Yan Xing looked at the spirit boat that could change the size freely under Xu Lingfeng's feet and was amazed, this was the first time he had seen such a magic weapon, although when he first entered the Hidden Scripture Pavilion, the spirit also issued himself twelve spirit swords with black weapons, but in terms of tallness, it was far worse than this small boat.

Yan Xing patted his head and secretly scolded why he forgot the twelve swords, and then his mind moved, and the star stone was included in the storage dragon scales, and instead appeared on his claws were two spirit swords, one blue and one red.

"It's been so long, if I hadn't just remembered it, I would have almost forgotten it. Yan Xing looked at the dim luster spirit sword, and suddenly an interesting idea came to mind, and he turned his head to Xu Lingfeng with a cruel smile.

Xu Lingfeng snorted coldly, and chased after Yan Xing in the spirit boat, he raised the staff in his hand high, his slightly narrowed eyes flashed with a terrifying light, and obscure spells kept popping out of his mouth, the staff was like a torch, and the spar at the top lit up with green brilliance.

Yan Xing watched Xu Lingfeng cast the spell curiously, but he didn't expect that this human being was actually a magician, their cultivation system and fighting methods were completely different from those of his own dragons growing in the east, even in the Dragon Gorge, the competition with other young dragons was mostly based on hand-to-hand combat.

In the cultivation system of the East, spells are a very general range, which includes both spells that rely on the support of the true qi in the body, as well as various fighting skills that amplify themselves or rely on melee combat, and for example, the cloud puff body method practiced by Yan Xing is also a kind of spell, but because of age and cultivation, the young dragons basically only know the spells of fighting skills.

The cultivation system of the West is different, they are mainly magicians, and their spells also refer to 'magic', magic is generally a spell that releases fireballs, and what flows in the body of a magician is not true qi but magic power, magic and true qi are essentially different but have many similarities, and no one can explain why so far.

The biggest commonality between the two systems is in the division of realms, the East and the West are basically similar, even if those mages have magic power in their bodies, they will also condense the Yuan Infant in the Yuan Infant Period.

Therefore, this was the first time Yan Xing had seen spells other than fighting skills, so he naturally would not interfere with Xu Lingfeng's spellcasting.

"Wind crack!" As Xu Lingfeng's spell fell, the surrounding environment changed dramatically, and a wind knife nearly five meters wide appeared out of thin air, its speed was extremely fast, and the air made an overwhelming tearing sound, this wind knife was enough to cut through a steel plate one or two meters thick.

"Wind Knife?" Yan Xing almost laughed, after staying in the Wind Thunder Valley for so long, to say that the most familiar one is thunder and lightning, and the other is the wind knife, although the strong wind in the Wind Thunder Valley is not so powerful, but the density is far from being comparable to a wind knife.

Seeing the wind knife coming in front of him, Yan Xing flapped his wings unhurriedly, and made a clever sideways turn in the air, easily avoiding it.

"Let's use all the spells one by one, or you won't have a chance later. Seeing that the spirit boat was chasing after him, he stepped back a little, and then mocked Xu Lingfeng mercilessly, Yan Xing suddenly felt that he had a little bit of an evil dragon.

Hearing his arrogant words, Xu Ling's face was flushed with anger, and he couldn't wait to rush up and break off his dragon horns, no matter how he said that he was also a young man, he reached the genius of the Triple Heaven of Cutting Veins at a young age, although it was not particularly amazing among human beings, but it was a huge shame to be repeatedly played by a young dragon who had cultivated to the Sixth Heaven of Gathering Souls.

Xu Lingfeng took out a glass bottle from the ring, opened the cork and poured the liquid inside into his mouth, and after a while, Xu Lingfeng's face appeared abnormally ruddy, he quickly began to cast spells, this time the spell chanted was even more subtle, the spar at the top of the staff was like a small green sun, releasing a dazzling light, as his voice became more and more high-pitched, the wind around him seemed to respond to his call, and they all wanted to converge in his direction.

His gorgeous aristocratic clothes moved with the wind, even the golden curly hair fluttered messily under the strong wind, his face was unprecedentedly solemn, countless air currents formed a huge cyclone around him, and the terrifying air flow made Yan Xing have to be serious, his eyes were firmly fixed on Xu Lingfeng in the center of the cyclone.

Such a crazy air flow is very unfavorable to Yun Fei's body method, but it can also test how far he has cultivated this body method in the past five years.

Xu Lingfeng had already completed the spell, and he laughed and said, "Hahaha! Young Dragon, now I will give you a chance to sign a contract with me, otherwise you will only die under this storm!" The cyclone seemed to have formed a huge tornado at this time, and many trees on the ground were involved in it, and they were instantly cut into powder by the fierce wind in it, and they were sprinkled one after another after blowing to a height of 100 meters.

The trees in the Dragon Domain are harder than ordinary steel, which is enough to show that the power of this spell is extraordinary.

At this time, Yan Xing found that he was actually locked by a strong suction, and he was constantly being pulled towards the huge tornado, in a hurry, he used the cloud puff body technique to dodge a few flying wind knives, but found that it was difficult to get rid of it again.

"Given you a chance, you really dare to be scared. Yan Xing snorted coldly, but instead of retreating, he flew towards the tornado.

Outside of the tornado, there were dozens of invisible wind knives, and when Yan Xing couldn't cope with it, he would raise the spirit sword in his claws and split the wind path with all his might, but despite this, his body was still colored.

"Hahaha, stupid young dragon, you are only a soul gathering six heavens, how can you be better than me, who has cultivated several times higher than you, you can sign a contract with me with peace of mind!" Xu Lingfeng couldn't stop laughing, the wind was still blowing, and the dragon scales on Yan Xing's body were more and more damaged.

"I think you humans not only have a disease in the head, but also need a cure for the mouth. He sneered, the chill in his eyes intensified, and his golden eyes became brighter and brighter.

"Drink!" Yan Xing split a nearby wind channel, and then his figure became blurred, as if turning into a hazy cloud and mist, and the wind channel cut was constantly stirred, and in just a few breaths, he broke through the six or seven wind knives that blocked him, and came to the vicinity of the tornado.

What a strange posture! The dragons watching the play below all let out such an exclamation, and even Jin Xuanzhuo, who was about to stop the dragon and one person in the distance, was taken aback.

This kind of body does not seek speed, only weird and changeable, can advance or retreat, and cannot be prevented, which is really terrifying!

"You ......" Xu Lingfeng in the center of the storm didn't expect Yan Xing to break through the outer wind knife so quickly and come inside.

"Even if you get here, you can't break through my magic at all, and you will only have a dead end if you consume it!" Xu Lingfeng was full of confidence, he increased his strength again, and the suction of the tornado was even greater.

Yan Xing looked at Xu Lingfeng, who was surrounded by a violent wind, and he did have some difficulties in his heart, although the cloud body method was strange and changeable, it was only a body method, although he could make his body shape change quickly when he cast it to reach a state where he could not be attacked like a cloud mist, but he was helpless when the attack was too intensive.

But......

Yan Xing looked at Xu Lingfeng, who was holding a staff in the center of the tornado but couldn't move, and then observed the direction and law of the wind......

Obviously, the air rotates rapidly around the central axis of the tornado, that is, the position of Xu Lingfeng, and is attracted by the extremely reduced pressure in the center of the tornado, and the air flow is sucked into the bottom of the vortex from all directions, and then becomes a vortex rotating upward at high speed around the axis, and this wind is cyclonic......

Although I don't know what the unit of my own power is now converted into Newton, I can get the ratio of my strength to the gravity of the tree being blown away through ordinary experience, and then divide the upward acceleration equal to the upward component of the wind minus the gravity of the tree and divide it by the mass of the tree to get the ratio of the upward component of the wind to your own strength......

In a short period of time, Yan Xing combined the three disciplines of physics, mathematics and geography to analyze this storm more thoroughly, which is obviously the horror of Xueba!

He showed a hearty smile to Xu Lingfeng in the storm: "Who told you that I want to go in?

"Huh?" Xu Lingfeng was stunned, he didn't understand what Yan Xing meant, but looking at that smile, he vaguely felt that something bad was going to happen.

"Hey, hey. Yan Xing let out an evil laugh and threw the flying sword in his claws to the side of the storm with just the right amount of force, and did not fly directly towards Xu Lingfeng.

All the dragons present thought that Yan Xing had thrown it in the wrong direction, but then he took out eleven spirit swords, all of which were thrown at different positions of the storm in the same way, and none of them were aimed at Xu Lingfeng.

"Teacher, what is Yan Xing doing?" Xiao Ke'er asked puzzled.

Jin Xuanzhu stared at those flying swords for a long time, and suddenly he seemed to understand something, and a shocked look appeared on his face, as if he couldn't believe the scene in front of him.

"It won't be ......"

The next scene made all the dragons who were watching, including Xu Lingfeng, fall into a deep shock!

He ...... He's a monster!" I don't know who exclaimed.

I saw that the twelve spirit swords changed direction under the action of the storm, and at the same time gained a huge speed, and actually stabbed at Xu Lingfeng from the storm, and the angles of several swords were even more tricky, almost surrounding him to death, and there was no way to escape!

"How is it possible?!" Xu Lingfeng exclaimed, his face turned pale all of a sudden, he was already powerless to defend himself, and if he was stabbed by these swords, there was only one way to die!

Yan Xing showed a smile, the white dragon teeth made him look a little terrifying.
