Seeing that their teammates were instantly engulfed by the flames, the bobcat soldiers were scared and ran harder. However, they felt that it was more and more difficult to breathe. Finally, they only felt dizzy, nauseous and powerless. Finally, all of them fell to the ground, and the spreading flame finally devoured these Bobcat soldiers, leaving only coke on the ground.

The fire did not stop spreading because of the death of these Bobcat soldiers, but continued to spread wantonly in the sewer. Finally, the fire passed through every corner of the sewer. The rapidly spreading flame made the whole underground water channel like a big explosive barrel and rapidly expanding air Everywhere looking for vent, those sewer outlets, become these vent.

From the inside of the city, there was a lot of fire outside the city.

The city, however, was in good order, unaffected by the sewer explosion.

As a matter of fact, Li Yuanhong began to lay out a defense against the city as early as he took the city. Li Yuanhong once invaded the swamp city through the sewer, and of course he would not ignore this sewer.

When Li Yuanhong entered the sewer, he was even more surprised. Where is the sewer, it is clearly a secret underground passage. Let alone walking, even the five meter tall giant zombie can easily walk through the underground.

If the enemy enters the sewer without his knowledge, he may go directly to his command post. At that time, he will kill the commander-in-chief of the city without any effort.

Of course, Li Yuanhong would not let this happen, so Li Yuanhong began to lay out, turning the sewer into a huge trap.

Of course, the mechanism arranged by Li Yuanhong is very common, but it can't be touched or seen. It's very suitable for this sewer. This is biogas.

Biogas itself is the gas produced by the decay of garbage, which is completely integrated with the smell of the sewer. Therefore, after the Bobcats enter the sewer, they do not find any abnormality. However, if the concentration of biogas is too high, people will suffocate. However, these Bobcats wear masks, which makes them perfectly shield the invasion of biogas, but it also makes them miss the opportunity to find traps.

In fact, the existence of high concentration of biogas is not without loopholes. The rats living in the underground are either fumigated or escaped from the place where they feel threatened by death. So when the Bobcats walk into the sewer, they feel very quiet, but they don't pay attention to this phenomenon.

Li Yuanhong filled the whole sewer with biogas, and then set up a thermal imaging monitor at some key points. You know, the sewer is so dark that ordinary monitors can't see anything at all. So when the Bobcats walked into the sewer, Li Yuanhong quickly found out.

Finally, it's the device that detonates the biogas. It's very simple. It's an electronic lighter. It's just electrified They will make electric sparks, such as lighters or gas stoves used before the end of the world. They are very simple and small. The Bobcats did not notice that there was such a deadly thing in the corner of the sewer.

Finally, they wait for their prey to bite. When these SM soldiers get to the center of the sewer and have confirmed that they can't escape from the sewer, Li Yuanhong presses the power switch of the electronic ignition device, which is the source of the "Pa Pa Pa Pa Pa" sound heard by the SM clan leader. However, this is his life telling charm. When he hears this sound, it means that he is dead The door is open.

Li Yuanhong doesn't pay attention to the sewer. Li Yuanhong knows that the animals who invade the sewer are finished.

Even though these orcs are very resistant to burning and their skin is very thick, in the narrow space after high temperature combustion, oxygen is the most lethal. A large amount of oxygen is burned out, and the external oxygen can not enter because of the heat flow inside the sewer. At this time, the sewer is an anaerobic environment. This situation has to be continued after the heat flow of the whole sewer is cooled Believe me, the orcs, they can't hold their breath for that long. That's why the bobcat soldiers finally felt dizzy and nauseous. It was lack of oxygen.

All the Bobcats died in the sewers, but the tiger general and the ogre chief didn't know that. They only saw a column of fire rising in the city, and there was a constant explosion. This made the big leader think that the Bobcats were successful. So he said to the tiger general next to him: "it seems that the mountain cat leader has met the expectations. You are ready to prepare once the city gate is opened, We'll rush in, and I'll take revenge on my three thousand personal guards

"Yes The tiger general saluted and retreated. However, the tiger general was not as happy as the ogre leader. He always thought that the explosion sound in the city was a little strange. The explosion sound seemed to be very rhythmic, and the explosion flame was columnar rather than the mass like the ordinary explosion. The most important thing was that the city lacked the kind of shouts and murders that it should have It's not like a successful attack.

However, he can't be very sure now, so he doesn't dare to confront the big leader. After all, the big leader is eager for revenge now. If there is any words against him, he may be regarded as betrayal to him, and the consequences are very tragic. Therefore, he can only take precautions in advance to prevent him from being caught by the enemy's tricks.The team was soon ready to stop and wait for the gate to open. At this time, I heard the sound of killing at the gate of the city, and the fire appeared. It was obvious that there was a fight.

Hearing the shouting and the fire at the gate of the city, the tiger general was a little relieved, because these things were very suitable for the appearance of a sneak attack. After a while, the gate slowly opened and the soldiers on the wall disappeared.

"Ha ha ha, Captain Bobcat has got it. Let's go to the city. I'll see who dares to take my city!" Exclaimed the cannibal leader excitedly.

"Yes Tiger general is still tight face, he has doubts about everything just now.

"After a while, you will go and tell all the people to be ready to fight at any time. In addition, tell the vanguard troops that as soon as we enter the city, we will immediately control the gate and the wall, so that we can enter, attack and defend." The tiger told the leopard soldier.

"Yes, my Lord!" The soldier took his orders.

After everything was ordered, the tiger general was a little relieved, and then ordered the vanguard troops to set out.

There were only one thousand soldiers in the vanguard army. When the ogre leader saw that there were only one thousand soldiers, he was very puzzled: "general tiger, how can we send only one thousand soldiers?"

"Big leader, the specific situation in the city is unknown now. We must guard against fraud. We will send 1000 soldiers to control the gate first, and then send a large team into the city. In this way, even if there is fraud, we can advance and retreat freely with the back road of the gate." The tiger general said.

"Well, you're right!" On the surface, the ogre leader smiles and praises him, but in fact he sneers at the tiger general: "what can we be careful about? Will the enemy take the initiative to open the city gate and let us in?"

Although he was not used to the wariness of the tiger general, the ogre chief was patient and waited for the outcome of the 1000 Orc soldiers' attack.

The 1000 soldiers were able to attack the city without any obstruction or any attack. The soldiers on the city wall seemed to have disappeared completely.

These soldiers quickly took control of the city gate. However, they did not find any dead body at the gate, but there was a strong smell of blood, which prevented them from investigating the disappearance of the corpse. It was also the bobcat soldiers who were advanced in the city to clean up and leave.

After controlling the city gate, some of these soldiers quickly rushed to the wall. As a result, the wall was empty and the bodies disappeared. However, with the conjecture of the gate, these soldiers relaxed their vigilance and sent a signal to the tiger generals outside the city.

"Look what I'm talking about. The Bobcats are capable. The city gate has been successfully won! I think you are worried too much. What are you waiting for? Attack the whole army and recapture the city in one breath, so that our soldiers can have enough food to eat! " The ogre leader urged.

Now the tiger general has no choice but to order the whole army to enter the city.

The whole team of nearly 5000 people killed the city in a mighty manner. However, the general of the tiger man was always looking around. He always felt that there was something wrong with the battlefield, but he couldn't find anything wrong.

The team soon arrived at the bottom of the city. At this time, the big leader of the ogre faintly heard the cry of killing in the city, accompanied by the light of fire, so he said to the tiger general: "you see, the Bobcats must have been killed together with the rebels in the city. Let's go and support them quickly!"

The tiger general also heard the voice. Now he can't judge whether the city was captured by the bobcat man. At this time, he can only take a look.

So he ordered the troops to kill the city, but at the same time secretly told the soldiers guarding the city gate to keep the gate and not to close it. Otherwise, when their retreat was broken, they would become turtles in a jar.

Hearing the advice of the tiger general, the city gate Officer immediately patted his chest and said, "please rest assured, as long as I have a life, I will ensure that the gate is safe and sound."

"Well, the life of the whole army, please!" The tiger general saluted deeply.

"The general can't use it. I will try my best to guard the gate." That little Orc leader, who dares to accept the tiger general's big gift, quickly help up the tiger general.

"Well, I'm relieved now!" Tiger general see that small leader finally pay attention to this matter, this just rest assured with the big army, to the city to kill.
