"Boom!" With a loud explosion, the thunder cannon barrel with some special material suddenly burst in the flames, forming a fire ball more than two meters high, and at the same time shooting a bright red cannonball. The fiery red cannonballs soared into the air at the darkest hour before dawn, and the roar that came out of it would attract many demonic patrols roaming around.

The demon patrols entrenched near Su Wan and the others naturally saw a red light rising into the air, and at the same time, their keen ears also heard the roar coming from the air, so the demon who had been standing still instantly rushed up and galloped at high speed in the direction of the sound.

After the demon disappeared far away, Su Wan, who had been staying on the ground and not moving, immediately crawled out of the hidden corner, and without slapping the soil on his body, he rushed towards the location of the rock camp unusually. They all knew that time was of the essence, because the red light would attract not only the demons but also the demons elsewhere. Therefore, they must leave the hiding place as much as possible, rush into the camp under the rocks, and if the demon finds out that it is just a decoy, he will definitely fold back and search for it.

Although even high-level intelligent demons may not have a high level of intelligence, when they find out that they have been deceived by the bait, they will definitely search around and even think of the reason for the bait. Although demons may not be able to detect human traces, it is absolutely inevitable to raise their vigilance in a short period of time. This is not good news for Chen Kai and them, once the demon's vigilance is raised, then this vigilance will always be maintained.

For demons, they are very obedient to the upper and lower classes, and those ordinary demons who only have combat intelligence are more accustomed to obedience than demons with higher intelligence. As long as the demon leadership stipulates that they must patrol ten times, they will definitely not patrol nine times, and of course they will not patrol eleventh times. At the same time, once the demon high-level increased their vigilance against Chen Kai's infiltration, then the intensity of the patrol would definitely increase, and the chance of encountering the demon patrol on the road behind would become even greater.

"Xiao Kai? What do you say we should do now? After settling the tired Su Wan and them, Su Xinghe crawled out of the hole and asked Chen Kai on the side, at this moment Chen Kai was holding an eagle eye telescope to check the situation in this wilderness with the help of a glimmer of light in the sky.

"What else can I do? Let's take one step at a time! Chen Kai sighed, looking through the binoculars, he could clearly see that the area in the sky in the distance where Su Wan and the others had stayed had been completely surrounded by the little demons flying in the sky. Hundreds of little demons were constantly hovering in the sky, and even from time to time they released a fireball to light up the sky and shoot downward, and a roar came when the fireball landed.

"Is that kid Lu Xiaofeng back?" Chen Kai put down the telescope in his hand and turned his head to ask Su Xinghe, this thief who was responsible for luring the demon should be back soon in Chen Kai's estimation, but there didn't seem to be an image of him entering the cave in Chen Kai's image.

"Eh, don't you say that kid really doesn't seem to have come back?" Su Xinghe patted his head and found that it seemed that Lu Xiaofeng really didn't come back, he couldn't be sure, he hurriedly crawled back to the underground space to check the number of people, and found that the other party did not come back.

"Hey! Four-eyebrow one, where did you go? Chen Kai heard Su Xinghe's words and had to immediately call Lu Xiaofeng with a communicator, Chen Kai, who had read martial arts novels, did not call the other party by name, but directly called the other party with the nickname in the novel.

"Brother Kai! I'm outside, no, I'm in a hole I dug myself, and now I can't get past me when I see a team of demons coming towards you, be careful! Lu Xiaofeng's voice was unusually nervous, in fact, he originally wanted to rush to the rock camp as much as possible, but he ran into several groups of demon patrols on the way, including two demon mages with magic staffs. At the moment when he saw the two mages, Lu Xiaofeng subconsciously activated the thief skill and hid in the shadows, but when he flashed into the shadows, a trace of strange fluctuations swept over him and almost swept him out of the shadows.

If it weren't for Lu Xiaofeng's ability to control his strength and breath at the moment he was swept by the fluctuation, it is estimated that he would have instantly escaped from the shadow state and then be discovered by the demon mage, so he would never dare to go forward after the two mages left with the team. Directly turned around and found a place to hide, dug a cave and hid, if it wasn't for Chen Kai's call, Lu Xiaofeng might not have remembered where the demons were heading for a while, but after hearing Chen Kai's call, he immediately patted his head and thought of the direction in which the demons were heading. While searching around, they walked almost straight towards the rock camp where Chen Kai was, thinking of the terrifying probing spells of those demon mages, Lu Xiaofeng could hardly control and wanted to call out.

"Quick! Fast! Block the entrance, hurry up and everyone hide in the newly dug lower cavern at once, and bury this place with dirt! Chen Kai was almost speechless in shock when he heard Lu Xiaofeng's words, thinking of the terrifying ability of the mage's exploration technique, he felt that the cave under this rock was not very safe, and immediately began to direct people to move deeper underground.

A large amount of dirt is dumped out of the player's backpack and piled directly into the space originally used to support the tent, while those without dirt hurriedly move towards the underground space and try to dig new layers there. Because no one knew whether the demon mage's detection ability would pass through the ground and reach the underground space a few meters below, once Chen Kai was discovered, it would be impossible for them to even escape.

However, some players felt that since it was not safe to hide underneath, why not just escape, but soon they found out that this idea was even more silly, it was indeed unsafe to hide underneath, but it was relative. After all, the depth of the mage's exploration technique is limited, although Chen Kai and the others don't know how many meters the demon's exploration technique can reach, but it is unlikely that they can penetrate three or four meters deep strata, so Chen Kai will let them move down and fill the upper space with soil. When Chen Kai and the others continued to stuff the soil into the upper layer, they also continued to expand the depth of the underground space, and dozens of players with big shoulders and round waists worked hard to dig the soil to dig the hole deeper.

“***！ What are you still digging, hurry up and let Lao Tzu enter the tent and go offline! Chen Kai looked at his hot companion and felt that the green tendons on his head were constantly jumping, everyone knew that now the source of oxygen in the underground space was cut off, so tireless digging would consume more oxygen, and when the time came, they would either be killed by the demon or suffocated directly due to lack of oxygen. Although Fei Yun and the others took into account the lack of oxygen in the underground space when they built it, they used the reeds in the swamp to control the ventilation pipes in advance, but these pipes were too thin, and at the same time, in order to ensure that the smell of people inside was not smelled by the demons, they had to use various methods to filter the air, and as a result, the air provided by a reed pipe became very small. If it weren't for the fact that Fei Yun had buried enough reed pipes, it is estimated that the underground space would have been short of oxygen for a long time.

But after all, the reed pipe is too thin, and once the oxygen consumed by the player is too intense, it is estimated that there will be a lack of oxygen immediately, so Chen Kai directly drove most of the people off the line, leaving a few people to stay in the underground space to accompany Fan Clery and them.

"It's coming!" When the last player to go offline disappeared from the game in the white light, Fan Kerry, who was sitting on the ground, suddenly said something, and then Chen Kai was stunned for a moment. At this time, Chen Kai suddenly discovered that he didn't know when Fan Keri's level had actually increased, and the original level of 79 had become level 80. Don't look at it, this is only such a small level, but it is a big gap. Level 79 can be called a pseudo-eighth-order, but the pseudo is the pseudo, and it is not a star and a half worse than the real eighth-order warriors. While Savaskilo and the others had not yet reacted to the demons outside, Van Krry had already felt the energy fluctuations of the demonic mages above.

Hearing Fan Clery's words, everyone immediately stopped the movements in their hands, controlled the rhythm of breathing, did not speak, and waited quietly, as time passed minute by minute, there was a trace of cold sweat on everyone's foreheads, slowly oozing out there. At this moment, everyone felt that time passed so slowly, and every second seemed to be as long as a year. It wasn't until Fan Cree quietly breathed a sigh of relief, and then after saying a word, Chen Kai slowly patted his chest and relaxed.

"That's it! Those demons are gone! When Fan Clery said this, his heart was also relieved, although the eighth-order powerhouse could use his power to sense the situation in the outside world, it was very vague and dangerous. If it weren't for the low level of the demon mage who came, it was estimated that Fan Kerry would have been discovered the moment he probed the other party, so his luck as a new eighth-order great swordsman was really good.

"Looks like we're going to have to huddle underground for a while, and if we get out now, we're going to hit the devil's gun!" Chen Kai sighed and said, although he knew that there was not much time limit for this thief's trial mission, and at the same time, he also knew that in fact, after discovering the Demon Gate, the thieves had already completed the task and could go back. But for the sake of the greater good, or for the sake of a higher system reward, Fei Yun wants to go deep into the hinterland of the Demon Gate, which is related to the completion of their trial task and the size of the reward after completion. In fact, if it weren't for Chen Kai's promotion, he would have gone crazy with Fei Yun and them, in fact, he had already mixed with them, it was just another task. Chen Kai looked at Fan Clery and they glanced at them and then sat down slowly, when he accepted Fan Clery's task, he knew that this was a big trouble, especially as the task progressed, the level of the task gradually became higher, and now it has become a B-level mission.

"Stay up for now! Old Blood informed the Dark Dagger and the Fourth that they should be careful of the Demon Mage, and then temporarily stop the action and hide for a few days! Hey, what kind of broken task is this, which not only delays leveling but also tortures people! Su Xinghe patted the soil around him depressedly to vent the depression in his heart, after all, now the player's level has increased rapidly, and many players have completed the promotion trial. At the same time, the rank ranking they occupied by Su Xinghe had been surpassed by others, so the amount of experience they gained was too small. The amount of experience gained decreases, and the rate of experience accumulation is much slower than that of players elsewhere, so among players who have reached level 50, players on the battlefield have the slowest experience accumulation.

"That's it! Don't lose your temper, if you feel like you have nothing to do, practice vindictiveness! Chen Kai sighed and said, and then sat down by himself, at this time, the most efficient way to save air and body is to sit down and practice fighting qi.

"Hey!!" Everyone sighed, and then slowly fell silent, and the dim underground space slowly fell silent, except for the breathing of a few people moving through the space. When Chen Kai was woken up by a roar, he found that nearly five hours had passed unconsciously. His Dou Qi value has increased by nearly fifteen points in five hours, of course, this value is really not high, but it is already quite good. At least it was the first time that Chen Kai had gained an average of three points of Douqi in an hour, and it was also the first time he had reduced his holdings for so long.

"! What the hell are these demons messing with!" Chen Kai was a little depressed listening to the terrifying voice above the soil layer, if it weren't for that voice, it was estimated that he was still silent in the environment where the fighting qi was running, and it was not good that he could continue to gain some fighting energy. Of course, in fact, Chen Kai also knew that it was unlikely, after all, the long-term operation of the fighting spirit made his body drop sharply, and a feeling of hunger came from his body.

"I guess I'm testing the underground environment, trying to blow us up with a spell!" Su Xinghe shook his sore shoulders and said, in fact, he woke up two hours ago and prepared some food for Van Clery and them, and of course, the most important thing was to try to dig up the dirt and dig out a new space. The size of the underground space restricts the amount of air inside, and only when the space becomes larger, the more air Chen Kai and his family can breathe. It's just that there is not much oxygen supplemented by relying on a few thin reed pipes, so after digging a few more times, Su Xinghe will feel shortness of breath, which makes him very uncomfortable.

"These damn minks really don't stop at all!" Chen Kai also felt a little depressed when he heard Su Xinghe's words, but he also had no choice but to pray that their spells were not powerful enough, and at the same time, he also prayed that those reed pipes would not be destroyed by the impact of the explosion.

When Chen Kai angrily waved the mining pickaxe and kept digging the dirt on the ground, they also made a loud roar in their northern Fei Yun. The roar terrified the thieves on the banks of the river, for it was too loud and seemed too close, and the huge tremors made the earth above the underground layer loosen, and the planks and the wood against them creaked continuously.

Fei Yun was woken up in his sleep by the sound of wood, but this feeling of being woken up was not good, especially in the face of constant roaring noises. When they heard the roar outside, several thieves instinctively wanted to climb out to check the situation, but they were stopped by the alert Kashgar. In his opinion, going out now is simply looking for death, even if they start the shadow step in time, but where to hide in the sun.

"Dig it! Dig hard, only by digging down can we have a way to live, otherwise the soil layer above will collapse and we will be buried alive! The dark dagger sighed and said, as the trembling sound became more and more intense, the entire underground space seemed to be shaking, and after seeing this situation, everyone struggled to dig the soil below, constantly deepening the depth of the underground space. In less than five minutes, a new hole was dug up to a meter deep, while others on top piled up the earth to form a layer of soil that was supported on both sides of the space to make the entire hiding place as stable as possible. Everyone is digging like a tireless mole, just to be able to live longer.

The huge roar lasted all day, and during this time, both Chen Kai and Fei Yun were all suffering, and the worst thing was Lu Xiaofeng, who was hiding outside alone, and he almost curled up in the ground like a mouse, hiding to survive this painful time. His ears were trembling from the roar, and his mouth was waving as he spoke on the team's channel. However, although the mouth is not good for talking, but they finally survived, in fact, Chen Kai who was hiding underground and they all survived, and those demons also stopped after a whole day, and it is estimated that no one can survive under the ground that was bombed like a crater.

As for what the outside environment had become, Chen Kai only found out after three days had passed, during which a group of sub-players relied on mine pickaxes to dig a 100-meter-long passage in the underground space. If it weren't for the lack of oxygen in the tunnels, they would never have dug up to get out of the safety of the underground.

"These demons are terrifying!" When Chen Kai saw the terrifying ground environment outside through the night, he couldn't help but take a breath of cold air, because in his field of vision, the originally flat ground now became like the surface of the moon where he lived when he was a child. It's just that compared to the surface of the moon, the range of the numerous round craters is not particularly vast, only one or two meters larger than ten centimeters deep. But the sight of hundreds of round pits covering the wilderness still made Chen Kai and them stunned, and when Chen Kai was looking at the ground outside in a daze, Lu Xiaofeng, who risked the danger to come out, discovered Chen Kai's location, and then rushed over desperately. He spent the past three days almost in fear, because there was no tent, so he did not dare to go offline, so he could only hide in the hole and sleep, until he was sure that there were no demonic footsteps outside, and then crawled out in the night.

"555 has finally found an organization, *** do you have anything to eat, I'm dying of hunger!" Lu Xiaofeng grabbed Chen Kai's arm with a face full of fear and said, although he carried a lot of food in his backpack, the amount was not very much, especially in that environment, except for eating, running fighting qi and digging holes, he couldn't think of any way to relieve his fear, and the consumption caused by a large amount of exercise was also terrifying. Originally, Lu Xiaofeng didn't bring much food, but he ate the last piece of bread during the day, if he didn't find Chen Kai and them, it is estimated that he would be hungry and then face the end of exhaustion and exhaustion.

"Damn! How did you end up like an African refugee? Chen Kai looked at Lu Xiaofeng, who was squatting on the ground and desperately nibbling on barbecue and bread, with his black mud disguise to be a famine African refugee.

"You tried to be hungry all day and see!" Lu Xiaofeng is large and consumes a lot of food, and he has never tasted hunger since he entered the game, because he always has some food stuffed in his backpack. However, stuffing food does not mean that there will be more stuffing, many players have the habit of stuffing food, but the amount of food will never exceed three days, because their travel time is only three days at most, unless they are exploring a large ruin, then they will carry more food.

"That's it! When we're full, let's hurry away! Taking advantage of the fact that there are no demons around, let's rush to the fourth and them! Chen Kai patted Lu Xiaofeng's shoulder, and then gestured to Su Xinghe, who waved his arm directly downward, and then one by one the players quickly crawled out of the ground and rushed towards the place where Fei Yun and them were.
