Chapter 1831: Burning star fern thorn (1/2)

Ling Qingxue looked at Xia Ruofei with a childlike smile, and couldn't help but smile. She nodded with a smile and said: ”Come on! Burn these bad guys clean!”

Xia Ruofei laughed and began to arrange the formation on the periphery.

After Xia Ruofei's special transformation of this fire attack-based formation, the array materials are basically distributed around the periphery, the largest can be within a radius of about three kilometers, and then concentrated attack inward.

Xia Ruofei chose a distance of more than 20 meters from the star fern thorns and began to arrange the formation. After so many trials, he felt that this distance was relatively safe. It could ensure the maximum effect of the formation without being deployed. In the formation, the star fern thorn attacked.

This formation was basically designed by Xia Ruofei himself, but combined with some of the existing formation principles, the originality is much higher than that of the killer formation, so even though it is the first time he has set up the formation, he still has no Jerky feeling.

Because this formation has been deduced many times in his mind and on paper.

Xia Ruofei placed the array materials one by one around the star fern thorn ring belt, occasionally stopping to check the lower position a little, and then quickly continued to arrange it.

After about twenty minutes, Xia Ruofei placed the last form material in his hand.

He has also circled the entire star fern thorn ring and returned to the position where he had just started.

Xia Ruofei directly took out ten yuan crystals from the Lingtu space.

Then, just outside the formation, placed the ten crystals in a hexagon composed entirely of jade with mysterious formations.

The biggest feature of this formation is that the formation control core, that is, the hexagon where the Yuanjing was placed just now, is outside the formation.

And this formation can use spirit stones, spirit crystals, and element crystals with higher energy levels.

Of course, using different energy sources, the power of the formation is completely different.

In order to make a quick battle, Xia Ruofei directly used the crystals with the highest energy purity, and there were ten crystals in one use, placing the crystals in every position where the energy source was placed.

In this way, basically the maximum power of the formation can be squeezed out.

Of course, the consumption is also obvious.

Xia Ruofei is now in the early stage of the Golden Core, and the technique of ”The Great Dao Jue” is still more energy-intensive. A single crystal can support him in his cultivation for a long time? I used ten of them, which is indeed a big deal.

Xia Ruofei mainly considered that for successfully completing this task? Will he receive a record-breaking reward on the fourth floor of the trial tower? In addition to upgrading the Chu Yuanzhu? There are 1,000 Yuanjing.

In contrast, ten yuan crystals are trivial.

Moreover, Xia Ruofei is not sure now? Is the fire attack effective on this star fern thorn? So he must try it as soon as possible. Once it fails, he can have more time to try other plans.

After Xia Ruofei placed the Yuanjing? Discovered his mental power again? Checked the entire formation? Then he took a deep breath? Pinched a seal and entered the core of the formation.

Ling Qingxue also held his breath? Standing beside Xia Ruofei, looking at the star fern thorn ring ahead.

One second? Two seconds, three seconds...

There was no movement in the formation, Ling Qingxue couldn't help showing a trace of doubt.

But at this moment, at a distance of twenty to thirty meters from the periphery of the Star Fern thorn ring, a ring of flames appeared? A rush of heat swept in? Ling Qingxue subconsciously tightened Xia Ruofei's arm.

Xia Ruofei's expression was very calm? To what extent can the power of this formation reach? He roughly knew it in his heart.

Therefore, Xia Ruofei patted Ling Qingxue's catkins lightly and comforted her a little? As for her gaze, she kept staring at the direction of the formation.

After this ring-shaped flame zone appeared, it immediately began to extend inward. The violent burning of the flame caused a large consumption of nearby air, which accelerated the movement of the airflow. Xia Ruofei and Ling Qingxue both felt that the surrounding wind started to blow.

The so-called fire takes advantage of the wind, not to mention that this is the flame controlled by the formation, naturally, the less and the stronger it is.

The ring of flame quickly penetrated inward, and within a few breaths, it had already entered the attack range of the star fern thorn, and it was less than 20 meters away from the star fern thorn.

In fact, when the formation was activated and the flames appeared, the Star Fern spines had already begun to show restlessness, and those Star Fern spines that looked very similar to camel spines began to sway without wind, and seemed quite disturbed.

The flame of this formation is naturally different from ordinary ordinary flames in the world. In fact, the inspiration comes from the killing formation, the flame formed by the black and sharp glow. The hottest place is almost pure white, and the temperature is high, even the most in the world. The ore that is difficult to melt may not last for too long.

But today, the flames produced by the flame array and the black and scorching flames of the killing array can be said to be of the same origin. The star fern thorns obviously felt the danger, and began to shrink one after another, making preparations for attack.

When Xia Ruofei tried several times, the star fern thorns would attack only at a distance of nearly ten meters, but as soon as the formation flame entered the 20-meter range, the star fern thorns burst out of a large number of thorns. .

The ring-shaped star fern thorn bushes with a radius of one kilometer exploded and shot out a large number of thorns at the same time, like a black shock wave extending from the inside to the outside, the scene was magnificent.

Xia Ruofei and Ling Qingxue were standing at a safe distance, so they remained motionless, standing still watching the big show.

Of course, Xia Ruofei was also constantly pinching out the Yin Jue, carefully controlling the formation, and at the same time paying close attention to the operation of the formation and the energy consumption.

In this situation of squeezing the power of the formation to the extreme, the consumption is quite large. The energy in the ten element crystals is fading rapidly, which is several times faster than the usual consumption of Xia Ruofei during cultivation.

Xia Ruofei did not hesitate to Yuanjing, always maintaining the highest intensity of the formation.

The thorns that burst out are nothing but invisible flames.

Moreover, after the thorns were shot into the ring flame, the star fern thorns immediately took them back, but there were already some thorns that could not be recovered successfully, and it was estimated that they were burned in the ring flame.

Xia Ruofei felt relieved when he saw this scene.

It seems that the choice is right. These star fern thorns still have not got rid of the nature of plants, and flames are obviously their natural enemies.

Xia Ruofei pinched the Yin Jue, and the ring flame further compressed inward.

Star fern thorns burst out frantically, but apart from thorn attacks, they can only dance on the spot, but they cannot form an effective method to deal with flames.

Finally, the ring of flames spread to the outermost periphery of the star fern thorn ring.
