Douluo V: Starting with daily check-ins, I'm trying to trick Xiao Wu into becoming my wife.

Looking at the natal poison pill floating in Dugu Bo's palm, glowing with a green light, Ao Yin sighed inwardly.

This old poisoner was indeed extremely meticulous. Even though they had reached a cooperation agreement and were preparing for him to cure the poison, he still took precautions at every step until the very last moment, never daring to relax his vigilance and leaving behind backup plans to restrain him.

Ao Yin could only wave his hand helplessly, with a look of both laughter and tears on his face: "Senior, you are really overthinking it. I have made it very clear from beginning to end that all the poisons in the world have no effect on me, and it is impossible for me to be harmed by your poison. You don't need to be so cautious."

Dugu Bo's eyes were cold and solemn, showing no sign of relaxation as he stared at Ao Yin and spoke slowly and deliberately.

"You think this is just an ordinary poison pill? You're so wrong!"

"This is my Azure Phosphorous Serpent Emperor Martial Soul, refined bit by bit over decades. It has long since become completely symbiotic with my bloodline, soul power, and divine soul!"

His tone suddenly became more serious, carrying a strong warning connotation.

"In other words, if you dare to take on this treatment today and accidentally kill me along the way, or if you harbor malicious intentions and deliberately delay or evade the process, this symbiotic inner core will immediately unleash a backlash from its very source!"

"Even if you are immune to all poisons, you cannot escape the fate of severe damage to your soul and death on the spot! Therefore, you had better do your best to completely remove the poison from me and Yan'er!"

Ao Yin clicked his tongue inwardly, thinking to himself that Dugu Bo was too ruthless.

To ensure the treatment was foolproof and to prevent any accidents, he actually took out his martial spirit essence core, which he had cultivated for his entire life, to lock the lives of both of them.

But Ao Yin instantly understood the deeper meaning behind it.

This is both a check and balance, and the ultimate expression of trust.

Dugu Bo was proud and aloof throughout his life and never trusted anyone, but now he was willing to risk his life and give me his life core, which is enough to prove that he placed all his hopes on my antidote.

If he could completely cure the stubborn poison in him and Dugu Yan, this invaluable Jade Phosphorous Serpent King's Inner Core would be his greatest reward.

Dugu Bo stared at Ao Yin and solemnly promised again.

"If you are truly dedicated to curing my grandmother and grandson of the poison, and have no selfish motives, then once the poison is eradicated, this inner core will be entirely yours!"

"With it to temper your physical body, purify your soul power, and nourish your martial soul, your cultivation speed will increase several times over, and your mastery of poison will skyrocket!"

Ao Yin shrugged slightly, his expression calm and composed.

He possesses an invincible sign-in system, allowing him to cultivate at a speed unmatched throughout history, without needing to rely on external aids to enhance his cultivation.

But he also understood that this was Dugu Bo's last trump card, and he didn't need to make too many excuses.

With his mind made up, Ao Yin no longer hesitated. He raised his hand to take the cool, moist, and subtly poisonous inner core of the Azure Phosphorous Serpent King, and swallowed it directly.

His movements were swift, decisive, and utterly confident, without the slightest hesitation or fear.

Such a decisive attitude stunned Dugu Bo, who had lived most of his life and was used to the wickedness of people's hearts, and his face was full of surprise.

He had thought Ao Yin would be wary and hesitant, but he never expected the other party to be so open and honest.

After a brief moment of stunned silence, Dugu Bo suppressed his emotions and urged him in a deep voice.

"Our lives are now intertwined; we share both glory and ruin!"

"Begin the treatment immediately! If there is even the slightest deviation during the process, I will personally guide you!"

Ao Yin chuckled inwardly.

To have a titled Douluo waiting for his guidance—looking across the entire continent, probably only he would dare to have such confidence.

Dugu Bo felt slightly frustrated, but there was nothing he could do, because Ao Yin's understanding of poison was indeed far beyond his own.

After a long pause, he managed to squeeze out a stiff "Okay!"

The more confident and composed the other person was, the more at ease and secure he felt.

After all, with the inner core and symbiosis, Ao Yin dared not make the slightest mistake.

Without wasting any more time, Dugu Bo immediately sat cross-legged on the bluestone, his body surging with emerald green soul power.

The immense power belonging to a Title Douluo swept across the entire arena. He mobilized the qi and blood in his entire body's meridians, forcibly peeling away and gathering the deadly poison of the Jade Phosphorous Serpent King that was rooted in his blood and penetrated his bone marrow.

He wanted to force all the deadly poison that had plagued him for half his life into his own soul bones and seal it away forever.

This is an extremely demanding and time-consuming process that cannot be rushed.

Ao Yin stood quietly to the side, protecting the Dharma, his expression calm.

He knew in his heart that this treatment to seal the poison would take a very long time, and he would have to stay in the Ice and Fire Yin-Yang Eye Secret Realm for a long time afterward.

Day and night alternate, day and night cycle.

As the pitch-black night slowly faded, the dawn's light bathed the entire secret realm.

Just as a new day was dawning, a crisp system notification rang out in Ao Yin's mind right on time.

[Ding! Daily check-in count has been refreshed!]

Ao Yin's eyes lit up, and he instantly made up his mind.

The Yin-Yang Eye of Ice and Fire is a top-tier treasure land nurtured by heaven and earth, with boundless fortune and abundant spiritual energy, far surpassing all other cultivation holy lands outside.

By consistently checking in here, you're guaranteed to encounter countless incredible opportunities!

"System, sign in immediately!"

[Ding! Congratulations on successful check-in! You have received a Level 4 reward: Your Soul Ring's age has increased by 100,000 years!]

"hiss!"

Ao Yin gasped, his heart filled with elation.

Directly increases the age of the Soul Ring by 100,000 years!

He is now a level 50 Soul King, and all his Soul Rings have reached the quality of 100,000 years, instantly closing the gap to the legendary million-year Soul Rings that are extremely rare in the world!

From this moment on, his cultivation goal was completely aligned with the ultimate peak of the continent!

For the next six months, Ao Yin stayed in the Ice and Fire Secret Realm, checking in on time every day without fail.

A massive amount of top-tier rewards are being continuously refreshed and released.

[Ding! Sign-in successful! Soul Ring age increased by 90,000 years!]

[Ding! Sign-in successful! Soul Ring age increased by 80,000 years!]

[Ding! Sign-in successful! Soul Ring age increased by 70,000 years!]

With each passing day, his soul ring foundation continued to surge, and his base was honed to be incredibly thick and solid.

Unknown to anyone, in this secluded realm of ice and fire, Ao Yin's strength underwent a terrifying transformation in just six months, a transformation that others could not achieve in a lifetime.

...

Six months have passed in the blink of an eye.

With the unique blessing of the Heaven and Earth's Qi at the Yin-Yang Well, coupled with the daily system sign-in rewards that Ao Yin received, his overall strength underwent a complete and radical transformation.

Countless annual increases have accumulated and stacked, finally breaking the limit today!

At this moment, Ao Yin's soul ring foundation was completely sublimated. Among them, the first soul ring of the Dark Sacred Dragon, the Dark Gold Terror Claw Bear, broke through the 100,000-year shackle and stacked up to the million-year limit!

Standing in the spiritually rich Ice and Fire Secret Realm, Ao Yin's expression was calm, but his eyes held a turbulent undercurrent.

He glanced sideways at Dugu Bo, who was still sitting cross-legged beside him, focused on expelling the deadly poison from his body, and his eyes instantly lit up with an astonishing light.

It has to be said that Poison Douluo is definitely my greatest lucky star!

If it weren't for the chance encounter with the Ice and Fire Yin-Yang Well, and if Dugu Bo hadn't tacitly allowed him to occupy the entire Immortal Medicine Garden and permitted him to cultivate and sign in there for an extended period, he would never have been able to achieve such a terrifying leap in strength in just half a year.

Now, his overall combat power has increased by several levels, and his foundation is so profound that even he himself is shocked!
