In the afternoon, Li Yuanru, Zhang Huan and others rushed back to the valley separately.

To Sang Nan's surprise, Li Yuanru actually brought back fifty horses, and when he asked, he found out that Ivan was going to take Li Yuanru to buy horses, who wanted to match the logistics manager Tie Yun heard about their relationship with Jiang Lang, and actually selected 50 war horses from the stable of the match to give them to Li Yuanru.

Sang Nan knew it in his heart, and thought that he would find an opportunity to visit the matching center in the future. If there is the support of the military, it will be of great help to the implementation of his plans in the future.

Zhang Huan brought back a large number of daily necessities and building materials, as well as more than 30 slave laborers. Coincidentally, when he arrived at the bazaar, he was just in time for a group of slaves to trade, and these slaves were cheap, obedient, and unpaid, so Zhang Huan bought them.

At the moment, time is pressed and there are many things, so after the personnel arrived, Sang Nan immediately proposed his preliminary development plan for Spindle Valley to everyone.

First of all, with Li Yuanru as the main body, Gao Ran as the auxiliary, led Qiu Ye, the Double Lion Brothers, the Fu Wei and the members of the Li Battalion to pretend to be horse thieves, named the Blood Feather, with a radius of 100 miles as the boundary, responsible for robbing and co-opting small groups of horse thieves. Although they only have 50 war horses, with the combat effectiveness of the government guards and Li Ying, there should be no problem in dealing with small groups of horse thieves.

Secondly, the dragon and phoenix were combined into dark feathers, with Zhang Huan as the main and Feng Liu as the auxiliary, responsible for exploring and collecting intelligence clues from surrounding forces and other horse thieves.

Third, the establishment of the junior guard with the Sang teenagers as the team, temporarily divided into two squads, the first squad is mainly Sang Yun, the second squad is mainly Sang Yan, and Sang Nan also transferred special personnel from Li Ying and Fu Wei to be responsible for their daily training.

Fourth, the expansion of the Spindle Valley mainly includes barracks, fortifications, and school grounds, which are used for daily rest, and can also be used as fortifications during battles, and at the same time some necessary obstacles, traps, and bunkers need to be set up around the valley and at the mouth of the valley. In addition, referring to the training standards of the Fuwei and Li Battalions, a school yard was built in the valley for the daily training of everyone.

In the area of logistics management, Sang Nan was unexpectedly handed over to Xiao Mi to be responsible. Facing everyone's puzzled faces, Sang Nan smiled, but did not give any explanation. Seeing the little confusion lying beside Sang Nan, with a face full of excitement and showing off his might, everyone could only secretly shake their heads and smile bitterly.

Considering that in the event of a war in the future, casualties will inevitably occur, so the profession of pharmacist is also indispensable in the team. Mei Dongen grew up in the dense forest of Yunling, her ancestors were medicine farmers for generations, and under the influence of her father, she was familiar with herbs since she was a child, and she was quite familiar with pharmacology. Therefore, Sannan decided to temporarily put Mei Donn in charge of the team's future medical security.

May and Sosa are left behind in Spindle Valley. Needless to say, Sosa is currently the master of the second only force after Mei Jingfeng and Zhang Huan, with the two of them sitting in Spindle Valley, plus the young guard, it is enough to deal with the occurrence of the general situation.

In order to quickly improve the strength of the people around him, Sang Nan also made an extremely important decision.

He spent two days sifting through and sorting out the contents of the three parts of the travelogue, the art of war, the refining of the body, and the pharmacy, and recorded them on a processed deerskin scroll. He plans to pass it on to everyone, and while it may seem risky, he can't do that much at the moment.

"The Art of War" was passed on to Sang Yun, Sang Yan, Sang Baixian, and Su Cheng and Su Rou brothers and sisters, that is, the five teenagers who also studied tactical command. Su Cheng and Su Rou are the children of the third aunt Sang Baici. Su Rou is only thirteen years old this year, and she looks quiet and well-behaved, but she didn't expect that there is a crazy belligerent factor hidden in her bones.

The "Pharmacy Chapter" was only passed on to Mei Dongen alone, and as for the prescription, Sang Nan only took out two kinds for the time being, one is a black ointment for treating external injuries, and the other is a golden pith powder for internal injuries, the formulas of these two drugs are relatively less complicated, and they are also urgently needed by the current team. As for the preparation method of other medicines, he planned to take them out and give them to Mei Dongen when he needed them in the future.

The main function of the "Body Refining Chapter" is to strengthen the body, and there is no conflict with the inheritance of martial arts, so everyone can learn it. Out of prudence, Sang Nan did not record this method on the deerskin scroll, but selected 60 people from the young guards, divided them into three groups according to their strength level, and taught them by his own mouth to learn.

In the days that followed, everything went according to the plan and in an orderly manner.

Zhang Huan would take the members of Dark Feather to inquire about information every day, and after he came back, he hid in the house with Li Yuanru, Gao Ran and others, not knowing what they were discussing.

The content of "The Art of War" is not much, and the words are concise, and in a few words, it exhausts the essence of the world's tactics, and the advanced tactical concept makes Sang Yun and the others feel unpredictable. They are all delicate and talented, and they naturally know the preciousness of this set of military techniques, so they close their doors every day, study hard and deduce, and enjoy it, and they also admire and appreciate Sang Nan's selflessness.

Mei Dongen's progress speed was beyond everyone's expectations, within a few days, she memorized all the content in the "Pharmacy Chapter", although she still lacked the corresponding practical experience, but I have to say that she has a high talent in pharmacy, even Mei Jingfeng, who has always been harsh, also felt that Sang Nan had found the right person this time.

60 teenagers also began to learn alchemy under the guidance of Sang Nan, nine postures, Sang Nan decided to teach the first three first, he was more curious, whether the learning time of these teenagers would be shorter, after all, his body was a little abnormal.

He remembered that it took him seven days to learn the first pose, but the boys had learned something he had never expected - no one could complete the first pose in seven days, despite their efforts. But even so, these teenagers can clearly feel the dramatic changes that have taken place in their bodies, especially in strength, speed and endurance. If they continue to develop at this rate, I am afraid that it will not be long before their strength can reach another level. In addition to their excitement, they looked at the short figure that had been guarding their side for the past few days, patiently teaching themselves, and their proud hearts began to change slowly, and their attitude towards Sang Nan also changed from the initial passive obedience to heartfelt respect.

Seeing the changes in the teenagers, Sang Nan was also very happy. The faster they grow, the more power they have. The characteristics of the Fuwei and Li Ying are too obvious, and I believe that they have already attracted the attention of those who have a heart. But because of his age, the young guards are often ignored by all forces, which is the most terrifying thing about them, and it is also the biggest hole card in Sang Nan's hand.

Moreover, Sang Nan also recorded the changes in the symptoms of the teenagers in the learning process in detail, hoping to find out the rules from them, so as to carry out subsequent improvement and optimization, so that it is convenient to promote it among all employees in the later stage, and it will not let people see any traces from it.

At the same time, the expansion of the valley is well underway. With the participation of slave laborers, more than 30 steeple barracks have been built along the mountain walls on both sides of the valley in just a few days. The temperature in the Northern Demon Plains is very low, and these slave laborers use ice bricks as the main building material, and they mix a raw material called alum ene into the melting snow water, and the condensed ice bricks are not only fire resistant, but also have a lot of toughness, which greatly improves the safety of these buildings.

Each barracks has an internal space of about 100 square meters and a height of only 2 meters, which is not only warm, but also stable and sturdy. The heating in the house uses a fuel called white coal, this gray-white lump ore will produce flammable gas when exposed to water, so as long as you dig a hole in the ice and put the white coal into the hole, you can easily ignite it with an ignition, although it is not as high as the heat of coal combustion, it is also a good heating material.

The slaves also took advantage of the valley's scarcity to build more than a dozen low-rise bunkers of various sizes as checkpoints, covered with snow that was almost indistinguishable to the naked eye. Li Yuanru and Gao Ran led people to set up some traps around the valley.

The school yard is planned as a huge field 100 meters square, and the site is surrounded by a huge ice brick wall. Referring to the suggestions of Li Yuanru, Gao Ran and others, the school military ground is planned into different areas, such as speed training area, endurance training area, strength training area, reaction training area, archery training area, riding area, combat training area and so on. Subsequently, the training facilities were also installed one after another, and although it looked a little rudimentary, it was able to carry out some basic training.

Looking at the rolling logs, obstacles, sandbag formations, wooden formations, knife pits, and plum blossom piles in the venue that left a deep shadow on his entire childhood...... The young guards couldn't help but secretly swallow bitter water, and a long-lost sense of familiarity came to their hearts, and it seemed that Li Ying and the guards did not have the slightest intention of releasing water.

In the icy and snowy land of the Northern Demon Plain, the entire Spindle Valley is showing a thriving momentum!

[It's about to be 515, I hope to continue to hit the 515 red envelope list, and the red envelope rain will be able to give back to readers and promotional works on May 15. A piece is also love, and it must be better! 】
