The day after the "large-scale military training" order was announced, there was a big move in the Macheng barracks.

Early in the morning, Liu He asked Yan Laosi, Tao Kuan and others to come to the barracks with some narrow wooden signs similar to door panels, ready to conduct the first test on all the soldiers. The name of this test is "visual measurement", and it is a uniform standard measurement using a special instrument.

This kind of rectangular and narrow wooden plank was naturally made by Liu He and the carpenters in the city, and a layer of white silk was pasted on the surface of the flat wooden board, and on the white silk was written a line of lines of different sizes and different directions of the word "mountain". It is said to be the word "mountain", but the shape is strange, because the left and right verticals are exactly the same length as the middle one, and it seems that I have never seen such an unstandard way of writing.

The big and small "mountain" characters that the soldiers saw in their eyes was, of course, not really mountain characters, but the capital letter E. Although Liu He didn't remember the specific specifications and parameters of the standard logarithmic visual power table, he didn't need to detect the visual power of each soldier to one decimal place, he only needed to know which of the visual power of the soldiers belonged to the excellent, excellent, good, qualified, poor, and exceptional.

A soldier with a good or good vision has the basic requirements to act as a scout, an observation post, and an archer, while a soldier with a good and qualified vision meets the basic requirements of all other arms, and a soldier with a poor or poor vision has something to use, but it is not useless. For example, soldiers with poor vision can act as a meat shield for melee combat, holding a knife in one hand and a shield in the other, because they can't see the progress of the battle in the distance, so it will not affect their confidence in battle, and they can concentrate on slashing the enemy who rushes in front of them until the battle is over or they lose their lives.

Twenty planks were erected, several white lines were drawn on the ground, and next to each plank was a person in charge of recording, and next to each white line stood a supervising officer, and the "visual survey" began.

The line farthest from the plank is a slight three steps forward with reference to Murong Ping's visual power, as long as the soldiers who can clearly report the direction of the opening of the word "mountain" on the white silk on this line, it belongs to the excellent visual measurement level, and it is an important reference standard for being selected into the archery battalion in the future, acting as scouts and sentinels.

As long as the soldiers who stand on this line and can clearly report the direction of the opening of the word "mountain" on the white silk, they belong to the excellent visual ability and are a reference standard for the selection of the shooting battalion.

The two white lines in the middle belong to the "good" and "pass" criteria of the eyesight test, and the first two white lines are "poor" and "very poor".

After intense testing, among the soldiers in their early 5,000s in the city, only 23 of them met the standard of excellence, 345 of them attained the standard of excellence, and the number of people who were in the standard of good and qualified was the largest, with more than 4,000 people, and the number of poor and exceptionally poor was even less, and the total number was less than 300. Such test results are in line with the law of normal distribution, and Liu He did not feel disappointed after reading it.

After measuring this, the soldiers were led to ten very dimly lit barracks. The room was specially furnished, with several ropes pulled up on the ground and bells tied to the ropes. Before each soldier entered the house, he blindfolded his eyes with a thick black cloth, and when he entered the house, he took the black cloth down. The soldiers had to cross the rope to pick up an object placed in the corner of the house, and anyone who struck the bell to jingle while walking was almost "blindfolded", which later became known as "night blindness".

Liu He was a little dissatisfied with the results of this test, because almost half of the soldiers had symptoms of "blindfolding". Even among the more than 300 people who have achieved an excellent eyesight test just now, more than 100 suffer from night blindness.

However, Liu He was mentally prepared for such a result, and he knew that because of malnutrition among the soldiers of this era, many of them were acquired temporary night blindness or acquired night blindness, which could be cured and recovered by improving the dietary structure and some simple training, while the congenital night blindness that was really difficult to treat was only a very few.

Even if it is a small number of soldiers with congenital night blindness, Liu He will not give up easily, because an army does not need every soldier to fight at night, soldiers with congenital night blindness, they can serve as chariot soldiers and baggage soldiers, and these two types of troops basically do not move at night.

For how to prevent and treat night blindness in the army in the future, Liu He has already begun to prepare, and has even been secretly unfolding, for example, when dealing with the batch of horse meat a few years ago, Liu He specifically explained that the horse liver must be left, and then chopped into minced pieces and mixed with meals for soldiers to eat.

Eating animal liver is the easiest way to prevent night blindness.

After the night blindness test, more exciting tests followed, which simply opened the eyes of the soldiers in the city.

For example, there is a test item called "fear of heights", which is to set up a shelf several zhang high on the school field, and on top is a platform, and a gong is hung above the platform, and the soldiers who are tested must climb the platform several zhang high, and then stand up, hold a mallet and ring the gong, and then pass the test.

In order to ensure the safety of the test, several layers of fishing nets were pulled up under the high platform, so that the soldiers who accidentally fell down would not fall into cripples and be seriously injured, but at most they would feel panicked.

I don't know what to do, and I was shocked when I tested it. Among the 5,000 soldiers, there are many soldiers who never dare to climb the high platform, at least about 20%!

For these soldiers who suffer from fear of heights, when defending the city and climbing the ladder in the future, it is natural to try to avoid letting them participate, otherwise they will not become soft-footed shrimp one by one? Of course, some soldiers' fear of heights is an emergency one, and in the future, Liu He will deliberately "take care" of them and forcibly break them through some means!

Another test called "reaction speed" seems very simple, that is, a wooden ruler about two feet long, on which are engraved with measurements, the four fingers of the soldier under test are separated from the thumb, in a natural arc, the tester places the wooden ruler vertically near the soldier's tiger's mouth, and then suddenly lets go, let the soldier under test close his five fingers and hold the wooden ruler.

There is a measure on the ruler that clearly reflects where the person is finally holding the ruler. This test is repeated three times, and then the average is recorded in the individual training file.

There is also a "blood sickness test", the method is a bit cruel, that is, the soldier under test holds a sharp knife, scratches on his palm, must see the bright red blood come out and stain the palm red, and then apply and bandage it himself, which is considered to have passed the test.

The reason why this test is a bit cruel is because it hurts! Seeing other people's blood coming out and being scared and fainting, I don't hurt myself, but I can take a knife and give myself such a blow, although it won't hurt my muscles and bones, but it is also lacking in morality!

However, the eldest prince also said very clearly, if a soldier is afraid of even this pain, and he doesn't even dare to look at his own blood, how can he go to the battlefield to kill the enemy in the future?

There are also some tests that are relatively easy, such as "hearing test", "smell test", "memory test", and "breath-holding test", which do not require effort, as long as the prescribed actions are completed according to the tester's requirements.

After these "messy" tests, the tests that truly reflect personal skills were also in full swing in the following days.

The first item is to measure the arm strength, the way is to lift the stone lock and pull the hard bow, who lifts the heavier the weight of the stone lock, the more open the hard bowstring, the better the result.

The second item is to measure waist strength, the third item is to measure weight, the fourth item is to measure speed, and the fifth item is to measure endurance...... Each item has specific methods and uniform specifications of equipment, and I don't know how the eldest prince of Lu Dao figured out these things.

After these tests, the soldiers thought they could take a breath, but the eldest prince organized all the soldiers to test their professional skills. In other words, the various tests that we have done earlier are all basic tests, and this professional test is to examine the current position of soldiers in the same type of arms.

For example, a soldier who was born as an archer will be tested in a professional test to see his shooting performance; Born as a cavalry soldier, the professional test examines mounted archery and horse chopping movements; As a sergeant who was born as a halberd soldier, the professional test examines the formation and the movement of the halberd......

The tests in various places in the camp were in full swing, and several senior staff members in the Gongzi Mansion led a group of city merchants who could read and settle accounts, and they were so busy that they didn't even sleep. In accordance with the method of Gongzijiao, they counted and sorted the results of each test by category, and then made a list of soldiers who performed particularly well and poorly in a single test, which served as an important basis and reference for the next step of re-dividing troops.

In short, this is a very complicated and huge work, and if it were not for some statistical tabulation and calculation methods of Professor Liu He, it would have been difficult to complete in a few months.

When all the test results were sent to Liu He's mansion, the soldiers in the city were given three days to recuperate, while all the officers above the battalion commander remained in the camp and waited to go to Gongzi's mansion to explain and explain the situation.

After some arduous induction and classification, Liu He finally completed the reclassification of the 5,000 soldiers in Macheng, and achieved the maximum degree of suitability for the job.

For example, if a soldier is excellent in the eyesight test, excellent in the arm strength test, does not have "blindfolded birds", does not faint blood, is not afraid of heights, and has good endurance, then he will be trained as an archer seedling in the future. And if this soldier himself is from the bow and crossbow battalion, then he will be sent to the archery battalion to receive comprehensive and systematic intensive training, and it is very likely that he will become a leader above the rank of chief in the future. If this soldier still has a foundation in horsemanship, then congratulations to him, he is very likely to go to Ningcheng to receive Zhao Yun's personal training next!

Another example is a soldier, who was originally a cavalryman, but his performance in the professional skills assessment was very poor, he always missed the target, and his immediate chopping action was also very average, and he had night blindness, but he had good endurance and could bear weight, so this soldier would be adjusted to the sword and shield battalion this time, and he would be used as a training object for hoplites in the future.

There are also some general overall tests, and soldiers who are at the top of a single event, such as those with a particularly sensitive sense of smell and hearing, very fast climbing heights, particularly fast digging tunnels, and particularly good memory, etc., are trained and used as special talents.

For example, soldiers with a particularly keen sense of smell and hearing are grouped together and have them practice how to act as secret sentinels and how to spot and track the enemy.

For example, gather soldiers with particularly good memories and ask them to memorize some strange symbols and codes, and serve as top-secret intelligence translators in the future!

In short, Liu He's practices are tantamount to tapping the potential of soldiers in the army to the greatest extent and basically realizing the optimal ratio of various types of soldiers.
