Chapter 66 Qinglin's Choice of Natal Gu
"It's Qinglin's voice..."

Little Fairy Doctor gently tugged at Lu Yu's sleeve, her voice filled with undisguised joy.

The two looked in the direction of the sound and saw Qinglin standing on tiptoe on the arena stage, waving her small hands high. Her bright green eyes were striking, her cheeks flushed with excitement, and the ribbon binding her hair fluttered merrily with her movements.

"Young master, it's Sister Little Fairy Doctor!"

Qinglin's clear voice pierced through the noisy training ground as she announced, "I just won the match!"

Lu Yu and Little Fairy Doctor exchanged a smile and walked towards the arena.

As they approached, Qinglin had already gracefully jumped off the arena, her little face flushed and her eyes full of joy. She happily said, "Young Master, what brings you here?"

"Our training in the inner courtyard has come to a temporary halt, so I've come to see how Qinglin is progressing."

Lu Yu smiled gently.

Little Fairy Doctor took out a handkerchief from her sleeve and gently wiped the sweat from Qinglin's forehead, saying, "I heard you've been working very hard lately."

The three of them found a secluded spot under a large tree and sat down. Lu Yu took out a blue jade slip from his storage ring, his expression becoming serious, and said, "Qinglin, the main reason I came here this time is to give this to you."

The four ancient characters "御虫心经" on the jade slip gleamed faintly in the sunlight.

Lu Yu explained, "This is a unique cultivation technique that focuses on controlling various strange insects and snakes in the world, which is perfect for your physique."

Qinglin carefully took the jade slip, her green eyes sparkling with curiosity and anticipation.

"Take a look first, and you can ask me if you don't understand anything."

Lu Yu said seriously that he had already memorized this "Insect Control Manual" by heart, and what he was giving to Qing Lin was just a copy.

While I wouldn't presume to have grasped all the mysteries within, I am more than capable of guiding Qinglin.

After a while,

Qinglin put down the jade slip, her eyes sparkling, and asked, "Young Master, may I refine Little Red into my natal Gu?"

"Xiaohong?"

Lu Yu was taken aback and said with some confusion.

"It's that two-headed fire spirit snake you caught for Qinglin before..."

Little Fairy Doctor rolled her eyes at him and gave him a helpless reminder.

"Such a name?"

Lu Yu's lips twitched, and he silently complained before shaking his head and saying, "I don't recommend using it as your natal Gu. A natal Gu and its master complement each other; a breakthrough in either one can boost the other."

"That two-headed fire spirit snake has limited aptitude; it probably won't even be able to break through to the seventh rank. If you use it as your natal Gu, it will actually hinder you when you reach the Dou Zong realm."

He added solemnly, "With your talent, you will at least reach the Dou Sheng level in the future. You must choose a rare species with the potential to advance to the ninth rank for your natal Gu, otherwise you will regret it later."

"In that case, when you advance to the Dou Sheng realm in the future, your natal Gu will also advance to a ninth-tier magical beast, which is much stronger than an ordinary Dou Sheng."

Upon hearing this, Qing Lin was first taken aback, then said incredulously, "But young master, let alone whether I can break through to the Dou Sheng realm, the key question is, where are we going to find a ninth-tier magical beast cub? This is too far-fetched!"

“I have made preparations for this matter. For now, you should study the other secret techniques in the Insect Control Manual.”

"There's no need to worry about your natal Gu."

Lu Yu shook his head and said with a firm expression.

In the Dou Qi Continent, the only magical beasts that can grow to the ninth rank are snakes, and there are only a few types. The one closest to you and the easiest to get your hands on is Queen Medusa.

Although the Snake-Man Queen may have already broken through to the Dou Zong level, making her difficult to target, what he truly coveted was not her physical form, but the Seven-Colored Devouring Python Soul that Queen Medusa had nurtured during her evolution.

Although the Insect Control Manual he obtained did not contain any heaven-defying supernatural powers such as the Life-Saving and Calamity-Avoiding Technique, it did contain a method for reshaping the physical body.

Since the combat method of a Spirit Insect Master mainly involves manipulating spirit insects, it is common for the spirit insects' physical bodies to be damaged in some intense battles.

In order not to lose some spirit insects with special abilities and extraordinary bloodlines, this method of reshaping the physical body came into being.

However, to create its physical body, in addition to the soul of the spirit insect, it also requires the essence blood of the spirit insect, as well as a rare item called the Azure Jade Lotus Root, which is not easy.

"Okay, I understand!"

Qinglin nodded obediently, then blinked her big, bright green eyes and asked expectantly, "How long will you and Little Fairy Doctor stay in the outer courtyard this time, young master?"

Lu Yu was taken aback, and the farewell words he was about to say suddenly stopped. Looking at the expectant look in the little girl's eyes, he hesitated for a moment and said gently, "We will stay with you in the outer courtyard for half a month. During this time, we can properly guide your practical combat skills."

As he spoke, he gently patted Qinglin's shoulder and said, "Now that you are a Battle Master, it's time to start systematically training your combat skills. I will personally spar with you for the next two weeks."

Little Fairy Doctor added softly, "I will also teach you some techniques for using and detoxifying poisons. Although you may not need them in the future, it's always good to learn more."

Upon hearing this, Qinglin's eyes immediately lit up with a dazzling light, and she jumped up like a joyful little deer, exclaiming happily, "Really? That's wonderful! I'll go ask Instructor Ruolin for leave right away!"

Before she could finish speaking, she turned and ran outside.

"and many more."

Lu Yu smiled and stopped her, saying, "First, sort out the parts of the 'Insect Control Heart Sutra' that you don't understand, and we'll address them one by one."

……

Half a month later,

In a dense forest in the outer courtyard.

A man in a blue robe stood with his hands behind his back, his movements as graceful as the wind, easily dodging every attack from the girl in green.

Fine beads of sweat had appeared on Qinglin's forehead, but he still gritted his teeth and quickly formed hand seals. A green light blade shot out from his sleeve.

"Not bad, the duration of the combat technique is quite good..."

Lu Yu nodded slightly, his figure swaying slightly as he dodged the light blade, and said, "But you have to be careful to change your rhythm. Attacks that are too predictable are easy to anticipate."

With that, he lightly touched the ground with his toes, and a blur shot out, striking towards Qinglin like a streak of light.

Qinglin hastily formed hand seals, and a green protective shield instantly took shape. With a muffled "bang," the shield trembled violently.

Lu Yu stopped what he was doing, looked at the panting girl, and shook his head, saying, "Let's call it a day..."

Before he could finish speaking, he suddenly sensed something and turned to look.

Not far away, beneath an ancient tree, two figures had been standing silently for some time. One carried a heavy black spear on his shoulder, his aura as imposing as a mountain; the other was dressed in snow-white robes, with a green sword hanging at his waist.

It was Liu Qing and Lin Xiuya, whom they had met briefly a few months ago.

"Junior Brother Lu, we've been looking for you everywhere."

Lin Xiuya smiled gently, his white robes fluttering in the wind, and said softly, "It has been several months since we parted ways at the arena."

Liu Qing pulled out a Fire Energy Card and tossed it to Lu Yu, saying, "I heard you've reached the Seven-Star Battle Spirit level. Let's have a good fight. Here's a thousand Fire Energy Points as a prize."

Lu Yu caught the fire energy card, a playful smile curving his lips. "You two seniors are certainly well-informed. However..."

"This small prize is hardly worthy of the value of my 'Burning Heaven Finger', is it?"

"Ok?"

Liu Qing frowned, displeased, and said, "You little brat, trying to raise the price on the spot?"

"I mean--"

Lu Yu held up two fingers and shook them, saying, "It costs more."

Lin Xiuya couldn't help but chuckle, then took out another fire energy card from his sleeve and said, "Junior brother certainly knows how to do business. How about adding another thousand?"

"How can this be so embarrassing..."

Lu Yu verbally declined, but his hand had already reached out honestly.

Unexpectedly, Lin Xiuya flipped his wrist, and the fire energy card spun nimbly between his fingers. A cunning glint flashed in his eyes as he said, "This thousand can only be given after you defeat the two of us."

"If we lose, the previous thousand will be returned in full."

"make a deal!"

Lu Yu readily agreed, his eyes gleaming with growing fighting spirit.

Is that two thousand fire points?

Those are the resources I need to break through to the Dou Wang level!
