"Forbidden?" Xu Yichen had doubts in his mind, at this moment, he had a feeling that he hated less when he used the book, and he knew that he would read a hundred volumes like Zhou Ping, so it wouldn't be like this.

"This forbidden art, it can't be that sword!" In his mind, the Yaksha King exclaimed.

Xu Yichen immediately asked, "What is this?" ”

After all, the Yaksha King signed a contract with Xu Yichen, whether it was limited by the strength of the formation or driven by interests, he did not have any reservations. After all, the stronger Xu Yichen is, the more benefits he will get from Xu Yichen.

"Forbidden art is a special spirit technique that relies on spirit soldiers, but not every spirit soldier has it, of course, the yuan soldiers above the spirit soldiers may also hide forbidden arts, and they must reach the realm of heart with the spirit soldiers to comprehend the forbidden arts in the spirit soldiers."

"The value of a spirit soldier with forbidden art will naturally rise to a higher level."

Hearing the Yaksha King's narration, Xu Yichen also remembered the Yanlong Slash of the Yanlong Sword and the Heaven and Earth Destroying Array of the Seven Killing Arrays.

"There's also a forbidden spell hidden in the Dark Magic Sword! The Black Magic Sword is a spirit weapon, which is also the art of spirit forbidden. The reason why it is called a forbidden technique is that it is the same as a forbidden drug, once it is cast, although it is infinitely powerful, it will cause great damage to the treasure. The Yaksha King continued.

Xu Yichen nodded: "Well, I understand this, the seventh formation of the Seven Killing Array Destroys the Heaven and the Earth, and the Yanlong slashes the seventh to kill me as the Yanlong, and after it is cast, it is infinitely powerful, and it has helped me survive two crises, but unfortunately the Seven Killing Array and the Yanlong Sword have been completely destroyed because of this." ”

"Haha", the Yaksha King laughed wildly when he heard Xu Yichen's words: "That's because you are too weak to let those two treasures completely communicate with your mind, and you use the power of the treasure to cast the forbidden art, not because of its willingness, the power of the forbidden art it casts is not only limited, but also extremely harmful to the treasure itself." ”

Xu Yichen suddenly realized that the Yanlong Sword only recognized him, and his comprehension of the Yanlong Slash was also because of the trace of the spirit rhino sword hidden inside. Not to mention, the Seven Killing Array has been used by the masters to wear out its spirituality and become a formation tool, and it has no heart to heart with Xu Yichen.

"If you reach a heart-to-heart connection, what will happen if you use this forbidden technique?" Xu Yichen asked.

The Yaksha King said, "It depends on how much power you can wield, if you can cast the full power of this sword in one forbidden spell, this sword will fall dormant due to the emptiness of power, but it will not be broken like the Flame Dragon Sword." ”

"I see!" Xu Yichen understood, and let out a long "oh".

"However, treasures have spirituality and arrogance, and the more powerful the treasure, the stronger the arrogance, and how difficult it is to make it communicate with a mortal." The Yaksha King smiled disdainfully, "Do you really think that this Dark Sword is in touch with you because of your strength?" ”

Xu Yichen was puzzled by the words of the Yaksha King.

"Why is that?"

The Yaksha King was silent at this time.

Xu Yichen shrugged helplessly, and didn't care about him, he burst out with cathode spiritual power, laying down a hundred refining arrays, and strengthening the Black Demon Sword. The Black Demon Sword accepted the power of the Hundred Refining Array without resistance, and sucked the breathless spirit wildly.

In addition to refining the army, Xu Yichen also continued to hurry, and at the same time asked the Yaksha King, "You seem to know this sword?" ”

The Yaksha King was silent for a moment before he spoke, "You just asked me why, and I will tell you together that this sword is made of my teeth and scales, which drip into my flesh and blood. ”

"What?" Xu Yichen stood in place all of a sudden, and even the Hundred Refining Array stopped in shock.

"Hmph, what a fuss, it's just a half-finished product in the world!" The Yaksha King looked at Xu Yichen's surprised appearance and looked proud: "Back then, I used my teeth and scales to create eighteen kinds of weapons, and gave them the name: Night Soul"

"Among them, the Night Soul Shield, the Night Soul Gun, and the Night Soul Sword are in my hands."

Xu Yichen remembered that when the Black Devil Sword recognized the master, the black mist that erupted was very similar to the black mist emitted from his body when he met the Yaksha King in the dark forest that day. Moreover, the Yaksha King is indeed armed with a spear, a great sword, and a giant shield.

"What's the matter with the semi-finished product?" Xu Yichen continued to ask.

"When I first created these eighteen weapons, there were some failures, and this black magic sword in your hand is the failure to build the Night Soul Sword, I never thought that it would end up in the human world."

"Look at your appearance, this kind of goods is still a treasure in this human world, and the human world is indeed the most barren realm of the six realms."

Xu Yichen coughed lightly, and he couldn't deny the words of the Yaksha King.

"Hehe...... Xu Yichen suddenly smiled, and then he said to the Yaksha King: "Then can you turn the black magic sword in my hand into a finished product?" ”

"I'll talk about this after learning the Spirit Gathering Array!" The Yaksha King was dissatisfied and said: "There are not tens of millions of people who want to sign a contract with this king for hundreds of millions of years, but there are only two or three people who are favored by this king, and they are all kings of thousands of miles!" ”

"I didn't expect to sign a contract with a formation master like you who can't even gather the spirit array this time!"

Xu Yichen's mouth was deflated, and he said stupidly: "Hey, the Spirit Gathering Array, the Spirit Gathering Array, where are you......"

While talking, the Hundred Refining Array had been completed, the Black Magic Sword had been strengthened, and its strength was not much different from that of the Heavenly Rank Spirit Soldier. If the forbidden technique is added, its actual strength is a few points stronger than that of a heaven-level spirit soldier.

Four hours later, a gray array appeared in front of Xu Yichen to block his way. This Absolute Array is not on the stone slab map of the Forbidden Land of Eternity, it seems that it should have been imposed by the people of the Qilin Gate, and there are several large characters built by the formation pattern floating on it.

"Those who step in, don't talk about killing - Ouyang Qi!"

"Who is Ouyang Qi?" Xu Yichen muttered, then ignored the warning and immediately unraveled the magic circle. Xu Yichen learned from the map research that not only could he go to the Zun Domain, but there was also a path to quickly reach the maze at the end of the competition.

Although the person who cast this array is a gray formation, it is at least a first-order spirit venerable, and Xu Yichen can't break it with the formation, so he can only use the method of dissolving the formation, which will attach the cathode spiritual power, and then carefully perceive its lines.

Fortunately, the person who established the formation here didn't know much about the formation technique, this formation technique was very ordinary, although Xu Yichen spent a lot of time, he still succeeded in temporarily breaking a hole in this formation.

At this time, in a room in the Qilin Palace, eight white-bearded old men were standing on the ground with their eyes closed.

"The door master's formation has been lifted!" One of the old men suddenly opened his eyes and shouted in amazement. The other seven people were also surprised, and one of them had a serious face: "Hurry up and track down this person's information, there is this Venerable Domain there, and the secrets it hides must not be known to outsiders." ”

The eight of them formed the Dharma Seal together, but after a while, they all turned pale and panicked: "I can't track this person's breath!" ”

"Could it be that there is a person who transcends the sect major, or is it a formation master who has broken in? Xuzhou doesn't have this person? ”

An old man got up and said as if facing a great enemy: "The seven of you quickly go to the scene to check, and I will go and tell the door master!" ”

At this moment, Xu Yichen didn't know what was going on. Walking briskly, he came to the entrance to the Zun Domain, marked by the stone map, which looked no different from the surrounding forest.

Xu Yichen knew that it was because there was a hidden mechanism in front of him, which was a formation with a green formation.

Not a single grass or tree here can be moved, and not an inch of land can be trampled on. Once you step on the wrong step, you will immediately be strangled by the power of the formation.

"Good thing I have a map!" Xu Yichen smiled slightly.

While recalling the information in his mind, Xu Yichen found the towering tree, a blood-red jade under the tree, a tip of the red jade pointed, Xu Yichen found a three-foot place and began to cast the formation.

Xu Yichen, who cultivated as a fifth-order spirit master, relied on the Breathless Spirit, his strength was comparable to that of an eighth-order spirit master, and with the white formation pattern, it was enough to open this door.

The white formation pattern shone with white light, and a door constructed of green formation patterns appeared in front of Xu Yichen's eyes. Continuing to pour in the cathode spiritual power, the door slowly opened.

"Whew~" A majestic suction burst out from inside the door, Xu Yichen couldn't resist, or he didn't even have time to react, he was directly sucked in!

Entering the door is like being in another world. In front of me was a stone tunnel, with no end in sight, and the surrounding walls shone with an eerie glow. If you look closely, there are thousands of formations depicted, and these formations seem to have some kind of connection, and the power is integrated, Xu Yichen feels an incomparable pressure.

Xu Yichen turned into Xingchen armor, and refined a little bit of the power of the shadow of Xuanwu to bless the armor, and the blue armor turned black in an instant, its strength was greatly improved, and it was more domineering.

He took out four seven-rank pills from the Qiankun box, which Xu Yichen had refined during the preparation period. Xu Yichen is nominally the fiancé of the second miss of the Murong family, and the shopkeeper of the Tianhua medicine store is the second lady's person, so he will not lack medicinal materials.

These four seven-rank pills are the Tiger Power Pill, the Wind Spirit Pill, the Spirit Domain Powder, and the Strengthening Muscle Pill, which just improve Xu Yichen's strength, speed, spiritual power refining, and physical strength. At the same time, Xu Yichen wrapped the seven-grade forbidden medicine and the Pulse Protection Pill with a formation pattern and placed them on both sides of his mouth. In the event of an emergency, it can unlock the formation and devour the forbidden medicine to increase its cultivation.

The black magic sword was already in the palm of his hand, the black mist lingered, Xu Yichen was in touch with his heart, and he could feel that it was trembling.

After getting ready, Xu Yichen took a deep breath and walked forward. Inside the tunnel, there was silence, only Xu Yichen's own footsteps echoed.

"Tick" sound.

Xu Yichen turned around in surprise, only to see a drop of water falling from the top of the tunnel. Xu Yichen's eyes trembled suddenly, and the drop of water dripped on the ground, blending into the underground formation, one into two, two into four...... The entire tunnel formation was triggered, and there was a piercing humming sound, and in an instant, that drop of water turned into a monstrous wave.

This huge wave is not an ordinary water wave, but a wave of formations! The formation pattern actually merged with the water droplet, and the overwhelming momentum rolled over, cracking the tunnel and disturbing the void.
