Although the upgrade of the Ballista Tower has been interrupted, the upgrade of the other buildings is still unaffected, after all, the other buildings are pure newcomer buildings, and only the two most basic materials of wood and stone are enough for the upgrade.

Zhang Qiuhan first asked Xuan Lianhua to upgrade the village chief's office to level 2, which was originally just a slightly larger leaky thatched house, but after the upgrade was completed, it was successfully transformed into a wooden hut, although the roof was still covered with thatch, but it was much stronger than the walls were also thatched.

"System: Your village chief's office has been upgraded, it can store +100 wood, +100 stone, and +100 meters in diameter!"

As the system prompt says, with the upgrade of the village chief's office, the village chief's office has the function of storing materials, so that Zhang Qiuhan does not have to stack all the materials in the open air.

Although stacking in the open air has the same effect as putting it in the village chief's office, and it will not damage the materials themselves, it still has the advantage that the materials stored in the village chief's office will be protected by the system, and even if the village is unfortunately breached, the materials stored in the office will not be looted.

The upgrade of the village chief's office will also be able to expand the area of the village.

Don't think it's useless to expand the area of the village, not to mention that the area will be expanded, so that there will be more space for buildings.

The most important thing is that with the expansion of the village, those resource points that seem to be far away from the village at this time will be absorbed by the village into the scope of the village one after another, and become the direct resources of the village.

Next is the dwelling, after the dwelling is upgraded to level 2, it can increase the population limit, which means that Zhang Qiuhan can finally build a second defense tower.

Although Zhang Qiuhan had a golden and a purple peasant in his hands at this time, it was a pity that these two peasants were used as soldiers, and in the end, Zhang Qiuhan couldn't even build a second defense tower...... Even if it is built, no peasants will be transferred to become militiamen!

Now, with the increase of a population limit, Zhang Qiuhan can finally build a second defense tower.

"Uh...... The question is, what defense tower is the old man building now? Is it possible to build another primitive watchtower? Zhang Qiuhan shook the map, before getting the new high-quality defense tower blueprints, Zhang Qiuhan still decided to keep the empty seat first, anyway, the crossbow arrow tower is definitely enough now.

The last upgrade is the Immortal Altar, but unfortunately the Immortal Altar upgrade cannot increase the number of Heroic Spirits, but can only increase the additional attributes of the summoned Heroic Spirits by 100 points of Qi and blood and 10 points of attack damage.

What made Zhang Qiuhan smile was that when Xuan Lianhua upgraded the Heroic Spirit Altar, the Ingenuity Like Moon skill was successfully launched again, adding an additional attribute of "Heroic Spirit Attack Speed +5%" to the Heroic Spirit.

In this way, this level 2 Immortal Altar is enough to increase 200 points of health, 10 points of attack power, and 5% attack speed to Lanyu, such an attribute, even if it is a level 4 Immortal Altar, don't want to have it, especially this increase of 5% attack speed, this is an extremely rare attribute, even if the Altar of the Heroic Spirit is upgraded to the full level, it is just an increase in health, attack and defense, these things, attack speed or something, don't even think about it!

Xuan Lianhua is really a big baby.

However, the upgrade of the Altar of the Heroic Spirit requires gold coins, and there are a lot of gold coins needed, and it takes 50 gold coins to upgrade, so that Zhang Qiuhan swiped the gold coins that burst out of the stronghold for three hours, and basically smashed them in.

When Xuan Lianhua was busy upgrading the building, Zhang Qiuhan was not idle, and the ten waves of attacks that had accumulated were directly brushed away by Zhang Qiuhan.

The drops are all system-set drops, such as gold, resource points, building blueprints, and primitive towers.

It is worth mentioning, and when the ten waves are finished, the new wave, that is, the 30th wave, has just been refreshed, and Zhang Qiuhan also clicked it off for him.

It's just that as the 30th wave of Yuan Kou was easily killed by the Repeater Arrow Tower, a letter wrapped in an envelope fell out of the last Yuan Kou's body.

"Why doesn't the old man remember that there is such a thing as a letter in this fixed drop?" Seeing this falling envelope, Zhang Qiuhan was stunned for a moment.

"Wait...... The old man remembers that this 30th wave seems to be the first wave of real random drops, not the Yuan Kou that the system has fixed drops! Zhang Qiuhan's eyes lit up instantly.

As mentioned before, the items dropped in the first 100 waves of the game are basically dropped items set by the game company, because if these items are not handed over to the player, the player will not be able to play the game normally.

For example, if you don't drop a few blueprints of the original tower in the early stage, then the player won't even be able to build a second primordial tower, and they won't want to survive the first ten waves of attacks for the rest of their lives.

There are also blueprints for various buildings, Heroic Cards, and the like, as well as key building resources.

Anyway, these are all pre-set props that can fully satisfy players through the early 100 waves of attacks, and fully allow players to experience the thrill of the early game.

And after 100 waves, the player is already level 5, and the heroic spirits in the hands of players can also go to brush some low-level strongholds to explode equipment, and the floating fortress Ark of Tomorrow, which flies high in the air, is also officially open to newcomers, if the luck is too bad to hit the required drawings and equipment, then you can also go directly to the Ark of Tomorrow to trade with other players to obtain.

Anyway, after level 5, players are basically completely free from the system's arrangement and can play the game freely.

However, this does not mean that all the items dropped in the first 100 waves are fixed, and there are still a few waves of Yuan Kou whose items are random, and the first wave of Yuan Kou that really drops randomly is the 30th wave of Yuan Kou.

But this dropped an envelope at random, what is it?

Zhang Qiuhan picked up the envelope with curiosity.

opened it directly, and the two big characters on the front of the envelope made Zhang Qiuhan understand what kind of gift the system gave him.

These two large characters are written "War Books".

Yes, that's right, the 30th wave of Yuankou randomly dropped a battle letter to Zhang Qiuhan.

Afternoon!

This is probably the most anticipated and feared drop item in "Tomorrowland".

The purpose of the war book is obvious, it is a document to declare war on you.

It's just that this war book doesn't come from the players, but from the primitives.

Tomorrow there will be some powerful Yuankou in the continent, these Yuankou do not belong to the fixed refresh attack Yuankou, they will randomly pick the village they don't like, and then send a war letter like this village, telling this village that they are about to launch an attack on this village!

To put it simply, a boss has taken a fancy to your village and wants to have a boss attack village battle. Such a battle is an attack that is calculated separately from the normal refresh.

And such a boss is called the battle book boss.

The Battle Book Boss is an existence that surprises and delights players.

Happily, since it is a boss, it will definitely drop all kinds of valuable and rare props, and at least some merit points will be dropped, which can be exchanged for various rare props in the merit shop.

Anyway, as long as you can kill the Battle Book BOSS, the benefits and rewards are great, and they are worth the gains of more than ten days of hard work for players.

But the disadvantage is that first of all, the Battle Book Boss cannot be refused, and the War Book Boss will definitely launch an attack on your city at some point in time within 24 hours, and the player has no refusal, or even the right to choose the battle time.

The strength of the battle book BOSS is based on the current level of the player's village to float, if you add the current level 10 of Zhang Qiuhan's village, then the person who issued the battle book may be a level 5 BOSS, so it will be easy and happy, a piece of cake.

But if the level is higher than Zhang Qiuhan's village...... It doesn't need to be too high, as long as it is 1 level higher, the player's existence will probably not be able to hold on, because the strength of the Battle Book BOSS is far stronger than the normal attacking Yuankou.

And in case you brush up to the top grid configuration, that is, the 15-level battle book boss that can be higher than level 5 comes out, then there is no need to say anything, the village can be demolished, and the resources that can be transferred will be transferred as soon as possible, so as not to get the village to be breached, and the losses will be too heavy.

Seeing the boss of the battle book, Zhang Qiuhan couldn't help but wonder whether he was an African or a European.

This war book boss is generally only refreshed after level 100, but as a result, Zhang Qiuhan's old man in the 30th wave, the first random drop brushed out the war book boss, and no one has this luck!
