A blood-colored streamer appeared out of thin air, instantly piercing the tiger in front of Liu Yuan, and the "Liu Yuan's son" who was holding Liu Yuan on the side showed an angry expression of gritting teeth.

He pulled out a dagger from his waist and began to stab Liu Yuan frantically.

"Son, what are you doing!"

Liu Yuan hurriedly dodged the dagger's stabbing blow, but this body was already old, not to mention the speed of a young man's "son", and the dagger still left a deep wound on Liu Yuan's right arm.

Suddenly, a red streamer appeared between Liu Yuan and the murderer, it was the one that killed the tiger just now, somehow, it may have consumed too much energy to kill the tiger, causing it to sway now, and its speed has slowed down a lot.

Liu Yuan's eyes were gradually able to catch up with this red streamer, it was a knife with a very narrow blade, it looked very sharp, there seemed to be two words written on the knife body, Liu Yuan opened his eyes wide to see which two words, and slowly read them out in his mouth.

Naruto...... Hong!"

The word Ming Hong instantly exploded in Liu Yuan's mind, and Liu Yuan thought about it as if he was magical, and said it repeatedly in his mouth.

"Minghong, Minghong, Minghong! By the way, Ming Hong is my sword, my sword, but why do I have a sword? ”

"By the way, I'm a cadet of the Human Federation's Tinder Program, I'm a warrior! Who is my enemy? Be...... It's the fog beast, it's the group of traitors of the Illuminati. ”

"I remembered, I remembered it all."

Liu Yuan's middle-aged body regained its youth in an instant, and a powerful force appeared on his body again, and the sword flying in front of him Ming Hong also changed from the sick appearance just now to a vigorous tiger.

His right hand held Ming Hong's hilt again, and his left hand stroked the blood-red blade, and muttered, "Ming Hong, I owe you my life." ”

Ming Hong in his hand responded to Liu Yuan with a crisp knife sound, as if to say that you are not welcome.

Liu Yuan looked up at the front, and the Ming Hong in his hand was raised, and he slashed it down, and the scenery in front of Liu Yuan's eyes was like a mirror, and it was slashed to the ground by Liu Yuan's slash.

Liu Yuan's surroundings fell into darkness, and a little light appeared in front of him, and following this light, Liu Yuan walked out of this world.

In the third sword mound, the colorful jelly-like object that had wrapped Liu Yuan's head before was all absorbed into Liu Yuan's brain.

After opening his eyes, Liu Yuan felt refreshed, he had never been so energetic, as if he had a good night's sleep.

"Whoever wields a knife must be decisive in his killings and deadly in his moves. What is a knife user? Those who are determined in their minds are also! ”

Liu Yuan only then understood the meaning and completion conditions of the third layer, that is, a qualified swordsman, having Xiaocheng's sword posture is not enough to make him a swordsman, and the most important thing is needed, that is, the kind of swordsman ambition that can carry the sword momentum.

The passage to the fourth floor was opened, and Liu Yuan confidently stepped in, and after a short period of darkness, the whole picture of the entire fourth layer appeared in front of Liu Yuan's eyes.

A small pond of about three square meters appeared in the center of the fourth floor of the Sword Tomb, and directly behind the pool, a humanoid sculpture of Liu Yuan's unusually familiar one came to life again.

"A swordsman needs to have enough strength to kill whoever he wants to kill! Victory, death! ”

After saying this, the sculpture turned into rubble and scattered all over the ground.

Looking at the surrounding environment, Liu Yuan found that the fourth floor was a little different, the door to the fifth floor was directly revealed, and there were two handles on the door.

Liu Yuan immediately stepped forward, holding the doorknob with his right hand and began to open the door to the fifth floor of the Sword Tomb, but to Liu Yuan's surprise, the door did not move at all.

Instead, he held the entire doorknob with both hands, and pulled the entire door with all his strength, but he still didn't move, you must know that Liu Yuan's real strength has reached the level of a middle-level warrior.

Even the mid-level Battle Hero level can't shake this gate, which door may need the Battle King level to open this gate.

Liu Yuan frowned, thinking to himself.

"The Kunlun Secret Realm has only been open for half a year, and it is estimated that it will take me about half a month in the third layer of the Sword Shrine, and the last half a month is to prepare to return to the Dragon Tengxing through the Boundary Gate, and I only have five months to cultivate in total."

"It's not impossible, even if I have the assistance of the sentient beings in the system, it is impossible to reach the strength of the Battle King level in five months, the difference between the War King and the War Hero can be said to be a world of difference, and it is a huge watershed."

Shaking his head, Liu Yuan thought that it was impossible for Sword Shrine to use an impossible task as the test content of the fourth layer, so Liu Yuan began to look for other things around him.

But after a few minutes, Liu Yuan found that there was nothing else on the fourth floor of the entire Sword Shrine, except for this doorknob and this pond.

In the end, Liu Yuan focused his gaze on the pond in the center of the fourth layer of the entire Sword Tomb.

There were no other creatures in the whole pond that was cool to the bottom, and the bottom of the pond looked like an ordinary stone wall at a glance, and Liu Yuan immediately stretched out his left hand to touch the pond water.

At this moment, Liu Yuan felt the powerful energy coming from the index finger of his left hand, which quickly passed through Liu Yuan's index finger into his body, and was immediately absorbed and transformed.

It can be said that the pond in front of him is a large area of energy liquid that can be absorbed infinitely, with this, and with the assistance of the system sentient beings, Liu Yuan feels that there is hope for completing this task.

Immediately, he directly sank his whole body into the entire pond, and a large amount of energy rushed into Liu Yuan's body, but so much energy did not make Liu Yuan feel a sense of fullness.

Although the genetic energy flowing between the tendons and acupoints has expanded several times, it has not broken through the acupuncture points of the tendons and veins.

These newly added energies seemed to be catalysts, and none of the attributes were smoothly and completely dissolved into Liu Yuan's own genetic energy.

Liu Yuan's cultivation speed soared instantly, and then he entered the realm of sentient beings, and the time he had spent cultivating in the third layer before had almost replenished Liu Yuan's cultivation time in the sentient realm.

In the realm of living beings, Liu Yuan's cultivation speed at this time can be called terrifying, and the speed at which he runs the Ten Thousand Worlds Furnace Evolution Technique can be said to be the fastest ever, and he can still maintain it all the time.

Liu Yuan was cultivating frantically in the fourth layer of the Sword Shrine, but the Kunlun Secret Realm ushered in a big change this time.

The Kunlun Secret Realm has only been open for about half a month at this time, and according to past experience, humans and fog beasts will not encounter and contact at this time.

But this time the Kunlun Secret Realm didn't know what was going on, the Fog Realm side was stimulated, and from the very beginning, it rushed towards the area of the human side, and did not explore the area of its own side at all.

So in just half a month, most of the human beings have encountered the fog beast, about fifty students have died at the hands of the fog beast, and many more human students have killed the fog beast they encountered.

There are only about 300 of the 500 fog beasts released by the fog realm now, and these 300 fog beasts are still hunting humans in the area where the human side is active.

It seems that this time the Kunlun Secret Realm Fog Beast side no longer let these young fog beasts experience and explore the Kunlun Secret Realm, but only perform one task, that is, hunt and kill the genius students of the human side.

The Human Federation and the Mist Beasts of the Mist Realm were still in a relatively balanced state, because of the containment of high-level strength, a super-large-scale all-out war did not break out.

The real reason why the human side was able to rely on the leadership of King Zhennan so easily to let the Fog Realm and the Human Federation sign a temporarily stable treaty was only known to the Titled God of War and a few top War Venerables.

Dragon Tengxing, deep in the fog realm, above an ocean covered with ice, the top of a huge black triangle protrudes from the ice for about twenty meters, and how much of it is hidden in the ocean is still unknown.

The top of the black pyramid was constantly flickering with bursts of black light, and all the fog beasts around it, which the Human Federation called Pandora, knelt down here.

Suddenly, the black light of this black pyramid began to flicker violently, and there were dozens of Pandora-level fog beasts kneeling behind them, and hundreds of Feilian-level fog beasts were instantly enveloped by the black light.

The moment these ten fog beasts were covered by the black light contact, they fell straight to the ground, and their bodies began to twitch non-stop, and these black lights frantically drilled into the bodies of these fog beasts.

The other hundreds of Feilian-level fog beasts looked at the ten mist beasts on the ground that were constantly twitching, and their eyes showed extremely envious looks.

Soon, three minutes later, the ten Feilian-level mist beasts on this ground were all wrapped in a layer of purple-black cocoons on the outside of their bodies.

The surrounding fog beasts buried their heads even lower, and after more than ten minutes, the purple-black cocoons on the ground began to crack, but there were only four broken cocoons, and the remaining six were silent.

Soon, half an hour later, the fog beasts inside the four purple-black insect cocoons broke out of their cocoons, and the four fog beasts moved their bodies that had changed greatly and bowed down to the black pyramid again.

The location of these four fog beasts was also different from before, as if they were already on an equal footing with the dozens of Pandora-level fog beasts, and their aura was also comparable.

The remaining six purple-black cocoons melted into a puddle of black slime at a speed visible to the naked eye, and of course, the Feilian-level mist beast that had been wrapped in these cocoons before died.

At the end of the ceremony, a group of fog beasts kneeling down continued to speak a word of fog in their mouths, which roughly meant.

"Long live the God of Light! Long live the god of light! Long live the god of light! ”

Soon the black pyramid spire sank to the bottom of the sea again, and a group of fog beasts also got up, and dozens of Pandora-level fog beasts expressed their congratulations to the four newly promoted fog beasts.

Immediately, the Pandora Mist Beast led by him said a Fog Realm language to a large group of Mist Beasts, and the meaning expressed after summing it up was:

"It's time for humanity to go extinct!"

Three months later, in the Kunlun Secret Realm, the geniuses on the side of the Human Federation have now made great progress after about three months of training.

However, in the face of the unreasonable brainless attack of the fog beast, these students on the human side also suffered huge losses, and now there are probably only more than eighty students left alive in the entire Kunlun Secret Realm, and these eighty students can be said to be the best among all the students.

On the fourth layer of the Sword Shrine, the pool of water that was full before was already running out with Liu Yuan's cultivation, and in three months, Liu Yuan had already exhausted the cultivation time of the sentient beings.

He could only pinch the time every day, and once the system was reset, Liu Yuan would be able to enter the realm of sentient beings for three hours.

And these three months of cultivation have also made Liu Yuan improve greatly, Liu Yuan's real strength is now at the peak battle hero level, and the surface strength is at the peak battle general level.

Just one foot at the door, Liu Yuan had already vaguely touched the threshold of the combat power of the Battle King level, and there was not much magical water left in the pond, Liu Yuan muttered in his heart: "Just today!" ”
