Chapter 96: Upgrade! Upgrade! Upgrade!

Among all the monsters, Frost Soldiers were the most numerous, including those with shields, hammers, and blades. Counting carefully, there were actually seven different types of monster troops coming to attack the building!

"Kill them, charge!"

"Loot loot loot!"

"Let them taste the power of my scimitar!"

Before the monsters even reached the tenth floor, Xu Lang could hear their chattering shouts.

Although he had never heard this language before, he could somehow understand it inexplicably.

"Roar!"

A Frost Wolf leaped into the surveillance screen's view first, followed by a large group of Frost Ghosts flooding into the corridor.

Whoosh whoosh whoosh~

Three turrets immediately activated, with the heavy crossbow piercing through a Frost Wolf head-on, then the entire door became surrounded by monsters.

"Lang Ge, some dorms have already been breached, these monsters break through doors so quickly!" Wang Yazhi shouted repeatedly.

Xu Lang was sweating on his forehead and didn't respond.

The dorm door losing 5 durability points per second, who could withstand that?!

This is way too intense!

Without any hesitation, Xu Lang decisively chose to upgrade the dorm door.

Under the fierce attack of the Frost Ghosts, the Cyan Steel Main Door's last Never Compromise effect was quickly used up, while the Frost Ghosts also suffered heavy casualties. The Crystal Launcher was simply too effective at killing monsters in such dense environments, easily achieving 10 hits per second!

However, just at that moment, two shouts were heard.

"Everyone make way, make way!"

A short, pointy-eared creature darted out from the monster crowd. He carried a basket of round bombs on his back and held an already lit bomb in his hand.

After his shout, the Frost Ghost Soldiers immediately dodged away in fear.

He aimed and threw, and the crystal bomb landed right in front of Dorm 200.

"Perfect aim!" he shrieked with laughter, revealing two rows of sharp teeth.

Kaboom~

The bomb exploded.

"Damn it!"

Seeing the Cyan Steel Main Door had only twenty durability points left, Xu Lang made his decision without further hesitation.

Actually, the Triple Rashomon Gate looked pretty good too, but Xu Lang knew he had Blood Grudge, so the confusion effect would probably be limited, which was why he didn't choose it.

Some monsters outside saw the door change and couldn't help but freeze for a moment, then attacked even more frantically.

A few seconds later, the Super Alloy Steel Door's durability decreased by one point.

Seeing this, Xu Lang instantly felt relieved and said to Wang Yazhi, "Yazhi, pay attention to repairing the turrets!"

"Okay!" Wang Yazhi responded hastily.

All three turrets along with Ghost Child were under attack!

After seeing the door upgrade, the monsters became extremely frenzied. The bomb monsters no longer cared about their companions' safety, lighting the fuses and throwing bombs every ten seconds.

This couldn't continue - the three turrets' monster-killing efficiency was too low. No matter how they adjusted their positions, they couldn't achieve the effect of clearing out the monsters.

Listening to the ghostly screams outside the building, Xu Lang walked expressionlessly to the Crystal Marble Launcher.

The Super Alloy Steel Door's advantage was its unparalleled hardness, but its disadvantage was the lack of other countermeasures. Continuing like this, the durability would eventually be depleted.

"Let the door handle defense, leave the attack to the turrets... Crystal Marble Launcher, let me see your limits!"

If it were just to deal with these so-called Frost Ghosts, the Flame Marble Launcher might be better, but that would greatly reduce its versatility.

And... Twin Dragon marbles were more expensive.

Expensive means damn good!

The moment the Crystal Marble Launcher was upgraded, Xu Lang didn't check the killing effect but instead opened the information panel.

Copper Coins were rapidly decreasing. If he didn't clear the area in front of the dorm soon, he wouldn't be able to collect money anymore!

Thinking of this, Xu Lang went behind the two crossbows.

Level 3 turrets were actually more than sufficient to handle level 3 monsters, but the problem was he had Blood Grudge - there were just way too many damn monsters!

This is how cheat players are.

Ordinary players only need to calculate whether they have enough money for turrets, whether they'll run at a deficit, and whether it's suitable for the current game round. But cheat players have to consider much more, needing to worry about what kind of turret can maximize output, quickly kill enemies, and quickly collect money.

Not afraid of high costs, only afraid of insufficient firepower!

"With my diligent sweat, with my day and night labor, Silver Iron Wing Crossbow, upgrade for me!"

Diligence was exchanged for strength at this moment!
