At this time, the military situation is urgent, and Shen Feng does not sell the bond, and immediately replied to Censen: "This copper cabinet is exactly the kind of fire oil used in the defense that we are equipped with in the military prison!"

“What’s up there?”Cen ginseng went to the copper cabinet and pointed to the rough copper pipe above.

Shen Feng said: "The thick copper pipe above is a cylinder, the lower part of the pipeline connected to the oil tank, pull the handle behind the copper pipe, you can pull the oil in the oil tank, when pressing the handle again, you can spray the fire oil from the front tip."

This kind of cylinder, using the pump source, before Shen Feng in Yanzhou City, once did bamboo cylinder to spray Yanzhou stone fat, to deal with those Turkic soldiers!

After that, Shen Feng went to the front of the copper pipe with Cen ginseng to the front of the mouth, only to see that the sharp mouth is slightly hollowed out, which is placed with a piece of continuous smoldering charcoal, when the fire oil is sprayed through this charcoal, it is instantly ignited, and then becomes a fire snake sprayed out!

Listening to this introduction of Shen Feng, and then after looking at a circle of physical objects, Cen Seng understood what the principle of this copper cabinet car that can spit fire, and how it can play a role, and the heart is also amazing.

He never thought that Shen Feng had actually let the artisans under the clouds and his artisans drive out overnight, such a city-guarding weapon they had never seen before: a copper cabinet truck that could spit fire!

At this time, the cloud went to Shen Feng and Cen ginseng, and his face was also with a slightly lighter look, and looked at Shen Feng and said, "Lord, are you satisfied with this weapon production?"

Shen Feng nodded and smiled and said, “Satisfied, of course, satisfied, doing the same thing as I said!”

Censen went to the two of them and asked in amazement, “Lord Li, what is this?”

Xing Yun said: "Last night, Prince Shen told me this thing, and after drawing the drawings for me, I made the craftsmen of the craftsmen camp overnight to open the furnace and melt copper, make the casting of the standard, and finally drove out these more than a dozen spray trains."Now it seems to be working!”

“This is called a train!”Hearing this, he said with deep emotion.

He nodded his head slightly and said nothing more.

The name given to this new weapon was somewhat hasty, so he called him to spray the train, although simple but also very appropriate.

But Shen Feng knew in his heart that this thing was not created by him out of thin air, nor was it his original, but it was based on the design of the afterlife.

This spray train, in the famous soldier's book "Wu Sum," in the later Song Dynasty, there is another name, called the fire oil tank.

According to the original historical development, after the Tang Dynasty, there were five generations and ten countries, and finally the Chenqiao mutiny was launched by the forbidden army general Zhao Qianxian in the following week, replacing the subsequent weekly change to Song, and finally unified the world.

The Song Dynasty established by Zhao Qianxian, which was bound to be opened, and the later generations were called the Northern Song Dynasty.

The book "Wu Sum" is a military work written by the official of the Northern Song Dynasty, and the author was the civil servants of Song Renzong, who had been public and Ding Du, and the two people had been carefully compiled by the emperor's orders for five years.

"Wu Sui" is the first large-scale official repair comprehensive military works in China, is the Song Dynasty before the military works of the master, the book includes military theory and military technology two parts, in addition to the use of military methods, which also a large part of the introduction of the manufacture of ordnance equipment, but also with a detailed pattern, as a professional soldier, Shen Feng has also carefully studied the "Wu Sui" this book.

In Shen Feng's mind, it was also thought that in the martial arts always recorded a city-guarding armor called a fire oil tank, which is extremely applicable in the current situation of Wujun.

Therefore, Shen Feng did not delay, and when he discussed things with the cloud in the workshop last night, he also told him the design and manufacture of this fire oil cabinet, and drew a detailed pattern.

He brought 5,000 skilled craftsmen this time, and all kinds of equipment and raw materials were available, far from comparable before, so the speed of making this ordnance was also extremely fast!

Not only manufacturing, the cloud itself is also moving the brain, to this kind of fire oil cabinet under the wheels and frame, can be pushed by people to move, but also increased the flexibility of use!

Shen Feng saw this improved fire oil tank, his heart is also a surprise!

Shen Feng said to Cen Sen: "Cen joined the army, you can put these spray trains in this urn city, once found that there is a local port, there are soldiers to drill out from the inside, immediately with this spray train to spray the flame, will be able to greatly suppress them!"

Cen Seng immediately nodded, looked at Shen Feng excitedly said: "There is such a spray train, even if the underground reservoir water is insufficient, I do not have to worry too much about the tunnels."

Shen Feng went to the side of the cloud again and looked at him and asked, “I let you prepare the same kind of weapon, are you ready to finish?”

The cloud immediately nodded and replied, “Compared to this train, that kind of thing is much simpler to prepare!”

“Are these medicines ready?”Shen Feng then asked again.

Xing Yun immediately replied: "The necessary medicinal materials were delivered this morning, according to the king's account, our craftsmen's camp is also completed!"

Hearing this, Cen ginseng's heart was even more strange, I don't know Shen Feng and let the cloud make what new weapons equipment came out, and heard what kind of medicine was involved in it, but it was even more puzzled.

Can this weapon be related to medicine?

“Lord, what’s the good thing about you here, take it out and let the officer see?”He looked at him and asked excitedly.

Shen Feng smiled and said, "There is something good, but it is not for you to guard, I have to take it out!"

At this time, beside Shen Feng and others, the stone bombs ejected by the stone throwers were still constantly hitting the walls of the military prison and the ground in front of the gate, making a huge sound.

Shen Feng looked at the crowd and said, "These stone-throwing machines are really annoying, and they can't let them smash stones like this."

After that, Shen Feng turned his eyes to his feet, and did not know how far the other side's tunnels had been excavated, and how far away from the Wushuguan was.

Shen Feng looked at Cen ginseng and said audaciously: "Cen joined the army, and the defense of the military prison was handed over to you."I want to lead out of the gate, except for the guard in Guan, all the military horses listen to my orders to act!"

“Does the king want to lead the way out in person?”He looked at the clasped with concern.
