Zheng Feng himself is upgraded according to his level, which means that if he is promoted to three levels, his subordinates will be promoted to one level. However, for example, these two classes are non-combat types, and they cannot be upgraded.

In addition to the barracks and the Hall of Heroes, there are also units in the Commander's Mansion that can be produced, and according to Gu Gu, what is produced here are Zheng Feng's exclusive supplies and characters as the master. The first level of exclusive supplies is a mount, but the price of this mount is too high, it costs one million tons of grain, 500,000 tons of metal, and 50,000 grams of rare minerals, and Zheng Feng doesn't have these resources to make it now.

In comparison, the two groups of heroes in the first level are cheaper. The first-level heroes of the battle group are from the Black Butler, Sebastian and Claude, who both ask for 50,000 tons of food, 50,000 tons of metal, and 10,000 taels of gold. The first-level heroes of the war group come from the Zongheng family among the hundred princes, that is, Su Qin and Zhang Yi, the two guys who eat by mouth, and both of them want a price of 20,000 taels of gold.

Probably because this is the first level of the reason, these two groups of heroes are quite special. Although those two demon stewards are also quite powerful, they are basically relative to humans, and their combat power should be some distance from other heroes, which can be seen from the fact that their value is not as high as Zheng Feng's mount.

However, at the first level, there was not even a single soldier, and it was obvious that it was not the time to fight, so these two all-round demon butlers were more suitable for the current needs, at least their cooking skills were much stronger than Zheng Feng's.

For the same reason, those two Zongheng families did not come out to lead troops to fight, and it is understandable that they were created as lobbyists before other generals. Moreover, the really important combat effectiveness and the generals who lead the troops can't be created now, and they should at least be about the same price as Zheng Feng's mount.

After reading it again, the only instruction that Zheng Feng can issue now is to study technology, fishing technology requires 1,000 taels of gold, and farming technology requires 10,000 taels of gold. As for the simple work of logging and mining, there is no need to study it here.

Fishing is easy to say, but it's not easy to do, first of all, you have to be able to find out where the fish are, you have to have fishing nets, and you have to have many people to spread and pull the nets, as long as this money is very cheap to study. As for farming, it is more complicated, it is necessary to plough the ground, sow seeds, weed, water, kill insects, etc., and the cultivation in this era is manual, and there are no machinery, and farming is really a technical job.

The technology in the system,It's over after research.,There's nothing like an upgrade in the back.,It's not a game.,There's no sense of step-by-step.,It's directly the highest technology that conforms to the rules of this world and the status quo of the times.。

After issuing this order, Zheng Feng had nothing to do, so he went downstairs to see the work of those people and waiters, although these robots-like troops are not lazy, but Zheng Feng has not seen them work, it is still a little fresh.

When they came downstairs, there were already hundreds of people in those people, and they were carrying trees one by one, as well as carts of stones to and from a warehouse not too far from the commander's mansion.

This warehouse is about a few hundred meters away from the Commander's Palace, it was summoned by the waiter, and it is also a key building, its role is to transform resources, as long as the people send the collected trees and stones into these warehouses, the system will convert those things into various resources.

Many warehouses could be built, each of which required thirty tons of wood and fifty tons of stone, and a hundred taels of gold. These warehouses are only about fifty square meters, which is not very big, but those things will be transformed as soon as they are put in, so they don't need much space.

Zheng Feng walked into the warehouse and watched as the stones gradually blurred, and then disappeared like this. After looking at it for a while, he couldn't see anything, Zheng Feng pretended to sigh for a while and walked out of the warehouse.

Coming to the back of the Commander's Palace, there are also buildings being built here, which is the fifth type of building housing that can be built at the first level. Housing is for those who have been produced out of the army to live and rest, the first level of housing is a dwelling, only 25 tons of wood and 50 tons of stone can be, these first level of dwellings only have one floor, about 50 square meters, each dwelling can accommodate eight people.

According to the production rate of the barracks, excluding a part of the rest time, it can produce a thousand people per day, that is, one hundred and twenty-five houses. And a waiter can only summon ten dwellings a day, so Zheng Feng asked the system to produce twenty waiters.

Walking into these houses, the layout is very simple, divided into five rooms, four are for residents, and one is a tool room. In a room for every two people, there were only two small cabinets, and in the tool room were the tools that were not used for the time being, some were pickaxes and hammers, some were axes and long saws, and every dwelling had sickles and sacks.

After a long walk between these houses, Zheng Feng returned to the Commander's Mansion, because after a day's time, the first hero, Sebastian, had already come out. The image of this demon butler is similar to that in the anime, with a well-fitting tuxedo, elegant gentlemanly manners, and a kind smile on his face.

After a circle around the butler, Zheng Feng gave him a serious order with his hands behind his back, "Well, Sebastian, let's go make dinner now." "Yes, master. The demon butler simply bowed slightly to Zheng Feng, and walked elegantly to the kitchen on the second floor.

Well, it seems that this hero is still a little different from the original book, at least this demon butler can't speak English, and it seems to be more crisp than the style in the anime. After all, this is a new life form created by the system according to the rules of this world, they are brand new life, although the image and ability are based on the original image in the notebook, but the real life form and video data will naturally have some differences.

Sebastian's work efficiency is very high, and it didn't take long for dinner to be ready, although it was all some melons, fruits and fungi food, but the taste was still quite delicious, and it was definitely the chef's skill in the big hotel. In fact, at noon, Zheng Feng also thought about making some fungi to taste, but he was afraid of eating poisonous mushrooms, so he only made bird eggs, and the other ingredients were not moved.

After eating the Demon Butler's craft, Zheng Feng no longer plans to cook by himself in the future, but he doesn't need Sebastian to do other things for him. For example, changing clothes and bathing, Zheng Feng didn't want a man to watch from the side. Zheng Feng is not the little Charles of the Van Dom Hewe family, and he doesn't have the strange habit of letting men serve him. So on this day, Sebastian was resting in the living room, and he was also a housekeeper, so he couldn't let him go to live in the people's cabin.

On the morning of the next day, after eating the breakfast prepared by the demon butler, Zheng Feng went with him to the gate of the Hall of Heroes and waited for another demon butler to come out. After a night, the Claude Faust of the Torrenci house was almost finished.

After a burst of inconspicuous strange light flashed, out of the door of the black hole of the Hall of Heroes came out of a demon butler, his image is very similar to the previous Sebastian, even the appearance is a little similar, probably an elegant gentleman and handsome guy, after all, these two people are close to perfect faces, and some similarity is normal.

After Claude also saluted Zheng Feng, Zheng Feng took the two demon butlers to a bare stone mountain, where he asked the two heroes to make a move to see what the fight was like in this world.

Sebastian and Claude first saluted each other gently, a few dozen meters apart, and then crackled. But it's a pity that Zheng Feng's level is still too low, he only has a first-level physique, and he can't see the movements of these two guys clearly at all, he can only see a black shadow floating around on the stone mountain, and a few swishing sounds come from time to time in his ears.

This kind of battle scene is really not interesting, Zheng Feng only looked at this kind of battle scene that he had never seen before with excitement at the beginning. But after a long time, it was no longer interesting for him to see anything clearly, so after the two demon butlers fought for a while, Zheng Feng told them to stop.

The manufacturing cost of these two guys is the same, which means that their comprehensive ability is comparable, and they are the same type of heroes, and even the advantages and disadvantages are similar.

Therefore, Zheng Feng called them over for some tests, such as strength and speed, as well as attack power or something. At least Zheng Feng can understand this kind of test, and he doesn't have to look at the black shadow that he can't see clearly. The way of testing is very simple, the strength is based on the weightlifting, the speed is a sprint to see, as for the attack power, there are big rocks everywhere, just hit a few times.

The results of the test Sebastian were two hundred and forty meters per second and was able to lift a weight of 2.8 tons. Claude is two hundred and twenty meters per second and is capable of lifting a weight of three .2 tons. Obviously, Sebastian was a little faster, and Claude was a little more powerful than him, and the two men were still half a pound or two.
