person, appeared, otherwise I would not see any hope in this life..."

"The owner of the valley doesn't need to be polite."

Liang Yan waved his hand and said with a smile: "Back then, you taught me the "Shadowless Sword Sutra" and helped me create something from nothing. Now that Liang has given me the book, he is reciprocating the favor."

"Hahaha!"

As soon as he finished speaking, Ning Bugui burst out laughing: "Good boy, I really saw the right person!"

His smile comes from the heart and looks very happy.

After laughing for a while, Ning Bugui looked at Liang Yan again, with piercing eyes, and asked: "Liang Yan, have you practiced the techniques in the "Lightless Sutra" in these years?"

After hearing this, Liang Yan frowned and said: "To be honest, Liang did practice for a period of time, but the scriptures in it are obscure and difficult to understand. After so many years, I have only understood about 20% of them. Many profound and mysterious things are still

I know nothing."

"normal."

Ning Bugui touched his chin and said: "The "Lightless Sutra" is the inherited treasure of Yongye City. Feng Wujiu and I each learned half of it, and we have already reached the sub-sage realm. I have studied this half of the technique.

After a lifetime, you can understand 20% without any guidance, which is actually a rare understanding in the world."

Having said this, he paused for a moment and then continued: "Fellow Taoist Liang, if you don't give up, are you willing to stay in the 'Evil Medicine Valley' for a few years? How about you and I study the "Abyss of Light" together and seek the truth together?"

After hearing this, Liang Yan only hesitated for a moment before nodding in agreement.

Just kidding, would he refuse to agree to such a good thing?

Ning Bugui said that he would participate in the research together, which was purely to give him face. You must know that this person has reached Yasheng and has been practicing the "Augury Sutra" for thousands of years. There is no need for people to participate in the research together. It is purely because he wants to

Give Liang Yan some guidance and let him practice the "Lightless Sutra" in the shortest possible time!

"Thanks to the Valley Master's kindness, how dare Liang refuse?"

The two looked at each other and smiled, feeling extremely happy in their hearts.

........

After reaching an agreement, Liang Yan settled down in the Valley of Evil Doctors.

While he and Ning Bugui were studying the "Wu Guang Sutra", he was also waiting for news about Wu Xin.

During this period of time, Ning Bugui taught everything he had to offer without hiding anything for himself. Liang Yan was not bad at understanding at first. He immediately woke up to many of the obscure and difficult things he had learned before.

Came over.

In less than half a year, Liang Yan had integrated the "Lightless Sutra" and started practicing it.

At the same time, he was also helping Ning Bugui diagnose and treat his injuries.

There are many unique medical skills in the "Shennong Emperor Jing". Liang Yan had no one try them before, but now they are all used on Ning Bugui. Although there are occasional mistakes, Ning Bugui has extremely strong resistance and can be regarded as a medical expert.

An object that cannot be cured.

After repeated trials, Liang Yan finally found two ways to repair the injury.

Of course, these two methods are based on the "Aluminum Sutra". You need to practice the entire "Alumina Sutra" before you can start treatment. Moreover, the repair speed is not fast. If you want to completely eradicate it, you must spend a lot of time.

A long time.

Although both methods had many flaws, they helped Ning Bugui find a direction. Ning Bugui didn't complain at all, but was even more grateful to Liang Yan.

Time flies, time flies.

The two of them studied medical skills in the valley and sat and discussed. Seven years passed in the blink of an eye.

On this day, the wind was gentle and sunny, and the sky was clear.

In the Evil Doctor Valley, a seemingly ordinary smooth mountain wall hides a strange cave.

There is no light in the cave, but the faint sound of rhythmic breathing can be heard.

Suddenly, a whirlpool appeared in the middle of the cave.

All the surrounding darkness surged toward the center of the whirlpool like a tide, making the darkness there darker and darker, like a bottomless abyss. Even if there was more light, it would not be able to illuminate the whirlpool, and it would eventually be swallowed up by darkness...

...

The vortex does not rotate very fast, but every time it rotates, it shrinks by one point. From the initial ten feet in radius, it quickly shrinks to three inches.

The small three-inch whirlpool was extremely dark.

It seems that all laws will disappear into nothingness when they reach this point...

But it was such a terrifying black vortex that finally landed in the palm of a hand.

In the depths of darkness, the owner of that palm is looming.

He was tall and broad-shouldered. He was sitting cross-legged, letting the endless darkness fall from the top of the cave and pour on his head.

This person seems to be sitting under a waterfall, except that what flows in the waterfall is not river water, but darkness...

"It's done!"

In the dead silence of the cave, the man's excited voice rang out.

The man lowered his head and looked at the black vortex in his hand, and suddenly tapped the gourd on his waist, and a sword light came out, hanging in the sky above the cave.

The man raised his sleeves again, and the dark whirlpool flew away and came to the sky above the cave, actually merging with the sword light.

After the fusion, the sword light turned into a deep darkness, which seemed to be able to swallow up all the surrounding light, with a deathly chilling aura.

"go!"

With a low shout, black sword light rose into the sky and slashed towards the mountain wall in front of him.

There was no sound at all. The tall mountain wall just disappeared without a sound, as if it had been swallowed up by the edge of the flying sword!

A huge black hole appeared on the mountain peak, and then a black sword light flew out.

Wherever this sword light passes, everything will wither and no life will survive!

Even those bright sunshine cannot escape the poisonous hand. Everything stabbed by the sword energy or covered by the sword light will become dark, as if falling into a bottomless abyss.

The sword light galloped across the valley, but in just a few breaths, half of the valley had been transformed into chaotic darkness.

At this time, an old voice came from a certain peak in the valley:

"Okay, okay, brat, if you keep doing this, my evil doctor valley will be gone!"

Hearing this sound, a chuckle came from the cave.
