The fighting experience has brought a lot of pressure to the members of the alliance. They displayed extraordinary combat skills and unparalleled strength, making it difficult for the members of the alliance like never before.

Bella's squad encounters members of the Special Forces in the dark forces' stronghold. These enemies are agile and full of killing in every move. Bella and his teammates faced a formidable opponent, but they didn't back down. Instead, they work more closely together, support each other, and work together to deal with enemy attacks.

Bella's team members huddled tightly together, their eyes revealing determination and determination. As the captain, Vela knows the importance of this battle, and he must lead his team to overcome the difficulties ahead.

Bella quickly gave the order to divide the team into two groups and adopt a flanking tactic. They take advantage of their surroundings, look for cover, and minimize the enemy's advantage as much as possible. Bella and his partner Kate led a group and quickly passed through the enemy's lines and launched an attack on the enemy's rear. The other group is responsible for pinning down the enemy and not giving them a chance to counterattack.

Bella and Kate's cooperation is incomparable, they cooperate with each other, both offensive and defensive. Bella, with her keen observation and quick reflexes, quickly spotted the enemy's weak points. Taking advantage of the enemy's negligence, they managed to knock out several enemies. However, the enemy was not resigned to defeat, and they launched a fierce counterattack.

Bella and Kate quickly adjust their tactics and adopt a more flexible approach to combat. They no longer engage the enemy head-on, but use the surrounding obstacles and cover to engage in guerrilla warfare. Sometimes they hide in the shadows of buildings, and sometimes they suddenly appear behind enemy flanks and deliver a fatal blow.

The team members also played well, they worked closely together, covered each other, and constantly suppressed the enemy's counterattack. Bella's squad showed excellent teamwork and combat ability, and every action they made was full of tacit understanding and strength.

As the battle progressed, the enemy gradually felt the threat of Bella's squad. They began to mobilize more men in an attempt to suppress the attack of Bella's team. However, Bella's squad did not back down, they held their ground and fought fiercely with the enemy without fear.

Bella and Kate's tactical dexterity confuses the enemy, who are unable to predict the next move of Bella's squad. The members of Bella's squad showed extraordinary courage and determination in battle, constantly inflicting heavy losses on the enemy, leaving them in chaos.

The prestige of Bella's squad also spread, and other resistance groups began to move closer to them, hoping to cooperate with them in the fight against the enemy. Vela Squad accepted the request of these organizations, understanding that only by uniting could they defeat a formidable enemy.

Over time, Bella's squad grew in strength. They have access to more resources and support through partnerships with other organizations. They began to carry out larger-scale raids, targeting important strongholds and military facilities of the enemy. The name of Bella's squad gradually became a nightmare for the enemy, and their actions left the enemy at a loss.

The top brass of the enemy began to feel the pressure, and they decided to send an elite unit to eliminate the Bella squad. This force is made up of the enemy's top special forces, who are given the task of destroying Bella's squad.

Bella Squad learns of the enemy's plans, and they decide to take on this elite force. Bella and Kate led the team through a detailed tactical set-up, and they decided to block the attack in an abandoned factory. The factory is surrounded by complex terrain and labyrinthine passages, which will give Bella's squad a great advantage.

The battle begins, and Bella's squad uses various facilities and traps in the factory to constantly cause trouble for the enemy. They skillfully use a variety of weapons and tactics to knock off their enemies time and time again. The members of Bella's squad showed extraordinary combat ability, and their tacit coordination and accurate shooting made the enemy feel unstoppable.

The enemy's special forces were initially unimpressed by the strength of Bella's team, and they confidently entered the factory, ready to destroy Bella's team in one fell swoop. However, they soon realized that they were overestimating their opponents.

The members of Bella's team have a clear division of labor and occupy key positions in the factory. Bella and Kate lead a part of the team to hide in high places, using skylights and ventilation ducts in the factory to snipe. Their shots were extremely accurate, and every bullet hit the enemy's vital point. Others lurk around the factory, using traps and ambushes to corner.

Born out of a laboratory accident in the factory, this zombie possesses extraordinary strength and speed, making it a common threat to enemies and Bella's team. The appearance of zombies makes the whole battle situation more complicated and dangerous.

The members of Bella's squad showed amazing reflexes and combat skills in the face of the zombie's attack. They utilize a variety of weapons and equipment to engage in fierce battles with zombies.

Despite the zombies' extraordinary strength and speed, the members of Bella's team are undaunted and calmly work together to employ a series of sophisticated tactics against this formidable foe.

Captain John led the team to quickly develop a plan. They first used flashbangs and smoke grenades to distract the zombies, and then quickly launched a siege. John and Kate act as fire suppressors, constantly shooting at the zombie in an attempt to weaken it. At the same time, David and Lily use their agility to quickly dodge and attack around the zombies.

Although the zombie is powerful, it does not possess intelligence and only attacks on instinct. The members of Bella's squad take full advantage of this and keep the zombies in a difficult position by constantly changing tactics and positions. They attack from range, engage in hand-to-hand combat, and blast with traps and explosives. Their tacit cooperation keeps the zombies in a passive situation.

However, the strength and speed of the zombies still put Bella Squad under pressure. Their bullets and explosives don't seem to do much damage to the zombies' bodies, and the zombies' attacks are getting more and more violent. The team begins to feel tired and hopeless, and they realize that they may not be able to defeat the zombie with weapons and equipment alone.

In the heat of battle, the members of Bella's team began to think of other solutions. They understand that in order to defeat this powerful zombie, it is necessary to find its weaknesses. Captain Bella decided to lead the team on a more in-depth investigation and research.

They return to the place where the zombies first appeared, looking for clues. In an abandoned laboratory, they found a notebook on experiments with viruses. This notebook details the study of a virus called the "Diseased Body". The virus has been documented to be a highly mutated virus capable of altering the host's genetic structure, turning it into a powerful zombie.

Team Bella delved into the notebook and discovered that the virus mutated by a special enzyme. This enzyme is called a "mutated enzyme" and is able to alter the genetic sequence of the virus, making it more powerful and fast. The team members immediately realized that if they could find and destroy this mutant enzyme, they might be able to weaken the zombies' power.

Bella Team has launched a full-scale search in the hope of finding traces of the mutated enzyme. After several days of searching, they finally found a vial of reagents labeled "mutated enzymes" in an abandoned laboratory. It immediately became clear to the players that this was what they had been looking for.

However, when they try to bring the reagents back to the lab for further research, a group of zombies suddenly appears in front of them. These zombies look more powerful and ferocious than they have encountered before, and their speed and strength are beyond the ordinary. Bella's squad had to engage in a fierce battle with these zombies.

In the fierce battle, the members of Bella's team discovered that the degree of mutation of these zombies was closely related to the mutant enzymes in the reagents. The mutated enzymes in the reagent seem to increase the mutation rate of zombies and increase their strength. The team realizes that they must find a way to neutralize this mutant enzyme as soon as possible, or the zombies' power will become overwhelming.

As they continued their search, Team Bella discovered a study on mutated enzymes. The report mentions that the activity of mutant enzymes can be inhibited by a special herb called "anti-metamorphosis". It is said that the mutatis grows in a hidden valley and only a very few people know about its existence.

Bella Team decides to travel to this valley in search of mutatinous weeds. They traveled through a desolate desert for several days until they finally reached the valley. However, they discover that the change-resistant grass in the valley has been surrounded by a group of zombies. These zombies appear to be even more ferocious, as if they have been controlled by the power of mutant enzymes.

Bella Squad has to fight the zombies once again, using a variety of weapons and tactics to try to defend themselves and collect anti-mutation grass. After a fierce battle, they finally managed to collect enough mutation-resistant grass.

Upon returning to the lab, Team Bella immediately began research on the fight against grass change. They found that the resistance to metamorphosis contained a special compound that inhibits the activity of mutant enzymes. Through further experiments, they succeeded in preparing an antidegenerative enzyme that neutralizes the effects of the mutant enzyme.

Team Bella decides to apply antideviant enzymes to zombies to see how effective they are. They chose a zombie with a high degree of mutation for the experiment, and after injecting the antideviant enzyme, the zombie's strength and speed were significantly weakened, and it became easier to deal with.

After a series of experiments and research, the Bella team finally succeeded in preparing a vaccine against the mutant. This vaccine can inhibit the virus's ability to mutate, so that infected people no longer become zombies. The Bella team handed over the vaccine to a local medical facility, hoping to help more people.

In the process of vaccine popularization, Bella Squad continues to fight zombies and eliminate the source of infection of the virus. They have set up a special unit dedicated to fighting the zombies and the spread of the virus. After a long period of hard work, they finally succeeded in keeping the spread of the virus within a controllable range.

However, there are no detailed instructions for use on the label on the reagent bottle. Team Bella decided to bring the reagents back to the base to find an expert for further analysis. With the help of experts, they found out that this mutated enzyme can only be used in a specific way.

After some research, they found that the mutated enzyme needed to bind to a special antibody in order to work. This antibody is called an "inverter antibody" and it neutralizes the action of the mutated enzyme, rendering it inactive. Bella Team understands that only by finding the inverter antibody can they truly weaken the power of the zombies.

Once again, the team embarked on a painstaking search as they hoped to find clues to the inverter antibodies. By chance, they discovered a scientist who had been involved in the virus experiment. The scientist told them that the preparation of inverter antibodies requires a special plant called "inverter grass".

Bella's team immediately launched a search for the Inverted Grass, and they traveled through a dangerous jungle to eventually find the rare plant in a hidden cave. They brought the inverted grass back to the base for further research with experts.

After a period of hard work, Bella's team successfully prepared an inverter antibody. They combined the inverter antibody with the mutated enzyme and made it into a special agent. The team members are confidently preparing to fight the zombies again.

Just as Bella's squad is in trouble, a mysterious figure suddenly appears on the battlefield. He wears a black cloak and a black mask, making it impossible to see his true face. The figure was armed with a specially crafted weapon, emitting strong energy fluctuations.

The mysterious figure quickly approached the zombie, his movements as swift as lightning, and every attack was accurate. The energy fluctuations from his weapon hit the zombie, causing it to let out a scream. The members of Bella's squad watched in shock, realizing that the mysterious figure might be their savior.

The appearance of a mysterious figure changes the entire battle situation. His attacks keep the zombie back, and his speed and strength seem to surpass the zombie. Seeing hope, the members of Bella's team regained their strength and launched an even more intense attack with the mysterious figure.

However, the enemy did not give up because of the appearance of the zombies. Realizing that Bella's squad was far stronger than they had imagined, they began to mobilize more men and equipment. They used the surveillance system within the factory to try to find the weaknesses of Bella's team and carry out targeted attacks.

The members of Bella's squad were under tremendous pressure, but they didn't back down. On the contrary, they were more closely united in the face of the enemy's attack. They use the equipment and environment inside the factory to create various traps and distractions to constantly weaken the enemy's strength.

The enemy special forces began to feel the pressure, and they constantly adjusted their tactics in an attempt to break through the defenses of Bella's squad. However, the members of Bella's team worked together and carried out their tasks accurately. They used the machinery and tools in the factory to confine the enemy's movement to a small space. The enemy is bogged down and cannot play to their advantage.

The members of Bella's squad not only relied on their skills and weapons, but also showed extraordinary courage and determination. Every member of the team values victory more than their own lives, and they will do whatever it takes to protect their comrades and the completion of their missions. This unity and trust has allowed Bella Squad to take its fighting power to the next level.

As time passed, the enemy's special forces began to feel tired and hopeless. Their numbers are decreasing, but the members of Bella's squad are still energetic and motivated. Bella and Kate lead the team in constant pursuit of the enemy, forcing them to the last floor of the factory.

The final battle began, and the members of Bella's squad engaged in a fierce hand-to-hand combat with the enemy's special forces. Both sides come and go, do your best. The members of Bella's team used their last strength to defeat the enemy one by one. In the end, only one enemy special forces remained, who was already badly wounded, but still stubbornly resisted.

However, the enemy was not resigned to defeat, they adjusted their tactics and intensified their offensive. Bella Squad was under tremendous pressure, and their men were constantly fighting, but they were also starting to experience fatigue and casualties. Bella and Kate realize that they need a more ingenious plan to defeat their enemies.

In the nick of time, Bella Squad decides to use the explosives inside the factory to cause even more damage. They set explosives in key locations and lure enemies into traps. When the enemy entered the core area of the factory, Bella Team detonated the explosives, and the entire factory was instantly turned into a sea of fire.

The enemy's elite forces were completely routed, their equipment and weapons were completely destroyed. Bella's squad took the opportunity to launch a counterattack, and they pursued the enemy and eliminated them one by one. This victory boosted the prestige of Bella's squad once again, and they became heroes of the Resistance.

However, Bella Squad didn't let that stop them. They understand that the enemy will not let them go easily, and they need to keep fighting. Determined to expand the battle to a wider area, Bella Squad began to plan a series of operations aimed at the economic and political centers of the enemy.

However, the enemy is not an idle person. They began to intensify the pursuit and attack of Bella's squad, sending more special forces and senior officers. Bella's squad faced unprecedented pressure and danger, but instead of flinching, they threw themselves into the fight more determinedly.

During a fierce battle, Bella's squad suffered heavy casualties. Kate was killed in a rescue operation, which was a huge blow to Bella. However, Bella didn't have time to grieve, he knew he had to keep fighting, for Kate and all those who fought for freedom.

Bella's squad became more stealthy and cautious in their actions, and they learned to better hide their whereabouts and avoid being tracked by the enemy. They began to carry out more sabotage and crack the enemy's communication system, weakening the enemy's combat power.

As the minutes ticked by, the members of Bella's squad were tired, but they didn't give up. They know that victory can only be achieved if they hold on until the last moment. Bella encouraged the team, telling them that victory was at hand, and that if they held on a little longer, they would be able to defeat the enemy.

Under Bella's leadership, Bella's squad showed tenacious will and unyielding spirit. They constantly defeated the enemy and gradually gained the upper hand on the battlefield. In the end, the enemy was forced to retreat, and Bella's squad emerged victorious.

The joy of victory permeated the hearts of everyone in Bella's squad. They hugged each other and celebrated the victory in this hard-fought battle. Bella was immensely proud, knowing that victory in this battle belonged not only to him personally, but to the entire squad.

However, Bella also knows that the fight is not over. They have only completed this mission, and there are more challenges waiting for them. Bella is determined to continue leading the squad forward and face the battles ahead.

Bella's squad members stood firm at their posts in the face of the onslaught of the enemy. Their mutual trust and tacit understanding allow them to better respond to enemy attacks. Bella encouraged the team to stay calm, concentrate, and not be intimidated by the enemy's momentum.

In the heat of battle, Bella's squad displayed extraordinary combat skills and unparalleled strength. Their every attack was accurate and every defense was as solid as a mountain. Their fighting power has made it more difficult for the enemy than ever before, and their presence has become a nightmare for the dark forces.

However, the enemy does not give up easily. They mobilized more men and strengthened their defence. Bella's squad was under more pressure, but they didn't back down. Instead, they work more closely together, support each other, and work together to deal with enemy attacks.

Bella is a sniper in the alliance who hits a member of the special forces with unerring accuracy. This member was the elite of the enemy, and his death was a huge blow to the morale of the special forces. Bella's teammates also put their strengths to good use, using tactical skills and teamwork to successfully defeat the members of the Special Forces one by one.

However, the leaders of the special forces were not defeated. He is a high-ranking general of the dark Ones, possessing great strength and combat skills. He treats the members of the alliance with cold and ruthless, showing his strength without mercy. Bella and his teammates are feeling the pressure like never before, and their fighting skills can't seem to match their opponents.

Just as the members of the alliance are in a desperate situation, a mysterious warrior appears. He was dressed in a black combat suit and armed with a sword that shimmered with cold light. His presence made the generals of the dark forces feel a little uneasy, but he did not back down. Instead, he took on the challenge of the mysterious warrior.

The battle was extremely fierce, and every encounter between the two fighters was full of killing intimacy. Their strength and skill seem to be evenly matched, and no one has been able to gain the upper hand. Bella and his teammates watched the battle with admiration and admiration in their hearts. They knew that the appearance of this mysterious warrior had given them a glimmer of life.

In the end, the mysterious warrior defeated the generals of the dark forces with a single move. His presence regained confidence among the members of the Alliance, who knew that together they could defeat the dark Ones.

In the ensuing battle, the members of the Alliance showed their tenacity and bravery. They fought a fierce battle against the dark forces and eventually succeeded in destroying the dark forces' stronghold. The dark Ones' power has been completely weakened, and they can no longer pose a threat to the Alliance.

The joy of victory permeated the members of the Alliance, who celebrated their victory. They know that this battle is only part of their long-term struggle, but they also believe that if they are united, they can overcome all odds.
