Hearing Chu Chen's order, everyone immediately divided the labor, Xu Chang, Guang Changyang, Zhu Jian and other ten people went to repair the formation, and the others followed Chu Chen into the demon army, hundreds of second steps of power to shoot together, suddenly, the demon army was instantly forced out of the gap, those soldiers guarding the gap, seeing Chu Chen and their arrival, immediately breathed a sigh of relief, if there were no more reinforcements, they were afraid that they would not be able to hold out for long.

"You go and rest for a while, we'll leave it to you. Chu Chen said to the tens of thousands of soldiers who had been sticking here and sworn not to retreat, now that they are here, they can let these soldiers have a good rest.

"Thank you Sect Master, we are not tired, we can still persevere!" Guarding here were the disciples that Chu Chen had brought down from the Twilight Realm.

"Go and rest, hurry up and recover!" Chu Chen's face sank and he ordered, at this time, even if they can still hold on, but after a while, they can't hold on, they can't hold on, who will guard this place?

Seeing that Chu Chen's face became dark, suddenly, the surrounding disciples immediately obediently went to find a place to rest, Chu Chen didn't bother to care about them, a sword swinged, the sword qi flew out, and killed hundreds of demons in an instant, and the others also followed, in a blink of an eye, the demons who attacked the gap were all killed by them, but these demons were not afraid of death, and they were not frightened to retreat because the same clan in the gap died, but instead attacked more and more frantically, not caring about life and death at all, it's just that hundreds of second-step powers came here, these low-priced demons are cannon fodder at all, there is no one who can resist at all, as many as they come, Chu Chen They will kill as many as they want！

It didn't take long for Xuchang and them to finish repairing the formation, Chu Chen raised his hand, twisted a seal, and entered the repaired formation, and suddenly, where the gap was, suddenly, a light rose, and the gap was completely repaired.

"Withdraw!" Chu Chen saw this, a sword slashed out, and suddenly, a sword of hundreds of zhang size fell from the sky, and fell into the demon clan that was not afraid of death, tens of thousands of demon clans, under Chu Chen's sword, all died, a sword mark of hundreds of zhang size on the ground was particularly eye-catching, a sword cut down, Chu Chen did not see the result, turned around and left with everyone, and went to the second gap.

The second gap is only two hundred miles away from them, and now, on top of these tens of thousands of miles of Hengduan Mountain Range, the integer number of the gap is still increasing, and almost a stick of incense will be torn open by the demon clan, but Chu Chen's repair speed is not slow, and it can repair a gap in almost half a stick of incense.

Under the leadership of Chu Chen, hundreds of second-step powers were able to quickly repair the gaps, but when Chu Chen and them repaired to a hundred gaps, Luo Chongtian's mana was also extremely amazing, and after repairing a hundred, they had already consumed almost fifty percent of their mana, and the gaps in the formation were still increasing, and it was not a way to go on like this, but for a while, Chu Chen couldn't think of any other way, so he could only just mend it like this, and now, he could only take one step at a time, hoping that after the demons heard that the entrance to the demon world of the underground demon city was sealed, the Seven Nights Demon Lord could rush back, so that they would have enough time to repair it。

It's just that to Chu Chen's disappointment, the Seven Nights Demon Lord did not send people back, but had the appearance of wanting to break through the Hengduan Mountain Range, and frantically ordered the demon soldiers to charge, without caring about their lives.

"It seems that the demon clan is determined to break the formation of the Hengduan Mountain Range, and we can only be prepared for a long battle. Chu Chen observed the Seven Nights Demon Lord's side for a while, only to see that the Seven Nights Demon Monarch did not appear to lead the army to retreat at all, Chu Chen knew that this time, they could only grit their teeth and persevere, and they could not give up, otherwise the formation of the entire Hengduan Mountain Range would be destroyed by the Demon Clan.

"The strength of this demon clan is even stronger than we guessed, and it seems that we can only hold on. "Luo Chongtian Dao.

"Brother Chu, don't worry, we will definitely persevere to the end. Ye Linquan also said to Chu Chen.

Seeing everyone's determination, Chu Chen's heart felt a little more at ease, but he also knew that this was not a question of persistence or not, but the reason for excessive mana consumption, even if they had a tough heart, without the support of mana, it would be in vain.

Chu Chen continued to lead everyone to repair the magic circle, and in one breath, Chu Chen led everyone to repair almost two hundred gaps, at this time, everyone was already tired, and Chu Chen had to let everyone rest and meditate on the spot to recover their mana.

Everyone also knew that even if they gritted their teeth and insisted, without the support of mana, they were afraid that they would all die in the hands of the demons, and they would even be manipulated by the demons and become puppets of the demons, so when Chu Chen ordered them to recover their mana, they did not hesitate to meditate on the spot to recover their mana, Chu Chen was also seriously consumed, so naturally he had to sit down and recover his mana, but when he had just breathed for almost an hour, the demon array in the place where his grandfather and they were guarding was finally torn open by the demons, and Chu Chen had always left a trace of divine consciousness there, and naturally he was the first to react。

"You continue to meditate here to recover your mana, and I'll go over there and have a look. Chu Chen explained to everyone, and then went straight to his grandfather's side, this is all his family, there must be no matter!

Chu Chen got up, and a big void shift appeared beside his grandfather, at this time, the formation was just torn open, and the surging demons rushed in from the mouth, and the soldiers guarding here did not react immediately, and were killed by the demons several, if it wasn't for Chu Chen's appearance, a sword slashed towards the mouth, and killed the demons who rushed in, I am afraid that there will be more soldiers to be killed by the demons. "Be careful, don't be careless!" Chu Chen slashed out with a sword, and at the same time shouted loudly, reminding the surrounding soldiers, which made the surrounding soldiers react, and hurriedly attacked the demon clan who rushed in again.

"Chen'er!" Seeing Chu Chen, Chu Bufan relieved himself, just now he also wanted to attack the demons, but it was still a little slower, if it wasn't for Chu Chen's timely move, I was afraid that the demons would really rush in.

"Grandpa, be careful, these demons are not afraid of death, don't show mercy!" Chu Chen nodded to his grandfather, and then his heart moved, Haotian Tower flew out of Chu Bufan's body, and instantly flew above Chu Chen's head, a light curtain hung down, enveloping Chu Chen, Chu Chen stepped out in one step, came to the gap, held the sword in his right hand, took out the formation base with his left hand, and began to repair the formation, Chu Bufan saw this, and also followed a step to the gap, helping Chu Chen resist the crazy attack of the demons, after that, Chu Xiong also rushed out, and shot together beside Chu Bufan, attacking the demons, Chu Chen saw this, his heart moved, and the light curtain of Haotian Tower instantly shrouded the two of them, after a cup of tea, Chu Chen finished repairing the formation, and the three of them returned to the formation together。

"It was so dangerous just now!" Chu Bufan wiped the sweat on his forehead and said to Chu Chen: "Fortunately, Chen'er appeared in time, otherwise at least hundreds of people here would have been killed by the demons." "Hundreds of people died, it was only Chu Bufan's most conservative estimate, but Chu Chen didn't say much, now that the formation is repaired, it should be able to hold on for a while.

"Brother Chu Chen, you have to be careful. Qin Yanran and the others walked over and said to Chu Chen.

"Don't worry, you have to take care of yourselves. Chu Chen nodded, and then gave the Haotian Tower to his grandfather, after finishing speaking, a void shift, disappeared, now, the attack of the demon clan has not weakened in the slightest, but is becoming more and more crazy, those gaps that have not been repaired, are torn apart by the demons more and more, if you don't repair these gaps, I am afraid that it will not last long, and the demons will rush into the Hengduan Mountain Range.

"How's your recovery?" Chu Chen asked them when he returned to Luo Chongtian's side.

"Some have been restored, and a few places should be repaired. Luo Chongtian opened his eyes and said to Chu Chen, and the others also opened their eyes and said to Chu Chen, they have all recovered some mana and can continue to repair.

"Let's go, then. Chu Chen said, and then, everyone got up, through the nearest teleportation array, to the place with the largest gap, this place, now the gap has been torn to ten zhang, countless demons crazy impact, even if the demon exterminator keeps attacking, can not block all the demons, the tens of thousands of soldiers guarding here have suffered heavy casualties, and now it is another group of soldiers who come here to resist, and it seems that they can't hold on for long, undoubtedly, Chu Chen's arrival has greatly boosted the morale of the soldiers here, and hundreds of second steps can rush out together, instantly blocking the offensive of the demons, Xuchang They quickly repaired the formation, and half a stick of incense took more time, They repaired the formation, and Chu Chen and the others quickly returned to the formation.

"Alright, go to the next one!" Chu Chen took a deep breath, looked at the operation of the formation, and after making sure that there was no problem, he said to Luo Chongtian and them, everyone followed Chu Chen, through the teleportation array, and came to another place with a gap of almost ten zhang, which is the second largest gap area in the formation today, the demon clan who is not afraid of death is frantically attacking here, the casualties of the Terran soldiers guarding here are almost more than half, and the reinforcements are still on the way, if there is no reinforcement within the time of a stick of incense, I am afraid that it will not be able to hold it, the situation is extremely critical, fortunately, Chu Chen and they arrived in time, and it took almost a stick of incense to repair the formation here, just, Just when they just repaired the formation, in a place hundreds of miles away, there was a gap, at the beginning it was only one zhang, but in a blink of an eye, it was reopened by a demonic beast, and this demon clan was invulnerable, ordinary magic weapons and spells could not hurt it at all, for a while, this demonic beast actually rushed into the Hengduan Mountain Range, wreaked havoc there, and trampled a human monk into a meatloaf with one kick, and the strength was extremely terrifying!

"Not good!" Chu Chen's divine sense saw this scene, and he knew that the demon clan was going all out to attack that place. "Four hundred miles to the east, you guys hurry up!" After speaking, Chu Chen came to this place with a big void move, the place where he appeared was the sky above the demonic beast, and he slashed it without hesitation, this is not an ordinary sword, but a god destroying power that has just been cultivated quite a little, this sword went down, and instantly drained Chu Chen's mana, although the consumption was terrifying, but the power was also extremely good, a sword went down, the demonic beast was killed on the spot, and the flesh and the original god were all killed.

Seeing that this terrifying demonic beast was finally dead, everyone finally breathed a sigh of relief in their hearts, and then saluted Chu Chen one after another.

"Bring the wounded down to heal, reinforcements will soon arrive. Chu Chen asked everyone to be exempt, and then ordered.

Luo Chongtian and they dared to come over, kill the demons who rushed in, and block the gap, but at this time, if they want to repair the gap here, it is no longer possible, because, many masters of the demon clan suddenly appeared here, forming a confrontation with them, as long as they repair the formation, these demon masters will definitely attack.

"Brother Chu, it seems that they already know that the entrance to the Demon Realm has been blocked. Qian said to Chu Chen without regrets. "They don't go back to the Underground Demon City, I'm afraid they want to destroy us in one fell swoop, otherwise they won't attack so wildly. ”

"What Qian Lao said is not wrong, but I am afraid that this time, they are determined to break our big array. Chu Chen nodded.

"Obviously, with the strength of our several realms, I am afraid that we will not be able to resist it. "Luo Chongtiandao, Hengduan Mountain Range, the defense line stretches for hundreds of thousands of miles, although all the gaps are added together, they are only a few tens of miles in size, but, there are so many gaps, the ghost knows which gap the demons will quietly put the main force in, and now this is obviously the focus of other demons, they will stay here, and they won't be able to hold on for long, and the mana they consume now is too serious, and they will only hold on for two hours at most.

"Brother Chu, it seems that we have to plan how to do a good job of retreating. "Ye Lin Quandao, outside the formation, there is still a monstrous demonic energy, and there are many demon shadows, they have killed a lot of demons, but there are still many, many demons, they have the defense of the formation, the support of the demon slaying cannon, and they have not been able to completely resist the attack of the demons, and if it goes on like this, the consequences can be imagined.

"Listen to the people of the human race, it is impossible for you to resist my demon army, and those who know each other should surrender quickly, otherwise their lives will be killed in an instant!" A demon general shouted at Chu Chen, at this time, Chu Chen's demons on their side did not attack, but formed a confrontation with them, behind these demons, there were demon masters who kept gathering, and the demon attacks at other gaps did not seem to be as crazy as just now.

"Qiye, are you hiding behind and seeing no one?" Chu Chen glanced at the demon general, then looked at the back of these people, and said lightly.

"It's really curious, in this world of the human race, someone will know Ben Shao, did you come down from there?" A lazy and self-satisfied voice came from the demonic energy, and then, a demonic beast like a phoenix flew over, stopped in front of the formation, above this black phoenix-like demonic beast, stood a beautiful young man, this is the royal family of the demon clan, only the royal family of the demon clan can be so handsome.

This dark phoenix-like demonic beast, named Black Sparrow, is very powerful, and it is quite at the peak of the Terran Sky Realm.
