Subsequently, Wu Chengliu and others made various preparations.

Wu Cheng Liu dismantled the natural gas pipeline and made it into a simple flamethrower that can cause great damage to monsters.

The other staff took out two large bags of flour and planned to sprinkle it in the cafeteria, and when the flour in the air reached a certain concentration, it encountered flames and caused a violent explosion.

But no one wants to do that until they have to, and it's food!

And the power of the flour explosion is huge, after the security door is opened, if there is nothing to attract the attention of the monsters, the security door will not be closed.

Once the flour explodes, the pipes in the kitchen will suffer huge damage, which will lead to a shortage of water, gas, etc., which will greatly shorten the life time of the people left behind......

Li Xiaodao took out the frozen half of the pork, and then took a nap with Li Yi and the others, in order to restore his energy.

2:50 a.m.

Li Xiaodao woke up Li Yi and the others, who were already asleep, and said in a deep voice: "Li Wufang and Li Yi are in front of the road, and we are close behind." Remember, our goal is not to kill monsters, but to break out! ”

Wu Cheng Liu said with concern: "Little knife! If you can't do anything, come back, we don't miss your mouths! ”

Li Xiaodao nodded.

Li San stepped forward and calmly opened the security door, and with the crisp sound of the machine, the security door was slammed open.

Monsters poured in like a tidal wave, dripping rancid saliva and baring their teeth and claws.

Li San and Li Wufang burst into cheers in unison, Li Wufang was in front and Li San was behind, slamming into the monsters.

Bang!

The monsters' momentum couldn't help but pause, Wu Chengliu immediately ignited the gas pipe in his hand, and the surging pillar of fire shot towards the monsters, but in a moment, the entire space was filled with a scorching smell.

The monsters are attracted to the fresh flesh and blood, and they don't care about the flames burning themselves.

Li Xiaodao shouted angrily: "Li Liu, throw the pork out!" ”

Li Liu's attributes were normal, but he had just summoned it, full of energy and strength, and he fiercely threw half of the pork into the group of monsters five meters away.

The monsters, smelling the bloody smell of fresh meat, swarmed towards the half fan of pork, and their rush into the kitchen slowed.

Li Wufang and Li San took advantage of the situation to push the monsters outside, and Li Xiaodao followed.

Li Er and Li Liu were behind Li Xiaodao, and each dragged a large bag of white powder.

And Li Yi and Ouyang Chenggong were at the back, and the two of them were holding bone chopping knives and waving them around.

The group squeezed into the monster with great difficulty, and Ouyang Chenggong shouted: "Old Wu, close the door quickly!" ”

Wu Cheng Liu glanced at Ouyang Chenggong and Li Xiaodao deeply, and immediately closed the security door.

At this time, the entire hall was already crowded with monsters, crowded with people, shoulder to shoulder, and airtight.

Li Xiaodao and the others can damage several monsters in one attack!

Because the monsters are too dense, Li Xiaodao and the others have no way to get down, if they want to break through, at least half of the monsters must be killed!

Li Xiaodao sent the dagger into the heads of the two monsters, dodging the splattering rotten blood, and shouted, "Sprinkle the flour quickly!" Sprinkle around, sprinkle far away! ”

Ouyang successfully cut off the head of a monster and stopped: "It's exploded, and we will die too!" ”

Li Xiaodao said eagerly: "These monsters will help us block most of the power, and we will be seriously injured at most!" ”

Hearing this, Ouyang Chenggong did not hesitate, and cut the flour bags behind Li Er and Li Liu with two knives.

Li Er and Li Liu first sprinkled flour around, and when only half of the flour in the bag was left, they immediately threw the flour bag into the distance, and the flour gushed out, and the surroundings were immediately surrounded by white smoke.

But the concentration is not enough! At least half of the canteen must be sprinkled with flour, otherwise, even if it explodes, at most one-third of the monsters will be killed, and then Li Xiaodao and the others will be injured, not to mention, they will still be besieged by the monsters!

Li Xiaodao shouted: "Chop off the limbs of the monster, throw it at the flour, and help spread!" ”

Li Wufang and the others immediately did so.

Li Wufang picked up her thin sword, and a monster's head fell, she threw the monster's head into the distance, and the head passed through the flour-covered area, and the fierce wind carried the flour to other places......

And the monsters' roars, waving arms, and swinging their bodies will also emit a faint wind, which will speed up the spread of flour, but in just half a minute, the entire canteen will be filled with flour.

Li Xiaodao shouted angrily: "It's now, ignite the fire!" Then ignore the monster's attacks and just lie down! ”

Ouyang Chenggong immediately took out a lighter, lit it, and threw it in the middle of the cafeteria.

Li Xiaodao shouted again: "Speed down!" ”

He crouched down first, and the claws of a monster scraped several deep wounds on his face, and another monster bit his shoulder fiercely, and then tore off the bloody flesh, but he did not resist in the slightest.

The same is true for Li Yi and the others, of course, Li Wufang is a little better, her whole body is wrapped in armor, and the monster can't bite it......

Rumble!

The lighter ignited the flour, and the flames quickly flew in all directions, exploding.

The shockwave shattered the surrounding windows, and the shockwave swept over the monsters, who should have been fanned to the ground, but they were too dense, shoulder to shoulder, and each monster had several support points around it, and they just didn't fall!

The flames immediately spread out, setting all the monsters on fire.

The monsters roared and howled, and died with a thirst for fresh flesh.

And Li Xiaodao only felt a faint shock wave hit his body, and then the monsters pressed on him in unison, and the smell of burning, rotting blood, and CO from the incomplete combustion of oxygen filled his nose.

He only felt that his chest was on fire, and he couldn't breathe!

He felt a chuckle in his heart, he didn't expect a breathing problem, and the explosion was short.

However, one molecule of O2 will produce two molecules of CO, or one molecule of CO2, and the explosion of flour belongs to the category of insufficient combustion, which will not only burn oxygen, but also produce CO will temporarily squeeze out the surrounding oxygen.

In addition, the binding ability of CO and hemoglobin is hundreds of times stronger than oxygen, so at the beginning of oxygen recovery, Li Xiaodao and others still can't breathe!

So Li Xiaodao and the others must hold their breath for at least five minutes!

Besides, it's impossible to kill all the monsters in an explosion! So in these five minutes, they must block the monster's attack and keep moving vigorously!

Is this possible? It's simply impossible!

Even a trained diver can't hold their breath for five minutes and still exercise vigorously!

Thinking about this, Li Xiaodao shouted angrily: "Run to the window!" Don't breathe! ”

He chopped off the head of a monster that had grabbed him, then squeezed past the burning monster and moved towards the window.

Those flames burned on him, causing him to convulsive pain, and those monsters who were not yet dead immediately grabbed and bit Li Xiaodao.

Li Xiaodao's action was greatly hindered, he waved the dagger indiscriminately, killing the two monsters, however, more monsters rushed to him desperately, pounced on him, biting, pulling......

The injuries on Li Xiaodao's body were getting worse and worse, and under his strong willpower, he still held his breath and didn't let the damn CO enter his chest and abdomen.

But his injuries are getting worse and worse, and under the dual effects of excessive blood loss and insufficient oxygen, he already feels dizzy, and in half a minute at most, he will faint!

Li Xiaodao knew that his situation was very bad, but his bright brain was already sluggish, and even if he was not sluggish, he had no way to be in such a desperate situation.

Gambit is only useful when the strength of the two sides is not much different, when the difference in strength is too large, in the strong wisdom, there is no way!

Li Xiaodao's eyes were already black, and his chest was twitching like pain, he was about to fall unconscious, and once he was unconscious, he would inevitably be eaten by the monsters!

He tried to stay awake and drag him into a desperate situation, however, his consciousness only slipped into the abyss little by little......

When the explosion came, Li Yi and everyone else did as Li Xiaodao ordered.

When it exploded, Li Yi and other summons rushed towards Li Xiaodao, and they wanted to use their own flesh to block the shock wave that shot at Li Xiaodao and reduce the damage taken by Li Xiaodao.

However, they were one step slower after all, and the monsters had already pounced on Li Xiaodao, gnawing and devouring him.

Even though the smoke and flames blurred their vision, they could know the pain that Li Xiaodao was experiencing through their own pain.

As a summon, and a summon centered on Li Xiaodao, a summon that can throw away their lives for it, their hearts are full of chagrin at their own incompetence.

Especially Li Yi, as the first summon to be summoned by Li Xiaodao, he has the deepest relationship with Li Xiaodao.

He saw all of Li Xiaodao's efforts in his eyes, and he worked together with them.

However, Liu Yaozu has already reached the second level, and as Li Xiaodao's most loyal servant, he is still only the first level!

Still!

He hates, hates himself, and is not angry.

He is angry, angry at heaven and unjust.

Mixed with hatred and anger, a flame appeared from his chest, burned, swelled, and then exploded like the flour that had just exploded!

Rumble!

After the explosion, Li Yi felt a wave of energy swimming through his body, and his exhaustion was swept away.

The pain in him was gone, but under the scorching flames, the pain reappeared, but not as intense as before.

He could feel that the energy traveled to a place, and the muscles in that place would strengthen.

He's upgraded!

Li Xiaodao, who was already unconscious, heard the voice that was neither male nor female in his ears.
