After thinking about it, He Zhiyuan commanded his brain and established the third scientific and technological building, the mechanical fire depot, in the revenge hive base.

With a roar, a huge fungus blanket spread out from under the base's command tower, and immediately, a huge piece of flesh quickly appeared on the fungus blanket, squirming incessantly. In about two days, the command brain of the mechanical fire depot will appear, and it will be fully metalized to form a defensive shell, completing the entire construction process.

This tech building is the Hive Base's Weapon Evolution Arsenal, which allows the entire base to produce more advanced static defensive weapons, and also allows He Zhiyuan to provide more sophisticated individual weapons. With this thing, He Zhiyuan's revenge hive base can gradually become a real fortress.

The fortress of the base is one of the priorities of He Zhiyuan's work in the next few days, but this is definitely not an overnight process. The weapon system and static defense system of the Zaka Zerg must be continuously upgraded, from the simplest guns and the simplest defense system, all the way to the top weapons and systems, this transformation must be completed step by step, and the level of the mechanical fire tank directly determines the level that the weapons and defense system of this base can achieve. Therefore, in the case that the mechanical firepower depot has not yet been completed, what He Zhiyuan can do at present is only to build a rough defensive framework first.

Regarding the defense system of the revenge hive base, on the way back to the base, He Zhiyuan had thought about it many times, and he also had a rough draft in his heart.

At this moment, He Zhiyuan seems to have a lot of raw materials and energy, but for the construction of the entire base. It's still overstretched. In the case of limited energy and tight time, the defense plan designed by He Zhiyuan can only be practical and economical.

In He Zhiyuan's design plan, the defense of the front line of the base is the top priority, in any case, "keeping the enemy out of the country" is always the best situation for defense, once the enemy enters the interior of this revenge hive base, it will always cause damage to the facilities in the base, and it is his He Zhiyuan's things that are damaged.

On the forward positions of the Vengeance Hive base. The scheme designed by He Zhiyuan is a common "open one-side" formation in the land base of the Zaka Zerg.

The so-called "net open side" formation. It refers to covering most of the surface area of the entire base with the energy protection aperture and the two-headed snake static defense system, so that most of the surface area of the base becomes an impassable area - before the energy of the base is exhausted, the energy protection ring is an unsolvable defense. Even if the enemy tries to use some special means - such as He Zhiyuan's means of transmitting the bright moon - forcibly or by tricks to break through the energy protection circle. But the two-headed serpent's static defense system immediately behind the energy protection ring. But it can leave the invading enemy dead without a place to bury. Such a stubborn and ferocious defense will discourage most of the enemy from storming this defensive circle.

And the relatively narrow area at the gate of the Vengeance Hive Base is the only "hole" in the entire defensive aperture. This is a place that the energy protection ring and the two-headed serpent's static defense system can't take care of. But here all the defensive firepower in the forward positions will be concentrated.

This is the "open side" defensive position that the Zaka Zerg like to use - using a powerful and even somewhat scoundrel defensive aperture to force the enemy to charge and attack only the only "hole", and at that only "hole", all defensive firepower is concentrated. This not only makes the base's defensive firepower quite ferocious, but also very energy-efficient.

And at the only "loophole", He Zhiyuan arranged three layers of firepower: the first layer is dominated by all kinds of standard missiles of the Zaka Zerg, which have an extremely long range and the most ferocious firepower, which can start to cause effective damage to the enemy from a very long distance.

The second layer, dominated by various beam weapons and Rayser firearms, this layer has the most dense and sharpest firepower, and the firepower network intertwined with a large number of beam weapons and Rayser firearms will be the most important means of killing and injuring the enemy's vital forces.

The third layer is a bit special, it is difficult to see in the land base of the ordinary Zaka Zerg, which can be regarded as He Zhiyuan's own creativity. The firepower on this level is dominated by melee weapons and various support items.

The so-called melee weapons are mainly composed of modified land chariot mechanical arms, and will be equipped with melee weapons such as light fangs. These fast-moving robotic arms, combined with indestructible fangs of light, form a terrifying flesh-grinding front on the forward positions of the Vengeance Hive Base, and any enemy who breaks through the long-range firepower network of the Vengeance Hive Base will first face these offensive and defensive mechanical arms.

In addition to the mechanical arm that is mainly responsible for attacking with light teeth, there are also a small number of mechanical arms that hold auxiliary props in their hands, including gravity barrier bombs, high-explosive gas pressure hammers, and even high-ability bombs that can release spiritual shock waves, etc., several auxiliary props that He Zhiyuan feels are the most practical ones that are controlled by a small number of mechanical arms and can be released at any time. These supporters with different functions may be able to do wonders in defensive battles.

And at the end of the forward defensive position, He Zhiyuan plans to install two or three pure energy explosive bombs that can be detonated at any time! This kind of extremely powerful terrorist bomb will become the last defensive means in the forward defense system of this revenge hive base, this kind of super bomb that only kills people and does not damage buildings is really the best thing to use in defensive warfare, and its power will definitely not disappoint He Zhiyuan, especially when used to deal with individuals with super ability, this pure explosive bomb can play a miraculous effect.

The only regret is that the cost of this pure explosive bomb is too expensive, and He Zhiyuan can only prepare a few as a last resort.

Of course, while the forward defensive positions are important, they cannot be the whole of the defense system of the Vengeance Hive Base. Inside the Vengeance Hive base, there is naturally a corresponding defense system as well.

However, unlike the heavy firepower and lethality defense system of the forward defense position, the defense system inside the revenge hive base is to try to avoid using weapons with excessive destructive power - no way, he He Zhiyuan has too thin foundation, so he doesn't want to destroy what little belongings he has.

Because firepower and destruction must be controlled. Therefore, the defense system inside the Vengeful Hive Base is built with biochemical beings as the core. However, this time, He Zhiyuan borrowed the idea of the high-level Zerg Kuys, and prepared to equip his biochemical and biological troops with Zaka Zerg guns and other weapons - these individual weapons are actually quite cheap, but they can directly increase the combat effectiveness of He Zhiyuan's biochemical and biological troops by a notch, which is definitely a good idea for He Zhiyuan, who has always taken the route of elite soldiers rather than the route of the sea of soldiers.

The defense system inside this revenge hive base obviously cannot be compared with the defense system of the forward position of the base, but in He Zhiyuan's opinion, once the battle is carried out inside the base, it must not be a positional war. Defenses inside the base. Mobility and flexibility are far more important than the defense capability itself.

A small amount. Powerful armed biochemical creatures combined with some static defenses of precision strikes, plus the cooperation of some real guards, this is the internal defense system of the Vengeance Hive Base.

Thinking of this, He Zhiyuan suddenly remembered that he had been an opponent with him. A high-level zerg who has done business with himself again. The third-level commander of the Zaka Zerg, Kuys Steelfang.

This high-level zerg when they left the underground labyrinth of Pegomi. He Zhiyuan once left a contact information, but now that I think about it, this high-level zerg can completely come into contact with it. At least for the construction of their own base, this high-level zerg will definitely be able to help a lot. I just don't know if this high-level Zerg who looks like a profiteer is willing to help him, or how much does it cost to pay to invite this high-level Zerg......

Shaking his head, He Zhiyuan put this thought behind him for the time being. The reason why he rushed back in such a hurry, and as soon as he came back, he plunged into the command tower of this base, carrying out these boring defense arrangements and construction, and even Little Lori Mo Yan didn't go to see him, in order to be able to build the defense system of the revenge hive base in the shortest possible time. As long as the general framework is built, the rest of the specific and tedious work can be handed over to the highly intelligent Zaka Zerg command brain to complete, and when the time comes, He Zhiyuan can free up time to do something else.

The establishment of a defense system is the first step in the fortress of the revenge hive base, this step He Zhiyuan has been roughly arranged, with his instructions one by one, the command brain has begun to work rapidly, and the rest is nothing more than a matter of energy consumption and time.

After establishing a relatively complete defense system, the fortressification of this revenge hive base can continue, and it is impossible to rush it, at least for the time being, it is obvious that more can be done - only after the level of the mechanical firepower arsenal is raised, He Zhiyuan can do more.

At present, the most important thing for He Zhiyuan is still to cultivate junior giant creatures.

In the cultivation plan formulated by the mother emperor He Zhiyuan, a considerable number of varieties of primary super-energy creatures need to be cultivated in an environment full of active energy, which cannot exist naturally and can only be artificially created.

Of course, with the technological level of the Zaka Zerg, it is not difficult to create such a cultivation environment. It's just that if you want to create such a cultivation environment, it will definitely consume a lot of energy and raw materials.

But it is clear that although it is already known that artificially creating such an environment will consume quite a lot of energy, He Zhiyuan still underestimates the intensity of this consumption a little. Therefore, when he made a request to the command brain, the command brain immediately gave a reply that made He Zhiyuan frown: creating the artificial environment that He Zhiyuan needed - even if it was only barely meeting the requirements - would require at least 50 million calories of energy and more than 100 tons of raw materials.

This is a very fatal number for He Zhiyuan. When He Zhiyuan first returned, the energy repository of the Revenge Hive Base stored 20 million calories of energy and 50 tons of raw materials. But after a series of constructions, this figure has been reduced to fifteen million calories and thirty-five tons. Moreover, it is conservatively estimated that when the defense system of this revenge hive base is roughly established, it will still need to consume about five million calories of energy and about twenty tons of raw materials. In this way, there is no extra energy and raw materials to complete the artificial cultivation environment, not to mention, in addition to the defense system, this revenge hive base also needs to establish a reconnaissance system, logistics system, power system and other systems to make this revenge hive base completely fortressed, which requires a lot of energy and raw materials.

He Zhiyuan left the Vengeance Hive Base for more than half a month, and the people of the Black Dragon Society collected 20 million calories of energy and fifty tons of raw materials for him. Almost every day, more than 1.3 million calories of energy and more than three tons of raw materials can be received. At this rate, it would take at least a month to build the artificial cultivation environment at least if the energy requirements of the defense system were met - and this was at the expense of the construction progress of all systems except the defense system.

All in all, He Zhiyuan once again felt that he had become poor, and it would take at least a few months before this poor situation could be slightly improved. But...... In a few months, who knows what will become of this world? Maybe the Beast God and the Zaka Zerg have already been divided, and even if this world has been destroyed by the Zaka Zerg or the Beast God, it is not known.

"10,000 years is too long. Seize the day!" He Zhiyuan muttered hatefully. He touched his chin again and said to himself, "Maybe I should talk to Bai Tongsheng and Kuroko." How can we quickly expand the power of the Black Dragon Society......"

××××××××××××××××××××××××××××××××××××××

"Poof. Scold. ......"

When He Zhiyuan walked out of the base control tower, a small figure flew over and crashed into He Zhiyuan's arms at once. Naturally, it's little Lori Mo Yan.

More than half a month ago, He Zhiyuan went to the Great Valley for an adventure without saying goodbye, which made Little Lori very unhappy. In the past half a month, this little Lori doesn't know how many times she has cursed He Zhiyuan in a circle in the corner, and the little girl has even made up her mind not to pay attention to He Zhiyuan anymore.

But when it was discovered that He Zhiyuan had come back - although He Zhiyuan entered the base control tower as soon as he came back, he had built so many things, and the disturbance was not small. Only He Zhiyuan can enter the command tower of this base, and only He Zhiyuan can build the construction in this base, so once a building in the base starts to be built, everyone can immediately know that He Zhiyuan is back - Xiao Lori immediately forgot the curse she had against He Zhiyuan, and the oath she once made not to ignore He Zhiyuan.

"Big villain, go for a long time, and don't say anything!"

Holding the fragrant little Lori, listening to her sobbing complaints, He Zhiyuan only felt that his whole body was going to soften - he really had no resistance to this little Lori.

"Okay, okay, you didn't mean not to tell you, it's too dangerous...... Okay, okay, Brother He knows it's wrong, won't it be next time, okay?" comforted him for a long time, and promised the little Lori to go to her as soon as he finished his errand, He Zhiyuan finally got rid of the little Lori's entanglement, and looked at the sunspot and the others who had been waiting for him for a long time not far away.

"Congratulations to Lord He, my lord has obviously gained a lot from this trip. "The first to catch up was Yu Ji. This traitor of the Yu family has completely regarded himself as He Zhiyuan's number one dog leg at this time, and it is obvious that this thing has been quite moisturized in the Thunder Dragon Society.

"You're doing a good job. Facing Yu Ji's flattering smile, He Zhiyuan patted him on the shoulder and said with a smile. He was really sincere in what he said, in the sabotage operation carried out by the Canglong Inquisition in cooperation with the local indigenous forces in Chifeng City against the rudder of the Thunder Dragon Society, it was precisely by relying on the performance of the two people that the rudder of the Thunder Dragon Society was able to clear this enemy in time, and did not let the rudder of the Thunder Dragon Society suffer any major damage.

If it weren't for the Fire Scorpion and Yu Ji, maybe the Thunder Dragon would really be in a big trouble, and the energy storage in He Zhiyuan's revenge hive base would not be able to store so much energy and raw materials.

Who would have thought that this young master of the Yu family, who had almost killed He Zhiyuan and almost died in He Zhiyuan's hands, would become a loyal dog of He Zhiyuan, and made a contribution to him, it is really difficult to predict.

"It's an honor for my subordinates to be able to serve Him!" Being patted on the shoulder affectionately by He Zhiyuan, Yu Ji suddenly felt that his bones were a little lighter, and he hurriedly expressed his loyalty. He lowered his voice again and said, "Lord He, during your absence, the head of Baitongsheng and Vice President Luluo Yan have already left with their subordinates. ”

"Oh?" He Zhiyuan raised his eyebrows, slightly unhappy. The remnants of the three major forces led by Bai Tongsheng and Luluo Yan have always been the force he relies on the most, and if he wants to rapidly expand the power of the Thunder Dragon Society, he is also indispensable for the help of these masters, "Why are you in such a hurry?"

"How dare your subordinates?" Yu Ji hurriedly explained, "Your Excellency may not know yet, right? The first thing is that the beast god was born again, fighting the demons outside the sky, which is rare once in a thousand years...... Of course, this is too far away from us, and there is not much to say. ”

"But my subordinates heard about it, just a few days ago, Zhi Tianluo, the president of the Warcraft Master Association, suddenly announced that he had resigned as the president of the Warcraft Master Association and was going to retreat and cultivate. The reason why the head of Bai Tongsheng and the vice president of Luluo Yan left in a hurry was mostly related to this incident. (To be continued......)
