Killed with one blow, the corpse beast's head shattered and flesh splattered.

A spiritual source appeared and shot on Zuli's forehead.

A new message appeared in my mind.

"Level 1 Spiritual Source: Spiritual Source 9/10"

Su Li was so excited that she was only the last spiritual source.

A low shout came from his mouth, and Zuli rushed forward.

These corpses seemed to have been awakened, abandoned the corpse of the one-eyed frog that had been eaten, and surrounded Zuli.

In addition to the one he had just smashed his head, there were five left in front of him.

Su Li calculated silently in her heart, feeling a little regretful that there were too few corpse beasts in front of her. He liked such low-level corpse beasts that were not strong but could provide spiritual sources for him. The more the better.

As soon as the figure flashed, Su Li's eyes captured the attack trajectory of these low-level corpse beasts, easily dodged, and then the hammer in his hand hit again.

With a "boh", another corpse beast fell down, and a spiritual source appeared in its body and flew towards Su Li.

"Level 1 Spiritual Source: Spiritual Source 10/10"

"It's done." Zuli was a little excited.

As the spiritual source in the body reached 10/10, a strong heat surge immediately surging the whole body, followed by an extremely powerful force burst out.

In this moment, his strength, speed, reaction, five sense sensing, and comprehensive physical energy were greatly improved and strengthened, and he even became excited deep in his heart.

This is an indescribable excitement.

In my mind, messages came one after another.

"Start promotion, successful promotion"

"Level 2 Spiritual Source: Spiritual Source 0/20"

"Basic Strengthening: Strengthening Lung Type I"

"Special Skill: Peeping Runes (Incomplete)"

"Strengthening choices, improving lung type I, strengthening stomach, strengthening muscles, only one of them can be selected"

Feeling the surge in his body's power, Su Li felt that as he became a level 2 spiritual source, his power had increased by at least nearly 100 kilograms. If he had previously been able to burst out five hundred kilograms of power, he could now burst out at least no less than six hundred kilograms of power.

The remaining four corpse beasts that could move rushed up. Su Li didn't have time to choose what to strengthen, so he swung the hammer in his hand. Although the hammer was not long, it was an iron product and had a certain weight. Although the weight of this hammer was too light for Su Li's current strength, it could still explode with terrible lethality. As long as it was hit by his hammer, the bones would immediately break, and even the hardest skull was no exception.

After a meeting, Su Li smashed the head of a corpse beast again. Seeing the corpse beast fall down, the spiritual source appears and is fused into the body by himself, but there is almost no change in the body.

As he became stronger and stronger, the changes caused by this spiritual source after he absorbed it became smaller and smaller. Now, it can be almost ignored.

What surprised him the most was that he absorbed the spiritual source this time, but no new message prompt appeared in his mind.

"What's going on?" Su Li was slightly stunned. Then he killed all the remaining three corpse beasts. Although they all absorbed the spiritual source, there was no change.

He still lacks 20 spiritual sources that he needs to evolve again.

"Is it because I became a level 2 spiritual source, but these corpse beasts are too low-level, so it is useless to absorb their spiritual sources?"

Su Li pondered slightly and thought of this possibility.

If this is true, it means it will be difficult for him to become stronger and he needs to hunt stronger monsters.

"A person who has been promoted to a level 2 spiritual source has gained another opportunity to strengthen. Now there are three options. One is to continue to strengthen lung type I, the second is to strengthen the stomach, and the third is to strengthen the muscles. Which part should I choose to strengthen."

"The function of strengthening lung type I is to enhance lung capacity and can extend the breath holding time for two minutes. If you choose to strengthen this, it should make the breath holding time longer."

"I just don't know what kind of abilities you can gain by strengthening your stomach and muscles."

Zu Li knew that for a city that was flooded, the length of time to hold his breath can be said to be extremely important, but his physical strength is now strengthened and his breathing time will not be less than two minutes. In addition, the two minutes of strengthening lung type I enhancement means that he can hold his breathing for four minutes now.

"Four minutes should be enough for the time being. Even if it really falls into the water, it will be enough to float out of the water for breathing. If it cannot float for so long, it will probably be a terrifying thing. Even if you can hold your breath for one or two more minutes, it will be a bad luck."

After thinking for a long time, Zuli also chose to strengthen his muscles out of curiosity about strengthening the other two body parts.

According to his own guess, strengthening muscles should be related to strength. Fighting with the one-eyed frog made him understand that strength is the most important. Only when the strength is strong enough can you hunt more powerful enemies.

As he chose to strengthen his muscles, a new message soon appeared in his mind. At the same moment, he felt that his muscles all over his body began to change unusually.

"Basic strengthening obtains: muscle-building type I"

"Muscles are basically strengthened, and their strength is enhanced, their ability to control muscles is enhanced, and their muscle toughness is enhanced."

Su Li took a deep breath and felt that all the muscles in his body were active, like little snakes twisting and vibrating. He could see his chest, abdominal muscles, arms, thighs, calves, and muscles everywhere in his body were expanding, bulging and thrusting, and a stream of force burst out from these muscles. Not only that, his control over these muscles is enhanced, and his thoughts can strengthen these muscles, make the muscles harder, and enhance his ability to resist strikes.

"It's incredible that the muscles in my body have been strengthened. My current strength is probably increased by another 100 kilograms. Not only has it been strengthened, but I also seem to be able to artificially control these muscles. I can make any muscle expand and become hard. In this state, I can resist some attacks."

Su Li tried to control these muscles, and was surprised and happy. He broke through to become a level 2 spiritual source. His strength increased by about 100 kilograms, and his strength reached 600 kilograms. Now, as he realized "Muscle-Growing Type I", he gained about 100 kilograms of strength. It can be said that the power that could burst between his arms was no less than 700 kilograms.

Seven hundred kilograms, three hundred and fifty kilograms, for an ordinary office worker like Zuli who didn't exercise much, this is an unimaginable powerful force.

This means that Zuli can lift five humans with an average weight of 70 kilograms now.

"This spiritual source is really incredible. It can actually make people so powerful, and I can become even stronger. Unfortunately, I need twenty spiritual sources, and the spiritual sources obtained by killing such low-level corpse beasts are no longer effective."
