Fang Han accepted the yellow talisman, and the tall and thin man immediately began to pinch the magic formula, and then shot out a spiritual light and landed on the teleportation magic circle at his feet.

Immediately afterward, the runes were engraved on the circle, and it began to shine continuously.

As the brilliance flickered, a white light flashed in front of Fang Han's eyes, and then there was a whirlwind of the sky, and the surrounding scenery began to blur.

A moment later, a flash of light flashed, and the others came to an unfamiliar hall, with the same magic circle under their feet as before.

He looked at the empty hall and realized that it was very strange that he was in the hall now.

The surrounding bluestone walls are inlaid with pale white crystals, and under the reflection of the crystals, a thin layer of white sand appears on the ground.

There was a long passage in the corner of the hall, and Fang Han saw that the hall was empty, so he just looked at it a few times and then walked towards the inside of the passage.

The passage was not long, and after a dozen steps, a slightly larger room appeared at the end of the passage.

In addition to the long table in the room, there was also a short, thin old man standing at the table and watching him.

You don't have to think about it to know that the old man should be the person in charge of the underground fire room.

"Boy, do you have the transmission note from above?" The old man said.

"It's nature."

Fang Han took out his hand, and the tall and thin man gave him the talisman just now.

The old man made a move, and the yellow talisman took off his hand and flew into the old man's boring big hands.

"High-level ground fire chamber, come with me." After listening to the information in the transmission note, the old man said to Fang Han.

Fang Han followed the old man through the hall aisle and came to the entrances of the two passages, on which were written a Dan and a device.

He and the old man walked in the passage, which was engraved with the words of the instrument, and walked to the end of the passage, and came to a closed stone door.

"Hurry!"

The old man pinched out a magic trick, and a finger of spiritual light fell on the stone door, and the stone door opened on its own, revealing a fiery red passage behind the door.

The old man led Fang Han through the fiery red passage and came to an empty hall, where there were many silver-white doors of the same size around the hall.

Fang Han looked at the many silver-white stone doors in the hall, the old man came to a stone door by himself, took out a white jade plaque and pasted it on the door.

The white stone door was stimulated by the jade plaque and opened automatically, and then the old man walked into the stone house with Fang Han.

The area of this house is average, only seven or eight zhang in size, and I don't know what kind of stone is used on the four walls, which looks very beautiful.

In the middle of the room, a large smelting furnace was placed, and there was a small hole under the furnace to attract the fire underground.

"The method of adjusting the size and height of the flame is engraved on that wall, and you can look at it for yourself."

The old man pointed to the wall with his hand, and handed the jade plate in his hand to Fang Han, "You take the jade card, as long as the door is closed, it will be cut off from the outside world, and if you want to open the door and enter and exit, you must use the jade talisman to stimulate it." ”

After the jade plate was handed over to Fang Han, the old man stopped talking, and turned around and left very interestingly.

Seeing the old man leave and walk out of the refining room, Fang Han urged the jade plate to seal the stone door.

Put away the jade talisman in his hand and came to the side of the Dan furnace, pinched the magic trick and shot out a finger of spiritual light, and landed on the fire mouth below the smelting furnace.

The fire mouth below the furnace was urged by Fang Han's mana aura, and with a snort, a purple flame the thickness of an arm appeared.

As soon as this purple seedling appeared, it immediately caused the temperature in the room to rise instantly, and it became hot.

Patted the storage bag on his waist, and took out the heptyl gold materials used to refine the four swords, gold, ice, wind, and thunder, four different rare heptane gold materials, and appeared on the ground.

With a wave of his big hand, he threw the metallic heptyl gold material into the melting furnace and began to refine the metallic flying sword.

More than a month later, Fang Han in the Earth Fire Room finished refining the last Gengjin material in his hand and refined the last sword thunder attribute flying sword.

Playing with the thunder attribute flying sword in his hand, feeling the powerful spiritual power fluctuations permeating the flying sword, Fang Han felt it, "It's really worthy of the mutation attribute refining the flying sword, and the effect of holding it in your hand is different." ”

After playing for a while, Fang Han held his chin in his hand and pondered what name he should give to the flying sword and sword array in his hand.

It is definitely not possible to call the original name Tiangang Thirty-six Sword Formation, he does not have thirty-six flying swords in his hands, only four flying swords with different attributes Gengjin refining flying swords.

It can't just be called the Four Heavens Small Sword Formation, the name Four Heavens Small Sword Formation doesn't sound good at first.

"It's better to call it the Zhuxian Sword Array."

Fang Han thought about it, and thought of this name for the first time.

Metallic flying sword, the gold lord kills and kills is called Zhuxian Sword.

The thunder attribute flying sword is the strongest attribute among the many attributes of the five element mutations, and it is called the Killing Immortal Sword.

Ice attribute flying sword, trapped immortal sword; Wind attribute flying sword, absolute immortal sword.

In one breath, Fang Han gave four different names to four flying swords with different attributes one after another, and carved the names of the swords on the body of the swords.

"Zhu Xian!"

"Kill the Immortals!"

"Trapped Immortals!"

"Absolute Immortal!"

"Zhuxian Sword Formation, up!"

Fang Han's sleeves waved, and his sword pointed out.

Zhu Immortal Sword, Killing Immortal Sword, Trapping Immortal Sword, and Absolute Immortal Sword, these four used rare Gengjin to refine flying swords, and when they received Fang Han's call, the sword body trembled slightly, and there was a buzzing sound under the flash of spiritual light, and it flew up and spun around Fang Han's body.

Looking at the four flying swords rotating around his body, Fang Han's face was overjoyed, and he manipulated the four flying swords around his body to practice the sword formation in the earth fire room according to what was written in the sword art book.

Seven days later, Fang Han walked out of the earth fire room to return the jade plate to the old man, and returned to the previous hall with the help of the teleportation array.

Stepping on the medium-grade flying sword magic weapon Edgeworth flew out of here, and returned to the room to practice the sword technique.

A month later, Fang Han welcomed his first guest, who was Wu Fan, who lived near him.

Wu Fan, a disciple of Qingyun Peak, is a fifth-level cultivator in the middle stage of the Qi Sea Realm.

"Senior Brother Wu, do you have something to do with me?" Fang Han stood at the door of the small courtyard and said to Wu Fan, who came to visit in front of him.

"Senior Brother Fang, I was entrusted by Senior Brother Cai, and I wanted to invite a few fellow Daoists to go to Miasma Mountain to eliminate demons and complete the bounty task distributed by the sect, this just happened that you live near me, so I immediately thought of you and came to find you."

"So Senior Brother Wu came to me just to invite me to follow Senior Brother Cai in your mouth to participate in the bounty mission issued by the sect?"

"What Senior Brother Fang said is good, would you like to go with me? Senior Brother Cai said that as long as he is willing to go, in addition to dividing the sect equally and distributing task rewards, he can also receive ten spirit stones when he comes back. ”

Listening to Wu Fan's words, Fang Han did not answer immediately, but remained silent in place, thinking about whether it was better for him to go or not.
