Su Fan actually didn't think too much. The Sumeru stone in his hand was not big.

The space the size of Zhenyuanfeng Square is not as big as the secret treasure left by Immortal Tianfu.

Although it is a small world independent of the fairy world, the Sumeru stone using this method can only be fixed in the small world and cannot be carried around.

The Sumeru stone created with the second method has limited space, but it can be carried around and can be entered and exited at any time.

For Su Fan who lacked magical means, this was simply a pillow for him when he was sleepy and rice for him when he was hungry, which was perfect.

Although Su Fan is not afraid of the Immortal Emperor now, if he encounters someone who is difficult to deal with, he can just go into this small world and wait for ten days and a half. When he recovers his strength, he will come out again and he will be a hero again.

However, although Zhouzhuang knew the method of refining Sumeru Stone, the specific operation still needed to be completed by Tang Mengdong.

So, Su Fan and Zhou Zhuang walked towards Yanhuo Peak together.

…

…

…

Yanhuo Peak, Weapon Refining Pavilion.

During this period, Tang Mengdong had one head and two heads.

He read a lot of the Immortal Weapon Forging Manual that his uncle brought back and studied it a lot.

Uncle Master used up a lot of his fairy crystals.

But the first-grade immortal treasure cannot be refined.

Although the Haotian Sect has many spiritual crystals, the number of immortal crystals is limited.

They were all trophies captured by Su Fan from Huntian Immortal City.

Most fairy crystals come from the Qiankun Ring of Immortal Emperor Huntian.

"Old Tang... why don't you take a break? You haven't had a break for more than a month. I see your hair has turned a lot gray."

Next to the Earth Fire Pond, Xiao Huo, who had shrunk in size and had a much more solid spirit, sat beside the Earth Fire Pond.

The eyes composed of incandescent flames looked at Tang Mengdong helplessly.

Although the Flame Demon King was coerced by the Heavenly Dao Oath, he had no choice but to come to Haotian Sect to work.

But Su Fan didn't treat him badly. Not only did he give him a holy blood pill, he also helped him survive the thunder tribulation and ascended to become a true immortal.

You know, any demon cultivator will suffer several times more damage than an ordinary cultivator when faced with thunder.

The Flame Demon King alone cannot survive the thunder tribulation.

However, in order to allow him to work in the Earth Fire Pond with peace of mind, Tang Mengdong took the initiative and used a lightning rod to help the Fire Demon King out of trouble.

This is better.

The grateful eyes of the Flame Demon King flowed with magma.

The flame temperature of the ground fire pool suddenly rose several levels.

If we say that in the past, the Flame Demon King still worked in the Haotian Sect unwillingly.

Now he is stuck in the Earth Fire Pond and won't leave.

The Yanhuo Demon Clan has not produced a true immortal for generations.

Now let him do it.

So easy.

If you don't hold onto the Haotian Sect's thigh, you are definitely a fool.

"Have a rest, my uncle gave me such a good condition, but I can't even make a first-grade immortal treasure. It's so embarrassing!"

Wiping the sweat from his head, Tang Mengdong took out the fairy world and forging materials again, preparing to continue trying to forge a first-grade fairy treasure lightning rod.

The Flame Demon King was a little helpless. Although he didn't like humans very much, after working with Tang Mengdong for a long time, the Flame Demon King naturally understood his personality.

The two had similar temperaments and soon became good friends.

"Senior Su won't blame you if you work so hard."

The Flame Demon King was a little helpless.

There is a molten fire core at the bottom of the earthly fire pool, which is the sacred object of their flame-fire demon clan, with the blessing of the molten fire core.

As long as the Flame Demon King stays in the Earth Fire Pond, even if he is not practicing, his body will automatically gather immortal energy and slowly improve his cultivation level.

"It's not a matter of working hard or not, what I want is the result!"

Tang Mengdong was sweating profusely on the forging platform, and the Flame Demon King skillfully provided him with high-temperature earth fire, and they were in perfect harmony with each other.

At this moment, not far away suddenly

There was a sound of hurried footsteps, and then the Yanhuo Peak disciples came to the edge of the Earth Fire Pond with anxious expressions on their faces, and saluted Tang Mengdong.

"master!"

"Mo Chen, why are you here?"

Tang Mengdong stopped what he was doing and looked at Mo Chen with some confusion.

"Master, Master, this old man is here. He is already on the mountainside of Yanhuo Peak. He is here with Elder Zhouzhuang."

"!!!"

Upon hearing this, Tang Mengdong's hands trembled, and the immortal crystal that had just softened almost fell to the ground.

"I'm going. Why didn't you tell me earlier when my uncle was here? This is going to be terrible."

"Master, my disciple accidentally discovered it just now, so I came to inform you quickly."

Mo Chen said quickly.

"I know, I know, well done."

Putting down the work at hand, Tang Mengdong's immortal power surged slightly.

He evaporated the sweat from his exposed upper body, put on a coat, and walked out of the Refining Pavilion.

Hearing that Su Fan was coming, the Flame Demon King quickly jumped into the earthly fire pool and straightened up his appearance.

On the other side, as soon as Su Fan and Zhou Zhuang reached the gate of Yanhuo Peak Weapon Refining Pavilion, they saw Tang Mengdong and Mo Chen coming out.

"Uncle Master is here, but Mengdong is a long way from greeting you! Please forgive me, Uncle Master."

Tang Mengdong didn't refine the Immortal Treasure, so he felt guilty. When he saw Su Fan coming, he thought that his uncle was here to ask for punishment, so he hurriedly confessed first.

"It doesn't matter, it doesn't matter. I met Mo Chen when I was going up the mountain just now. He told you that I was coming over."

Su Fan smiled slightly. Although Tang Mengdong didn't have much sweat on his body, his face was red. You could feel the high temperature on his body from a long distance away. He must have been working in forging just now.

"Exactly! Mengdong is stupid, please ask your uncle to blame him!"

"Huh? Dumb? What the hell?"

Seeing Tang Mengdong's guilty look, Su Fan was confused.

He didn't seem to say anything.

"Uncle Master, didn't you come here today to ask questions?"

Tang Mengdong frowned, a little confused.

"Why did you ask for a crime? What crime did you ask for?"

Su Fan scratched his head.

"Don't be paranoid about being persecuted. I came to you today for other reasons."

Tang Mengdong breathed a sigh of relief.

"I thought it was because I haven't refined the immortal treasure for so many days, so uncle, you are angry."

Su Fan: "..."

Am I so stingy?

Damn it, isn’t my image in the eyes of my nephews a kind, considerate, and approachable gentle teacher?

Why have you become so petty?

"Oh, nephew Mengdong, you think too much."

Su Fan sighed, walked to Tang Mengdong, and patted his shoulder.

"Those blacksmithing classics, Shangyan said, are all exquisite. Ordinary people can think about them for decades or hundreds of years. There are many people who have spent thousands of years on them. How long have you been here? Don't worry about it."

Tang Mengdong: "!!!"

"Besides, weapon refining requires a smooth process and a balance between work and rest. It looks like you haven't rested for a long time, right?"

Tang Mengdong nodded sheepishly.

"Uncle Master is right. During this time, I have been having a headache about the Immortal Treasure, and I haven't left the Weapon Refining Pavilion very often."
