Doomsday: I can see the health bar and kill monsters to get treasures

[Obtain: Fourth-order crystal core, great power*1]

[Obtain: 1th-order crystal core·Charge*]

[Obtain: Fourth-level Crystal Core·Throwing Mastery*1]

This fourth-level lord zombie directly exploded three crystal cores. It should have had four superpowers when it was at the third level, but after being promoted to the fourth level, one of the superpowers merged with awakening, so now it only has three superpowers, and it just happened to explode three crystal cores.

Then came the ball of trophy light, which contained one more thing than Wang Tao had expected.

[Obtain: Fourth-order crystal core, great power*1]

【…】

[Obtain: Strength Potion*10]

[Obtain: Charged Brass Knuckles*1]

[Obtain: Awakening Key*1]

Compared with the third-level loot light ball, the number of potions in the fourth-level light ball has increased by 10 times. Before, there was only 1 bottle, but now there are 10 bottles. Wang Tao discovered this situation when he was hunting fourth-level zombies in Beijing before, so it was not surprising.

Then came the equipment. This time the equipment was two simple-looking black brass knuckles. Wang Tao had never seen this type of equipment in his previous life.

【Charge Brass Knuckles】

[Level 4 (Epic)]

[Durability +400, Attack Power +100, Attack Speed ​​+20%, Power: Charged Heavy Attack (Requires Awakening Energy to activate)]

[Charge Heavy Attack: Consume a certain amount of awakening energy to launch a charge attack. The longer the charge is, the higher the damage.]

The attribute of the brass knuckles made Wang Tao's eyes light up. The attack power alone increased by 100. In the previous life, many fifth-level equipment did not have such strong attack power, not to mention the 20% increase in speed.

Wang Tao had never found a suitable weapon before, but now he finally has one.

However, there is a small problem. That is, this brass knuckle also has a seemingly good ability [Charge Heavy Attack], but this requires awakening energy to activate, and Wang Tao has not awakened. To be more precise, he has not even awakened...

Wang Tao put on the brass knuckles and tried them out. As expected, he was unable to use [Charged Heavy Attack]. However, it was not a big problem. Wang Tao's physique was strong enough, and the basic properties of the two brass knuckles were also very good, which did not affect his use at all.

In addition to crystal cores, potions, and equipment, this fourth-level lord zombie's loot contains an additional physical "awakening key."

[Awakening Key: The key needed for awakening]

Its effect is exactly the same as the secret key in the previous life. This thing is of no use to Wang Tao, after all, he does not need to awaken. But for others, it is a necessity for promotion to the fourth level, so naturally the more the better.

"Meow~"

Taxue skillfully collected the spoils dropped by other zombies in a bag and handed it to Wang Tao.

Wang Tao smiled and touched Taxue's little head, then took a quick look at the spoils, and since there was nothing special, he put them all away.

"Let's go."

Wang Tao picked up Taxue and flew towards the group of zombies in the distance.

……

Wang Tao left the military base in the morning and returned at night.

There were more zombies at night, and he had wanted to continue hunting, since he and Taxue both had night vision, but they had both consumed too much energy. For safety's sake, he decided to come back and have a good rest, as sharpening the knife does not delay the chopping of wood.

Today's harvest was already very good. The number of fourth-level zombies was far more than he had imagined. At this rate, it shouldn't take long for him to be promoted to fifth level.

"Now that you're back, I'll make you a midnight snack!"

Ding Yuqin ran to the kitchen to make a midnight snack for Wang Tao. The others also asked about the situation in the city. If it was not too dangerous, they also wanted to hunt zombies.

"You can go if you want, but you can only go outside the city..."

Wang Tao briefly explained the situation in the city.

With their fighting power, except for the fourth-level lord zombies, they might not be able to defeat the third-level lords and fourth-level elites. Of course, this is the situation where a group of them besiege individual zombies. If it is a one-on-one fight, it is too dangerous and completely unnecessary. After all, the blood volume of humans in this world is too low, and the tolerance rate is very low. Except for Wang Tao, it is better for others to cooperate in hunting zombies.

After hearing what Wang Tao said, everyone was eager to try it out.

"I'll take you there tomorrow."

Seeing this, Wang Tao smiled and said.

"it is good!"

Everyone nodded excitedly. They had never seen a fourth-order zombie before.

The next day, early morning.

When Wang Tao woke up, everyone else had already gotten up and were waiting for Wang Tao to take them to the city.

Just after breakfast, Qu Shilin appeared with a messy hair. Her beautiful eyes were bloodshot, but she looked a little excited.

Wang Tao helped Qu Shilin tidy up her hair and said softly:
"Didn't you sleep last night? Don't work too hard. We have enough time."

When he came back yesterday, he didn't see Qu Shilin. Wang Tao knew she might be doing research, so he didn't disturb her. But looking at Qu Shilin's current state, it was obvious that she hadn't slept all night!

"How can I sleep with such a huge treasure in front of me! But that's not the point. The point is——"

Qu Shilin suddenly took out a glass bottle of medicine from his pocket and handed it to Wang Tao.

When everyone saw this potion, they all showed disbelief in their eyes. Could it be that Qu Shilin has already developed the zombie virus serum?

When Wang Tao saw the potion for the first time, he also thought that Qu Shilin had developed a zombie virus serum suitable for the survivors of this life. However, the zombie virus serum in the previous life was light gold, while this one was light blue. Moreover, its state and taste were different from the serum in the previous life...

"This doesn't give me the feeling that it's the zombie virus serum?"

Wang Tao was a little confused.

"Indeed not. It will take some time to produce the serum, but it is also a good thing - it is a zombie virus vaccine!"

Qu Shilin spoke excitedly.

"Vaccine?" Everyone was a little surprised.

If we understand it literally, serum is mainly used to fight viral infections, help those infected with the virus overcome the disease, enhance the body's immunity and resistance, and speed up recovery.

Vaccines are usually used to prevent diseases. After the vaccine is injected, it will stimulate the body to produce antibodies against such viruses over a long period of time, thereby preventing the occurrence of diseases.

Could this thing prevent the zombie virus? !
"It seems you have already guessed it! That's right, the function of this vaccine is to prevent infection by the zombie virus in advance!"

After getting Qu Shilin's affirmation, everyone's eyes gradually became excited.

Wang Tao was relatively calm. He looked at Qu Shilin and said with a smile:
"Don't keep me in suspense. Tell me in detail what effect this will have."

"Overall, the effect of this vaccine is far inferior to that of serum, but it also has certain advantages..."

After Qu Shilin's careful explanation, Wang Tao finally understood what was going on.

In the previous life, the effect of the zombie virus serum was very strong. If someone was infected with the zombie virus but had not completely turned into a zombie, they could recover in a few seconds after being injected with the serum, and there would be no sequelae. If they had already turned into a zombie, as long as the time did not exceed seven days, they could still be saved with the serum, it would just take a longer time, and there might be some sequelae after being cured.

Finally, one more point is that this serum can also prevent the zombie virus - if the serum is injected into a person who has not been infected with the zombie virus in advance, he will have a temporary virus antibody in his body and will not be infected by any zombie virus within three days.

In this life, the vaccine made by Qu Shilin is not as effective as the serum. It cannot help humans eliminate the zombie virus in their bodies, and it cannot save them from becoming zombies, but it can prevent the zombie virus in a short period of time.

As long as this vaccine is injected into the body of a human who is not infected with the zombie virus, the person will acquire a virus antibody that can last for seven days. During these seven days, the person will not be infected by the zombie virus!
“You won’t be infected by the zombie virus within seven days?!”

"Oh my god, this is amazing! Doesn't this greatly improve our human combat effectiveness?"

"Niu beep!"

"..."

Everyone knew what this meant and excitedly gave Qu Shilin a thumbs up.

The biggest problem for humans in the battle against zombies is not that they cannot defeat the zombies, but that they cannot withstand the zombie virus.

Zombies can be injured at will, as long as their health bar is not zero, they will not die. But humans are different. No matter how strong a human is, they cannot withstand the zombie virus. Once infected, there is only one ending - death! Even if inhibitors are used, it will only change the death penalty to suspended death penalty, and they will still die in the end.

Therefore, when humans fight zombies, they all aim to avoid getting hurt, and they are very cautious, because after all, getting hurt is almost equivalent to death.

But if we have the vaccine made by Qu Shilin, the situation will be different. Anyway, we will not be infected by the zombie virus within seven days, so humans can fight freely! This will greatly increase the combat effectiveness of humans!

"Great!"

Wang Tao also praised sincerely.

Although he didn't produce the zombie virus serum suitable for this life, it was only a few days after all, and Wang Tao didn't expect Qu Shilin to be able to produce it in a few days. But Wang Tao didn't expect that Qu Shilin didn't make the serum, but made the zombie virus vaccine!

If this thing can be used on a large scale in the country, then the end of the world won’t be so scary!
"Hey, it's all thanks to my husband!" Qu Shilin scratched her head, then said to Wang Tao, "I want you to find someone to test the effect of the vaccine. Although I am 100% sure that it is effective, after all, there has been no clinical trial..."

"Okay, I'll go find someone! Let's put our plan of going out to hunt zombies on hold until we've tested the effectiveness of the vaccine."

"it is good!"

The others nodded expectantly.

Wang Tao immediately brought everyone to the command center, found Bai Hao, and told him about this matter.

Bai Hao didn't know that Qu Shilin was researching zombie virus serum. After hearing that Qu Shilin had actually developed a zombie virus vaccine, he began to wonder if he had heard it wrong.

After getting Wang Tao's repeated confirmation that this was the zombie virus vaccine, Bai Hao immediately ordered people to find volunteers.

In order to test the accuracy, Qu Shilin took a total of 100 zombie virus vaccines. The raw materials needed for the vaccine are very common, and there is nothing particularly rare, so she made quite a lot of the first batch of vaccines.

It took some time, but all 100 volunteers were selected.

Wang Tao originally thought that he could just find 100 soldiers, since there was no risk and the soldiers would obey orders. But Qu Shilin said it would be better to find a variety of people so that the test results would be more accurate.

So among these 100 people there are both men and women, young and old, ordinary people and people with special powers... basically they all meet Qu Shilin's requirements.

Lan Yulian brought several doctors and injected vaccines into these people one by one.

This zombie virus vaccine is different from other vaccines. It is very effective. Unlike other vaccines, which may take several days or even more than ten days to take effect, it only takes one hour after injection to be effective.

But everything has a price, and the price of the zombie virus vaccine is pain!

During the injection phase, although it only took a few seconds, even the most determined soldiers turned pale and sweated profusely. Not to mention the others, many of them cried out in pain.

And even after the injection, they will feel sore all over during the one-hour period when the injection takes effect.

Looking at these people's grinning faces, Qu Shilin said a little embarrassedly:

"Well, the potency of this vaccine is a bit strong, but there's nothing we can do about it. Serious illnesses require strong medicine. It's not fatal anyway, so I just have to get through it... But I will continue to improve it in the future and try to reduce the pain..."

"This is already good. Compared with their own lives, it only hurts a little. They can bear it."

Wang Tao said with a smile.

Everyone else nodded in agreement.

Although it may be a bit easy to say, it is also true.

And it has to be said that human endurance is very strong. At the beginning, these people's bodies were very sore, but as time went on, their perception of pain became weaker and weaker, and in the end they even became a little numb.

Finally, after this long hour, the volunteers suddenly felt their bodies lighten and the soreness was gone!
But before they could rest, Lan Yulian and her men injected them with the zombie virus that had been prepared in advance.

Bai Hao and the others stopped talking, watching all this with great nervousness, including Qu Shilin who was staring closely at the volunteers. Although she believed in herself, she was still nervous.

Compared with the zombie virus vaccine, you don’t feel anything when you are injected with the zombie virus. It’s like being bitten by a mosquito and then it’s gone.

One minute, ten minutes, one hour passed, and all the volunteers were fine, without any accidents.

Wang Tao could also clearly see that there was no zombie virus in their bodies, nor were there any impurities added to their bodies.

It is now basically certain that the vaccine is effective, but the incubation period of the zombie virus can be as long as one day. For the sake of the rigor of the test, a final conclusion will be made one day later.

But we can start making vaccines now.

"Whatever you need, our base will fully cooperate! The weather is clear now, so we can continue airdropping. If there are enough vaccines, we can promote them, and then this end of the world may not be so scary!" (End of this chapter)
