Despite such a defect, the change of the sunspot still made Su Tang feel a little excited in his heart, because the current level of the sunspot is still very low, but as long as the sunspot has always existed and has not been shattered, then the strength of the bones will continue to increase in the future, and this defect can be weakened or even restrained. Then it is completely foreseeable how powerful the sunspot will evolve in the future! It will definitely become a powerful help for his survival in the last days, and he didn't have time to be happy for a while, taking advantage of the fact that Kuroko's body blocked half of the staircase passage, Su Tang also started his killing...

After a hard battle, Su Tang's physical strength was violently consumed, his body was very tired, his hands holding the weapon were trembling uncontrollably, his breathing rate was no longer stable, and there were some blood scabs on his face and head, this was not his blood, it was the blood that was splashed when he killed zombies.

At first, he still had the heart to dodge, but as the battle continued, he gave up the extra dodge, and the massive consumption of physical strength forced him to try to exchange the lowest physical strength for the maximum result under the protection of Kuroko.

His coat was dyed red and black, dripping with blood, and he looked like a devil. The blood crusts that clotted in parts of the clothes seemed to be a testament to the intensity of the battle. Kuroko has been strengthened by bones because of upgrades, and his ability to continue fighting is stronger more than a little, so under the battle, the bone strength is still about 55%, but because Su Tang's attack speed has decreased, the mortality rate of zombies is not as good as the beginning, and the bone strength of Kuroko has gradually failed to keep up with the consumption rate, and gradually fell below 50%, and the skill: fearless, when Su Tang felt bad and secretly complained.

Li Bin and the others finally moved, "Susu, come up quickly", Nangong Ya stood at the top of the stairs and shouted with a flushed face.

Su Tang glanced back at her, only to see that her pretty face was covered with beads of sweat, her face was full of anxiety, as if she was worried about something, Su Tang's heart was inexplicably warm, and after her, Su Tang's frozen heart trembled for the first time.

"Got it, you go back quickly, I'll come right away", Su Tang saw that she had the intention of coming down and hurriedly stopped. He raised one hand, silently reciting the "Fireball Technique" in his heart, and as the 5 points of spiritual power were extracted, a scorching fireball quickly condensed in the air. Su Tang pushed out the fireball with one hand, and shouted at the sunspot who was still fighting in front of him: "Kuroko, lie down", and the sunspot who was fighting with the zombies heard the master's order, his body shook, and he got rid of the entanglement of several zombies and prostrate himself on the ground, dodging the fireballs that flew in, and the zombies did not have such an operation.

They were only instinctive, and as the fireball flew out, they were squeezed together by the continuous repulsion and collision, only to hear, "boom", the fireball technique exploded, and the wonderful scene of the last fireball spell was staged again. A piece of zombies in front of them were directly shattered by the explosion, emptying the staircase 3 meters in front of them...

"Kuroko, bump into it", Su Tang didn't care about how many zombies he killed, and let Kuroko rush towards the zombies 3 meters away, while he rushed forward to pick up the items that the zombies exploded. Holding the items he picked up, Su Tangtou would not leave and shouted, "Kuroko, follow me." Because the strength of the sunspot is already below 50%, he has a +5 bonus to all his attributes when he turns on the fearless state, and it is easy to kill the zombies entangled with him, and quickly withdraw from the battle and chase after Su Tang.

Rushing up the steps, looking at the piles of various things that were regarded as obstacles on both sides of the corridor, Su Tang breathed a sigh of relief in his heart, and quickly interspersed along the gap left behind, and Su Tang, who rushed through the end of the obstacle, collapsed on the ground and breathed rapidly.

"Heizi, seal the intersection", Su Tang, who was sitting on the ground, said weakly.

Kuroko, who accepted the order, stepped forward and smashed several iron cabinets between the cracks, and smashed them hard.
