Chapter 86 Reunion with Xiao Yan, The Theory of Spiritual Veins

Soon after,

On the plaza where the selection competition for the inner and outer courtyards took place.

Around the vast square, tiered stands rose up, and the stone steps were filled with students who came to watch the game.

The entire venue was designed ingeniously, allowing everyone to have a clear view of the competition from any seat.

At this moment, two figures were flashing past each other at an astonishing speed. The aftershocks of their battle auras caused by each collision drew gasps from the audience in the stands.

One of the young men in blue wielded a long steel sword, its blade wreathed in pale blue battle aura, each swing bringing with it a chilling aura.

His opponent, the young man in black robes carrying a heavy black ruler, moved through the sword light with unpredictable movements.

"What a quick movement!"

In the stands, a freshman couldn't help but exclaim.

"That should be a high-level Xuan-rank movement technique..."

The senior student beside him explained, "This newcomer is very strong. He has mastered that fighting technique to a very high level. Aizen is likely to lose..."

Before the words were even finished, the situation on the field suddenly changed. The black-robed youth, who had been dodging, abruptly stopped, his right fist wreathed in earthy yellow flames, with what seemed like a howling wind, before he unleashed a powerful punch!
"Baji collapse!"

"boom!"

The air distorted wherever the fist struck. The young man in blue hastily parried with his sword, but he and his sword were sent flying backward, leaving a trail more than ten meters long on the bluestone ground before he could barely regain his footing.

"Senior, I'm grateful for your kindness."

Xiao Yan put down his fist and stood up, a humble smile on his lips.

The young man in blue wiped the blood from the corner of his mouth and said with a wry smile, "What a dark horse. The force of that punch, even a Seven-Star Grandmaster probably couldn't withstand it."

He gave Xiao Yan a deep look, clasped his hands in a fist and said, "I accept my defeat wholeheartedly."

Having said that, he turned and left with a carefree air.

"Xiao Yan wins this round!"

As soon as the referee announced the decision, the entire stands erupted in cheers. A torrent of chatter followed:

"This is the third time already!"

"I heard he's only seventeen?"

"That heavy black ruler was never used from beginning to end..."

"To be this strong after taking a year off is unbelievable!"

Amidst the clamor of the crowd, Xiao Yan let out a long sigh, a relaxed smile appearing on his face.

Suddenly, as if sensing something, he abruptly looked up at a certain spot in the stands.

A familiar figure in a green robe stood there smiling, gazing at him with gentle eyes.

"Brother Lu!"

Xiao Yan's eyes lit up with surprise, and his voice was filled with the joy of a long-awaited reunion.

This shout immediately drew everyone's attention to the figure in the green robe.

"That's... Elder Lu from the Inner Court?"

"This aura... Elder Lu just became an elder, how come he seems stronger than most elders?"

A chorus of gasps and exclamations erupted from the stands.

The old man's voice echoed in Xiao Yan's heart: "Little Yan, Lu is even stronger than we expected. He actually possesses the aura of three different flames. What's even more astonishing is that his cultivation has already reached the six-star Dou Wang level..."

"To go from a two-star Dou Ling to a six-star Dou Wang in just one year—such a cultivation speed is truly astonishing..."

At this moment, the referee announced loudly: "Today's selection competition is now over! We will continue tomorrow!"

Xiao Yan hurried forward, leaping onto the arena in a few strides and arriving in front of Lu Yu. The two exchanged a smile, and without a word, they walked towards the edge of the arena in perfect unison.

"It's been a year since I last saw you, and you've grown quite a bit taller."

Lu Yu looked Xiao Yan up and down, his eyes full of satisfaction, and said, "You have now reached the level of a five-star Great Dou Master and have even subdued the Wind Fury Dragon Flame. It seems that you have gained a lot from this training trip."

Xiao Yan chuckled and was about to speak when he saw Lu Yu suddenly take out an exquisitely crafted jade box from his storage ring and casually toss it over.

"What is this?"

Xiao Yan caught the jade box steadily, a look of doubt on his face.

"It's just a small gift." Lu Yu explained casually, "It contains a spiritual item called the Crimson Flame Flower. This item is very effective in breaking through bottlenecks and stabilizing one's foundation. It will be even more effective when you take it when you attempt to break through to the Dou Ling realm."

"Hey, how embarrassing..."

Xiao Yan's eyes lit up instantly, and he happily put the gift away.

After a moment's hesitation, he took out a crystal-clear jade bottle from his storage ring. Inside the bottle were several jade-like leaves with naturally formed dragon scale patterns on their surface, which shimmered with an unusual luster in the sunlight.

“Brother Lu, this is the ‘Wind Dragon Scale Leaf’ that I found deep in the Tagor Desert.”

Xiao Yan handed the jade bottle to Lu Yu and patiently explained, "They grow in the oases where the Wind Fury Dragon Flame often appears. They are a kind of companion creature of the strange fire. Because they are nourished by the aura of the strange fire all year round, they have produced wonderful effects."

Lu Yu took the jade bottle and carefully examined the green leaves inside. Each leaf was as thin as a cicada's wing, yet exceptionally resilient, with what appeared to be a flowing blue light moving within its veins.

"interesting."

Lu Yu gently shook the jade bottle and asked with great interest, "What are the specific effects of this Wind Dragon Scale Leaf?"

Xiao Yan explained earnestly, "My teacher said that as long as you carry this item with you, it can not only resist the desert heat, but also greatly benefit those who cultivate wind-attribute techniques."

"Moreover, if one piece is added when refining wind-attribute pills, it can significantly increase the success rate of pill formation."

He smiled somewhat sheepishly and said, "Besides this, I don't have anything else I can offer..."

At this moment, Yao Lao's voice rang in Lu Yu's mind: "This kid is quite generous. Lu boy, don't underestimate the Wind Dragon Scale Leaf just because it's not as practical as the Crimson Flame Flower. Its rarity is far greater. For wind-attribute Dou Wang and Dou Huang powerhouses, this is a treasure that is priceless."

Lu Yu nodded in understanding and carefully put the jade bottle into his storage ring.

He reached out and patted Xiao Yan on the shoulder, his tone tinged with satisfaction, and said, "It seems this trip to the desert has been very rewarding for you."

"Come on, let's find a quiet place and have a good chat about what's happened this past year."

……

Soon after,

In the outer courtyard, beneath a towering tree, before a stone table, Lu Yu and Xiao Yan sat facing each other.

"You mean Queen Medusa has broken through to the Dou Zong level, but her condition is somewhat unusual?"

Lu Yu raised an eyebrow and asked.

"Yes."

Xiao Yan nodded and lowered his voice, saying, "I didn't have time to look closely because of the emergency, but my teacher said that there seemed to be another soul inside her vying for control of her body..."

"Later, I encountered the raging dragon flames. In order to get rid of that woman and also to catch up with that strange fire, my teacher taught me a set of high-level Xuan-rank movement techniques..."

"After refining the strange fire and creating the strange fire spiritual vein..."

At this point, a hint of excitement flashed in Xiao Yan's eyes as he said, "Brother Lu, do you know what I've discovered?"

"Oh? What did you find?" Lu Yu raised an eyebrow and asked curiously.

"Once this spiritual vein was formed, I felt a significant increase in my affinity with the fire and wind energies of heaven and earth. These two energies seemed to spontaneously converge around me without any need for guidance..."

"and many more……"

Lu Yu suddenly interjected, "What level of spiritual vein did you create?"

"A second-tier connection, Brother Lu, what's wrong?"

Xiao Yan asked with some confusion.

"Level two?" A thoughtful look flashed in Lu Yu's eyes.

According to the method of shaping the Different Flame Spirit Vein, the quality of the Different Flame Spirit Vein largely depends on the potential of the Different Flame and the strength of its source power.

Generally speaking, the better the characteristics of a strange fire, the greater its potential, and the longer it has been around, the higher the grade of the spiritual vein it creates.

According to his estimate, most of the spiritual veins created by the strange fires ranked outside the top ten on the list are probably human connections.

But don't underestimate this small connection. In this vast world, those who possess spiritual veins are one in ten thousand.

A single connection can give someone the potential to reach the pinnacle of the Three Heavens Realm, which, in the context of the Dou Qi Continent, would be equivalent to the peak of the Dou Zun Realm.

If it is a level-earth spiritual vein, as long as the cultivator does not die prematurely, they are guaranteed to reach the Supreme Realm.

As for the Heavenly-level spiritual veins, they are even more terrifying, guaranteeing at least the Earthly Sovereign realm. Those with extraordinary luck among them may even have a 10-20% chance of entering the ranks of Heavenly Sovereigns.

As for the legendary divine veins, the probability of their possessors breaking through to the Heavenly Sovereign level is at least over 50%. If they can be nurtured by a super power with a Heavenly Sovereign overseeing them, this probability can increase to 70% or 80%.

If one is born into one of the top super powers with a Saint-grade Heavenly Sovereign in charge, the probability can be increased to 90%!
It can be said that as long as the owner of a divine vein does not die young, they are guaranteed to be a Heavenly Sovereign, destined to stand at the pinnacle of the Great Thousand Worlds.
