Regardless of the cold, Zheng Feng, together with Zangma and the two housekeepers, came to a tree stump outside, which was the part of the tree roots left by those people after they cut down trees. Zheng Feng's idea was to let the Tibetan horses absorb the nutrients from these tree roots and then transfer them to the crops.

Know that the root part of a tree is not much smaller than the trunk on the ground, and if these nutrients can be used, it will definitely give rise to a lot of food. A lot of trees have been cut down around here now, but there are many more that have not been cut down, and if this is possible, then the massive increase in food can continue for a long time.

Zheng Feng and the two butlers both widened their eyes as they watched as Zangma placed a small seed on top of the large tree stump, and then saw that the entire root part of the tree was withering at a speed visible to the naked eye. After a while, the Tibetan horse bent down and picked up the slightly larger seed, and the root of the tree had become a dead leaf. Zheng Feng raised his leg and kicked the stump, as if it was made of a layer of sand, and the entire tree root was shattered to the ground.

Hehe, Zheng Feng and the housekeepers all laughed, seeing is believing, although as soon as the Tibetan horse came out, Zheng Feng asked him about relevant things, but now that he saw with his own eyes that the nutrients of these tree roots can indeed be absorbed and stored, Zheng Feng is half relieved, and the other half will have to wait for more than a month, and only know the results when the spring starts farming.

That night, although there were only four of them, a very small banquet was held to celebrate the future grain harvest. After the celebration, the horse went to another dwelling, which the stewards had prepared for their new companions.

Although at the second level, there is an additional kind of military tent for the housing, but in fact, it is to turn the house into two floors, and the resources consumed have also doubled. However, the heroes still live in private houses, because the structure of these military tents is relatively strong and airtight, and in terms of comfort and casualness, they are not as good as civilian houses.

After the Tibetan horse moved into the new house, he planted a lot of flowers and plants there, and even in this winter, these flowers still bloomed, which is the convenience of the plant controllers, who can enjoy all kinds of flowers anytime and anywhere.

If this ability is put on the modern earth, it is definitely a cow fork skill for picking up girls, and at the same time, it can also save a lot of money to buy flowers. It's a pity that Nanye-kun is a pure and arrogant boy, and he doesn't seem to have much interest in picking up girls, so he wasted this convenient skill in vain.

However, after seeing those flowers, the housekeepers asked Nanno-kun to place some ornamental flowers in their residence and on the second floor of the commander's mansion, which made this station have a little more scenery in the winter.

After that, the job of the Tibetan horse is to go out every morning, scatter the seeds that can absorb the nutrients, and then on the way back at noon, collect the seeds that have absorbed the nutrients, and after lunch, go out and walk around like this.

The job of the two demon stewards was still to hunt demonic beasts within a radius of fifty kilometers, and the new Ah Fei was responsible for clearing those relatively large stones and clearing the ground for the cultivation that was about to begin.

Ah Fei is the flying shadow in the Youyou, he was originally a half-blood monster of the Snow Maiden, and later transplanted an evil eye to himself in order to find his lost sister. At the same time as the evil eye transplantation was completed, Feiying's original demonic power was also lost, but he later awakened the ability that was opposite to his original innate attributes. This is a typical guy who is cold on the outside and hot on the inside, and is usually cool and silent.

Like Kurama, Flying Shadow is now level six, and his abilities are not complete, and he can't use Black Flame yet, so he can only use superb swordsmanship now. However, Zheng Feng only asked him to remove relatively large stones, and this job was enough as long as swordsmanship.

Ah Fei also went out early in the morning, wandering around for a day, cutting all the big rocks he encountered along the way. The remaining smaller stones were transported back to the warehouse by the people to absorb.

In order to make room for farming, there was more logging work during this period of time than quarrying, so the timber material increased by nearly three million tons, and the stone material also increased by more than two million tons. The corresponding metal also increased by more than 400,000 tons, while the rare mineral increased by 50,000 grams.

It's a pity that the small gold mine has been mined, and although it has added another 500,000 taels of gold, it is not enough to upgrade the standard. After Zheng Feng thought about it, he still asked the Hall of Heroes to create the second-level war group heroes first.

After all, it's hard to say when such things as gold and silver mines will be found again, although the hundred waiters have been created, but the movement speed of these waiters is not as fast as that of heroes, and some waiters have to be left to summon a large number of houses and warehouses, and it is not a matter of a day or two to detect mineral deposits. If you wait like this for the sake of leveling up, it's not a way to keep going, it's better to build the hero first, anyway, the resources of ordinary metals are still quite easy to obtain.

The second-level heroes of the war group can be said to be famous, and there are also two people in this group, they are Wang Jian and Bai Qi in the famous generals of the Warring States. Both of them had the same manufacturing costs, requiring 500,000 tons of grain, 500,000 tons of metal, and 200,000 taels of gold.

Bai Qi's prestige of killing gods can be said to be ferocious, but the incident of killing 400,000 soldiers in the first battle of Changping has been discussed by later generations for thousands of years, but it is also a fact that this battle laid the foundation for Daqin's future domination of the world, so the murderous name and military exploits are equally conspicuous. And Wang Qian, as the first military commander in history to truly unify China, can be said to be a thousand years of meritorious deeds more than this, only talking about military exploits he is more prominent than Bai Qi, after all, although Bai Qi kills a lot, but the territory he gets is not much.

However, if you want to talk about military talent, Bai Qi is probably still slightly better, how to say that he is also one of the four saints of the soldier, and his ability to use soldiers is absolutely strong, but Bai Qi's ending is not very good, his way of life is not as good as Wang Qian's. Although the heroes embodied by the system are not those real people in history, they have also mastered the complete art of war, and as for what the actual combat is, it will have to wait until the time of the war in the future.

When these two come out, there won't be much ordinary metal left in the system, if it weren't for the effective hunting work of the two butlers, and the hundreds of thousands of tons of metal provided by those monsters, there would not be enough resources to make these two famous generals now. Of course, the main harvest of the hunting activities is grain, a total of more than 2 million tons, after excluding this consumption, there are still more than 1 million tons of grain left in the system.

However, the hunting work of the two demon stewards ended here, and the demonic beasts within a radius of fifty kilometers had basically been killed by them. If you go further, you may encounter a fifth-level demonic beast, and if you are unlucky to encounter more than two fifth-level demonic beasts at the same time, then it is still more dangerous, so the hunting activities of the housekeepers end here.

However, the task of hunting Warcraft still has to continue, and the rest of the work will be taken over by these two new heroes of the war group. Just from the manufacturing cost, you can know that they are all sixth-level warriors, and they also have the assistance of small soldiers, so it is much easier to search and fight.

The difference between the heroes of the war group and the combat group is the ability to lead troops, and the gold in their manufacturing costs is specially used to indicate the ability to command troops. The two famous generals' current command ability is 10,000, and the value of these command abilities is about the same as the value of a sixth-level martial artist, but it is not for the sake of looking good, but it has a practical effect.

The units embodied in the system are all incomplete intelligence, and they have no independent personality, so the heroes of the war group can completely command them, which can also be understood as control.

The generals of the army can completely and subtly command each soldier under their command, and can control them like an arm, and this control is carried out by brainwave ideas, and does not need to be conveyed by the medium of voice and flags. It is both concealed and convenient, and most importantly, it is very timely, and can command soldiers to deal with various emergencies anytime and anywhere.

According to the general situation, a thousand first-level soldiers will definitely not be able to defeat a fifth-level master, if there are three or four thousand first-level ones, they can still exhaust the opponent, but other fifth-level masters can also use guerrilla warfare to grind these small soldiers to death.

And under the complete command of the commander-in-chief, the situation is different. Theoretically, the overall combat effectiveness of a fifth-level master is equal to 10,000 first-level soldiers, but that refers to the comprehensive strength, if you only talk about one aspect, then the gap between each level is just doubled. For example, if you only talk about strength, the strength of a fifth-level master is only twenty times that of a first-level creep.

Then under the command of the commander of the army, twenty first-level soldiers form a military formation, neatly arranged as one person, and when the strength is confrontational, it can completely collide with a fifth-level master. Although in the actual situation, it is impossible to achieve this kind of complete additive effect, but twenty is not enough, thirty or fifty can form a military formation together, then the relative advantage of the master in strength will be gone.

In front of such a team composed of large and small military formations, it became impossible for those masters to grind these soldiers to death little by little through guerrilla warfare. And if they are not careful, they will be surrounded by a coordinated army, and in this kind of military formation, the possibility of the masters escaping is also greatly reduced.

In this way, a fifth-level martial artist was supposed to slaughter a thousand first-level minions, and it could be easily done without the need for guerrilla warfare. But after adding the command of the commander of the army, it became that this fifth-level martial artist had no way to take the same thousand first-level soldiers, and he had to be careful that his own life could be thrown away at any time.

Therefore, in the frontal battlefield, it is very important to have a commander with small soldiers, who can make his small soldiers exert many times the combat effectiveness. Not to mention that these commanders themselves are not given for nothing, they themselves are high-level martial artists who are good at fighting, and then hide in the military formation, the overall combat effectiveness will increase a lot.
