Thinking of this, Ye Bing really had the urge to save energy to upgrade the mechanical barracks!

However, the thought of the huge amount of energy expenditure that awaited him in front of him, and the goal he had been planning for a long time, finally had to calm down and suppress this idea for the time being.

Sighing, he just chose to produce a recycling cart in the end, spending 10 points of energy.

After doing this, Ye Bing still had a dozen points of energy left in his hand.

He didn't rush to spend this energy immediately, but silently counted the resources at hand.

In terms of the resources that can be taken away, Ye Bing now has:

4 reconnaissance robots;

1 military soldier;

2 Spartoons;

1 machine-mounted sapper;

7 assault rifles.

The above are the combat resources that Ye Bing can bring out.

He thought about it, and reluctantly found that these words alone to achieve his goal seemed to be far from enough.

At least, if you want to deal with hundreds of zombies, there are a few more ranged soldiers, and the lethality must be a little stronger, and you can't just rely on the strong pressure of the air cannon to shock the enemy. Melee soldiers also have to play a role, and it's not okay to wilt after just three minutes of being erected.

If you want to change these two things, you'll have to look for a way in the tech tree.

Ye Bing jumped to the technology tree menu, found the mechanical barracks, and soon saw a series of troop names.

He clicked into the Splatoon column first, and soon a series of technologies about the Splatoon popped up:

"The name of the technology: silencer. Level: Ununlocked. Effect: When unlocked, a silencer will be introduced to the Sparter's weapon, reducing the noise emitted by the weapon to a certain extent without reducing its power. The effect of noise reduction will be enhanced as the technology level increases. ”

"Tech name: Air Cannon. Grade: LV1. Effect: This technology is the Sprayman's own technology, which can compress the air to the air cannon**, causing weak damage to the enemy directly in front of it, and at the same time producing a knock-out effect. Its damage and knockback effects increase with the level of technology. ”

"The name of the technology: flamethrower. Level: Ununlocked. Effect: When unlocked, the Sprayer will increase the flamethrower function, dealing fire damage over time to enemies within a certain radius. Activating this feature requires the consumption of Magic Shard Energy, and the burn radius and flame strength will increase with the technology level. ”

"Technology Name: Ranged Weapon Mastery. Level: Ununlocked. Effect: When unlocked, the Squirter will be able to use other simple ranged weapons. As the level of this technology increases, the Sprayer's skill and breadth of ranged weapons will be further enhanced. ”

After reading these briefly, Ye Bing felt more and more that the construction of basic buildings such as the mechanical barracks was just the beginning, and if you want to make the troops stronger, the enhanced technology in the technology tree is an essential thing!

Just take out these four technologies casually, none of them are given for nothing!

First of all, the silencer. Needless to say, this thing is useful, and in order for the Sprayers to be useful outside of the base, it almost has to be upgraded, otherwise it will attract hordes of zombies as soon as they fire.

Secondly, air cannons. Ye Bing also felt that this thing was useless at first, but as his understanding of the class deepened, he felt more and more that this was a magic skill, at least at this stage. The reason is very simple, because it is currently the only one that can achieve the effect of "controlling the field"!

In the event of a companion attack, or a large number of zombies surrounding, a few Sprayers upgraded with high-level air cannons will be invaluable in buying the team valuable time by knocking out the zombie hordes.

Again, flamethrowers. For now, this is definitely the most powerful group attack weapon Ye Bing has encountered! Now that the beam tower and other defensive buildings cannot be transferred, if there are a few more sparzzers who master the flamethrower, it is estimated that even if you encounter hundreds of zombies, you will not be afraid!

The only headache is that this function is the same as the combat state of the martial soldiers, and it needs magic crystals to activate, and if you don't calculate it carefully, it will be a big expense.

And the last, ranged weapon mastery. Although the system does not explain much, it is clear that it is useful. According to Ye Bing, this technology may be one of the most practical and useful technologies in the future. The reason is simple, if the Spray can master long-range weapons, the assault rifle is certainly within range!

At least until the birth of second-order zombies, the killing effect of assault rifles on zombies was still quite large. Not to mention anything else, as long as you can form a team of hundreds of assault rifle jets, it is estimated that the entire city can go sideways!

But it's still the same old saying, dreams are very full, but reality is very skinny. By that time, it is unlikely that there will be no month!

After thinking about it repeatedly, Ye Bing finally only unlocked two of them - the silencer and the long-range weapon mastery, and upgraded the air cannon to LV2, which cost a total of 11 energy! (The first two costs 3 energy to unlock, and the latter costs 5 energy to upgrade.) ）

Although the flamethrower is very powerful, there is really no extra energy to use for it at the moment, and it can't be used even if it is unlocked, so it can only be thrown down temporarily.

Then, in the interface of the martial soldiers, Ye Bing also found a lot of good technologies, but due to the limitation of the energy at hand, he only upgraded one existing technology in the end - the combat form. After upgrading to LV2, the characteristics of the combat form have been changed as follows:

"The duration of each battle form has been increased from 3 minutes to 10 minutes; The combat form can be interrupted, and the energy will be retained; Action speed increased from 2x to 2.5x. ”

It can be said that this upgrade not only enhances the power of the soldiers, but also makes a leap forward in their endurance. Now, they can finally make a real difference on the battlefield.

After getting these things, the energy in Ye Bing's hand was used up again, which made him feel extremely helpless. At the same time, due to the upgrading of buildings, the manufacture of recycling vehicles, and the unlocking of technology upgrades, the base points have increased from the original 30 points to 41 points, and the growth rate of points is also similar to the speed of energy consumption. The handling limit has been increased from 10 to 12, which doesn't make a difference.

That night, because there was nothing to do, Ye Bing went to bed early after a few hours of freehand exercise. While he was sleeping, the affairs of the base were still running, including the construction of underground passages and the removal of zombies.

After a good night's sleep.

The next day, when he woke up, he not only found that the energy of the base had increased again, but also received a prompt from the big screen:

"Your terrain removal is complete!"
