Chapter 523: Release your vitality

Zhang Su's gaze stayed on Chen Hanzhou's back, watching him return to behind the car and sit among the crowd. He could already be sure that he had a problem, but for now, at least he hadn't posed a threat to the people around him. Everything could only be studied after solving the trouble in front of him.

"Bozai, some zombies came over there. You and Old Liu take a few more brothers to wait at the intersection."

Glancing up, Zhang Su found that a few ordinary zombies were slowly approaching from the distance, still a thousand meters away. They hadn't discovered anyone here yet, but just in case, he had to arrange for people to guard against it.

"I... sigh, fine."

Lu Yubo was very reluctant. Knowing that a big battle was imminent, he wanted to watch the battle, but he knew he couldn't disobey orders. Fortunately, Liu Yao was also uncomfortable, so he pointed to a few combatants who didn't look pleasing to the eye and walked toward the intersection, looking at the battle circle with lingering attachment.

*Awoo, woo, awoo... *

The black gas zombie had no consciousness. After repelling one strong enemy, it welcomed another formidable enemy, but this formidable enemy didn't intend to fight it.

After Tachibana Mai-Sakura cooperated with Zhang Su to rescue Chen Hanzhou, she strolled around, taking the black gas zombie to circle, looking like she was teasing the zombie, but her expression was very serious, observing carefully from time to time, and even sniffing her nose, as if smelling something.

"The attack distance of the black mist is about 2.6 meters. Beyond this distance, it won't manipulate the black mist to attack, but will only mechanically chase."

Knowing that Zhang Su had walked behind her, Tachibana Mai-Sakura shared the conclusion she observed.

"What exactly is this ability? And what is the connection with the restaurant?"

Zhang Su looked at the black gas zombie with a puzzled face. A shield similar to a domain that could be retracted and released, could be materialized for offense and defense, and could also create pressure inside to squeeze objects that entered it—too damn high-tech! He couldn't figure out what was in the restaurant that could make it mutate into such an awesome ability!

Previous mutated zombie abilities were all related to the environment they were in. Zombies in the quarry mutated petrified skin, zombies in the agrochemical plant were buried in chemical raw materials and affected to become zombies that could spit venom, and zombies trapped by metal machine tools had parts of their bodies turned into superconducting metal...

What could be in a restaurant that could evolve into black mist, and most importantly, could be retracted and released at will? Pufferfish? "Sniff it, is it the smell of liquefied petroleum gas?"

While continuing to dodge the black gas zombie's chase, Tachibana Mai-Sakura said, sniffing her nose, and a faint smell entered her nostrils.

Liquefied petroleum gas itself is colorless and odorless, but it would be very dangerous to maintain this characteristic in the civil field, so a chemical substance like ethyl mercaptan was specifically added. The smell is unique and strong, allowing people to quickly detect it when there is a trace leak, and this smell is hard to cover up! "Ah? Is there?"

Zhang Su was full of surprise. His hearing and vision had been strengthened, but his sense of smell hadn't changed at all. Plus, it was freezing cold and his nose was a bit blocked, so he wasn't very sensitive to the smell of liquefied petroleum gas, let alone the thick smell of smoke.

"Fine, even if liquefied petroleum gas caused it to mutate, what does liquefied petroleum gas have to do with this black gas shield? That thing is transparent!"

"I don't understand. You can ask the chemistry teacher after going back."

The education Tachibana Mai-Sakura received since childhood wasn't in that aspect of science, engineering, and agriculture, so she didn't understand liquefied petroleum gas...

"It's fortunate that we didn't use fire to burn it just now, otherwise it might really have caused an unimaginable disaster."

Zhang Su stared at the swaying zombie, feeling a lingering fear in his heart. The black gas shield didn't have any special reaction under bullets and explosions, but it was hard to guarantee that it would still be intact under thousands of degrees of high temperature. If its flesh body was equivalent to a storage tank for liquefied petroleum gas, then the whole thing would explode, and the power would probably not be less than the venom zombie!

"Kill it and study it slowly. Do you want to do it yourself, or should I?"

Tachibana Mai-Sakura didn't have the habit of teasing prey; she was just observing before.

"I'll do it!"

Zhang Su saw Chen Hanzhou's difficult battle just now and felt itchy to challenge this new enemy.

"That's right, you are full of vitality, release it!"

Tachibana Mai-Sakura left a thought-provoking and *chuunibyou* sentence, turned around, and ran toward the Le Gou mall, leaving Zhang Su in a mess. In his mind, the figure of the Blue Beast couldn't help but surface. *Awoo, awoo! * After a trance, Zhang Su focused his attention on the black gas zombie again.

"I really want to keep you and study you well, but unfortunately I don't know how to control your ability, so I have to kill you."

Zhang Su thought in his heart, took down the rifle and carried it in his left hand, and in his right hand was the sharp machete. He didn't intend to get entangled in battle and prepared to send the black gas zombie on its way directly. If possible...

The battle was on the verge of breaking out. The combatants on the first floor of the Le Gou mall held their breath and watched the battle. Some people even climbed onto cars to get a better view, and some even crossed the green belt and stood on the side of the road, showing that they trusted Zhang Su very much.

The windows on the second and third floors were crowded with pairs of eyes, reflecting the light of hope in the darkness.

"Hurry, hurry, dodge, let me see my big brother!"

Zhao Dezhu finally couldn't help but run out of the clothing store, pushed the crowd away, and stood by the window, just in time for the moment the battle broke out.

Violent attack, moving like a rabbit, feint!

Zhang Su wasn't pedantic or stubborn. He naturally wouldn't abandon the flaw that his companion had tested with his life.

A seemingly violent attack was actually a move he had already thought of. He held the machete and slashed toward the black gas shield. He heard a *puff* sound, and a shallow mark appeared on the sturdy shield, about two centimeters deep.

In a defensive posture, even Zhang Su's almost full-force blow couldn't cause substantial damage to it, but even so, it made the spectators nod involuntarily. Before, only bullets could break the black gas shield; this was the first time using a melee weapon to break the defense.

*Awoo... *

The black gas shield was damaged, and the zombie seemed to have suffered some kind of provocation. It opened its mouth and roared at Zhang Su, and then, without any accident, the black gas shield expanded violently!

"Hmm?"

Zhang Su was shrouded in white mist, always grasping every move of the other party. At the first moment the flocculent matter was active, he knew this was the pre-attack move and immediately retreated, but he felt something was wrong after the black gas shield bulged!

Tachibana Mai-Sakura had just told him that the shield's attack distance was about 2.6 meters, but he had already retreated to nearly 3 meters, and the black gas shield was attacking him rapidly. The naked eye couldn't perceive it, but in the white mist, he could clearly perceive that the flocculent matter was frantically moving and didn't show signs of stopping.

*Slap. *

At the critical moment, Zhang Su exerted force on his ankles, his soles slapped the ground, and after his leg strength was exhausted, he still let himself leap more than a meter back, finally dodging the black gas shield's attack. Visually, it was more than three meters from the edge to the zombie! A big ball with a diameter of more than six meters appeared on the dim street, and the black mist didn't become sparse because of the expansion, which was very conspicuous.

"It's broken!"

Tachibana Mai-Sakura, who was watching the battle on the side, felt ashamed in her heart and hurriedly said: "The information I told you is inaccurate, don't believe it!"

Zhang Su curled his lips. He had already guessed the reason.

The black gas zombie's previous attacks hadn't used its ability to the limit. His attack just now caused damage to the black gas shield, so it also received a more violent retaliation. Before, when he used bullets to shoot and detonators to explode, the zombie didn't react because the attack distance was far from enough.

Although these zombies seemed to have no consciousness, their combat instincts were very logical, at least they wouldn't do what they considered useless work.

*Whoosh... *

The expanded black gas shield retracted rapidly. Because it expanded larger, the retraction process took a little more time than before. This zero-point-something second of time made Zhang Su's eyes light up.
