Following the rudiments of the aviation warships of the old Wei period, Luban created a new and upgraded version of the aircraft carriers, each with a capacity of 5,000 people. Because of this great feat of innovation, Lu Ban was promoted to master of Karakuri by Jixia Academy.

In order to adapt to the harsh wind and snow climate in the far north, Di Renjie and Lu Ban decided to install a device for the aircraft carrier that can withstand wind and snow after discussion.

Lu Ban led a transformation team of hundreds of people, and after ten days and ten nights of continuous operation, each aircraft carrier was finally equipped with a wind and snow cancellation device.

"Master Luban, thank you, without your ingenuity and hard work, the fleet would not have been able to enter the north so quickly." Di Renjie said with emotion.

"Your Excellency, Commander, you have a good reputation, and this is my duty." Lu Ban smiled humbly.

Now that the problem of aircraft carriers being protected from wind and snow has been solved. Then, the arrangement of the battle plan is imminent.

However, when Di Renjie wanted to invite the army of the Tang Dynasty to go north together in the name of the commander-in-chief of the Demon Punishment Alliance, he was stopped by Master Mozi.

Master Mozi said: "We must not invite the Tang army to fight together when we send troops north. If Datang is on the side of the demons, before joining the war, they will leak the timing and plan of our battle to the demons. Then at that point, we will be in a huge passivity. Therefore, invitations could only be written to them at the end of the war. ”

"Mr. Mo, what if the Tang Dynasty discovers our intentions when we send troops?" Di Renjie said.

"So, we're going to hide our whereabouts anyway. Let the reservists who stayed in the various realms assemble on the border of the Tang Dynasty and make a posture of pretending to attack them. Datang desperately wants to preserve its strength, and between us and the demons, the camera acts. When they are alert, they focus on the reserves and have no time for other things. After that, our demon allied army quietly marched north at night. ”

"Mr. Mo is really clever, this trick is hidden from the sky and the sea, and the Tang Dynasty will be unable to prevent it, you can be said to be the Dinghai Divine Needle of our three armies." Di Renjie said.

After that, Di Renjie convened the specific deployment of the battle plans of each realm.

"It has been found that there are 300,000 soldiers in the base camp of the demon clan in the north, and there are 50,000 stragglers everywhere, a total of 350,000. The army has abundant weapons reserves and strong overall combat effectiveness, but their biggest shortcoming is the problem of physical supplementation. Because the northern demons mainly rely on food, supplemented by photosynthesis, to supplement their physical strength. If they start a war with us, it will inevitably accelerate the consumption of large quantities of stored food in a short period of time, and we will make a big fuss with the current wind and snow, which makes it difficult for them to use light and action. Therefore, the purpose of our current battle plan is to delay and attrition. With a small force, the main force that constantly harasses and lures them will continue to drain their physical strength until the time is ripe, and we will launch a general attack and annihilate them in one fell swoop. Di Renjie paused, and swept his eyes at the generals of the various realms, and found that they had no objections.

After that, Di Renjie continued: "All the Demon Killing Alliance forces are all dispatched, of which 400,000 horses are on the east road, and the other 400,000 horses are advancing on the west road, and the two roads complement each other and help each other. The remaining 50,000 horses are responsible for luring the main force of the demons and the dispatch of stragglers in front.
