This spirit rune wasn't too complex. But because it was drawn by Sun Mo, it looked extremely beautiful.

One must know that Sun Mo wasn't simply a spirit runist, but he was also a famous artist. So, even simple lines like this would contain extraordinary charm if he drew them.

​​

"Does anyone recognize this?"

Sun Mo glanced at the corridor. "The people outside can answer if you know anything about this."

Sounds of whispers rang out as the students discussed fervently. However, no one knew the answer. In the end, all their eyes turned to Wanyan Mei.

In the Dragon Subduing Academy, she was publicly acknowledged as the best student in the study of spirit runes. Her standard was already near to a grandmaster.

"How is it?"

Sun Mo asked with a smile.

Wanyan Mei had a cold look on her face, but she felt extremely awkward in her heart to the point where she felt like dying. She proclaimed herself as a grandmaster spirit runist and looked down on many teachers teaching spirit runes. But now, she was stumped by an intern teacher.

(Preposterous.)

Wanyan Mei drew in a deep breath and stood up as she bowed. "I don't know. Teacher Sun, please provide us with your guidance."

"Sit down first!"

Sun Mo smiled. "You don't have to feel bad about yourself. It's very normal you don't know anything about it because this is a spirit rune I created."

"What? Another creation?"

Even students who didn't focus on the 'study of spirit runes' understood the concept of creation. Hence, let alone those who were watching Sun Mo's skill for the first time, even the students from yesterday were incomparably shocked now.

"Sir, how many spirit runes have you created?"

A student asked in shock.

If someone created one, it was enough for them to boast half their lifetime. They were qualified to enter the rank of grandmasters.

(Yet, you actually took out a few in just two lectures.)

"This is also known as the Rain Gathering Rune!"

As Sun Mo spoke, he activated the spirit rune.

Spirit qi gathered and very soon, they formed a black cloud in the air. After that, sizzling sounds rang out and rain began to fall.

"It's really the rain gathering rune."

Everyone exclaimed in shock

This spirit rune was usually used to water the fields.

In war or on an explorative expedition, one could use the rain gathering rune if they lacked water or needed it for an emergency. The rain gathering rune was commonly seen, but none of them had ever seen the rune Sun Mo drew before.

Wanyan Mei left her seat and walked to the platform. She dipped her hand into the rain water and then tasted it.

"Teacher, the amount of spirit qi contained in this rain seems to be very high."

A sense of defeat rose in Wanyan Mei's heart.

Sun Mo was only eight to nine years older than her. Yet, his expertise had reached such a realm…

Sigh!

No matter how confident Wanyan Mei was, she didn't feel she could create her own spirit runes ten years later.

"Yup, this is where the essence of my rain gathering rune lies. Not only can it increase spirit qi, but it can even reduce it. I can control the density of spirit qi in its rain."

Sun Mo's casual sentence created a huge commotion in the classroom.

"Impossible!"

Wanyan Mei subconsciously doubted.

"Why is it impossible?"

Sun Mo counter-asked.

"B...because…"

Wanyan Mei wanted to say that the difficulty of doing this was too high, but after she saw Sun Mo's eyes which were filled with confidence, she suddenly had no way to speak. What if Sun Mo was really that impressive?

"Everyone knows that because the aptitudes of cultivators are different, there might be some who suffer symptoms of spirit intoxication. Actually, the plants can have a similar reaction. The amount of spirit qi that they need is different according to their growth periods."

Sun Mo introduced, "This is none other than the reason why I created this particular rain gathering rune. It can allow plants to enjoy the most suitable amount of spirit qi during their different growth periods."

This sentence was very easy to understand.

Plants had their sapling stage and their mature stage. Hence, the amount of spirit qi needed would be different between them. But how did planters adjust such a thing?

They would simply water less!

This was because for normal rain gathering runes, once they were activated, no one could cancel their effects. Hence, planters would use all types of methods to not allow the qi-filled rain water to enter the field.

Such an operation was extremely troublesome.

But it was necessary. Because the more valuable a medical herb was, the more stringent its growth requirements would be. If not, even if it managed to mature, it would be considered an inferior product.

"From the development of the study of spirit runes up until now, the rain gathering rune that's passed down from ancient times is undoubtedly one of those with the highest cost-to-performance ratio. But it's impossible to use it in line with the local circumstances because the need for spirit qi is different for each plant. However, with my rain gathering rune, as long as you understand the theory, even a beginner can adjust the spirit qi in the rain water after modifying the spirit rune."

Sun Mo spoke frankly with assurance and grew excited. However, the face of everyone in the classroom and corridor was filled with dumbfounded looks.

Because this concept was too exaggerated.

"I thought only those at the rank of grandmaster spirit runists or higher can modify spirit runes?"

Someone didn't understand.

"You guys treat spirit runes as something too difficult."

Sun Mo's lips curled into a gentle smile, causing everyone to have a very good impression of him.

Many girls felt regret. If this teacher was more handsome by just a bit more, how good would it be?

"It's still that same old sentence. Spirit runes are actually a type of expression. You all can understand it as a type of content. Different spirit rune patterns are like a language elaborating on expressing different content."

Sun Mo deliberated his words before speaking.

"Let's put it this way. The various tribes of the great plains have so many ways to express their thanks. But is it difficult to understand their intent?"

"No!"

"If you scold someone, you don't even need to say any words. A single gesture would be able to communicate your intent."

"Hey, we are having a lesson right now, can you guys be more serious?"

Sun Mo lightened the atmosphere with some examples.

The students giggled. They were pretty fond of Sun Mo's class. It was relaxed, not solemn at all and was different from those pedantic old fellows who would scold you the moment your sitting posture was the slightest bit not upright.

"For a language, it would only be recognized if it was promoted and many people started using it. If not, you would be treated as a mental case talking to yourself. However, there's no need to do this for spirit runes. Because even if you are the only one that understands their intent, it can also be activated."

Sun Mo rapped the black board. "The spirit runes we are learning are only circulated around because many people are using them."

"Teacher Sun, you mean I can also create a unique spirit rune belonging to me?"

Wanyan Mei asked in shock.

"That's right."

Sun Mo nodded with certainty.

"In that case, what do I have to do?"

Wanyan Mei was impatient.

"Don't be anxious. I will gradually elaborate on this in my future classes."

Sun Mo mentally mused. (If I reveal everything in one lesson, what can I depend on to attract popularity in the future?)

"Che. Teacher, you are so cunning!"

Many people made booing sounds, but they were all made in jest.

Wanyan Mei gritted her little white teeth and wanted nothing more than to grab Sun Mo by the neck and force him to spit out the answer.

This feeling of waiting was simply too tormenting.

"Teacher, earlier you said before you wanted to reveal a spirit rune that's a unique creation. Are you referring to this?"

A female student asked.

"The rain gathering rune, in addition to those impractical but similar ones, consists of slightly over ten variations. So it's not it. Since I spoke about creation, I naturally meant a unique creation."

After Sun Mo spoke, the entire classroom directly fell silent.

It was only after ten seconds did a great teacher speak out.

"Teacher Sun, are you saying that you created a unique creation, something that doesn't exist currently in our spirit rune world?"

"That's right!"

Sun Mo spoke the two words lightly, but their weight was so heavy that it caused the several hundred students here to inhale a breath of cold air.

(T...this Teacher Sun...c...could it be that he's already a great ancestor?)

One must know that the standard to determine a great ancestor-level spirit runist was whether they could create a unique spirit rune never seen before in the Nine Provinces.

Sun Mo also no longer spoke nonsense. He pasted a piece of spirit rune paper on the blackboard and began to draw.

The entire classroom had been extremely noisy due to shock. But as Sun Mo took up the brush, all other noises immediately vanished.

In fact, some students didn't even dare to breathe loudly. They were deeply afraid they might disturb Sun Mo and caused the drawing of the spirit rune to screw up.

"In order to let everyone see clearly, I will draw slower."

Sun Mo appeared like he was thinking of the students, but in reality, he didn't want to screw up. After all, after he modified this spirit rune, he didn't draw it often.

Sun Mo's current aim was to make a spirit qi tornado appear after drawing it. By doing so, he would be able to give everyone an image that he was a grandmaster.

Only after 20 minutes later was the spirit rune completed.

Sun Mo's cautiousness and meticulousness also had some merit. A spirit qi tornado brewed and drew all the spirit qi in the classroom over.

"Although I don't know what spirit rune Teacher Sun is drawing, just looking at the diagram is enough to fill my heart with joy."

"It feels like a famous painting!"

"Have you seen a famous painting before?"

When he heard the sounds of discussion from the students, Sun Mo really wanted to say. (You guys have never seen a famous painting before?)

(It's fine, I will draw one for you guys to see!)

(But forget it, I probably should wait longer before acting cool in the future.)

"Princess, do you understand?"

A son of a minor tribal head asked because he was more familiar with Wanyan Mei.

Swish~

Wanyan Mei immediately turned over and glared at the person with a furious look in her eyes.

(What? Are you mocking this princess? He has already said it is a unique spirit rune, so who in the world would be able to recognize it?)

Naturally, Wanyan Mei was unhappy mainly because her thinking got interrupted. She wanted to depend on her own capabilities to decipher this spirit rune.

Sun Mo swept his gaze around the crowd and so coincidentally saw Beardie standing in the corridor. Hence, he decided to greet Beardie.

"What a coincidence, can I trouble you to block the effects of this spirit rune?"

At this moment, if Beardie rejected this, his popularity would definitely decline sharply. Everyone would feel that he was afraid. Hence, he had no choice but to walk out.

"You have to be careful. The destructive might of this spirit rune is very great."

Sun Mo reminded him. "You better have a weapon in your hand!"

Beardie had wanted to take his weapon out, but after hearing these words, arrogance surged in his heart and he actually decided to do this bare-handed.

(Hehe, silly fool.)

Sun Mo had provoked him intentionally. The attitude of this Beardie wasn't good, so Sun Mo had long since wanted to teach him a lesson.

"Are you prepared?"

Sun Mo asked.

"Bring it on!"

Beardie revealed a casual attitude.

Sun Mo tore the spirit rune. Crackle!

It felt like two flints had ground against each other in the air. A spark erupted forth and rapidly ignited, transforming into a coconut-sized fireball. After that, it shot out with a swoosh.

"F***!"

Beardie was shocked. The speed of the fireball was too quick. In the blink of an eye, it had appeared before him. The fiery temperature roasted his hand and caused him to feel pain.

His instinct was to evade it, but there were still students behind him. Hence, he could only grit his teeth and bear the impact forcefully.
