The success rate of digging up the levee is about 70 percent, and the success rate of causing flooding is 80 percent.

Standing on the embankment, Chen Gu calculated in his heart.

If the plan succeeded, there was a 30% chance that he would destroy the level 9 city in one fell swoop.

And this thirty percent chance is enough for Chen Gu to bet on this.

In the past few hours, Chen Gu kept filling in all kinds of details for his plan this time.

Seeing that the plan is getting more and more complete, Chen Gu's judgment on the success rate of the plan is also constantly improving.

Now he was half sure that he would rush through the gates of that level 9 city.

Just as Chen Gu was considering the details of the plan, he suddenly heard the sound of a horn on the water.

Chen Gu raised his head and looked in the direction where the voice came from.

It was found that a thick fog had risen on the lake at some point.

A huge wooden ship emerged in the thick fog.

The wooden ship seemed to have been pieced together from the fragments of seven or eight ships.

On the hull of the ship hung many skeleton soldiers with aquatic plants on their bodies.

When they saw Chen Gu standing by the lake, those skeleton soldiers also raised their weapons in their hands.

It can be seen that they are the undead troops in the lake.

However, Chen Gu could tell at a glance that they didn't belong to any undead legion, they were wild undead.

After seeing the ghost ship appear, Chen Gu was not in a hurry to leave.

Instead, he beckoned, and thirty holy light magma immediately appeared beside him.

Chen Gu didn't mean to let the Holy Light Magma rush into the lake, he just asked them to wait by the lake.

If this ghost ship didn't mean to go ashore, then Chen Gu would ignore them, and if they did, these holy light magma would just be able to kill all the skeleton soldiers sent out by the ghost ship.

After releasing the holy light magma, Chen Gu sat aside.

Now he needs to replenish his mana.

Because the next thing he has to face is a level 9 undead city.

If there is a slight mistake in mana, it is likely that the situation will change.

As for the ghost ship in front of them, if they hadn't made a move on Chen Gu, then Chen Gu wouldn't have touched them at this time.

But Chen Gu never thought that this ghost ship was not attracted by him.

Instead, he was attracted by the fish in Chen Gu's hand.

Chen Gu has been fishing here for a while.

Because a small percentage of the fish they catch are dead, their death aura attracts ghost ships.

This made the ghost ship willing to come over and take a look.

As a result, as soon as they arrived at the lake, they saw Chen Gu standing on the shore of the lake.

So it's actually a complete accident.

But they have already faced the situation in front of them, and the ghost ship will not be surprised or not.

The skeleton soldiers hanging on the side of the ghost boat jumped directly into the water and swam in the direction of Chen Gu.

"Fire Spirit Crow, Blood Shadow Wolf, get ready for battle, the Ghoul Vine continues its own business, Holy Light Magma, let those skeleton soldiers go ashore and then fight."

Chen Gu made a decisive decision, and at the same time, he also contacted the corpse eater, where he judged the situation of the embankment at this time.

If the ghost ship dies by itself and jumps in front of him again, then Chen Gu will decide to solve the ghost ship first.

As for mana or something, he could have rested here a little more.

Anyway, the undead city is over there, and he won't run away, and the efforts he made before won't be wasted.

As for not being able to defeat the ghost ship, it's impossible.

Chen Gu just couldn't get into the water, but he could still defeat such a ghost ship that wasn't too big.

Just as Chen Gu was confidently looking at the ghost ship in front of him, he suddenly found that in the thick fog, at least ten more such ghost ships had appeared.

The situation of each ghost ship is distinctly different.

Although all ghost ships are pieced together from the fragments of the ship.

But the size and number of these ghost ships are beyond the ghost ship that came out before.

On top of that, it's no longer just skeletons that appear on the ghost ship, but also ghosts and water-soaked walking corpses.

It seems that this time Chen Gu's actions did not lead to a ghost boat, but to all the ghost boats in the lake.

"The troops retreated, and the ghoul vines left underground."

As soon as he saw the situation in front of him, Chen Gu made a decisive decision.

At the same time, he also counted the number of ghost ships here.

There are nearly 1,700 undead in total.

Although there are no more powerful undead in it, this can already be regarded as a strong undead team.

If Chen Gu's subordinates were all concentrated here, and then led them all to the shore, there would be no problem, he could fight.

But in the current situation, Chen Gu's troops were not at hand, and he didn't have time to think about fighting these undead.

A little bit of undead, Chen Gu may be able to deal with it casually.

With so many undead, Chen Gu was not embarrassed at all when he retreated.

When Chen Gu retreated, he didn't forget to take away a few fish that he had just caught.

That's the crux of the plan.

When Chen Gu retreated, the Holy Light Magma did not leave.

As minions, they either fight to the death or disappear half an hour after the battle is over.

Chen Gu didn't plan to take them away, so he let them fight with these undead, and Chen Gu also wanted to see if these undead had the ability to fight after leaving the lake.

Those undead don't care what Chen Gu thinks.

When they saw Chen Gu retreating, they knew that they had discovered the enemy.

So the undead quickly rushed to the shore, and in a few moments, a large number of undead jumped ashore.

The Holy Light Magma was not afraid of anything because Chen Gu's troops left, and in the face of the undead, they took the initiative to meet them.

They use Holy Light Bullets against the farther undead, and against the closer ones, they use the power of magma to attack.

Even in the face of multi-faceted undead attacks, they were not afraid.

The undead attack fell on them, and they didn't care.

Even if they were surrounded by the undead in the end, and when they were beaten to death by the undead, they would explode directly, and they would have the same idea of retreating at all.

Chen Gu retreated while looking at the undead.

He noticed that none of the undead could get three hundred meters away from the lake rock.

As soon as they reach this distance, they will stop their pursuit.

Lingering on the edge of this distance for a while, and finally retreating all back into the lake.

After the retreat of the undead, Chen Gu was not in a hurry to go back, he waited for nearly an hour at a distance of about three hundred meters outside the rock edge, and it was not until the dense fog on the lake surface cleared that Chen Gu returned to the place where the Holy Light Magma had fought before.

Although the undead at this time retreated, they did not have the habit of tidying up the battlefield, and the chaotic battlefield remained in place at that time.

As soon as he arrived here, Chen Gu could see at a glance that all the previous thirty Holy Light Magma had been killed in battle, and at the same time, there were nearly three hundred corpses of undead left here.
