The successful demonstration of the train led to the beginning of a frenzy of train track laying in the Qin State. People saw the convenience that machinery brings. The huge load capacity can transport materials in one go. And the cost of manpower and material resources is absolutely low.

But some problems followed, and the demand for iron surged. In order to expand the amount of iron mined, smelting also requires a large amount of fuel, and manpower must also increase. All this urgently required Qin to make production adjustments. In particular, new iron ore sites will be developed.

All this is giving birth to the creation of some auxiliary disciplines, geology. Chemistry. Smelting, metals and other small disciplines are more meticulously divided and developed. But it's a pity that all these things that the Qin State is exploring now are advancing in a hazy way. The people of the Qin State seem to have caught something. Little by little, they move forward with their own feelings. The front is always foggy. They can't see clearly, but they're still exploring.

Just at home when these adjustments are being made. The first prisoners of war began to be escorted to Xianyang. People saw an unprecedented victory in the war. The Six Kingdoms only realized at this time that the Qin army had quietly moved. And they don't know anything about it.

The number of prisoners of war is slowly accumulating. The number of prisoners of war captured alive varied from one army to another. The Northern Mengtian Department still escorted an equal number of prisoners of war to Xianyang. And because of the special geographical location of the middle line, the number of prisoners of war captured is not very large. The most is on the southern route. There are too many prisoners of war here. The escort team was in a long line and escorted to Point A and to Xianyang. This is there. The state of Qin would redistribute the main destination of these prisoners of war.

What happened in China, Shang Wen got the exact news through the exchange of letters. At present, the progress of the Qin army is unusually smooth. A cavalry brigade on the central line could no longer be satisfied, and Wang Jian transferred two reserve cavalry regiments in Xianyang to temporarily form a mobile cavalry brigade.

The cavalry raided everywhere. Rarely encountered opponents head-on, they advanced quickly in great depth, and then outflanked tactics in a roundabout way, allowing the Qin cavalry to quickly clear these obstacles on the way to the Yellow River. The infantry followed up in time to clear up some of the problems that the cavalry had missed. Scattered and escaped Yue's people. Even so, there are omissions. According to the original mode of transportation, the supply lines of the Qin army would have been harassed by these Yueclans, but now the transport convoy personnel have issued a large number of muskets. Armed with guns, transporters even carried out small-scale military operations in temporary habitats to hunt down and kill the scattered Yueshi people. They call it hunting.

The hunt was carried out along the supply lines of the Qin army. At first, the Qin army's supply personnel, especially those convoys, did not realize the possibility of harassment of the supplies, and they believed that the Qin army had expelled or killed all the Yue's people. However, some of the remaining Yueshi people began to spontaneously harass the supply lines of the Qin army. The convoy suffered certain losses. A lot of supplies were burned, fodder, served. When these losses were reported to Wang Qian, Wang Jian had to call in a cavalry regiment and an infantry regiment to clean up these pesky Yueshi people.

Shang Wen saw it very sensibly and persuaded Wang Jian not to be transferred, but to order those personnel to carry out military operations on their own. And if necessary, according to the team to which it belongs, a certain arrangement will be carried out. At the same time as the order was given, the warlike temper of the Qin people made them start to take military action on their own. They developed their own dragnet-style investigations. All the Yue people who were caught were executed in the most cruel way, and the corpses were fed to the wolves. Hunting at this stage has a strong vindictive nature. The Qin people, who had mastered advanced weapons, began to sweep spontaneously. In this way, the scattered Yueshi people hidden in the mountains began to be wiped out.

Hunting was also taking place on the southern front, where convoys of convoys harassed on supply lines spontaneously took on the offensive after being heavily armed. However, their opponents are more complicated, including the Qiang people and the Yue people. But they don't care about that. The initial act of revenge makes the hunt very bloody. In particular, those Qiang tribes were bloodbathed by the rear personnel of the Qin people. A large number of innocents were bloodily slaughtered. Such facts are preserved only verbally. There are no official records. And the army is advancing at a rapid pace. They are to accomplish the objectives of the first phase of the war. Advance to the Yellow River. Logistics supplies are sufficient as long as the supplies are delivered. What to do is their business.

The one who most wanted to reach the Yellow River was the Mengwu Division, which was the farthest away from the Yellow River, and the arrival time was the third day of January. In the eighteen days of fighting, this Qin cavalry-dominated army almost rushed forward. They swooped down along the way, and then swept away like a whirlwind. Although the troops were a little tired, the hearty attack made the Qin soldiers fight very happily. Especially this cavalry tactic. They are becoming more and more skilled.

After advancing to the Yellow River, the Mengwu Department found that the Yellow River had unexpectedly melted. They had hoped to take advantage of the bitter cold of late winter to pass through the ice, but now it seems impossible to do so. So they had to look at the river where a large amount of ice was floating and wait for the sappers to arrive. Or look for other places to cross the river. Sappers take a while. Because they left the sappers far behind.

The advance of the central line to the Yellow River was two days later. Their marching routes are mostly mountainous ravines, so the pace is somewhat slow. But as soon as they reached the Yellow River, they began to tentatively choose to cross the estuary. The ice of the Yellow River in this section of the river has not melted. After the temptation. Some troops began to cross the river on a large scale. Towards the other side of the Yellow River, Helan Mountain advanced. The army was slowly pushing forward, and the rear supply stations began to set up supply points on the east bank of the Yellow River. Everything went smoothly.

The Airship Units of the Celestial Army did not participate in the rapid advance, and they were naturally squeezed out by the Army. Their arrival disgusted all the people in the Army. They believe that the Celestial Army is here to pick up ready-made. As a result, although the Celestial Army entered the war zone, they did not have a combat mission, and their hearts were extremely unbalanced and dissatisfied, and in order to be able to fight, they could only participate in hunting operations. Operate with those logisticians. But their massive bodies and sluggish movements. None of the logisticians would be willing to go hunting with them. Because the airships of the Celestial Army will expose the action. The logisticians thought it would be better for the airship to join, but the operation broke down several times. Their view of the Celestial Army is that it is useless to see it. The cheers of the people of Xianyang and the cynicism of the logistics staff made the heavenly army very uncomfortable.
