Gu Qingfeng decided to start practicing the Eternal Night Lamp Burning Technique.

After this battle, he felt deeply that his own strength was too weak. Facing a mere earthly immortal, he was forced to use only 10% of his strength to defeat the opponent. This made him feel deeply uneasy, so he learned from his mistakes and decided to practice hard.

Gu Qingfeng estimated that his strength should be equivalent to that of a celestial immortal, one level higher than an earthly immortal.

Because the earthly immortals are obviously no match for him, as for what position he holds among the celestial immortals, that is unknown, as he has not seen any celestial immortals yet.

He opened the Eternal Night Lamp Lighting Method and began to study it carefully.

Three days later, the profound meaning of the Eternal Night Lamp Lighting Technique was fully understood.

This method is simple and difficult at the same time.

The reason why it’s simple is that this method is very easy to practice, and basically any normal immortal can master it.

But the difficulty lies in the fact that the Eternal Night Lamp Lighting Method requires igniting magic power and purifying impurities. Since it needs to be ignited, flames must be used. The flames here do not refer to earthly flames, but fairy fires.

Fairy fire is extremely rare and precious, and the Eternal Night Lamp Burning Method requires extremely high quality flames.

To be precise, the higher the quality of the flame used to ignite the mana, the stronger the quality of the purified mana will be.

Gu Qingfeng was so happy when he saw this, and said nothing more. He thanked his family and the Xingji Immortal King, and said he would curse for one more hour today so that he could be reunited with his family as soon as possible.

After he was fully prepared, he activated the Star Demon Fire, and the strange purple flame burned fiercely in his dantian.

Afterwards, he controlled the magic power and flames according to the method of Eternal Night Lamp Burning to ignite the magic power.

boom!

The roar of fire seemed to be heard from somewhere in the dark.

Gu Qingfeng's magic power was ignited, and the magic power was burning like oil. After burning, it was not that everything was gone, but what remained was a more crystal clear, high-intensity magic power that seemed to have been compressed.

He felt the magic power forged by fire and was surprised to find that the quality of his magic power was now at least a hundred times higher than before.

A hundred times improvement!!

Is this because the Eternal Night Lamp is too powerful?

No! Mainly thanks to my family!

The Star Demon Fire is indeed the fire from the Immortal King. It is used to refine the magic power of the immortal level. It is simply a nuclear strike, which directly increases the quality of magic power a hundred times.

If Gu Qingfeng's advantage in the past was that he possessed a vast amount of magic power, but the quality was not as good as that of the real immortals or earthly immortals, then it is completely different now. Now he has become bigger and stronger, and his magic power is rough and hard!

However, there is a happy worry, that is, trillions of years of mana are really too much, not to mention that it has devoured so many true immortals and earthly immortals. Even if the Star Demon Fire is very efficient, it will probably take a year to completely refine it.

Gu Qingfeng, who was bored, took out the Demonic Prison Sword of Chu Fengyang, the son of destiny, and began to study it.

The Hell Demon Sword is silver in color, with mysterious and unusual patterns engraved on the sword. No matter from the material or the patterns, no clues can be seen.

The magical thing is that even if he took out the Spear of the Underworld, this top-grade weapon of the Earth Immortal, to attack the Hell Demon Sword, he was still unable to hurt it at all.

From this, it can be seen that the grade of the Hell Demon Sword is definitely not low, but for some reason, its power is not obvious.

It's possible that all the power was used to seal the family inside.

Gu Qingfeng was becoming more and more excited about his family members trapped in the Hell Demon Sword. He couldn't wait to rescue them.

So he probed his soul into the Prison Demon Sword.

boom!

It was like thunder exploding deep in the soul!

Bang!

Gu Qingfeng's soul was directly bounced out.

Damn!

He tried a few more times without giving up, but the result was the same: he was unable to enter the Hell Demon Sword, let alone see the situation inside.

"Family, can you hear me? I am here to save you. If you can hear me, please make a sound."

Gu Qingfeng shouted at the Hell Demon Sword, but after a long time, the air was silent.

"Damn it! I just don't believe that I can't deal with a broken sword like yours."

He took out all kinds of forbidden objects and evil objects that could defile people's magic weapons, and threw them at the Hell Demon Sword in an attempt to break the seal on it.

These things were searched out from Faxu Guiyin and others, and now they come in handy.

However, when the forbidden objects, filthy and evil things dripped onto the Hell Demon Sword, the Hell Demon Sword instantly burst out with an incomparably bright fairy light, annihilating them all.

Gu Qingfeng was a little dumbfounded. He never expected that the sealing power of the Hell Demon Sword was so strong. The brilliant fairy light that just burst out contained an extremely powerful force. Even he couldn't help but feel a little nervous at that power.

The seal was so strong that the family couldn't even imagine it.

He became more and more anxious, but he was helpless. After much thought, he could only call Fairy Miaohua over. After all, she was the one with the highest cultivation among all the women. As an earthly immortal, she must know many ways to break the ban.

Soon, Fairy Miaohua, who was wearing cool clothes and had whip marks on her fair skin, was brought over by the little corpse spirit.

"Miaohua, I have something to ask you. If your answer satisfies me, then today's training will not be necessary."

Miaohua at this time had long lost her former arrogance. Although Gu Qingfeng had not done anything to her during these days, she had experienced the methods of the woman known as the Little Corpse Charm and was afraid of her.

She didn't understand why a woman as beautiful as a fairy could have such a vicious heart. Her methods were simply unheard of and unseen.

What impressed her most was that the little corpse spirit turned into her appearance and went to Gu Qingfeng to pose in a coquettish manner, refreshing her sense of shame every minute and every second.

Therefore, when Miaohua heard that there was no need to train today, she was immediately delighted and answered the questions with full concentration.

"What's the question? Ask it."

Bang!

Miaohua cried out in pain and collapsed to the ground.

The little corpse leaned over, pinched Miaohua's delicate face with his hands, and said with a dangerous light in his eyes: "Have you forgotten the etiquette I taught you? Or do you want to double your training?"

Miaohua was instantly terrified, and quickly got up from the ground and said respectfully to Gu Qingfeng: "Master, please ask, I will tell you everything I know."

Gu Qingfeng nodded in satisfaction and said, "I have a close friend who was sealed in a sword by a villain. This sword is not an ordinary object. Even if I use the forbidden powder, the evil blood stain and other things, I can't break the seal. Do you have any good ideas?"

Miao Hua thought about it and said quickly: "Things like Breaking the Ban and Dispersing the Evil Blood are specifically for seals, but they are not very advanced items after all. If you are facing a powerful seal, you should look for some high-level magic weapons or high-level methods to break the ban."

"Oh?" Gu Qingfeng's eyes lit up. As expected of a mid-level earth immortal, he was well-informed.

"Where can I find it?"

"Mid-galaxy."
