Transmigrated into a book? A vicious female supporting character? A senior sister? Tsk tsk!

Following Xiao Bao's voice, Tang Xinyan looked towards the small pool beside him and saw that it was about half full of white lotion in a natural pool the size of a washbasin.

Above the small pool, there is a milky white stone pillar. Clearly, the white emulsion was formed by the accumulation of this stone pillar.

Sensing Tang Xinyan's surprise, Xiao Bao licked his lips, staring at the white lotion with curiosity:

"Sister, what is this?"

Tang Xinyan, recovering from her surprise, explained to Xiaobao:

"This is spiritual essence liquid. Judging from its quality, it is estimated to be at least a thousand years old. The conditions for the formation of this kind of spiritual essence liquid are extremely harsh. I didn't expect to find it here."

At this point, Tang Xinyan had an idea. She released a wisp of lightning power and attacked the cave. Just as she expected,

Not even a trace was left on the cave wall. Tang Xinyan increased her strength and attacked several more times, but the stone wall remained intact.

Having confirmed her suspicions, Tang Xinyan continued:

"This mountain must contain spirit ore, which is why this spirit marrow liquid was formed. However, this spirit ore is also the foundation of this secret realm."

It must have been a powerful figure from the sect who, for the sake of sustainable development, sealed and reinforced the mountain to prevent those who came in for training from completely excavating the secret realm.

As for the spirit essence liquid, I estimate that those who have explored this place, like me, haven't discovered what's inside because of the gaps.

However, it's normal that people don't have a keen sense of smell and wouldn't notice it, but why haven't the spirit beasts here noticed it either?

Xiao Bao chuckled, tilted his head back proudly, and said arrogantly:

"Sister, animals do have very strong senses, like their sense of smell and hearing, but these innate perceptions also have different levels, you know?"

My mother said that our white fox lineage is among the best, and I am the best of the best. This place has nothing...

Normally, spirit beasts don't enter, and the scent of this spirit marrow liquid is extremely faint. I only caught a whiff of it when I reached the cave entrance.

Tang Xinyan suddenly realized and praised Xiao Bao:

"Xiao Bao is amazing! If it weren't for you, I would have missed out on this treasure. In that case, Xiao Bao is comparable to a mouse."

Xiao Bao was overjoyed by the praise, but when he heard that he was being compared to a mouse, he pouted.

"Sister, I'm much better than that silly mouse."

Tang Xinyan knew Xiao Bao's proud and aloof nature, so she quickly smiled and chimed in:

"Yes, yes, yes, my little treasure is the best! My wonderful little treasure, can you help your sister collect the spiritual essence liquid inside?"

Xiao Bao, suppressing his craving, quickly nodded, went out to retrieve the jade bottle Tang Xinyan had given him, and pointed the bottle's mouth at the small pool of water. The jade bottle contained an array.

It can automatically collect the spiritual essence liquid from the pool. After collecting it, Xiao Bao handed the jade bottle to Tang Xinyan and asked:

"By the way, sister, what is this Spirit Essence Liquid for?"

Tang Xinyan carefully put the bottle away and then explained the science to Xiaobao:

"Simply put, this thing is the essence condensed from a spirit ore vein. It contains extremely strong spiritual power and can help people improve rapidly."

For example, with my current cultivation level, I could probably transcend my tribulation by consuming just two drops.

Xiao Bao's eyes widened: "That's amazing?"

Tang Xinyan smiled, took Xiaobao and headed back, saying as she walked:

"Otherwise, why do you think I didn't let you drink it directly? With your small body, you would probably explode and die after just one sip."

Xiao Bao swallowed hard, still shaken. He was incredibly glad he hadn't been so tempted to take a bite, but instead had informed Tang Xinyan first.

Because of this experience, Xiao Bao secretly decided that no matter what he found in the future, he would ask Tang Xinyan first.

The man and the fox had only returned halfway when they received a message from Yu Zechen, saying that his way there was a dead end and he was turning back.

At the same time, he asked Tang Xinyan how things were going and if she had encountered any danger. Tang Xinyan didn't say much, only mentioning that they met at the initial fork in the road.

An hour later, Tang Xinyan returned to the crossroads and sat in a corner waiting for Yu Zechen. She waited for almost three hours.

Just as Yu Zechen appeared at the fork in the road, Tang Xinyan noticed his disheveled appearance and several scratches on his clothes, and quickly got up to ask him:

"You... encountered a monster?"

Seeing that Tang Xinyan was in the same condition as when she arrived, clearly having encountered no danger, Yu Zechen breathed a slight sigh of relief, smiled slightly, and casually said:

"We encountered a few vampire beasts on the road. I knew these things lived in groups, and killing them would be troublesome, so I didn't go all out and just chased them away."

I thought everything was fine, but little did I know, the end of that passage was their lair. I took out some of the ones that attacked first.

Feeling they couldn't defeat that group, they didn't linger and retreated. Fortunately, those guys didn't pursue them relentlessly.

"A vampire? What does it look like?"

Tang Xinyan had never seen this beast before and was quite curious. Yu Zechen thought for a moment and then took out an ancient book with the title "Complete Encyclopedia of Monsters".

Yu Zechen flipped to the page with the vampires and handed it to Tang Xinyan: "Here, this is it."

The book was richly illustrated and described in great detail. After looking at the pictures and reading about its habits, Tang Xinyan had a general impression of it and felt that it looked somewhat like a bat.

He closed the book and handed it to Yu Zechen, but Yu Zechen shook his head.

"Take it and take a look. I've already read this book."

After saying that, he took out two more books, one a complete guide to ferocious beasts and the other a complete guide to spirit beasts, and handed them both to Tang Xinyan. Tang Xinyan didn't stand on ceremony and accepted them, then suggested:

"I see your wounds haven't fully healed yet. Why don't we rest here for a while and set off again once you've recovered?"

Yu Zechen didn't refuse. The two found places to meditate, and after Yu Zechen recovered, they headed towards the central passage.

The journey was peaceful, the passage was long, and they didn't encounter any more forks in the road. It took them almost two days to walk out of the cave.

The cave's exit led to the other side of the mountain range, overlooking a vast swamp and filled with the stench of decay.

Tang Xinyan understood: "This must be the Death Swamp."

Gazing at the faint black mist rising above the swamp, Yu Zechen nodded:

"Yes, according to the information, there is a giant crocodile beast hiding in this swamp. It is huge but extremely good at hiding, especially its sharp teeth."

Even a body cultivator would be either killed or maimed if bitten by this beast. The crucial point is that this giant crocodile beast also carries a peculiar type of small white worm.

They emit a hallucinogenic aura that catches people off guard, leading them unknowingly into the swamp and causing them to lose their lives.

Tang Xinyan pointed to the few scattered red and white wildflowers on the swamp and said thoughtfully:

"Those must be one of the materials for refining the Breakthrough Pill, right?"

Somewhat understanding Tang Xinyan's meaning, Yu Zechen looked around and frowned:
