Because the two holes are relatively large, everyone is busy for more than ten hours, from day to night.

In the past ten hours, they have moved almost all the materials they can get within five kilometers of the cave, making the two entrances of the cave look like man-made bunkers.

When it was completely dark outside, the road army let the snow bear and the elves into the cave.

This is because the scouts he sent outside have not returned until now, and the Lu army does not know what the situation of those undead creatures is, and they have not crossed the river.

Just as the Route Army was about to send a new scout force to take a look, a few Antlered Eagles finally flew back with the Elven Scouts.

From their mouths, the road army knew that the undead creatures had arrived on the other side of the river, and were checking the surroundings and preparing to cross the river.

And this batch of undead creatures is more than the previous encirclement and suppression of them, more than 100,000 is certain, even the rarest army of bone dragons has about 5,000, it seems that eighty percent of the undead creatures in the frost forest have arrived here.

This situation gave the road army a headache, the other side had at least 100,000 troops, and they had no place to run, so they had to defend for three days in a row, no matter how they looked at it, they had no chance of winning.

Luckily, they're defending in a sturdy cavern, so they can ignore the air power of the undead creatures, and they'll actually have to deal with less enemies than a half.

But even so, the chances of winning this defensive battle are still not high, after all, the true power of the Abyss Demon King has not been used yet, and Lu Jun always feels very hung in his heart.

Therefore, in this case, the road army can only let the elves and snow bears prepare to meet the enemy, and place forty percent of the troops in each of the two gates, leaving two percent of the troops for backup, where to support and where.

However, what Lu Jun didn't expect was that the undead creatures did not attack this night.

After a day of washing, all the bones in the river were washed away, and the river regained its depth.

Although the undead warriors could cross the river from some of the shallower places, there was only one road there, and there was not enough room for that many undead warriors.

If they walk slowly in line, it will take them a day or two to fully cross the line.

This situation puts the undead creatures in trouble, they don't have as much time and not as many skeleton warriors to fill the river, so they can only let the air force transport their warriors one by one.

You must know that they have more than 100,000 ground troops, and it is not easy for less than 20,000 air troops to transport more than 100,000 ground troops.

If it's just a skinny ghoul, the gargoyle can still be transported.

But they also have fat plague ghosts and heavier meat grinders, both of which can't be moved by gargoyles at all, and can only be carried by bone dragons.

So just to transport the troops, the undead creatures spent a night, and they didn't bring all the troops over until dawn.

The Abyss Demon King was very anxious when he saw this situation, but he could only wait patiently, after all, he needed these undead warriors when attacking.

After all the forces had crossed the river, the undead creatures could not attack directly, because they did not know where the road army and the elves had hidden.

Moreover, it is daytime at this time, and their combat effectiveness will be greatly weakened, which is not conducive to combat.

In order to maintain the combat effectiveness of his subordinates, the Abyss Demon King could only let the undead warriors hide in the nearby woods first, intending to attack again at night.

Lu Jun, who was hiding in the Snow Bear Cave**, also learned about the farce that happened when the undead creatures crossed the river through the scouts, which made him laugh out loud.

Although he waited in vain for a night and wasted a lot of time, the road army was still very satisfied with the result that the undead creatures had not yet attacked.

Because then they will continue to have time to strengthen their defenses and increase their chances of victory.

Even though they had cleaned up the surrounding materials, they couldn't look too far away.

But they can also dig pits to create traps, and you know, you don't need so many materials to dig pits.

So as soon as the morning dawned, knowing that the undead creatures would not be coming for a short time, the road army sent the snow bears and the elves out again, and let them start digging holes around the cave, and it was a large pit several meters high.

Even if these traps can't kill the undead creatures, they can limit the undead creatures' attack formation, and that's enough.

In the following day, Lu Jun and the others dug hundreds of large pits around the area, and all of them were covered with hay and snowflakes, making it difficult for undead creatures who like to move at night to see.

As soon as it was dark, the road army ordered the elves and the snow bear to hide back again, resting when they should rest, and guarding them when they should be on guard, the only requirement was not to make a sound.

Because Lu Jun felt that the undead creatures didn't know their location, they were still slowly looking for them.

And the territory of the snow bears is so large, and the cave where they are located is inconspicuous, it is not easy for the undead creatures to find.
