At the same time, Li Lin also sighed inwardly. The energy from that miraculous energy body was truly immense and terrifying. If an ordinary martial artist were to devour it, their strength level would likely climb even higher.

Because his dantian Qi sea was much larger than that of an ordinary martial artist, the energy needed for a breakthrough was also much greater. If his dantian Qi sea was the same as that of an ordinary martial artist, he probably could have broken through to above the sixth level of Martial Soul.

Moreover, within this miraculous energy body, half of it turned into spiritual power. If it had all turned into Qi, he probably would already be at the eighth level of Martial Soul.

"What a terrifying and miraculous energy body." Li Lin exclaimed. This energy body was left by some strong being from the past, but it must have been at least a martial artist and spiritual practitioner. Otherwise, it wouldn't have been possible to separate spiritual power from it.

"Lin'er, are you dual cultivating spirit and martial arts?" After seeing Li Lin's breakthrough, Cui Yu's voice came over, full of absolute astonishment.

"Could you keep it a secret for me?" Li Lin turned slightly, looking at Cui Yu, as his recent breakthrough had unavoidably revealed his dual cultivation identity.

"Mm... I won't let a second person know." Hearing Li Lin's tacit agreement, Cui Yu's beautiful eyes flashed with absolute astonishment, then she slowly nodded in response.

"Thank you. I don't want to reveal my dual cultivation yet." Li Lin spoke softly. Although he didn't trust Cui Yu 100%, he did trust her 99%. Given Cui Yu's character, if she promised something, it likely wouldn't be disclosed.

"When you were on the Dragon Peak and faced Huang Hu, who ranks thirty-sixth on the Dragon List, you must have used a spiritual technique to defeat him in one move, right?" After her surprise, Cui Yu asked Li Lin. Back at Dragon Peak, when Li Lin defeated Huang Hu in one move, she felt the fluctuation of spiritual power on Li Lin but didn't think of dual cultivation at that time. After all, even she had never seen a dual cultivator of spirit and martial arts.

"Mm!" Li Lin nodded, admitting that when he defeated Huang Hu, he had used the Illusory Spirit Imprint combined with martial techniques, which had a surprisingly good effect.

"Then, back in Qingyun Town, were the pills you made all refined by yourself?" Cui Yu asked again.

"Indeed, it was not easy to clear the debt I owed you." Li Lin said with a smile. The debt of over eight thousand gold coins had weighed on him like a mountain, but now, he wouldn't feel the same pressure even for eighty million or eight hundred million gold coins.

"Let's look around and see if there's anything special in this hall. If the miraculous energy gathered here, it's likely there are some oddities inside," Cui Yu said.

The two then searched inside the hall. The area of the hall was quite large, spanning hundreds of square meters, with some disorder around, cracked walls, and many stones fallen on the ground.

Around the hall, there were several inner rooms similar to chambers. After searching the hall twice with their minds expanded, they found nothing. After looking at each other, they moved to the rooms on both sides of the hall to search.

These rooms were also empty and dilapidated, with cracked walls and covered in dust, looking completely like an ancient house of ten thousand years. After carefully searching the nine rooms twice, they still found nothing.

"Nothing at all." The two returned to the hall disappointed, having searched carefully but found nothing.

"It looks like this is just a remnant left by a strong being's battle, nothing special. Perhaps this was originally a residence of a strong being, but after being killed by another strong being, it was looted, leaving only remnants," Cui Yu spoke lightly.

Li Lin also sighed slightly. It was evident that there had been a battle here, and perhaps Cui Yu was right, if there were treasures, they had been taken by others. The place was empty, but being able to improve his strength significantly here was still a considerable gain.

"Let's go, we should find a way out first," Cui Yu said.

"Let's go." Li Lin spoke lightly, sighed slightly, and with a flash of Qi under his feet, he kicked a piece of broken stone, which then hit the wall with a clang. Then, Li Lin was about to walk out of the hall.

"Eh." At this moment, Li Lin's soul probing detected something unusual, not with the broken stone, but he unintentionally felt that the Qi he released under his foot was dispersing towards a corner of the hall at a slow and invisible speed.

With his soul probing, Li Lin had a premonition that he was about to discover something. Following the direction where the bit of Qi was dispersing, Li Lin's gaze fell on a wall with several cracks.

Inside the cracks, there appeared an object the size of a thumb, which Li Lin then picked up.

The object was covered in a thick layer of dust without any energy fluctuations, making it indistinguishable upon close inspection.

The object was shaped like a mini knife, as light as if it weighed nothing.

"Whoosh whoosh..." Li Lin blew on the object, and the dust on it was blown away, revealing a faint golden glow. It was a small knife, with the blade showing a golden color but looking very dim, with several irregular shallow marks, seemingly secret patterns.

"What is this?" Cui Yu came over to Li Lin's side, looking at the small knife in his hand and asked.

"I don't know, it seems to have nothing special." Li Lin spoke softly, probing with his soul, but the small knife seemed to be just an ordinary object without any space inside or any energy fluctuations coming from it.

"Try dripping blood to recognize it as master and see if there's any reaction," Cui Yu suggested.

Li Lin formed a hand sign, and a drop of blood from his index finger fell onto the golden knife. The blood flowed and swayed on the blade, and after a moment, it seeped in.

"Still no reaction." Watching the golden small knife in his hand, the blood seemed to have seeped in, but a blood mark remained on it and did not completely penetrate.

At this moment, the golden small knife remained calm, without any reaction.

"It seems to be just an ordinary item, nothing special." Li Lin smiled bitterly. The golden small knife probably wasn't a treasure, without any aura or energy fluctuations, it didn't seem related to any treasure.

"Let's go, we need to find a way out quickly, hoping not to get trapped here," Cui Yu spoke lightly.

Looking at the golden small knife in his hand, Li Lin was about to throw it away but then thought it would be nice to keep it as a souvenir, so he put the golden small knife into his space bag.

Li Lin's storage ring had never been exposed in front of others, so when collecting items in front of others, he used the space bag on his body.

At that instant, Li Lin didn't see that the blood he dripped on the golden small knife had completely seeped in, and the red blood mark also disappeared.

After leaving the dilapidated palace, they continued to the square, looking around, Li Lin said, "I don't feel like we're in a formation anymore, could the formation have been broken?"

Above, the sky was grey, and Li Lin felt this space was no different from other spaces in the secret land.

"There seems to be only one direction to go out. Let's try it," Cui Yu spoke lightly. On the square, surrounded by mountains, only a canyon extended out in the middle, and the huge building's ruins were in the center of the deep valley.

"Let's go, it's worth a try, anyway, we have no other choice," Li Lin spoke lightly, and they both leapt forward.

They walked forward carefully, not daring to be careless, but no danger appeared.

"Eh, we're out." Half an hour later, guarding their surroundings cautiously, they walked out of the canyon and found themselves in a familiar place.

"This seems to be the dense forest we originally entered." Cui Yu looked at the scenery in front of her with surprise and said. After walking out of the canyon, they found themselves in a dense forest, precisely the one they entered while escaping from the two-headed water-fire demon jiao.

"Forbidden area." Li Lin looked around and saw the words "Forbidden Area" written on a towering tree. Sect Master Yun Xiao Tian had said that places marked as forbidden areas should not be entered. In their haste to escape from the two-headed water-fire demon jiao, they had carelessly ignored the warning.

"Lin'er, the canyon has disappeared." Cui Yu's surprised voice came to Li Lin's ears. When Li Lin turned back, he found that the canyon they had just walked out of had disappeared, as if it vanished into thin air.

"Boss, you finally came out, you had me worried to death." Just as Li Lin was surprised by the disappearance of the canyon behind him, the voice of the little dragon came out in his mind.

"Whoosh whoosh..." A yellow streak of light flashed like lightning and landed on Li Lin, which was the little dragon.

"Little Dragon, are you okay?" Li Lin immediately asked, as he had been worried about Little Dragon.

"How could anything happen to me?" Little Dragon's round little eyes spun, and he affectionately licked Li Lin's face.

"Sss sss..." At this moment, a demon beast several meters in size crawled out, its body covered in blue and red scales, and each of its two heads had only one giant eye, staring at Li Lin and Cui Yu.
