"It's too difficult to go from level 4 to level 5."

Absorbing the soul power of a sinking wizard, Tang Fan sighed in his heart.

Level 4 to level 5 requires the soul power of twenty level 4 demons, but obviously, the demons that have appeared so far are all level 2, and even if they are level 2 elite demons, they are equivalent to level 3 ordinary demons.

The soul power of level 3 demons requires sixty, but level 3 demons have not yet appeared, and the number of level 2 elite demons is less than sixty.

And although there are some level 2 demons, however, it is still a little difficult to kill one hundred and eighty, as for the level 1 one, five hundred and forty, even if they are waiting in line to kill themselves, they may not be able to kill them until they are soft, not to mention that the demons will fight back, and they are in groups, and the difficulty is higher.

"It's ...... What are the floors? Wang Qiang asked with a snort.

"Fifteenth floor." Although Tang Fan's breathing was also a little rapid, it was obviously much better, indicating that his endurance was much better than everyone else's.

Starting from the first floor, sprint the stairs layer by layer, constantly going up, and kill a bloody road.

Tang Fan's purpose was to destroy the source of magic power on the top floor, not to kill demons, so every time they entered the first floor, they would rush up the stairs as fast as they could.

But from the beginning of entering the first layer, after killing some of the demons, the smell of blood and movement immediately attracted many demons, and these demons pursued layer by layer, surging like a tide, Tang Fan and they had to tear apart the demons, fighting back and forth.

So far, there have been several elite demons that have appeared, all of them have been killed, and they have been summoned by Tang Fan as level 2 skeleton warriors.

Now, the two skeleton warriors are fighting as the main force in the front, and the two are blocking the back to fight the demons, and it is precisely because of the four level 2 skeleton warriors that they have resisted most of the demons' attacks, and Tang Fan and they have not suffered any losses.

It's just that a few of them were slightly injured.

Even with the strength of the skeleton warriors, in the face of the continuous demonic impact, the bones on the body have been cut out of many scars, but fortunately, the skeleton is not human and does not know pain.

The skeleton warriors continued to kill upwards, and Tang Fan and the others followed closely behind, slowly advancing forward.

From time to time, Tang Fan would release his teeth and attack the Fallen Wizards who were about to release fireballs to ensure the safety of his own teammates.

Fortunately, starting from the stairs on the first floor, the stairs that went up were connected, and the stairs were only about two meters or three meters wide, so that the demons could not form an encirclement in all directions, which invisibly made Tang Fan's attacks a lot weaker.

"I only have three bolts left." Lan Ruolin suddenly spoke.

She had always been protected from the crowd, but the crossbow arrows in her hand occasionally attacked the sunken wizards who were about to release the fireballs, leaving the wizards wounded and unable to chant spells to release the fireballs.

But in most cases, the crossbow arrows shot are difficult to recover, because there are so many demons that no one dares to go deep into the demon group to recover the crossbow arrows, so that even if the number of shots is not much, the crossbow arrows are one less than one.

"We need to rest." Li Sidao, his forehead covered with sweat.

After continuous high-intensity battles, they were all quite tired, and the hunger in the stomach was constantly invading their whole bodies, if they didn't rest, it was estimated that they wouldn't be able to support it for long, Tang Fan also felt that his magic power was not much left, and it would take some time to recover.

"What time is it?" Tang Fan asked.

"It's past five o'clock in the afternoon, and it's almost six o'clock." Wang Meng quickly glanced at his phone.

"It's almost night."

Tang Fan glanced at it, the fifteenth floor was similar to the next few floors, all separated by houses, different sizes and sizes, and in the middle, there was a corridor connecting the entire fifteenth floor.

"Kill over there, let's go inside and rest for a while." Tang Fan pointed to the open door not far away and said.

Under Tang Fan's control, the skeleton warrior opened a bloody path, and Tang Fan and the others hurriedly followed, absorbing the soul power of the slain demon.

After being promoted to level 4, the spiritual power has increased a lot, Tang Fan's soul absorption speed is faster, and the distance has also increased, in the past, he still needed to get close to the demon's head to be able to absorb it, but now as long as he does not exceed a distance of one meter, he can absorb the demon's soul power.

From the stairs to the open door, it was almost a dozen meters, but the demon was heavily blocked, and it was extremely difficult to move forward.

The two skeleton warriors opened the way in front, and the two were responsible for breaking the back, while Tang Fan and the others were constantly wandering around to kill the surrounding demons.

Lan Ruolin only had one of her three crossbow arrows left, and when she rushed through these ten meters, everyone was more or less injured.

Rushing into the room, a hard spike flew in.

Tang Fan reacted quickly, a knife slashed out, just split the hard thorn flying, Li Si was short, like a wind rushed forward, the scimitar in his hand stabbed, Tang Fan stretched out one hand, silently recited the incantation, in less than a second, the teeth flew away, bombarded the elite hard-haired mouse, blasting out a blood hole.

Lan Ruolin quickly raised her crossbow, and the crossbow arrow broke open, avoiding the hard thorns and shooting into the body of the hard-haired mouse.

Under the joint efforts of several people, this elite hard-haired mouse that stayed in the room and did not go out was simply ground to death, and the soul power naturally could not escape Tang Fan's hands.

This room is not big, it looks like a lounge, there is only one door, four skeleton warriors block the door, lined up, kill the approaching demons, the door is closed, the curtains and so on are all tightened.

I turned on the switch, but found that the light was not on, and I don't know if it was broken or the power had been destroyed.

After searching the room and finding two candles and a lighter, Tang Fan and Wang Meng opened their backpacks and took out food and water for everyone.

After eating, it was already six o'clock in the evening, and at this time, the sky outside had become dark, and the whole city was lifeless, and there were no lights, and it was completely dark.

The wind blows, and the desolation is like a ghost, wandering through the streets of the city, making a chilling whining sound, like a senluo hell.

Outside the room, the demons continued to attack, again and again, but all of them were resisted by the four skeleton warriors, and the ribs on the skeleton warriors were also broken several times, and the other bones were more or less scarred, which showed the fierceness of the battle.

The demons are not afraid of death, and they are all level 1 and level 2 demons, and occasionally a level 2 elite will appear, and they can fight a few times with a skeleton warrior, and they will be killed immediately under the joint efforts of the two skeleton warriors.
