Su Su whispered, "This is the Fire Crystal that was lost earlier? How did you get it?"
Xiang Nan said, "Let's not talk about this. Do you know where there are artifact forging masters here?"
What Xiang Nan had learned was a very brilliant tool forging technique, but even though the Profound Grade tool forging technique was very brilliant, it only recorded the techniques of tool forging. However, it did not make a clear analysis of all the tool forging materials in the world.
Xiang Nan still didn't know what the fire crystal was used for, so he had to investigate this matter clearly.
"Oh." Susu turned around and pointed, "There is a master artificer from the Southern Domain in Exhibition Area 2 and VIP Room 13. You can go take a look."
"Do you want me to accompany you?"
"No need, your goal is too obvious." Xiang Nan shook his head and quickly walked towards the second exhibition area.
"My goal is too obvious?" Su Su frowned, a little confused by Xiang Nan's words.
Exhibition area two, VIP private room area, single room thirteen.
A gray-bearded old man was sitting on a soft wool carpet with a beautiful maid in his arms.
This old fellow's forging attainments were average, but he knew a lot. He was a forging master of that kind of theoretical school, and his real ability to make a move was limited because of his innate talent.
The door was pushed open and Xiang Nan strode in.
The old man frowned, "Who let you in!"
Xiang Nan raised his right hand and a flame condensed into a beautiful phoenix in the air above his palm. The phoenix was carved vividly, and even every feather was incomparably clear.
"Cosmos Fire Control Technique!" The old man's expression became serious as he shouted, "Both of you, get out! Let me talk to this little brother."
The two maids were already disgusted. However, their identities were limited. They had to accompany this perverted old fellow here. When they heard that they could leave, they naturally ran away happily.
"You're half a gourd!" The old man's expression softened and he smiled at Xiang Nan.
Xiang Nan used the Cosmos Fire Technique from the start. He knew that half a gourd was the number one expert in the pill refining and artifact forging world of the Southern Domain. All the experts of the Profound Dao of the Southern Domain worshipped half a gourd.
"I'm his disciple." Xiang Nan placed the fire crystal on the table. "Excuse me, what's the use of this thing?"
The old man said, "Five-pronged fire crystals are useless. They are just good-looking."
It didn't work? I shouldn't.
Xiang Nan frowned and said, "Then may I ask Senior, if this item is related to the key and lock, what can you associate with these two keywords?"
The old man's expression quickly changed, but he lowered his head and pretended to drink, hiding the change in expression and said, "Nothing, I can't think of anything."
Xiang Nan noticed the changes in the old man's details. He slapped the table and shouted, "Do you still want to stay in the Southern Domain? Let me tell you, if you don't tell me the truth, I'll go back and report it to my master truthfully. I'll take care of you for the rest of your life, and you won't have a foothold in the Southern Domain!"
The old man trembled in fear and hurriedly said, "No, no, no, alas, I said you mustn't tell anyone."
"You're here for the Seven Qiaoqiao Lock, aren't you?"
Xiang Nan's eyes lit up and he immediately nodded.
The old man said, "A few days ago, a very terrifying woman found me. You know, facing her, I have to say anything! If I don't say anything, then I really can't survive, I can't beg for death …"
"Ghost Doctor." Xiang Nan blurted out.
The old man was stunned for a moment. "You even know about this? It seems like you really have some information. Little friend, please don't find half a senior gourd to report me. We old fellows all rely on him to have our current status. If …"
"Cut the crap!" Xiang Nan stared blankly and said, "Speak directly! What does the fire crystal have to do with the Seven Skills Mother and Child Lock?"
The old man coughed dryly twice and said, "If you ask someone else, I'm afraid nine out of ten artificer masters won't be able to answer, but I know."
"This Seven Skills Mother Lock is a very exquisite item, and the greatest use of fire crystals is that it is a kind of soft metal that can change its shape at will."
"If you melt the fire crystal and put the liquid into the keyhole, it will change shape continuously with the shape of the Qi Qiao Lock. Even after the fire crystal cools down, it will still be able to change continuously."
"In other words, this fire crystal can become another complete key?" Xiang Nan suddenly understood.
The old man nodded, "Yes, but fire crystals are not enough. The Seven Skills Mother and Child Lock is not only named because of its shape change, but also because of its importance."
"This kind of Seven Skills Lock can sense the fluctuations of life force in one direction."
"Let's put it this way."
The old man placed seven teacups on the table and said, "If you take the key made of fire crystals, open the treasury door and enter."
"At this time, the treasury will automatically lock you in. Your keys will also be null and void. No matter what means you have, you will not be able to escape."
"There must be seven key holders standing outside the door to open the door for the people inside."
"Therefore, the person who transports the treasure into the treasury every time cannot be the person who controls the key."
Xiang Nan was puzzled again. There was a key to enter, but he couldn't get out?
After a long time, the Seven Skills Lock had two different ways to open the door. There were living things in the treasury, and the way to open the door was different from when there was no living thing.
When there was no life form, one could use a key to open it. When there was a life form, one had to use seven keys to control the fluctuations of one's life force to open it.
Unless the people of the First Grade Hall were able to subdue Gang Lie, even if they could enter, they would still be released from the door.
Since that's the case, why would the people of the First Grade Hall steal fire crystals?
"Does the Ghost Doctor know about this?" Xiang Nan asked.
The old man hurriedly nodded, "I know, I told her."
"You bastard." Xiang Nan glared at the old man and said, "Don't tell anyone about what I asked you. Otherwise, I'll take your life!"
With that, Xiang Nan turned around and went out.
When Xiang Nan had just left, the old man heaved a sigh of relief and said, "Are you satisfied now?"
In a corner, on a sofa, air suddenly shook.
Immediately after, a transparent cloak was lifted. Behind the cloak, sat Guan Xiao and her teammate, the delicate and handsome man.
The handsome man shook the wine glass in his hand and smiled, "You really expected it, but this brat still came."
Guan Xiao took a sip of wine and said, "He thought he could secretly control everything. Haha, very cute person."
"Alright." Guan Xiao walked over and patted the old man's shoulder, "You did well, I can spare your life."
The old man panicked and said, "But, what I told him was the truth. Why did you reveal this to him?"
"That's none of your business." Guan Xiao shook her head, "Live your life well."
"Yes, yes." The old man hurriedly nodded.
Guan Xiao waved to the handsome man and said, "Go, continue with the mission."
The handsome man smiled. He put on a transparent cloak and disappeared again.
Guan Xiao came to the corridor outside and looked at Xiang Nan in the crowd in the distance. She muttered to herself, "I always feel that this person is very familiar, but I don't know who he is."
"It's really strange."
Guan Xiao had doubted Xiang Nan more than once, but she just couldn't connect Xiang Nan with the great hero of the Southern Domain, Xiang Nan.
She doesn't believe that a person can come back from the dead.
Even if it seemed to be the most likely thing to happen, as long as he reasonably deduced the cause and effect, he had to respect the truth!
Xiang Nan's body had already exploded, and he would definitely not survive.
