Soon after, with the joint efforts of Duan Chen and Tang Jiugu, a tunnel with a length of more than 300 zhang leading directly to the west palace wall of the Northern Xia Palace was excavated by the two.

At the end of the tunnel, there is an incomparably thick black city wall, carved with various complicated formations, shrouded in a faint spiritual light, which is unreal.

I saw Tang Jiugu take out a few finger-thick silver pillars and nail them into the city wall, and ordered: "I will start to break the formation ban on this city wall now, you go back and seal the entrance of the tunnel first, and then pull out those formation flags, so that no one can see the flaws." ”

Duan Chen hurriedly turned around and went back to seal the entrance of the tunnel, restore it to its original state, and pulled out those array flags one by one.

By the time he came back, Tang Jiugu had already cracked the formation on the city wall and dug a gap in the city wall.

The two of them continued to dig tunnels along the gap in the city wall, until they reached a garden in the palace, and Tang Jiugu continued to concoct the formation of sealing the underground of the palace with the formation flag, and dug an exit upward.

After the two of them left the tunnel, they sealed the exit again, pulled out the array flag, and restored everything to its original state.

After doing all this, Tang Jiugu quickly took a look at the surrounding scenery, and immediately planned to take Duan Chen all the way to the east of the Beixia Palace, but as soon as the two of them reached the gate of the garden, they heard a slight voice, coming from far and near.

Tang Jiugu reacted very quickly, and immediately pulled Duan Chen to hide in a corner of the garden, and then waved his hand to sacrifice seven or eight array flags and planted them on the ground, laying out a formation to cover the two figures.

Duan Chen sensed it slightly, and found that the formation laid by Tang Jiugu could not only cover his body, but also have the effect of isolating the detection of the divine sense, and at that moment, he couldn't help but secretly transmit the voice and ask the Seven Demon Monarchs: "Senior, can you arrange this formation of isolating the detection of the divine sense?"

Hearing this, the Seven Demon Lords couldn't help but snort coldly and said, "Stinky boy, are you insulting this Demon Lord?"

Duan Chen hurriedly smiled and said, "The juniors don't dare. ”

The Seven Demon Lords said coldly, "I don't dare to forgive you. ”

After a slight pause, he continued: "Actually, this kind of formation can naturally be taught by the Demon Lord to be laid out, but the key to the problem is that you don't have a formation flag in your hand. ”

Duan Chen said: "This is simple, just wait for the juniors and Jiugu to borrow some array flags to use." ”

However, before Duan Chen could open his mouth to borrow the formation flag from Tang Jiugu, he saw two eunuchs, one old and one young, suddenly walking into the garden, as if they were plotting something.

I saw that one of them was nearly eighty years old, his hair and eyebrows were all white, and the other was a little eunuch of seventeen or eighteen years old, who was reporting something to the old eunuch with a respectful face.

Duan Chen listened attentively, and heard the little eunuch speak: "Master, we have been waiting for Zhu San and San in this garden, why hasn't he come yet?"

The white-eyed old eunuch couldn't help frowning when he heard this: "As the saying goes, everything can't be more than three, then Zhu San didn't come to meet us at the agreed hour for three consecutive nights, I'm afraid that something has happened to him." ”

When the little eunuch heard this, he was shocked and said, "Could it be that the demon dust wind has already discovered that Zhu San has secretly taken refuge in Grandma Tong?"

The white-eyed old eunuch nodded and said, "If nothing else, I'm afraid he is already dead." ”

Duan Chen overheard this, and couldn't help nodding secretly, that Zhu San was indeed dead, after all, he had seen Zhu San killed by Mrs. Zhuang with his own eyes.

Of course, Duan Chen later also dealt with that Mrs. Zhuang.

After a while, I heard the little eunuch exclaim: "Master, will Zhu San sell us and Grandma Tong out because of the East Window incident?"

The white-eyed old eunuch continued: "You mean, Zhu San did not die, but chose to betray Grandma Tong and rejoin the demon dust?"

The little eunuch said in a deep voice: "It's not that this is not possible. ”

The white-eyed old eunuch pondered for a moment and said: "The possibility you said is not very big, let's not say that Zhu San is just a small character, just say that he has betrayed the demon dust wind once, how can the demon dust wind use him again?"

"And if Zhu San really takes refuge in Demon Dust Wind, I'm afraid that when we wait for him in this garden the first night, we will already be arrested by the people sent by Demon Dust Wind. ”

The little eunuch seemed to be stunned for a moment, and did not speak for a long time.

When Duan Chen heard this, he could basically determine that the old eunuch with white eyebrows and hair must be the Gonggong Zheng mentioned on the letterhead.

It's just that he still doesn't know what happened to this Gonggong Zheng and Na Zhu San who made an appointment to meet here.

However, at present, it seems that this Jiang is really older and spicier, although this Zheng Gonggong is unfounded, but in a few words, he is sure that Zhu San has encountered an accident.

At this time, I only heard the little eunuch ask: "Master, if something really happens to Zhu San, then what should we do next?

Gonggong Zheng shook his head and said, "Grandma Tong is chasing and killing the Four Rings Master of the Hanging Temple that day during this time, and I am afraid that I will not have time to take time to deal with this matter." In this way, you go to the harem and report this matter to the two adults, the Demon Grandma and the Immortal Grandma, and see how the two adults decide. ”

The little eunuch nodded and asked casually, "What about you, master?"

Gonggong Zheng said lightly: "The king has recently cultivated great achievements, but I am afraid that he will have to go out of the customs today and tomorrow, so I have to rush to prepare and prepare, lest the king go out of the customs and find no one to serve." ”

Duan Chen's face changed slightly when he heard the words of the king, and in his mind, he suddenly imagined the scene of more than 300 people being slaughtered by the Duke of Zhenguo, as well as the family affection that he had lacked for eighteen years, and he couldn't help but feel angry at the moment, eager to see the true face of this Northern Xia monarch.

At this time, Gonggong Zheng had already parted ways with the little eunuch and left on both sides of the garden.

Seeing this, Duan Chen said: "Ninth Aunt, please go to Wenyuan Pavilion to check the historical books first, I will follow that Gonggong Zheng, and I will be back soon." ”

Before the sound fell, the person had already flown up and chased after him, Tang Jiugu reacted a step slower, hesitated in place for a moment, and then chased after him with a long sigh, and did not rush in the direction of Wenyuan Pavilion.

Duan Chen noticed the movement behind him, and when he saw Tang Jiugu chasing after him, he couldn't help but exclaim, "Jiugu, why are you here?"

Tang Jiugu said helplessly: "I'm afraid that your kid is not sober, in case he does something stupid and has an accident, how can you let me go back and explain to Huixian?"

Duan Chen said: "The younger generation is very sober-minded, and he will never do anything unfavorable to himself, so Jiugu can rest assured." ”

Tang Jiugu snorted coldly and said, "What you are doing now is already very dangerous. ”

After a slight pause, he continued: "Okay, you don't have to quibble, I know what you want to do now, but that Northern Xia monarch Ji Yunkong is a fake Dan monk, and his strength is still above me, you can look at him, but you have to stay away." ”

Duan Chen said with a grateful face: "Juniors understand. ”

At that moment, the two of them quietly followed behind Gonggong Zheng, avoiding heavy inspections, and walked towards the depths of the Northern Xia Palace.

It didn't take long for Duan Chen and the others to follow that Gonggong Zheng to the outside of a heavily guarded palace.

From time to time, you can see a group of forbidden army monks patrolling back and forth outside the palace, and the leader of them is still a monk who has built the foundation of the Great Perfection.

Tang Jiugu glanced up at the plaque on the palace, her eyes were slightly condensed, and she murmured: "Ascending Immortal Palace, when did there be such a palace in the Northern Xia Palace, could it be that it was newly built recently?"

At this time, Gonggong Zheng had already walked into the Immortal Ascension Palace.

Duan Chen saw it in his eyes and was anxious in his heart, and couldn't help but ask, "Ninth Aunt, what should I do now?"

Tang Jiugu glanced at the heavily guarded guards around the Ascension Immortal Palace, shook his head and said, "The security around this Ascension Immortal Hall is obviously more stringent than the rest of the palace, we can't take risks, just wait outside." ”

Duan Chen also knew that he couldn't break through in this situation, so he could only sigh helplessly at the moment, and lurked outside the Ascension Immortal Hall with Tang Jiugu to watch the changes.

About half an hour later, just when Duan Chen was waiting a little impatiently, he saw that Gonggong Zheng suddenly walked out of the Ascension Hall and said a few words to the forbidden army monks who were guarding both sides of the hall gate.

Later, a foundation building Dzogchen monk led by him immediately waved his hand and quickly left with all the forbidden army monks.

And after Gonggong Zheng finished all this, he walked back into the Immortal Palace, looking in a hurry.

Duan Chen and Tang Jiugu saw all this in their eyes, and they inevitably felt a burst of doubts in their hearts, they didn't know what kind of medicine was sold in this Zheng Gonggong's gourd, but the forbidden army monk who guarded the Ascension Immortal Hall was taken away by Zheng Gonggong, but it did the two of them a great favor.

When the two of them confirmed again that all the forbidden army monks had gone away, they immediately quickly sneaked into the Ascending Immortal Palace.

This is an incomparably vast palace, after Duan Chen and Tang Jiugu sneaked into the palace, they explored it for a long time, only to find that there is a cave in this Immortal Ascension Palace, in the depths of this hall, there is actually a hidden passage to the underground, and you can vaguely hear bursts of roars that look like people and non-people, like beasts and not beasts, and the sound is getting louder and louder.

It's no wonder that Gonggong Zheng wants to take the forbidden army monks outside, if they hear the roar coming from this tunnel, even if they don't dare to enter to investigate because of the order, they are afraid that there will be countless doubts and speculations in their hearts.

At this time, he only heard the roar coming from the tunnel getting louder and louder, implying a hint of madness, which made Duan Chen's heart more and more curious about the secret hidden in this tunnel.

At that moment, he sacrificed a phantom talisman body, and entered the tunnel to investigate the situation first, and when he was sure that there was no one guarding the tunnel, he quietly took Tang Jiugu into the tunnel and came to an empty underground palace.

Like the outside, there didn't seem to be anyone guarding this underground palace, Duan Chen's eyes looked around, and his eyebrows raised slightly.

It can be clearly felt that the air in this underground palace is filled with a strong demonic aura, and the nearby ground and walls are also faintly filled with a smell of blood, as if something happened here not long ago.

And in the depths of the dungeon, there is a passage that connects to the deeper places, and the incomparably terrifying and crazy roar comes from that passage.

Duan Chen and Tang Jiugu glanced at each other, and immediately sneaked over, and after a short time, they came to the end of the passage and quietly poked their heads to look inside.
