Hearing that they were going out to fight with the demons, everyone's hearts suddenly shook slightly, they have grown so big, they have never fought with people of other races, today, they are going to see what kind of race the demons are, why do the people in the dark world say that they are so powerful, do they still have three heads and six arms?

Seeing everyone's eagerness to try, a smile appeared on the corner of Chu Chen's mouth, they were looking forward to a battle with the demon clan now, but when they had fought it, it wouldn't be like this.

This time, he went out to fight with the demons, Chu Chen did not let the first step of the people participate, this time, he personally took all the second-step monks here to go, even the clone, Chu Chen did not let him participate, not that the doppelganger cultivation is not good, but Chu Chen does not want to expose his true strength prematurely, if he and the doppelganger become one, his combat power will soar a lot, but now is not the time for him and the doppelganger to become one, only when he goes to the underground demon city, it is the time for him and the doppelganger to become one.

With a thought in his mind, the Xuanyuan Sword came out, was held in Chu Chen's hand, and then walked out of the city wall and went straight to the Demon Array, and the others saw this, and followed behind Chu Chen without hesitation, and hundreds of people instantly passed through the Demon Array.

As soon as he passed through the Demon Array, all of a sudden, the heavens and the earth became dark, and the demonic aura made everyone feel uncomfortable for a while.

"Roar!" As soon as Chu Chen and the others entered the demonic qi, they heard the roar of the demonic beast, and when they looked ahead, they saw a ten-zhang tall, elephant-like demonic beast walking towards Chu Chen. "Kill!" Looking at the countless demon soldiers around the demonic beast, Chu Chen rushed over without hesitation, and with a swing of his sword, a hundred-zhang-sized sword qi tore through the demonic qi, and went straight to the demon soldiers who rushed forward with dazzling light, these demon soldiers looked strange, some looked like people, some looked like beasts, some had human heads and beast bodies, and some had beast heads and human bodies.

Under Chu Chen's sword, where the sword qi passed, hundreds of thousands of demons were killed by the sword qi, these were all demon soldiers, and there was nothing powerful, even if the vitality was strong, it could not block the blow of Chu Chen, a second-step monk.

The others attacked, and the demon soldiers in front of them were not their opponents at all, and they easily killed a large number of them.

"These demons are not powerful, and they can be killed easily. Qian Buregret said, feeling that it was not challenging at all.

"Brother Chu, why don't we kill them directly in the underground demon city?" Luo Chongtian said to Chu Chen, these demon clans are nothing at all, they can't block their way at all, it's better to kill them in one breath now, so as to save a lot of things.

"Okay!" Chu Chen agreed, but he knew that they would not be able to kill the underground demon city directly, and it would not be long before a higher-level demon clan would come over to surround them, and when the time came, they would know how difficult it was for the demon clan to kill.

Everyone followed Chu Chen, all the way into the demon army, along the way, the momentum was like a bamboo, there was no demon clan that could resist their footsteps, in the blink of an eye, they were thousands of miles away from the demon army, they didn't know how many demons they had killed, but this demon army, as if it was inexhaustible, there were endless demons coming towards them every moment.

After killing hundreds of miles, Luo Chongtian said to Chu Chen: "Brother Chu, it's not a way to kill like this, these demons are getting higher and higher, I'm afraid that if we continue to kill like this, not only will we not be able to reach the underground demon city, but we will be killed by the demons because of the exhaustion of mana." "This problem, everyone has already felt it at this time, the mana consumption one by one is extremely serious, and if they continue to kill like this, it is estimated that they can still kill a thousand miles, and after a thousand miles, their mana will be exhausted.

"Now you know that the demons are not so easy to kill, right?" Chu Chen said with a smile, and at the same time, with a swing of the sword, the heads of dozens or hundreds of demons in front of him were slashed off by the sword.

"It seems that we still underestimate the demon clan, what should we do now?" Qian asked Chu Chen without regrets, and everyone else looked at Chu Chen, now that they were surrounded by the demon army, it was very difficult to kill them back.

"Since you don't think you can attack the underground demon city, let's go back. Chu Chen opened his mouth and said, he didn't plan to attack the underground demon city today, just let Qian Buregret them come to realize that it is not an easy thing to defeat the demon clan, let them have a low heart, don't be arrogant, and lead to a defeat in the final battle.

"Brother Chu, how can we go back? Now we are surrounded by many people. Luo Chongtian said with some concern.

"If you can't kill it, then you can only be demonized, and when the time comes, you will all have to fall into the devil's path. Chu Chen said, after speaking, he turned around and went back to kill, and when the others saw this, they had to follow Chu Chen to kill back, although they were surrounded by the demon army, but there were no masters in the demon army here, all of them were demon soldiers, It's just a demon warrior, even the demon generals are difficult to see, this is also one of the reasons why Chu Chen dares to take money and not regret that they have entered the demon army for thousands of miles, and the other reason is that even if the demon commander knows that they have entered the demon army and sends a master to support, they will still be able to rush back at this distance, and they will not be surrounded by demon masters.

Chu Chen led everyone all the way back to kill, along the way, naturally there was no demon to stop, there was no accident, although surrounded by thousands of demon troops, but under Chu Chen's opening the way, everyone still returned to the Demon Array without danger.

When Chu Chen and the others went back, in the underground demon city palace, the masters of the demon realm only learned the news.

"Dare to kill people in our army with only so many people, the courage of the human race is still quite big, go, Ben Shao wants to see who has such courage among the human race!" On the main seat, the young master of the demon clan heard the news, and immediately spoke, and then got up and personally led the demon master to rush away, but, when he just came out of Youming Continent, he heard the news, those human masters have been killed, and none of them have been killed, which makes the young master of the demon clan very disappointed, however, he does not plan to go back, since he has come out, then he plans to take a good look at the human race, this time he came from the demon world, and has not yet fought with the human monks, this time, simply go to see if he can meet the master of the human race。

After Chu Chen and the others returned to the Demon Array, except for Chu Chen, everyone else gasped for breath, and then immediately sat cross-legged on the ground one by one and began to recover their mana, today's battle was too hard, they were all numb to kill, and they didn't know how many demons they had killed, but they felt that the people of this demon clan could not be killed. The people of the demon race are terrible.

Among the people who fought this time, only Chu Chen was the same as a person who was fine, although he also consumed a lot of mana, but it didn't have any impact on him, so when Qian didn't regret that when they recovered, he had already started to discuss other things with others. "There are more demons than I imagined, so if we rely on our own cultivation to deal with it, I'm afraid there is no way to deal with the demons at all. Chu Chen said to Luo Sheng.

"Big brother, the demon clan is too terrifying, in such a stalemate, the entire Youming Realm is afraid that sooner or later it will fall into the hands of the demon clan. Luo Sheng said.

"We need to refine weapons that are specialized in restraining demons. Chu Chen said, when he came out of the demon army, Chu Chen had been thinking about one thing in his mind, that is, a weapon specially used to deal with the demon clan, but for a while, he couldn't think of it, but now after thinking hard, he finally remembered it.

"What weapon can destroy the demons?" For a while, everyone showed curiosity, they can specifically restrain the demons' weapons, this is really good, with this weapon, it will be much easier for them to deal with the demons, perhaps, because of the existence of this weapon, they can turn defeat into victory and drive the demons out of the dark world.

"This one. Chu Chen waved his hand, and in the void, a weapon that looked like a cannon suddenly appeared, this weapon was similar to the appearance of a crystal cannon, but the formation depicted in it was different, and a special material was needed as energy, and the cannonballs emitted by this weapon could blow the demons under the demon lord to pieces, in their previous life, their human army used this weapon to deal with the endless and endless low-level demons.

"Luo Sheng, pass the order, in the entire Dark Realm, collect blue flints, only blue flints can be used as the source of energy for this weapon. Chu Chen said to Luo Sheng, and after Luo Sheng heard it, he immediately went to convey Chu Chen's order.

Although blue flint is rare, it doesn't mean that there is none, Chu Chen knows that there should be this kind of material in the Dark Bright Realm.

After Luo Sheng left, Chu Chen asked Gao Bang to call all the people who knew how to refine weapons, he wanted to concentrate on teaching them to refine this weapon, Gao Bang quickly went to convey Chu Chen's order, and it didn't take long for hundreds of people to come to Chu Chen, these people all have the foundation of refining, although they are not masters of refining, but they still understand general refining.

"Meet the Sect Master!" After everyone saw Chu Chen, they saluted Chu Chen very respectfully.

"Everyone, I summoned everyone here today to let you refine a weapon dedicated to restraining the demons, this weapon has a vital role in our victory over the demons, so next, everyone must listen to me carefully. Chu Chen said.

"Yes!" everyone lifted their spirits and said yes in unison. Then, Chu Chen began to disassemble this weapon, and explained it to everyone one by one, when Chu Chen spoke, many monks of the second step also came to listen, Chu Chen spoke very carefully, try to talk about one step two or three times, so that everyone remembers, especially those formations depicted in the weapon, Chu Chen not only depicted the model in the void, but also taught everyone to draw it several times, this talk, that is, one day and one night, everyone can be regarded as completely understood, however, Chu Chen knows, listens to understand, does not mean that it can be refined, in the process of refining, there will definitely be a lot of unexpected things。

After letting everyone rest for a few hours, Chu Chen began to let everyone refine, he had already ordered someone to prepare the materials, refining at this time, it was really the same as Chu Chen expected, many people did not master the heat at all, the materials were not completely refined, and in the end they could not meet the standard at all, Chu Chen had to let them refine again, refining is a very boring process, and it needs to be careful, sloppy, a little careless, a piece of waste will be refined.

Chu Chen personally instructed them on the side, and after patiently teaching them for two days, finally, the first complete weapon was born, and after that, the others were also very complete, which made Chu Chen feel at ease, this is not a complicated weapon, nor is it a high-level weapon, but it is a little special, but after everyone's efforts, the refining is finally completed.

"Now that you can refine it alone, then you can go to other places and pass on the forging method of this weapon to the refiners in the other military camps. After Chu Chen saw that everyone had refined a good weapon, he asked them to go to the military camps in various places and pass on this refining method to other refiners, so that they could also understand the refining method of this weapon, only by refining this weapon in large quantities, they would attack the demon army in the future, so as not to be exhausted to death by those low-level demons.

With the departure of hundreds of people, it didn't take long for the refiners in the major military camps on the two continents to begin to learn to refine this weapon, and the name of this weapon had a very apt name, called the Demon Exterminator.

Half a month later, Luo Sheng received the news that he had found the Blue Flint Stone, so he immediately came over to tell Chu Chen.

"Big brother, this blue flint is really hard to find, if it weren't for you telling me about the characteristics of the blue flint last time, it is estimated that we still don't know what it is, big brother, just now the news came, they found a vein of blue flint in Hanjiang Continent. Luo Sheng excitedly told Chu Chen the news he had gotten.

"Are you talking about a whole vein of blue flint?" Chu Chen couldn't believe it, after all, as far as he knew, the blue flint was not a whole vein, but an associated thing, some were associated in the spirit stone vein, and some were associated with the veins of iron, gold, silver or other metals, and it was really rare for the blue flint to give birth to a whole vein.

"Looks like God is helping us. Chu Chen smiled, although he also knew that the blue flint was also born with mineral veins, but that was very rare, it was not common at all, today he could find a whole blue flint vein in the Dark Ming Realm, I have to say that it is the will of heaven, for this time to destroy the demon clan, Chu Chen has a little more confidence.

"Pass the order, the blue flint can generally be divided into three grades, let them be divided according to the grade, the bluer the color, the purer the energy in it, and the lighter the blue, the more miscellaneous the energy in it. Chu Chen said to Luo Sheng again.

Luo Sheng left and passed Chu Chen's order out.

"Now, as long as the army of the Twilight Realm arrives and the Demon Slayer Cannon has been refined in sufficient quantities, we can launch an attack on the army of the Demon Realm. The doppelganger spoke.
