Chapter 1023 Green Brick Mountain Range, Past Events

Outside Qiyun Valley, Ye Kang and Lu Cun flew through a massive mountain range stretching for thousands of miles.

This place is called the Green Brick Mountain Range, which is rich in a type of green brick full of spiritual energy, making it extremely suitable for building sect cave dwellings, hence the name.

Ye Kang came here precisely because of the Qi of Heaven and Earth that Lu Cun had once mentioned.

He has been stuck at the Four Qi Perfection stage for some time now, and his cultivation has reached the peak of the Four Qi. He only needs one more Qi of Heaven and Earth to break through.

After all, the goal is to rebuild the Qiyun Sect, so the stronger the sect, the better.

Lu Cun naturally dared not be presumptuous any longer and directly took Ye Kang to the Green Brick Mountain Range.

As he flew forward, he said, "Elder Ye, this place was discovered by chance when I was at the peak of Nirvana, following a senior who had returned to the True Realm. At that time, I was being held hostage by that senior, but after discovering that hidden place, we encountered great danger. That senior who returned to the True Realm was also powerless to resist and was in a situation where he was doomed. At the last moment, perhaps he had a change of heart and risked his life to send me out, and then he perished in it."

Lu Cun was lost in his memories, his expression somewhat wistful.

"Although that senior was fierce, I didn't expect him to save my life at the last moment. If it weren't for him, there probably wouldn't be a Beast Heart Sect. Also, during our exploration, he personally mentioned that there was a first-class Yin Qi of Heaven and Earth, but unfortunately he didn't say the specific name, so that's all I know."

Upon hearing this, Ye Kang nodded: "It's alright, let's take a look first. What exactly makes this dangerous place you mentioned so dangerous?"

Lu Cun frowned and said seriously, "Guarded by a ferocious beast. There is a ferocious beast at the level of a demon saint there. It was already able to crush that senior Guizhen back then. After so many years, its strength has probably improved again."

"Then it'll be fine."

Ye Kang wasn't worried at all; on the contrary, he felt much more relaxed.

He was afraid of some strange rules or puzzles; the simplest scenario was just a ferocious beast guarding the area.

Lu Cun paused for a moment, feeling that Ye Kang was being too confident. He couldn't help but remind him, "Fellow Daoist, that ferocious beast is no simple matter, and being in its lair makes it even more vulnerable..."

"It's alright, just take me there. I guarantee I won't hurt Fellow Daoist Lu Cun."

Ye Kang waved his hand, not caring much.

Lu Cun was worried, but seeing Ye Kang's certainty, he didn't say anything more.

The two traveled for another half a day, venturing deep into the Qingzhuan Mountains.

This place is deserted, and demons gather all around it, so no one but those at the True Realm dares to venture deep in.

Lu Cun pointed to a lake in the forest ahead and said, "This is the place. There is a small cave below the lake, and the ferocious beast is in the lake."

Ye Kang also opened his unfathomable blue eyes and looked carefully.

Sure enough, the lake was filled with a menacing aura and a strong smell of blood.

Clearly, some big guy has just had a big meal.

Just then, the system notification sounded.

【Ding】

[Task issued by: Tiger Fish Blood Shadow]

[Mission Requirements: Defeat the ferocious tigerfish and obtain the Nether Lotus Ink Bone Qi]

[Task Reward: 8000000 Comprehension Points]

"Ok?"

Ye Kang's expression immediately became interesting; the task issued by the system contained quite a lot of information.

First of all, the Qi of Heaven and Earth exists, called Youlian Mogu Qi, a kind of Qi that I have never heard of before.

Secondly, the task rewards seem a bit too much.

Could it be that the tiger-fish beast is not so simple?

Ye Kang knew about the tigerfish; it was a ferocious beast with a violent temperament, seemingly a ruler whether in the water or the forest, possessing extremely powerful innate bloodline.

Such a bloodline is extremely rare in the world, and I never expected to see one here.

Just as Ye Kang was pondering, countless blood-red water vapors suddenly rose from the lake, evaporating into the air and forming a beastly shadow.

The boundless surge of blood energy instantly chilled Lu Cun to the bone.

"It's out!"
