"It seems that everything has to be used up now."

After finishing speaking, Zhao Mo quickly walked to the rolling log device, stone beating device, and hot oil device next to the camp.

The iron ore and coal resources required for advancement are 40 each.

【whether? 】

【Yes! 】

"There is still an advanced operation? Isn't level seven full?"

Zhao Mo looked at the hot oil device in front of him that had already reached full level, but it seemed that it could continue to be upgraded, as long as he clicked on this advanced step, he could continue to upgrade.

Zhao Mo curiously checked it with the invincible system.

[System Query: The log-rolling device, rock-pulling device, and hot oil device in the tower defense camp are divided into seven levels.

Each level can be advanced after reaching the full level, but the resources required for the advancement will be much more than the original level. 】

"There is still this operation?"

Zhao Mo curiously clicked on Advanced, intending you to see what it will look like after Advanced.

[Sorry, due to your lack of coal mine resources, the advancement failed! 】

Zhao Mo checked his remaining resources, and suddenly found that the current resources were suddenly reduced by so much.

[The system is querying for your remaining resources:

Host: Zhao Mo

Iron ore resources: 80 points

Quarry resources: 18 points

Coal resources: 30 points

Petroleum resources: 8 points

Wood resources: 0 points

】

At present, there is no way to upgrade to a higher level with such a small amount of resources.

"In this case, let's use these to deal with these monsters first!"

Zhao Mo pointed to the group of monsters in front of him that were still madly rushing towards the camp.

Soon countless flame balls were fired from the camp's city wall to attack these monsters.

There are also many rolling logs falling from the city wall, hitting the heads of the monsters who are trying to climb the city wall, and successfully repelling these monsters wave after wave with headshots.

The stone-pulling device is also slowly working on the side. The huge stones piled up are slowly getting bigger and bigger. They are quickly launched from the trebuchet on the side and smashed towards the monster group outside the camp wall. past.

But even so, it is difficult to resist the large-scale attack of the monster army.

"Damn it, there are too many planes for this group of monsters!"

Zhao Mo had no choice but to take out an elemental stone in his hand.

"It seems that we have to waste another one now!"

After finishing speaking, Zhao Mo picked up an elemental stone in his hand and used it to activate the [Seven Star Sword Formation].

As the energy of the elemental stones was slowly poured into the cards of the Seven Star Sword Formation, a huge assembly protective cover slowly covered the camp above the open space of Zhao Mo's camp.

The monsters outside the protective cover were instantly cut off by a huge barrier, and all of them reached the protective cover like moths to the flame and were wiped out.

Due to the great power of the Seven Star Sword Array, it was difficult for monsters from outside to attack the camp.

Slowly, the monsters who were in the camp before were almost consumed.

"Huh~~ I should be able to resist this time!"

Only then did Zhao Mo take a deep breath, and his whole body slowly relaxed.

[00 hours: 10 minutes: 53 seconds until the end of the second wave of monster attack in the tower defense world hard mode level]

With 10 minutes left, the second wave finally got stronger.

But just when Zhao Mo was about to wait for the end, due to the crazy attack of the monsters outside the camp, the seven-star sword array outside the camp slowly began to have cracks again.

"Mistgrass! It won't be so bad, will it?"

Zhao Mo's being attacked by these monsters one after another made him feel bad.

At first, they thought they had successfully resisted the second wave of attacks, but they didn't expect that the Seven Star Sword Formation would break out of a small crack so quickly due to too many monster attacks.

Zhao Mo looked nervously at the crack, and then stared at the countdown on the invincibility system.

[00 hours: 03 minutes: 53 seconds until the end of the second wave of monster attack in the tower defense world hard mode level]

As time passed bit by bit, these monsters were still attacking the crack.

Suddenly the crack became bigger, and many monsters rushed towards Zhao Mo's camp from the crack.

"Hoohoho~~"

Many monsters let out low howls, resounding over the entire camp.

Zhao Mo couldn't help but sweat in his heart, this time he really couldn't resist it.

[00 hours: 00 minutes: 00 seconds until the end of the second wave of monster attack in the tower defense world hard mode level]

[Congratulations to the host for successfully resisting the second wave of monster attacks in this difficult tower defense survival level! 】

As the countdown of the invincibility system ended, the monsters that were still emerging in a steady stream quickly retreated towards the rear in an instant.

It didn't take long for the outside of the camp to become empty, without any shadow of monsters coming.

Before Zhao Mo had much time to breathe, the time for the last wave of monster attacks began to count down.

[00 hours: 30 minutes: 59 seconds before the last wave of monster attack in the tower defense world hard mode level]
