I, the history teacher, the devil walking in the world Author: Devil Invasion

Bai Chen travels through the ancient period of parallel worlds.

I originally wanted to join the cultivator sect in the novel of the previous life and become a cultivator.

However, he unexpectedly awakens the sign-in system of the demon gods that opposes humans.

In line with the principle of no waves and no death, Bai Chen silently signed in and became a demon god.

Bai Chen, who only wants to develop steadily and live a peaceful life.

According to the system task, become the history teacher of Jing'an No. [-] Middle School, and continue to sign in with the same life as a human being.

By the way, you can easily solve the monsters that disturb your life.

Become a peerless master in the minds of students.

until that day.

The cracks collapsed, and the demons invaded in a big way.

The abyss demon god is invincible and descends into the world.

Only then did the students discover that their teacher was actually a demon!

Chapter 1

Jing'an Base City.

Jing'an No. [-] Middle School.

In the classroom of the third grade ([-]) class.

Bai Chen took the chalk and wrote two words on the blackboard.

"origin."

"Demons are similar to human transcendents."

"The energy required comes from the original crystal nucleus."

"Once the power of the source crystal nucleus is exhausted, the demon will become no different from ordinary beasts."

"Except for the demons known for their defense, other demons cannot withstand conventional thermal weapons."

"This is also the reason why humans were able to resist the invasion of demons [-] years ago."

All the students in the class nodded.

"Teacher, where is the origin of that monster usually?"

A student asked curiously.

Bai Chen raised his head to think for a moment, then smiled.

"The power of the demon's origin comes from its crystal nucleus."

"According to strength attributes, races are different."

"The location of the crystal nucleus is different."

"This needs to be considered concretely."

"Take the recently discovered gold-devouring ants around Jing'an as an example."

"According to everyone's habitual thinking."

"The core of an ant should be the tube attached to its back, which is often referred to as the heart."

"right?"

Gold-devouring ants.

A newly discovered monster in the Jing'an area.

Feed on metals.

The body is as hard as steel.

The body is five meters long, like an armored vehicle.

It caused a lot of trouble to the city guards at the Jing'an base.

Many students nodded.

This message has also been broadcast on the school radio for the past two days.

Students were also warned not to leave the base city to go outside in the near future.

However, what Bai Chen said next surprised them.

"actually not."

Bai Chen roughly drew the outline of a gold-devouring ant on the blackboard.

With chalk, I clicked on its head near the mouthparts.

"The nucleus of the gold-devouring ant is in this position."

While the students were surprised, Bai Chen continued.

"The mouthparts of the gold-devouring ants are as sharp as knives, which can easily destroy the armor of armored vehicles."

"And the source crystal nucleus can only provide energy to it faster if it is close to the mouthparts."

The students suddenly realized that they all nodded subconsciously.

Xia Lingxue is the same.

This is the fourth day that Bai Chen has become their history teacher.

At first, the students in the class were still wondering why they were in the third year of high school, and the college entrance examination was approaching.

Give them a history teacher.

But only two days later.

Including Xia Lingxue.

All the students in the third grade ([-]) class were conquered by Bai Chen.

The new history teacher.

Not only handsome.

The historical foundation is also very solid.

In the past few days, I told them a lot of history about demons that they didn't know.

And just now.

It has even been derived from the body structure of the monster.

I saw Bai Chen smiling on the podium.

A question appeared in Xia Lingxue's mind.

"Teacher, why do you know so much about demons?"

As soon as this word comes out.

The classroom exploded in an instant.

"Yeah yeah!"

"Teacher, the history of the blood flame demon you mentioned before... This blood flame demon, seems to have never been mentioned in the history of demons?"

"Yes! There is also the realm of the devil...the king realm, the emperor realm, etc., have you never heard of it?"

"..."

The students are very confused.

Since the monster invasion more than [-] years ago.

Humans have only encountered three demon disasters in total.

There is no Demon God named Blood Flame.

They have been with Bai Chen for four days.

According to his acting style, he knew that Bai Chen was not a big talker either.

At this moment, all the students in the classroom are staring at Bai Chen intently.

I want to know why Bai Chen knows so much about demons.

"Why do I know so much about demons?"

After a pause, Bai Chen asked himself something.
