"Su Li, you are really getting better and better." Ding Longyun, Gong Xiao, and Xu Haishui could not hide their envy.

Zu Li smiled and said, "What about you, how many spiritual sources are there to break through to level 5?"

He successfully upgraded to level 5, understood the spirit source technique, and unexpectedly obtained a weapon. Su Li was satisfied with this trip and had no choice but to ask for anything else. He decided to help the other four people improve their strength next.

Ding Longyun said: "I'm still missing nine spiritual sources."

"I'm eighteen short." Gong Xiao also reported his current situation.

"I'm twenty-two." Xu Haishui also said.

Then Su Li looked at Xu Xuehui on the side, thinking that she hadn't even reached level 4. Thinking of level 5, it was still far from it. For the time being, she could only let her go first, and strive to help Ding Longyun and the other two break through to level 5 today. In this way, with their current strength, they would not be afraid of the leaders of the Zifeng Building.

"Everyone is not much different, so we will immediately cause the monster to come up." Under the leadership of Zuli, everyone moved the corpse on the roof and threw it down again.

Zuli is now strong and is not afraid of whether he will attract any terrible monsters again. He even looks forward to another rare monster like the dragon rhino.

With the Dragon Rhino Sword that cuts iron like mud, Su Li is confident that he can easily kill it with a rare beast like the Dragon Rhino.

A large number of corpses on the roof were transported and thrown down by everyone, but there was no big noise. Only a few corpse beasts floated up, and the large number of monsters that were originally gathered below seemed to have disappeared.

Finally, Zuli threw the corpse of the dragon rhino, which led to some arrow snake beasts and water monkey beasts.

The number of monsters that finally climbed to the top of the stairs was not more than twenty.

This situation is obviously very abnormal.

"So that's it. It seems that the most powerful monster hidden under the building is the dragon rhino. Once it is killed, other monsters feel that they have lost their shelter and will leave here one after another to find new shelter."

Just like the bottom of the thirty-two-story building they lived in before, the most powerful monster hidden there is undoubtedly the corpse mother. Once the corpse mother dies, other monsters will disperse one after another. Now this situation is happening here.

Looking at the high-level corpse beasts, arrow snake beasts and water monkey beasts gathered over, Zuli counted for a total of fourteen.

"Brother Ding is the least far away now. He only needs nine spiritual sources to upgrade. Let's let Brother Ding break through to level 5 first." Su Li shook his body, then knocked a high-level corpse beast away and threw it out in front of Ding Longyun.

"Okay, I agree." Gong Xiao nodded slightly. She was still eighteen spiritual sources, and even if she killed all fourteen monsters, she could not break through. So she agreed to let Ding Longyun break through first.

Xu Haishui didn't speak, nodded slightly, expressing his agreement. In fact, he didn't have much say among the few people and rarely spoke too much.

"Thank you all," Ding Longyun laughed, raised his right hand, and smashed the head of the high-level corpse beast that fell in front of him, and harvested a spiritual source.

With the help of everyone, Ding Longyun soon killed nine monsters, harvested nine spiritual sources, successfully broke through, and was promoted to a level 5 spiritual source.

Gong Xiao killed three of the remaining five monsters and Xu Haishui killed two of them.

"How about it, what kind of spiritual source skills have you learned?" Su Li looked at Ding Longyun who was breaking through with interest, knowing that once he was promoted to level 5, there would be two spiritual source skills to choose from.

Ding Longyun said excitedly: "It's so interesting. This spiritual source technique can be selected, namely 'Qi Control Technique' and 'Air Missile'."

Gong Xiao said: "Brother Ding, which one have you chosen? What are the abilities of both of them?"

Ding Longyun laughed and said, "Of course I chose the air missile. The name is very awesome. The missile is definitely very powerful. As for the art of controlling qi, it is weird when you hear the name, you can't choose it."

He had already chosen the "air missile" while saying that. As he understood, he showed a look of surprise on his face and said in amazement: "This 'air missile' is actually related to my constant strengthening of my lungs. My lung capacity is very large now. I breathe the air in and combine it with the spiritual source in my body..."

He took a deep breath as he spoke, his chest swelled slightly, then opened his mouth and squirted out the air flow that had just been sucked in with a loud noise.

The air that was sucked in merged with the spiritual source in his body and turned into a white ball of light, spit out from his mouth, flew out in an instant, flew out twenty or thirty meters, and landed on the water.

There was a loud "boom", and a white light flashed on the water surface, and it exploded violently. The water splashed everywhere, with great power.

"Haha--" Ding Longyun looked at the power, surprised and happy, and everyone else showed strange looks. He never expected that Ding Longyun had actually mastered such a powerful spiritual source technique.

"Can you spit out an explosion-proof air bomb in your mouth?" Gong Xiao said in surprise: "There are also such spiritual source techniques."

"It's so interesting." Ding Longyun smiled excitedly and said, "Su Li, do you know? This air bomb is also related to my lung capacity. The greater my lung capacity, the more powerful the air bomb will be. It's not in vain. I have strengthened my lungs these times. I have strengthened my lungs four times now."

The four strengthenings of the lungs have allowed Ding Longyun to extend the breath holding time for fifteen minutes. With the basic four minutes, his total breath holding time has reached an astonishing nineteen minutes.

Su Li smiled and said, "This ability is indeed very powerful, congratulations to Brother Ding." He thought that this ability is suitable for long-range attacks, and it is difficult to use it once close. If he had changed it, he might have chosen the "qi control technique". However, since Ding Longyun chose the "air missile", Su Li would not say anything more.

"There are almost no monsters below, what should I do next?" Gong Xiao looked at Su Li. Now that Su Li and Ding Longyun have successfully reached level 5, how amazing the spiritual source art she has comprehended is. She is indeed envious and wants to upgrade to level 5 earlier. She is very looking forward to what the spiritual source art she can comprehend then.

"Let's change the place, there is still time." Su Li looked at the sky. Although he was not sure of the specific time now, it was estimated that the weather would be two or three hours before dark.

Several people went downstairs and returned to the raft. Ding Longyun pushed the raft behind and said, "Su Li, where are you going now?"

Su Li pointed to another building fifty meters away from here. Originally, because he was afraid that Xu Xuehui would be stimulated, Su Li did not choose to go, but now Gong Xiao and the others were stuck and unable to upgrade. They urgently needed enough monsters. Su Li didn't care much and said, "Go there, you can go directly to the top of the stairs, and I will attract the monsters."
