Meridian Cleansing Pill, Yin Yang Spirit Infusion Pill, the Terror of Pills!

Over the past two days, Dugu Yao and Dugu Yan had thrown themselves wholeheartedly into cultivation. Although their Soul Power Levels could no longer be raised for the time being,

the Soul Power they cultivated would not disappear. Instead, it would accumulate within their bodies, waiting until they absorbed Soul Rings and broke through their bottlenecks before being released as Soul Power Levels.

As for Dugu Xin and Lin Wanqiu, they cultivated whenever they had time, and during their free time, they would tend to the herbal shop. That was their main source of income.

Above Sunset Forest, dark clouds blanketed the sky as lightning flashed and thunder roared. Bolts of lightning as thick as water buckets struck down from time to time, and this scene had continued for two full days.

The surrounding area had been scorched black by lightning. The Spirit Beasts had long since become like frightened birds, avoiding the area struck by the lightning, their bodies trembling as they watched from afar.

"Goddamn it, Heaven! Fuck your ancestors!"

Rumble! A seven-colored bolt of lightning struck downward.

Dugu Bo's clothes had long since been ruined. His face was charred black, his body scorched outside and tender within, black smoke drifting from his mouth as he watched the dark clouds gradually disperse.

These thunderclouds had been caused by him. What had caused them?

Naturally, it was pill refinement. As long as a pill reached the seventh grade, Pill Thunder would form upon its completion. This was a restriction imposed by the rules of heaven and earth.

For pills of the seventh grade and above, including seventh-grade Pills, the rules of heaven and earth would create Pill Thunder to test the pill upon its completion. If it endured, the pill would be successfully formed.

If it failed to endure, the pill would be destroyed!

Of course, the pill refiner could bear the Pill Thunder in the pill's place. But how powerful was Pill Thunder? Even Dugu Bo was having trouble enduring two days of lightning strikes.

The power of seventh-grade Pill Thunder was roughly equivalent to the strongest strike of a Soul Sage, while the Pill Thunder of eighth-grade Pills was equivalent to the strongest strike of a Soul Fighting Douluo. In just these two days,

he could be said to have suffered the strongest attacks of more than a dozen Soul Sages and seven or eight Soul Fighting Douluos. Moreover, Pill Thunder was intangible, so he could not fight back.

He could only rely on defensive Soul Skills and the strength of his body to withstand it head-on. Although it had dealt him considerable damage, after using the Pill Thunder to temper his body, his physical capabilities had clearly become even stronger.

He took out a fresh set of clothes from his Soul Tool and changed into them. Looking at the finished pill inside the Pill Furnace, he grinned with delight, took it out, and placed it inside an exquisite wooden box.

Inside the wooden box were already more than twenty pills the size of fingernails. These pills were the result of his tireless efforts over the past two days and nights!

After consuming a vast amount of spiritual herbs and medicinal plants, he had only produced a little over twenty pills.

Fortunately, the Ice and Fire Yin Yang Eye lacked nothing when it came to spiritual herbs and medicinal plants. Otherwise, given his rate of failure, let alone more than twenty pills, he probably would not have managed to refine even ten!

The main pills he had refined were the seventh-grade Supreme Soul Protecting Pill, which could directly grant immunity to soul attacks, and the seventh-grade Saint Breaking Pill, which could raise a Soul Sage's Soul Power by one level.

There was also the seventh-grade Meridian Cleansing Pill, which cleansed the marrow, healed hidden injuries within the body, and enhanced physical and spiritual strength.

The remaining one was an eighth-grade pill, the Yin Yang Spirit Infusion Pill!

This was the pill whose effects he considered the most terrifying. It could actually raise the level of Innate Soul Power. Innate Soul Power was something predetermined from the moment one awakened their Martial Soul!

This pill could raise Innate Soul Power by a full five levels!

In other words, someone with level-one Innate Soul Power could take a Yin Yang Spirit Infusion Pill and become a little genius with level-six Innate Soul Power.

If a Soul Master with level-five Innate Soul Power took it, their Innate Soul Power could reach the astonishing level of full Soul Power!

Of course, this pill could only raise Innate Soul Power to full Soul Power at most. Even if someone with level-eight Innate Soul Power took it, they could only gain two additional levels in the end.

Then there was the eighth-grade Poria Azure Spirit Pill. After a Soul Fighting Douluo took it, all attributes would increase by 100%. For a Titled Douluo, the effect would be halved, but even halved, it was still a Trump Card for a Titled Douluo!

The final pill he had refined—the one he had just finished refining—was the Bone Regenerating Blood Dissolving Pill. It could instantly restore all injuries. As long as one still had a breath left, it could keep them from dying!

It was extremely difficult to refine. If the difficulty of refining seventh-grade Pills could be called hard, then eighth-grade Pills were hell, and ninth-grade Pills were purgatory!

With seventh-grade and eighth-grade Pills, he could still afford to make mistakes because of the abundance of ingredients. But ninth-grade Pills were different. The ingredients required for ninth-grade Pills were all exceedingly rare.

Even at the Ice and Fire Yin Yang Eye, such ingredients were not commonly found. Therefore, before his pill-refining techniques matured, he would not attempt to refine ninth-grade Pills!

Dugu Bo put away the wooden box and looked around. The area was already unrecognizable. The ground was scorched black, and the surroundings looked as though they had been ravaged by a fierce wildfire.

This was all caused by the Pill Thunder. As for the Spirit Beasts that had originally lived nearby and had failed to flee before the Pill Thunder descended, they had long since been scorched outside and tender within, giving off an enticing aroma.

"After two days, Yao'er and the others must be getting impatient."

"This Meridian Cleansing Pill can enhance the body and spiritual power. Even for me, its effects are obvious."

"If Yao'er and Yanyan take it, Yanyan's Second Soul Ring will probably be able to reach nearly ten thousand years. As for Yao'er, a Ten-Thousand-Year Soul Ring is already a certainty."

With that, Dugu Bo leaped away, taking the pills refined over the past two days and returning to Dugu Manor.

At this moment, inside a room in Dugu Manor, Dugu Yan leaned against the windowsill and gazed outside. "Brother, why hasn't Grandpa returned yet? Father said that dark clouds have been rolling over Sunset Forest these past two days, and lightning has been striking down as well."

"Could Grandpa have caused it?" Dugu Yan was exceptionally clever. Thinking that the dark clouds had appeared only during the two days since her grandfather left, she connected it to pill refinement.

As he refined his Soul Power, Dugu Yao said, "That's right. Grandpa should be refining seventh-grade Pills or even higher-grade pills."

"If these pills are successfully refined, they will draw down heavenly lightning. It is a test for the pills. If the pill endures it, it will be completed. If it cannot, it will be destroyed!"

"However, this Pill Thunder can be interfered with by people. A Soul Master can bear it personally. Still, this amount of Pill Thunder should not have much effect on Grandpa."

"Grandpa should be back soon." Dugu Yao spoke calmly.

He knew the power of seventh-grade Pill Thunder. The Nine Nether Pill Codex recorded that it was roughly equivalent to the strongest strike of a Soul Sage. He also knew about the Pill Thunder of eighth-grade Pills.

It was roughly equivalent to the strongest strike of a Soul Fighting Douluo. This referred to the strongest attacks of a level-79 Soul Sage and a level-89 Soul Fighting Douluo.

Although its power was immense, there would be no problem for his grandfather to withstand it. But ninth-grade Pill Thunder was somewhat dangerous—it could kill people.

The power of ninth-grade Pill Thunder was roughly equivalent to the full-force strike of a level-99 limit Douluo!
