Steam even the crossbow is unscientific, and even Leo can't imagine what its firing principle is, obviously relying solely on the instantaneous thrust of steam, I'm afraid it will be difficult to make the arrows fired powerful, but if it doesn't rely on steam thrust, then what is the half-human-high steam device behind the annihilator for?

With all the doubts in his mind, Leo carefully observed the equipment on the Annihilator's body.

The Annihilator was dressed in a steam suit, with a pair of glasses that looked like diving goggles on his eyes, and a steam repeater in his hand, which looked very similar to the Gatling gun from the old Earth era that Leo had seen in the Earth Federation's weapons gallery.

Behind the Annihilator was a half-human-tall iron box, the outer shell of which was equipped with some gears of unknown function, and the top was equipped with some meters, pistons, and air outlets, and near the hand there were two regulating hand valves, and from the bottom of the box extended a sealed tube, which was connected to the tail end of the repeater launcher.

While Leo was secretly observing the situation, a soldier of the Kingdom of England with severely corroded skin suddenly emerged from the trench in the distance and ran towards the periphery of the battlefield like crazy.

The movement of the warrior was so great that he had only run a few steps away before he was noticed.

I saw one of the Annihilators shout and make a gesture as if to indicate to his colleagues that this person had been handed over to him, and then he was seen to raise the repeater launcher in his hand and aim it at the mad warrior.

Whoosh, whoosh, whoosh!

Several very faint cracking sounds came from the launcher, and five arrows about twenty centimeters in length were seen pierced into the mad warrior's body.

The barb at the end of the arrow is released while flying, preventing the arrow from penetrating the body and causing more severe tear damage to the target's body.

When the warrior fell to the ground, his body had been torn into pieces by the arrow barbs, and his original shape was completely invisible.

Although Leo had seen the power of the various weapons of the Interstellar Federation, he still had to be amazed by the power of the steam repeater in front of him.

Leo shrank his head back into cover and measured his strength in his heart.

If he was still the body of the original biochemical weapon, this weapon of fire rate would not cause him any trouble, but now although this body is two or three times stronger than ordinary people, it is not strong enough to dodge those arrows that are faster than the sound, once he is exposed, the final result will definitely not be much better than the crazy warrior just now.

Thinking of this, Leo cautiously retreated from the broken bunker to the trench, crouched down, and quickly returned to the place where Nelson and Jason were hiding.

"How's the situation outside?" Nelson hurriedly asked when he saw Leo's figure appear.

Jason also pulled out the corpse from his body, sat up, and looked at Leo expectantly.

"It's bad. Leo shook his head, responded, and emphasized, "Very bad. ”

Then, he carefully told the two of them what he had just seen outside.

Hearing that the situation outside was so dangerous, Nelson and Jason both sat on the ground in some frustration, and their whole bodies became disheartened.

Leo, who felt that the atmosphere was not right, immediately gave the two of them a little more hope, and said: "There is no way to escape now, and when it gets dark, we may be able to find the loopholes in their defense line." ”

Although Leo's words were more like a final consolation, they at least brought a little hope to the two of them and made the atmosphere around them a little better.

At Leo's suggestion, the three of them moved to a trench closer to the edge of the battlefield, not to get a better view of the soldiers of the French Empire, but to avoid the smoke of poison gas.

Now in the trench where the three of them are, the gas smoke is very thin, as long as the skin is not directly exposed, they will not be harmed, and the protection on their bodies will no longer be corroded by the gas smoke, which can make them hold out until tomorrow.

There was still some time before it got dark, and the three of them sat opposite each other, and at Leo's suggestion, they sorted out their outfits again. In the past, because they fled in a hurry, the items they collected were directly stuffed into their pockets, which was nothing in normal times, but it could become a fatal factor after the death of the escape.

For this reason, the three of them carefully sorted out the items on their bodies and rearranged them according to Leo's suggestion, so that the outfits on their bodies became more regular, and the abnormal noise made when walking was much smaller.

After packing up, the sun was gradually sinking in the west, and the sky was getting darker, and Jason, who was a little bored, whispered to Leo in order to pass the time, as if he had nothing to say, "There will be no danger for us to stay here, right? If those guys advance into the trenches, we will probably be the first to be discovered." ”

Leo closed his eyes slightly, adjusting the rhythm of his breathing, recuperating his body and mind, and recovering his strength, while answering Jason's question, "No." Depending on the situation, the troops of the French Empire will not enter the trenches until the gas smoke in the battlefield area has dissipated. ”

"Uh! That's good. After Jason got the answer, he also relaxed a little, and then simply used his backpack as a pillow, fell down and fell asleep, not worrying at all about whether he would be able to find a flaw in the enemy's defense line tonight and escape, completely heartless.

The atmosphere around them fell silent again, and nothing could be heard except for the occasional grinding of metal armor from outside the trenches.

After a while, the sky was completely dark, and I don't know if God was taking care of Leo and them, but the sky was still clear during the day, but now the dark clouds have made up for it, blocking all the starlight and moonlight, making everything under the sky even darker.

At this time, the troops of the French Empire, which surrounded the battlefield, collected a large amount of firewood, and made a firepit to light it according to the distance.

I don't know if it's because he hasn't encountered danger all along, Nelson has become a lot bolder, found a wooden box to put under his feet, quietly stretched his head out of the trench, and flicked his hand twice on the eyes on the mask, like a telescope to see the movement of the French Imperial soldiers in the distance.

Nelson's actions were also watched by Leo, especially the action of adjusting the eyes on the mask aroused his interest, and he also tried to fumble the edge of the mask's eyes according to the position of Nelson's fingers.

Although the touch through the glove became a little inconspicuous, he still felt that there seemed to be a deliberately protruding gear in the frame of the eye, and he fiddled with the gear, and found that the eyes on the mask extended forward and backward like a telescope, making the distant scene gradually clearer.

"What a good thing!" Leo said approvingly, turning his eyes back into place.

Although this pair of glasses is simply a worthless antique in the Earth Federation, it is really commendable to make the glasses so delicate in such an environment now.

"This is a medical device specially designed by the Rock Mechanical Institute for the medical department, which is usually just ordinary glasses, and can be used as a magnifying glass when performing surgery. Nelson shrank back into the trench, just in time to hear Leo's words of approval, so he explained, and then said in a heavy tone: "I took a look at those soldiers of the French Empire just now, and found that they are not ordinary soldiers. ”

"What do you mean?" asked Leo, puzzled.

"They are the direct troops of Duke Dewyn, the eldest son of the Emperor of the French Empire. Nelson explained, gesturing to a part of his waist and saying, "There's the Duke of Devon's coat of arms here." ”

Hearing this, Leo recalled the attire of those soldiers, and quickly found the badge from the information summarized by the system, and confirmed: "Is it the two-headed deer?"

"Yes. Nelson nodded, and said, "If I remember correctly, this is not Duke Derwin's territory, why did his direct troops come here? and he also used imine gas in violation of the continental agreement, isn't he afraid of being questioned by the continental council?"

"These things have nothing to do with us, and it doesn't matter if we know them or not. Leo wasn't very interested in what Nelson said about the secrets that might be related to this war, he was more concerned about other things, "Doctor, since you can recognize at a glance what those people are Duke Derwin's direct troops, then you must know something about them, tell me, what are their abilities, the more we know, the less likely it will be to have accidents later." ”

"Who do you think I am, I'm just a doctor, how can I know about Duke Derwin's army?" Nelson said, smiling self-deprecatingly, and said, "It's just that Duke Derwin's direct troops are also among the best among the various legions in the French Empire,"

As he spoke, he paused, as if there was something unspeakable, but after thinking about the current form for a while, he finally spoke, and said: "My classmates in medical school once mentioned that the medical school and Duke Dewin had a cooperation to invent a drug for Duke Dewin that could stimulate the potential of the human body, but in the end it seemed to fail, and only a defective product was produced. ”

When Leo heard this secret, he couldn't help but think of the swordsmen who were patrolling back and forth, thinking of them wearing heavy armor, carrying a large shield behind them, and holding a two-handed wide sword in their hands, and it still seemed easy to walk back and forth, which made him think of the medicine in Nelson's mouth.

In the Earth Federation, it is common to use drugs to enhance the potential of the human body, and an ordinary person can eventually have the same physical fitness as a combat cyborg through systematic drug consumption.

Although with the level of technology here, even if the technology tree is not crooked, it is impossible to have the potential medicine as efficient as the Earth Federation, but it is not impossible to create a similar drug.

So, he immediately asked, "Do you know anything about the defective products of that potential drug?"

"I don't know much. Nelson shook his head slightly, then added, "But I've seen the corpse of the experimenter after the failure to use the defective product, and that corpse ...... How do you say that? It's like a monster with muscles. ”

Hearing this, Leo couldn't help but stick his head out of the trench, and by the light of the bonfire, he looked at the sword soldiers patrolling back and forth in the distance, and saw that they were waving their two-handed broadswords like pieces of paper, and he already had the answer in his heart.

"It's really a bit difficult!" Leo frowned, thinking that if those swordsmen did take that kind of drug, then his attack would probably not be fatal to such a person, in that case, it might alarm others and put him in danger.

When Nelson sat back on the ground, the mechanical repeater he had put aside gave Leo a wake-up call, and he quickly had a plan in his mind, and then asked Nelson very seriously, "I remember you just said that you added a poison to the arrow, how effective is that poison?"

"Very strong. Nelson said confidently, but seemed to feel that he was overly talked, and added: "The drug is very effective, but for ordinary people, I have not tested it on people with special circumstances." ”

"What happens if this powder is burned, does it lose its effect?" asked Leo again.

"Will the effect of the medicine be affected...... Nelson quickly replied, and then he was stunned, as if he had thought of something, looked at Leo, and asked, "Do you want to throw these medicinal powders into the fire and make poisonous smoke?"

Leo nodded, asking, "Can it be useful?"

Nelson pondered for a moment, as if considering Leo's thoughts, and after a while, he said, "I'm afraid it will be difficult to produce the effect you want with this mixture of powder, but I can improve the powder so that it can produce an effect by incineration, and it will not weaken the effect too much." ”

Leo showed joy and immediately urged: "Very good, quickly configure it." ”

At Leo's urging, Nelson immediately took out the medicine suitcase, took out a few bottles of medicinal powder and a set of balance weights, carefully mixed these drugs according to the proportioning formula, and it didn't take long for the small half iron box to be filled, and the drugs needed to prepare the poison were also used up at this time.

Leo retrieved a wide-mouth flask from Nelson's medicine box, poured all the medicines into the tin box, and made a blackout tent out of a wooden box and thick cloth.

He took a medical alcohol lamp and boiled some water in the tent. When the water boiled, he extinguished the flames.

Then he stuffed a half-meter-long bandage into a wide-mouth flask filled with poison, poured warm water into it, plugged the mouth of the wide-mouth flask with a soft stopper, and shook the bottle vigorously to let the poison in the bottle quickly dissolve into the water, and the water completely penetrated the bandage in the bottle.

With all this in place, Leo motioned for Nelson to take a break now, lest he run out of strength to escape when he broke through later.

He made a small flag out of bandages, stuck it in the bunker not far from the trench, and then sat back in the trench, quietly watching the small flag that was constantly being blown by the seal.
