Chapter 809: Undead army crossing the river

Because the two entrances are relatively large, everyone is busy for more than ten hours, from day to night.
During these ten hours, they moved almost all the materials that could be obtained within five kilometers of the cave, making the two entrances of the cave look like artificial bunkers.
After it was completely dark outside, the Lu Army let the snow bears and elves all enter the cave.
This is because the scouts he sent outside have not returned until now. The Lu Army doesn't know what the undead creatures are like, and whether they cross the river.
Just when the Lu Army was about to send a new scout troop to take a look, a few antler eagles finally flew back with the elf scouts.
From their mouths, the road army learned that the undead creatures had arrived on the other side of the river, were checking the surrounding conditions, and were preparing to cross the river.
And this group of undead creatures are more than they have been encircled and suppressed before, more than 100,000 is for sure, even the rarest bone dragon army has about 5,000, it seems that 80% of the undead creatures in the frost forest have arrived here.
This situation caused headaches for the Lu Army. The opponent had at least hundreds of thousands of troops, and they had nowhere to run, so they had to defend for three days. They had no chance of winning.
Fortunately, their defensive location is a solid cave, and the air force of undead creatures can be ignored. In fact, the enemy they have to deal with will be 20% less.
But even so, the chance of winning this defensive battle is still not high. After all, the true power of the Abyss Demon King has not been used yet, and Lu Jun always feels very suspenseful in his heart.
Therefore, in this situation, the Lu Army can only prepare the elves and snow bears to meet the enemy, and place 40% of the troops in each of the two gates, and reserve 20% of the troops for backup, where support is needed.
However, what the Lu Army did not expect was that the undead creatures did not attack that night.
Because after a day of washing, all the bones in the river were washed away, and the river regained its depth.
Although the undead warriors can cross the river from some shallow places, there is only one road there after all, which cannot accommodate so many undead warriors.
If they walk slowly in line, it is estimated that it will take a day or two for them to get through.
This situation puts the undead creatures in trouble. They don't have so much time, and there are not so many skeleton fighters to fill the river. They can only let the air force transport their fighters one by one.
You know that they have hundreds of thousands of ground troops, so it is not easy for air troops of less than 20,000 to transport hundreds of thousands of ground troops.
Forget it if it's just a thinner ghoul, and the gargoyle can still be transported.
But they also have fat plague ghosts and heavier meat grinders. These two things can't be moved by gargoyles at all, they can only be transported by bone dragons.
So just to transport troops, the undead creatures spent one night, and they did not transport all their troops until dawn.
The Abyss Demon King was very anxious when he saw this situation, but he could only wait patiently, after all, these undead fighters were needed to attack.
After all the troops have crossed the river, the undead creatures cannot attack directly, because they still don't know where the road army and the elves are hiding.
Moreover, it is daytime, and their combat effectiveness will be greatly weakened, which is not conducive to combat.
In order to maintain the fighting power of his subordinates, the Abyssal Demon King had to hide the undead warriors in the nearby woods first, planning to attack again at night.
The road army hiding in the snow bear cave also learned of the farce that happened when the undead creatures crossed the river through the scout, which made him laugh.
Although waiting for nothing all night and wasting a lot of time, the Lu Army was still satisfied with the result that the undead creatures had not attacked yet.
Because in this way they will continue to have time to strengthen their defenses and increase their chances of winning.
Although the surrounding materials have been cleaned by them now, they cannot search too far away.
But they can also dig pits to create traps. You must know that digging pits doesn't use so much material.
So at dawn, knowing that the undead creatures would not come in a short time, the Lu Army sent the snow bears and elves out again, and let them start digging pits around the cave, which was a large pit several meters high.
Even if these traps cannot kill dead creatures, they can limit the offensive formation of dead creatures, which is enough.
In the following day, Lu Jun and others dug hundreds of large pits around them, and they were all hidden with hay and snowflakes, making it difficult for undead creatures who like to act at night to see them.
When it got dark, the Lu Army ordered the elves and the snow bear to hide again. They should rest and rest, be vigilant, recharge their energy, and wait for the enemy to arrive. The only requirement was not to make any noise.
Because Lu Jun felt that the undead creatures didn't know their location and were still looking for it slowly.
The snow bears have such a large territory, and the caves they are in are inconspicuous, and it is not easy to find undead creatures.
As long as they can continue to drag the time, the situation will be beneficial to them, because it has been a day and a half since the tree of life was planted, and there is still a day and a half to plant the tree of life. When the legendary real-time mission is completed, Lu Jun I'm not afraid of the undead army...
At the same time, the abyss demon king on the other side saw that the sky was finally dark, and immediately let the undead creatures hidden in the woods get up and march towards the snow bear's territory.
Because they didn't know the location of the road army and others, they were spread out, looking for clues around.
But they are more than four hours away from the road army, and the route they are looking for is a little pouring, causing most of the night to pass, and they still get nothing.
This situation made the Abyss Demon very anxious and regretted secretly.
Because it forgot to let the bone dragon and gargoyle fly out to find someone during the day, it wasted a lot of time, otherwise they might have found someone now.
But regret alone is useless. The Abyss Demon can only continuously expand their search range, maximize their formation, and conduct a full-scale search.
However, the sky was still snowing at this time, and it was covered in white everywhere, completely concealing the traces of the activities of the snow bear and the Lu Army and others.
If there are no markers, it is estimated that these undead creatures can't distinguish east from west to north, let alone find the cave of the road army.
This situation lasted until the day, when the undead army coiled around in the snow bear's ground and became dizzy, not even knowing where it was.
Fortunately, after several hours of hard work, the Bone Dragon Army with a little bit of IQ finally locked the location of Lu Jun and others and reported it to the Abyss Demon King.
That's because Lu Jun and others collected all the scattered materials around, so that some of the bone dragons found a flaw, flew a dozen times along the side, and found the snow bear cave...
