In the face of the invitations of the heads of the five major sects, Dong Chen was not a little excited in his heart, he had come to the door by himself before, and wanted to let the mainland of Zhongzhou know about the Heavenly Demon.

Now these people already know about the Heavenly Demons, but if they want to truly integrate them, in Dongchen's opinion, the time is not ripe enough.

Even if these people have some losses now, only Kunlai Lake has been destroyed by the mountain gate, but the other sects have not suffered much losses, and they still have a big way out, so Dongchen doesn't think that if he makes a move now, they will really unite as one......

In Dongchen's estimation, the interior of Zhongzhou was completely wiped out, including the destruction of other mountain gates, and they would know what the Heavenly Demon was to them......

Dongchen did not plan to set up the second line of defense in the interior of Zhongzhou, but in the north......

Dongchen wants to take advantage of this time to build an army on the side of the camp, and at the same time lay out one after another towards the northern defense line, and then find the witch and let her continue to send the heavenly demons to death one after another......

If there is civil strife today, some of the hundreds of millions of troops will definitely kill each other, so the amount of tasks will be reduced......

"You better do it yourself, in order to protect Zhongzhou, I asked for my life to form an army, but so many people died tragically under the butcher's knife of the Heavenly Demon, I am responsible for their wives and children......" Dongchen directly refused.

"Thunder Boy...... You didn't say that at the beginning, did you look at those people..."When the head of the Nine Xuanzong pointed into the distance, he was very embarrassed to find that there were still people here and there, all of whom had already evacuated.

"At the beginning of the war...... I have already asked the people to evacuate, and when I also left for Nanling Kingdom to look for those elders, I also asked several other elders who trained the army with me to inform you of the preparations for battle...... Dong Chen's eyes fell on the two elders who had been rescued by him.

"How the two of you fought bloodily in Nanling Kingdom, you should know the situation of the Heavenly Demon very well, and it is precisely because I myself know the situation of the Heavenly Demon that I will volunteer to be this commander, but ......" Dong Chen let out a long sigh.

"You really disappointed me, I fought bloodily for three days and three nights, millions of troops fought to death, and you haven't even seen a single reinforcement, now that the defense line is lost, and the heavenly demons have entered the interior to slaughter, you only think of resisting, it's too late......," Dongchen said with some sadness.

"Since you think that you can fight against the Heavenly Demons, go by yourself, I can't do anything about it, I am ashamed of the trust that those soldiers have placed in me, I could have taken them to hold the line, but...... Alas......" Dongchen sighed, turned around and disappeared as he spoke.

Leaving everyone in the five great sects to look at each other, Dong Chen ran away, and they could really only ask for more blessings......

Dong Chen said that he still had a responsibility, ignoring the situation here, and letting the five great sects face the Heavenly Demon Army by themselves, which was obviously just a pretense.

Dongchen does have a responsibility, a responsibility to train troops, and a responsibility to keep more people......

Without Dongchen's help, the army of ordinary people would not be able to organize, and without a larger-scale war, they could only do everything they could to force the Heavenly Demons back again and again, or be forced back by the Heavenly Demons again and again.

After all, whether it is the empty city, the Yin Netherworld Sect, or the Tianchi Sword Valley, they don't want to become the next Kunlai Lake and become a lost dog.

They must try their best to even stick to the sect you leave, which can buy Dong Chen a lot of time, which is enough time for Dong Chen to mobilize ordinary people, and enough for Dong Chen to build a more impregnable defense line in the north.

With them, you may delay time, Dongchen has more time to train, and when the time comes, they will have a way back, and when they are already like lost dogs, they can only shrink when they are beaten, and when they encounter the northern defense line, they will work harder when they finally heat up and shine......

It's just that if you want these guys to contribute, Dongchen has to find something for them to do......

This first batch of troops has been consumed, and the witch will have a second batch as soon as possible, maybe the number will be much less, but it is enough to train the troops.

Dongchen not only has to train the army of ordinary people, but also has to let the cultivators do their best, so that they will finally unite as one......

Dongchen left, but did not return directly to the camp, where the basic things are now taken care of by Li Chunyang and Yanjun, what Dongchen has to do at this time is to go to the northern defense line to have a look, and directly open up a place there that can be used as a battlefield fortress

The other is to create a terrain that is easy to defend and difficult to attack......

With his previous experience, Dong Chen was sure that his defense could be said to be difficult to break through, but the Heavenly Demon Army could bypass his defense and attack from other directions......

Dong Chen wants to turn the northern defense line into a funnel, and he can only fight head-on with him, otherwise he will be bypassed by the Heavenly Demon army, even if there are many cultivators joining forces at that time, I am afraid that the Heavenly Demon will find a loophole.

Dong Chen left the ruins on this side, and flew directly towards the north, where it was, and now in addition to being a pure land, half of the territory of the entire Zhongzhou has been ravaged by the Heavenly Demon Days......

When Dong Chen rushed to the north, the people here didn't even know anything about it, but Dong Chen didn't plan to alarm them, the main reason he came here was to build defenses.

Transform the surrounding mountains into a breakthrough formation that is best suited to sharp knives......

"It seems...... I have to shake the mountains a little bit......" Dongchen said secretly, taking out the sorrow of frost, wanting to move mountains and reclaim the sea, it was a little difficult for Dongchen, but it was not so difficult to change the way......

Hollow out the entire bottom of the mountain, and then move it directly to the location where he wants to land......

Although this is a bit of a huge amount of work, there are five major sects in front of him, and Dongchen can have a lot of time here, making the battlefield the most suitable for him, and at the same time, it is also the formation that can play the greatest crisis in the future.

Dongchen just thought about how to do it......

These mountains were moved directly from the outside of the city by Dongchen to the city, and many people's houses were directly bulldozed in the places where they passed......

Ordinary people don't know what's going on, and they think that there was an earthquake and the whole mountain is shifting......

Dongchen moved the mountain according to the direction of the Nine Palaces, surrounded by mountains, without any dead ends, and it was arranged from low to high.

Dong Chen tested his defense range a little, and if the main defense was placed directly above, it could almost envelop the entire mountain......

However, this defense can only be used in the end, and his main thing is to resist the impact of the Heavenly Demons, in case the defense line is directly overwhelmed......
