The Burial Tower of Immortals buries the heavens, the earth, and all the immortals.

The journey to the northern border was long, and Qin Changye and his party traveled without stopping.

Soon, a valley filled with black mist, so dark that one could hardly see their hand in front of their face, blocked their path.

"This is the Heavenly Demon Valley."

Ren Pingsheng unfolded the map, pointed to the area covered by black marks, and his expression became unusually solemn: "Tianyao Valley is the only way to the Northern Territory. It is called this because an extremely powerful demon beast sleeps in the valley. It is said to be a silver eagle that has reached the fifth level and is the king of the silver eagle clan. It should have been ambushed by other silver eagles during the change of the throne and left in this valley after its defeat."

Both the demonic beasts and the savage beasts that the barbarian kingdom is most skilled at taming belong to the category of spirit beasts.

"This silver eagle was not only seriously injured, but it was also emitting black smoke. Over time, the valley was filled with thick black smoke."

Ren Pingsheng continued, "This silver eagle is, after all, a level five demon beast, and it also possesses the bloodline of a king among level five demon beasts. At its peak, its combat power was almost comparable to that of a human in the Emperor Martial Realm. Even though it is now severely injured, it should not have much of a problem to completely crush humans below the Emperor Martial Realm."

Fortunately, it is usually dormant. When passing through this Heavenly Demon Valley, as long as one does not use spiritual power and does not make too much noise, one can pass through without hindrance and will not wake it up.

However, if it is accidentally awakened, its overwhelming ferocity will ensure that any human who rashly enters the Heavenly Demon Valley will meet a gruesome end.

Ren Pingsheng remembered that once, a top expert whose cultivation had reached the ninth level of the King Martial Realm, just one step away from the Emperor Martial Realm, traveled here. Upon hearing about this silver eagle, instead of avoiding its sharp edge, he deliberately woke it up, intending to tame it.

As a result, it was torn to shreds by an enraged silver eagle, and now the grass on the grave has grown dozens of times over...

From then on, no one who passed through the Heavenly Demon Valley dared to release the slightest bit of spiritual power, fearing that they might awaken the silver eagle and repeat the mistake of that top expert.

Ren Pingsheng paused, his tone becoming increasingly serious: "This is the only way to the Northern Border, and also the only dangerous place along the way. Just in case, I'll go scout ahead first."

Qin Changye stopped him, saying, "I'll go."

Then, without giving Ren Pingsheng a chance to reply, Qin Changye had already entered the pitch-black fog ahead.

There is a huge cave on the west side of Tianyao Valley.

A continuous stream of black mist poured out from this enormous cave, shrouding the entire valley in suffocating darkness.

Deep within the cave, a chilling, thunderous snoring sound echoed continuously, emanating from the silver eagle, known as the Demon King.

At this moment, two people were already standing outside the cave, staring at each other with unfriendly expressions.

What are you doing here?

As the Empress's trusted bodyguard, the man in black never wastes words; he prefers to solve problems with his long sword rather than with his mouth.

However, the gray-clad man in front of him was no weaker than him in any way. If they really fought, he would be evenly matched at best.

Moreover, this place is right outside the cave where the silver eagle sleeps. If you use your spiritual power during a fight, you might wake the silver eagle.

That's why he unusually asked a question.

"I was ordered by my master to come here and kill someone."

The gray-clad man, as the strongest assassin planted by the barbarian kingdom in the northern border of the Great Zhou, also disliked idle talk, but at this moment he had no choice but to reply.

The man in black frowned. "What a coincidence. I was also ordered by my master to come here to kill someone. I'm here to kill Qin Changye. Who are you here to kill?"

The man in gray's eyes lit up: "What a coincidence, I also want to kill Qin Changye."

The two exchanged a glance, instantly relaxing their guard and finding each other more agreeable.

The enemy of the enemy is the friend.

Both men were willing to sacrifice their own loyal followers in order to kill Qin Changye, and they couldn't help but feel a sense of shared suffering.

"Brother, since we're all going to die anyway, let's talk. Who's your backer?"

Before Qin Changye even arrived, the man in black started a conversation.

The man in gray hesitated for a moment, intending to tell the truth that his master was the Barbarian Emperor. However, he then remembered the message that His Majesty the Barbarian Emperor had entrusted to the Grand Eunuch before his departure, and immediately replied, "Brother, since you have asked so sincerely, I will not pretend anymore and will lay my cards on the table. In fact, my master is Her Majesty the Empress of our Great Zhou Dynasty."

The man in black was stunned for a moment. "You were sent by Her Majesty the Empress, then who sent me?"

The man in gray didn't notice the change in the man in black's expression and continued speaking to himself: "You're probably very surprised that the Empress of the Great Zhou Dynasty would kill the newly appointed General of the Northern Border of the Great Zhou Dynasty, aren't you? Well then, let me explain."

The man in gray became more and more excited as he spoke, as if he wanted to say all the nonsense he hadn't said in years before he died: "Our Great Zhou Dynasty's new General Qin Changye in the northern border is too sharp and has too much power behind him. He has already affected the authority of our Empress. So our Empress wants to kill him... In our Empress's words, this is called 'to pacify the internal before fighting the external.'"

After saying this, the gray-clad man turned his gaze to the black-clad man and asked, "By the way, tell me, who is your master? And why did you want to kill Qin Changye?"

The man in black was speechless for a moment. "You've already said all my lines. What else do you want me to say?"

However, remembering the Empress's special instructions to him before she sent him here, he said, "Brother, since you've asked so sincerely, I won't pretend anymore. I'll lay my cards on the table. I am a barbarian, and my master is His Majesty the Barbarian Emperor. This Qin Changye almost killed our Barbarian Crown Prince. Our Barbarian Emperor hates him to the bone and wants me to kill him at all costs."

The man in gray was stunned and puzzled. "You were sent by His Majesty the Barbarian Emperor, then who sent me?"

The next moment, the two who were just good friends suddenly distanced themselves, and the murderous intent in their eyes rose sharply as they looked at each other.

The man in gray was the first to recover, and he lowered his voice to question, "You say you were sent by the Barbarian Emperor? I think you were sent by the Empress. The Empress sent you to impersonate the Barbarian Emperor and frame me."

The man in black sneered: "Aren't you also sent by the Barbarian Emperor, yet you call yourself the Empress's person? You're the one who framed him."

If you don't see eye to eye, even half a sentence is too much.

To protect their respective masters' secrets, the two immediately engaged in battle.

Of course, this is the Heavenly Demon Valley, and right at the entrance of that silver eagle's cave, even the slightest exertion of spiritual power could awaken it.

Therefore, the two powerful experts at the King Martial Realm chose to abandon their spiritual power and engage in an unprecedented close-quarters combat.

The man in gray extended a finger and plunged it straight into the man in black's eye socket, quick and ruthless, with sand still hidden under his fingernail.

The man in black abruptly turned his head to avoid a fatal blow, but a bloody scratch appeared at the corner of his eye. He then retaliated with a groin-striking palm strike, his palm precisely striking between the legs of the man in gray.

The man in gray winced in pain, squeezed his legs together, and jumped back three steps, cursing in a distorted voice, "You slapped my genitals, you have no sportsmanship!"

The man in black pressed his advantage, coldly retorting, "You talk about martial ethics, but would you gouge out my eye sockets?"

As they fought, the two were rolling around on the ground, using their hands and feet to pinch, grab, twist, and bite...

"You're a real beast!" The man in black was furious, his manhood almost broken off by the man in gray.

"You're not human either!" The gray-clad man, his face and body covered in bloody scratches, retorted sharply.

Then, suddenly, the sound of footsteps came.

The two of them stopped what they were doing at the same time, stared intently, and shouted simultaneously, "Qin Changye, you've finally arrived!"

Qin Changye looked down at the two men wrestling on the ground, his brows furrowing slightly.

The man in gray was still pinching the man in black's eye sockets, and the man in black was still clutching the man in gray's penis...

In fact, Qin Changye had sensed two unfamiliar auras near the cave as he approached.

I thought it would be a meticulously planned ambush, but what I saw was this utterly absurd scene.

The next moment, the two of them released their grip at the same time, sprang up from the ground, and then pounced on Qin Changye.

The two who were fighting to the death just moments ago are now working together in perfect harmony, like a pair of inseparable partners.

The man in gray formed his five fingers into claws and aimed straight for Qin Changye's eye socket.

The man in black slapped out his palm, aiming for Qin Changye's genitals.
