Evan almost blurted out "Senior Sister" when he saw Olivia Zhong arrive, but he caught himself just in time.

"Little Sister Zhong, it's you! You scared me," Alex Li said with a cheeky grin.

A quick look at tinyurl.com/2p9emv8w will leave you more fulfilled.

"Who's your little sister?" Olivia glared at him.

"Didn't you say we're from the same hometown? It's only natural I call you that," Alex explained, shrinking his neck.

Olivia retracted her cold gaze and asked indifferently, "What's with the injury on your face?"

Alex's face turned angry. "It's all because of that bastard Evan Chen. Little Sister, you must hate him too. Next time, I'll lure him out, and you can teach him a lesson. How about it?"

Evan wanted to know just how much the Female Demon hated him, so he probed a bit.

"Slap!"

Unexpectedly, Olivia slapped Alex across the face.

"Let me warn you, if you dare harm Evan, I'll destroy you!"

As half of Evan's puppet, protecting her master was an instinct she couldn't resist. Of course, if it were a matter of great importance, she could suppress this impulse with her mental power. But for an ant like Alex, why waste the effort?

"Sorry, sorry, I forgot you two are on the same side," Alex apologized perfunctorily under Evan's control.

Evan secretly rejoiced, thinking that the Female Demon was quite trustworthy. After making a deal, she indeed protected him.

Olivia couldn't be bothered to waste words with Alex and directly asked, "I saw you coming out of the library just now. How did you get in?"

New disciples were not allowed to wander freely, let alone enter such an important place as the library, so Olivia was very curious.

Alex quickly replied, "Little Sister, you forgot. I have connections. If I can't even get such privileges, how can I survive in the future?"

Seeing Alex's smug look, Olivia wanted to slap him again but held back considering the many eyes around them.

Then Olivia said, "Fine. Meet me here at noon tomorrow. I have something for you to do."

Alex looked curious and whispered, "What is it? Are you planning to steal some treasure?"

Olivia frowned and lightly scolded, "The more you know, the quicker you die. Understand?"

Alex rolled his eyes resentfully.

Evan also rolled his eyes secretly, thinking the Female Demon was indeed arrogant, always threatening to kill.

Anyway, he would find out tomorrow. Acting too unusual might reveal his secret of controlling the puppet, so Evan didn't say more.

Just as Olivia was about to leave, Alex called out to her, "By the way, Little Sister, Evan wants you to find him when you have time. He said he has something to discuss."

Olivia ignored Alex and left on her own.

"Acting all aloof," Alex muttered.

Evan thought to himself, "Well, at least she's not aloof towards me," and decided not to complain about her.

Later.

Evan arrived at the trading area.

This trading area was much larger than the market, but to Evan's surprise, there was also a branch of the Immortal Treasure Pavilion here.

"Could it be that the Immortal Treasure Pavilion is really run by Immortal Emperor Weiyang's brother-in-law? No wonder it's so prosperous."

Being able to set up a shop in this spirit cave was impossible without a significant background.

Evan controlled Alex's body, leisurely strolling around.

Two hours later, after some bargaining, Evan sold most of the gifts he received today, keeping only some useful elixirs.

He made over fifty thousand Immortal Crystals!

Back at his old residence, Evan couldn't stop smiling. If he were still toiling in the mining area, how many years would it take to save up this much?

With this huge income, Evan was willing to spend.

He bought some useful Immortal Talismans, herbs, and dozens of ordinary weapons, spending a total of ten thousand Immortal Crystals.

...

While controlling Alex, Olivia's elusive figure had already arrived in the courtyard.

Earlier, Alex told her that Evan had something to discuss, so she thought Evan had come to his senses and wanted to teach her another technique.

So she took some risk and rushed over.

"What do you want?"

When her voice reached the house, Evan realized Olivia had arrived.

"Wow, impressive."

Evan couldn't help but admire her secretly. The Female Demon was indeed stealthy, making her skills enviable.

"Senior Sister, please come in."

Evan opened the door to the small house.

Olivia entered and stood facing Evan.

"Speak quickly, don't waste my time," Olivia said indifferently.

"It's nothing much. I know you're very powerful, Senior Sister. Do you have any methods to improve my aptitude?" Evan asked directly.

"That's it?" Olivia frowned.

"Yes," Evan nodded. "Don't worry, I won't ask for your help for free. I have techniques to trade."

Olivia's frown relaxed, and she asked, "What technique?"

Evan thought for a moment, searched his mind, and found a lower-level technique. "A technique that can transform you into a demon dragon. It's very powerful!"

Olivia asked curiously, "How does it work?"

Evan briefly scanned the main points and said, "You capture a Crimson Demon Snake, use this secret method to merge it with yourself, and then slowly refine and cultivate it. Eventually, you can transform into a demon dragon covered in spikes, very formidable."

Olivia immediately lost interest. She knew this was called the Mutated Demon Technique, extremely difficult to cultivate and full of drawbacks. It wasn't a good technique.

However, such a technique wasn't easy to come by.

How many good techniques does this guy have in his head?

"Not interested. Do you have anything else?"

"Can't think of anything for now."

Evan had plenty of techniques, but he couldn't just give her whatever she wanted. Keeping her interested was the best strategy.

"Hmph."

Olivia could guess what Evan was thinking.

"You already have an immortal body. Purifying your essence and marrow won't significantly improve your aptitude, but if you undergo a complete transformation, there's still hope."

Olivia wasn't in a hurry to get the techniques. As long as this guy was alive, she could obtain them.

"A complete transformation? How does that work, and how much can it improve my aptitude?" Evan was secretly delighted but maintained a calm facade to avoid giving Olivia leverage in negotiations.

Olivia didn't bother beating around the bush. "The Great Transformation Technique, as the name suggests, replaces your original immortal body and bones with something more potent. The process is excruciating, beyond what ordinary people can endure. Are you sure you want to try?"

Evan pondered for a moment. "Show me the cultivation method first. Maybe the pain won't be that bad for me."

Olivia smirked disdainfully. "Ignorant. Many have tried to change their aptitude, but how many have succeeded? The risk is enormous, with a near-certain chance of death. Even if you succeed, the pain could drive you insane, turning you into a walking corpse. Do you still dare to try?"

Evan rolled his eyes, thinking, "Just give it to me already."

Olivia thought to herself that this coward wouldn't dare to cultivate it, so it didn't matter if she gave it to him.

She then condensed the Great Transformation Technique with her mental power and transmitted it to Evan's mind.
