So what if I'm useless? I'll become a saint!

Ling Jiuan stared at Lei Tingyi with a complicated look on his face.

She thought of the biological father of this body, the man who should have given her shelter but never really cared about her, and even in a dangerous place like the secret realm, he never considered whether she would encounter any accidents.

In contrast, Lei Tingyi, who was just a chance acquaintance, was willing to protect her time and time again, making her feel unprecedented warmth in times of crisis.

This feeling of being cared for and protected seemed something she had never experienced before, even in her life in the 21st century.

This made her feel deeply moved, and an inexplicable emotion welled up in her heart.

She sighed softly, trying to suppress the strange emotions in her heart.

At this time, Lei Tingyi also felt the changes in the surrounding spiritual energy.

The spiritual energy around this cold pond seemed to be several times purer than that outside, which made his spiritual power flow more smoothly.

In just a moment, Lei Tingyi felt that the constraints on his golden elixir seemed to have loosened a little.

He had an idea in his mind and immediately used his spiritual power to try to channel this pure spiritual energy into his dantian in order to completely break the shackles.

However, just as he was sprinting with all his strength, a backlash force suddenly hit him.

Lei Tingyi only felt a tightness in his chest and a sweetness in his throat, and a mouthful of black blood spurted out.

Seeing this, Ling Jiuan's face suddenly changed and he hurried forward to support him.

"Thunder Yi!"

There was worry in her voice.

Lei Tingyi waved his hand, indicating that she need not panic.

He wiped the blood from the corner of his mouth and spoke lightly.

"It's okay, it's just that my spiritual power hasn't fully recovered yet."

Although his tone was relaxed, Ling Jiuan could still feel his weakness at the moment.

An inexplicable emotion surged in her heart, a mixture of gratitude and worry.

In this strange world, she seemed to have met someone she could rely on, and this person stood up for her time and time again.

But Lei Tingyi seems to have his own powerful opponents to face.

And there was absolutely no way she could beat his opponent.

For a moment, Jiuan felt complicated.

Lei Tingyi took out a pill from the space, swallowed it without hesitation, then sat cross-legged on the ground and began to regulate his breathing quietly.

His face gradually turned from pale to rosy, and after about a quarter of an hour, he returned to normal.

He slowly opened his eyes and looked at Ling Jiuan with a deep gaze, his tone calm.

"The spiritual energy here is extremely pure. You can use the essence and blood of the water monster to strengthen your body and assist in your cultivation. This way, you will be able to achieve twice the result with half the effort."

When Ling Jiuan heard this, a hint of hesitation flashed in his eyes.

She thought of her previous experience and couldn't help feeling a little worried.

"But I just attracted the water monster because of my breakthrough in cultivation."

Lei Tingyi's expression remained indifferent, as if everything was under control.

"Just practice, I'll keep watch over you."

Although his voice was not loud, it revealed a strong sense of confidence and security.

Ling Jiuan looked at him, and the hesitation in his heart gradually dissipated.

"it is good."

She nodded and decided to trust Lei Tingyi.

Afterwards, Ling Jiuan took out the water monster's blood essence and pretended to drink it.

However, at this moment, Lei Tingyi's face changed and he quickly reached out and grabbed her wrist.

"What are you doing? Do you really want to die?"

There was a hint of annoyance and confusion in his tone.

Ling Jiuan was startled by his reaction and smiled awkwardly.

"I thought that if I took the essence and blood directly, the effect might be better. Maybe I could break through several levels at once."

Lei Tingyi's expression did not improve, but became even uglier.

She knew that she was indeed a bit reckless this time. If Lei Tingyi hadn't stopped her in time, the consequences would have been disastrous.

So she carefully collected the essence and blood of the water monster and planned to practice according to Lei Tingyi's advice.

Seeing Ling Jiuan obediently smearing the water beast's blood essence evenly on his body, Lei Tingyi's tense expression finally relaxed a little.

He was well aware of Ling Jiuan's anxiety, however, as an experienced practitioner, he understood even more clearly the tyranny and power contained in the essence and blood of the Jindan stage monster.

If Jiuan really drank it, he would probably explode and die instantly, with both his body and soul destroyed.

As time went by, Ling Jiuan began to realize the power of the water monster's blood essence.

She had just closed her eyes and started regulating her breathing when she felt a burning pain on her skin.

The pain was like a burning flame. In just a moment, she was sweating profusely and her face turned extremely pale.

Ling Jiuan gritted his teeth and tried hard to endure the unspeakable pain.

As spiritual power continued to flow into her dantian, she felt as if her body was being pulled left and right by an invisible force, and every inch of her skin and every bone seemed to be torn apart.

This kind of pain was almost unbearable for her, but Jiuan knew that it was a necessary step in her cultivation.

She tried hard to keep her mind clear, constantly adjusting the rhythm of her breathing and spiritual power, trying to find a balance in this overbearing power of essence and blood.

Lei Tingyi fixed his eyes on Ling Jiuan, and seeing the pain and struggle in her expression, he couldn't help but feel worried.

He frowned subconsciously, and wanted to release the spiritual power condensed in his hands several times, but he was struggling with whether he should lend a hand.

He knew very well that this was a critical moment in Ling Jiuan's practice, and any help from the outside might disrupt her rhythm and even ruin all her previous efforts.

The next moment, Ling Jiuan suddenly cried out in pain.

"what!"

Her voice was filled with pain and helplessness.

However, she quickly suppressed the cry. She gritted her teeth and used her strong will to withstand the unbearable torment.

Seeing this, Lei Tingyi felt both admiration and heartache.

He could see that the spiritual energy around Ling Jiuan's body began to become violent, as if it was rampaging through her body, looking for a breakthrough.

This kind of pain was difficult to endure even for a master like him, but Ling Jiuan persevered with his amazing perseverance.

Suddenly, Ling Jiuan spat out a mouthful of blood and his face instantly turned pale as paper.

Lei Tingyi subconsciously wanted to protect her, but she raised her hand to stop him.

"No, I'll do it myself."
