Under the heavy eyes of everyone, the giant holographic image screen of the command center platform displayed data information reflecting the battlefield situation in real time.

"The total energy value of the Demon Army's attack: 50,007,200 TNT equivalent, of which the effective attack energy value of the hit shield is 16,008,100 equivalent, the shield loses 80.32% of the defense power, and the completeness is 83.8%, which can resist 4.32 attacks of the same amount...."

"There is no wear and tear on the shield assembly, and the units are working well. The city's defenses did not appear abnormal in the tremors...."

"The production system is normal, the factory pass rate of the defense component production line is 99.999995, and it is not affected by vibration, and the protective cover assembly can be replenished when it is safe..."

....

A group of data, the entire Hanzhong City's external protection system, internal city defense system, logistics production system, garrison and resident operation and other data in the air constantly appeared, and constantly updated, in the most direct and objective way such as charts, no need for words to explain, everyone present can understand all the situation of Hanzhong City at a glance.

According to the strategic plan that has been drawn up and the overall deployment of the central computer, everyone is silently doing their own thing, the command, the coordination of coordination, and the arrangement of the arrangement.... Everyone has their own positions and responsibilities, and the most responsible among them is, of course, more than 100 people in the core area of the command center, all of them are the core members of the Blue Star Clan, and almost all of the more than 100 members of the Blue Star Autonomous Group were gathered together at this time.

At this time, everyone was silent, looking at the information system on their respective command platforms, and sending instructions to their respective systems through the computer.... Everyone was silent, and the only sound in the center was the humming of the chassis when the giant supercomputer was running, the electronic reminder when the screen information popped up, the muffled sound of the air conditioner running, mixed with a little whispered conversation, and the atmosphere was a little solemn.

Soon, it seemed that everyone's voices had stopped, and after a short suffocating pause, another dull loud bang erupted over Hanzhong City, and the entire underground headquarters trembled, and a little dust fell from the ceiling, even at a depth of 50 meters underground, thousands of people in the center still felt a violent explosion from above the city.

"The total energy value of the second round of attack of the Demon Army: 52,048,900 TNT equivalent..."

The artificial intelligence computer faithfully reported the data of the current battlefield, and at this time, some commanders and fighters had already begun to send maintenance teams to various places at the base points of the city's protective shield to carry out maintenance work on the over-consumption formation. Every attack of the demon army, although the protective shield of Hanzhong City can be resisted, but at the same time it consumes a lot of energy, it will also consume the functional components of the magic circle, if these components are not replaced in time, it will reduce the effectiveness of the entire protective shield, once there is a problem, the consequences are unbelievable.

The protective shield used in Hanzhong City is a super protective shield developed by Blue Star Country after years of hard work. This powerful protective shield can cover an area of thousands of square kilometers, from 5 kilometers in the air to 1 kilometer underground, which can provide all-round three-dimensional protection. The protective ability of its shield is the strongest, and it can resist the equivalent of a 300 million equivalent nuclear explosion attack at one time, which can be described as the strongest defensive energy shield in the history of the Spirit Star.

The strongest defenses naturally require the greatest amount of energy. In addition to continuing to rely on the underground spiritual veins of Hanzhong City to provide spiritual support, the energy provided for this set of protective shields mainly relied on the core secret of the Blue Star Country, the Blue Star Stone. This super gem was hidden in a secret factory at a depth of 100 meters under the Blue Star Castle, which was heavily guarded, huge and complex, and was the fundamental source of energy power for the entire Blue Star Country, and at the same time provided the most powerful and sufficient power for the protective shield of Hanzhong City.

Theoretically speaking, if the demon army wants to break the protective shield of Hanzhong City, it is impossible to break the protective shield unless it can come up with an attack force of more than 300 million at one time. Of course, the demons of the upper realm can easily do this, but the demon army that came to the lower realm is not so well equipped, and in addition, the Heavenly Demon King may be able to do it if he uses super magical powers, but don't forget, there is also a super strong person like Linda in Hanzhong City, and the Heavenly Demon King will never risk the cost of mana to do such an extremely dangerous act, and Linda is ready to move inside. Even without Linda, as long as the Blue Star Army took advantage of the Heavenly Demon King's mana to launch a deadly nuclear counterattack, she would face great danger. Therefore, it is basically impossible for the Heavenly Demon King himself to take action in person.

The only way for the demons to break through the shield is to continuously launch repeated and fierce attacks on the shield, and consume the Blue Star Army's protective reserve energy as much as possible. Of course, it was impossible for the Heavenly Demon King not to know that the Blue Star Army had the infinite energy source of the Blue Star Stone, and all they had to do was to consume the protective shield formation weapon. Every time the shield is faced with a huge attack, some of its various parts will be burned due to energy overload, and it is not so easy to manufacture these components, and at the same time it is expensive and complicated, the Blue Star Army will never have so many components to back up, they will always run out of use. Once that time comes, the shield of Hanzhong City will be self-defeating, and that is also the time when the demon army will launch a general attack!

The Blue Star Army would not be unaware of the Demon Army's plans, so before the war, they had already produced and stored a large number of shield components in advance, which was enough to meet the tens of thousands of blows of the Demon Army! Moreover, there were more than ten production lines of shield components in Hanzhong City, and they were manufacturing various types of components and accessories every day. Not only that, the Blue Star Kingdom has introduced a part of the production lines of various war readiness materials across the country into Hanzhong City, and at the same time has reserved a large number of war readiness materials and resources, as early as before the siege of the demon clan, all the irrelevant personnel in the city have been transferred, and through all aspects of preparation, the Blue Star Country has transformed Hanzhong City into a super fortress. Their purpose in doing so is to be determined to fight the fiercest and most difficult protracted battle with the demon army!

However, when the war really broke out, the Blue Star Army found that their estimation was still a little more optimistic, Hanzhong City was surrounded by demons, all the backup routes were cut off, not to mention, the attack of the demons was unexpectedly fierce and powerful, on the first day of the demon army's attack, the components of the protective shield had been invalidated.

"If we continue like this, we will be able to hold out for about two years at most. Arden knocked on the table with a little sorrow, and although his tone was as calm as possible, he still couldn't hide some of the worry in his heart.

That night, the Blue Star Clan Convention held a highest-level meeting, and all the members of the Autonomous Group gathered again, this time, the content they discussed was related to the fate of the entire Blue Star Country and the entire Spirit Star.

"Two years to go, that's not bad! I said, we have to be optimistic! Maybe the demon army will last less than two years. Tang Long saw that everyone was not talking, the atmosphere was a little solemn, and said with a smile, but he found that no one responded to him.

"I suggest that you plan a counterattack in advance, and you must weaken the attack power of some demon armies. Schroeder said, and at the same time, several counterattack plans were called up from the computer at once, which were displayed in the form of images on everyone's holographic projection screen.

"I'm afraid it's not so easy to fight back, haven't you noticed that the interception system of the demon army is also very powerful? 40% of the spiritual jamming bombs we launched today were intercepted without exploding. It's not like it used to be, air supremacy isn't on our side. Ivanov shook his head, disagreeing with Schroeder's counterattack.

"Then find a way to break through the interception of the demon army, if you can't do it, just use nuclear weapons! We can't just watch them bombard our shields day by day and do nothing!" Schroeder was obviously a little excited, and slammed the table.

"Nuclear weapons cannot be used casually, we have not many warheads in stock, they must be used at critical moments, and the speed of production is greatly affected. What's more, even if we can break through the interception of the demon army, we will only fight those vassal demons, and they will not have much impact on the attack of the main force of the demon army, and they can also create more cannon fodder. Connell shook his head and questioned Schroeder's plan.

"But we can't do nothing. I agree with Schroeder's counterattack plan, but it must be carefully planned, and every counterattack must be swift and powerful, and must not fail. The most important thing now is how to organize the counterattack force in the rear and launch a few disruptive combat operations on the flank, which may help us divert a part of the demon army. Still, Arden affirmed Schröder's point.

"The counterattack force in the rear? Alas, old man, you don't know, the demon army has sent zombie legions to harass our rear for many years, and often sends elite troops to attack our eastern region, and now we have no rear and front line, and the military and civilians in the entire eastern key areas are now all retreating to the city, adopting a passive defensive posture, and no one dares to leave the protective shield of the city for half a step. It takes a lot of troops to defend these areas, and we don't have enough troops in the rear, and I'm afraid we can't organize a sufficient number of offensive troops. Danny said helplessly.

"What about the other allies??!?

"Allies, now whether it is the Xiluo Alliance or the Middle-earth Alliance, it is difficult to protect itself, and the Tiannan Alliance of the Ye Clan is also in danger, not to mention the Sea Clan, Beamon and Zerg, everyone's fate is hanging by a thread. The only rear we can count now is the Kopu country and the mermaid country. But these two countries are also struggling to support in front of the vassal sea clan of the demon army, if it weren't for the fact that the main force of our navy is still there, and modern can still withstand it, I'm afraid these two countries would have fallen a long time ago. The demons are terrifying! their demonic abilities can fundamentally change the comparison between friend and foe..."Sonia shook her head, a little dazed, she didn't want to face the situation of total defeat in front of her, but this is the reality!

"Then what are we going to do?!Are we just going to sit back and wait?!Or wait until the end and die with the demons?!We have to find a way to defeat the enemy!" Arden scolded a little annoyed, and he slammed the table hard, shaking the control platform so that even the holograms released were intermittent for a moment.

The old man's anger was really rare, and he was indeed a little anxious, and his attitude couldn't help but frighten everyone, and everyone fell silent again. The battle has been fought so far, the enemy is too strong and terrifying, and it is not easy for the people of the Blue Star Country to hold out for so long, and they really can't think of any better way to fight back.

"Perhaps, we have one last hope..."

The two figures sitting in the corner slowly stood up, like the sound of heaven, and attracted everyone's attention for a moment.
