If I tell you that a mortal body invented a mortal thing, but it can change the world, I'm afraid no one will believe it.

Is the truth simple?

The great elder's face showed an extremely surprised look, "Unbelievable, unimaginable!"

"Ah!"

Captain Yao Mengji sighed, with loneliness and great regret: "When I visited the master yesterday, the master also explained to me the truth of lightning rods, static electricity, conductors, and pathways. Unfortunately, my comprehension is too poor and my strength is not enough. I didn't understand a word. Otherwise, I might be able to comprehend the great truth from it."

Zhou Dacheng said: "How can the master's words be so easy to comprehend? Most likely, the level is too high."

Yao Mengji suddenly asked: "By the way, the world has changed drastically. Have you contacted the ancestors of Linxian Dao Palace?"

Qin Manyun said: "Master, we have tried to contact them."

"How is it?"

Qin Manyun frowned slightly and said, "It is indeed no longer as unresponsive as before, but although the ancestral tablet has lit up, it is still difficult to communicate with the ancestors as before."

"It seems that the road between immortals and mortals has indeed begun to open up."

Yao Mengji nodded, and then said, "I guess it may be because the great changes in the world have just begun, so most of the roads between immortals and mortals are still cut off, and the cost we have spent is not large enough, so we have not been able to contact. There is no rush for this matter, just wait for future developments."

At the same time, in Qingyun Valley.

In the deepest part of the underground of the hall.

The space here is extremely large, but it is empty, with only three things in total.

A long wooden table, a milky white stone, and a stove burning incense.

Gu Changqing brought Gu Ziyao and his sister and brother, and three elders from Qingyun Valley beside them. They stood respectfully in front of the wooden table, all with solemn expressions.

"Okay, let's get started!"

Gu Changqing took a deep breath and walked slowly forward.

He first bowed three times to the milky white stone in front of the wooden table, then bit his tongue and spurted out a mouthful of blood, which sprinkled on the stone.

Suddenly, the milky white stone began to emit light, illuminating the entire room.

Gu Changqing and others were all shocked, and then they did not dare to neglect it, and quickly picked up the long incense and lit it.

Then he held the long incense stick respectfully and said devoutly: "Gu Changqing, the eleventh generation master of Qingyun Valley, invites the ancestors to come!"

As the voice fell, the smoke from the long incense stick began to change direction, no longer upward, but horizontally, floating towards the milky white stone. The smoke merged into the stone, and suddenly it became bright.

The blood on it also shrank rapidly at a speed visible to the naked eye.

Everyone held their breath, not daring to breathe, and was extremely nervous.

"Buzz!"

In the void, waves of ripples rippled, like ripples in space, and a vast and boundless breath suddenly surged into the whole scene.

Immediately afterwards, the milky white stone shone to its extreme, and the light shot straight into the sky. Then, above the light, an illusory figure slowly emerged.

The figure was in a trance for a moment, then was slightly stunned and asked, "Changqing?"

Gu Changqing's eyes suddenly turned red, as if he had seen his dearest relative. He couldn't help but take two steps forward and choked up, "Grandpa!"

The phantom's eyes suddenly turned red as well, and he said excitedly, "It's really you, my dear grandson!"

Gu Changqing hurriedly called Gu Ziyao and his sister over, "Grandpa, these are my sons and daughters, Gu Ziyao and Gu Ziyu, you two should hurry up and meet our great-grandfather."

Gu Ziyao and his sister were extremely nervous, and said stiffly, "Great-grandfather."

"Hahaha, both sons and daughters are here, not bad!" The phantom couldn't help laughing, and was shaking with excitement.

After laughing for a while, the phantom said, "By the way, where is your father? I remember that when I ascended, he should have reached the peak of tribulation."

Gu Changqing's eyes darkened, and he sighed, "Three thousand years ago, the demons were rampant, and they took advantage of my father's demon-sealing period to come and do evil. Although they were eventually suppressed, my father also died."

The phantom also showed a sad expression, and then sighed, "For cultivators of my generation, life and death are normal. Including you, there are eleven generations of valley masters in Qingyun Valley. , which one of them is not a brilliant and talented person? There are only three people who can truly ascend to become immortals, including me! The road to becoming an immortal is uncertain and the future is uncertain. Countless cultivators have been buried along the way! "

Gu Changqing gritted his teeth and said, "Three thousand years ago, because the demons knew that the road between immortals and mortals was cut off and we could not invite immortals to descend, they dared to attack Qingyun Valley recklessly. That year, there was a bloody storm in almost the entire immortal cultivation world, with countless deaths and injuries. It was really abominable!"

"For so many years, the road between immortals and mortals has been cut off, and the mortal world has weakened, which has indeed given the demon world an opportunity to take advantage of it. Fortunately, you have held on."

The shadow was surprised, "I just didn't expect that the road between immortals and mortals would actually show signs of being reopened."

"Grandpa, I do know something about this. A..." Gu Changqing trembled in awe and said, "A saint!"

"Saint... Saint?"

The phantom couldn't help but shook his head, and said with a smile: "Impossible, let alone the mortal world, even in the current fairyland, saints only exist in legends. I'm afraid such people only existed in ancient times. Your knowledge is really too shallow. It's better not to say such ignorant words. It's good to become a laughing stock. You may even offend a real saint."

Gu Changqing hurriedly said: "Grandpa, I'm serious! A few days ago, the ancestor of the Liu family came and was directly killed by the calligraphy of that master. Not only that, he also poked a hole in the sky! I was there!"

The shadow shook twice in shock, "The ancestor of the Liu family was only at the initial stage of the immortal cultivation. There are many people who can kill him, but to break the barrier between immortals and mortals from the mortal world, this kind of method, could it be a golden immortal? Or did he use some special magic weapon left in the mortal world from ancient times? There should be no such a powerful person in the mortal world!"

He thought about various possibilities. If it weren't for the fact that Gu Changqing was his grandson and he had full trust in Gu Changqing, he would probably have regarded it as nonsense.

Gu Changqing gritted his teeth and said, "Grandpa, that master also left a painting."

"Oh? Show it to me quickly, maybe I can guess its strength and see if it's true or not." The shadow immediately became interested and said impatiently.

Gu Changqing solemnly took out the scroll and reminded him, "Please be prepared, Grandpa."

The shadow smiled slightly and said proudly, "No need, the first generation of the master of my Qingyun Valley ascended to heaven, he was brilliant and brilliant, and he also founded a sect in the fairy world. Although I have no blood relationship with him, but we are both from Qingyun Valley, he takes good care of me, so I am naturally doing well. Just open it?"

Gu Changqing nodded, holding the scroll and slowly spreading it out.

Suddenly, the golden sun shone, and the sky was full of golden flames that swept down from the scroll.

Gu Changqing's realm was not high enough, so he did not feel this kind of pressure deeply, but the phantom was stunned. The scroll was only halfway opened, and he felt a huge and boundless breath pressing down on him, making his brain buzz and almost losing consciousness.

Majestic, sacred, terrifying, and... burning!

Too scary, too horrifying!

In just a moment, the phantom had almost become illusory and turned into air. An extremely weak voice came urgently, "Stop! Don't open it again, I can't bear it! Close the scroll quickly, summon me again, summon me again..."
