Sign in to Invincible from Butian Pavilion

Chapter 13 The Underworld Infiltrator

That night, Lu Hong ended his short retreat.

In the past three months, after more than ten days of seclusion every time, Lu Hong would combine work and rest to take a good rest.

Ever since breaking through to the tenth level of body training, Lu Hong's physical body, inner strength, and spirit have undergone earth-shaking changes.

The various skills and secret techniques he practiced also evolved accordingly.

Among them, the method of restraining interest has changed greatly!

After a period of stable cultivation, Lu Hong has gradually controlled the skyrocketing cultivation power.

So far, his physical body can already be called "no omission"!

Coupled with the method of restraining interest, no one can discover his true strength!

Even warriors whose cultivation level has not reached a certain level cannot find Lu Hong, even if they pass by Lu Hong's side, they will only think that Lu Hong is air.

So during the several breaks in the past three months, Lu Hong visited several places in Butian Pavilion that he had never been to before.

Dan Building, Qi Building, Tianbao Building and a forbidden place, Yinyuan Valley.

Sign in at the pill building to get a higher level of pill [Sanyang Sanyin Pill].

Signed in at Qilou and obtained the top-grade sword of the spiritual rank [Chiyan Tiansha Dao].

……

At present, most of the pills he signed in and obtained are of human-level quality, and the three-yang and three-yin pills he obtained in the Danlou are low-grade spiritual grades, but obviously, there must be better ones in the Danlou.

If there is a chance, Lu Hong would like to sign in Danlou for a while.

"If you use the reason that your aptitude is not good enough to improve your alchemy, will you let me go to the alchemy building to study for a while?"

Lu Hong thought about this question.

But there is no rush.

Let's talk about it after breaking through to the True Yuan Realm.

"Where are you going tonight?"

Just as Lu Hong was thinking about the map of Butian Pavilion, two figures suddenly flashed in the darkness out of the corner of his eyes.

……

"Junior Brother Zhao, have you found out the way to Zhenyuan Underground Palace?"

"If I'm not sure, how dare I ask Senior Brother Lin to come out." Junior Brother Zhao nodded and bowed in a respectful tone.

"Let's go, take me to have a look." Brother Lin's eyes flashed, and he waved his hand to let Junior Brother Zhao lead the way.

Junior brother Zhao dared not follow, knowing that senior brother Lin wanted to share some of his credit, so he could only lead the way.

The two of them hid their bodies all the way and walked for nearly half an hour before finally stopping.

This is a slightly undulating hill, with verdant trees on and around the hill, tightly covering a cave, if it wasn't for Junior Brother Zhao leading the way, it would be almost impossible to find a cave here.

The hill was surrounded by a large formation, and the formation was so powerful that ordinary warriors in the True Yuan Realm would surely die if they entered it.

But the two seemed to have taken out some treasures, and a layer of dim fluorescent light covered them.

The two entered the cave without causing any changes in the formation.

However, they didn't realize that the coverage of their treasure seemed to be a little bigger than they had imagined.

The cave is not completely dark. The ceiling of the cave is inlaid with shining gemstones. The brightness is similar to that of ordinary candles. In the eyes of several people, it is no different from the daytime.

The cave was twists and turns, and after a few minutes, it came to the end.

The Zhenyuan underground palace is divided into three floors, each suppressing different characters.

At this time, the few people came to the first floor.

As soon as he came to the end of the cave, he felt a mixed force rushing towards his face.

Spiritual energy, demonic energy, demonic energy, etc. were mixed together, making several people almost suffocate.

Brother Lin was ecstatic: "Brother Zhao, great contribution, great contribution!"

"Yes, it is indeed a great contribution."

Brother Lin froze for a moment.

Because what he heard was not Junior Brother Zhao's answer, but a strange voice.

Brother Lin came back to his senses in an instant, and was about to react, but it was too late.

An icy blue long sword pierced his chest, and an icy force instantly froze his heart, and flowed throughout his body along the blood meridians, destroying all vital points.

Lu Hong's figure appeared, with a smile all over his face, he reached out and groped for Senior Brother Lin.

"System, sign in!"

[Congratulations to the host, the sign-in was successful, and the "Demonic Dao Heavenly Court Manual" was obtained. 】

"Big harvest, big harvest!"

Lu Hong smiled even wider, looked back at the end of the cave again, turned and left.

Brother Lin's body lost its support and fell to the ground with a "bang".

……

Elder Peng Gong has been depressed for several days since the last time there was a problem in Zhenyuan Underground Palace due to the unknown reason of Huan Xinhai.

That was an unwarranted disaster!

After that, Elder Peng Gong approached the formation master in Butian Pavilion, and slightly modified the formation to guard the Zhenyuan Underground Palace.

The passage that connects to the Magic Heart Sea has been restricted, and it is no longer allowed to extract the aura of the Zhenyuan Underground Palace.

In the past few months, there have been no accidents, and Elder Peng Gong is relieved.

That night, Elder Peng Gong prepared a pot of wine and several dishes of appetizers, and was having a drink or two with his old friend Elder Lu Gaotong, chatting about the world.

"Old Peng, who is this Empress Dowager?"

Elder Peng Gong's face was rosy, obviously a little drunk.

"I don't care who he is! If he dares to stand up, then I dare to beat him up!" Elder Peng Gong muttered and cursed, "It actually disturbed the Zhenyuan underground palace. If a few of them escaped, then he He is the sinner of Butian Pavilion!"

"belch--"

Lu Gaotong helplessly watched Elder Peng Gong collapsed on the table.

"Swear when you're drunk, the wine is really bad!" Lu Gaotong shook his head and poured himself a glass of wine.

"Ah! Good wine!"

"Lao Peng's wine quality is poor, but he has a good eye for wine selection."

"belch--"

Suddenly, Lu Gaotong's ears moved.

A faint "bang" came to his ears.

Lu Gaotong was instantly alert.

Elder Peng Gong also woke up instantly.

"Who!"

The two of them disappeared in a flash.

In the cave, the figures of the two appeared at the same time.

In an instant, his eyes were on the two corpses on the ground.

"There's nothing of value on him."

Elder Peng Gong checked it and gave a conclusion.

"Both of them pierced their hearts with a sword, and they froze to death in an instant. They couldn't identify who the murderer was."

However, Lu Gaotong recognized their identities: "These two seem to be disciples of Elder Li and Elder Nangong."

The two looked at each other with serious eyes.

where is this place?

Within the guardian formation of Zhenyuan Underground Palace!

It can be called one of the most important forbidden areas of Butian Pavilion!

Why did two mere disciples dare to come here?

Why can you come here?

Who gave them the guts?

And who let them in?

"Old Peng, you stay here, I will report to the Pavilion Master."

Elder Peng Gong nodded: "Okay, but Lao Lu, you have to be careful on the road!"

Lu Gao's heart shuddered.

He understood what Peng Gong meant.

If the murderer has any intentions, those who are waiting outside...

"I will pay attention." Lu Gaotong hurriedly left to find the master of Butian Pavilion.

Peng Gong stood there guarding the two corpses, his expression very ugly.

"If I find out who did it, I want him to look good!"

In the empty cave, the impotent fury of Elder Peng Gong echoed.
