For the other six intermediate martial artists, the oscillation frequency of the Yuan Force is between 7,200 and 8,100 times, and the Yuan Force capacity is between 4,000 and 7,000 wisps.

At this moment, Qian Kun and the other seven people formed a Seven Heroes Killing Array, surrounding Yitian's body, rotating at an extremely fast speed, forming a whirlpool, separating Yitian from the outside world.

In the sky, the seven-headed beast spun with it, and the entire sky was blood-red and shrouded in flames.

The eye waves moved slightly, a strange smile appeared at the corner of Yitian's mouth, the light world outside his body oscillated slightly, the brilliant light flowed on the surface, and all kinds of flame patterns emerged in an endless stream, transforming into everything in the world, including grass, trees, mountains and stones, birds and beasts, which looked very beautiful.

At this moment, in the face of the seven people joining forces, Yitian chose not to move, revealing arrogance and conceit, which made the onlookers feel angry.

Xu Ruohua and Lan Xin stood on the periphery, watching from a distance, their expressions were different, and they were silent with each other.

Xu Ruohua looked worried and looked at the field motionlessly.

Lan Xin was relatively calm, paying attention to the actions of several martial emperors in the audience from time to time.

At this moment, Qian Kun and the others had completely activated the formation, and the seven people were in their respective positions, and the oscillation frequency of the Yuan Force on each of them was different, but it was consistent with the formation.

"Suffer death, Nangong Feiyu!"

The heaven-shattering roar came out of Qian Kun's mouth, and with the rolling rage, one giant beast after another rushed out of the fire cloud, turning into pillars of light, and rushing towards Yitian in the whirlpool.

At that time, the seven great martial venerables in the formation each had a shining light on their bodies, and their qi veins were completely connected to the seven giant beasts in the fire clouds, controlling the overwhelming flames and launching a fierce attack on Yitian.

Because of the formation, the space around Yitian was restricted, and a space-time barrier appeared, which was seriously distorted and deformed, making it impossible for people to perform the technique of spatial transfer.

Yitian was unmoved, he had no intention of avoiding it at all, and there was a look in his eyes that outsiders could not understand.

The highly oscillating flame expands, shrinks, stretches, and changes thousands of times in an instant, beyond the reach of the naked eye.

This change seemed cumbersome, but it was actually to break through the defensive light realm outside Yitian's body and directly attack his physical body, thus destroying it in one fell swoop.

It's just that Qian Kun and the others underestimated Yitian, and they didn't really understand Yitian's strength.

In an instant, the endless flames converged into pillars of light, changing at a frequency of nine thousand six hundred times in an instant, constantly changing, acting on the light realm outside the Yitian body, trying to shatter the light realm, or break through the defense, but the result was unsuccessful.

There are more than 20,000 layers of light outside Yitian's body, and the frequency of each layer is different, and they are staggered and fused with each other, forming a relatively closed barrier, which can filter all attacks and make it impossible for external forces to penetrate.

"The clown who jumped over the beam also wanted to kill me, it was just a dream. ”

Disdainful eyes and contemptuous smiles appeared on Yitian's face, which made the attacking seven angry noses crooked.

However, the seven of them joined forces to set up a formation and cast a killer blow, which was enough to destroy people whose strength was ten times greater than their own, but they could not cause the slightest damage to Yitian, which made Qian Kun and the others shocked.

At this moment, outside Yitian's body, the Light Realm couldn't help but tremble, which was the result of the collision between the power of the attack and the defensive Light Realm.

This tremor is actually a high-speed vibration, caused by the collision of forces against each other.

Although Qian Kun and the others' attacks could not penetrate the Yitian Light Realm due to the frequency, the continuous attacks had been washing through the Light Realm, and the vibration was inevitable.

In this process, Yitian has been transforming the frequency of the Light Realm, allowing those pure Flame Yuan Forces to gradually infiltrate the outer defenses, enter the inner space, and then refine them one by one, and finally devour them.

This method is peculiar because most people use defense to bounce the force of the invasion as much as possible to avoid being harmed.

The way of guiding, differentiating, and devouring like Yitian is theoretically feasible, but there are few people who can really do it.

The reason for this is that this method is very dangerous and requires excellent control ability, and a bad one is equivalent to ignition.

Second, this requires extremely strong strength and proficiency in the art of devouring alchemy, otherwise they will also be supported to death.

Yitian's physique belongs to the Godhead, with infinite plasticity, can accommodate all things in heaven and earth, and has infinite power.

Previously, when Yitian killed Niu Tielong and Zhang Hong, he used a similar technique to directly devour and refine the lifelong yuan power of the two, thus greatly increasing his strength.

Niu Tielong's Yuan Force was as many as 8,500 wisps, while Zhang Hong's Yuan Force was around 6,500 wisps.

These two people were cultivating Xuan-level upper-level techniques, and Yitian devoured the lifelong cultivation of the two of them, and the capacity of the Yuan Force in their bodies increased by 15,000 wisps in one fell swoop, from the previous 180,000 wisps to 195,000 wisps.

Yitian can devour the power of all kinds of castes in the world, because he has mastered the mystery of the origin of heaven and earth, and can communicate with all things in heaven and earth, including the Yuan power of various castes.

Once, when Yitian fought with Nangong Zhenghao, he could directly seize the fire yuan power that belonged to Nangong Zhenghao's hard cultivation.

The reason for this is that Yitian is able to communicate with the Agni Yuan Force, and second, Yitian has a special physique.

At the beginning, the Earth Spirit Grass was actively stored in the Yitian body because of the special constitution of the Yitian.

And Yitian's special physique comes from two aspects, one is that the Netherworld Island has experienced the Eight Extremes of Divine Power and the Qi of the Nine Suns, and the other is the Thousand Moon Soul Refining Technique in the Thousand Moon Cave Heaven.

For today's war, Yitian has actually considered it for a long time.

Although he is now a high-level martial artist, if he wants to be promoted to martial emperor, he must not practice the Fire Dragon Technique.

And the Fire Dragon Technique is an earth-level upper-level magic technique, which is thousands of times stronger than the Agni Technique, and if you want to directly cross from the Xuan-level Upper Rank to the Earth-level Upper Level, it is equivalent to jumping three levels in a row, which is impossible to achieve in the cultivation realm.

Normally, in the process of cultivating the truth, in the process of ascending to the realm, the choice of the method is to ascend layer by layer, and will not skip the level directly.

That is to say, in the current situation of Yitian, it no longer makes sense for him to cultivate the Xuan-level upper-level method, so he should cultivate the ground-level lower-level method, and after cultivating to improve, he will continue to cultivate the ground-level middle-level method, and then cultivate the ground-level upper-level method.

But now, Yitian is jumping three times in a row, from the Agni Jue to the Fire Dragon Jue, although he can overcome the difficulties in the middle, but the process will be extremely difficult.

Because of the sudden and steep increase in the compression ratio of the Yuan Force, the average person's body simply cannot bear it, and the transformation of the Yuan Force will be many times more difficult.

Just like last night, Yitian cultivated the Fire Dragon Technique, and spent a night consuming 20,000 wisps of Fire Yuan Power, only to get 20 wisps of Fire Dragon Yuan Power.

This thousand-fold compression ratio, if you change to other martial artists, even if your body can withstand it, this transformation process will take several days, or even dozens of days.
