The Black Shadow Guard was founded with this in mind.

With their enthusiasm and unprecedented enthusiasm, the two are ready to build a unique army of their own, which can be defeated by one hundred enemies and has no taboos! If it is a hidden sword, the divine sword, it can be invincible and invincible! Kill the enemy invisibly!

In order to conceal the identity of the army, they took in homeless children from all over the country, both boys and girls.

At that time, nearly 10,000 or so children were found, each between the ages of 10 and 15, and they asked the best master they could find to teach them martial arts, all kinds of killing techniques, as well as business, making weapons, and so on, so that those who could not make it to the end would be of other use.

In a few years, almost to the limit of the human body's training, some children unfortunately lost their lives halfway.

In addition to letting them train, in order to be able to improve their combat effectiveness, Situ Yu had to go to actual combat, and in some places in the territory of the Dayi Dynasty, there were often bandits, they were located in remote areas, occupying the mountains as kings, and often robbed rich merchants and high-ranking officials who passed by, and also oppressed the people, which made people miserable.

Situ Yu put the actual combat practice of the shadow guard on these people. Starting from the nearest place, one mountain after another, one thief's den next to another, when the people and the government were still sighing about how the thieves were like evaporating and couldn't find anywhere, the shadow guard had already moved to another place.

And the government couldn't find any clues about who killed the bandits, because there was no way to find out, and in the end they were all gone.

In this way, the shadow guard is trained to be indestructible and omnipotent!

Natural sacrifice is also inevitable, and every sacrifice will make the two of them feel distressed and sad for a long time, and there are less than 5,000 children left in a few years of about 10,000. These 5,000 children have their own strengths, and they are all elites who can survive various trials.

After meditating and screening, only two thousand children with the best martial arts skills were left to form the Black Shadow Guard.

The other 3,000 or so people were arranged to run their own things everywhere, and the countless gold and silver treasures seized from the thieves' den were used by Situ Yu to develop a commercial chain of his own, and the Datong Silver Horn that runs through the entire continent, not only the Dayi Dynasty, but also other countries, the land of barbarians, the land of the Mengren, and some small places, as long as there is a place for their commercial activities, there is a Chase Silver Horn.

There are also inns, grain numbers, etc., which have been developed to many places.

They also had their own arsenal specializing in building weapons, and at that time, there were those children who were interested in building weapons and were proficient in this, and the bows and crossbows and explosives provided by Xiao Tao to Situ Yu were processed by themselves.

And now the Shadow Guard almost every man has a small bow and crossbow. Because of the slight danger of carrying explosives with you, there are special personnel to supervise the transportation, and the manufacture of bows and crossbows and explosives has never stopped in the past few days, and it is being built at an almost unprecedented speed.

When Situ Yu and the others arrived at Jingying, it was already early in the morning, the sky had become clear, and the stars were twinkling in the sky, corresponding to the calm before the storm on the ground!

The brazier in the camp was "crackling", and there was silence all around, and the soldiers patrolling back and forth as usual. As if nothing had happened, nearly 20,000 soldiers were withdrawn from the Beijing camp, and Yin Wanbang did not react at all!
