The undead will become weak during the day, and the coalition forces will definitely attack when the undead are weak. If Li Ziyu wants to win, he must use the strategy of dragging out the attack, delaying the opponent and prolonging the battle time. When the sun sets and night falls, he can counterattack.

As for the decisive battle with the opponent tonight, it is at night anyway, and the opponent has just arrived and is in a tired state, so the chances of winning are very high.

It does sound attractive, but if you think about it more deeply, you will know that it is not very realistic.

The coalition forces were not stupid. They deliberately kept a distance of ten kilometers. The undead under Li Ziyu were mainly skeleton undead. Although other types of soldiers were strong, their numbers were insufficient and they could only serve as secondary output or auxiliary positions.

With the skeleton undead's speed, they can be deployed on a large scale. When they arrive at the destination, everything is ready. They can even set up a large number of traps and wait for the undead to come over.

That's not a decisive battle, it's a delivery of food.

Especially the coalition forces that came this time, they are the elites of various races, with all kinds of soldiers, including long-range, melee, cavalry, magic, and priests. It is very comprehensive and not as simple as the previous battles.

Li Ziyu thought about it for a long time before he realized that if he wanted to win, he had to drag the game out, completely destroy the opponent's momentum, and make the soldiers tired, so that he could achieve the final victory.

Seeing that Li Ziyu was determined and unable to be persuaded, Zhang Peng reluctantly gave in and let Li Ziyu and 100 elite heavy hammer skeleton warriors enter the mole fortress.

The space inside the Ratman Fortress is relatively small, and the elite Hammer Skeleton Warriors are too large. In order to transport them, they have to bend over and lie on the ground.

After Li Ziyu entered the fortress, Zhang Peng activated the fortress and rushed to the intended location along the underground passage.

In order to contact the surrounding tribes, Zhang Peng has never been idle. He has dug a lot of tunnels underground. The tunnel leading to the coalition camp was also dug long ago, and the speed was very fast.

"Boss, we're here." Zhang Peng came to Li Ziyu and said to him.

"Okay, you wait here for me, I'll be back as soon as possible." Li Ziyu patted Zhang Peng and said.

Zhang Peng plays a very important role in this operation. If something goes wrong on his side, Li Ziyu will be in real trouble.

Zhang Peng nodded after hearing this.

Ten elite heavy hammer skeleton warriors had already left the Ratman Fortress and headed to explore the exit. According to Li Ziyu's request, the exit was very hidden, behind a large rock. At night, the exit was covered by the shadow of the rock and could not be found without careful observation.

The entrance to the cave was not very big, and could only accommodate two people at most. When Zhang Peng got the news, he was very puzzled. With such a big entrance, the elite Heavy Hammer Skeleton Warriors could not get out at all. He also couldn't figure out what Li Ziyu was going to do.

After determining the exit, Li Ziyu ordered all the elite Hammer Skeleton Warriors who followed him to be on guard, while he himself walked towards the cave entrance and climbed up the sloping earthen slope.

After exploring and observing for a while at the entrance of the passage and confirming that there were no coalition scouts around, Li Ziyu carefully crawled out, stuck to a stone, hid in the shadow of the stone, and looked out. From his position, he could see a fire in the distance, which was the coalition camp.
