"Ding, City No. 5354 did not eliminate all the monsters in the fourth wave within the specified time. The remaining monsters will follow the fifth wave and continue to attack."
When this reminder came from the domain network again, the three Xu Tianyu immediately came to the front of the cave, which was already full of corpses.
"With hands, maybe the corpse can help us burn some enemies."
Both the White Demon and Hu Tiannan nodded, and at the same time the two black fireballs in their hands were thrown into the pile of corpses.
Xu Tianyu also threw a few fireballs. Although he was not as domineering as the magic flame, he could still ignite the corpses on the ground.
"Boom~~"
With the familiar crash sound, Xu Tianyu knew that the fifth wave of slimes was coming.
"return to."
The three Xu Tianyu quickly retreated, while the Void Beast stood up outside the fire, waiting for the enemy to charge.
"Wow~"
The slime seemed to only know the charge, completely ignoring the fire in front of him, plunged straight into it, and was quickly killed.
But this is not the end, but just the beginning.
More and more slimes rushed over, using their bodies to actually smash a path.
"Damn, it's fierce, we continue to throw fireballs."
Seeing this scene, Xu Tianyu quit, poked a fireball and threw it on the body.
With the support of Xu Tianyu and the others, the flames grew bigger and bigger. Although there were still many slimes crossing the sea of fire, they were eventually killed by the void beasts waiting outside.
"Ding, congratulations to the master for hunting a slime and gaining 10 experience points."
"Ding, congratulations to the master for hunting a slime and gaining 10 experience points."
...
"Ding, congratulations, Master, the experience of Sky City has met the conditions for upgrading, whether to start upgrading now."
The sudden system prompt made Xu Tianyu start to move.
"Hey, can you upgrade again so soon?"
"Ding, it is detected that there is only one building in Tianyu City, and the upgrade conditions are not met. The upgrade failed."
Xu Tianyu hadn't been happy for a minute, the system prompt came again.
Xu Tianyu only remembered that in order to upgrade Tianyu City, in addition to the need to increase the experience value to 10,000 points, it also needs to build a farm house, a barracks, a wall, and three buildings.
It's a pity, now he's fighting, and he doesn't have the time to build.
"Ding, because the experience value is full, the power storage function is passively turned on, and the excess experience value will be stored, and when the owner needs it, it can be directly used to upgrade."
Xu Tianyu's intimate reminder again made Xu Tianyu happy.
I thought that so much experience of slimes would be wasted, but I didn't expect that there would be unexpected surprises.
The battle is still going on, but with Mazaha's void beast, the slime can't get through any storms at all.
"Ding, City No. 5354 did not eliminate all the monsters in the fifth wave within the specified time. The remaining monsters will follow the sixth wave and continue to attack."
...
"Ding, City No. 5354 did not wipe out all the monsters in the ninth wave within the specified time. The remaining monsters will follow the tenth wave and continue to attack."
Unconsciously, the test has reached the final level, but apart from the first level, Xu Tianyu and others have failed to pass.
Although depressed, they didn't have time to explore, they could only get rid of the densely packed slimes in front of them.
