Ling Lan's dragon head shook: "I sensed that the Hidden Demon was still hiding in this cave, but I couldn't find the exact location. She paused: "Bai Xiaofei, I have shielded this cave with my mental energy, and the hidden demon can't ask for help from the old ghost Xu Fu, but the time I shield it is only 15 minutes, and after 15 minutes, we can't find the hidden demon and have to retreat." ”

Bai Xiaofei's face was gloomy, he knew that if he couldn't find the hidden demon and killed him within 15 minutes, he would never find such a good opportunity in the future, and the hidden demon would definitely chase and kill his party who left the Japanese slaves, and his group would be able to escape, but ordinary girls like Asakanan and Minako would be in danger.

Ahhh

Bai Xiaofei sighed lightly, endured the pain in the broken leg, and limped forward and pressed Sun Xiaohou's shoulder: "Little monkey, the master knows that you want to avenge your father, but you can't use brute force like this." The more anxious you are, the more likely the hidden demon is to sneak attack. ”

Sun Xiaohou squeaked the long stick of the wire worm in his hand, his eyes were red, and he was panting heavily, he originally wanted to break free of Bai Xiaofei's hand, but Bai Xiaofei's fingers just clasped several meridians on Sun Xiaohou's shoulder, he struggled and finally calmed down.

Sun Xiaohou slammed the long stick in his hand to the ground: "Master, I'm just unwilling!" ”

Bai Xiaofei patted him on the shoulder: "Don't worry, we still have more than ten minutes now, as long as we crack the stealth technique of the hidden demon in these ten minutes, killing him is just a matter of effort." ”

Sun Xiaohou's eyes lit up, that's right, he still has a chance, he said loudly: "Master! Kill the Hidden Demon, you must let me do it! ”

Bai Xiaofei nodded heavily: "Of course, the revenge of killing his father, of course, should be avenged by his son!" ”

The hidden demon was beside him, sneering in his heart, this Bai Xiaofei had such a big breath, and he wanted to break his stealth technique in more than ten minutes? Just now, he fought with himself alone, and was beaten half to death by himself, and he didn't come up with a way to crack the stealth technique, and now he couldn't think of it in a hurry.

However, it's better to be careful, after all, now in the cave of the mother tree, his corpse brother has almost been killed, the enemy is strong and I am weak, so I should find a better hiding place, and the hidden demon's eyes turned, and he thought of a good place to hide-

Bai Xiaofei looked at the underground cave, and pointed to the mother tree that was still insisting on cultivating the corpse brother: "Destroy it." ”

Yu Xiaojia, Xiaopang, Chen Hao, appetizer, Chen Xinyi, etc. responded in unison, and cut and smashed around the mother tree, and the mother tree more than ten stories high was dug up by them, and fell down with a bang, and countless half-developed Japanese corpse brothers rolled out of the broken tentacles, rolling on the ground.

Chubby laughed and stepped on the trunk of the mother tree: "I worked hard to go to the slaves to kill the mother tree, which is the most painful today, I am really not used to secretly laying viruses on the mother tree, I always feel sneaky." ”

Yu Xiaojia said with a smile: "It turns out that you like to be a lumberjack, that's good, when we retire and have nothing to do, you can go up the mountain to cut wood every day." ”

Xiaopang looked at Yu Xiaojia affectionately: "As long as I am by your side, even the boring work of chopping wood and knocking stones is the most interesting thing for me." ”

Yu Xiaojia didn't expect Xiaopang to say such sensual love words at such a time, although the two were engaged, Yu Xiaojia was still a little unaccustomed to Chubby's cheekiness, and quietly stretched out her finger and pinched Chubby's waist: "I'm going to die, what crazy words do you say when you have this kind of life." At such times - inappropriate. ”

Xiaopang grabbed Yu Xiaojia's hand with a cheeky face: "It's okay, how to kill the hidden demon is naturally up to a smart person like Bai Xiaofei to worry about, as long as he finds out the location of the hidden demon, I will immediately help Sun Xiaohou kill the guy who hides his head and tail." As for me and Xiaojia, no matter when it is suitable or not, I only know that now with Xiaojia and you, I am very happy. ”

Yu Xiaojia was moved and funny, "You give me a little quiet, let Bai Xiaofei think about it, how to find the hidden demon." ”

Bai Xiaofei was on the side, hearing the whispers of Yu Xiaojia and Xiaopang clearly, looking around, Xiaohui, Xiaowei, Qiao Feng and others also looked at him with expectant eyes, he smiled bitterly in his heart, how could everyone think that they could find a way to recognize the hidden demon stealth technique? I really have this ability, and I won't be injured by the hidden demon again and again just now, but I won't be able to fight back.

Bai Xiaofei glanced at the underground cave again, the mother tree was completely destroyed, even the thick root system covering an area of dozens of acres was dug out, the trunk was smashed into several pieces, and a handful of fires were burned into charcoal, countless Japanese slave corpses were on the spot, the statue of Maitreya Buddha had turned into a piece of powder, and the combined cow corpse brother was sucked dry of vitality because of continuous rebirth, and became a dried corpse.

But where is the Hidden Demon? The underground cavern is so big, he really wants to find a place to hide, even if everyone uses a carpet search, they can't find it.

Think about it, think about it, what is the weakness of stealth?

Bai Xiaofei carefully recalled the several attacks he had received from the Hidden Demon - he couldn't detect the location of the Hidden Demon, and the speed of the Hidden Demon was also extremely fast, so he couldn't allow himself to fight back at all. Yes, the key points of stealth are to shield various perceptual abilities, such as sight, hearing, smell and psychic energy, and second, to be fast, only extremely fast speed can make the enemy unable to track and counterattack.

What if you could reduce the speed of the Hidden Demon?

Bai Xiaofei thought hard, using a net and a rope to interfere with the hidden demon? No, it's too pediatric.

If Lulu's mother were here, she might be able to fill the cave with cobwebs and entangle the hidden demon - but time does not allow, and even if Lulu's mother spits out the spider silk, it will not be able to fill the cavern.

Yu Xiaojia looked at Bai Xiaofei and thought hard, and carefully looked at the time - there were only five minutes left.

At this time, Xiaopang leaned over and asked in a low voice, "Xiaojia, are you bored?" ”

Yu Xiaojia was stunned: "What did you say?" ”

Xiaopang pointed to the remnants of the mother tree that was still burning: "The only entrance and exit of this underground cave was blocked by Ling Lan, and the mother tree kept burning, don't you think it's stuffy and hot here?" Give and wipe the sweat. As he spoke, he handed Yu Xiaojia a crumpled handkerchief.

Yu Xiaojia was moved and amused again, knowing that Xiaopang was using such a messy method to show her concern for herself, she took the handkerchief and was about to wipe her sweat, when Bai Xiaofei, who had been stunned next to her, suddenly snorted: "I found a way!" I've found a way! ”

Everyone gathered around at once: "What? Found a way to discover the hidden demon? ”

Bai Xiaofei said in a loud voice: "Yu Xiaojia, can you increase the pressure of the air?" ”

Yu Xiaojia said: "But you can, but the scope can't be too big." ”

Bai Xiaofei nodded, and said to Ling again: "Ling Lan, I heard that after you turned into a dragon, you have already mastered the power of water and fire, right?" ”

Ling said, "That's right, what do you want me to do?" ”

Bai Xiaofei said loudly: "Yu Xiaojia, Ling Lan, I want one of you to increase the pressure of the air in the cave, and the other to heat the water with fire to produce a large amount of steam. ”

Everyone was stunned, and Xiaopang muttered, "Bai Xiaofei, what are you doing here?" How I feel like you're going to turn this cave into a king-sized pressure cooker - high pressure and hot steam. ”

Bai Xiaofei laughed and said, "That's right! I'm just going to turn this cave into a pressure cooker! This method is still what you said just now, Chubby, the stuffy and hot inside the cave made me think of it. I'm going to turn this closed cavern into a high-temperature, high-pressure area, so as to slow down the Hidden Demon's movements and force him to reveal himself! ”

Yu Xiaojia and Ling Lan immediately understood Bai Xiaofei's intentions, adjusting the atmospheric pressure was easy for Yu Xiaojia, while Ling Lan spewed out a pillar of fire and a column of water from his mouth at the same time, and the water and fire blended, and immediately turned into a large cloud of steam, enveloping the entire cave.

Pressure cooker, this underground cave has really become a veritable pressure cooker, Qiao Feng felt the sudden increase in pressure on his body, and said with a smile: "It's fun, it's fun, I seem to have returned to my hometown." "In the other world, the pressure is constantly fluctuating, and Qiao Feng doesn't pay attention to this pressure change at all.

But the others were a little uncomfortable, Chen Hao gasped: "Good guy, this is going to burn me as ribs." ”

Nanako's strength was too weak, and she couldn't hold her butt and sat on the ground for a long time, Xiao Hui hurriedly went over, opened the hatch cover of the Iron Tree Mecha, and let Nanako and herself squeeze in the cabin - the cabin of this Iron Tree Mecha is constant temperature and pressure, and there is air conditioning, and Xiao Hui is not affected by the outside world at all.

The pressure and temperature in the cave continued to rise, and everyone's movements slowed down, but Sun Xiaohou stiffened up, vigilantly sweeping around, trying to find the traces of the hidden demon. He knew that Master Bai Xiaofei tossed such a big move in order to avenge himself, and he definitely couldn't waste this opportunity!

The Hidden Demon finally panicked.

His stealth technique is unique in the world, it is taught by Xu Fu Ancestor himself, and it is not an ordinary old routine that affects people's senses to become invisible, but to break through a small void and let himself enter a different time and space, so that naturally any known detection ability cannot sense himself.

However, there is a flaw in this method, that is, the requirements for mana are very high, and if you want to continue to break through the void, the mana required is massive, and this kind of mana can only be done by top masters like Xu Fu and Long He, the hidden demon was originally just a ninja, and after being mutated into a corpse brother by Xu Fu, although there is a great breakthrough in skill, it is not enough to maintain the breaking void indefinitely.

Therefore, the hidden demon is actually constantly shuttling back and forth between the void and the current time and space, just like opening a space-time door, going in and out, constantly reincarnating, so as to save the mana consumed by himself.
