The Frost Dragon was so large that Bright swapped from Astro to a silver Pegasus in the air and landed behind a mountain pack near the cave.

The whole process was not discovered by the elven soldiers, and even if they did, they could not have connected the silver Pegasus with the undead army, and could only think that it was a silver Pegasus knight of their own.

Retracting the silver Pegasus into the armor card, Da Liang quickly approached the cave entrance with the help of the hidden terrain, and when he couldn't hide, he directly used "stealth" and then kept a low speed and walked towards the cave entrance.

Since the Forgotten City needed support, and there were constant teams of elves coming out of the cave, the deadwood warriors guarding the entrance of the cave did not seal the entrance to the cave, but stood on either side to leave an easy path in the middle.

This also provides great convenience for Daliang.

He carefully dodged the elven soldiers who walked by, and then took advantage of a gap to burrow into the cave.

The entrance to this cave looked relatively small, but Da Liang didn't expect it to be so large inside.

It's a miniature underworld.

And there's no telling of what this is like in the realm of death at all.

A small stream meanders, and everything is green.

The green meadows, the dense woods, and the huts built on the branches.

The invading elves have gradually transformed this place into a suitable environment for the elves to live, looking at the clusters of tree fruits on the top of the trees, the elves plan to turn this place into a food supply place to reduce the energy consumed by the transportation of food through the dimensional space.

At the same time, this elven army is also ready to be here for a long time.

As long as they can transform more green space and produce more food, they can send more and stronger armies, unicorns and dragons.

It seems to underestimate the Elves' determination to occupy the Forgotten Hills.

Once this mountainous area isolated from the outside world is transformed by the elves into an environment suitable for the elves to live, it can become a bridgehead for the Dream Realm to attack the realm of the dead. In this kind of precipitous terrain, the Sea of Bones tactic, which the undead are good at, cannot be used, as long as the elves can hold the Forgotten City, the undead can only enter the Forgotten Hills by throwing small troops into the mountains through some paths.

And in the competition of small forces, the undead are definitely not the opponent of the elven race.

Once the elves have managed the Oblivion Hills and secured them, they can threaten the Sighs, an important city in the Realm of the Dead, at any time.

Da Liang didn't expect the Forgotten Hills to have such an important strategic position in the Dream Realm, which also meant that if his army wiped out the elven defenders here, it was likely to encounter a crazy counterattack from the Dream Realm.

I didn't expect it to be a hot potato here.

As for abandoning this place after completing the mission after laying down the Forgotten Hill, Da Liang also thought about it just now.

If this is a single mission, it is easy to do, but I am afraid that this is a continuous territorial mission. As soon as you walk on the front foot, the elves reoccupy the place, and it won't be so easy to fight again.

But no matter what the future tasks are, first find the plane teleportation array and eat the elven army here.

Even though the Forgotten City is summoning reinforcements, there are still a certain number of defenders in this cave, and they are all promoted troops, not many of them, and they are all very powerful. Especially the level 6 elf archer who has been promoted by the elf shooter, the double shot skill doubles their attack ability, which is a very tricky ranged class.

The dense vegetation in the cave gives Da Liang a lot of hiding environment that can be used, and he combines "stealth" and "Nicole's jump" to go deeper into the interior of the cave little by little.

Then I found this dimensional teleportation array in the innermost layer of the cave.

It was an indestructible and uncontrollable permanent dimensional teleportation array, standing on a mountain wall, about ten meters in diameter, with red ripples shaking on the surface.

There is a small defensive camp in front of the teleportation array, with 500 elf archers stationed in it, plus the elven soldiers scattered throughout the cave, and an unknown number of elven heroes, it is not easy to capture here.

At least in an environment where there are elves everywhere, it is impossible for Da Liang to set up a necromantic portal without being discovered, and let his army in the sulfur mine cave rush in.

If you lay a necromantic portal outside the cave.

It takes time to attack the cave guarded by the Deadwood Warriors, and it takes time to attack the Plane Teleportation Array guarded by the Elves.

And is there an elven army on the other side of the plane teleportation array?

If there is a steady stream of elven armies rushing in on the opposite side, then it will become a war of attrition, and Da Liang has always avoided the occurrence of a war of attrition, and he can't afford to fight a war of attrition now.

The only way to go through the plane portal is to see if there is a chance to lay a necromantic portal over there.

Da Liang quietly entered the camp guarded by the elven archers, and then crawled out of the corner of the dimensional portal.

A more natural scent hits the nose.

The sun was shining brightly on the clear sky, and there was a large forest with no end in sight, and from time to time a hill protruded from the beautiful world.

Da Liang found himself on the mountainside of a hill, with a cliff behind him, a gentle ridge in front of him, and a bluestone paved road that stretched into the forest below, and about fifteen kilometers away he could see an elven city.

It looks like an eighth-level city.

Da Liang then spotted a group of Pegasus Knights at the top of the hill, who were supposed to be the sentinels in charge of monitoring the teleportation array.

Da Liang quickly stayed invisible and stood against the cliff wall, and then continued to use the telescope to quietly observe whether there were any other elven troops around.

This hill is surrounded by cliffs on three sides, only the ridge in front of it is slightly gentle, and after the elves have repaired it, it can barely allow the army to march, but if it is attacked from the bottom up, it will be very difficult, the troops will not spread, and the long-range troops will also have a serious penalty in range due to the height difference.

The defending troops can occupy the top of the mountain and easily resist the attack from below, of course, provided that there are sufficient supplies and reinforcements.

The elves' defense against this mountain is weak, so they can take down this side of the plane teleportation array first, and then enter through the plane teleportation array counterattack, and attack from behind that elf to take down the camp with perfect defense capabilities.

Finally, use the camp as a base to attack the elven army in the cave, as long as you occupy this cave, you can cut off the logistics supply and soldier supply of the Forgotten City, and seal this elven army in the Forgotten Hill.

The result is the same as the strategic plan developed by KUKA. With nothing to eat, the elven army trapped in the Forgotten City has only two options: surrender or starve to death.
