The Secret of Whale Rubber!

Su Ru looked at Li Fei strangely upon hearing this.

She slowly said, "That is only your speculation. If it truly had such an effect, those who regularly ate Whale Rubber would have discovered it and bought it in large quantities. Its price would surely be extremely high by now, but unfortunately, it is not."

"Because they are consuming it incorrectly."

"Simply eating Whale Rubber can only produce those effects."

"However, if it is melted with high-temperature flames before being absorbed, it can strengthen the body. Of course, this method cannot fully bring out the medicinal power of the Whale Rubber and causes considerable waste."

"The second method is to combine Whale Rubber with certain medicinal herbs and refine them into Pills for consumption. That will allow its effects to be fully unleashed."

Li Fei spoke calmly and unhurriedly.

"Is this recorded in any books?" Su Ru frowned. She had read plenty of books herself, yet she had no recollection of it whatsoever.

As for Pills, she did know that the Breaking Clan was the only sect on the continent that refined them.

However, Plant Academy had no dealings with them.

"No. I figured this out myself, and I have already tested it on myself. It truly works."

"Otherwise, I would not dare spout such nonsense."

Li Fei's words greatly shocked Su Ru.

"You have eaten it!?" Su Ru asked in surprise.

She sized Li Fei up and down with an odd look in her eyes.

"Yes. Last time, I spent Two Hundred Gold Soul Coins at the Plant Auction to buy a piece of Ten Thousand Year Whale Rubber. I combined it with some low-grade medicinal herbs, refined it into Pills, and ate them. The effect was even greater than I expected, and there were no side effects. My Physical Strength should now have reached the level of a Peak Soul Elder or an Initial Soul Ancestor."

"Even absorbing a Five Thousand Year Soul Ring as my Third Soul Ring should not be much of a problem."

Li Fei nodded as he spoke.

"What!?"

Su Ru was stunned upon hearing this.

She immediately grabbed Li Fei's wrist and injected Soul Power into him to examine him.

Li Fei did not resist, because this was the most direct proof of his words.

After examining him, Su Ru sucked in a cold breath.

Delight appeared on her face. "Your body truly is very strong. You are no weaker than an ordinary Early Soul Ancestor, and you can even rival those defense-type Peak Soul Elders!"

"I never expected you to know how to refine Pills as well!"

"Not only did you discover such an enormous secret about Whale Rubber, you can also refine Pills and create your own Soul Skills. You really are a freak!"

Su Ru was overjoyed.

She had truly found herself a treasure.

"Who else have you told about Whale Rubber?" Su Ru asked sternly.

"The Enjing Seven Women, but I did not tell them the truth. I was afraid they might let it slip, so I only said..."

Li Fei repeated what he had previously told the Enjing Seven Women.

"That is good. It is also for their protection."

"Do not tell them under any circumstances. At least until you have grown stronger, the fewer people who know, the better."

Su Ru breathed a sigh of relief and warned him.

"I have always known my limits," Li Fei said.

"Mhm. Teacher believes in you." Su Ru nodded.

Li Fei said, "Next, Teacher should secretly purchase Whale Rubber. Its true use has not yet been discovered, so it is very cheap. Gather as much as possible. Then I can refine it into Pills with medicinal herbs and secretly cultivate Plant Academy's key geniuses, raising the limit of the Soul Rings they can absorb. According to the records, there is a place on the continent called Vast Sea City. It lives by the sea, so there may be more Whale Rubber there. We can take a look."

"Mhm, leave this matter to Teacher. You can focus on cultivating." Su Ru nodded and agreed.

At present, only she and Li Fei knew this secret.

They had to prepare carefully.

Fortunately, she had accepted Li Fei as her Disciple. Otherwise, she would never have learned of such a thing.

Su Ru could not help sighing. "Who would have imagined that something regarded by the world as filthy refuse would turn out to be such a supreme treasure?"

Returning to the Mongolian Yurt on the back mountain,

Li Fei continued cultivating day after day.

Now that he had money and a powerful Teacher, he no longer needed to worry about resources. Someone could also prepare the Whale Rubber for him.

This was a good thing.

He could now focus even more on raising his Soul Power Level.

Time passed in a flash.

In the blink of an eye, a year had gone by.

Over the past year, Li Fei did nothing but cultivate and attend theory classes.

Su Ru had also collected several pieces of Whale Rubber.

However, most of it was only hundred-year or thousand-year Whale Rubber.

He refined them into Pills and tested them.

They did not improve him much.

Moreover, the more he consumed, the less improvement he gained.

He guessed that this might be related to the fact that he had started with Ten Thousand Year Whale Rubber. His body had already adapted to the strength of Ten Thousand Year Whale Rubber, so feeding it Whale Rubber of far lower age did not produce much feedback from his body.

It was as though he had developed drug resistance.

To deal with this situation, he needed Whale Rubber stronger than Ten Thousand Year Whale Rubber.

Still, over the course of the year, his Physical Strength had risen to seven thousand years!

With steady cultivation, his Soul Power had also risen from Level 23 to Level Twenty-Five!

He had advanced by two levels, equivalent to one level every half year!

This efficiency had indeed slowed down.

There was nothing he could do about it. Li Fei's martial soul was ultimately too low in quality.

Even though it had now become the Yin Yang Willow and enjoyed the favor of Yin Yang Two Forces, it was still the same.

What was more, after reaching Soul Grandmaster, the Soul Power Energy required for cultivation increased, making advancement slower.

At this rate, he should be able to reach Level 28 next year.

A ten-year-old Level 28 Soul Grandmaster was already quite impressive on the current continent, belonging among the ranks of monstrous geniuses!

He finally understood why Tang San had advanced so slowly in the Original Book!

Although hundred-year and thousand-year Whale Rubber did not do much to improve his body, they were quite effective for Enjing and the others.

However, he did not tell them that the Pills had been refined from Whale Rubber.

This was also to protect them.

Furthermore, throughout the past year, Su Ru had personally gone out to search rather than entrusting the task to anyone else.

It was all to prevent the secret of Whale Rubber from leaking accidentally.

She moved slowly and handled matters steadily.

According to her, collecting Whale Rubber had not gone well. Even in Vast Sea City, going out to sea was fraught with danger.

Moreover, not every whale-type Soul Beast could produce Whale Rubber.

Only specific kinds, such as Demon Whales and Killer Whales, could produce it.

And those creatures all lived in the Deep Sea Region.

As a result, even Vast Sea City rarely saw Whale Rubber of high age.

Upon hearing this, Li Fei began to think.

Su Ru was acting alone. Without his Heaven-Defying Luck to support her, perhaps she would not find any.

But if he went there personally, would his Heaven-Defying Luck be triggered and help him find some?

"I have cultivated tediously for so long. It is time to go out and explore. Maybe I will truly encounter a fortuitous opportunity that lets me quickly reach Soul Elder."

Inside the Mongolian Yurt, Li Fei silently thought this after finishing his cultivation.

If possible, he would rather absorb a Ten Thousand Year Soul Ring as his Third Soul Ring.

The Soul Power Energy and quality it provided would be enough for the Yin Yang Willow to evolve once more.

That would also bring immense benefits to his future cultivation.

As for the resentment produced by a Ten Thousand Year Soul Ring, it was not a problem for him.

He left the Mongolian Yurt and headed for Su Ru's office.
