Whoosh! Suddenly, the black and white swords floating around swept out and entangled in mid-air. The black and white sword energy intertwined to form a yin and yang pattern.
"Liangyi Sword Formation, completed!"
The corners of Mu Feng's mouth curled up slightly, and he waved his sleeves again, and seven spiritual swords of different colors came out across the sky and turned into a rainbow, streaking through the void.
"The Seven Rainbow Sword Formation is completed!"
Mu Feng murmured softly and pointed the sword finger of his right hand in the air. He saw the Seven Rainbow Sword Formation flying across the sky to catch up with the Liang Yi Sword Formation. The two sword formations were combined together to form a more complex combined sword formation.
The Liangyi Sword Formation is an advanced sword formation of the Tai Chi Sword Formation, and is a genuine king-level sword formation.
The so-called Yi has Tai Chi, the two Yis are born, the two Yis are the four images, and the four images are the Bagua! The Liangyi sword formation seems to only consist of black and white swords, but the changes in the sword formation are far greater than the Tai Chi sword formation.
The Seven Rainbow Sword Formation is a king-level sword formation that is not weaker than the Liangyi Sword Formation in Mu Feng's memory.
Mu Feng has observed the characteristics of the nine-handled spiritual sword of the Nine Swords Martial King, and found that it is the most suitable for these two sword formations.
Moreover, the Liangyi Sword Formation is mainly for defense, and the Seven Rainbow Sword Formation is for attack.
One attack and one defense complement each other! Roar! Chi Sha suddenly roared into the sky, carrying a billowing evil energy, and instantly enveloped the two sword formations.
At the moment when Chi Sha and the two sword formations merged into one, the originally illusory body gradually became clear, and the blood-colored scales on his body were lifelike and shimmering with scarlet luster.
With the help of Liang Yi and the Seven Rainbow Sword Formation, Chi Sha's strength skyrocketed, and he was even able to fight a fourth-level Martial King.
If Chi Sha's strength reaches a higher level, there will be few middle-level Martial Kings that can be its opponents.
"Huh?
It seems that Senior Sister Xiyu is about to make a breakthrough!"
If Mu Feng realized something, his eyes fell on the beautiful girl sitting cross-legged on the futon not far away.
At this moment, Gu Xiyu's forehead was dripping with beads of sweat, her cheeks were flushed, and the aura in her body was getting stronger and stronger.
At the same time, an invisible ripple washed out, continuously gushing out from Xiyu's body in all directions.
This ripple contains a sharp aura, which makes people feel as if a sharp sword is piercing them, making people shudder.
"Sword Intent! It seems that Senior Sister Xiyu has completely understood the Sword Intent, and has reached the realm of the King of Martial Arts with the sword's artistic conception."
Mu Feng murmured to himself.
The commotion in the tomb became louder and louder, and Concubine Feng Luo, Xing Xiuqi and Ji Mingxu, who had been in meditation, woke up one after another.
"Junior Sister Xiyu is about to break through!"
Ji Mingxu and Xing Xiuqi quickly took Concubine Feng Luo to Mu Feng's side. They saw something strange about Gu Xiyu at a glance.
Mu Feng nodded, led the three of them back into the passage, held out the formation flag in his hand, and immediately activated the three spiritual formations arranged in the tomb.
King Wu's breakthrough was far more dynamic than in the Life Sea Realm, so Mu Feng was naturally well prepared.
Bang bang bang! Suddenly, Gu Xiyu, who was sitting in the tomb, erupted with a terrifying aura, and sword aura swept away in all directions like a storm.
However, the moment the sword energy escaped to the corners of the tomb, layers of brilliant barriers appeared, blocking all the sword energy.
The sword energy is getting more and more dense, and the barriers around the tomb are shaking violently, but they are extremely tough and unmoving.
Concubine Feng Luo, Xing Xiuqi and Ji Mingxu's expressions changed greatly, and they looked at the dense sword energy in the spiritual formation with fear.
These sword energies are so terrifying that if they were in them, they would be torn to pieces immediately, leaving no trace behind.
After an unknown amount of time, the ripples of sword energy in the tomb chamber poured into Gu Xiyu's body like the sea containing hundreds of rivers.
At this moment, Gu Xiyu slowly opened her eyes. Her beautiful eyes shone with a sharp edge that was hard to look into.
"Senior Sister Xiyu! Congratulations on your successful breakthrough to the realm of King Wu!"
Mu Feng stepped forward, smiled and congratulated.
Gu Xiyu's beautiful eyes narrowed into a crescent shape, and a smile that could not be concealed appeared on her beautiful face, and she said: "Junior Brother Mu Feng is so polite! I can break through so quickly, and I have to thank you!"
"Sister Xiyu, you're welcome!"
Mu Feng waved his hand and said: "The spiritual veins here are extremely extraordinary! Senior Sister Xiyu has just broken through, and she still needs to consolidate it!"
Gu Xiyu nodded, her beautiful eyes flickered, and fell on Mu Feng, saying: "Junior Brother Mu Feng! You should be able to break through to the Martial King realm at any time, why haven't you been able to break through?"
Concubine Feng Luo, Xing Xiuqi and Ji Mingxu also looked at Mu Feng with doubts in their eyes.
"I'm afraid that the breakthrough movement will be too great and the entire Tomb of King Wu will not be able to bear it!"
Mu Feng said seriously.
Gu Xiyu and Concubine Feng Luo were stunned, but they quickly came to their senses.
Mu Feng is too powerful, and he has realized the four artistic conceptions. Once he breaks through the realm of King Wu, the power of the four artistic conceptions will transform at the same time, and his momentum will definitely be much greater than that of Gu Xiyuhao.
"I plan to wait until you leave King Wu's tomb before starting to break through! Otherwise, I won't be at ease!"
Mu Feng looked at the four of them and continued: "Next, you continue to practice here, I need to go to the underground tomb! After practicing, you will leave the tomb of King Wu."
Gu Xiyu and Concubine Feng Luo looked at each other in confusion when they heard this. Under Mu Feng's explanation, they also learned that the murals on both sides of the underground tomb passage contained the will of the sword of the Nine Swords Martial King.
However, the will of the sword in the mural was too powerful. Only Mu Feng could resist the attack of the will of the sword, so Mu Feng did not let the four of them comprehend it together.
Gu Xiyu and Concubine Feng Luo also understood Mu Feng's painstaking efforts and did not try to persuade him to stay.
Mu Feng gave a few more instructions, then re-disguised the four of them, and also changed their clothes before leaving the tomb.
Of course, before leaving, Mu Feng also put away the evil soul, the big soul and the second soul.
Gu Xiyu has broken through to the realm of King Wu, and no one in the entire Tomb of King Wu can threaten her.
After leaving the tomb, Mu Feng followed the passage and headed towards the exit of King Wu's tomb.
Along the way, he met many casual cultivators.
These casual cultivators did not dare to enter the tomb, but they were unwilling to leave like this, so they searched everywhere else in King Wu's tomb.
Of course, Mu Feng also encountered many scuffles, all caused by robbing treasures.
However, when Mu Feng passed by, these casual cultivators recognized Mu Feng one after another. They were all so frightened that their legs became weak and they temporarily stopped fighting.
After Mu Feng left, the melee broke out again, with shouts of death, noises, etc. becoming one.
Soon, Mu Feng reappeared in the underground tomb passage.
Mu Feng walked to the front of the tomb passage and his eyes fell on the first mural.
After learning that there was something strange about the death of King Nine Swordsman, Mu Feng knew that he might be able to find some clues from these murals.
Along the way, Mu Feng browsed the contents of the mural again, this time he looked at it very carefully.
This time, he discovered something unusual in the mural.
Among all the murals, only the protagonist in the first mural is from the front, while the protagonists in the other murals are all from the back.
Mu Feng discovered that there was a very blurry black spot on the blurry face of the protagonist in the first mural, which was located exactly between the eyebrows.
At first, Mu Feng thought it was a mole between the eyebrows of the Nine Swords Martial King, so he didn't pay much attention to it.
But when he saw the last mural, he no longer thought so.
Because, opposite the protagonist of the last mural, the figure covered in golden light has a dark spot between the eyebrows on his blurred face.
Moreover, the black spots of the two are exactly the same, both in location and shape.
Mu Feng had a feeling that there was definitely something wrong with the black spot between his eyebrows.
