Number One Dungeon Supplier

Meantime, when all the commotion was happening in the Northern Capital and the newly revealed Undercity, the East and the West had their own problems to handle. The Demon Rat Army who had recovered from the initial shock attack after Day 1 had been pushing aggressively against the other two sides. They were dying to get to the surface and all they needed was just one rat to go through for the plan to work.

As long as one Demon Rat Soldier was able to go through all the defences and remained unscathed, they have the opportunity to expand into the East and West regions when time permits.

This was because each one of the soldiers had been ordered to carry a bunch of seeds with them and there were none other than the Demon mutant seeds which they were grown from. In fact, the Demon Rats were curious whether those Demon mutant seeds would eventually grow into something different and yet similar in nature to them when grown in soil that was not from the Northern Region.

There were some scientists who theorised that it was because of the difference in spiritual soil that could either make or break the mutant seeds' growth. There was always a possibility that the mutant seeds could only grow in the Northern Region but there was no harm in trying it out in the Western and Eastern Regions and see if they could grow the same as well.

Yet, all those attempts by the Demon Rats regardless of their aggressive retaliation had not been successful in allowing even one Demon Rat to pass through. This was mainly because Qiu Yue was personally behind the creation of the defences as they went into Demon Rat territories.

Because of their large army which included their rat abominations, the Demon Rats would require tunnels that were large enough to not only allow at least rows of Demon Rats to pass through but high enough to allow their Abominations to slip through as well. Not to mention, they needed enough space for future developments and thus did not skimp on the digging process.

But they did not expect that it would be their downfall as it was used against them.

While the basic foundation of maintaining a tunnel had been deployed throughout the entire area, there was nothing but debris, rat waste and broken equipment that littered the place. They did not foresee any assaults through those tunnels since the Demon Rats assumed they were the only ones who were privy to this particular plan of theirs. They never knew that Jin and the System had been monitoring them closely so that they could swoop at them all at one go. That was also the reason why they decided to be greedy and split their resources to move into two regions at one go. However, all of these decisions were previously made by the Scholars and the Demon Rats had to handle the consequences of their mistakes. Else, they believed that if they concentrated on just one region, their Demon Rat armies would more or less defeat the defending forces easily with sheer numbers.

So, with the tunnel empty, Jin's minions had the upper hand since they have a Magical Constructor by their side deploying tactical walls and defences that allow them to throw greater firepower at the Demon Rats. This was also one of the reasons why Jin had been monitoring the battles in this Great Demon War.

Unlike the Demon Rats who apparently have numbers greater than them by a huge margin, there was only a limited number of troops that Jin possessed. Even with the System's omnipotent contract System and access to the Black Market to get more 'NPCs', there were only that amount of people the System could hire due to its limited processing systems.

And also, grabbing too many contracts off the Black Market could cause suspicions to other people from other universes and it was best not to deal with them unless necessary.

Else, Jin might have to handle a threat that he was not expecting and so far, he was the changing factor for the world and none had yet to come to his world for now. Still, Jin knew he had to be careful since his world could be invaded for no reason especially after the Dungeon Supplier heard how Derek's world turned into a permanent Zombieland.

So with the defences erected within the tunnels, Both the assigned armies in the East and the West were able to fight and prevent any leakages from going through. Some of the Demon Rats even used invisibility or high speed runners to break through the defences but Qiu Yue had assigned a few of her Beavers with special powers so that those tricky Demon Rats were able to be detected and captured. There were gadgets that allowed the detection of invisibility spells as well as traps that could stop the high speed runners in their tracks like gravity counters which break the runners' momentum as they trip and fall (while being stuck to the ground until they were killed.)

And with the help of those beavers, Qiu Yue was able to move from one side of the Farming World to the other side ensuring that the defences were solid enough to not only hold the front but also give cover to those who were injured and provide defensive fire with the automatic cannons that were built along with it.

Yet, that did not mean the East and West frontiers had it easy as the Demon Rats had a massive horde rush and those defensive fortifications were used as buffers to slow down the horde since the Beavers and Qiu Yue could detonate them, destroying a portion of the massive horde to slow them down.

After which when they regain their ground, the Empire Building Sub System User would then rebuild the very same defensive walls again to hold the attrition line. It might be tedious for the forces but when they had the luxury and advantage of the tunnels at their side, especially against overwhelming numbers, it was best to use that perk as much as possible.
