When the fierce battle in Longshan was in full swing, Song Ziyu was leisurely reading a book in the tent on the outskirts of the snake-eared settlement.

Yerba mate was boiling in the stove beside him, and green smoke was billowing and thick.

Song Ziyu lay on the chair and flipped through Wu Yao's research notes.

"The incubation period for zombie virus infection is very short."

"Within 5 to 15 minutes of infection, the body temperature of the infected person rises significantly, and the capillaries show blood symptoms, accompanied by dizziness, tinnitus, nosebleeds and many other signs."

"During this time, the patient's perceived temperature will rise rapidly to 40 degrees."

"If there is no targeted antiviral agent, after 15 minutes, the human body will enter the second stage of infection."

"At this time, the body surface temperature of the infected person will reach more than 45 degrees, the body will lose control, and the organs will have bleeding symptoms."

"At this stage, the human body continues to be unbalanced, and eventually the lesion is strongly aggressive."

"At this stage, the body fluids and blood of infected people have begun to carry the virus, and if they come into contact with it, they will cause secondary infection......"

"More than four hours after the infection, the infection enters stage 3."

"At this time, the human body signs are lost, and the ability to move is greatly reduced, until the body enters a state of near death."

"At this stage, human pupils are dilated, the pulse is low, the heart beats down to twelve to fifteen beats per minute, the blood begins to clot and produce a large number of blood clots, and death enters an irreversible stage."

"At this stage, drugs can be taken to delay, and maintaining low temperatures can prolong life for a short time."

……

"The virus has entered the fourth stage, which is the terminal stage."

"At this stage, the patient loses all consciousness."

"The pulse stops, the heart stops, the brain activity stops. The virus begins to invade the body's major organs, especially the central nervous system. ”

"In clinical medicine, death in the physiological sense is declared, and the body is stiff, accompanied by spasms, convulsions and other nerve endings instinctive reactions."

"Within one to two hours of death, the virus takes over the central nervous system of the patient's brain as well as the major organs."

"Three to five hours after the patient's death, the corpse spots disappear, the zombie disappears, the body temperature rises rapidly, and the body begins to tremble without an owner, accompanied by a state of boiling blood."

"The virus tries to reset physical skills by stimulating the nerves in the brain."

"Reboot successful...... Activate the active state. ”

"The respiratory system is replaced by a somatosensory microbial capture system!"

"There is a shift in the way energy is converted."

"Zombies in the nascent stage lack energy replenishment, are very aggressive, and must keep their distance."

……

Song Ziyu put down the medical notes in his hand and couldn't help but sigh.

I have to say that Wu Yao is a talent, and he actually used the method of "clinical medical observation" to record the transformation process of zombies in a rigorous and systematic manner.

This note records in great detail the details of what happened in the process of transforming a person into a zombie after being infected with the zombie virus.

If you hadn't read this note yourself, it would have been hard to imagine that this virus would work on the human body in this way.

Therefore, he will not know what changes are taking place in the snake ear settlement at this moment.

Song Ziyu stood up and took a deep breath, then looked at the snake-eared settlement in the distance.

At this time, although the city gate of the snake-eared settlement was closed, the screams could be vaguely heard.

The heart-rending wails were accompanied by the rapid and brief sound of gunfire.

Song Ziyu closed his eyes, and in his mind, he could even make up the tragic situation inside the snake ear settlement.

According to Wu Yao's medical notes, Song Ziyu could deduce that the first batch of people who drank water in the pond had probably begun to enter a state of corpse transformation.

And the corpse mutation brings chaos and madness.

Song Ziyu has already taken back the drone, and he doesn't want to see the tragic situation of the snake-eared settlement.

But as a qualified leader, Song Ziyu still gave an order for the troops to strengthen the vigilance around the snake ear settlement.

According to his own calculations, the enemy is not only attacked by infection, but also suffers from lack of water.

And themselves, they must make them realize what despair is!

Minutes and seconds pass!

Things are just as you think!

Shortly after the order was given, the door of the Serpent's Ear Colony opened, and someone was sent to try to fetch water from the river.

Song Ziyu knew that they had found that the pond was polluted, and now they had to go to the stream to fetch water if they wanted to draw water.

But I definitely won't give them this opportunity.

There was no need to even give his own order, Qi Dachun and the others who were ambushed by the river had already taken action.

High-end hunters are often presented to others in the form of prey.

Qi Dachun is such a ruthless person.

When the enemy team rushed out to fetch water, he did not fire a single shot, and the pressure of the attack was all given to the others.

When the people of the snake-eared colony, who had been sniped at the cost of their lives, came to the river, he didn't do anything.

He's waiting......

When the first batch of people were ready to go back, Qi Dachun ordered people to do it!

The guns of his soldiers were as crisp as fried beans, and they quickly brought down the people who had come to fetch water.

But Qi Dachun didn't kill anyone!

He's just beating people to the ground running.

This is where Qi Dachun is ruthless!

Imagine a group of people, screaming and wailing by the river, begging their companions to help, and their companions naturally could not give up the buckets at their fingertips, as well as their own companions, so they had to continue to send people to rescue.

And these people who came to the rescue were Qi Dachun's live targets.

Relying on this method of trying to capture the old man, hundreds of half-dead wounded and many more corpses soon piled up on the riverside......

It's miserable!

None of the butchers killed the pigs were so cruel.

Song Ziyu looked at the scene in front of him in the Chinese military tent, and his heart couldn't help but be slightly shocked.

I didn't expect Da Chun, who usually has low eyebrows and kind eyes to himself, to be a ruthless person with deep scheming.

But in any case, this wave of layers of sniper battles, their own side fought very well.

In the end, the enemy lost hundreds of people and did not catch a drop of water.

……

In the snake-eared settlement, Huang Shicheng felt like he was going crazy.

In one day, his situation went from heaven to hell.

The other party did not know what means were used to pollute the water source inside the settlement.

Since early this morning, corpse mutinies have frequently erupted in the settlement!

Countless people were poisoned, eventually turned into zombies, and then began to bite their companions.

If Huang Shicheng hadn't run fast by himself, he was afraid that he would have been eaten by his own infected adjutant!

When he finally led someone to clean up this batch of zombies, the second batch of infections broke out again...... The continuous fighting has caused the settlement to lose its troops, and everyone's morale has reached a low point.

Huang Shicheng couldn't believe that he had lost the initiative on the battlefield in one day and fell into a situation from which he could never recover.

If this pace continues, the settlement of more than 20,000 people will immediately lose its water supply...... The consequences are unimaginable.

You can go without food for half a month, but you can't go without water for three days.

Without water for three days, the fighters will be ineffective.

If you don't drink water for seven days, you will surely die!

At the moment, my top priority is to solve the problem of water sources.

After discussing with Wuqi, Huang Shicheng began to organize troops to prepare to go out of the settlement to fetch water by the river.

Thousands of people were handed out weapons and rushed out.

Then, Huang Shicheng saw what is called a disaster.

……

Outside the tent of the Chinese army, Tang Jian let out a loud laugh.

The essence of this battle was too refreshing, and the enemy was used as a live target to practice marksmanship, and the killing was so loud that it screamed.

"Boss, it's still your scheming that is vicious, and you brought the opponent to the brink of collapse in one day, which is amazing." Tang Jian complimented.

Song Ziyu put down the binoculars and said, "I thought they could endure it for three or five days, but I didn't expect it to collapse faster than I thought." ”

"What's next?" Tang Jian was convinced, like Song Ziyu asked for advice.

Before he knew it, Song Ziyu had established a strong prestige in Longshan's army.

Song Ziyu muttered: "Next, as expected, the enemy will have a reckless counterattack, and we must block their offensive!" As long as this wave of attacks is blocked, the opponent will completely collapse! ”

When the generals heard this, their spirits were lifted.

"I just want a real fight." A newly promoted captain is eager to give it a try.

"I am willing to fight the vanguard, responsible for stopping the enemy's first offensive!" Another captain stepped forward and asked for help.

Seeing that the morale was available, Song Ziyu was quite pleased.

"It's okay, everything is still being calculated!" Song Ziyu looked at the telegram crushed in his hand, his knuckles were a little white, but there was no expression on his face.

At this moment, Song Ziyu got a response from Longshan's side.

The enemy has taken advantage of the surprise attack and has blown up the city walls into the city, and the two sides are engaged in fierce street fighting.

Song Ziyu knew that now the two sides were like a tug-of-war, and no one dared to relax this breath, so the news of Longshan must not be known to anyone.

For this reason, Song Ziyu did not hesitate to shred the telegram and grounded Gongsun Wan'er.

The swords of both sides are against the throat of the other, and it depends on whose life is greater!
