"The Secret Realm of the Sky!" Yuan Tiangang browed when he heard this.

"Master Yuan knows which secret realm?" Chen Luo asked when he saw this.

"I accidentally saw it in the classics. It was a famous place for immortal burials, so I don't know more about the situation." Yuan Tiangang shook his head and said.

"The place of immortal burial is indeed very appropriate." Chen Luo couldn't help but think in his heart.

"I have time to explain the situation there in the future. I will report to you two in detail. I will report to the Duke and Master Yuan for another important matter." He quickly came back to his senses and said.

"Oh, if you have something, just say it." Yuan Tiangang waved his whisk and nodded.

"I just returned to Chang'an City and learned from the ancient Taoist fellow that the hydrological officials of the Imperial Heaven Supervision were killed and the changes in the earth's veins. One of the modified earth's veins leads to the Yinling Mountains northwest of Chang'an City. I once went to an ancient tomb there, and there was a space passage to the underworld at the bottom of the tomb." Chen Luo stopped here, with the wisdom of Yuan Tiangang and Cheng Yaojin, he did not need further statements.

Sure enough, Cheng Yaojin's face froze when he heard this.

Yuan Tiangang's expression was still calm and he showed no surprise.

"Could Yuan Tiangang have known about this for a long time?" Chen Luo couldn't help but think inwardly when he saw this.

"This is the hydrological diagram of the ground veins that have just been drawn, and the investigation results of the junior investigation into the hydrological officials of the Imperial Heaven Supervision." Gu Hualing took out the hydrological diagram and a jade slip and sent it to Yuan and Cheng in front of them.

Cheng Yaojin eagerly took the hydrological pictures and jade slips, and his spiritual sense swept away his face and looked ugly.

"According to the situation of the previous battle, the enemy has the ability to summon underground demons. Now they have opened up a channel connecting the underworld. Eighty-years-old to make a comeback and summon ghosts from the underworld to attack Chang'an City again, and they must try to stop it!" Cheng Yaojin looked at Yuan Tiangang.

"Thank you for your hard work in the ancient Taoist fellow." Yuan Tiangang was still not in a hurry. He took the hydrological drawings of the earth veins and jade slips, glanced at it and said to Gu Hualing.

Gu Hualing was stunned, and then understood that Yuan Tiangang was asking her to go out.

"Then I will say goodbye first." Gu Hualing bowed slightly, glared at Chen Luo next to him, and then walked out.

Yuan Tiangang waved his sleeves, and a layer of white light flooded the hall.

"Master Yuan, is there something else in the matter of the earth veins?" Chen Luo asked with surprise when he saw this.

"This matter involves a lot, and it's a long story. I heard that you were there when Fangcunshan was attacked. Do you know the real reason why Shitu Ridge and Demon King Village attacked Fangcunshan?" Yuan Tiangang asked in a flash.

"I know a little bit, it is said that it is to enter a place called the Well of Gods and Demons. The entrance is in the Bodhi Secret Realm of Fangcun Mountain." Chen Luo didn't understand why Yuan Tiangang suddenly mentioned the incident of Fangcun Mountain, but he still said the truth.

"That's right, the Well of Gods and Demons is the hub of spiritual energy and demons in the three realms. After the ancient battle of the Gods, all races in the three realms worked together to seal it. But over the years, the people who have been thinking about the Well of Gods and Demons have never cut off." Yuan Tiangang said.

"I can imagine this, but isn't the entrance to the Well of Gods and Demons in the Bodhi Secret Realm? The entrance should have been sealed after the war. What does it have to do with Chang'an City?" Chen Luo said in confusion.

"There is more than one entrance to the Well of Gods and Demons, and there is also an entrance here in Chang'an City." Cheng Yaojin said.

"What!" Chen Luo was shocked when he heard this.

He opened his mouth and subconsciously wanted to ask where the entrance to the Well of Gods and Demons was, but he swallowed it back.

Such important secrets must be kept strictly confidential and cannot be spread casually.

"What do you mean by the riots before Chang'an City, and the changes in the earth veins today, are some people trying to open the entrance to the well of Gods and Demons?" Chen Luo calmed down and asked.

"Yes, they probably haven't found the entrance to the Well of Gods and Demons. They had previously driven the underground suppression of Chang'an City to attack the people in the city, trying to use the blood sacrifice method to explore the entire Chang'an City, and were stopped. Now they probably want to use the same trick again." Yuan Tiangang said.

"Before, demons attacked the city, wasn't the Jinghe Dragon King trying to destroy the Tang Dynasty's dragon veins? Did he take it for himself?" Chen Luo said in surprise.

"That's just a superficial reason. I have investigated it carefully afterwards. There is a blood sacrifice array carved deep in Chang'an City. It can use essence, blood and resentment to filth the earth's veins. At the same time, it explores everything in the city. The Dragon King of Jinghe was only used. Fortunately, the killing that day was stopped in time, and the blood sacrifice array stopped halfway." Yuan Tiangang said.

"That's good." Chen Luo's expression relaxed.

"Even so, we have no way of knowing whether the Blood Sacrifice Magic Formation has begun to explore and how large the scope has been investigated. For the sake of this, we can only try our best to protect the entrance of the Well of Gods and Demons. I summoned masters from various sects here for this reason." Yuan Tiangang said.

"What the national master said is reasonable, but the earth veins leading to the Yinling Mountains will be cut off or sealed no matter what," Chen Luo said.

"Don't worry, I just heard about this, and I have sent someone to deal with it." Yuan Tiangang said with a faint smile.

Chen Luo breathed a sigh of relief when he heard this.

"So you have sent someone to go, that's fine." Cheng Yaojin said.

"Two seniors, please tell me about this, but if you have something to do, I need my service?" Chen Luo looked at the two and asked.

"Yes, what's going on now..." Yuan Tiangang said.

But as soon as he said halfway, the ground suddenly shaking violently, and loud roars penetrated the white light around him and passed in.

Yuan Tiangang suddenly stood up and disappeared from the spot out of thin air, and the white light in the hall also dissipated.

Chen Luo immediately shot outward. Cheng Yaojin was about to get up, but his body suddenly froze there, and a trace of black light appeared in his eyes.

"Hehe, the Heavenly Fox's Heart-Surface Method is indeed mysterious. No one has discovered my existence." A sneer came from Cheng Yaojin's mouth, and a trace of black air appeared on his body, and rushed toward the ground.

He fell and appeared in the air outside the side hall, and his face changed drastically.

The bright sky was covered with thick black clouds before, and meteorite-like fireballs fell from the sky and landed everywhere in Chang'an City.

These fireballs are bright and bright, and they don’t look like ordinary fire. Once they fall to the ground, they explode violently, destroying everything in the surrounding area dozens of feet.

Amid the loud "rumbling" sound, fires lit up everywhere in Chang'an City, countless houses and buildings collapsed, and the shrill cry of the people everywhere.

Shen Luo was shocked and angry, and his feet were lit up, and he disappeared out of thin air from the spot, appearing under a fireball hundreds of feet away, and waved his sleeves.

A golden tower appeared, and it was the Qiankun Xuanhuo Tower. A large piece of golden light appeared at the bottom of the tower, wrapping the fireball.

The huge fireball quickly shrank and sank into the Qiankun Xuanhuo Tower with a "swoosh".

Qiankun Xuanhuo Tower not only has the Six Ding Ding Divine Fire, but also contains the Mysterious Fire Space, which can collect all the fires in the world.
