The protagonist ordered most of the soldiers of the Divine Envoy King's Legion to invest in the construction of the combustion chamber.
The planned combustion chamber is located about half a meter north of the parasitic ant nest, where the height of the ground is slightly lower than the entrance to the parasitic ant nest.
The combustion chamber will be located three meters underground, with two channels connecting the combustion chamber from the ground.
One channel is first inclined at 30 degrees from the ground, then turned to an angle perpendicular to the horizontal plane, and is connected to the combustion chamber from the top to be used as a chimney; the other is inclined at 45 degrees downward to serve as an inlet for air and fuel.
The space of this combustion chamber is much smaller than the regular combustion chamber in "Dongyang City", and the four walls are not designed to be waterproof at all, so the difficulty of construction and the amount of work are greatly reduced. Therefore, by the middle of the night, the entire project was completed.
There was also a small group of warriors from the Divine Envoy King's Legion who were ordered to search for the common local horsetail in the moist areas of the valley.
Horsetail grass, also known as Qianfeng grass, file grass, pen grass, pen tube grass, joint grass, etc., is an upright perennial herbaceous plant, generally 0.5 to 2 meters high. It likes to grow in moist places such as river beaches and streams, and widely grows in Temperate and subarctic regions of the Northern Hemisphere.
The protagonist needs horsetail because its stems are hollow and can be used as gas pipes. However, the stems of horsetail have joints, but the joints are closed. The protagonist needs a piece of horsetail about half a meter long, with a dozen nodes in the middle.
The soldiers of the God Envoy Army quickly found the horsetail grass of suitable length. The soldier ants used their jaws and pottery knives to cut off the horsetail grass. Then the soldier ants crawled from both ends into the hollow tunnel of the grass stem with a diameter of half a centimeter. , start from both ends, work in both directions, and use a pottery knife and a large jaw to open up the joint.
After the work was completed, these soldier ants from the Angel King's army worked together to carry the horsetail back to the combustion chamber.
At this time, the combustion chamber has been completed, and a large number of soldier ants are putting hay, dry moss, twigs and other fuel collected nearby into the combustion chamber.
The protagonist instructs the soldier ants to insert one end of the horsetail pipe diagonally into the chimney mouth, and paste the joints with water-containing clay. The other end of the pipe was inserted into the entrance of the parasitic ant nest, and was also tightly blocked with wet mud.
In this way, the horsetail pipe connects the chimney mouth and the enemy's nest, and the middle part is placed on the ground, covered with a thin layer of sand as a fixation.
After the fuel in the combustion chamber was almost piled up, the protagonist ordered the fire to be lit, and then asked the soldier ants to throw some fresh grass leaves, ant droppings and peppercorns into the fire.
Fresh grass leaves are rich in water and are smoking materials like ant droppings. Sichuan peppercorns are the extra secret weapon brought by the protagonist this time.
When the ants were collecting plant seeds, the protagonist found spices such as peppercorns. In addition to being a seasoning, Sichuan peppercorns are also an insect repellent. The pungent smell of burning Sichuan peppercorns is comparable to poisonous gas for ants.
After the combustion chamber was ignited, two teams of soldiers from the God's Envoy Army were left to take turns taking care of the fire and replenishing fuel and smoke.
The other teams established a semicircular defensive position based on the terrain under the huge rock at the exit of the parasitic ant nest, and sent out a large number of scouts.
As the fire burned more and more vigorously, a large amount of smoke and heat began to flow into the horsetail pipes. It could be clearly seen that the pipes began to twist under force in many places, and even the sand covering them was bounced away.
The freshly cut horsetail is still rich in moisture, and it is a whole plant. Its sealing performance is very good. Except for some slight smoke leakage from the wet mud at the two connecting ports, there is no air leakage at other parts.
Although there is a slight air leakage at the connection between the two ends of the pipe, the connection is very strong and there is no need to worry about the pipe being blown away by the hot air. A steady stream of smoke, full of carbon monoxide, carbon dioxide and choking smoke, was poured into the parasitic ant nest.
The protagonist waits patiently, it will take a short time for the poisonous gas to fill the entire enemy nest.
According to the experience of human society, night is the time when people are sleeping soundly. If a fire breaks out suddenly and a large amount of toxic smoke quickly spreads to the entire building, the casualties will be extremely heavy.
For example, the fire in an apartment building in London, England, on June 14, 2017, was fierce and spread rapidly along the exterior walls of the building. The toxic smoke produced by burning a large amount of building materials became the deadliest killer. The total number of victims in the London apartment building fire disaster reached 79.
However, the most advantageous thing for ants when facing this poisonous smoke and dust that appears at night is that most ants do not sleep even at night.
As mentioned before, ants are famous for rarely entering deep sleep, and most of their rest is just taking a nap.
At present, the protagonist has enforced the rule of long sleep at night in "Dongyang City", and the result is that the average life span of the citizens of "Dongyang City" has been significantly increased.
But the parasitic ants obviously don't sleep at night. Most of the parasitic ants are still running underground, doing meaningless energy consumption.
Since they did not fall asleep, they would quickly discover the choking gas and take targeted measures.
Whether this response is based on instinct or directed by wise men like the Great Gold Worker Ant, what the God Envoy King Army has to do is to crush their attempts to resist.
Five minutes, ten minutes... time passed by minute by minute.
Ants have well-developed sensory organs on their feet and can sense the frequency of ground vibrations. The protagonist had long ago felt intensive and panicky vibrations coming from the ground beneath his feet. Now, this vibration is getting closer to the ground, closer to the entrance and exit of the parasitic ant nest.
The horsetail pipe connecting the entrance and exit of the parasitic ant nest is still pumping a steady stream of poisonous gas into the enemy's nest. The wet clay used as a seal has been dried and even cracked. The protagonist has to let the God Envoy King's army continue to transport the wet clay. The joints were strengthened little by little, eventually forming a larger and larger hemispherical mud bag.
Through the changes in the sensors on his feet, the protagonist seemed to see many parasitic ants following the direction of the poisonous gas and arriving at the original entrance and exit. They may have wanted to block the gas pipeline, or they simply wanted to escape to the ground, but under the high concentration of poisonous gas, they collapsed to the ground little by little and could no longer get up.
The protagonist waits quietly. He feels that the parasitic ants will not sit still and wait to be killed. The original entrance and exit are the areas with the strongest poisonous gas. It is unrealistic to reopen the exit from here. However, parasitic ants who are good at digging holes in the soil have the time and ability to open many other escape hatches.
Many scouts of the God's Envoy Army are searching back and forth on the nearby ground of dozens of square meters. Once the enemy's escape exit is discovered, the God's Envoy Army will rush over and eliminate any enemies that appear!
