() Although Skyfire may seem very arrogant, it is undeniable that there is something about her research on the source stone.

The amount of knowledge collected in this class is almost equivalent to a large part of the formal course, and her explanations are simple and easy to understand, and much of the knowledge is not found in the textbook.

Other teachers only dare to use guessing in class to explain carefully, but she dares to explain in an affirmative tone, which promotes students' understanding and recognition.

The whole class was silent, everyone listened attentively, and even Xia Feng, a scumbag, took notes seriously.

According to the type of natural disaster and geology, it is not too useful to speculate on the growth law of the source stone.

.....

After speaking for more than 1 hour in one breath, Tianhuo put down the whip.

"Probably several geology and corresponding laws are these, and there are some relatively rare cases, because of the time relationship, I won't explain it here, do you still have any questions that you don't understand?"

In the face of Tianhuo's powerful aura, none of the students below dared to ask questions out loud, Tianhuo spoke in great detail, and they were afraid that their idiotic questions would be embarrassed.

At this time, Xia Feng raised his hand.

"I have a question for you."

Skyfire looked at Xia Feng, who was sitting in the last row.

"Excuse me."

Xia Feng quickly sorted out his thoughts and asked calmly.

"Teacher Tianhuo, I want to ask, what is the probability of ordinary people contracting ore disease by using the source stone release source stone technique, and is there any accurate research data?"

Xia Feng's question made all the students in the class stupid.

Ordinary people want to use the source stone to release the source stone technique, but they are afraid that their heads will not be kicked by a donkey, which is like asking a panda how long it can hold its breath if it wants to dive in the deep sea.

Let's not talk about whether it can cause disease or not, but in advance is the source stone technique that you need to be able to release.

However, Tianhuo did not frown at this abrupt question, and she replied seriously.

"Don't call me teacher, I'm a student like you, as for this question, there is no accurate data at present, but I personally believe that if the caster uses a natural source stone bush, the chance of disease will increase exponentially with the frequency of use."

Xia Feng continued to ask.

"And what if it's a finished source stone?"

"The finished source stone needs a special method to use, some people only know how to release the source stone skills, but do not know how to consume the source stone, which will make a small amount of residual source stone substances in the body, although the pathogenic rate of the finished source stone is very small, but over time, there is still a risk of disease."

Xia Feng nodded thoughtfully.

"I see."

Skyfire continued.

"Of course, this is to distinguish the type of source stone skills, some auxiliary source stone skills can be released with the help of simple tools, which will greatly reduce the risk, but if it is a means of mass destruction warfare, you need to pay extra attention, even if it is an infected person, if it is done in the wrong way, it will increase the degree of infection."

Xia Feng pursed his lips.

"Senior Sister Tianhuo, do you know the correct way to release the Source Stone Technique, and how to avoid the risk of disease to the greatest extent?"

"Of course I know this, but it's very complicated, it's not a few words, a few lectures can explain it clearly, because different individuals, everyone has different understandings and skills, and my skills may not apply to everyone."

Ordinary people can avoid the chance of causing illness by releasing the Source Stone technique, which almost subverts the three views of the students in this classroom.

But Xia Feng knew that what Tianhuo said was true, because she herself was the best proof of it.

Skyfire is a powerful Source Stone Sorcerer, and her Source Stone spells possess the power of mass destruction to destroy the world.

But at the same time, she herself is an uninfected.

......

After class, Xia Feng immediately stood up, wanting to talk to Tianhuo about the source stone technique in detail, if he could, he wanted to make an appointment with Tianhuo.

But unfortunately, there are many students who think the same way as him, and as for Tianhuo himself, he runs faster than a rabbit like an idol at the end of the concert.

Paddy walked up behind Xia Feng and patted him on the shoulder.

"Xia Feng, you'd better not approach Senior Sister Tianhuo, I told you before that she is a member of the King's Staff, and my cousin told me about this, and he won't lie to me."

Xia Feng sighed.

"If you want to get close, then you have to be able to find talent, forget it, let's go to dinner."

....

Midday.

Paddy wants to go to the big canteen again, but at Xia Feng's insistent request, Paddy can only go to the Royal No. 1 Restaurant with him.

After entering the restaurant, Xia Feng casually pointed to an empty seat.

"You go sit first, don't run around, you can eat whatever you want, I'll have a treat today."

At this time, it was just noon, and there were not many students in the cafeteria, and the waiter instinctively became vigilant after seeing the summer breeze.

A neatly dressed waiter bowed slightly.

"That.... Master, you're here again. ”

Xia Feng waved his hand.

"I'm not a young master, or I'm a poor student, but I can afford to eat."

"Then you ....."

"Don't worry, I'm here to eat this time, I won't cause trouble, and you don't have to keep staring at me."

The waiter smiled awkwardly.

"No, no, the customer is God, how dare we stare at you."

....

Leaving the waiter, Xia Feng went to the buffet area to pick up an apple, and strolled around the restaurant while biting it.

Soon, the person he was looking for appeared.

In the corner of the dining room, Karn and his sister, Miss Two, sat on one side of the dining room, while on the other sat an old familiar friend, Ricky.

At this time, there was only one bottle of wine and two plates of salad on the table, and it seemed that they had just arrived.

Xia Feng quietly approached the wall and secretly forced behind Lieqi, and then, he took a deep breath.

Ricky didn't notice the people behind him, including Karn, who didn't notice the students walking around the cafeteria.

Ricky put down his glass, took a fork and picked up a small tomato on his plate, ready to put it in his mouth to taste.

At this moment, Xia Feng jumped out from behind him and shouted.

“surprise！”

The sudden shock almost scared Richie's heart attack out, the fork fell off the table, and the little tomato gurgled out of the way.

Lie Qi clutched his heart and stared at Xia Feng in horror.

"You..... You...."

Xia Feng smiled cheaply.

"Hehe, it's me, I just came back yesterday, and today I met Ricky-classmate, it's really fateful, it just so happens that Young Master Karn is also here, so I'm welcome."

After that, Xia Feng sat directly and generously next to Lie Qi.

Karn's face on the other side was very embarrassed, and the second lady gently tugged at the corner of Cain's clothes, as if she wanted to signal him to leave quickly.

Karn's face darkened.

"You....... Why are you here again. ”

Xia Feng estimated that what Karn really wanted to say was "how are you still alive", but he changed his words temporarily.

Xia Feng took an empty cup and picked up the wine by himself.

"Oh, people are iron rice is just, always have to be just right, it just so happens that I want to find the two of you today, the little brother is welcome, I'll do it first as respect."

After that, Xia Feng directly drank a full glass of red wine with his head up.

Putting down the wine glass, Xia Feng sighed deeply, looking like an enlightened person who had comprehended the true meaning of life.

"I'll tell you the truth, brother, I have figured it out recently, I am neither a nobleman nor a rich man, there is no need to charge a big head of garlic, my arms can never twist my thighs, I only have one life, I want to be a good person."

Karn was bewildered by Xia Feng's inexplicable confession.

"What do you mean by that?"

Xia Feng filled the wine again and sniffed.

"Master Karn, there have been many offends in the previous incidents, you don't care about the villain, just let me go."

Karn and Second Miss looked at each other.

"This ....."

Xia Feng sighed again.

"Sure enough, you still don't want to forgive me, otherwise let's do it, when the food is served, you pick a plate that you don't like to eat, and directly deduct it on my head, even if I make amends to you."

This time it was Karn's turn to be embarrassed, his face was cloudy, but from Xia Feng's sincere tone, he only heard one word, cowardice.

"Are you scared? Wasn't it quite arrogant before, it's not like you. ”

Xia Feng pursed his lips.

"People will change, especially after experiencing the threat of life and death, they will become even more afraid of death."

With that, Xia Feng looked at Lie Qi next to him again.

"Classmate Lieqi, I received your gift, but Xia really can't afford it, I won't dare to participate in the affairs between you big people in the future, you raise your noble hand, just treat me as if I am dead."

...

Subsequently, Xia Feng's whole voice burst into tears, and the corners of the eyes of the second lady were moistened by the sincere words.

The second lady pulled the corner of Lakahn's coat.

"Brother, if you don't have to worry about Xia Feng, it's not easy for everyone."

Karn was also helpless, he was a little convinced that Xia Feng was really scared, and sighed.

"Okay, but I have a request, find a time, you have to formally apologize to me in front of the students, and let all the students know your attitude."

Xia Feng wiped a handful of snot.

"No problem, you can do what you say, or you can set up a stage and do a live broadcast, and I will kowtow to you in person and admit my mistakes."

Karn waved his hand.

"That's not necessary, let's talk about this later, I'll send someone to find you."

“ok。”

Xia Feng looked at Lie Qi again.

"Young Master Lieqi, look at this matter......"

Xia Feng had already made his words clear, he knew that it was Lieqi who wanted to kill him, but his attitude was not revenge, but confession.

It stands to reason that since it comes to this point, there is no need for Lieqi to kill them all, but there is one thing that Lieqi can't figure out.

That is, why didn't any of the killers he sent out before come back, if he hadn't seen Xia Feng today, he would have thought Xia Feng was dead.

But it had come to this, and he couldn't say anything in Karn's presence.

"Forget it, this matter is over, as long as you and the chairman of Karan Trade disassociate themselves, we will not interfere with the river water in the future."

Xia Feng's tone was firm.

"Young Master Lieqi, don't worry, in the future, that old boy in Silver Ash, I will dare to pit me when I see him fight again."

.....

After a few more glasses of wine, Xia Feng got up respectfully and said goodbye.

After a big circle, he returned to Paddy's table at the door.

Seeing that Xia Feng had been back for so long, Paddy asked as he sipped his drink.

"Xia Feng, why did you go?"

Xia Feng sat across from him lightly.

"It's nothing, go and have a memorial service for someone, by the way, what did you order?"
