Miao Zhen immediately walked in front of the sarcophagus of the Yellow Emperor and the ancestor, looked at the little county lord, and immediately stretched the sword body in his hand into the sarcophagus of the ancestor, and saw that the moment the sword body touched the body of the ancestor, he saw several silver needles flying out of the armor decorated with the ancestor's body, and flew up with a bang, and shot directly into the stone wall of the ceiling, and was deeply embedded in the stone wall.

Dao Yan asked, "Miao Zhen, what happened?"

Miao Zhen said: "Master! The little county lord and I just wanted to try to see if the four guards of the Yellow Emperor had installed a mechanism for the wife and ancestor, and sure enough, although the Yellow Emperor died unexpectedly, the four elephant guards still let the ancestor accompany him according to the Yellow Emperor's wishes. I suspect that the exit mechanism may be hidden inside the sarcophagus of the Yellow Emperor and his ancestors. ”

Dao Yan thought for a while and said, "Well! It makes sense! I still remember the humanoid cemetery recorded in the book that day, maybe this mechanism is in this sarcophagus." Miao Zhen, you then try the sarcophagus of the Yellow Emperor. ”

Miao Zhen agreed, followed suit again, and put the sword into the Yellow Emperor's sarcophagus, but found that the Yellow Emperor's golden helmet and golden armor were touched and there was no reaction at all. Miao Zhen looked at Dao Yan, Dao Yan also looked at Miao Zhen, walked over slowly, put his hand under the Yellow Emperor's golden helmet and gold armor and touched it for a long time, at this time, Miao Zhen and the little county lord and others all sweated for Dao Yan, for fear that some secret weapon would fly out again and hurt him.

After a while, Dao Yan suddenly smiled, retracted his hand, and said with a smile: "Ah Zhen! you are really wise this time, the secret key to the exit should be under the armor of the Yellow Emperor." ”

When Miao Zhen and the others heard this, they immediately became excited, and hurriedly asked, "What should we do, Master!"

Dao Yan said: "Take out all the armor of the Yellow Emperor." ”

When Miao Zhen heard this, he immediately walked to the sarcophagus of the Yellow Emperor, took out all the golden helmets and armor of the Yellow Emperor, and put them on the ground next to him. And these five stone holes are exactly the limbs and hearts of the Yellow Emperor's humanoid.

Dao Yan laughed and said, "Haha! This is the essence of the Heavenly Demon Earth Palace's humanoid graveyard, and there is only one location where the secret key is really opened. ”

The little county lord, Miao Zhen and the others immediately looked inside, and sure enough, a human figure and five stone holes appeared in the sarcophagus. Hong Yutang looked at the old man for a long time and said, "Master, these five stone holes are the holes of the secret key, where is the secret key?"

Dao Yan smiled and said, "Lord Humboldt, don't worry, the key will come soon." ”

Hong Yutang said confusedly, "Coming soon?"

At this moment, I saw Gu Xiaonan, Xuan Ming, and Qingyan running in.

Dao Yan immediately smiled and said, "The key is here!"

As soon as Gu Xiaonan and the three of them came in, they saw that everyone was gathered around the sarcophagus of the Yellow Emperor and the concubine ancestor, so they hurriedly asked: "Master, have you found the exit?" We have already taken back the Northern Underworld Magic Weapon, that Runan Hou Mei Sizu has been killed by Xuan Ming, and the remaining blood demons and those remnants of the defeated generals have been entangled by the true body of the four elephants. ”

Dao Yan said to everyone: "Haha! Great, Tianwu! Quickly bring the secret key, then the Northern Underworld Artifact is." ”

At this time, everyone suddenly realized that the turtle and snake were the same body of the Northern Underworld magic weapon to ward off evil spirits was the secret key. Gu Xiaonan then asked, "Master, which of the five holes in this sarcophagus is the real key hole?"

Dao Yan said: "I have already seen the map and the 'Yellow Emperor Imperial Dragon Bintian Map', and the secret key is the location of the humanoid heart, you see." "Anyway, Dao Yan overlapped the map in the "Yin Fu Sutra" with the "Yellow Emperor Imperial Dragon Bintian Map", and rushed to the candlelight, at this time, everyone saw the mystery clearly, and sure enough, in the heart of the human-shaped cemetery on the map of the "Yin Fu Sutra", the dragon eye mark of the "Yellow Emperor Imperial Dragon Bintian Map" vaguely appeared.

Dao Yan continued: "All this is done by Emperor Zhenwu, he is the wizard of the Yellow Emperor, so after the death of the Yellow Emperor, the Emperor Zhenwu led the four elephants to build the Yellow Tomb, and built the mausoleum of the Yellow Emperor according to the human-shaped cemetery of the underground palace, and was also buried here after the death of the ancestor. The Northern Spiritual Weapon was placed in the Yellow Tomb to replace the Yellow Emperor's true body, to obtain the effect of warding off evil spirits, sealing the mana of the Heavenly Demon, and then, he buried the four elephants, and then went to the Yang Stone Room marked by Mamen to guard the corpse accumulation place, waiting for future generations, and before that, he took the jade talisman of the white tiger out of the mausoleum, waiting for the descendants to find it, and he returned to the mausoleum again to guard the Yellow Tomb. However, the entrance to this underground palace must be here, which is a mystery that the Yellow Emperor and Sixiang have never been able to solve during his lifetime. ”

Gu Xiaonan continued: "This is reasonable, then we will open the secret key and find the underground palace." After that, Gu Xiaonan inserted the Northern Spiritual Weapon into the center hole of the five holes in the Yellow Emperor's sarcophagus. Suddenly, I saw that the scepter of the Northern Spiritual Instrument was just inserted into it, and there was no mistake in the pool, and suddenly I heard a bang, and the stone wall behind the sarcophagus of the Yellow Emperor and his ancestor that used to be hung with the 'Yellow Emperor Imperial Dragon Bintian Map' immediately cracked a gap from the middle, and it became bigger and bigger, and after a while, a stone door was opened.

Gu Xiaonan and the others were really surprised, it turned out that this was the gate of the Heavenly Demon's underground palace. At this moment, I saw the wind gusting inside, the green light flickering on and off, and the sound of ghosts crying wolves from the depths came from the depths. Frightened, Xue Qiao and the little county lord hid directly behind Gu Xiaonan and Xuan Ming, and Gu Xiaonan and the others immediately stood in front of everyone.

At this time, Gu Xiaonan asked, "Master, is this really the entrance to the Heavenly Demon Underground Palace? Is the true body of the Jiuli Heavenly Demon inside?"

Dao Yan nodded and said, "This is the place where the real demonic power begins! Everything before was the Nine Great Gates set up by the True Martial Emperor in order to test us, and our next step is to be more auspicious!"

Qingyan said: "Since we are already here, we must go down and have a look, after all, we are the reincarnation of the four elephants, and getting rid of these demons is what we should do." ”

Gu Xiaonan also nodded and said, "Okay! Let's go down." ”

Dao Yan said: "Slow! This time we go down to the underground palace to be more auspicious, it is inconvenient for us to go down with so many people, Tianwu! Xuanming! Qingyan! I will go down with you, Miao Zhen! You and Lord Humboldt protect King Yan, Xue Qiao, Lord Xiaojun and Xin Yao, and pick us up here." ”

As soon as Xue Qiao and the little county lord heard that they would not let themselves go down, they immediately began to cry, and they had to go down to the underground palace with Gu Xiaonan and Xuan Ming.
