After returning to the villa, the three of them stopped for two days.

Linlu and Jiujiu were addicted to the practice of small cakes, and they worked tirelessly in the kitchen every day to experiment, although the scene was a little tragic, but they finally didn't blow up the kitchen, which made Su Xiao a little relieved.

As for Su Xiao himself, he was studying his sudden increase in fire resistance. While practicing the power of control every day, burn yourself with fire by the way.

But it was not as good as that day's effect, although it was indeed a lot better than before, but no matter how small the flame was, it could not achieve the effect of almost flame immunity that day.

This gave Su Xiao a strange thought in her heart.

Qiyue was at the scene that day, and she was the one who controlled the flames, so she was not injured.

Of course, this is also Su Xiao's self-inflicted sentimental idea, without any basis, but it seems to be true, always thinking so in his heart.

Until, Chu Yuan pried open his door.

Seeing Chu Yuan who appeared at his door, Su Xiao was stunned for a moment, and then hit the fire spirit fish over.

It's also scary to see ghosts in broad daylight.,Especially a male ghost who doesn't have a good temper.。

Chu Yuan also didn't expect Su Xiao to be so "decisive", and subconsciously took a step back, and the fireball hit the linlu behind him, the doughnut in his hand.

Looking at the doughnut that turned into char in his hand, Linlu, who was originally talking and laughing, was stunned for a moment, with a black face and a look of wanting to kill.

If Chu Yuan wasn't there, I'm afraid it wouldn't just be the door frame that would be crushed at this moment.

Looking at the precarious wall, Su Xiao decisively took Chu Yuan's hand and said with an amiable smile: "This is not the one who ...... Classmate Chu! ”

For a guy like Chu Yuan, who has only met once, whose name is complicated in Pan-continental language, Su Xiao has always only remembered his person, not his name.

Although I don't know how he got in alive, since he was followed by Linlu, he wasn't a bad guy in comparison.

Thinking of this, Su Xiao couldn't help but shudder, and cautiously glanced at Linlu.

At that moment, he had the feeling of looking at the abyss.

What could be more terrifying than an angry deer?

Thinking of this, Su Xiao had a hypocritical smile on his face and gently closed the door.

Then he breathed a sigh of relief and sat down on the ground.

"Tell me, what did you come to me for?"

Looking at Su Xiao's lazy look, Chu Yuan's face was a little strange, but he seemed to have thought of something, and respectfully bowed to Su Xiao, making Su Xiao a little confused.

"Although Brother Su is from a humble background, he is neither humble nor arrogant, and it is really worth learning from me with an open mind......"

"Speak well."

"I want to know, the secret of your flames."

Hearing Chu Yuan's intention, Su Xiao subconsciously contracted his muscles, and Yuan Ling almost rushed out of his body.

Fortunately, after the last transformation, Su Xiao's ability to control has also become much stronger, which can suppress his instinctive killing intent.

Xingyuan's secret is really too involved, and once the fact that Xingyuan is hidden in himself and Jiujiu is exposed, the consequences are unimaginable.

But after thinking about it, if it was really Xingyuan's matter that was exposed, then it couldn't be Chu Yuan, a B-level student, who was visiting.

Thinking of this, Su Xiao breathed a sigh of relief and tried to explain his nervousness just now, but before he could speak, Chu Yuan held Su Xiao's hand and said affectionately:

"You definitely don't want this kind of secret to be leaked, I know, but I really need your technology to help me complete the sublimation of the Yuan Spirit."

Su Xiao was confused when she heard this, and asked suspiciously, "What technology?" What sublimation? And what are you talking about confidentiality? ”

Seeing Su Xiao trying to pretend to be stupid, Chu Yuan took out a thick notebook and said solemnly:

"I'm not going around in circles, I'm here to teach me the explosive power of the flames. That is, the power you use to defeat me. ”

"Don't say it's the power of your primordial spirit." Chu Yuan confidently opened the thick notebook in his hand, and said proudly:

"I've checked, your Yuan Spirit belongs to the Fire Domain Realm of the Burning Plains Family, and your name is not in the genealogy of the Li family, a branch of their family in the Holy Capital. That is to say......"

Hearing this, Su Xiao also became nervous, thinking about how to kill people for a while. However, before he could figure out what to do with the remains, Chu Yuan once again held his hand affectionately and said in a low voice:

"That is, you are the bastard of the Burner! Despite being neglected and uncared for since childhood, you have developed this new primordial spirit technique with your own efforts, which is a great miracle that even the Burner himself has not been able to do! ”

Looking at Chu Yuan's excited face, Su Xiao covered his face with a headache.

What he said was extremely emotional, his tone was sincere, and his emotions were sincere, containing his strong respect for Su Xiao, and Su Xiao was almost taken seriously.

"So, classmate Su Xiao, give me your spell full of explosive power and destructive power!"

Looking at Chu Yuan's sincere face, Su Xiao looked out the window helplessly, and after confirming that there was no law enforcement team from the temple outside, he sighed, and the flame in his hand slowly rose.

"Now, let's talk about the conditions."

"Conditions?" Chu Yuan's face was embarrassed when he heard this, "I don't have this level of secret art to exchange, what do you want?" ”

"Let's talk about your purpose first." Su Xiao looked a little helpless. After all, he still hadn't figured out what Chu Yuan wanted to do with the power of extinction.

"I want to use this power to forge a new Yuan Spirit weapon, so that my Yuan Spirit can improve the level of a quasi-Yuan Spirit and obtain the admission qualification of a student in the Black Iron City."

"The City of Black Iron?" Su Xiao frowned, as if recalling the specific meaning of the term.

"It's the city-state located in the northern part of the Holy Capital, sending cadets to the front line all day long to fight and hone against the army of the Temple?"

"Yes! That's the holy place where we and other instruments are primordial spirits! ”

"Equipment?" Su Xiao glanced at Chu Yuan suspiciously, "Is there such a category in the regular Yuan Spirit classification?" ”

"Strictly speaking, his correct title should be the Department of Mechanics, not the old-fashioned and primitive traditional machinery, but the perfect integration of Yuan Ling and mechanics ......"

"Stop!" Before Chu Yuan began to explain the origin of the mechanical department, Su Xiao interrupted him decisively and said with a serious face:

"I'm not interested in the mechanical department, and I guess it won't have anything to do with that black iron city in the future, so you skip this part and talk directly about your promotion."

"Okay." Chu Yuan looked a little lost, but then returned to normal.

"My promotion method is different from most people, and I need to constantly smelt the Yuan Spirit weapon to improve my Yuan Spirit realm."
