The cold sweat on Chen Long's body came down, what is Du Shao's identity, if he offends him, although it will not be ruined or anything, I am afraid it will not be so comfortable...... After all, there are too many people who want to pat him on the back.

Immediately, Chen Long walked up to Du Shao and bowed frequently, looking sincerely afraid, "Du Shao, I'm sorry, I'm very sorry for this!" ”

Du Shao's hideous face had softened, and he helped Chen Long, who was bent over, up, and said indifferently: "It's okay, it's okay, it's my fault that I'm too obsessed with winning or losing." ”

Du Shao turned his head to Tian Lei again and said, "Xiao Tian, we lost a game, give Chen Shao a thousand yuan." ”

Chen Long was suddenly frightened, and waved his hand again and again, "No, no, Du Shao, it's just entertainment, it's not as good as Caitou." ”

"Hold it for me!" Du Shao glared at him, and said with a majestic face: "I am willing to gamble and lose, it is justified, am I Du Junzhe the kind of person who can't afford to lose?" ”

"......" Chen Long was about to cry, but he had to take the thousand yuan handed over by Tian Shao in the gloating eyes around him.

"I'm a little tired today, come back in two days, Chen Shao, I appreciate your brother very much."

Before leaving, Du Shao patted Chen Long on the shoulder with a smile.

Rumble!

Like five thunderbolts, Long Chen stood there, as if he had fallen into a collapse.

……

Lu Wei returned home.

To be honest, it's not the first time he's encountered this situation, who has played with him, who hasn't had a little money and a bit of power?

But no matter who it is, if you want him to release water, it is impossible, because he doesn't want to play this kind of ball, let him release water, he would rather not play.

Chen Long has also persuaded many times, just to play, the picture is just happy, why make others unhappy? Whether it's benefits or face, if you don't let it, how can others give it?

But it's useless, there's no way, Lu Wei is this kind of temper, no matter which wealthy family or aristocratic son you are, you must be prepared to lose when you play ball with him.

Because, he will definitely give it his all!

……

Tower defense base, main control hall.

Lu Wei carried a hard sofa and appeared in the hall.

"Friend, you're back."

Lu Wei put the sofa in front of the console and sat down comfortably, "Kai, how is the situation at the base, how many energy cores are there now?" ”

"Now there are three."

Lu Wei saw on the monitoring screen that near the energy center, there were three energy cores glowing with blue light, which were rotating around the light axis that had become thicker.

In the center of the optical axis, there is also a crystal nucleus that has formed a small half, which is slowly getting larger...... It's like a hen hatching eggs, and it's very pleasing to watch.

Lu Wei nodded, it took two days to condense the first energy core, and the last two took less than two days, and the condensation speed is getting faster and faster, not bad, not bad.

Kai reported: "A large wave of monsters has gathered at the gate of the base, attacking the gate, and will soon come in. ”

"What monster?"

"There are three kinds of monsters, in addition to yesterday's drones, there are two new monsters today, the swarm and the mobilewalker."

Kai retrieved the data of the two new monsters from the database

[Swarm: Swarms are weak swarm action invaders, and regional weapons are especially effective against them, carrying an energy core]

[Motorwalker: Motorwalker is the basic unit in the intruder team, it has no special power, only loyalty to energy, and motorwalkers can carry an energy core]

Swarms and Powerwalkers are monsters that are a bit more powerful than drones and can cause slightly more trouble for the base.

"There are a lot of monsters in this wave, close to two hundred." After Lu Wei counted the number of monsters at the door, he said with a slight frown.

"Don't worry, the Science Center has successfully developed a flame tower, which will play a role in new challenges."

Lu Wei clicked on the scientific research center and checked the information of the flame tower.

――

【Research Center】

Machine gun tower (buildable)

Flame Tower (buildable)

Laser tower (developed in 28 hours)

――

【Flame Tower】

Construction cost: 150

Description: Its flame cone can cause extensive damage, making it ideal for dealing with swarms of enemies, but less effective against a single invader

――

After reading the information of the Flame Tower, Lu Wei was confident.

The Flame Tower is a tower type based on thermal attack, and is not very lethal to monsters.

However, compared to the machine gun tower, the flame tower has a wide attack range, and the scorching flame cone that spews out can grill a large area of monsters.

Monsters that are attacked by heat also have a characteristic - continuous damage and blood loss, even if they leave the attack range of the tower, the monster may still die halfway due to the burning of the residual heat on the body.

Therefore, using the Flame Tower against a large number of monsters has a very obvious advantage.

Lu Wei looked at the resources in the resource center again.

――

【Resource Center】

Energy cores: 3

Common Resources: 451

Special Resources: 5

Number of Towers: 3/48

――

In the last wave of monster invasion, Lu Wei basically used up the resources of the base, and now more than 30 hours have passed, and the resources accumulated by the resource collector are not much, and only three flame towers can be built.

Moreover, the three machine gun towers that Lu Wei had built occupied the best three positions of the defense platform, and building defense towers in other positions could not achieve the best killing effect.

"Kai, can I tear down the machine gun tower near the entrance to the passage and replace it with a flame tower?"

"It's okay to demolish it, but after demolition, it can only recover 80% of the resources consumed during construction, and I have a better suggestion to transfer this machine gun tower to other towers, so that you don't have to lose unnecessary resources."

"Can the tower still be moved?"

Lu Wei asked in surprise with joy in his eyes.

"Of course, there is a set of mobile devices under the tower system, which can adjust and swap the defense towers on each tower, which is also to save construction time and base resources."

It's a bit like a three-dimensional parking garage, where each parking space can be flexibly adjusted, saving cost and time.

Lu Wei immediately asked Kai to transfer the machine gun tower located at the entrance of the passage to a corner in the middle of the defense platform, and built a flame tower on the vacated tower.

With the remaining 301 resources, Lu Wei built two machine gun towers at a certain corner in the middle of the defense platform.

As for why you don't build one more flame tower, it's because according to Lu Wei's experience, one flame tower is enough to cause continuous damage to monsters, and the stacking effect of building one more is not very obvious.

Dealing with about 200 or so monsters, 1 flame tower, 5 machine gun towers, should be enough!

"Kai, open the gate of the base and face the monster invasion!"

"Okay."

Every time at this moment, Lu Wei was slightly excited, and his blood flow accelerated a lot.

Doodoooo -

Sirens sounded, and the base gates began to open.

Pedal Pedal -

The sound of monster footsteps stomping on the floor came from inside the entrance to the passage.

Lu Wei saw the faces of the monsters.

The colony is much larger than the drone, about two meters tall, with two giant three-clawed feet, a pair of large chelas on the top of the head, and some armor attached to the joints and trunk, but there is still a large amount of connective tissue exposed on the head and waist, indicating that it is not resistant to high temperatures.

The Mobile Walker has a very large head, like a chubby shuttle, and is covered with more armor, making it the most difficult of the three monsters that have invaded the base today.

The monster quickly came within range of the tower.

"Boom~"

The flame tower immediately erupted a reddish flame from a special fuel that was burned with high-purity oxygen at temperatures of up to 1,000 degrees Celsius.

This is lethal to the monster!

The flame-covered monster let out a scream and immediately quickened its march, carrying the remnants of the flames and continuing to run towards the energy center, ignoring the declining vitality.

"Boom Boom~~~"

The flame tower continued to breathe fire, and the most vulnerable drone was burned and fell to the ground after not walking a few steps, and the swarm traveled a little farther, but the machine gun tower made a "click" sound and quickly fell to the ground.

Two motorwalkers, with slightly stronger defenses, arrived at the base's energy core.

Frame!

Frame!

The two Powerwalkers took two Energy Cores.

Lu Wei immediately stood up! Keep their eyes fixed on the two Motorwalkers until they turn back the way they came, and walk in front of the machine gun tower.

Da-da-da-da!

The machine-gun tower did not hesitate to fire.

The metal storm pierced the heads of the two Powerwalkers, causing them fatal damage, and even though they were reluctant to do so, they dropped their energy cores and fell to the ground.

After the energy core fell, it floated under the traction of the core gravity, and slowly returned to the energy center.

Lu Wei breathed a sigh of relief, "It's okay, it's okay, the energy core hasn't been taken away." ”

Two minutes later, all the monsters were destroyed.

Lu Wei nodded with satisfaction.

Lu Wei made a summary of the assessment.

In this round of monster challenges, the performance of the Flame Tower is very good.

At least half of the drones were burned to death by the Flame Tower, and the small half of the swarm also shed most of their blood in front of the Flame Tower, and were finally easily killed by the Machine Gun Tower.

The most threatening of the mobile walkers, the Flame Tower, while not dealing significant damage to them, at least reduced some of the pressure on the Machine Gun Tower.

It can be said that without the Flame Tower, this level would be much more difficult.

A flame tower that wields at least three or more machine gun towers!

……

After the base gate closed, the forklift drove out of the resource center again, clearing the monster corpses from the road.

There is a resource recovery furnace on the resource center, and the forklift collects the monster corpses and bullet casings on the ground, throws them into the recovery furnace, and finally converts them into the resources needed by the base.

"Kai, can you stop the forklift and let me see the corpses of those monsters?" Lu Wei said in his heart.

"Yes, but the oxygen level in the base is much higher than in the main control hall, you need to adjust your breathing."

After the flame tower was studied, Kai produced a large amount of oxygen, and the oxygen concentration of the air inside the base was as high as 34%, which had a certain neuroanesthetic effect on monsters that did not need oxygen to survive.

Opening the door of the main control hall and taking an elevator device to the base defense platform, Lu Wei felt the environment of the base in an all-round way.

The metal floor trembled slightly, and it was the turbine below that was working.

I don't know what kind of metal defense tower it is, it is more than three meters high, the shell is very hard, and the outline light tube of the defense tower emits a faint green light, indicating that this is a primary green tower.

Approaching the energy center, you can not only see three fist-sized energy cores, but also feel the energy fluctuations coming from the core, like a whirlpool, bringing a strong wind to the face.

There were many yellow blood stains on the ground.

Next to the bloodstains, there are monster corpses, Lu Wei squatted down and took a look, kicked a few times, hard, and there were marks left by bullets in some parts, which were very shallow, indicating that these monsters had a very strong defense.

"These monsters are so strong, and they are desperately trying to grab my energy core, which shows that the energy core is more important than their small lives!"

"When the base produces more and more energy cores, according to the commission, I will definitely get one of my own!"

Thinking of this, Lu Wei is not very interested in these broken monster corpses, they can't be eaten, can't be used, and are not easy to sell, so it is better to make more contributions to the base.
