In the remaining days, Su Tu and Le Yiwen continued their research in the laboratory, repeatedly simulating and altering the Third Realm and Fourth Realm.

However, tracing back against the martial arts lineage that has spread throughout the universe is no easy task.

The two failed time and again, unable to find a way to fuse the two realms together.

"Forget it, Junior Brother, this matter is too difficult, obscured by the Martial God, we simply can't see through it."

"With your talent and aptitude, there's no need to worry. Even if you follow the current path of martial arts cultivation, your future achievements won't be low."

Le Yiwen advised.

Su Tu's eyes narrowed, filled with intense unwillingness.

What's missing...

What exactly is missing in the cultivation steps that the Martial God has more of...

Unable to think of it, unable to find it, the two had deconstructed every step of cultivating the two realms over the past few days, reducing them one by one, but no matter which step was missing, the cultivation couldn't proceed.

This seemingly dismantled perfect cycle, after transforming into two realms, reached a new perfection, with any missing step causing the originally constructed martial arts tower to completely collapse.

"Stop thinking about it, let's go out and take a walk, get some fresh air; we've been holed up for days."

Le Yiwen joked.

Although the two had been eating, drinking, and sleeping in the laboratory these days, it wasn't as unbearable as Le Yiwen joked. The laboratory had all facilities completely equipped, with many rooms just for sleeping.

By the way, Su Tu originally thought that Le Yiwen's workshop was unique to the Celestial City Star, but in fact, Le Yiwen had one or several such workshops on all the main stars.

It was an unmistakably large household.

According to Le Yiwen, while researching plants and parasites before, he accidentally obtained an interstellar-level patent...

Accidentally...

Patent...

This was the first time Su Tu heard something similar, beyond martial arts, that mirrored his own inexplicable words.

At that moment, he shared a small connection with Luo Fan and others.

However, Le Yiwen's words held some truth. Even holed up like this, nothing new emerged from the research; what needed to be done, and tried, had all been simulated.

At this point, it could truly be said there was no solution left.

Might as well refresh the mind.

So, the two left the laboratory, and looking at the glaring sunshine outside, Su Tu felt a sense of being in another world.

No wonder those highly accomplished scientists and scholars are not very communicative, having been holed up for just a few days, the outside seems a bit alien.

And for those scholars and scientists, conducting experiments day and night in such an environment, it's amazing they don't go insane.

"What do you plan to do?"

"Go back and pack things up, I have to leave tomorrow."

Today was already the fourth day, and in three days, it would be the opening of the general exam. Su Tu had to catch the quickest flight back to Ancestor Star tomorrow.

"Alright, don't forget our agreement." Le Yiwen reminded.

"After some time, once your general exam is over, I'll also visit Ancestor Star. It's been a long time since I saw Master."

Su Tu nodded in agreement, then returned to the previous hotel. Although he said he wouldn't think about it anymore, in reality, Su Tu was still occasionally contemplating possible attempts.

Until he returned to the room.

Su Tu heaved a long sigh: "I can't think anymore, my thoughts are becoming rigid."

He realized his condition was off, like the first time tackling an Olympiad math problem, facing an overly challenging final bonus question, no matter how much he thought about it, he couldn't solve it.

It even once caused his problem-solving approach to become rigid, almost unable to solve even ordinary problems.

Now Su Tu had finally completely freed himself from that state.

Not thinking about the mystery of the two realms anymore, Su Tu only felt a lightness and freedom in his heart.

[You broke free from Heart Demon Obsession, Candle Wisdom Proficiency +500!!]

[Candle Wisdom (Middle Tier): 8200/20000]

Seeing this notification pop-up, Su Tu's eyes widened, his whole body's hair stood on end.

Unexpectedly, due to his fixation on the mystery of the two realms, he had fallen into Heart Demon Obsession.

The so-called Heart Demon Obsession is a calamity affecting the heart and spirit caused by excessive obsession, silently eroding the heart and spirit. When deeply obsessed, it can lightly damage the martial artist's heart and spirit, and at worst, transform the heart into a demon, leading to insanity.

Reflecting on it now, his condition the past few days indeed wasn't right, no wonder his senior brother kept reminding him.

At this moment, looking at the notification, Su Tu couldn't help but smile wryly.

Since entering martial arts, he had weathered no small number of storms, handling them not perfectly but adequately, yet he nearly stumbled due to obsession.

This made Su Tu learn a lesson.

"Too much is as bad as too little, go with the flow."

Su Tu adjusted his heart and spirit, repeated his words several times, and then formed the Heaven-Flipping Seal's finger seal, finally calming himself fully.

This path, he would not give up seeking, but he would not be too tight or too loose.

After a while.

Su Tu finally adjusted himself to the optimal state, then undressed and took a cold shower, regaining his former high-spirited demeanor.

Stepping out of the bathroom, while dressing, he saw a Black Wood Waist Token and suddenly realized it.

He thought about how these recent days, there was always a feeling of forgetting something.

During the retake, he had killed fifteen Heart-faced Beasts and one Beast King, which provided Su Tu with a large amount of battle merit. He had originally planned to exchange rewards at the Battle Merit Wall.
