Strengthen your offspring. All my descendants are big shots in the fairy world.

Familiar scene, familiar actions, but today's feeling was somewhat different.

Qin Changqing clearly felt a stream of clear energy涌入 from the other party's body into his own, actually causing a significant improvement in his cultivation.

Qin Changqing's heart stirred, understanding dawned.

This should be the Six Desires Demon Sect's unique dual cultivation method, capable of 'harvesting yin to supplement yang,' or 'harvesting yang to supplement yin,' a special method for mutual improvement through dual cultivation.

However, from the looks of it now, he suffered no loss, but instead gained quite a few benefits; it seemed the Six Desires Demon Sect was trying to show goodwill.

Tang Zhifu was a Golden Core stage cultivator, so the spiritual energy she provided as feedback naturally had a considerable effect on Qin Changqing, who was still in the Foundation Establishment stage.

Qin Changqing was overjoyed. The Six Desires Demon Sect was indeed sensible. If this continued, his cultivation would progress even faster!

He had gained another path to becoming stronger without having to cultivate.

Winning while lying down, I'm serious!

The familiar multiple-choice question popped up, pulling Qin Changqing back from his surprise.

[Detected that your partner has Supreme-grade Spiritual Roots, please choose:]

[1. Consume 10 years of lifespan to strengthen the seed, can produce offspring with High-grade Spiritual Roots]

[2. Consume 100 years of lifespan to strengthen the seed, can produce offspring with Supreme-grade Spiritual Roots]

[3. Consume 1000 years of lifespan to strengthen the seed, can produce offspring with Earth-grade Spiritual Roots]

[4. Consume 10000 years of lifespan, can produce offspring with Heaven-grade Spiritual Roots]

[5. Consume 100000 years of lifespan, can produce offspring with Heaven-grade Spiritual Roots]

Only Supreme-grade Spiritual Roots?

Qin Changqing was somewhat surprised, and his impression of the Six Desires Demon Sect improved even more.

The Six Desires Demon Sect didn't arrange for a female cultivator with the highest aptitude right away, like other sects would. Tang Zhifu only had Supreme-grade Spiritual Roots, but she was extremely beautiful and very good at taking care of people, clearly conveying a signal of goodwill to him.

This made Qin Changqing very comfortable, without giving him the feeling of being manipulated and used as a tool, as he had felt before.

Finally, he was being treated like an emperor!

The morning sun rose!

Qin Changqing, looking refreshed, watched Tang Zhifu leave.

Now he was in control of the situation, and he no longer had any aversion to having children. The more children, the greater the benefits to him.

Moreover, he now had a good impression of the Six Desires Demon Sect. The Six Desires Demon Sect's dual cultivation method also improved his cultivation, so why not?

The former was overjoyed, bowed, and turned to leave.

Wu Mingzhen laughed heartily upon hearing the news, feeling somewhat smug.

It seemed that his actions were correct, and he had indeed won Qin Changqing's favor. He waved his hand and said, "Quickly arrange it! Don't neglect Fellow Daoist Changqing!"

"Yes!"

The Six Desires Demon Sect specialized in dual cultivation, and the female cultivators also knew how to please men. Qin Changqing had fallen into a gentle embrace and was living very comfortably.

Happy times are always short!

A year was about to pass, and his cultivation had also improved to the peak of the Foundation Establishment stage. The Azure Cloud Mansion of the Six Desires Demon Sect was also filled with female companions.

Qin Changqing hadn't been idle this year. There were now more than three hundred female companions in the Azure Cloud Mansion, and all of them were pregnant.

The more children, the more cultivation was fed back.

Qin Changqing was very satisfied.

Wu Mingzhen couldn't stop smiling about this, and often came to chat with Qin Changqing to show goodwill, asking him what he needed, and the Six Desires Demon Sect would try its best to satisfy him.

Of course, he would also occasionally inquire about the Black-Robed Alliance Master's news from the side.

Qin Changqing was vague about this, saying he didn't know anything, and Wu Mingzhen was helpless.

...

After sending away another stunningly beautiful female cultivator, Qin Changqing stretched. It had been a bit too frequent lately, and he needed to rest.

Suddenly, Qin Changqing was slightly stunned, and a system notification sounded in his mind.

[Congratulations to the host, successfully consumed 100 million years of lifespan, system upgrade...]

Had he already consumed 100 million years?

Qin Changqing was taken aback, but then he understood. These years, he had not only consumed lifespan to strengthen his children, but also consumed a lot through constant teleportation. It was indeed about right.

Soon, the system upgrade was successful, and the interface reappeared.

[System upgrade successful, the following new functions have been added:]

[1. Enabled exploration function, consume lifespan to explore the surrounding world, the more consumed, the farther the exploration...]

[2. Enabled re-strengthening function, consume ten times the initial lifespan to further enhance the talents of offspring after birth...]

[3. Enabled bloodline strengthening function, consume lifespan to enhance the bloodline power of offspring...]

[4. Enabled soul strengthening function, consume lifespan to enhance the spirit and soul power of offspring...]

[5. Cultivation feedback upgrade, on the original basis, the feedback is increased tenfold, the maximum feedback does not exceed the cultivator's cultivation base...]

[6. Hidden function re-upgrade, can consume lifespan to help children hide their strength and talents...]

Qin Changqing's heart pounded, overjoyed.

What he wanted came true. As soon as he wanted to find a suitable treasure land, the system immediately arranged an exploration function for him.

As expected of his own system! Awesome!

Qin Changqing began to carefully study the system.

First of all, there was the exploration function. As long as he had enough lifespan, he could even explore other worlds.

However, the consumption of lifespan was too terrifying, often tens of thousands of years at a time. Qin Changqing couldn't afford it now and didn't dare to try it easily.

As for the re-strengthening function, it allowed him to re-strengthen the talents of children who had already been born, but it required consuming ten times the lifespan of a normal strengthening.

For example, if Qin Qiming only had High-grade Spiritual Roots, strengthening him to Supreme-grade would require ten times the initial lifespan for strengthening Supreme-grade Spiritual Roots, which was ten times 100 years, meaning it would require a thousand years of lifespan to strengthen him from High-grade to Supreme-grade.

If he calculated it this way...

Qin Changqing swallowed. Wouldn't this cost him his old life? It seemed that he had to accumulate more spirit stones to increase his lifespan in the future, otherwise, he wouldn't be able to withstand it with so many children.

Strengthening bloodlines and souls was similar to the previous spiritual roots and physiques, but it required the cooperation of women with bloodline power and special soul talent to conceive and strengthen.

The improvement of the feedback function was what Qin Changqing valued most, as it was directly related to his cultivation!

This function had increased tenfold on the original basis, and the maximum feedback could only be the full amount!

In other words, children with High-grade Spiritual Roots would originally return one-tenth, but now they could return the full amount!

Children with Supreme-grade Spiritual Roots increased from the original one percent to one-tenth, and Earth-grade Spiritual Roots increased to one percent...

Awesome!

Qin Changqing's eyes lit up, and he couldn't help but look forward to it even more.

Having a second upgrade meant there might be a third.

Then, if the system upgraded again and again... and again, wouldn't he be able to return all the cultivation of all his children to him when it reached a certain level?

Wouldn't his cultivation then be equal to the sum of all his children's cultivation!

Just thinking about it was terrifying and exciting!

His children's talents were all more powerful than the last, and they were all very terrifying. Plus, he could now help them re-strengthen their talents. As long as they didn't die, becoming immortals and ancestors in the future wouldn't be a problem. By then, how much would his strength have grown?

The more Qin Changqing thought about it, the more excited he became, and he had already begun to daydream.

By then, he wouldn't have to wear the skin of the Black-Robed Man and act like a tiger. He could crush them with his true strength. Who would dare to disobey?

However, that was in the future. After thinking about it, he still had to calm down and take it one step at a time.

The re-upgrade of the hidden function was very important for the present.

He could consume lifespan to hide his children's strength and talents.

This was equivalent to equipping his children with ghillie suits, playing the pig to eat the tiger. Everyone could become a 'Old Six'!

This increased their safety.

Often, the 'Old Six' are the ones who survive to the end!

Moreover, coupled with the re-strengthening function, it was even more awesome!

He could completely help the children with High-grade Spiritual Roots improve and then secretly hide their talents, so that it wouldn't attract attention and allow the children to maintain their current state of mind and continue to cultivate diligently.

The children with High-grade Spiritual Roots were almost all Qin Changqing's early children, born to him and his mortal wives.

They were also the children that Qin Changqing spent the most time with and had the best feelings for.

Now that he could help them re-strengthen their talents, Qin Changqing was naturally very happy.

Qin Changqing immediately improved the talents of his two hundred and seventy-two children with High-grade Spiritual Roots, raising them to Supreme-grade Spiritual Roots.

Each child required a thousand years of lifespan, which added up to two hundred and seventy thousand years.

Then, he helped them hide their talents and strength. The consumption varied depending on their strength, but most of them were in the Foundation Establishment stage, so it only required about a hundred years per child.

This wave of improvement and hiding consumed more than three hundred thousand years.

Qin Changqing stopped and didn't continue. He would continue to help them reach Earth-grade Spiritual Roots after a while.

Raising them too much at once would definitely be very obvious in terms of cultivation speed, and he was worried that the children would become proud!

If it affected their Dao hearts, it would be a good intention that turned into a bad thing...

Then, Qin Changqing also raised the children with Supreme-grade and Earth-grade Spiritual Roots by one level.

As for those above Heaven-grade Spiritual Roots, he didn't plan to touch them for the time being.

The main reason was that it consumed too much lifespan, and his remaining lifespan couldn't withstand it now. Moreover, Heaven-grade Spiritual Roots were already good enough, and they were completely sufficient for early cultivation. It wouldn't be too late to improve them later, and Qin Changqing would be able to save more lifespan by then.

Having too good of a talent in the early stage wasn't necessarily a good thing.

Qin Changqing was also considering everything comprehensively!

It could be said that for the sake of his children, this old father had really broken his heart!
