"Jason, protect Miss Catherine. ”

Leo, who had been prepared for a long time, gave Jason an order, and immediately rushed out of the room, lit the burqa in his hand, and rushed towards the monster.

When the monster saw someone rushing out, it let out a rapid scream again, and its movement speed increased a lot.

When the two were so close that they were about to collide, the crack that resembled a large mouth instantly widened, as if it wanted to swallow Leo inside.

However, Leo's movements were like that of a cheetah, and his body was so flexible that every bone could writhe, dodging away from the mud monster with a movement and twist that ordinary people couldn't do, just to avoid the other party's devouring, and at the same time, he also removed the flintlock cannon on his back, and without hesitation, he pressed the muzzle of the gun against the monster's body and pulled the trigger.

A loud "boom" reverberated throughout the cave space, spreading into the distance, so that many people in this underground city heard it, and stopped what they were doing and looked towards the place where the sound came from.

Whether the sound of the flintlock cannon would alarm everyone who went underground was not in Leo's mind right now, all he wanted to do now was to kill the monster and survive.

The fireworks that erupted from the barrel of the cannon instantly ignited the mud monster's body, and at the same time, the rapid shooting of steel balls tore apart the monster's already sturdy body, leaving a large hole in its body, passing through the other side and hitting the rocks on the ground, blasting open a small crack.

The sludge monster doesn't seem to feel any pain, and even if its body is torn open, its attack is still slow.

I saw that it didn't turn around at all, and directly produced six tentacle-like limbs from the part of Leo's body closest to it, and swept towards Leo like an octopus.

This kind of attack that can make ordinary people have nowhere to dodge is like a slow motion in the movie for Leo who has entered a perfect control state, and he easily dodged from between the cracks of the attack, and while he was dodging, he threw the burqa in his hand that had been completely burned into the wound on the monster's body that was gradually healing.

Unlike the part of the body that is ignited by the firework of the hand cannon, the burns on the surface of the body have no obstacle for the monster and can quickly recover through self-healing, but the flame burning directly in the body is enough to be fatal to the monster.

Leo had just thrown the fireball made of the burqa into the monster's body, and the next second the monster immediately turned into a burning fire, as if the monster's body was all made of fleasy fuel.

After seeing that the monster was completely ignited, in order to prevent the monster from fighting back to death, Leo immediately retreated sharply, retreated to a safe place, and then stopped.

But soon he realized that he was thinking too much, and it was clear that the moment the monster's body began to burn, the monster was already dead, and now it was only the monster's shell that was burning.

"What is this? How can there be such a monster in the world?" After Leo signaled that he was safe, Catherine walked out of the stone house quickly, stood beside Leo, looked at the fire in front of her, and said with a pale face.

"I'd also like to know what kind of monster this is, and I think the top brass of the Church of Arcanaya should know the answer. As Leo spoke, he asked Jason for another box of Valjean's special ammunition, stuffed it into his hand cannon, and carried it behind his back.

Now, Leo found that the power of ordinary pistols could no longer deal with such monsters, and as for the king and queen, he had not yet been able to master the real use of them, and there were very few special bullets, so he would not consider using them until he had to.

On the contrary, the flintlock hand cannon that he had abandoned before could play a good role in this situation, and the flintlock hand cannon also had more than fifty pieces of ammunition, which was enough for him to use.

"You're saying these monsters were made by Major and them?" Catherine was a little incredulous.

"Actually, you're already suspicious, aren't you? Think about the location, think about who controls this place, and the answer is easy to find. Leo directly uncovers the thoughts that Catherine wants to hide, and makes her face the things she least wants to face.

Although Leo appears to have no idea about the monster's origins and is only guessing based on the current situation around him, he actually knows exactly where the monster came from.

In the underground space not very far from here, after passing through two large city ruins, you will see an area cleared by the Church of Aknaya, where there are dozens of these monsters that look like they have broken down genetically.

The reason why Leo knew that the way to deal with this kind of monster was to ignite the inside of its body with fire, because when he was building a topographic map on the ground, he saw through the spirit net that the priest of the Church of Arknaya in that area was extracting bodily fluids from a captured monster, and accidentally ignited the bodily fluids, instantly burning himself into a ball of fire.

And the monster that was killed by Leo now is likely to be the monster that was drained of bodily fluids before, and it should have escaped while it was in turmoil, but it was very unlucky to meet Leo, who knew everything about it.

However, through the battle just now, Leo has become a little interested in the bodily fluids of this monster, which are not only more flammable than the oil commonly found in this world, but also release much more heat than those oils.

All the oils used in this world are extracted from the fruit of the charcoal tree, and this refined vegetable oil is further processed three times to make oils for different purposes.

Among them, the best processed oil will become industrial oil for some special mechanical needs, the second class will become the smokeless oil used by nobles and wealthy merchants, and the last oil and water residue will become daily oil lamp oil.

As for the first oil originally extracted from plants, it is used in mechanical lubricants because of its non-flammable properties.

However, no matter how much the scientists of this world refine this oil, the ignition point of this oil is somewhat high, and it takes a while to burn completely, and the heat released is also very average, not even comparable to the heat of some charcoal burning.

Just like just now, after Leo lit the burqa soaked in smokeless lamp oil in his hand, he also needed to entangle with the monster, and only after the oil was completely burned could he ensure that the flames would not weaken or extinguish when he threw it into the monster's body.

Today, the monster's bodily fluids exhibit burning properties very similar to the kind of gasoline commonly used in the oil era of the Old Earth in Leo's memory, and it only takes a little spark to burn completely.

Even after the combustion of this bodily fluid, the released gas can be re-burned, just like natural gas.

The emergence of oil has played a role in the evolution of science and technology in the Earth Age, even Leo, a biological weapon that only knows how to fight, is also very clear, once this body fluid can be mass-produced, then it will also represent the end of the world's steam age.

From the previous perception of that area by the spirit network, it is not difficult for Leo to find that the Church of Aknaya has also noticed the bodily fluids on the bodies of these monsters, so it will feed these monsters at any cost, let them survive, and extract the bodily fluids from the bodies of such monsters from time to time.

This made Leo, who had become very curious, want to explore the area and see what secrets were still hidden in this Aknaya Church, which had deviated from its teachings.

However, the problem was that the location of that area was diametrically opposed to where Nelson's group had left, which made it a little difficult for Leo to choose.

While Leo was thinking about things, the monster's body was completely burned to ashes, which were real ashes, and there was no debris left.

Although he felt that it was impossible to find anything useful in the ashes, Leo still habitually rummaged through the ashes.

It didn't take long for him to feel that his habit was really good, for he had found two things in the ashes.

One of them was a pendant carved out of ordinary stone with the coat of arms of the Church of Arconaya, and Leo sensed that this might be a clue and took it out of the ashes.

"Wait! let me see!" Catherine, who still had the shocked expression on her face, saw the stone pendant in Leo's hand, and immediately stopped him, and then without waiting for Leo to respond, she took the stone pendant, put it in front of her eyes by the light of the fire of the wall lamp in her hand, and looked at it carefully, and then with an expression of disbelief, she murmured, "How is it possible?

"What is this?" asked Leo.

"When the church was first founded, there was no one and no money, so in order to give the people of the church an identity mark, Martin asked someone to make fifty badge pendants out of stone, with the coat of arms of Akenaya on the front and the name of the person and the office in the church on the back, and I was the first supernumerary. Catherine tried to calm herself down, and as she spoke, she took out a similar stone pendant from her neck, put it in her hand, and let the two pendants be compared, although there were some differences in shape, but judging from the way in which the badge was carved, it should have been made by the same person.

"Whose badge pendant does it belong to?" Leo asked in a deep voice.

"It was Little Jack's, and his ministry in the church at the time was that of an evangelist. Catherine had a very sad look on her face, and said: "Little Jack is one of my best friends, when he died, I was studying in medical school, Martin wrote about an accident, except for me, among the fifty people who originally founded the church, only he and the three Mason brothers survived, and the other forty-five died, and Little Jack was among them. Martin said that they were all buried," she said, and she said suspiciously, "It stands to reason that their badges should also be buried together, how can they be in the body of this monster?"

"Forty-five?" Leo was stunned for a moment when he heard this number, and immediately ordered the auxiliary brain system to call up the exploration data record of the spirit network, and soon found what he wanted.

The number of monsters in that underground chamber is exactly forty-four, and the current one is forty-five.

It is difficult for Leo, who found out about this, to see it as a coincidence, according to Catherine, it is clear that when Catherine was away from school, Martin and the others discovered something from this underground city, and something happened to them, Martin and the three high priests survived, and the rest of them became monsters.

At this time, Leo suddenly thought of something, so he asked Catherine a little abruptly, "Miss Catherine, did you use your own perfume before?" ”

Catherine didn't understand why Leo suddenly asked such a question, but she nodded and replied, "I've always used it, and my mother passed it on to me when I was very young, saying that it's the family's secret recipe." ”

Hearing this, Leo had a strange look on his face and looked down at the pile of ashes.

Although it was just a guess, Leo vaguely felt that the monster rushed over just now not to attack them, but smelled the unique perfume smell on Catherine's body, evoked memories, and wanted to come over to find Catherine, but then his appearance made things turn a turn.

Leo then asked an even more inexplicable question, "How was the Church of Aknaya developing before you went to medical school?"

Catherine frowned, and the look of doubt on her face was also a lot thicker, but she still replied truthfully: "It's very bad, there were many gangsters in Cage City at that time, and it wasn't what it is now, and our appearance was a group of enemies who divided the territory for them, so something often happened." Martin and the others were also worried that the gangsters would target me, so they would pool the money and find connections to send me to medical school. At that time, I also thought that it would help them if they learned medical skills, so I agreed. ”

Hearing this, Leo already had the answer in his heart.

From Catherine's age, it is not difficult to deduce how many years it took for the Church of Aknaya to grow into the million-strong church it is today.

Under normal circumstances, it would have been absolutely impossible for Martin, a powerless youth at the bottom of the cage city, to accomplish such a feat in a short period of time, but the fact is that they succeeded, and they succeeded perfectly.

So in Leo's opinion, Martin must have used some extraordinary means. For example, the kind of vision psionic ability that he discovered in Catherine's Clinic, or the kind of affinity in him that is beyond the ordinary people, and so on.

And these extraordinary means related to psionic skills should be what they got from that so-called accident, except that some people were lucky enough to gain some abilities, while others were unlucky enough to become monsters.

Thinking of this, Leo clenched his right hand, feeling the second object in his hand that had just been found from the ashes - a bone-like object, he felt that this bone-like object might be one of the causes of the accident, so he gave an analysis command to the auxiliary brain system, and the results of the analysis came out quickly, and it was presented directly in his eyes.

"The remains of an unknown higher species have been found, which can be classified as omega-level higher organisms and cannot be absorbed. ”
