Finally, the exciting moment came, the legendary and fantastic spirit martial arts were finally about to surface, thinking of this, Eisen's heart was excited, and the excitement followed closely behind Griffin.

After a while, Griffin took Eisen to the research department within the Forge Chamber Association, and came to a huge elevator, which was somewhat similar to the elevators on Earth, but more magical than the elevators.

"Because the spirit of the machine spirit is extremely valuable, just in case, we decided to store it in the most heavily guarded underground storage vault in the Research Department," Griffin explained as he activated the elevator.

"Underground storage?" Hearing this unfamiliar term, Aisen was a little puzzled.

"The underground vault is where some of the most precious magic artifacts and some extremely rare materials are stored," Griffin patiently explained in the elevator.

"Of course, because it's an important place, the garrison here is much tighter than outside......

After a clang, the elevator landed steadily on the ground, and with the opening of the automatic door, Aisen looked at the space in front of him with some surprise.

Different from the dimness of the underground in Eisen's imagination, bright lights fill the entire space, and the soft light gives people a comfortable feeling, and the dreamy architecture makes people feel like a dream.

At this moment, several powerful breaths suddenly came from the depths of the corridor, and then with the roaring sound of armor, a neat army appeared in front of the two of them.

The leader of the army was a heroic man wearing white heavy armor and a giant sword at his waist, and the aura on the man's body was extremely powerful, and later, Aisen knew through the detection system that the man at the head of the army was actually a paladin! Even the worst of the other members of the army had the strength of a silver knight.

Looking closely, Aisen found that there were several magicians at the end of the line, and the advancement of this magician had reached the level of a high-level magician!

"Elder, please show me proof of authority!" said the man at the head of the team as he walked up to Griffin, holding his head high and solemnly.

After a while, Griffin took out a small and delicate badge with a strange aura from the spatial ring and handed it to the paladin at the head.

The paladin respectfully accepted the medal, looked at it carefully for a long time, and finally handed it back to Griffin, saying, "No problem, President Griffin, you can enter"

The paladins then dismissed their troops and disappeared into the corridors.

Aisen looked at this orderly, orderly and powerful team with some astonishment, and couldn't help but marvel at how tightly guarded this underground storage vault was.

"Alright, Eisen, let's go, Tsuruko is probably in a hurry" Then, Griffin took Eisen and walked deeper into the corridor.

Along the way, this underground storage vault was an eye-opener for Aisen, and in the crystal cabinets next to the corridor, none of them were placed with extremely precious magic guides, and any random one would attract fierce competition from the outside world, and for a while, Aisen was also surprised by the profound heritage of the Forge Association.

Finally, the two of them came to the end of the corridor, and a bronze door appeared in front of them, and behind the door was stored the spirit martial arts that Aisen had been thinking about day and night.

Then, Eisen followed Griffin into the bronze gate with great anticipation, and suddenly an illusory figure suddenly appeared in front of Eisen, startling him a lot, and after calming down, he found that this illusory figure was Qinyun Crane.

"Aisen, you're finally here! Live up to expectations, Xiao Fenfen and I have successfully forged Lingwu, and this is also the most successful forging we have ever had! You will definitely like her, don't be frightened by her charming" Qin Yunhezi shouted excitedly.

But this excitement could not hide the haggard on her face, and the thick dark circles on her eyes, as if she had not fallen asleep for several days.

"Hey, Aisen, don't you know, since Tsuru got the Flame Spirit Stone from you, the whole person is like taking stimulants, sleepless day and night, guarding the front of the forging table every day" Griffin looked at the excited Qin Yun Crane, and sighed a little distressed and helpless.

"Thank you very much!" said Tsuruko-sensei," Aisen said gratefully.

"Leave that alone, come and see this Lingwu, you'll love it!" Qin Yun Tsuruko didn't care about Aisen's thanks, but grabbed Aisen's wrist and brought him to a delicate sword box.

Seeing the delicate sword box in front of him, Aisen couldn't help but swallow his saliva, and with some nervousness, he touched his hand to the smooth surface of the sword box like jade, and slowly opened the sword box like opening a treasure.

At the moment when the sword box opened, a bright red blood-colored light suddenly shone out of the sword box, filling the entire space, and everything was covered with a layer of evil aura by this bewitching red light.

Under this bewitching bright red light, Aisen finally saw the sword lying quietly in it.

The bewitching bright red is the main color of the sword, and the delicate hilt sets off the crystal transparent sword body, at this moment, Aisen can't describe the beauty of this sword in words, the only thing that comes to mind is the word bewitching.

"It's... It's my Lingwu ......," Aisen sighed in disbelief.

"That's right, only by forging it with your own hands can you deeply appreciate the horror of the elemental spirit stone, the appearance of this sword is transformed by itself, not so much that we created it, not that the elemental spirit stone created this sword, we are just a tool to link the two" Qin Yunhezi was a little excited, and said excitedly.

Or because he was too emotional, Qin Yunhe shook a few steps in a bit of distraction, as if he would fall down at any time.

Seeing this, Griffin hurriedly took it in his arms, and said distressedly, "I said don't let you work so hard, why don't you listen?"

"It's okay, I just haven't slept for a few days and I'm a little weak," Qin Yun Tsuruko responded with a gentle smile and said softly.

"By dropping blood on the sword body of this Lingwu, you can establish a connection with it, but this does not make you control it, and only by making a contract with the spirit in the sword can you fully control Lingwu and become her sword master, but...... It is extremely dangerous and difficult to become the sword master of the machine spirit, you have to be mentally prepared" Qin Yunhezi's face froze, and he looked at Aisen cautiously and said.

"I see," Eisen nodded earnestly.

Immediately after, under the guidance of Qin Yun Tsuruko, Aisen dripped his blood on the sword body, and suddenly there was a buzzing sound from the bright red sword body, which vibrated slightly, but after a while, the vibration stopped.

"Is this the connection?" muttered Eisen

"Okay, now that this sword has established a connection with you, let's give her a name, after all, this is a sword born because of you" Qin Yunhezi smiled weakly and said softly.

"Name, this sword was born from the Flame Spirit Stone, and it is as beautiful as a ghost, so let's call her the Charm Flame" Aisen thought about it and smiled.

"Flame Spirit Demon Queen, Charm Flame, this name is not bad" Qin Yunhezi repeated the name as if fascinated, and finally praised it endlessly.

"Teacher Hezi, I don't know how to fully control this Lingwu and become her sword master" Aisen looked at the bewitching long sword lying quietly in the sword box with some obsession, and respectfully asked Qin Yun Hezi for advice.

In response to Aisen's question, Qin Yunhezi did not answer immediately, but paused with some hesitation, as if hesitating whether to tell Aisen about it.

Seeing Qin Yunhezi's hesitant appearance, Griffin gently squeezed her soft slender hand, and said with a smile, "Don't hide this kid, with this kid's character, even ten cows can't pull back his mind."

"Okay, but first I want to explain to you that it is dangerous to conclude a contract with the machine spirit, and from ancient times to the present, there are many people who have become invalids due to the failure of the contract, and have been lying in bed all their lives, like walking corpses" Under Griffin's persuasion, Qin Yunhezi finally let go of the worries in her heart and said to Eisen seriously.

"I see, Tsuruko-sensei, tell me how to conclude a contract with the machine spirit," Aisen said firmly without the slightest hesitation.

"Hey, sure enough, you kid is as stubborn as Xiao Fenfen said, I'll tell you," Qin Yunhezi sighed leisurely.

"After you establish a link with Lingwu, you can use your spiritual power to make your mind enter Lingwu's machine spirit space, find the machine spirit that belongs to the sword in this machine spirit space, pass her test, get her approval, and you can conclude a contract with it" Finally, Qin Yun Hezi told Aisen how to conclude a contract.
