"I'll take the sunspot to guard here, Li Bin, you take Nangong Ya to the back room to find something that can block the stairs, like we did last time, go quickly", Su Tang, who was standing at the staircase on the third floor, said to Li Bin hurriedly.

Li Bin nodded to show that he understood, although Nangong Ya didn't know what they meant by what they said last time, she also understood that she had to follow Li Bin.

After explaining the tasks of the two, Su Tang asked Kuroko to rush towards the tide of corpses, preparing to drag the zombies on the stairs.

Kuroko rushed into the corpse tide and picked up the novice wooden stick and swept across the area, and the strong force burst the zombies that rushed to the front.

Looking at the performance of the sunspot's bravery, Su Tang's heart settled down a little. Sure enough, it was right to choose to upgrade the Undead Warrior skill!

Remember when Su Tang gained a little skill point? Su Tang used it to strengthen the skill of summoning undead warriors.

At this time, Kuroko is already an undead warrior who has been strengthened by skills.

"Beginner Level 3 Otherworldly Summoning Body Undead Warrior (Enhancement +1): Strength 18 Agility 18 Spirit 14 Strength 266/280 Skills: 1. Fearless [When the strength of the Undead Warrior is less than half, gain all attributes +5 status and continue until the strength recovery is higher than half or the death ends, the Undead Warrior has no pain and is only loyal to the summoner] 2. Bone Enhancement [Every time the Undead Warrior kills an enemy, the Undead Warrior will extract the opponent's bone essence to restore his own bone strength and increase the upper limit of strength] Every time you upgrade the undead warrior all attributes +1 strength extra +1 "The strengthened sunspots, not only the strength of all attributes +1 has increased significantly, but also the skills of bone strengthening, and in the future upgrades, the strength will be additional +1.

(1 point of strength attribute = 20 points of strength value), looking at the gorgeous attribute of the sunspot, I once again felt the bitter taste of the master being inferior to the servant.

The battle continues, and the sunspot who killed the zombies in the front row is standing in place waiting for the zombies to come, swing the stick, kill, swing the stick, kill!

Killed several zombies in a row, but the good times didn't last long, a large number of zombies arrived, Kuroko was surrounded by a group of zombies and bitten, patting, unable to reach out and wave the weapon, with the attack of the zombies, cracks appeared on Kuroko's bones, and the strength value continued to decline, dropping by 7% in just a few seconds.

Su Tang knew that it was time for him to make a move! So Su Tang, who was holding a pseudo-Tang knife, rushed to Kuroko, and from the side of Kuroko, he swung his knife and cut off several zombies that pounced on Kuroko.

Kuroko, who had just escaped from the trap, was surrounded by the corpses that surged up again before he could raise his wooden stick to attack.

Su Tang was about to step forward to help, but saw that Kuroko's body suddenly shook, and the bones split into multiple bone spurs and pierced into the corpse of the zombie.

And Kuroko's body actually emitted a dark light at this moment, Su Tang noticed that the strength value of Kuroko was constantly recovering, and the upper limit of strength was increased by 30 points.

This is... Bone strengthening? This sudden change stunned Su Tang, and in Su Tang's subconscious, he thought that the skill of bone strengthening should be consistent with the state of using the active apple, and it would work in a non-combat state.

I didn't expect that Kuroko could be used while still in battle?? Recover while fighting.,This skill is quite perverted.。

It directly strengthens Kuroko's continuous combat ability, because Kuroko has no physical attribute, as long as the strength can support its actions, it can fight.

And the skill of bone strengthening provides him with the ability to continue fighting, and bone strengthening will also increase the upper limit of the strength value, giving Kuroko permanent strengthening!

But in the subsequent battle, Su Tang discovered that this seemingly powerful and perverted skill had huge flaws.

The bone spurs that the sunspots are separated will be interrupted in battle, and breaking them means that they will not be able to absorb the bone essence of the zombies.

Moreover, the sunspot divides the bone spurs and also consumes the strength value, because the bone spurs are not created out of thin air, but the bones grow out of it, and the strength value of its bones is apportioned, and the strength value is naturally reduced.
