Shang Wen fell asleep in a trance. The mental stimulation of the day had already exhausted Shang Wen.

In the dream, Shangwen dreamed of a lot of explosives, which were liquid strong nitroglycerin. Shang Wen was so frightened that he didn't even dare to move his feet easily. With just a little collision, these explosives will explode, they are too sensitive. Too sensitive.

Shang Wen felt that the explosives were about to explode, and suddenly woke up. Shang Wen felt that he was sweating all over his body. Some Shang Wen, who had a dry mouth, got up and drank saliva.

Thinking of those explosives, Shang Wen's back felt cold.

Rather than exploring gradually, it is better to make all the information available and avoid these places where explosions can occur. If you explore step by step, I don't know how many people will die. Come to think of it. Write out all the information about the explosives at once. In order to avoid it in time when exploring in the future.

The first is picric acid, which was first synthesized by P. Wolf in England in 1771. It is a yellow crystal, originally used as a yellow dye, and was used in military applications only after it was used in France in 1885 to fill artillery shells. Hence the name yellow explosives. Picric acid is a fierce explosive that was very widely used at the end of the 19th century.

Mercury was invented in 1779 by the British chemist E. Howard. Mercury is an initiating charge that is used in the preparation of fire cap firing and acupuncture charges, and can also be used to fill detonators for blasting.

Nitrocellulose (nitrocellulose): In 1838, T.J. Pellouse first discovered that cotton could explode when soaked in nitric acid. In 1845, the German chemist C. F. Schönbein immersed cotton in a mixture of nitric acid and sulfuric acid to wash away the excess acid and invented nitrocellulose. In 1860, Major E. Ilz of the Prussian Army made the propellant of guns and shells from nitrocellulose.

Nitroglycerin, TNT Dana Explosives, Colloidal Dana Explosives, the world's first bibase explosives. Smokeless gunpowder, special Dana explosives. Black Sorkin, and now the C4 explosive.

The raw materials and formulas of these explosives are all noted in detail. And also wrote a lot of passivation methods, for example, with paraffin, diatomaceous earth, kui earth, etc. Precautions when using explosives, avoid high temperatures, vibrations, etc.

Others, which require the development of the chemical industry, can be discovered one by one. Shang Wen collected the manuscripts and planned to publish them in a simple booklet with top-secret words. After sending it to the printing house for printing, Shang Wen felt that such a research institute should be set up to study it, otherwise, similar incidents would happen. The tragedy cannot be repeated.

The assembly phase of the military exercise is also in full swing. The use of the road was very tight, so Wang Jian had to send his own guards to act as a temporary cameo as a traffic police officer to guide traffic. Cavalry was given priority clearance. The artillery carts were also allowed to enter the road, while the infantry were arranged to travel in two rows on either side of the road. But that still doesn't work. Because this road was also a trade route, it was not built specifically for large armies. I don't want to go north, the highway is divided into two lanes at the beginning.

In desperation. Diversions again. As is the case with the Northern Highway, the road is divided into two halves and the left and right lanes drive up and down. The army mainly occupied one of the lanes, and the soldiers were arranged to drive in a single column. As a result, the speed of traffic is greatly reduced.

In order to improve such a situation. Wang Jian temporarily requisitioned some of the carriages and horses of the carriage and horse company, and asked them to load a regiment of musketeers to move quickly, so that those who could only arrive first in seven days became a musket regiment, a cavalry brigade, and an artillery regiment, depending on the situation of their horses. However, preliminary estimates should be able to reach one artillery regiment. The rest can only walk in tow.

There were not a large number of carriages and horses behind the procurement standards, so Wang Jian had to join a special transport regiment in the establishment of the army, and at the same time, the engineering troops also began to be sent out in advance, they wanted to widen the roads on a large scale, strengthen some bridges, and the engineering troops also began to explore the idea of building an emergency road quickly.

Time is dragging and waning like this. The Qin army was not idle during this time, the second reorganized musketeer division had also completed the redress, and the third musketeer division had already completed the halfway process.

The situation in the north tends to be stable, and at first the Yue army planned a sneak attack, but gradually they found that it was in vain, because there were still a large number of unknown secret posts in the Qin army's defense. The Yueshi army, which suffered some losses, withdrew from the grassland and had to withdraw, and the heavy snow made their logistics very tense, and when retreating, the Yueshi and the Huns looked a little embarrassed. The battle lines of the two sides have temporarily returned to the same stage as at the beginning.

However, the six countries unexpectedly received an invitation to participate in the exercise. This immediately aroused a thousand layers of Lang. The document has explained in great detail that the Qin state is going to mobilize a new army for a large-scale military exercise.

This is the first time that the six countries have heard of such a military exercise. Moreover, they also began to figure out one thing, the Qin State had recently mobilized troops on a large scale and actually established a new army. This army is unlike anything it used to be. The Six Nations panicked.

The most sensitive is the Zhao State, the Zhao army has begun to surround Yandu, as long as an order is given. They could immediately launch artillery to attack the city, and after receiving the documents from the Qin State at this time, King Zhao felt that the Qin State had come from himself for this exercise. Li Mu went to fight Yan Kingdom. The ones who are drawn are all elite. In the direction of Zhao's defense of Qin, it was basically evacuated. The panicked King Zhao ordered the recall of the army three times in a row. Immediately ordered Li Mu to withdraw his troops and return to defense.

The attitude of Korea and Wei was very alarmed, and Qin had not sent a letter to Guguan for a long time. How did a new army come out all of a sudden. And it's right on your doorstep to show you a bold drill.

The whole of South Korea, who are good at scheming, unanimously believes that this is a trick played by the Qin State, and they gather a large army in the name of the exercise, and then let South Korea broadcast vigilance. Take advantage of this opportunity to quickly annex Korea. Thinking of this, the whole of Korea was nervous, and the army was hurriedly recruited into the city for defense. This is the case in South Korea, the same is true for Wei, but Chu is very calm. Their mission, the purpose of the Qin State is Zhao, Han, Wei, and the Three Families, not the Chu State, and the same is true of the Qi State. It's all a cold look. However, it was not a good thing to be lucky enough to see the combat power of the Qin army, so they gladly accepted it.

The happiest is Yan Guo. The whole country of Yan has entered the final stage. King Yan almost even moved the temple to Liaoxi. Received the documents of the Qin State. King Yan didn't know what was going on yet. But the ministers below gave Yan Wang an explanation. King Yan understood that the Zhao army was about to withdraw.
