Back at the Tang family, Ye Yifan only stayed for a while and left, at this time, the housekeeper had already transported back a part of the Xingchen Sand and Xingchen Gold, which were relatively close to Tanghe City, and it was easy to do this in the case of dispatching a special flying car.

This batch of Xingchen Sand and Xingchen Gold Ye Yifan has already absorbed them all, and a total of 17 units of Xingmu and 11 units of Xingshi have been added to his castle, and the remaining Xingchensha and Xingchen Gold will be sent to the Tang family early the next morning, Ye Yifan can come and pick them up when the time comes.

As for the funds spent, Ye Yifan had already transferred the 600 million Chinese coins in the card to Tang Boyuan's account before this, and he completely believed that the other party would not do anything, let alone look at his own money, so he was very relieved.

......

"60 units of star wood and 60 units of star stones, you can also build several more buildings now!" He planned based on the total number of minerals he had purchased, which was 60 units of Star Wood and Star Stone, to see how far he could build the castle.

Resource Warehouse: 5 Star Stones, 5000 Crystals - 1 Star Core Crystal per day for the castle.

Blacksmith: 5 Star Wood, 1000 Crystals - War Machines can be purchased.

Archer Tower: 10 Star Stones, 1200 Crystals - Recruits archers.

Level 1 Magic Guild: 5 units of Star Wood, 5 units of Star Stone, 2000 units of Crystal Energy - Allows visiting heroes to learn memory magic, and the Level 1 Magic Guild has 3 levels of Tier 1 magic.

Garrison City (need to build a blacksmith shop, barracks): 10 units of Star Stones, 3000 units of Crystal Energy - can recruit guards, which is an advanced class of infantry.

Base Camp (Stronghold required, town level 9): 5 Star Wood, 5 Star Stone, 5000 Crystals - 50% increased mob production in the town, and obstacle terrain to strengthen the town's defenses (with an arrow tower).

Castle (requires stronghold, base camp, town level 12): 10 Star Wood, 10 Star Stone, 5000 Crystals - Doubles the production of creatures in the town (this effect does not stack with the base camp), and adds two arrow towers (with three arrow towers).

City Council (requires town level 9): 5000 Crystals - Provides 2000 Crystals per day.

Stables (requires town level 9): 10 Star Wood, 5 Star Stones, 2000 Crystals - Increases the movement speed of visiting heroes for the next week.

Equestrian Arena (Stables required, town level 12 required): 15 Star Trees, 10 Star Core Crystals, 6000 Crystals - Knights can be recruited.

Paladin queue (need to build stables, equestrian arena, need town level 12): 20 units of star wood, 15 units of star core crystals, 9000 units of crystal energy - can recruit paladins, as an advanced class of knights.

......

In fact, there are not many buildings in the castle that can be built with only resources such as star wood, star stones, and crystal energy, and many of them are follow-up upgrade buildings, and there are only five buildings that Ye Yifan can directly build at the moment, which are resource warehouses, blacksmith shops, bow towers, first-level magic guilds and fortresses.

"Let's build the bow and arrow tower tonight, uh, no, how come the crystal energy reserve is only about three hundred points, yes, a lot of crystal energy was consumed when delivering internal force to the little phantom leopard today!" When Ye Yifan checked the crystal energy reserve in the castle, he suddenly found that there were only about three hundred points left.

But fortunately, at this time, the daily income of the castle has reached more than 1350 units of crystal energy, of which 1000 units of crystal energy is the income of the castle itself, and the other 250 units are the income provided by the hero who fused with Tang Boyuan's own treasure endless gold cloth bag, and the last more than 100 units of crystal energy is the income of farmers and militiamen, and now Ye Yifan's castle already has 93 farmers or militiamen, of which more than ten militiamen belong to Tang Boyuan, and the hero's special ability "benevolence is invincible" Under the effect, it can condense 2 units of crystal energy every day, and the total amount of crystal energy in the castle can be more than 1350 units per day.

Excluding Ye Yifan's consumption of regular cultivation, he was able to accumulate more than 1,200 units of crystal energy every day.

In this case, Ye Yifan only needs to wait for most of the day to be able to build the bow tower, and it is still in the afternoon, which means that he can accumulate 1,200 units of crystal energy early tomorrow morning to build the bow tower.

"Today is Wednesday, build a bow tower early tomorrow morning, build a blacksmith shop the morning after tomorrow, and build a barracks the day after tomorrow, that is, on Saturday, so that the level of the castle will reach level 9 or above, as long as you accumulate enough 5,000 units of crystal energy, you can build a city council, and then the daily crystal energy income can be increased a lot, just do it, and other things can be slowed down!" Ye Yifan thought about it and finally decided.

According to Ye Yifan's calculations, if it goes well, he will be able to save 5,000 units of crystal energy next Wednesday and start building the City Council, so that from next Thursday, the total income of the castle's crystal energy per day will exceed 2,350 units, and at that time, whether you want to continue to build or quickly riot, you will have an economic foundation.

In fact, the war is still fought economically, Ye Yifan is very clear about this, he knows that when building the Hero Invincible Castle, he must first develop the economy, otherwise he will soon feel constrained and unable to perform.

This is especially true for the Templar's castle, which has the means of training a low-level soldier to become a high-ranking soldier, but it costs three times the price, so the cost of crystal energy will be astronomical.

In addition, there is the Star Core Crystal, which is also one of the most important rare resources of the Templars.

It is precisely because of this that Ye Yifan has even decided to give priority to the construction of the resource warehouse after the construction of the City Council in his castle, so that he can get a unit of star core crystals every day, and slowly save it, and when he builds the equestrian arena and paladin queue in the future, he can directly use it without waiting slowly.
