The whole history of Tang Dynasty, because of the arrival of Shen Feng, has repeatedly reversed the danger, has been greatly changed.

Take the piece of ordnance, because of the arrival of Shen Feng, coupled with the help of the clouds, at this time the Tang army has mastered the black gunpowder and some firearms production method.

The emergence of gunpowder is naturally decisive in military significance.However, from ancient China to the Ming and Qing ’Shiraums, the use of gunpowder and firearms was not very important, and the generals were still the thinking of the cold weapon era.

But since Shen Feng has crossed over, it will naturally make up for this huge historical regret, so that Huaxia will use gunpowder and firearms on the battlefield for hundreds of years!

On the battlefield experienced by Shen Feng, these gunpowder and firearms naturally played a great role, made great progress, and even decided the victory and defeat at the critical moment.In the cold weapons era, the reason why the four-sided array is difficult to break, because all are ground operations, can only be launched face-to-face, like nails on the hard wall, it takes a lot of effort to be able to go deep.

. .

In the hot weapons era, the war is all-round and three-dimensional, for this kind of ground on the military array, the military and horses are dense, I am afraid a simple bombing or shelling can be solved.

For the four strange arrays in front of them, and then think of gunpowder and firearms, at this time Shen Feng can think of several ways to break the formation in his mind.

But at this time, Shen Feng also thought of some special difficulties.

According to Goshuhan, the number of rebel horses used in front of this army was large, and the whole formation was extremely large, and the number of black gunpowder and firearms in their own army was very limited.

After the defense battle of Wujunguan, against the two sets of military horses of He Millennium and Shi Siming, the consumption of black gunpowder and firearms is also very large, and now the amount that Shen Feng can use is not much.

The preparation of black gunpowder is no longer difficult for the cloud, but the supply of raw materials is limited.Sulfur and charcoal are good to say, but the nitrites in it are mainly from Hanzhong and Shudi.Hanzhong is the closest to Chang'an, but the yield of nitrite is not high, and the purity is not high.The quality of nitrite produced in Shudi is the best, but since ancient times.

It is not easy to get out of the Shu, and the transportation is extremely troublesome, making the price strange.

There are naturally other nitrite mines in Datang, but several places are located in the town where Mount Anlu is located, and Shen Feng's side can't be used at all.

With the amount of gunpowder in the current army, it is difficult to break the battle in the form of an explosion attack.But if you first solve that eye, you can achieve a multiplier effect.Shen Feng thought for a moment and looked at the people and said: "The army is surrounded by the city, the form on the other side of Suiyang City is also critical, we can't be stopped by this army, we must break the battle as soon as possible."In my view, before breaking the battle, we must first take away that eye.

. . .

The people nodded slightly, and Goshuhan looked at Shen Feng with doubts and said, “Lord, do you have a way of breaking that eye?”

Shen Feng thought for a moment and looked at the people and said, "There is one way to do it, but tonight I want to explore this army front first."

“What?“Does the prince want to visit in person?”Gossuehan looked at the shock and asked.Shen Feng nodded and said, "It is only if I have seen the whole picture of this army formation with my own eyes and master the position of the eyes, I can know whether my method is feasible, and besides, this time I have a little new idea, or I have to take a good look at that."

Four more to the four!”

“This...”

Listening to Shen Feng say this, Brother Shuhan could not say anything, and he was also concerned about Shen Feng in his heart, saying, "The prince must be careful."

Looking at the look of expectation in Goshuhan's care, Shen Feng said, "Mr. Ge Shu, rest assured, I have a number in my heart."

After that, Shen Feng's eyes swept through the accounts and immediately asked, "Why, has the Lord Yun not yet returned?"

Cen Seng immediately replied, "After the master of the artisans in the camp of the gods and artisans built a good pontoon bridge, he returned to the arms and equipment to be transferred to the other side of the prison, and has not yet returned to the army."

Shen Feng frowned and said, "General Cen, send someone quickly to greet the Lord, now it is time for him to be in the army!"

“At the end of the day!”Cinnamon responded immediately.

"Gentlemen, please return to the camp, so that the soldiers under us can attack at any time!"He said with awe.

“Follow the instructions!”The people in the account will answer loudly, and then leave each other.

Immediately, Shen Feng, accompanied by Cen Seng and Coshuhan, came to the workshop temporarily built by the Shen Artisan Camp in the army.

This workshop is very simple, is the big tent open on all sides, but there are all kinds of tools and objects in it.

Since Shen Feng led the battle, a variety of new ordnance has emerged, and the role of these former ordnance supervisors in the army is becoming more and more important and higher.

Especially after Shen Feng compiled them into a craftsman camp alone, these craftsmen felt more breathless, and sat up things in a comfortable mood and greatly increased efficiency.

After Shen Feng came to the workshop, he found several senior craftsmen and told them in detail what he was going to do.

Although these craftsmen were surprised, they did not say much, because they were in a hurry and immediately began to make it.Now all the materials in the army are sufficient, so that things are made quickly!

Both Gosshuhan and Cen Seng heard such a thing for the first time, and looked at Shen Feng and asked, “Lord, after such a thing is made, it can really be the same as what you say?”

Shen Feng smiled and said, "Of course, this thing I used before I and His Royal Highness Prince conscripted southeast, this time we broke that eye, we must not be separated from such a thing!"

After Shen Feng finished speaking, Brother Shuhan and Cen looked at each other, and were surprised.

For Goshuhan, and Shen Feng have not seen him for a long time, but he saw that he had made a lot of combat skills with the divine weapon army, and he was even more impressed with his wonderful plan.

After a long time, the sun set in the mountains, the sky darkened, and what Shen Feng wanted was finally driven out by the craftsmen of the Gods' camp.

Above a large open space outside the workshop, Cosshuhan and Censeng finally saw this big thing.

It was seen hanging with a tall wooden shelf, with a large bag of cooked cowhide sewn on it, and a wooden basket below, and between the two was a metal barrel like a stove.

In the army, he was somewhat familiar with such a thing, and looked at Shen Feng and said, "Lord, you have made a giant porous lamp!"

He nodded his head: “That’s right!”

The craftsmen of these craftsmen were created by a giant porous lamp and a simple hot air balloon.

The ancient porous lamp can not be manned, but now the hole lamp made, there is a large wooden basket below, standing inside three or four people no problem, and the hot air balloons of the future generations are no different.In the stove that provides heat in the middle, Shen Feng has also improved these craftsmen.The fuel inside is the fire oil used in the army to attack, and the size of the flame can be controlled through the following feng sip, so as to control the rise of the hot air balloon.

Down.

In this way, the difficulty of handling is reduced, and the amount of fire oil in this furnace is too small, which greatly increases the time for hot air balloons.Shen Feng looked at the sky, and the faint outline of the moon had already appeared in the gray sky, and it seemed that tonight was a moon and star of good weather.The wind that comes at night is blowing to the other side of the city, and tonight, too.

And with the excellent night, it is very suitable for using hot air balloons to observe!

Shen Feng looked at Brother Shuhan and Cen Seng and said, "Two generals, after a while the moon rises, let's fly into the sky together!"

Half an hour later, the weather was completely dark.

A round of moons hangs in the night sky, bright as a silver plate, and the sky clouds are thin, making it night, but the line of sight is also very good.

Shen Feng and Coshuhan and Cen joined the big wooden basket under the hot air balloon.

Shen Feng lit the stove with fire folds, and the big bag of cowhide soon began to swell up, and it didn't take long to become a huge hot air balloon.

As the hot air balloon expands, this large wooden basket slowly rises.The craftsmen below untied the cable on the shelf, and the hot air balloon carried the three men into the night sky with Shen Feng!

For Gosshuhan and Censen, this was their first time in the world.

For the ancients, flying was just a dream, something that only the gods could do.And tonight, riding in the huge hot air balloon designed by Shen Feng, Cen Seng and Coshuhan actually flew into the sky!

The two people are difficult to control their excitement, the heart is pounding, looking at the smaller and smaller scenery above the ground, really feel like a dream!

The basket shook slightly in the air, and Cosshuhan and Cen ginseng were a little dizzy, so they clung to the border.

The hot air balloon carried three people along the wind, and soon floated over the four wonders!

Then the bright moonlight, Shen Feng looked down, only to see below is indeed a great army.Although it was already night, the soldiers in the army did not set up camp to rest, and all were on standby.

This is to prevent the Shen Feng side from launching an attack at night, so that the army can operate at any time.

Each of these is a special position, arranged extremely exquisite, Shen Feng from the top down, the heart is also secretly surprised.

Not long after, a large wooden high platform appeared in Shen Feng's line of sight, and there was still the light of the torch.Goshuhan immediately pointed to the high platform and said, "Lord, this should be the eyes of the army."I saw this high platform today, and the flag above it is with a commanding order!”
