Half an hour later, Meng Fei took Professor Zhao and the other two up the mountain.

As Li Wentao did not get enough rest last night, Professor Zhao called him several times but he refused to get up, so he simply left him at home to look after the house.

After entering the mountain, Professor Zhao and his companions were full of curiosity about everything around them.

They were terrified when they went into the mountains before, but this time with Meng Fei around, they felt a lot more relaxed.

Meng Fei looked around as he walked, and soon he found a plant with small purple flowers and leaves covered with thorns.

Meng Fei hurriedly walked up to it, pulled out the short blade from his waist and dug it out.

When Professor Zhao and others saw Meng Fei squatting on the ground busying himself, they all came over.

"Meng Fei, what is this? Is it also a herb?"

Meng Fei smiled and explained, "We call this Cirsium arvense, and its scientific name is Cirsium arvense. It has the functions of clearing away heat and detoxifying, reducing inflammation, stopping bleeding, and promoting cell regeneration. It is very suitable for your research."

After listening to Meng Fei's explanation, Professor Zhao's eyes lit up.

He quickly took the prickly lettuce from Meng Fei's hand and held it in his palm as if it were a treasure.

Meng Fei then found several more shells nearby, dug them all out and put them in his pocket.

After that, the few of them wandered around in the mountains for another morning, and under the leadership of Meng Fei, they collected a lot of Chinese herbal medicines that have hemostatic and anti-inflammatory effects.

But what made Meng Fei depressed was that he never found any trace of the horse dung bag.

"That shouldn't be the case. There are the most horse manure bags in this season. We can often see them in normal times."

Just when Meng Fei was feeling depressed, Yang Jin, the only girl in the team, suddenly let out a shrill scream!

She lost her balance and slid rapidly down the steep slope!

Meng Fei's heart tightened and he ran over quickly without thinking too much.

When he rushed to the bottom of the slope, he saw Yang Jin lying on the ground, his hands tightly covering his ankles, his face as pale as paper, in great pain, and he kept moaning...

Meng Fei quickly checked his ankle and after repeated confirmation, he breathed a sigh of relief.

"Phew~ Don't worry, there's no bone damage, it's just a common sprain. It will be fine after a week of rest."

Yang Jin sobbed hard for a few times before she calmed down. However, feeling the pain in her ankle, the girl couldn't help crying in grievance.

Meng Fei was somewhat helpless when he saw this......

At this time, Professor Zhao and the other person also hurried down the slope.

"Yang Jin, are you okay?" Seeing Yang Jin holding his ankle tightly, the young man hurriedly came up to him and asked anxiously.

"Hmph! By the time you came down to save me, I was already exhausted!" Yang Jin wiped her tears, turned her head away, and ignored the young man.

Meng Fei and Professor Zhao smiled at each other.

There seems to be something going on between these two people...

However, at this moment, Professor Zhao's gaze inadvertently swept across the tree stump behind Yang Jin.

I saw more than ten things of different sizes, shaped like steamed buns, growing next to the tree stump.

Some of them had turned black and had cracks on them.

Professor Zhao's eyes lit up and he quickly called Meng Fei who was standing beside him.

"Meng Fei!!! Look, is that a bag of horse manure?!"

Looking in the direction of Professor Zhao's finger, Meng Fei was also very excited.

"Yes! That's the bag of horse manure."

This is really a case of searching for something without any effort, but finally finding it!

Hearing Meng Fei's affirmation, Professor Zhao ran forward excitedly, but perhaps because he was too excited, he fell several times along the way.

But even so, Professor Zhao did not slow down at all and rushed towards his granddaughter's hope.

Professor Zhao held a freshly picked horse dung bag in his trembling hands, and tears instantly wet his eyes.

"Found it...finally found it..." Professor Zhao's voice choked as he carefully put the bag of horse manure into the bag.

Meng Fei quickly stepped forward to help Professor Zhao up and asked with concern: "Professor Zhao, are you okay?"

Professor Zhao shook his head with a relieved smile on his face: "I'm fine. As long as I can find the horse manure bag, everything will be worth it."

When Yang Jin saw Professor Zhao found the bag of horse manure, he forgot about the pain in his feet and shouted excitedly, "Great! Xiaoya is saved now!"

At this time, the young man in the team also walked up, and when he saw the two black horse dung bags on the side, he reached out to pick them curiously.

"Slower!"

Before Meng Fei could finish his reminder, the young man's big hand had already taken off the bag of horse dung.

"Huh? Why is there a hole on it?" The young man picked up the black horse dung bag and prepared to put it in front of his eyes for a closer look.

But the next moment, his fingers exerted a slight force.

"puff!!!"

A black smoke suddenly erupted from the horse dung bag, covering the young man's head.

"Cough! Cough! Cough! What the hell is this! Cough!"

Seeing this scene, Meng Fei couldn't hold it in and burst out laughing.

"This is a mature horse dung bag. When it matures, the inside of the horse dung bag will gradually turn into dust. These dusts are its spores, which will be spread to other places by the wind. You don't have to worry. The spores of this horse dung bag are also a kind of traditional Chinese medicine. They can clear away heat, relieve cough, disinfect and reduce inflammation."

After hearing Meng Fei's explanation, the young man wiped the dust off his face awkwardly, and as if nothing had happened, he continued to help the professor collect horse dung bags.

After everyone finished collecting the materials, they found several piles of horse manure nearby.

Finally, the backpack could no longer be packed, so I gave up.

On the way back, because Yang Jin's ankle was injured, Meng Fei kindly wanted to carry her back, but was objected by the young man.
