After her senior sister was reborn, she actually became a powerful and arrogant protagonist?!

Southern Xinjiang, the Tie family courtyard.

Gu Lin was intently studying the formation in front of him.

"Using powerful Gu worms as the core of the formation, and then placing various sub-Gu worms to connect key parts of the formation..."

"Although it's not as stable as those fixed materials, it's extremely flexible now."

"The core of this formation can constantly change positions with those sub-Gu worms, which is indeed a good formation."

Gu Lin was studying the material while muttering to himself, completely absorbed in it.

Completely unaware, Xun Nan, who had been silently standing behind him, had disappeared without a trace.

"The next step is to remove the last sub-Gu worm to completely isolate the core Gu worm."

"Even if it is demolished by force, it will not affect what is hidden inside."

As Gu Lin spoke, he wiped the sweat from his forehead, his eyes filled with delight.

He hadn't encountered anything this challenging in a long time, and he felt a surge of exhilaration.

Why hasn't Chu Luobai returned yet?

Gu Lin looked up into the distance, about to turn around and ask Xun Nan to check the situation.

But they found that there was no one behind them, and the whole courtyard was quiet.

"Xun Nan took the antidote and ran away? I'll have to tell Fellow Daoist Chu later that men are all prone to hypocrisy."

"Male concubines are no exception."

Gu Lin couldn't help but make a sarcastic remark before turning back to continue working on the formation, decisively crushing the last sub-Gu worm.

At the moment the Gu worm died, the ground suddenly shook.

The violent tremors swept through the entire Tie family estate in an instant, and the ground shattered into pieces as if a mirror had been smashed on the ground.

The deep, bottomless ravines resembled the gaping maws of a giant beast.

Those servants of the Iron family who wanted to plunder more lost their footing and fell into the bottomless abyss.

"How could this be? What trap did I run into?"

Gu Lin subconsciously thought this, and his body quickly floated into the air.

From afar, he could see Chu Luobai floating in mid-air, just like him.

The tremor was quite extensive, encompassing almost the entire Tie family compound and the mountain behind them.

"The Tie family's mountain-protecting formation?"

Chu Luobai looked on, feeling somewhat puzzled.

She flew to a stop beside Gu Lin, watching as the ground trembled more and more noticeably, and the cracks on the ground continued to deepen.

What mechanism did you trigger?

Chu Luobai asked subconsciously, "If it's a mountain-protecting formation, then Tie Ao and Tie Tian should have activated it when they were on the verge of death."

How could they wait until both of them were dead before opening it?

Isn't this like taking off your pants to fart?

"That shouldn't be the case; I've been very careful with every step I take."

Hearing Chu Luobai's question, Gu Lin felt somewhat frustrated and couldn't help but frown and ponder.

"Although this formation is complex, it is clear that the person who set it up was very arrogant and did not leave any backup plan."

"I don't think this earthquake has anything to do with that formation."

As Gu Lin spoke, he met Chu Luobai's questioning gaze, and his confidence inexplicably waned, even his tone became weaker.

"Is that still the mountain-protecting formation?"

Chu Luobai voiced his guess, "But neither Tie Ao nor Tie Tiansheng activated it before they died. What's the point of activating it now that they're dead?"

"Besides, all the direct descendants of the Tie family are dead, so who would know about the Tie family's protective mountain formation..."

Before he could finish speaking, Chu Luobai's eyes flashed, as if he had suddenly realized something.

His gaze instinctively drifted downwards, searching for Xun Nan's figure amidst the chaos.

"Xun Nan ran away?"

Chu Luobai released her divine sense, and Xun Nan's presence was long gone from the vicinity.

"They run pretty fast..."

"If I were him, I would have run away the moment I got the antidote."

Gu Lin raised an eyebrow and looked into the distance. In the dense forest to the southeast, there were still traces of Xun Nan's presence.

"I guess this earthquake is your little male concubine's 'return gift' to you."

Chu Luobai could hear the suppressed laughter in Gu Lin's tone. If the other party didn't also have some knowledge of pills, Chu Luobai really intended to feed him a poison pill as well.

"There's nothing we can do about it; some men are indeed petty and narrow-minded, but that can also be a kind of fun."

Chu Luobai turned to look at the ground, her tone somewhat mocking as she retorted to Gu Lin.

"Just consider it a little temper that's been building up from my travels in the south these past few days."

“…”

Seeing that Gu Lin didn't know how to respond for a moment, Chu Luobai's lips curled up slightly.

Gu Lin may not actually think that Xun Nan is his so-called male concubine; he just wants to find an excuse to tease himself a bit.

Now that I'm no longer embarrassed, the one who's embarrassed is someone else.

The ground tremors have gradually subsided, and the huge cracks have almost swallowed up the entire Tie family.

A faint red light emanated from the depths of those cracks.

The red light grew brighter and brighter, instantly filling Chu Luobai's entire field of vision.

Amidst the red light, thick branches sprouted from the depths of the crack, rapidly growing into a towering giant tree.

"This tree looks familiar."

Chu Luobai stared at the giant tree as it rapidly grew into its current form, feeling that it looked somewhat familiar.

"Another Blood God Tree?"

This tree looks very similar to the Blood God Tree I encountered in the Autumn Kingdom, except that its branches and leaves are somewhat different.

Previously, the Blood God Tree of Qiu Kingdom had the most ordinary branches and leaves, but the branches and leaves of this tree are more like the drooping branches of a willow tree.

The leaves are green on the inside and red on the outside, with the red color becoming more pronounced towards the edges.

It's like the bloodstains left after a sharp knife cuts someone.

The roots beneath the giant tree did not stop growing; instead, they continued to extend outwards.

Those members of the Tie family who had escaped the calamity by not falling into the cracks had no time to celebrate before the tree root pierced through their chests.

Warm blood gushed from their chests, splashing onto the tree roots, where it was instantly absorbed.

Chu Luobai frowned as he watched this scene.

"Could this Blood God Tree be the mother tree from the one in Autumn Kingdom before?"

"possible."

Gu Lin replied, his expression also somewhat unpleasant. He could sense that the bloody smell emanating from this Blood God Tree was far stronger than that of the one in Qiu Kingdom.

Clearly, the Tie family has been 'nurtured' for many years.

After absorbing the remaining members of the Iron Clan and the corpses on the ground, the willow branches of the Blood God Tree began to sway.

It was as if countless venomous snakes had their eyes on Chu Luobai and Gu Lin.

Suddenly, several willow branches shot out and rushed towards Chu Luobai.

Clang!

The celestial bell collided with these willow branches, producing a piercing, metallic clang.

"So hard?"

Chu Luobai was so shocked by what she saw that her right hand went numb, and she murmured in surprise.

The immense force forced her to retreat a short distance.

Without pausing, the willow branches attacked Chu Luobai once more!
