After two or three hours of flight, the transport plane slowly descended.

  Tian Shao and others walked down from the plane.

  At this moment, the place where they are located is the central area, the most prosperous section of the chaotic area, and the major forces inside are basically established here, including the Shengdian Group that stirred up trouble.

  The central area is divided into four major districts.

  The target of the joint squad this time is the biochemical research institute located on the edge of S city.

  Arrived at the exact location.

  Tian Xia began observing her surroundings.

  As this is on the outskirts of the city, there isn't much foot traffic or many buildings.

  But here is coincidentally the industrial zone of S city, large and small factories are distributed nearby, these chemical plants, garment factories, machinery factories and other buildings provide almost perfect cover for the biochemical research institute.

  A great talent often lies hidden in the crowd.

  If it weren't for the intel from the Savior, probably no one would have thought that in this steel forest, a huge research institute was hidden, and even more terrifying experiments were being carried out.

  Shengdian Group's means are really high-handed.

  There is no wall in the world that does not let wind pass through.

  Today, Tian Yan and his men came here fully armed with the purpose of destroying this biochemical research institute!

  Avoid hiding surveillance in the dark.

  The combined team maintained a tactical formation as they approached the main gate of the biochemical research institute.

  The main gate of the institute was guarded by a group of mercenaries.

  In order not to alarm the snake by hitting the grass, and to avoid triggering an alert that would make the people inside the institute aware of it, this group of mercenaries must be quietly eliminated.

  Heavenly Retribution and Fallen Angel as vanguard naturally took the lead in this situation.

  Two people rushed forward.

  Taking advantage of his agility and stealth, he slowly crept up behind the patrolling mercenary.

  Then, Tianxia and the fallen angel made their moves at the same time.

  Whirlwind Kick skill activated.

  Under the blessing of the purple golden light, Tianxia's right leg swung down like a mallet and heavily smashed into the chest of a mercenary.

  The skeleton suddenly burst with a loud crackle.

  This mercenary is merely at the level of a second-rate mercenary.

  Endured a high-level kick from the elite Tianxia, his chest immediately caved in, and blood flowed from all seven orifices as he let out his last breath.

  But his body had yet to fall when Tian Shu struck again.

  Mind-linked spatial backpack.

  Nepal - Crystal Soul was taken out by Tianxia.

  Quickly advancing forward, Tianxia's arm swung in a continuous motion, and the remaining two mercenaries were directly beheaded by Nepal - Crystal Soul.

  "Ding, host killed 3 level 2 ordinary mercenaries, obtained 60 kilograms of Kylin."

  The system prompt tone sounds.

  After awakening as an Esper, killing targets with a lower level than oneself results in reduced Kyrium gain. One must kill enemies of the same or higher level to receive substantial rewards.

  Three mercenaries have been killed.

  Tianxia turned his head to look at the fallen angel's side and found that she had also ended her battle, with several corpses lying horizontally under her feet.

  The guardian has been resolved.

  The other members of the joint team came forward one after another.

  Next is to infiltrate into the interior of the biochemical research institute.

  Koutei inserted the cracked U disk, but there was no response.

  It seems that compared to the underground research institute that was destroyed before, Sheng Dian Group has set up a higher level of defense for the biochemical research institute in S City.

  Since ordinary methods cannot be used, then we can only take an unconventional approach.

  The captain of this joint team, Zhao Yi, decided to directly use plastic explosives to blow open the gate.

  Then, Ling and Zero began installing bombs.

  Tianxia and others were on guard at the side, preventing the enemy from discovering or launching a surprise attack.

  The plastic bomb was quickly set up.

  As the spirit fox pressed the detonator button, a burst of flames erupted instantly.

  The massive force not only blew open the gates but also destroyed the first floor hall of the biochemical research institute.

  "The obstacle has been cleared, rapid advance!"

  Zhao Yi gave orders.

  As a vanguard, Tianxia naturally took the lead and charged into the biochemical research institute with his M4A1-SS at the ready.

  The explosion clearly heralded the arrival of the raid.

  At this moment, the alarm inside the institute is ringing non-stop.

  Some low-ranking researchers even started running around, trying to hide and avoid being discovered by Tianxia and others.

  The stationed mercenaries have arrived.

  They did not pay attention to the chaotic scene inside the institute, but immediately exchanged fire with Tianxia and others.

  These mercenaries have quite intense firepower.

  But for top-notch mercenaries like Tianxia and his peers, it's somewhat beneath them.

  Hiding behind the pillar in the lobby on the first floor.

  He judged the distribution of firepower on the opposite side based on the sound made by bullets hitting the standing column.

  Due to the limited number of bullets in the magazine, these mercenaries cannot fire for a long time.

  And when they stopped to reload, it was the moment for a counterattack.

  Sure, here is the translation:

  As expected, after scanning for a few seconds, Tianxia sensed that the frequency of bullets hitting the pillars had dropped to its lowest point.

  It's now.

  The heavenly evil emerges from behind the column and flies out sideways.

  But in the process of moving, mobilize every muscle all over the body, keeping the body always in a balanced state.

  Raise M4A1-SS.

  In the field of view, the reticle turns bright red as it locks onto a target.

  Pull the trigger.

  One by one, the bullets were pressed into the barrel and then pushed out of the muzzle with great force produced by the burning gunpowder, hitting several mercenaries who were reloading with high accuracy.

  "Ding, host killed 3rd-level ordinary mercenary x4, obtained 120 kilograms of Kylin."

  The alarm sounded, but Tian Shao ignored it.

  He held an M4A1-S at the other end, continuing to fire in short bursts at the other mercenaries inside the lobby on the first floor.

  Other team members are also like this.

  All holding purple-quality firearms, shooting and killing like a hot knife through butter.

  Especially Coutinho.

  He held an MG3 - Silver Killer with his left hand, and his right index finger tightly gripped the trigger.

  The bullet in the cartridge is quickly brought into the chamber by the transfer of the bolt, and then ignited by the impact of the primer, producing high-temperature and high-pressure gas instantly, which propels the projectile out.

  The suppressive power of machine guns is naturally not trivial.

  Not to mention the machine gun in Kote's hand is the MG3-Silver Killer developed by the Lurker Alliance, which can cause more damage to biochemical mutants.

  Although the bullets locked onto the target were not mutants, the powerful force still made people dare not to approach. Every time the muzzle swept across, the whizzing bullets would knock down a large group of mercenaries on the ground.

  The joint squad's offensive was quite fierce.

  More and more guardians were killed by Tianxia and others, and the resistance force on the first floor of the hall was getting smaller and smaller.

  But then something changed.

  The mercenaries who were originally shot and killed have all shown symptoms of mutation.

  Deeply sunken eye sockets, murky pupils bursting with a fiery green glow.

  The lifeless corpse began to convulse violently.

  Skin and flesh withered quickly, turning gray and stiff, yet under the drive of biochemical viruses, they supported the rotting corpse, transforming into a zombie that only knew how to slaughter.

  The Heavenly Venerable who was firing noticed the appearance of zombies first.

  He immediately opened fire and reminded:

  "It's a zombie outbreak, everyone open fire!"
