Because of the difference in time flow between the Realm of Living Beings and the Netherworld, Lin Yun brought the people from the Netherworld back to the Blood Fiend Universe in just a dozen breaths in the Realm of Living Beings. He also gave the ghost cultivators of the Netherworld some pointers on their cultivation.

"I'm back!"

"I'm finally back!"

Everyone was very excited that Lin Yun had brought them back to the Blood Fiend Universe.

No matter how good the Netherworld is, the Blood Fiend Universe is their true home.

Especially Xia Qingqing, Lin Mengmeng, and their group, who were the closest to Lin Yun, were affected by the fact that time flowed too fast in the Netherworld. Lin Yun was in the Realm of Living Beings, while they were in the Netherworld. They would not see Lin Yun for tens or hundreds of thousands of years at a time, which was far too long for their original lifespan of only a few decades.

In comparison, they preferred to wait for Lin Yun in places with lower time flow. If it weren't for their efforts to cultivate and catch up with Lin Yun's cultivation level as quickly as possible, they probably wouldn't have stayed in the Netherworld High Heaven for so long.

Now that Lin Yun has brought them back to the Blood Fiend Universe, they are naturally even happier.

They even thought that if there were no external enemies, they could stay in the Blood Fiend Universe indefinitely, so that even if Lin Yun returned to the Netherworld to cultivate, they would only need to wait a very short time.

"Alright, the power of heaven and earth in the Blood Fiend Universe can probably only last for a few months. You should take advantage of this time to cultivate!" Lin Yun said at this moment.

"Um!"

"good!"

Everyone nodded in agreement.

On their way back, Lin Yun had already explained the details to them. They knew this was a rare opportunity and didn't waste any time.

Next, everyone immersed themselves in cultivation.

One month... two months... three months...

During this period, after Lin Yun's clone completely solidified the Nine-Patterned Divine Core in the Netherworld, he cultivated in the High Heaven of the Netherworld for a period of time before returning to the Blood Fiend Universe to cultivate.

Lin Yun's main body stabilized its cultivation at the intermediate level of the Divine Realm, while Lin Yun's clone stabilized its cultivation at the lower level of the Divine Realm. Both the main body and the clone were rapidly progressing together.

Three months later, Lin Yun's magic weapon, the Heavenly Dao Tower, broke through to the mid-grade Divine Realm level.

As Lin Yun had predicted, the Heavenly Dao Tower, having broken through to the mid-grade Divine Realm level, could store even more energy for upgrading the Blood Fiend Universe.

At this time, the Blood Fiend Universe had not yet finished its upgrade, so the Heavenly Dao Tower's upgrade at this moment was very timely.

Although the Heavenly Dao Tower itself absorbs and refines this energy at a much slower speed than Lin Yun and the Blood Prison Sword, as it upgrades, the amount of energy it absorbs and refines from the Blood Fiend Universe upgrade is no less than what Lin Yun and the Blood Prison Sword absorb and refine.

These precious energies are stored inside the Heavenly Dao Tower. Whether they are slowly digested by themselves or used by Lin Yun and others, they are a considerable resource.

During this period, some ordinary beings from the Holy Domain, or even beings at the Holy King level, who were living or passing by the area, sensed the movement in the Blood Fiend Universe and came to check on its situation. Of course, they were either driven away by Lin Yun's subordinates or entered the Blood Fiend Universe and no longer sent out any information.

Finally, in the fifth month, a lower-level god-realm acquired god was alarmed and rushed to the Blood Fiend Universe again to check the situation.

As a result, Lin Yun made a move and defeated his opponent in one strike, gaining another low-grade divine spark.

In the sixth month, another cultivator from the Lower God Realm arrived, seemingly related to the previous Lower God Realm cultivator, and was also killed by Lin Yun.

"At this rate, the changes in the Blood Fiend Universe probably won't be kept secret for long..." Lin Yun frowned slightly and thought to himself.

In fact, he had considered having the Heavenly Dao Tower subdue the other party, but having the Heavenly Dao Tower subdue the other party was not without risks. He only recently realized that perhaps because of the reason why the Divine Realm cultivators condense their divine sparks, the divine sparks are a very special existence in the world and are very difficult to destroy. Therefore, after the Heavenly Dao Tower subdues the cultivators of the Divine Realm, it cannot immediately change their thoughts.

For a lower-level divine realm, the Heavenly Dao Tower must influence the opponent for at least ten thousand years to completely enslave them. For a middle-level divine realm, the Heavenly Dao Tower must influence the opponent for at least one hundred thousand years to completely enslave them. As for a higher-level divine realm, the Heavenly Dao Tower is currently only at the level of a mid-grade divine artifact and cannot enslave them yet.

When the first cultivator at the lower-level Divine Realm entered the Blood Fiend Universe, Lin Yun was at a crucial point in his cultivation and was too lazy to deal with him. He no longer took a lower-level Divine Realm cultivator seriously and killed him. When the second cultivator at the lower-level Divine Realm entered, Lin Yun discovered that the other party was related to the previous Divine Realm cultivator. Not wanting to waste any effort, he also killed him directly.

Now that his cultivation has come to an end, he has to think about things more.

Are there any intermediate-level Divine Realm cultivators behind these two lower-level Divine Realm cultivators? If they discover the abnormality of these two lower-level Divine Realm cultivators, will they come to help?

What should he do then?

If he were to deal with a mid-level Divine Realm cultivator, what would happen if that person had friends of the same level, or if they had high-level Divine Realm cultivators behind them? And if they came again, how would he handle it?

Most importantly, how often will they come?

"Fine, when another cultivator at the intermediate level of the Divine Realm enters, we'll have the Heavenly Dao Tower enslave them to prevent the news from leaking out. If it does leak out, we'll just have to deal with it as it comes..." Lin Yun paused, sighed inwardly, and thought to himself.

If it's just a cultivator at the intermediate level of the Divine Realm, it's easy to deal with. Although the Heavenly Dao Tower needs 100,000 years of influence to completely enslave the other party, he can take the Heavenly Dao Tower and the other party into the Netherworld.

The time flow difference between the 55th and 63rd heavens of the Netherworld and the Realm of Living Beings is ten million times, or one hundred thousand years. He only needs to place the Heavenly Dao Tower in the Netherworld for three or four days to cover the Great World of Living Beings.

It's just a bit more troublesome.

What Lin Yun was truly worried about were those in the upper-level divine realms.

The fact that the Heavenly Dao Tower, a mid-grade divine artifact, cannot enslave its opponent is one aspect.

Such a powerful figure is an indispensable figure even among countless gods.

If he manages to make it disappear, it might cause quite a stir, and it's not impossible that it would quickly attract the attention of cultivators at the peak of the Divine Realm.

In that case, the Blood Fiend Universe would be completely exposed.

Besides this matter, there was also Shi Zhong, whom Lin Yun had let go. Lin Yun was unaware of the problem with the Heavenly Dao Tower, so he let him leave without worry.

Now, the other party has been away from the Great World of Living Beings for quite some time. If the secret were to be leaked, they would have had the opportunity long ago. The other party knows that he has condensed a nine-patterned divine core.

Once the news spreads, even cultivators at the peak of the Divine Realm will be shaken, and they will likely arrive in the Blood Fiend Universe in an instant.

However, since the other party was a primordial god race that had not given up resisting, and was led by the Azure Lotus God, and his father had once told him that the Azure Lotus God was trustworthy, he was not particularly worried.

Even if the news did leak out, just consider it as him meeting the Azure Lotus God Lord ahead of time.

He has the Netherworld as an escape route on one hand, and the Blood Fiend Universe as a trump card that allows him to be resurrected continuously on the other. He really doesn't need to be afraid of his opponent.

However, traveling in the world of living beings will no longer be as convenient.

Moreover, since the news hasn't leaked for so long, Shi Zhong might not actually reveal it, and even if he does, it might not be recently.

In time, his strength will grow even greater, and then, without Shi Zhong saying a word, he will come knocking on his door.

But ultimately, this is an uncontrollable factor.

As for the illusion he created some time ago, where he was killed by a mid-level Divine Realm cultivator, he never thought it could fool Shi Zhong.

That lower-level Divine Realm cultivator, Gray Leaf, might have been fooled since we hadn't seen his true strength, but Shi Zhong had witnessed his true power; no one is a fool.

Even before he broke through to the Divine Realm, in the Blood Fiend Universe, he could fight against cultivators at the intermediate Divine Realm level, and even joined forces with that Stone Man to kill two cultivators at the intermediate Divine Realm level.

He broke through to the Divine Realm and even condensed a heaven-defying nine-patterned divine spark. To say that he was killed by an ordinary mid-level Divine Realm cultivator would be to fool a fool.

It's just a way to fool some unsuspecting gods.

...

In the blink of an eye, eleven months have passed since the Blood Fiend Universe was upgraded. The nine new layers of the Blood Fiend Universe have been completely condensed, and the upgrade energy within the Blood Fiend Universe has naturally receded.

Another month passed, and Xia Qingqing, Lin Mengmeng and the others also woke up from their cultivation. Lin Yun was right. They had absorbed and refined a large amount of Yin attribute energy in the Netherworld, and during this period they had absorbed and refined a large amount of high-level Yang attribute energy, and each of them had made great progress.

In addition, Lin Yun used some of the upgrade energy absorbed and refined by the Blood Prison Sword to help them. Xia Qingqing, Lin Mengmeng, and Zi Yun have all reached the peak Saint King realm.

In terms of realm alone, they are only one step away from breaking through to the realm of gods.

However, breaking through to the Divine Realm is not so easy.

Over countless years, countless top-tier beings have reached the peak Saint King realm but have been unable to advance any further; their numbers are countless.

Even with Lin Yun's support and the help of his Blood Prison Sword, it wouldn't be easy for Xia Qingqing, Lin Mengmeng, and Zi Yun to break through to the Divine Realm.

Ultimately, condensing a divine spark is no small matter. It relates to a cultivator's path to enlightenment and so on. Lin Yun was able to easily break through to the Divine Realm because of his past life experience, but Xia Qingqing, Lin Mengmeng, and Zi Yun did not.

However, if they are willing to refine their divine essence and achieve the Divine Realm, Lin Yun can help them quickly break through to the Intermediate Divine Realm right now.

Besides Xia Qingqing, Lin Mengmeng, and Zi Yun, there were also some others who received special care from Lin Yun and had good talent, such as his own sister Lin Duo'er, Lin Mengmeng's brother Lin Jianfei, and his good friend Zhao Gang in this life, all of whom reached the peak Saint King realm.

As long as Lin Yun provides them with divine essence for refinement, they can quickly break through to the Divine Realm.

However, Lin Yun still needs to ask them about this matter. After all, once this path is chosen, one's own path to the Great Dao is essentially severed.

"Qingqing, Mengmeng, Ziyun, congratulations on breaking through to the peak of the Divine Realm." Lin Yun looked at the three women in front of him and smiled.

"Hmph, aren't we amazing! We broke through to the peak Saint King realm so quickly! We even asked Sister Ziyun about it. In the Great World of Living Beings, countless top genius cultivators may not be able to reach this realm even after cultivating for hundreds of millions of years, but we reached it in such a short time!" Lin Mengmeng raised her little fist and "showed off".

"You're right, you guys are really amazing..." Lin Yun laughed, knowing that Lin Mengmeng was joking.

"We also owe a lot to my brother's help and the various environments he created. Otherwise, it would have been very, very difficult for us to cultivate to this level!" Xia Qingqing said with a smile.

"Thank you, my husband..." Zi Yun said softly, her face flushed.

She waited for hundreds of millions of years in the Great World of Living Beings, waiting for Lin Yun through many reincarnations, before finally being with him. Although she spent hundreds of thousands of years in the Netherworld after they established their relationship, it was still too short compared to the time she had been waiting. The time she had actually spent with Lin Yun was also short, leaving her mind still mostly stuck in the past. At this moment, facing Lin Yun as his wife, she was still very shy.

The three women were all stunningly beautiful, and now that they had all cultivated to the peak of the Saint King realm, their temperament was as transcendent as fairies descended from heaven. At this moment, their appearances were different, but all were incredibly alluring. Lin Yun had just completed a stage of cultivation and was relaxing when the women's emotions were stirred.

"Is that so? You first cultivated in the Realm of Living Beings, then in the Realm of the Underworld, and now you've returned to the Realm of Living Beings. You've made such great progress by going back and forth between Yin and Yang. However, it seems you're still lacking an opportunity to harmonize Yin and Yang..." Lin Yun looked at the three women mysteriously and smiled slightly.

"What?"

"What opportunity for yin and yang harmony are we still lacking?"

Xia Qingqing and Zi Yun were both quite simple-minded. When they heard Lin Yun's seemingly serious words, as if he were talking about cultivation, they were both taken aback and subconsciously asked curiously.

Lin Mengmeng was rather clever and mischievous. She noticed that Lin Yun's expression was a bit off, and given her shared experiences with Xia Qingqing, she quickly realized what was going on. Her face instantly turned red, and she playfully punched Lin Yun with her soft fist, saying coquettishly, "Oh, you dare to flirt with the three of us!"

"Um?"

"My husband..."

Xia Qingqing and Zi Yun weren't stupid either. Hearing Lin Mengmeng's words, they quickly realized what she meant. Their faces turned bright red, and they reached out to hit Lin Yun, scolding him, "Husband, you're so improper..."

"My husband, you're so naughty..."

"Hehe, I'm talking about the most proper cultivation techniques, what's wrong with that? Am I wrong? Let me think, how long has it been since we've had a proper cultivation session..." Lin Yun laughed as he dodged the three women's "punches" and continued speaking.

The four of them joked and played around for a while. Soon, Lin Yun waved his hand and pulled the three women into his arms. At the same time, they teleported to a hidden place in the Blood Fiend Universe, where a shielding force rose around them.

I won't go into details about sleeping together under the same quilt, because if I did, it would be censored anyway, and I'm afraid of being censored again.
