There was no expression on Tian Yongheng's face. He was calm, indifferent, just as always.

However, inwardly, a tide of emotions surged through his entire being, threatening to tear apart the Dao Heart forged over six centuries of diligent cultivation.

That girl whom he had seen grow up in his past life, making sure she always stayed away from harm like a responsible older brother, how much had she suffered since that incident?

He couldn't even dare to imagine, only feeling a pang of extreme guilt and self loathing.

If only I was a little stronger, if only I hadn't died at that time...

Perhaps things would have been different. But it was no longer the case now.

It had been over 600 years.

Countless things had changed, including his own mindset as a result of his cultivation base.

Yet, even then, he still couldn't shake off this wave of self blame.

In the first couple of decades after regaining his past life memories, others may not know, but he had also lived a difficult life, enduring extreme loneliness, with no one to rely on.

At that time, had he not quickly become a Acupoint Opening Stage cultivator because of the system awakening, he would have already been robbed and killed by mortal bandits when wandering into he secular world.

At that time, he truly felt how those who had no one to rely on and were weak survived in this world. The point was, most didn't. They had to adapt and become stronger, forge connections, and do countless other things just to survive.

Only after reaching the Qi Condensation Realm did his mindset settle and improve slightly, capable of enduring years of loneliness in seclusion without breaking down or going mad.

He couldn't imagine how his younger sister, who was way less experienced than him in the ways of the world back then, had managed to endure and survive for so long.

He at least had the system to rely on, with his overpowered talents, he could cultivate extremely fast, leaving behind his peers in dust, achieving in just a hundred years what most couldn't in a thousand.

Without any such support, how was she living now?

It had been a long time since Yao Qiuyue reincarnated, was his sister even still alive at this point? Had she broken through to a higher realm to obtain a longer lifespan? How was she doing after their master's death?

Countless questions surged in Tian Yongheng's mind, yet no answers emerged.

Even now, he didn't have any backing, with only the system providing some assistance here and there.

He didn't want to think how his sister was doing right now. He wasn't qualified to. His cultivation base was too insufficient. He couldn't even leave the Lower Realm.

How was he supposed to do anything when he himself was in constant danger?

If she had just managed to live till now after her and Yao Qiuyue's master's demise even without any cheat abilities or backing, he could just hope that she could continue living until the day he was powerful enough to sweep away everything and go back to earth.

Perhaps that day was still too far away, but he had hope that he could definitely achieve it one day.

No, he had to achieve it at all costs.

At that time, even if his parents, his old, true friends, and his sister had all long since entered the Six Paths of Reincarnation, he could still pull them out with pure, raw strength.

Time... was still what he needed the most right now.

After the initial surge of emotions, he finally composed himself, his mental state clearing once again. As an Immortal Ascension Realm being, it was hard to truly collapse his mental state, so he wasn't overwhelmed by his emotions even now.

He turned to look at Yao Qiuyue once again, and unconscious, his gaze, although still as composed as ever, seemed to have softened just a little.

"Thank you... for bringing me this information."

As soon as he said this, Yao Qiuyue's eyes flickered with an unknown emotion. She understood at that point. She had found the right person.

[Yao Qiuyue's favorability towards you has increased.]

[Current favorability: 4-Star]

Tian Yongheng flicked his finger, a Communication Jade appeared in his hand as he tossed it to Yao Qiuyue.

"This Communication Jade was modified by me and contains a trace of my power and comprehension of natural elements, worldly laws, and heavenly rules. It can be used to unleash a strike that should be invincible under the Immortal Realm 3 times, and you can also use it to comprehend the natural elements and worldly laws to further perfect your cultivation and understanding of all the realms till the Void Refinement Realm. It will also help you comprehend the heavenly rules after reaching the Nascent Soul Realm."

Tian Yongheng paused for a moment before adding, "This is one of the only ways I can repay you for going through the trouble of coming to the Eternal Peak and informing me about the situation on earth. Since you're my younger sister's fellow disciple and also come from the modern world, there's no need to be formal between us."

His voice was neutral, yet it sounded like a divine decree in Yao Qiuyue's ears.

She held the Communication Jade in her hand, looking down at it with complexity. She could sense Dao rhymes flowing around the jade.

High level cultivators produced Dao rhymes when cultivating, which was immensely beneficial for lower level cultivators, specially those who had not yet grasped the power of the heavenly rules.

Dao rhyme could instantly pull those cultivators below the Nascent Soul Realm into a state of enlightenment, while even for those cultivators above the Nascent Soul Realm who had comprehended the heavenly rules, they were still a great opportunity, giving them a better understanding of the heavenly rules.

For a genius like Yao Qiuyue, she had already begun to comprehend the heavenly rules just at the Void Refinement Realm.

Although she could ask her master and the other seniors of the Ice Mystic Holy Land for guidance or even let them bestow upon her the blessings of Dao rhyme, in the end, it was different from Tian Yongheng.

After all, not only was Tian Yongheng publicly recognized as the strongest being in the entire world right now, capable of cutting down even an Immortal God, she also knew that he wasn't even yet a thousand years old.

The pointers an unparalleled genius like him could provide were incomparable to others.

For an ordinary person, perhaps a genius providing guidance was not of much help because they simply couldn't understand each other's perspective, but for two geniuses, although clearly not on the same level, it was still extremely beneficial.

This was exactly the case with Tian Yongheng and Yao Qiuyue.

Even more importantly... This Communication Jade contained a trace of the unfathomable power of Tian Yongheng, and it could even be used 3 times. It was no different from 3 life saving trump cards.

She had personally witnessed his power back at the Isle of Heavenly Demons, and even her master at that time told her that he probably couldn't last under that strike even if it was weakened by several times.

With such a powerful life saving method in hand... Couldn't she walk unhindered in the entire Second Great Mortal World?

"Is there... anything else you want to know that happened after you reincarnated?"

She quietly asked.

After all, now that they knew eachother's identities and could even be considered old acquaintances coming from the same world, their guard, although not completely down, still naturally eased a lot around eachother.

A glint flickered in Tian Yongheng's eyes as he spoke the next moment, "Do you happen to know anything about a person called Ye Fan?"

As soon as Yao Qiuyue heard that name, it was as if a loud thunderclap echoed across her entire being, sending a wave of murderous intent throughout her.

"Was he the one who killed you, too?"

"You too?"

So we have a common enemy...

Tian Yongheng was inwardly stunned before he let out a quiet sigh.

Fate was truly an enigmatic force.

Perhaps the reason Yao Qiuyue transmigrated into the Second Great Mortal World was also because of this so-called fate.

"He was already a Foundation Establishment cultivator at the time of my death... I couldn't resist at all."

Yao Qiuyue spoke quietly, sighing in the end.

"I was killed by him before the Age of Spirit Recovery. He was already a Acupoint Opening Stage cultivator at that time."

Tian Yongheng admitted as well, causing Yao Qiuyue to look at him with a somewhat dazed expression.

"Does that mean... He got a certain opportunity? There should have been no Immortal Cultivators on earth before the Age of Spirit Recovery, at most those ancient Martial Artists who are comparable to the Acupoint Opening Stage."

She finally asked, her mind reeling with the implications behind this newfound information.

"Perhaps... the Age of Spirit Recovery on earth also wasn't as simple as I initially thought."
