Tower defense base.

Lu Wei, who had just taken a shower, comfortably brewed a cup of strong coffee, sat comfortably on the office chair, and started his daily base management work.

On the crystal screen, tap on the Resource Center and the Research Center.

After the development of the last few days, the base has entered a stage of formalized operation.

The number of energy cores has increased to more than 700, and all the towers on the defensive platform have been built, and the new tower array is 1 second-level flame tower, 10 second-level machine gun towers, 19 second-level cannon turrets, 6 second-level laser towers, 2 second-level control towers, and 10 long-range artillery towers...... The tower array is very powerful.

I have to mention the long-range artillery tower of the scientific research center, after the development of this kind of tower, when attacking monsters, it will throw a high-heat fireball with a diameter of one meter into the air, the temperature of the fireball is as high as 1,000 degrees Celsius, and it can fall into the monster group, not only can it produce a certain amount of "impact" damage, but the high-heat fireball will also explode, forming a wider range of splash damage to the surrounding monsters, and the power is extremely powerful.

The long-range artillery tower belongs to a super defense tower with thermal energy + kinetic energy + ultra-long range + wide area killing, but the disadvantage is the same as the cannon turret, the rate of fire is very slow, it cannot hit targets at close range, it is very wasteful to strike a single target, and it cannot attack high-speed and stealth targets.

In order to improve the efficiency of the tower array, Lu Wei built two control towers and upgraded them to the second level, ensuring that after the invisible monsters entered the base, they could not hide on 40% of the road section.

After a few more days of adjustment, the power of the tower array has almost reached the most ideal state, so in the past five days, the base has not lost a single energy core.

Although the energy core has not been lost, the threat of monsters is increasing every day, such as the flying monster, a new variety has appeared that has never been recorded in Kai's database, flying fast and shaped like an eagle, which Lu Wei named "Eagle"

The speed of the eagle is very fast, and as soon as the vent is opened, it is like a bolt of lightning, rushing towards the energy center at a speed of more than 80 kilometers per hour, bringing a gust of wind, and running when it gets the energy core.

Fortunately, several eagles were wiped out, but if the number of eagles exceeded ten, I am afraid that the result of the loss of energy cores could not be avoided, so Lu Wei asked Kai to prepare to develop the missile tower with the best air defense effect to deal with the air threat.

"Wei, today's situation is a little bad, there is a strongest monster recorded in the database at the gate of the base - the world master, we have to cheer up, it is a very difficult character to deal with."

"World Domination?" Lu Wei was surprised, "How strong is the World Master?" ”

"Very strong! In my memory bank, the World Juggernaut has taken the most energy cores. ”

Kai brought up the information of the World Master.

[World Juggernaut: The World Juggernaut is the most powerful boss of all monsters, it has a heavy protective shield, as well as large armor, the protective shield can eliminate the damage received from the front, and it is also effective against heat-based continuous attacks, its only weakness is that it is relatively slow. The World Juggernaut can carry three energy cores]

Through the monitoring of Lu Wei, he saw that the appearance of the world master was very similar to that of the uninvited guest, but the body was bigger and stronger! There was also a transparent protective shield on the outside of the body, and the entire base could be felt as the two thick claws on the shoulders slammed into the metal gate.

"Wei, the base gate has been damaged by 87%, and the gate will be damaged in fifteen minutes, you have to make a decision as soon as possible!"

Kai is a little anxious, once the base gate is damaged, it will take a certain amount of time to repair. If the gate is left open for a long time, the monster will drive straight in, and the defense tower system will have to be kept open at all times, which will take up a lot of electricity and brain computing power, which will affect the production speed of energy cores...... This is also the reason why the base has to open the gate regularly to let the monsters in.

"Kai, don't wait, let the monster in."

Lu Wei did not adjust the tower array, the current tower array is already a relatively ideal tower array that can be combined, and it is unlikely that the attack power will be increased until the new defense tower is developed by the scientific research center.

The alarm sounds, and a large wave of monsters enters the base!

……

Twenty-five minutes later, the base gates closed.

The loss of 6 energy cores is a huge loss.

Today's situation was a bit unexpected by Lu Wei, the number of flying monsters was nearly double that of yesterday, especially the eagle with the greatest threat, ten of them came at a time, six of them were killed, and the remaining four eagles took three energy cores.

As the strongest boss of the world, it is not in vain, Lu Wei asked Kai to concentrate almost all the cannon turrets and long-range turrets to attack, firing nearly a thousand shells and high-heat fireballs, but the result was still helpless against the protective shield of the world master, watching the world master take away the three energy cores.

"Why is the shield of the World Ruler so thick? Such a powerful firepower doesn't die, and this doesn't make people play? ”

Lu Wei felt a sense of powerlessness in his heart, it was too strong, the world master was too strong, but any attack hitting its protective shield was like tofu hitting a steel bowl, it had no effect, he could only watch it wander around in the artillery fire, as if he was taking his own things, and took away 3 energy cores.

"It's not your fault." Kai explained, "The power of the defense tower is still too small, and only the red tower in the third state can penetrate the protective shield of the world master relatively easily...... But it will take a while, and after a week, the research center will be able to study the first type of red tower......"

There was a trace of worry on Kai's face: "However, after the monster gets the energy core, after a period of digestion, the armor is thicker, and the formation of protective shields is more difficult to deal with, even to the extent that the third-level cannon is helpless, and at this time, we need a new kind of defense tower, specifically to deal with protective shields." ”

"Tesla Magnetic Storm Tower?" Lu Wei immediately thought of this kind of defense tower.

"Yes, but I don't have the name Tesla in my database, I'll call it the Magnetic Storm Tower, the Magnetic Storm Tower is the ultimate defense tower against monster shields, and its super current can eliminate the effectiveness of any protective shield."

"After the development of the missile tower is completed, can the development of the magnetic storm tower be carried out immediately?"

"Yes, the technical content of the magnetic storm tower is relatively high, so the development sequence is relatively late, and the time taken is relatively long."

Lu Wei nodded, he knew that the more advanced the defense tower, the higher the technical content, the more late it was, but the effect was huge!

There are a total of ten types of defense towers that can be developed in the research center, and with the missile towers that are about to be developed, eight have been unlocked so far.

The remaining two are the Magnetic Storm Tower and the Space-Time Tower.

Thinking of the space-time tower with a slowing effect, Lu Wei couldn't help but ask: "Kai, after the successful research of the magnetic storm tower, can the space-time tower be developed immediately?" ”

In recent days, the number of monsters who have come to the valley where the tower defense base is located from all directions has reached a peak, and there are about two thousand monsters wandering outside the base gate every day, especially high-speed monsters and invisible monsters such as sprinters and lurkers, who can often touch the energy core and have the danger of snatching the energy core.

Laser towers are a powerful weapon against such monsters, but there are only six laser towers in total, and there is no way to eliminate all high-speed monsters and invisible monsters, and the possibility of slipping through the net is increasing.

There are also bosses such as the more threatening Elite Monster and the World Master, which are increasing in number and quality, and the tower array of 46 offensive defense towers after removing the two control towers is becoming more and more difficult to deal with.

Therefore, Lu Wei urgently needs a space-time tower that can slow down monsters, and it will be developed by the scientific research center as soon as possible.

"I'm afraid this won't work, the space-time tower involves certain laws of time and space, and the scientific research center can't grasp the space-time technology thoroughly."

"However, 10,000 years ago, the base started research on the space-time tower, but the research and development progress was less than one-third, and the base stopped operating, but the data is still there, and after the scientific research center is upgraded, the development of the space-time tower can be restarted." Kay explained.

"Upgrading the research center? How do I upgrade? Lu Wei asked.

"When the base is upgraded, the scientific research center is also upgraded."

"How can the base be upgraded?"

"When the reserve of ordinary resources in the base resource center reaches 1 million units and the special resources reach 200,000 units, the base can start the upgrade process and upgrade from a primary base to a second-level base."

Lu Wei was taken aback, "It takes so many resources to upgrade the base?" ”

Hearing the two numbers of one million and two hundred thousand, Lu Wei was stunned, the current ordinary resources that the base can collect in a day are about 4,000 units, and the special resources are 800-1,000 units, to reach one million and two hundred thousand respectively, when will this have to wait?

Kai knew that Lu Wei was anxious, so he comforted: "Don't worry, Wei, in about half a month, I will give priority to upgrading the resource collector of the base, and the speed of collecting resources from the ground will increase by more than five times, and the special resources will also increase with the increase in the number of monsters." ”

Lu Wei nodded, with the recovery and development of the base, the threat posed by the monster is getting bigger and bigger, once the development can't keep up with the pace, it may come to a standstill, and the loss of 6 energy cores today is not a problem with his tower array combination, but the protection of the super monster exceeds the upper limit of the defense tower's attack, and it can't even break the defense, how can it be killed?

A powerful world master has appeared, will there be more powerful monsters in the later stage? It's unpredictable, after getting the energy core, the monster's ability will be greatly improved, and there may even be a batch of super bosses that are many times more powerful than the boss, such as the snail...... In the future, it may become a stumbling block to the development of the base.

The burden on my shoulders is really heavy.

But no matter what, the development of the base must run ahead of the monsters!

"Kai, after the development of the missile tower is completed, the research and development of the magnetic storm tower will be started immediately!"

After a warning, Lu Wei, who was already very tired, returned to his bedroom.
