Hearing Bai Zhenzhen’s curious inquiry, Zhang Yu immediately recounted the story of Le Mulan and the potion.

Finally, he said with a helpless expression, “I don’t know if there are any side effects to the potion from Le Mulan. What if the tuition fees I earn aren’t even enough to cover the medical expenses?”

Bai Zhenzhen’s eyes sparkled as she said, “You said her sweat can restore physical strength, excite the nerves, stimulate mana, and according to her, even heal injuries…”

“This is a panacea!”

“Bring me some back next time so I can try it. I have a high drug tolerance and I’m not afraid of side effects.”

Zhang Yu realized that even though he had been in Kunxu for a while, he still felt somewhat out of place at times.

For example, with the idea of collecting sweat from rich people, even if he wanted to make up his mind, he ultimately couldn’t convince himself.

Seeing Zhang Yu not responding, Bai Zhenzhen said, “Then ask Le Mulan when she’s going to invite us both for sparring. Didn’t she say she’d consider it during the martial arts competition?”

Bai Zhenzhen thought to herself that since Zhang Yu wasn’t willing, she would collect the sweat herself.

Zhang Yu casually said, “She said she needs to adapt before she can take on both of us at once. I don’t know what she needs to adapt to.”

“I already made her sweat all over when I fought her alone. How can she adapt to fighting both of us at once?”

As he spoke, Zhang Yu glanced at Bai Zhenzhen’s legs, at the skin exposed to the air, and saw that the scars from the martial arts competition had disappeared.

Looking at the smooth, porcelain-like skin, Zhang Yu smiled and said, “Ah Zhen, the scars on your body are gone! Now you don’t have to worry about them breaking open when you go all out.”

Bai Zhenzhen smiled and nodded, pulling up her sleeve to show off the newly repaired skin on her arm. “How do you think it looks? I think it’s okay, basically no different from my old skin.”

Zhang Yu looked at the soft, white skin and was about to compliment it when he suddenly saw a “Heart Creation Medical” logo and asked, puzzled, “What’s this?”

Bai Zhenzhen said nonchalantly, “It’s an advertisement implanted during the surgery. You either become a gold member of the hospital to avoid ads, or you spend an extra two thousand to remove it.”

“I’m not spending that money, my metabolism is fast enough, it’ll be gone in a few weeks.”

Hearing this, Zhang Yu nodded. There was no need to pay to remove an advertisement that would disappear on its own.

Zhang Yu then asked, “How much was it? I’ll transfer the money to you, I’ll reimburse you.”

Bai Zhenzhen showed her electronic bill and said, “After the discounts, they quoted me 38,888 yuan and gave me a free physical.”

After transferring the money to Bai Zhenzhen, Zhang Yu’s savings dropped to just over 170,000, making him sigh at how quickly money disappeared.

Bai Zhenzhen cheered and hugged Zhang Yu from behind, pressing against him. “A reward for you, Yu-zi.”

Feeling the True Spirit Root enter his Dantian and spiritual essence surging from all directions, Zhang Yu couldn’t help but groan in comfort.

Bai Zhenzhen ran to the side and said, “You cultivate for a while, I’ll leave after I finish my makeup.”

Bai Zhenzhen began to put on wigs, tattoo stickers, pads… one by one, preparing for her part-time job in the dark tutoring world.

After the spirit root entered his body, Zhang Yu once again activated the Great Sun Qi Sea technique.

At first, nothing happened, but after a while, he felt that the True Spirit Root seemed to be adapting to the Great Sun Qi Sea technique, subtly helping Zhang Yu collect light.

However, after Zhang Yu completed one cycle of breathing, Bai Zhenzhen finished her disguise, and Zhang Yu could only try using the True Spirit Root to assist the Great Sun Qi Sea again later in the park.

In the blink of an eye, three hours passed.

Beside the small lake in the park.

The lights from the park office building, the moonlight falling from the sky, and the streetlights nearby… strands of light were constantly absorbed by Zhang Yu, and the spiritual essence within was refined into mana.

Zhang Yu had advanced the Great Sun Qi Sea to Level 2 (11/20).

At this moment, he no longer emitted any light, but instead appeared increasingly dim in the darkness.

Under the influence of the True Spirit Root, this dimness spread from his body surface… gradually expanding to a range of dozens of centimeters around him, as if a formless shadow enveloped him.

Zhang Yu thought to himself, “Indeed, the True Spirit Root is adapting to the new technique, helping me improve the efficiency of absorbing light and collecting spiritual essence.”

Fu Ji, witnessing this scene, felt even more amazed: “Bai Zhenzhen’s evolutionary spirit root is too useful. It can change with the user’s cultivation techniques and cultivation direction, constantly adapting and evolving. It’s simply an all-purpose spirit root.”

“Now this spirit root has increased the efficiency of the Great Sun Qi Sea’s breathing by at least ten percent. If it continues to adapt, I wonder how much it will eventually improve.”

At the same time, a hint of curiosity welled up in her heart: “This spirit root is currently around the level of a Heaven Spirit Root. Will it evolve into a Divine Spirit Root in the future… or even a Celestial Spirit Root?”

Fu Ji couldn’t be sure, but she grew increasingly curious.

After all, above the Heaven Spirit Root was the military-grade Divine Spirit Root, and above the Divine Spirit Root was the Celestial Spirit Root, specially supplied to the Ten Great Sects.

Fu Ji thought to herself, “If Bai Zhenzhen’s spirit root can evolve into a Celestial Spirit Root, that would truly be immense wealth… but also an immense disaster.”

In the blink of an eye, the night passed.

Facing the morning sun, Zhang Yu carried Bai Zhenzhen on his back, running all the way from the distant suburbs towards the city center.

However, Zhang Yu had already advanced the Great Sun Qi Sea to Level 3 (14/30). Even without deliberately circulating his energy, his entire body passively absorbed light on its own.

Zhang Yu felt that the passive absorption effect of Level 3 was about thirty percent of the active absorption effect of the Great Sun Qi Sea.

He estimated that this technique, like the Stellar Qi Gathering Method, would likely have no difference between passive and active absorption effects after reaching Level 10.

At this moment, as the morning sun rose, Zhang Yu felt the strands of sunlight, like sparks of fire, being violently poured into his body. Accompanied by the unceasing circulation of the Great Sun mana, they were constantly collected into his Dantian and ultimately refined into Zhang Yu’s own mana.

As the morning sun grew brighter, Zhang Yu felt the Great Sun Qi Sea within his body circulate even more violently.
Golden Great Sun mana brought forth rolling heat, like strands of flame roaming through Zhang Yu’s body, frantically desiring and devouring the solar brilliance he had absorbed.

Zhang Yu felt his dantian was more like a small furnace, the absorption of solar light like adding fuel to the fire, burning ever brighter and constantly emitting an increasingly profound Great Sun mana.

However, Zhang Yu felt no discomfort, but rather a warm, cozy feeling, like basking in the winter sun.

He thought to himself that this Great Sun Qi Sea was indeed better suited for cultivation during the day, the efficiency being vastly superior to that of the previous night.

Behind Zhang Yu, Bai Zhenzhen exclaimed in surprise, “Yu Zi, you’re getting darker and darker.”

She saw that with the vigorous operation of the Great Sun Qi Sea, Zhang Yu seemed to be shrouded in a layer of shadow, appearing several shades darker than before.

Zhang Yu quickly looked at his body and immediately realized this.

“Crap! I’m turning into a black person!”

He thought to himself, “It’s a good thing I’m in Kunxu, otherwise, using this technique elsewhere would get me shot at every day.”

However, the Great Sun Qi Sea had its own way of eliminating anomalies. With a thought from Zhang Yu, he slightly smoothed out the Great Sun mana and reduced the effect of passive absorption, and the shadow on his body suddenly disappeared.

Bai Zhenzhen asked curiously, “If your Great Sun Qi Sea continues to upgrade, and the absorption of solar light becomes stronger, will you eventually turn completely black? Wouldn’t that be useful for concealing your identity?”

“Then, if you turn black in the future, try to see if you can evade fares, dodge surveillance, or even steal and rob…”

“Ah Zhen, you little demon… you’re going too far! Who told you that becoming black makes it easier to commit crimes?”

Zhang Yu was about to loudly rebuke her when Bai Zhenzhen said, “Oh well, forget it. Doing those things feels less profitable than underground tutoring, and you have to figure out how to pay taxes yourself, too troublesome.”

Zhang Yu couldn’t help but sigh at the fact that taxation was definitely an important factor in maintaining Kunxu’s security.

On the way back to the city, Zhang Yu’s phone vibrated. He opened it and saw that it was a message from Yu Xinghan.

Yu Xinghan: “You’re looking to rent a house?”

Zhang Yu’s heart stirred. Yu Xinghan must have seen his post on Moments about renting a house, that’s why he came to ask.

Considering that Yu Xinghan was a Golden Core disciple and held untold wealth, he probably had a vacant house to rent to him.

So Zhang Yu immediately replied: “Yes.”

Yu Xinghan: “The house I rent is a bit big, would you like to share it?”

Zhang Yu frowned and replied, “A Golden Core disciple still rents a house?”

Yu Xinghan: “Never buying a house is a principle adhered to by my lineage. Rather than spending money on a house, it’s better to invest in oneself.”

Zhang Yu thought to himself that True Person Xinghuo was indeed a poor Golden Core, a dignified Golden Core True Person couldn’t even afford a house in Songyang City on the first layer of Kunxu. Glad he didn’t join his sect in the first place.

But when he asked about the rent, which was more than 100,000 per month, Zhang Yu felt that he had been presumptuous.

So Zhang Yu replied: “I don’t like sharing a house.” He thought that by refusing Yu Xinghan, their conversation would end there.

Who knew that Yu Xinghan would send another link to a shopping platform.

Yu Xinghan: “Go in and click for me.”

Zhang Yu was slightly stunned, looked closely, and was speechless.

“Good heavens, Kunxu’s version of ‘cut a buck’, is it?”

“Isn’t Yu Xinghan a Golden Core disciple? Does he have to take advantage of even this small thing?”

Zhang Yu was too lazy to pay attention to him.

In the following day, Zhang Yu continued to receive more messages asking about renting a house.

As Zhang Yu cultivated the Great Sun Qi Sea in the sun on the rooftop, he received a rental message from Qian Shen.

It was a small apartment of more than 20 square meters under his father’s name, with a rent of 6,000 a month.

Zhang Yu was slightly tempted because this price in the city was definitely very cheap, it was Qian Shen giving him a friendship price.

While eating in the cafeteria, Zhang Yu received a message from Song Hailong.

He directly sent photos of the room, which looked much bigger than Qian Shen’s small apartment of more than 20 square meters, and the lighting was also very good, with a large balcony outside, perfect for him to cultivate the Great Sun Qi Sea.

“It’s just that there are a lot of washing machines, why are there four in the room?”

Hearing Zhang Yu’s question, Song Hailong replied: “I haven’t finished sending the photos yet, this is just the nanny’s room.”

After seeing the subsequent photos sent by Song Hailong, including the entire 200-square-meter house and the rent of 100,000, Zhang Yu silently replied: “Too spacious, I don’t like it.”

On the rooftop after school, Zhang Yu received a rental message from Le Mulan.

He opened the photos of the room and saw, “Hmm… no bed, no sofa, no kitchen, and no TV or anything like that. There’s a medicine cabinet, a quiet room, body training equipment, a washing machine…”

The size was about 60 square meters, plus the standard immortal cultivation decoration, it fully met the needs of Zhang Yu and Bai Zhenzhen.

It’s just that the Ziyun Pharmaceutical “Quick Clean” disinfectant spray at the door made Zhang Yu feel a little uncomfortable.

And the fact that the 60-square-meter house had two toilets also made him feel a little strange.

Le Mulan: “This house is across the street from Ziyun High School. It’s a house I used for a while before. You only need to pay 2,000 per month.”

Le Mulan: “But if you move in, the sparring will be done here in the future.”

Le Mulan: “After all, changing clothes at school is not very convenient.”

Le Mulan: “By the way, this house has two toilets, one of which is for my exclusive use. You can’t enter.”

Zhang Yu calculated that Le Mulan’s exclusive toilet was about 30 square meters, accounting for half the area of this house.

Zhang Yu cursed inwardly, “Damn it… the main body of this house is actually your toilet off-campus, isn’t it? How many exclusive toilets do you need to stake out territory everywhere?”

Zhang Yu: “No problem, I’ll rent this house.”

Looking at the rental information he received today, Zhang Yu felt that he had made a new discovery.

Although Yu Xinghan, Song Hailong, Le Mulan… these rich people probably have very wealthy forces behind them.

But it always felt like… this Le Mulan spends money with less restraint.

Just then, Bai Zhenzhen on the other side of the rooftop said, “Yu Zi, it’s about time, let’s go to Bailong.”

Today was the day to go to Bailong High School for combat training with Yu Xinghan and Song Hailong.

And thinking about fighting with this Golden Core disciple, Zhang Yu couldn’t help but reveal a hint of anticipation in his eyes.
