The water snake and fire snake that were blown out of their heads could no longer be used, because before the black water and red flame could be re-controlled, they were chopped up by the gale wind that seemed to be everywhere.

The water snake and fire snake flew out of the ocean and sea of ​​fire where the black water and red flames were located for the third time. However, this time they were particularly huge. Before their tails even broke away from the ocean and sea of ​​fire, their heads reached the door of the Daohuang Palace Palace.

Dong! The fire snake's head lowered its head and rushed forward, and violently hit the palace gate. Although the snake's head did not really hit Meng Xiang due to the invisible barrier, it narrowed the distance between it and the gate to about five feet, which made the eight immortal cultivators who saw this scene obtain a useful information.

The barrier outside the palace gate is soft and stretchy. If the attack strength is large enough, even if it cannot penetrate the barrier, the power can still be applied to the gate. At the same time, without any accident, the snake head was ejected back, like a huge hammer, flying towards Hongyan. He was prepared for it. As soon as the attack began, he moved his position and the snake head was empty.

After seeing this, the eyes of the eight cultivators, including Hongyan, lit up. Although the rebound function of protecting the invisible barrier of the palace gate is very powerful, it can even make the speed of rebound attack exceed the speed of attack, its counterattack direction is fixed. As long as it attacks, it immediately leaves its original position, and no matter how sharp the rebound attack is, it has no use.

This discovery also made the cultivators lose their concerns. If necessary, they can use the most powerful attacks to bombard the palace without worrying about being injured. The so-called happy and sad families, the cultivators were happy, but Meng Xiang frowned. He knew that the shortcomings of the invisible barrier were leaked. It is very likely that they would be attacked by the enemy immediately, which conflicted with him delaying time and striving to refine the sword earlier.

After several more tentative attacks, the eight immortal cultivators led by Hei Shui and Hong Yan were in a mixed mood. They were happy that the shortcomings of the invisible barrier they discovered were really exploitable, while they were worried that the invisible barrier was very tough, and it was difficult for general attacks to pose a threat to it.

Hong Yan looked at the Daohuang Palace and retreated for a while. Then he waved his hand and a red flame flew out of the sea of ​​fire he was in. In a blink of an eye, it reached the top of the Daohuang Palace, and then dispersed silently. It turned into a lot of small sparks. Although many of them were blown away by the strong wind, many of them fell down.

As soon as the sound of the ground, the small sparks suddenly turned into a prairie fire. In the blink of an eye, the entire Knife Palace burned wildly. No, it should be said that the Knife Palace was surrounded by the blazing flames. At this time, the cultivators discovered that it was not just a barrier in front of the Knife Palace, but in fact it had already enveloped the entire Knife Palace.

The barrier is generally in an upside-down bowl shape, completely covering the entire Knife Palace, and as the fire spreads, it shows that there is also a barrier below the palace, forming a sealed whole. No blind spots are left, and there is no loophole at all.

Looking at the Knife Palace wrapped in flames, a hint of joy appeared between the eyebrows of the cultivators, because they found another disadvantage of the invisible barrier. If it is not a direct attack, it will not cause its counterattack. Just like now, this undoubtedly provides them with a good entry point to crack it.

The fire was raging, and even if the strong wind blew, it would not be extinguished. At most, the fire was dimmer and then it would burn again. It would not even directly blow on the invisible barrier, which would make the flames burn even more vigorously. Hong Yan himself and the other seven immortals cultivating eyes were staring at the fire covering the Knife Palace. They were not bored, but wanted to see what would happen if the invisible barrier was scorched by the flames.

Of course, the cultivators all hope in their hearts that the invisible barrier covering the Knife Palace is afraid of fire, and will dissolve under the scorching flames, so that they can face the palace directly. Even if they still cannot enter, it will be better than being out of reach.

The flame burned for a quarter of an hour, and the cultivators wrapped in Hongyan and showed disappointment. They all saw clearly that after so long burning, the invisible shield did not change at all, which was enough to show that the damage to the invisible barrier was really limited.

Although a quarter of an hour doesn't seem very long, it is enough for cultivators to draw some conclusions. If the invisible barrier is afraid of flames, a quarter of an hour is enough to see some clues. Besides, the flame released by the red flame is not an ordinary flame at all. It is not comparable to ordinary flames in terms of temperature or other aspects. Even high-level magic weapons can be easily incinerated.

Hongyan turned his head to Black Water, and the other six immortal cultivators also turned their eyes to him, with a hint of expectation in their eyes, as if they wanted to see what he did. He nodded, raised his hand to the sky, and a blue stream of water flew up from the vast ocean where he was and soon rushed to the top of the Knife Palace.

The moment when Hongyan waved back the flames that burned the invisible barrier, the blue water flow turned into a pouring rain and poured on the barrier, without a trace of heat rising, which disappointed the cultivators. It was obvious that after being burned by the flames emitted by Hongyan for so long, it did not even have any heat.

The cultivators on the scene all knew one phenomenon, that is, something seemed to be not afraid of fire, but if you suddenly pour cold water on it when it was burned to a boil, sometimes it would break suddenly and break into many pieces. As soon as the red flame removed the flame, the black water immediately used water to water the barrier, obviously had this idea, and they did know that many seemingly strong barriers could be cracked in this way, but unfortunately, their hopes were dashed.

The black water was not disappointed, and still allowed the blue water droplets to continue to pour on the invisible barrier. Other cultivators also looked at the blue water curtain that adhered to the shield like glue, and a hint of expectation appeared in their eyes. It seemed that they thought the blue water spilled out of the black water could break the invisible barrier.

The expectations of the cultivators are not without basis. Through the previous tentative attacks, they found that the invisible barrier covering the Knife Palace was soft. Their shape was a bit like jelly. According to their experience, barriers of this nature were often afraid of the cold. If they were stimulated by excessive coldness, they would be frozen directly or become very crisp and hard, and would fall apart when attacked.

When the blue water curtain completely covered the invisible barrier, Hei Shui's expression became serious. He raised his hands, his palm facing the barrier, and then a strange wave burst out from his palm. The next moment, covering the invisible barrier, the blue water curtain formed ice, forming an ice shell, and pressed on it, as if putting on a piece of clothing. It was crystal clear and bright, with blue light flashing, and it looked very beautiful.

However, the cultivators had no time to care about whether it was beautiful or not. They all widened their eyes and watched the changes of the invisible barrier, and Meng Xiang was also a little nervous. Although his experience was not as rich as the eight cultivators outside, he knew nothing less than them at all, and he was still very clear about some means of cracking the barrier.

After a moment, Meng Xiang's heart finally let go. Because with his eyes, he did not notice any changes in the invisible barrier after being frozen. It was obvious that it was not afraid of freezing at all, but he immediately laughed. The Knife Palace was refined by Ximen Jue. As a dignified sword emperor, the barrier created by the entire spiritual world could not be so useless.

The cultivators were outside the Knife Palace. Although their vision could not be compared with Meng Xiang, it did not mean that they could not see the invisible barrier clearly. Soon they all found that the cold was ineffective against it. However, Hei Shui obviously had no intention of giving up, and still pushed a stream of strange cold air out of his palm and placed it on the barrier. It was obviously preparing to try whether the shield could be frozen and hard.

As time went by, a strong cold air spread from the blue ice layer above the shield, freezing the air wherever it passed, forming an increasingly larger iceberg with the invisible barrier covering the Knife Palace. It was not until the size of the iceberg reached twice the size of the invisible shield that the black water stopped the delivery of cold air.

Looking at the solid ice covering the invisible barrier, Hei Shui suddenly turned his head to Red Flame, and a strange light shone in his eyes. He nodded to him, then reached out and grabbed it. The entire huge ice shell broke off from the invisible barrier and was raised high.

Almost at the same time, a huge pillar of fire flew out from the sea of ​​fire where the red flame was, condensed into a mountain-sized flame hammer in the air, rushed out suddenly, and blasted over to the invisible barrier covering the Knife Palace. During the flight of the invisible barrier, a stream of force from heaven and earth blessed the hammer head, making it stronger and stronger and stronger. Later, it could even shatter the terrifying sharp blade of wind with the surging dark force.

The giant flame hammer rushed up high, and it stopped thousands of feet away from the invisible barrier. Then he turned around and blew down fiercely, like a meteor falling from the sky, dragging its long tail and smashing it down. The cultivators, including Hong Yan, all looked expectant, while Meng Xiang was a little nervous. Although he was inside the Knife Palace and did not have to face the giant flame hammer directly, he still felt the powerful destructive power it had.

The giant flame hammer fell very fast, and it hit the invisible barrier in an instant. The barrier immediately sunk inward. The pit almost wrapped around half of the hammer head. Then the barrier immediately returned to deformation. The powerful rebound force generated suddenly bounced the huge giant flame hammer away, returned the same way, and was sent to the deeper part of the gale layer at a speed almost twice as fast as when it fell.

Meng Xiang felt a slight vibration and immediately calmed down again. This made him smile. The magic weapon refined by the Sword Emperor was indeed unusual. On the contrary, Hong Yan and other immortal cultivators all showed disappointment. In addition to testing the invisible barrier, they also let them know that the intensity of the barrier is extremely high. With a huge flame hammer just now, Hong Yan did not use all his strength, but at least six or seven points of strength. Such a strong force still cannot shake the barrier. It is probably very difficult to break it.

After the continuous failure of cracking the invisible barrier, Hei Shui and Hong Yan chose to stop and gathered together to discuss. After about a stick of incense, Hei Shui took action again, released a stream of water from the ocean where he was, flew to the Dao Palace, and turned into heavy rain. Then, cold air came out of the palm of his palm, frozen the water on the invisible barrier that enveloped the Dao Palace, forming a large blue ice shell.

What is he going to do? Seeing Heishui repeating his actions not long ago, Meng Xiang was confused, but soon a flash of inspiration flashed in his mind. Could it be that he was thinking... his face suddenly looked ugly, and it seemed that what Heishui was going to do next would be very serious.
