Douluo Continent: Starting with the Burning Blade, he was then entangled with Ma Xiaotao.

As school let out, the classroom was bustling with students.

Lin Feng was packing his schoolbag when he suddenly heard a familiar call coming from the front door: "Xiao Feng! Over here! Come out quickly!"

He looked up and saw Ma Xiaotao waving vigorously at him, her red hair standing out in the crowd.

"Sister Tao, you seem to be in a good mood today? What brings you here to pick me up from school in person?" Lin Feng quickly squeezed through the crowd, not forgetting to tease her.

"I have some amazing news to tell you! Come with me, let's go to my dorm first." Ma Xiaotao smiled and grabbed his hand.

"Shh, keep your voice down," Lin Feng whispered. "If your classmates hear you, it will have a bad influence on you."

"What are you afraid of? You're my most precious junior brother. If anyone dares to gossip, I'll roast them alive!" Ma Xiaotao said nonchalantly, flame wings already unfurling from her back. "Hold on tight!"

Before Lin Feng could react, she had already taken him and leaped out of the corridor, causing the freshmen downstairs to look up.

"Wow, what an overwhelming aura... I'm referring to her martial spirit! Could she be a senior from the inner court?"

"I'm not sure, but it seems like she dragged Lin Feng from Class 9 away? That guy's got some luck with women..."

In no time at all, Ma Xiaotao had carried Lin Feng to her single dormitory room like a chick.

"Sister Tao, can we walk next time? I'm a little dizzy... in the car." Lin Feng steadied himself by holding onto the wall.

"I'm happy today, so I'll do whatever you say next time." She replied with a smile, and suddenly released her martial spirit without warning.

One yellow, one purple...

Wait, what about the second spirit ring?!

Lin Feng immediately noticed something was wrong: "What happened to your second spirit ring...?"

"Junior Brother has a good eye." Ma Xiaotao proudly raised her chin. "That's right, it's a thousand-year soul ring."

"But wasn't it a hundred-year soul ring this morning? What's going on?" Lin Feng had already guessed seven or eight parts of the reason, and it must be related to his Burning Technique.

"This is the good news I wanted to tell you." Ma Xiaotao happily leaned closer, "The Phoenix Fire that you fed back after absorbing my Evil Fire was exceptionally pure, which actually increased the age of my Soul Ring. I didn't even notice it at first, until this second Soul Ring, which is over eight hundred years old, broke through to a thousand years old."

Lin Feng pondered, "It seems similar to my first spirit ring; both were enhanced after absorbing flames."

Ma Xiaotao looked at Lin Feng with sparkling eyes, like a kitten that had discovered a treasure: "Yes, so we'll have to work hard for you, Junior Brother. Let's improve together, the more the better."

"No! I'm still young..." Lin Feng seemed to have already foreseen the bitter days of dual cultivation in the future, where he would regularly hand over flames.

"Since you're coming to my dorm today," Ma Xiaotao's eyes shone even brighter, "let's strike while the iron is hot and cultivate together in the hot springs. My bathtub is quite big, no less than that of Sea God Lake."

"Sister Tao, no!"

"Come on, let your senior sister see your progress!"

The bathroom was sometimes steaming hot, sometimes icy cold, with light and shadow intertwined, making it impossible to see what was inside.

One hour later.

Lin Feng emerged from the bathroom, supporting his lower back.

After absorbing the essence of the Xuanbing Spirit Flame, his Yellow-Rank Burning Technique evolved into the Profound-Rank.

However, it seems too difficult for the Profound Rank Burning Technique to devour the Phoenix Evil Fire's origin at present; it will have to wait until it evolves to the Earth Rank in the future.

He still had to endure the hardships of dual cultivation before that, as he had become completely dependent on Ma Xiaotao.

Upgrading your spirit rings is good, but your life is more important.

While Ma Xiaotao was still busy getting ready, Lin Feng fled the hideout overnight.

The following morning, at Mingfeng Courtyard on Poseidon Island.

"Teacher, may I request a detailed list of all fire-attribute soul masters in the academy?" Lin Feng asked respectfully.

Yan Shaozhe put down the book in his hand and looked at him with a hint of doubt: "Why do you suddenly want this?"

Lin Feng recounted in detail the causes and consequences of Ma Xiaotao's breakthrough in spirit rings.

Upon hearing this, Yan Shaozhe chuckled and shook his head: "This girl, she didn't even come to tell me about something so important. It seems that in her heart, you, her junior brother, are even more important than your master."

"Teacher, you're joking," Lin Feng quickly said. "I've only known her for a few days, how could I compare to you?"

"So, what's your intention in asking for the list?"

"This disciple wishes to seek out high-level fire-attribute soul masters, and attempt to cultivate together by absorbing and transforming their flames, thus advancing together in our cultivation."

"Good ambition," Yan Shaozhe nodded approvingly, stood up and pulled out two thick books from the bookshelf, "and take this 'Illustrated Compendium of Fire-Attribute Soul Beasts' for reference as well."

"Thank you, teacher." Lin Feng accepted it with both hands.

However, he already had his own considerations, namely that the fire of a Soul Master far surpasses the fire of a Soul Beast.

After all, people can cultivate together every day and improve together, but it is difficult to find the same kind of soul beast every day, let alone hunt it.

While flipping through the list, a familiar name came into view: "Wu Feng, freshman class nine, twelve years old, martial spirit red dragon..."

"Teacher, may I copy this list?"

"No need for trouble, just take it and use it, just don't share it with others."

"I understand. If there are no further instructions, I will take my leave."

"Go on... wait a minute," Yan Shaozhe suddenly called out to him, a meaningful smile flashing in his eyes, "There's one person missing from this list."

"Who is the teacher?"

"It is I, your master," he said, standing with his hands behind his back, his expression gentle. "My Radiant Phoenix Martial Soul possesses both light and fire attributes. If needed, you may come to me for assistance."

Lin Feng was taken aback, and quickly waved his hand: "With my current cultivation level, how dare I devour Master's flames? That would only be like a moth drawn to a flame..."

His current Profound-Rank Burning Technique can't even devour the Phoenix Evil Flame's essence, so how could he dare to covet Yan Shaozhe, a Super Douluo...

"It's alright, there's plenty of time in the future." Yan Shaozhe laughed heartily, watching his disciple's departing figure with anticipation in his eyes.

For several days in a row, Lin Feng visited several fire-attribute soul masters according to the list, but to no avail.

Although their flames each had their own unique characteristics, none of them had been able to condense their origin, let alone the rudimentary form of it, making it difficult to meet the needs of the Burning Technique cultivation.

Powerful high-level fire-attribute martial soul masters like Ma Xiaotao and Yan Shaozhe are always a minority, and are hard to come by.

"How could I forget this tomboy? He's so close yet so far away."

Just when Lin Feng was about to give up hope, he suddenly slapped his forehead and remembered Wu Feng, who sat in front of him.

Everything done before was simply taking the long way around.

Wu Feng's martial soul, the Red Dragon, is a top-tier fire-attribute sub-dragon. If all goes well, it should be able to nurture the Red Dragon Heart Flame.

This fire is extremely fierce and domineering, with astonishing destructive power, making it one of the top-tier beast fires.

In the special freshman training ground set up by Shrek Academy, Lin Feng found Wu Feng, who was cultivating alone.

With just a slight activation of the Burning Technique, Lin Feng discovered the rudimentary form of the Crimson Dragon Heart Flame within her heart.

"Let's make a deal," Lin Feng said bluntly.

"I'm busy." Wu Feng raised her red eyes and gave him a cold glance.

"I can purify your Red Dragon Heart Flame," Lin Feng calmly stated, giving Wu Feng a reason he couldn't refuse, "to elevate the quality of your Martial Soul to a higher level."

"What did you say?!" Wu Feng quickly stood up, unable to believe his ears.
