Yan Mo's hand was suddenly shoved with a glass bottle containing a rat, and his face immediately turned deathly pale.

She was very puzzled by Xiaoxi's actions, but Xiaoxi pretended not to see it.

Yan Mo could only look to Bei Chen for help.

Bei Chen saw that Xiao Xi insisted on doing this, so he didn't dare to say anything, but he felt extremely sorry for her.

Xiaoxi pretended not to see anything and they went to a large, undeveloped wasteland behind the teaching building.

Bei Chen seemed to have made a very big decision.

He suddenly said, "I'm sorry, Teacher Yan, I haven't told you the truth all this time. I am actually Shenlong."

"What?" Yan Mo didn't hear clearly.

Bei Chen raised his voice: "I said I am actually an ancient divine dragon."

Yan Mo was completely dumbfounded. She didn't understand why Bei Chen would joke at this time.

Xiao Xi laughed out loud, "Teacher, what Bei Chen said is true. In fact, we are the invincible demon hunters in the universe!"

Then she immediately proved everything with her actions.

"Bei Chen, transform!"

Bei Chen suddenly disappeared, and a huge black dragon appeared in the open space.

"Let's go, teacher, let's not waste any more time." Xiaoxi pulled the utterly shocked Yan Mo onto the dragon's back.

Yan Mo was about to scream when she remembered that she had just promised Xiao Xi not to make a fuss.

She just kept holding back, then awkwardly tried to make conversation.

"We're making such a commotion, we shouldn't let the other students see us."

"Don't worry, teacher, I have a way."

Xiao Xi took out an invisibility talisman, which not only made them invisible, but also concealed Xiao Xi and Bei Chen's auras so that they would not be discovered.

The dragon soared into the sky, and Yan Mo was so frightened that she clung tightly to Xiao Xi, not daring to make a sound.

Xiao Xi also admired Yan Mo's composure. She felt that Bei Chen's flight speed was very slow and gentle, which showed how much he cared for his wife.

They flew into the air and entered the smog, and Xiaoxi felt that she had difficulty breathing.

To alleviate her fear, Yan Mo tried her best to talk.

Xiaoxi couldn't take it anymore.

"Teacher, don't you feel like you're having trouble breathing? And it's very windy in the sky, so try not to talk too much."

Yan Mocai felt a little embarrassed.

"Xiaoxi, actually I'm quite scared. Only talking can distract me. Hmm, there are so many particles in the air."

Xiaoxi was puzzled. How could the teacher see these particles?

At that moment, I sensed a familiar demonic aura, the same kind of demonic aura found in New Year's paintings.

So this smog is the evil demon?

Xiao Xi immediately told Bei Chen to stop.

Beichen remained still in the air, and at that moment there was not a breath of wind.

Xiao Xi took the bottle from Yan Mo's hand, opened the cap, and the mouse inside immediately scurried out.

The mouse thought it was escaping, but it was actually courting death.

Right on Yan Mo's leg, the rat was sucked dry by countless tiny particles that suddenly gathered around it.

Yan Mo felt extremely nauseous. Instead of crying from fright, she kept gagging and shed physiological tears.

Xiaoxi was surprised to find that her teacher's tears could actually purify the demonic energy of these particles.

Oh, I almost forgot, the teacher is an adorable bunny, from the ancient rabbit clan.

It must be because her heart is pure that her tears can purify the demonic energy.

No wonder she could see the particles just now.

The specific reason can be asked of Bei Chen when they return to the ground; he knows his wife.

Xiaoxi quickly filled a glass bottle with some unpurified particles, and then put a drop of the teacher's tear into the bottle.
