The boys who are on the defense have all killed the red eyes, they have almost completely given up their individual weapons, some are holding flamethrowers, some are holding bazookas, shooting wildly, the current situation, there is no need to aim at all, they will definitely be able to hit the enemy, those sniper boys standing on the top of the building, they don't need sniper rifles, they directly throw grenades into the sky, in order to kill more zombie birds.

Such a style of play naturally caused heavy casualties.

When the last two groups of students went to the battlefield, the group of students in charge of defense was almost completely wiped out.

Faced with such a situation, many boys even tied grenades to their bodies, ready to rush directly into those zombie fauna and carry out suicide attacks.

Loulan rushed directly to the defense line on the roof, as soon as he entered the battlefield, he immediately judged that the enemy in the sky was the real threat, so he went directly to the roof, opened the bow left and right, picked up the grenade and threw it around, because of the extraordinary physique and arm strength, almost every time he throws, he can say that the grenade just fell to the most dense place of zombie birds, and the maximum number of kills them.

In addition to being physically strong, Loulan also has a fighting spirit necklace to protect her body, although bird zombies have the same contagion as human zombies, but their attack power is much weaker, so even if they are birds, the damage they can cause to Loulan is very limited.

At the beginning, several boys around Loulan were still desperately throwing grenades with him, but later, these guys were directly responsible for the glorious task of transporting grenades to him, because they found that it was more efficient and killed more zombie birds.

Because of the perverted arm strength and accuracy, Loulan almost single-handedly made up for the lack of air defense in the entire school.

The reversal of the tide of battle often starts from an inconspicuous part, Loulan's large number of kills of zombie birds in the sky have effectively reduced the threat from the sky, and the students on the ground can also concentrate on dealing with the enemy in front of them, and gradually, the balance of war has begun to tilt towards the human side.

The fierce battle lasted all night, and the stubborn resistance of the students allowed them to win the final victory, but although they repelled the attack of the zombie fauna, they also lost nearly two-thirds of their manpower, and had to retreat to the Great Hall, using the relatively closed space of the Great Hall to block the enemy from the air, and also lost the outdoor position.

Because of the abandonment of the outdoor position, the electricity and drinking water facilities were quickly destroyed, the entire auditorium fell into darkness, and the teachers and students of the whole school were immersed in the grief of losing their classmates and friends, and the morale was at its lowest point for a while.

However, compared to the outdoors, it is obviously much easier to defend the auditorium, the auditorium has high walls and thick walls, and there are only two entrances and exits, and after repelling the attacks of several groups of animal zombies, the number of animal zombies has also decreased significantly, and the situation has finally stabilized.

After retreating to the auditorium, Loulan was also anxious, under the current situation, if he couldn't come up with an effective way, it would be a matter of time before the entire school would be attacked by zombies, but now he really had no choice.

These days, after Loulan returns to the farm every day, the first thing he does is to check on the situation in the biological laboratory, and then he goes to open up the wasteland, and now his excess income is not used to buy construction and equipment, but to buy seeds and provide diversified food to the school to keep morale from collapsing.

In this way, after spending nearly a month in despair, the biological laboratory finally came up with the results of many days of research, and it was set to an exchangeable state at once:

Pea shooter, you can choose any place to place, after being placed within a radius of three meters (including the air), any close zombie creatures will be attacked, after being attacked by the pea shooter, the zombie creatures will soon be transformed into a vassal plant of the pea shooter, helping the pea shooter absorb nutrients, and at the same time have the effect of expelling zombies and purifying the environment.

"Pea shooter?" Loulan said with some confusion: "Is this thing okay, why does this name sound familiar?" ”

"Hmph, if you can't try it, you'll know" Li Shizhen stroked his snow-white beard and said with a displeased face: "By the way, I heard that there is a bearded man on your farm, and the wine is very delicious." ”

"Bearded? Yes" Loulan said when he heard this: "His wine is not only delicious, it is simply the best, I heard that if you sell it outside, you will need at least ten fantasy treasures in a barrel." ”

"Then you go and get me a bucket," Li Shizhen said lightly when he heard this: "Every day." ”

"What? A bucket a day, you... What's the use of that you wanting? Loulan was a little broken when she heard this: "That thing is very expensive." ”

"Expensive, huh? Okay then" Li Shizhen squinted at Loulan when she heard this, and said with a smile: "Then I'll buy it, you make a price, how much is a barrel." ”

"Buy? What do you mean? Loulan's heart suddenly moved when she heard this: This Li Shizhen seems to be very rich, but the daily maintenance fee of the biological laboratory is only a fantasy treasure, in addition to the necessary expenses, how much salary can the four old men get? If not the salary? So where does their money come from?

By the way, his pea shooter, in addition to the zombie brain crystal, also needs an additional fantasy treasure, which is equivalent to a soft girl coin of 10,000 yuan, this price is not ordinarily expensive.

"I said, Divine Doctor" Lou Lan thought of this, and suddenly said tentatively: "Look at the price of your pea shooter, is it a little expensive, can it be cheaper?" ”

"It's too expensive, of course it can be cheap, but" Li Shizhen smiled slightly when she heard this, and said: "You get what you pay for, it's not impossible to be cheap, but things are different, you have to think clearly." ”

"Then forget it" Loulan hurriedly refused when she heard this, if the doctor cut corners, it would be fatal, and it would never work.

"The bearded wine is very sought-after outside, but we are our own people, so I'll give you half price" Lou Lan continued: "Just five fantasy treasures in a barrel, how about it?" ”

"Five fantasy treasures" Li Shizhen said when he heard this: "No problem, send me a bucket every day, money is not a problem." ”

"No problem, I'll let Britney send it to you every day." Loulan smiled happily, since the cultivation was upgraded, the grain output has doubled, and the wine given to him by the beard has changed from two barrels to four barrels, and one barrel is supplied to Li Shizhen every day, which is not a problem at all.

At this time, Xiao Tiantian suddenly ran over in a panic, and as soon as she saw Loulan, she said:

"Farmer, no, I don't know why just now, the maintenance fee of the biological laboratory suddenly rose by five Fantasy Tongbao per day."

"I'll go, how can this happen?" Loulan was shocked when she heard this, and hurriedly looked at Li Shizhen, but found that this old man was looking at herself with a wicked smile, and his eyes seemed to say: Small, the wool is out of the sheep, don't you understand such a simple truth?

"This, the divine doctor" Loulan said with a bitter face: "Actually, I have always admired the four great divine doctors, and it is also appropriate to honor you with a barrel of bearded wine every day, I think the money is forgotten, this... Free giveaway, free giveaway. ”

"It's for nothing, how embarrassing it is" Li Shizhen smiled when he heard this: "Thank you so much, I still have something to do, so I won't accompany you." ”

As soon as Li Shizhen left, Loulan hurriedly pulled Xiao Tiantian back to the storage warehouse, and asked her to look at the maintenance fee of the biological laboratory, and found that it had really dropped to one dream treasure per day, and couldn't help wiping a cold sweat, and after thinking about it, she said to Xiao Tiantian: "From tomorrow... No, from today onwards, two barrels of bearded wine will be sent to the four divine doctors every day. ”

After discovering that Li Shizhen was able to increase the maintenance fee by herself, Loulan was also scared, so she simply turned one bucket into two buckets.

"By the way, also, send more bars to the old drunken cat, and in the future, it will be a bucket a day." Loulan simply came to a good person to do it to the end.

After arranging the wine, Loulan returned to the biological laboratory, replaced all the remaining crystals in the warehouse with pea shooters, and exchanged a full fifteen pea shooters in one go:

"Anyway, it's finally fruitful, if it doesn't work, just look at it!"

Because it was to be placed in the real world, after Loulan exchanged, he did not experiment directly on the farm, but waited until he returned to school before he began to place the pea shooter.

The best place to place it is of course on the roof of the Great Hall, as long as the Pea Shooter can successfully solve the problem of air defense, then Loulan and they can return to the outdoors, although it is only within three meters of the Great Hall, but the morale boost should also be very huge.

Under the cover of the classmates guarding the entrance of the auditorium, Loulan quickly climbed onto the roof of the auditorium with her bare hands, and directly put a pea shooter on the roof first.

This is the first time Loulan has seen the pea shooter, and found that this thing is about half a meter high, the whole body is green, the bottom part of the long pea stalk is formed into eight conical leaf petals, tightly grasping the ground, on the other side of the pea stalk, there is a funny round-billed pea cannon with a pair of small eyes, which is exactly the same as the pea shooter in the game.

A zombie bird flying in the sky quickly noticed the existence of Loulan, and immediately dived in the air, and flew towards Loulan.
