A month later, the number of survivors at the base exceeded 500, of which the number of combatants increased to more than 300, and each of the eight combat regiments had seven squads, except for Liu Yun's eighth regiment, which had only six squads. And the new urban area of Hongjiang City has almost been turned around by the fighters of the base, Yan Fei's current level has reached level 28, and the average level of several regiment commanders has reached level 20, Liu Yun's team has often followed Yan Fei, and the level has increased the fastest, and the average level of several women has reached level 25.

And just when Yan Fei was about to rise to level 30 and reach the second turn in one go, a sense of danger appeared in Yan Fei's heart again, I'll take it! This terrifyingly disgusting sense of crisis is too TMD's familiarity, is there a boss in Hongjiang City?

Yan Fei recalled all the fighters to the base, and then sent a reconnaissance team to investigate the situation, and the feedback was that the zombies in the urban area of Hongjiang City were lost overnight! Yan Fei decisively ordered people to climb to the top of the high-rise building to check the whereabouts of the zombies.

After a team ascends to the roof of the elevator building in Furong Spring, a shocking news comes back that the zombies of the whole city are gathering towards the old town!

When he heard the news, Yan Fei knew that the time had finally come! The zombies have finally produced intelligent zombies (Z1), this zombie is gathering its kind through special means, and there is only one survivor base in Hongjiang City, and Z1's goal is definitely his own base!

All the spies were recalled to the base, and one after another orders were issued from Yan Fei's mouth, and the entire base was filled with a tense and depressing atmosphere.

The first bridge of the Wuyang River has been blown up, and the second bridge of the Wuyang River leading from the base to the city has a thick wall, but just in case, Yan Fei ordered to strengthen the wall, and at the same time ordered someone to install explosives on the bridge, these explosives were found from a quarry and have been thrown in the warehouse of the base, and now it can come in handy, in case it can't resist the attack of the corpse tide, then it can only blow up the second bridge of the Wuyang River!

Everything was ready, it was already dark, but the corpses had not appeared for a long time, Yan Fei did not dare to take it lightly, and arranged for a regiment of people to take turns on duty at night, and sounded the alarm at the base whenever there was a situation.

Nothing happened this night, Yan Fei was inexplicable, what were the corpses doing?

Just after breakfast, the system "ding! A voice prompted in his ear: "Warning! Warn! The virus is evolving! Three times the warning sounded in their ears, and the nerves of all the survivors were tensed by the warning, and a sense of restlessness filled the air, and the fear of the unknown made everyone's hearts beat faster.

"Obey my orders, everyone go back to their posts and prepare for battle!" Yan Fei gave an order, and the fighters in the base went straight to the second bridge of the Wuyang River, as long as the bridge was guarded, the base would definitely not be breached!

"Ding! Warning: The virus has evolved successfully, and the system prompts that all human thermal weapons are disabled! ”

"Ding! Warning: ......"

Three times in a row, the warning sounded in his ears, and now that human beings can't even use thermal weapons, this Nima is going to force human beings to death? Fortunately, Yan Fei's base was not laid down by thermal weapons, but all by the skills given by the system, so in the face of this corpse tide, there is at least a chance to save his life.

Soon, a large group of zombies appeared in the eyes of everyone, this group of zombies was walking slowly along the main road, there were zombies constantly emerging in the small alleys in all directions, and then joined the corpses on the main road, the whole team was quite large, and orderly, their goal was very clear, straight to the second bridge of the Wuyang River!

"The first team of the ranged attack team is ready!" Yan Fei ordered. All the combatants, Yan Fei divided them into two teams, two melee teams, and two ranged teams, taking turns to attack to ensure that the combatants had time to recover.

Soon the corpse group entered the attack range of the ranged profession, Yan Fei gave an order, and all kinds of ranged skills fell on the corpse group's heads, and the corpse group was exploded!

After the first team finished casting their skills remotely, they immediately retreated, and changed to the second team of long-range professions to attack, just like that, the two teams of centaurs took turns to attack, and the corpses that were not fast couldn't even get up to the second bridge of Wuyang River for a while! Everyone's hearts slowly relaxed, only Yan Fei frowned, isn't it? Is this what the corpses are capable of?

Suddenly, a sharp roar sounded in the corpse group, and I saw a tall figure appear in front of the corpse group—L1. L1 is stronger than the defense of ordinary zombies, ordinary one or two long-range skills can not completely kill it, often more than 3 skills to destroy it, this time, because there is L1 in front of the corpse group, the corpse group gradually approached the bridge, and began to slowly walk on the bridge!

Everyone began to get nervous, Yan Fei squinted his eyes, looking at the row of L1 in front of him, because the bridge deck was only ten meters wide, there were only a dozen L1s crowded on the bridge, and when the corpses gradually approached, Yan Fei made a move! Under the control of telekinesis, the black iron giant sword took away the heads of countless zombies from the corpse group, and the first line of defense composed of L1 in the corpse group was instantly crushed, and there was an earth-shattering cheer from the base, and the morale soared!

Another sharp roar sounded, and everyone's hearts tightened, and their eyes searched around the corpses, as if they wanted to find out the culprit who made this sound! Grandma's, everyone knows that the one who makes this voice is the commander of the corpse group! But the corpses were so dense that they couldn't find the ghost thing that made this sound for a while.

At this time, the corpse group changed again, only to see one L1 turn around and retreat, just when everyone was inexplicable, I saw these L1 who retreated and returned to the front line of the corpse group, the difference is that these L1 actually have an S1 lying on their arms, what is the situation with this Nima? Not only Yan Fei was puzzled, but everyone also looked at this group of zombies with a puzzled expression.

Another high-pitched roar upset everyone! I saw that this group of L1s collectively raised their arms, and there was an S1 lying on their arms, so I'll strangle it! Human trebuchets? Yan Fei shouted in his heart that it was not good!

"All the melee guys on top of me!" Yan Fei only had time to roar, and saw the L1 collectively wave their arms and throw S1 into the air, and the landing point of all S1 is the wall where the base is built on the second bridge of the Wuyang River, Yan Fei only felt that there was a zombie rain in the sky, dense, and it made people's scalps tingle to watch!

"Fuck Nima!" Yan Fei roared angrily, and his telekinesis instantly formed a huge palm, slapping towards the S1s flying in mid-air! The purpose of this blow is not to kill the enemy, but to shoot these S1s down!

"Boom!" For a moment, the S1s flying in the sky were shot out of a palm-shaped hollow, and then the remaining S1s finally landed on the wall, some S1 hung directly on the wall, and some S1 was pierced by the profession with a long-handled weapon before it landed, but most of the S1 were thrown on the wall and crashed into the crowd of guards, and suddenly there was a scuffle on the wall, and people were constantly killed by S1, and S1 was constantly hacked to death by melee professions.

Yan Fei walked back and forth on the wall, and everywhere he passed, S1's head was flying! Just as the wall was in a scuffle, a large army of corpses finally rushed onto the bridge and headed straight for the brick wall!

"Push S1 down for me!" Yan Fei saw that the situation was a little out of control, and decisively ordered the team members to push the S1 on the wall to both sides, the strength of S1 is not as strong as L1, and even only a little stronger than ordinary zombies.

"Don't stop attacking from a distance! Just attack the corpses, and hand over all the zombies on the wall to the melee class! Yan Fei yelled.

Suddenly, one by one, ranged skills were thrown at the corpse group again, and the progress of the corpse group was blocked again, and the scene returned to the control range!

Another sharp roar sounded, and Yan Fei scolded: "Scream, scream, scream, call Nima?" Those who have the ability to don't TMD will only call, and there is a kind of heads-up! ”

I saw that there was a sudden chaos in the corpse group, and the ordinary zombies in the front row were directly knocked away, and a huge zombie appeared in front of everyone!

L2: Nima! Zombies have evolved again! L2 is an upgraded version of L1, not only is it bigger than L1, but it is also more than twice as powerful! What kind of plane? L1 can evolve into L2, but what about S1? Did it evolve into S2? On a June day, although the sun was shining, Yan Fei felt cold in his heart.

This is a hard battle, there is no way to back down, behind him is the base, it is the last home of the survivors of Hongjiang City, Yan Fei They can't retreat!

"The ranged class destroys the guardrails on both sides of the bridge, and the first purpose of all melee classes is to shoot these L2s down into the river!" In this case, Yan Fei can only think of this way, confronting L2 head-on, and the melee class will definitely suffer heavy losses!

Soon the ranged profession razed the guardrails on both sides of the bridge to the ground, losing the protection of the guardrails, and many ordinary zombies were squeezed off the bridge by L2, Yan Fei's mind moved, forming a huge fist, and slammed into L2 on the left, "Bang!" I saw that the three L2s on the left were knocked back two steps, and they were about to fall, but they were less than one step away from the bridge and stopped! I'll it! It didn't work! Is this L2 made of steel? Yan Fei was extremely depressed.

"Roar, roar, roar!" The L2 collectively roared and ran towards the brick wall in the middle of the bridge, the skills of the ranged profession fell on L2, and it did not play any destructive role at all, occasionally one or two L2 were knocked back a step or two, and soon ran towards everyone again, and in a blink of an eye, L2 came to the wall!

"Xiaoshuang, it's up to you!" Yan Fei shouted in the squad channel.

"You're ready!" Yang Xiaoshuang couldn't wait to cast her skills towards L2 under the wall.

That's right! Skill "Temptation"! L2 is only level 30, and Yang Xiaoshuang is already level 25, and the zombies within 10 levels of the level difference can be controlled by Yang Xiaoshuang!

Soon one L2 was contained, turned around and attacked the same kind around him, then the second L2 was controlled, and the third ...... A total of 6 L2s were controlled by Yang Xiaoshuang and attacked the L2 around them! Chaos began to arise again in the corpses.

"Roar!" The shrill cry sounded again, Nima, and now everyone hated the voice, but they couldn't find the owner who made it! Just when everyone was speculating about what the corpses were doing, they waited for a long time, but there was no movement, or the group of L2 took the lead, playing a game of stacking people under the wall, and the zombies in the back stepped on the zombies in front of them and climbed up hard, trying to climb up the wall, and the melee profession on the wall continued to attack the zombies who wanted to jump on the wall, and the two sides entered a tug-of-war!
