After many experiments, Yun Yifei finally refined the Four Towers Flame Wall Array, spending most of the time on the inscription of the combined runes. Although it took some twists and turns to refine the array flag array plate, he did not take much time to understand the refining method.

Yun Yifei arranged the formation and activated several magic tricks. In an instant, a large area of ​​hot energy spread. After observing the formation for a long time, Yun Yifei thought for a moment and plunged into it.

“Huhhhh…”

As soon as Yun Yifei entered the range of the formation, he saw a large amount of flames rushing towards him. After being mentally prepared, he flew his hands and fingers, and the majestic spiritual power condensed into a huge water dragon and greeted the flame energy.

"Sizzy..."

The flame energy expanded rapidly, and the time was not long, so the water dragon was shrouded in it. Yun Yifei's spiritual consciousness was difficult to penetrate it, and he could not see the scene inside. He had to use the Breaking Pupil. He saw that the water dragon was quickly consuming energy under the burning of the flame energy. Although the water dragon could also offset some of the flame, compared with the boundless flame, the losses were basically negligible.

The flame energy in the formation was still growing rapidly. At this time, the places where they entered their eyes were full of rich flames. Yun Yifei was submerged in it in an instant. He did not sacrifice a defensive magic weapon, and he felt the energy of the flame with the strength of his body that he could resist the attack of the magic weapon.

Yun Yifei's clothes turned into ashes for a moment. Faced with the burning of the flames, he was also very surprised and surprised by the power of the flames. Even with his strong body, he had not lasted for long in this formation. He thought about it and half of the gourd fan artifact was sacrificed, protecting it in front of him, and a solid yellow shield was released from the magic weapon, covering it, so that the pressure was greatly reduced.

"This formation is indeed well-known. If some rare fire-attribute materials are used to refine the array flag, its power can be increased a little more." Yun Yifei sighed in his heart and was somewhat expectant.

Suddenly, the dragon and snake flew under Yun Yifei's feet and shot in one direction.

Along the way, the fire energy spreading everywhere was as if he had discovered a target, gathered towards Yun Yifei, which greatly affected him and doubled the pressure. Then, he raised his hand and stimulated several water-attributed talismans, which were ignited forward.

"Bang, bang, bang..."

The water-attributed spells did not last long in this world of flames, and then they collapsed one after another, but they also consumed part of the flames. Yun Yifei seized this opportunity, rushed out, and shot forward.

Yun Yifei clearly felt that as he penetrated into the formation, the flame energy spread became stronger, and the flame gap consumed by the water-attributed talisman was also filled in an instant, which had a great impact on it.

"The dragon penetrates the clouds"

"The dragon goes out to the sea"

"Two Dragons Draw Water"

Yun Yifei walked along the dragon and snake, waved his fists repeatedly, and three styles of boxing were used in succession. Four powerful dragons roared out, stirring the sea of ​​fire, opening up a narrow road for Yun Yifei.

“Huhhhh…”

The flames surged and fought against the powerful dragon. Yun Yifei took the opportunity to rush straight forward without delay.

"Bang"

"Bang"

"Bang bang"

Four muffled sounds sounded almost at the same time, and the four powerful dragons were finally overwhelmed and collapsed at the same time. Without the obstacle of the powerful dragon, the flame energy came over, making the magic weapon Yun Yifei sacrificed was also trembling.

"So strong", Yun Yifei was surprised and happy. The stronger the power of this formation, the happier he was. After all,

This formation belongs to him and can be refined.

Yun Yifei's spiritual sense and spiritual power surged out to the greatest extent, steadily controlled the defensive shield, raised his hand and stimulated it out several talismans. Several water dragons condensed and roared out. However, the time was not long, and under the burning of the majestic flames, several water dragons collapsed.

"It's not a solution to consume this way," Yun Yifei thought in his heart, as if he wasn't testing the formation, but he really seemed to be trapped in the formation. In fact, as long as he made several magic tricks, he could open a channel in the formation.

"Dragon Shadow Four Stacks"

"Five Dragons Conquering the Sect"

"Dragon energy crosses the river"

Yun Yifei once again used the dragon's body-tempering fist to hit it. When he opened a vague passage in the diffuse flames, he walked the dragon and snake, shot out, and advanced for a while.

"Red plums rush into the courtyard"

"Good rhyme invites the clear moon"

"Autumn chrysanthemums bloom in three paths"

"Wind and thunder are walking under the sword"

...

Yun Yifei's spiritual sense moved slightly, the Dragon Sword roared out, and the Lingxiao Sword Technique was successively used, attacking the flame energy spreading in front of him, which could naturally consume part of the flame energy. As a result, he advanced a distance.

In this way, Yun Yifei used all his methods and consumed some talismans. Finally, he arrived at his destination. He saw a fire tower formed by rich flames in front of him, about a foot high, emitting terrifying energy.

Yun Yifei knew that there were four such fire towers in this formation, which were the "four towers" in the Four Towers Flame Wall Formation.

Seeing this, Yun Yifei inspired a water dragon talisman toward the fire tower, and the fire dragon roared out, but after approaching the fire tower for a certain distance, a more intense flame attacked the fire dragon like a tentacle. In an instant, the condensed flame tentacle wrapped the water dragon firmly. Before the next move, the water dragon collapsed with a "bang" and was wiped out in the flames in an instant.

Not only that, the fire tower released two rich energy in two directions. The fire wall formed by the rich flames on both sides rose up and connected to the formation shield at the top. If it wanted to enter the center of the formation, it would have to destroy the fire wall with brute force.

"The dragon penetrates the clouds"

"The dragon goes out to the sea"

"Dragon Shadow Four Stacks"

...

Yun Yifei waved his arms, and the dragon-tempered fist roared out and attacked towards the fire wall. The dull sound of "bang bang" sounded one after another. Then, dozens of rich flame tentacles extended from the fire wall, attacking the powerful dragon. Time was not long, and the powerful dragon was incompletely attacked by the flame tentacles and collapsed.

"The wind helps the snow dance"

"Three-foot sword wind and cloud"

"Swordmen is strong in the world"

...

The Dragon Sword roared out, and the Lingxiao Sword Technique was used to flow smoothly. With one move, it was a powerful killer move and attacked the fire wall.

“Huhhhh…”

The flame tentacles extended out again on the fire wall, facing the Youlong Sword.

The powerful power of the Dragon Sword faced the flame tentacles. Although the tentacles were cut off from the middle, it also offset the powerful killer moves of the Dragon Sword. Moreover, there were many flame tentacles. Although the Dragon Sword was powerful, it could not handle it and had to avoid it flexibly and retreat while fighting.

Suddenly, after a carelessness, the Youlong Sword was hit by a flame tentacle. Yun Yifei's spiritual sense was not smooth. The Youlong Sword hesitated for a moment and was wrapped around several flame tentacles. The other tentacles also attacked the struggling Youlong Sword.

"Ah", Yun Yifei was shocked, his consciousness

He and the spiritual power surged out wildly, controlling the Dragon Sword, trying to break free from the constraints.

"The rising sun and the clouds are brilliant"

The fluorescent light was flourishing on the Dragon Sword, and the sharp gold aura spread out, fighting against the energy above the flame tentacles.

"Five Dragons Conquering the Sect"

"Flying Dragon in the Sky"

"Raptors look back"

...

The Dragon Body Tempering Fist was continuously shot out, and several powerful dragons roared out, attacking the flame tentacles near the Dragon Sword.

Not only that, Yun Yifei also raised his hand and inspired several talismans.

"Bang bang bang..."

In this way, under the attack of several methods, more than a dozen solid flame tentacles were attacked and collapsed. The Youlong Sword was then called back by Yun Yifei.

Seeing this, Yun Yifei nodded with satisfaction. He was very satisfied with the power of the four towers of the flame wall array. Then, his hands and ten fingers changed rapidly, and magic tricks shot out one after another.

After a moment, this flame world disappeared. It was Yun Yifei who withdrew the Four Towers Flame Wall Formation. He did this just to test the effect of this formation.

If other monks saw Yun Yifei like this, they would definitely scold him for his prodigal son. In order to test the effect of his formation, they actually wasted dozens of primary and high-level talismans, which were a considerable amount of spirit stone.

Yun Yifei did not take it seriously. He carefully checked the Youlong Sword and made it feel unhindered. He then felt relieved and checked the spirit stone at the base of the array.

"Although this formation is powerful, it consumes several times the amount of spirit stones that other formations are. It seems that it is better not to use them easily unless it is absolutely necessary. You need to accumulate spirit stones for the present plan." After Yun Yifei arranged the formation, he placed enough spirit stones at the base of the formation. Although he also guessed that this formation consumed more spirit stones than other formations, he did not expect that it was several times more.

After Yun Yifei put away the formation, he sat cross-legged and recovered from meditation. After all, he consumed a lot of spiritual power and spiritual consciousness in the formation. Fortunately, the time rules in the Ten Thousand Spirit Cauldron are different from those in the outside world, so he has enough time to work on his own affairs.

After several days, Yun Yifei went to the trial ground for other monks to challenge in the afternoon, but few monks came to the stage to challenge. After all, Yun Yifei had demonstrated his methods and spiritual pets, so no monks dared to make trouble for themselves.

Su Moxuan, who was at the late stage of foundation building, was also deserted. However, Yun Yifei also saw his methods. Although few monks came to the stage to compete, it was not without them. When Su Moxuan competed with a Great Perfection monk in the Foundation Building stage, he paid special attention and also saw Su Moxuan's methods.

Su Moxuan's attack methods were also normal. Although there was no particular point, he was also easy to act. Yun Yifei guessed that he must have hidden means. After all, if it was so normal, he would not steadily occupy this position.

Moreover, Su Moxuan also gave Yun Yifei a strange feeling, but it was not specific that there was no place to be the monster.

However, several monks come to the stage to challenge the Black Tower every day, so naturally they all win. Fortunately, the Black Tower is a militant, and they are always busy and warmly welcome the challenges of other monks.

A few days passed in a flash, and the challenge from the monks ended. Yun Huofeng finally decided the three people were Hei Tower, Yun Yifei and Su Moxuan.

During these days, Yun Yifei also refined a large number of elixirs and magic weapons in the space of the Wanling Cauldron. The medicinal materials he purchased were naturally not enough for him. During this period, he also purchased some medicinal materials and weapon refining materials in the Spirit Beast Pavilion. However, in order to avoid attracting the attention of other monks, Yun Yifei handed over to Liu Mang for his time, and naturally marked his contribution points to the token of Liu Mang's identity.
