"Brother Jiang, Brother Jiang…"

Jiang Liushi faintly heard someone calling for him in his sleep, and he tried his best to open his eyes . When he did, Zhang Hai and the others could be seen around him, staring at him nervously . He was lying in his bed inside the minibus, and the light was quite smooth on the eyes .

"Why am I here? Did I faint?" Jiang Liushi asked . He couldn't remember what had happened to him except the dizziness he had felt earlier .

"Brother Jiang, it was Ying who insisted on carrying you back to the minibus," Zhang Hai explained .

Originally, Zhang Hai intended to carry Jiang Liushi back to his room, but Ying insisted on carrying him back to his minibus . Zhang Hai gave everything in detail as he had found the whole situation strange . Although Ying looked like a young girl, she was quite strong, and Zhang Hai could only give up on his initial judgment and follow them back to the minibus .

'Ying?' Listening to Zhang Hai's words, Jiang Liushi started to search for Ying . He looked at the petite figure dressed in black that had a cold countenance, but her eyes were locked on him the whole time .

'The evolutionary crystal you consumed was too pure, and its excessive energy caused some damage to your body, and thus, affecting your nervous system . After all, you are an ordinary human who has not evolved the same way as others . In other words, your cells could only bear a limited portion of pure energy,' Ying explained to Jiang Liushi through their mental connection .

As a matter of fact, Ying's main mission was to protect and act the moment Jiang Liushi's life was in danger . 'I carried you back to the minibus because it's the only place in which you can recover…'

'I . . . How long will it take me to recover?' Undoubtedly, this was the question Jiang Liushi was mostly concerned for . Jiang Liushi's physical discomfort led him to feel dizzy, which was bad if he was in the middle of a battle . Moreover, he had to take part in the level-5 mission and had to be in perfect condition .

'You need at least a month to recover naturally . At the same time, you can't consume more than a third of an evolutionary crystal,' Ying answered .

Jiang Liushi smiled wryly at this answer . He didn't expect that the pure evolutionary crystal would not be good for him . However, he came to an understanding . It was similar to eating . If one person ate too much food, they would feel uncomfortable .

'Do you know of any methods that can let me recover faster?' Jiang Liushi asked .

'Let me check… . ' Ying answered and then Jiang Liushi felt that was Ying scanning his mind .

'In combination with the host's physical condition, the host can choose the option of level-2 genetic fluid and strengthen the body again,' Starseed's cold voice sounded in his mind .

However, Jiang Liushi was as worried as before because there were no level-2 genetic fluids in the lab at all .

'Do I need to upgrade the lab first?' Jiang Liushi asked .

'Yes, one level-2 mutant nucleus is needed to upgrade the lab,' Starseed confirmed .

'Okay, upgrade it now!' Jiang Liushi was very decisive . According to Starseed's description, the level-2 genetic fluids could not only heal the damage he had received but also increase his strength .

"How are you feeling, Brother Jiang? If only Yuxin were here, it would be much better," Ran Xiyu looked at Jiang Liushi and asked nervously .

Ran Xiyu had noticed that Jiang Liushi and Ying had been communicating with each other mentally, so she felt a little worried . Although she was a psychic paranormal, due to Starseed's existence, she could never sense Jiang Liushi's mental state . She could only sense his emotions .

"Don't worry . I'm okay . I will visit Yuxin's home tomorrow . I think I will be okay by tomorrow," Jiang Liushi comforted Ran Xiyu .

"Uh . " Ran Xiyu nodded .

Jiang Liushi stood up and walked to the minibus cab, from which strange sounds came, and then metal plates appeared, sealing the room . Usually, Jiang Liushi would protect his secrets tightly . Although he trusted his team, he didn't want to explain everything as his condition was complicated .

Zhang Hai and Sun Kun looked at each other and then stared at the sealed room with glowing eyes . In their eyes, Jiang Liushi was a mystery .

As soon as Jiang Liushi entered the cab, he placed a level-2 mutant nucleus in the meatal groove skillfully .

'…second upgrade of Biological Laboratory has been selected . Initiating construction!'

Half an hour later, Starseed notified Jiang Liushi, 'Successful upgrade!'

A holographic scene appeared in Jiang Liushi's mind . Unlike the previous messages, there was not only information but also images .

'The level-2 genetic fluids which the laboratory can create are…'

Jiang Liushi read through the descriptions quickly . He found the same common genetic fluids as before, but they could further enhance defense, strength, agility, and brain regions . At the same time, Jiang Liushi could see vivid virtual images of his body in his mind now . He was in the best of spirits . As for the elemental types, which were also similar to the previous introductions, there were some new abilities now . However, the consumption of mutant nuclei was terrible! Jiang Liushi could find only a few low-cost performance elemental types .

After reading and thinking carefully, Jiang Liushi decided to choose one kind— Level-2 blood evolution gene fluid!

Jiang Liushi had already consumed the level-1 blood evolution gene fluid, through which he had gained greater resilience and strength . Blood evolution meant that people could obtain a stronger blood circulation system, which could mutate the blood cells, giving them a greater ability to carry oxygen, nutrients, and energy . Although the production of the level-2 gene fluid needed to consume five level-1 mutant nuclei, Jiang Liushi didn't hesitate at all . As long as the level-2 gene fluid could be produced, the third or even the fourth generation would also be possible . For Jiang Liushi, this would be the happiest occasion . Without any hesitation, Jiang Liushi placed five level-1 mutant nuclei into that metal groove!

A deep, painful roar came suddenly from the sealed cab . Zhang Hai was scared by that sound, and then they all looked at Ran Xiyu .

Ran Xiyu used her mental power to sense Jiang Liushi's state, and she found that Jiang Liushi was in great pain . She rubbed her brow to ease the feeling of dizziness she got by sensing Jiang Liushi's feelings and kept observing him .

"Brother Jiang is fine," Seeing Zhang Hai's worried looked, Ran Xiyu said . She didn't know what had happened to Jiang Liushi, but she found that he had become stronger .

'Om-'

As the metal plates of the sealed cab retreated, Jiang Liushi appeared in front of everyone . There were traces of sweat on his face . It was obvious that he had been tormented by terrible pain in that sealed cab . A lot of sweat was evaporating due to his body temperature, leaving only slight traces on his clothes . In addition to sweat, his skin had become as delicate as jade . Although Jiang Liushi was just an ordinary person, his temperament was even better than a paranormal .

"Brother Jiang, I feel you are a little different," Zhang Hai said .

"Don't worry . I'm fine, pretty good . " Jiang Liushi smiled faintly .
