Coming to the north of Tianhua Kingdom, Wang Haoyu was most worried about safety. It is still very dangerous for such a big target as the base to pass through the www.biquge.info here.

Only by strengthening the base to the point that others dare not provoke Wang Haoyu can gain a foothold in this last world. And all of this is about money.

Whether it's self-enhancement or the construction of the base, everything requires a lot of magic crystals. Without magic crystals, it's all empty talk.

After coming to the north, Wang Haoyu knew that the strength here was strong. But he was not afraid of this, the more he was like this, the more he was able to provoke Wang Haoyu's pursuit of power. Only when you land on the starting line can you have the motivation to catch up desperately.

After getting these 20 million magic crystals, the first thing Wang Haoyu did when he returned to the base was to upgrade his weapons.

After a burst of light, everyone in the base was stunned. At the same time, those defensive weapons inside the base began to change.

First of all, the outermost city wall, which was tripled from 400 machine guns at once. Not only the quantity, but also through the three-dimensional image, Wang Haoyu saw that their shape was also much larger than before. At first glance, the power is much stronger.

By seeing the prompts of the system, Wang Haoyu knew that those machine guns could be charged with 5,000 rounds of ammunition every day. As a result, Wang Haoyu's base can fire a terrifying 6 million rounds of bullets every day.

What kind of concept is this, Wang Haoyu can't imagine. If he returned to the middle of the Tianhua Kingdom, he believed that with these machines alone, it was very likely that he would be able to wipe out a large-scale beast tide.

And in the inner wall, 500 small cannons appeared. The power of this small cannon Wang Haoyu has tested, and it can easily kill level 2 zombies and mutant beasts, even if it is level 3, it can also hurt it.

Each of these 500 cannons can be charged with 500 rounds per day, which is more than 20,000 rounds of shells.

Although there are not many of them, they are cannonballs and not bullets after all, and the power has naturally increased a lot.

In addition to small cannons, there are also array-type dense artillery systems, but they are not as many as Wang Haoyu imagined, only 30 sets. But each of them can be charged 100 times a day, so in just one day, Wang Haoyu can carry out 3,000 rounds of carpet bombing on the target.

Wang Haoyu remembered that at the earliest, when he encountered the life-taking level 3 enhancer sent by the Aolong base, he injured the opponent in just one round of intensive bombardment, which showed its power.

This dense artillery system is mainly aimed at the beast tide, and the starting point is not high, but the area of attack is large. Whether it's against the beast tide, or against other bases. With this weapon, it is definitely a big killer.

Twenty missile systems are erected on top of those dormitory buildings in the military zone. To Wang Haoyu's disappointment, they only increased in number, but their daily charge remained unchanged.

Each missile system is capable of firing one heavy missile and 10 small missiles per day. But fortunately, the overall number has increased, which can be regarded as an improvement.

And on the four small buildings next to the main building, there are four iron towers. Now Wang Haoyu saw the prompts on the system and finally knew their names - Light Prism Tower.

Wang Haoyu felt that he had heard this name somewhere, but after thinking about it for a long time, he still didn't remember it, so he gave up.

But Wang Haoyu didn't doubt the attack power of these prismatic towers at all, through previous experiments, Wang Haoyu knew that they were effective against level 5 zombies and mutant beasts. It's still surprising to be able to kill zombies and mutant beasts of that strength.

It's just that the number of times they charge each day is too small, and after upgrading, each Prism Tower can only be charged 5 times a day. That is, four towers can only attack twenty times a day.

Fortunately, the power of the Prism Tower is there, although the number of times is less, but the power is still considerable.

And above Wang Haoyu's main building, a new weapon has appeared. That's something like a radar in the real world. Out of an iron pot was a stick with a small ball on top of it. The whole weapon looks very shabby, and you can't even tell that it's a weapon.

As with the previous upgrade from level 5 to level 6, the current weapon system at level 7 still has no description of this weapon.

But despite this, Wang Haoyu will not despise this weapon. Since the establishment of this system, it must have gradually improved with each level, and the weapon system has become more powerful.

The overall upgraded weapon system may not seem like much, but the actual value is not trivial. Wang Haoyu roughly calculated the value of these weapons, and couldn't help but be secretly shocked in his heart.

Take 6 million magic bullets as an example, to be able to achieve such power, it takes 1 magic crystal to say the least. In this way, it is 6 million.

And the small cannon and the cannon are worth millions. And those weapons in the back, because of their powerful power, their value cannot be calculated with magic crystals.

But that's all, the charging value of Wang Haoyu's base has reached tens of millions every day. With ammunition of this value, I am afraid that even a large base cannot afford it.

This is the benefit of Wang Haoyu having a system, he only needs a one-time investment, and he can get a steady stream of returns. Not only can weapon systems be recharged on a daily basis, but other industries similar to farming and breeding are constantly growing and reproducing on a weekly or monthly basis.

Although there are a lot of energy points required to level up, the benefits that come with each upgrade are enormous.

When the weapon system was upgraded, those people in Wang Haoyu's base woke up one after another. But fortunately, this upgrade is only a weapon upgrade, and there is no change in the pattern, so the impact is a little smaller.

This is also a disadvantage of the system, after the base is occupied, the upgrade can only be done in the original base. Fortunately, the system has the function of stuning all the people in the base, but despite this, it is still a big drawback.

However, these drawbacks can be ignored compared to the benefits of system upgrades.

After the upgrade, Wang Haoyu's base strength has been greatly improved. In the midst of these last days, there is some power for self-preservation.

Early the next morning, Wang Haoyu exchanged several buses from the system. Since there is no such vehicle that can store live fish, Wang Haoyu has no choice but this method.

Fortunately, the fish that passed through the fish pond of the base were alive and could not die within an hour. After his subordinates loaded 10,000 fish into the car, Wang Haoyu left the base with his dragon group guard leader and drove towards Starry Sky City.
