Although the army of the undead will have millions of extra reinforcements, their attack will be five days later, and the defenders will have plenty of time to prepare their ammunition.

The size of the Monster Arsenal is constantly expanding, and the Monster Workers are all working hard.

Several forests in the mountains were razed to the ground, and large quantities of timber were sent to the arsenal. Monster workers don't need any tools at all, and their innate skills make them fully capable of doing all kinds of work.

Five days passed quickly, during which the monsters were well stocked with ammo and many new weapons were added.

Next, all you have to do is wait for the undead to attack.

After receiving a million reinforcements, the army of the undead immediately became arrogant. Surprisingly, though, they didn't attack directly, but continued to be quiet and pampered, as if they were waiting for something.

The monsters were puzzled by this, but they were not too worried at all, but were happy because they had been given more time to produce weapons and ammunition.

Three more days passed, and after eight days of silence, the army of the undead finally launched its fourth large-scale assault on the Monster Fortress. The undead have a million reinforcements, and the momentum is huge.

As the army of the undead approached, the clear sky darkened again.

The enemies in front of them looked more terrifying than before, and there were more of them, but the monsters guarding the city wall were not afraid at all, because the weapons in their hands could be called divine weapons when dealing with the undead, and they were not afraid of more undead!

But what makes the monsters feel a little strange is that the clothes of the undead who rushed to the front are very strange. The guys were all dressed in a variety of raincoats, covering their whole bodies, and in front of their eyes was a layer of transparent plastic, which would not affect their vision.

Some of the undead are even more bizarre, even wearing large material belts directly on their bodies, and rain boots on their feet...

There are even more outrageous skeletons, holding a rusty machete in one hand and an umbrella in the other...

Dressed like this, the gray-white army of the undead in the past has become colorful, which is really funny, and the monsters naturally don't think so.

But Barr didn't think so, he sensed that things were not good, and he could only smile bitterly at this time, "Those guys can actually think of this trick too!" Absolutely! ”

The vanguard of the army of the undead was almost all wearing raincoats, draped in ribbons or tarpaulins, wearing waterproof glasses, some with umbrellas, and some with exceptionally large umbrellas, covering a group of small soldiers...

Needless to guess, Barr knew that the daily necessities were of human origin, and that the undead must have collected them in the towns they had conquered and used them. It turns out that the undead have been preparing these things during this period of silence. Looks like the Burning Legion is in trouble again this time!

After a few dull drums of war, the army of the undead finally began its fourth full-scale assault.

Countless undead, undead in waterproof gear, began to launch a fierce attack on the monster fortress.

At first, the monsters were unimpressed, believing that the weapons in their hands could shoot all the undead, because wasn't that how it was the other day.

However, this time it was different, the water shot out of the water guns in the hands of the monsters was all silently blocked by the waterproof equipment of the undead, and the former divine power of purifying the divine water could not be reflected at all!

This is a real problem!

Barr immediately sent the monster to ask Norton to come over.

Soon, Norton, dressed in a white riding coat, came to the monster fortress. When she saw that the undead who were besieging the city were all wearing raincoats, she was also stunned for a long time.

"That's... Those guys can still do this... Such! After a long time, Norton finally stammered in surprise.

Baal said with a grim expression, "Although the undead are very funny, they are very effective, completely blocking out the water. If we continue like this, I am afraid that we will be defeated. ”

"So, wouldn't it be okay for the monsters to break those waterproof suits with normal attacks?"

"But it's not a long-term solution, and it won't affect too many enemies. Can you add some sulfuric acid to the water to corrode the raincoats of the undead? ”

"Good idea, but it will take time to experiment, and it may even affect the effectiveness of the Purifying Divine Water."

"Without further ado, you hurry up and experiment, the current crisis should not cause our entire army to retreat."

Norton departed at once, in a hurry, and she was not at all sloppy now.

Barr looked coldly at the undead who were besieging the city, those guys had raincoats to protect them, and they were no longer afraid of the purifying divine water. Even if the "bomber" troops carpet bombed past, they would not be able to kill or injure them in the slightest. The bucket that falls from the sky does zero damage to the undead.

Of course, there are some cases where the undead are lucky enough to break their waterproof suits or umbrellas, and they can cause fatal damage to the undead, but those cases are pitiful and almost negligible.

Just when the monsters were on the verge of being attacked by the undead, Baal suddenly fell from the sky, and with a breath of great demons, he immediately burned all the undead in this area, such as raincoats and umbrellas.

Immediately, the monsters picked up water guns and fired desperately, drowning the undead. The undead did not have the super protection of raincoats, and when they were shot directly by the water, their bodies immediately smoked, and their mouths let out screams. After being shot a few more times, it turned into a pile of white bones.

The crisis in this area was solved, but everywhere else, almost the entire front, was in this crisis, and it was impossible for Baal to hold all of them. On a long front, he could only hold one of the points.

Baal ordered the monsters to break the undead's raincoats with normal attacks, and then attack with water cannons. Although this reduced the monsters' killing efficiency by more than half, it still barely blocked the surging attack of the undead.

In this case, the "high-altitude bomber" unit, as well as the barrel dropper unit and the water cannon unit, which used to be a strategic force, are now all useless.

In the end, the battle was thrilling, during which the undead attacked the city wall several times, killing a lot of monsters and destroying a lot of weapons, but in the end it was still saved by Baal.

The undead also seem to be unprepared, this time it was probably just an experiment, when the vanguard troops wearing waterproof equipment all fell, there were no waterproof troops behind, so they had to retreat.

But next time, I'm afraid that the undead will arm the entire army of the undead with raincoats, and if there is no good way to deal with it, the monster fortress will definitely be captured.

After the end of the fourth assault of the army of the undead, another three days passed.

Presumably, during this period, the undead must have been preparing for the fifth attack, and that attack is likely to be the final battle!

But fortunately, Norton finally succeeded in improving the purifying divine water, adding corrosive agents to it, and under the experiment, it was able to corrode the weak things, and if it was sprayed on the raincoat or umbrella, it would definitely be able to corrode it. Now, Barr doesn't need to worry.

But it wasn't that easy.

The Purifying Divine Water with the addition of corrosive agent has a corrosive effect, but at the same time, the medicinal effect of the Purifying Divine Water will also be corroded, and it only takes three hours, and the Purifying Divine Water with the addition of corrosive agent will not cause damage to the undead at all.

And that's not all, the hybrid corrodes the fragile wood. Most of the monsters' weapons are made of wood, the kind of material that can be easily obtained without money, as many as you want, and it is extremely easy to process, no one will refuse to use it. That's why the current contradiction has been created.

In this case, the service life of the monsters' weapons will be greatly reduced, and I am afraid that it will break down in less than a day.

Despite the above negative factors, fortunately they are all acceptable.

Since the effect of the medicine is only three hours, it is good to prepare it before using it.

As for weapons, then it would be good to replace them frequently.

The monsters hurriedly prepared for another day and a night.

Then, after four days of silence, the army of the undead finally launched a fifth major attack.
