At this time, Ge Tongshan's whole body was emitting a dazzling white light, and the light was so bright that he couldn't look at it directly. Starting from the position due north, one after another façade Dan formations began to appear. Each of these Dan Arrays was a person's height, in a perfect circle, and in a matter of seconds, they filled every inch of space on the outer edge of the formation, and then these Dan Arrays began to develop upward, constantly replicating, and soon gathered together, forming a huge semi-circular sphere, and the sphere was covered with the entrance Dan Array.

"I can hold out for about half an hour!" Ge Tongshan's voice came from the center of the array, "It only takes a short time to gather all the butterflies, and how much I consume next depends on how fast you can do it!"

"Stand back, it's time to start!" Zhang Zhongjian said in a deep voice, taking the lead in retreating. The others followed him backwards and stood together. Almost at the same time, all the entrance Dan arrays shone together, and several meters of electric light poked out from each Dan array, flickering continuously, like a hedgehog made entirely of thunder and lightning, and the piercing sound sounded intensively, stabbing people's ears painfully.

At this time, in the city, people's curiosity about butterflies has passed. As night fell, the sporadic lights began to flicker. In the dimly lit night, the butterflies began to show a faint blue fluorescence, and countless fluorescent lights gathered together, so that people who had lost interest gradually began to appreciate it again. Some people were on the balcony, some on the side of the road, pointing and admiring, and many took out their mobile phones to take pictures. Suddenly, a piercing sound sounded in the city, and in the corners that people had never noticed, hundreds of blue-white Dan arrays lit up at the same time, and at the same time emitted electric light scattered like thorns, which had no effect on the city, but had a huge suction force on the butterflies in the air. The butterfly gate seems to be dragged by hundreds of invisible tornadoes, and they all gather together to gather in all corners of the city, and there seem to be hundreds of hundreds of inverted spiral giant landscape lights tens of meters high in the city, flashing with fluorescent blue light, and the whole city seems to have become a dream world that flashes this blue light. This vision lasted less than half a minute, and after half a minute, all the fluorescent light disappeared. The butterfly disappeared completely from the city, leaving no trace. The night finally completely obscured the city, countless lights came on, and the city returned to its usual quietness.

Outside the venue of the gymnasium, on the periphery of the Luo Tian Shenyin Great Array, about half a foot opposite the Dan Array at all entrances, an identical Dan Array appeared. Countless flocks of butterflies gathered together, with every two opposing Dan arrays as a channel, swarming in, as if it was not a flock of butterflies gathering, but countless black and blue pillars inserted from the array. After just a dozen seconds, all the butterflies were submerged in the formation, the newly generated Dan Array all disappeared, and the original entrance Dan Array also quickly dimmed, and then disappeared. Only one remained, still shimmering with a faint white light.

"It's time to go in, pack up the guys and keep up!" Zhang Zhongjian patted Ye Fei on the shoulder, picked up two big bags in his hand, and dodged into the formation, before him, Yun Huan and Xinlan had already entered first. Ye Fei agreed, and Lin Yufei took the rest of the big bag, and then entered.

"Oh!"

As soon as they entered, both Ye Fei and Lin Yufei were shocked by the scene in front of them. The interior of the formation space is not small, it is a standard cylindrical space, the diameter is enough to be thousands of meters, which is larger than the entire field outside the formation, and the height is also about 30 meters, the four walls and the top and bottom are dark wood yellow, and the wood grain is the pattern of ash willow, as if it is an antique study, but it is extremely huge. At this moment, above this "study", all the dream butterflies are gathered together, as if they have not realized that they have changed the environment, and slowly wave their wings in the air. Because of the sheer number, it looks like a huge blue, black, and brown cloud that is constantly changing colors to form abstract paintings in different poses.

"Don't be in a daze, junior brother, it's your turn next," Zhang Zhongjian patted Ye Fei who was in a daze, "Do you need our help?"

"Oh!" Ye Fei reacted, "Next, we have to spread these thermite agents in every space here, which requires the help of the second senior brother's wind technique, and then ignite my own Thor crossbow." And then we need to get out of here as soon as we ignite. ”

"Is it so powerful? We can't prevent it?" Zhang Zhongjian asked.

"It's not that I can't prevent it, I'm not that conceited. Ye Fei scratched his head and smiled, "But I don't know if the air in this space is connected to the outside, if not, the violent burning will completely deplete the oxygen in this place later, and we will not be able to breathe." ”

"Then let's go out first, you two have to move quickly. Yun also snorted and left from the exit first, followed by Xinlan, Zhang Zhongjian smiled and patted Ye Fei, and also left.

"It's our turn. Ye Fei clapped his hands, stepped forward and poured all the thermite on the ground, there were several cubic piles, piled up in the center of the space. "It's up to you, senior brother, I can't do it yet, I have to try to ...... these powders with them," he pointed to the butterflies above, "...... Mixed together, and then we're going to leave through the exit. ”

"Got it. Lin Yufei agreed, and with a wave of his hand, a huge but not very strong tornado appeared, instantly blowing away the thermite on the ground, and in the blink of an eye, there was reddish-brown smoke and dust everywhere. "By the way, the density of such a thing scattered in such a large space is too small, right?

"Don't worry. Ye Fei looked confident, "I have a large amount of nanocatalyst doped in it, which is specially made by me, and this density is enough, I'm a little worried about whether Mr. Ge can hold it." ”

"Mr. Ge wouldn't like to hear you say that. Lin Yufei muttered and withdrew his wind technique, "Almost, this distribution density can be maintained for one or twenty seconds, we should go out." ”

"Roger. Ye Fei snapped his fingers, pulled Lin Yufei to the exit, and made a backward posture. Then he stretched out his right hand, flashed the Thor crossbow he had already put on, fired three in a row towards the center of the field, and then shouted "Go!" and jumped backwards out of the exit.

Lin Yufei's reaction was a little slower, but his speed was already much faster than Ye Fei, and it was only a few tenths of a second after Ye Fei left, and he had already retreated. Even so, he saw the horror of this new thermite. In the moment before he left, the high heat brought by an electromagnetic bomb with more than ten times the speed of sound instantly ignited the thermite in the air, and in an instant, it seemed that the whole world had turned into a dazzling bright white, like an incandescent wall that was pushing towards him. The entrance to the formation was closed the moment he left, but he still felt the terrible temperature, and his face was still burning a few seconds after leaving the entrance.

At this time, all the entrances of the Luo Tianshen Yin Great Array had been closed, and only the flat formation map was left in the venue, and the original few steel ingots in the formation had disappeared, and only Ge Tongshan was still sitting in the center like an old monk. Lin Yufei, who finally retreated, had just stood still, and the figure of Ge Tongshan, who was sitting upright, suddenly trembled violently, and at the same time, the formation on the ground emitted a strong white light. The white light flickered for only two seconds, and with a "boom" it turned into a bright yellow wall of fire more than two meters high, as if there were countless oversized acetylene welding guns on the ground spraying at the same time. After a second, all the light flames disappeared, and the array on the ground was completely invisible, leaving only a large area of charred black color, the same as the place where Ge Tongshan was sitting before.

"Mr. Ge!"

"Ge boy!"

Zhang Zhongjian and Ye Fei shouted at the same time.

"Don't worry, it's okay. Lin Yufei's voice came from behind them. The two turned around at the same time, just in time to see Lin Yufei gasping violently a few times, and was helping Ge Tongshan to stand upright. Ge Tongshan looked a little embarrassed, his head was covered in sweat, his clothes were scorched in a few places, and there was a trace of blood on the corner of his mouth, but it didn't look serious.

Ye Fei and Zhang Zhongjian breathed a sigh of relief at the same time, and even Yun Huan's face on the side relaxed a little. Ye Fei hurriedly went up to support Ge Tongshan, and at the same time used his growth ability slightly: "It's okay, it's scared to death!"

"Stinky boy, do you want to kill me!" Ge Tongshan finally reacted, pushed Ye Fei away, and scolded, "Can't you control the weight a little!"

"Uh...... Accidents. Ye Fei scratched his head, and said with a somewhat embarrassed smile: "Isn't it that the second senior brother helped you out, at least the result is good." I'm really sorry, Mr. Ge, it's the first time I've used this thing on a large scale, and I haven't mastered the dosage. ”

"Stinky boy!" Ge Tongshan scolded again, and he was helpless. Ge's family is also a master of Danshu, and he often encounters similar situations, he is not particularly disgusted by Ye Fei's statement, but he is mainly frightened by what happened just now. At that time, he was still controlling the formation with all his might, and he had no time to escape, if Lin Yufei hadn't seen the opportunity quickly, he would have been trained into slag by the high temperature of more than three thousand degrees. "But what are you...... What kind of hot agent thing, it's really terrible, it's just artificially created samadhi real fire. ”

"Eh, hey, Mr. Ge, you don't blame me. Ye Fei finally put his mind at ease, "But is there really such a thing as Samadhi True Fire?"

"It's a fire at the conceptual level. Ge Tongshan replied casually, "Your senior sister's fire skills are very close. ”

"It's not enough, the fire just now is closer, but it's not there yet. Xin Lan said suddenly, and Ge Tongshan and Ye Fei both jumped. Turning her head to look, Xinlan had closed her mouth and stopped talking.

"Ge boy, have they all been wiped out?" Yun also asked, "You didn't use a container, is it okay?"

"Don't worry, it's clean, even my Dan Array has been burned clean. Ge Tongshan responded, "You old guy, your luck is really not ordinary." ”

Lin Yufei and Ye Fei glanced at each other, revealing a puzzled look. Xinlan was still expressionless, only Zhang Zhongjian showed a knowing smile. Yun also straightened up, snorted, and showed a hint of smugness in his expression: "That's something you can't envy!" and said to the disciples: "This time it's handled well, let's rest, if there is anything to talk about tomorrow!"
