Tang Dingyuan pinched a handprint in the void. In the deep star map, a large number of crystal clear star ship structure drawings with golden lines emerged immediately.

Ten years ago, in the process of pursuing the firefly, the claw fleet of night orchid was raided from behind by the federal fleet led by Ding lingdang, and the whole army was annihilated.

In that war, the Federation captured a lot of imperial soldiers. Through their interrogation, they got a lot of information about the black wind fleet. These information went back and forth to the firefly, which made the people in exile have a general understanding of the strength of the black wind fleet.

"The technological strength of the human empire is higher than that of us and the Xingyao Federation, but it is not so high as to be invincible. This is because everyone has a" technological bottleneck. "

Tang dingyuandao said, "in the past ten thousand years, the technological peak of human civilization was the era of Xinghai empire. It is said that in the process of development, the Xinghai Empire got the help of three volumes of" Fengshen Tianshu ". Almost in an instant, it developed a brilliant civilization like a big bang.

"After the sudden collapse of the Xinghai Empire, the whole human civilization turned into dust debris. Later, all civilizations kept catching up with the height of the Xinghai empire. The closer they got to the height of the Xinghai Empire, the slower their development speed and the more bottlenecks they encountered.

"This is true of the Republic of Xinghai, and so is the Empire of human beings.

"In the past 1000 years, although the human Empire has made great progress in various fields, its overall civilization level is not much higher than ours, and it has almost stagnated in the last few hundred years.

"Xingyao Federation is different. It has leaped from a single world civilization to a seven world cross star civilization, and gained a lot of technology from the ruins of Kunlun civilization. In the past 100 years, the Federation has experienced a golden period of development like a big explosion. Today, although it is still a little bit behind the Empire, it has the ability to deal with each other, It's just like the difference between bronze saber and steel saber. Backwardness is backwardness, but it can also kill opponents!

"This is the current balance of power between the two sides - the black wind fleet has higher level of starships, more firepower, and more powerful people on board. It is also a deep foreign combat, an attacker, with more diversified tactical options, without any scruples and burdens. On the surface, it has completely mastered the battlefield initiative.

"However, they have a fatal weakness. They lack a strong enough rear area. They go on an isolated expedition and go deep into the enemy's rear area. Apart from burning, killing and looting on the spot, there is no possibility of any supplies.

"In the final analysis, the intelligence of the black wind fleet was wrong. When they set out a hundred years ago, they thought they were just going to conquer and develop some uncivilized world, and they could not even fly out of their own galaxy. However, they did not expect to meet the star shining Federation, which is a very tough hand, and might bite back!

"It's impossible for the black wind fleet to fight a protracted war. If one of their star ships blows up, there will be one less. If one of the strong falls down, there will be one less. There will be no supplement at all! Even if they drained all the blood of the Federation in the protracted war, they themselves were exhausted to the extreme - that was not what the commander of the black wind fleet wanted to see.

"Therefore, for the black wind fleet, the most likely strategy to choose is to jump to the hinterland of the Federation by surprise and seize one of the seven worlds of the Federation with the momentum of lightning and thunder.

"As long as we have a world as a strategic fulcrum and logistics base, with the black wind fleet higher than the Federation and our military strength, we can continuously refine more star ships, arm a large number of slave soldiers, collect sufficient resources, support them to constantly erode around, force the main force of the Federation to carry out a strategic decisive battle, and win or lose the first battle!"

"It's almost an inevitable strategy, but it's also a very risky strategy, because the moment of jumping from hundreds of light-years to the hinterland of the Federation is the most vulnerable moment of the black wind fleet - if anyone doesn't understand, imagine a giant cosmic dinosaur, crossing a rugged and narrow canyon.

"As long as this" cosmic dinosaur "goes through the canyon smoothly, it can hunt and kill without fear.

"However, when it is stuck between the rocks and crevices in the canyon, it is the weakest time. Even the weaker beast can seize the opportunity to kill it!

"This is the only chance for us and the Federation!

"As far as the Federation is concerned, it does not want to fight a protracted war and turn its territory, which has been painstakingly built for a hundred years, into a piece of scorched earth. After all, the black wind fleet is only an expeditionary force of the human empire. Even if the black wind fleet is eliminated, it may face new threats.

"The Xingyao Federation must maintain a certain strength before it can have the chips to play the next game with the real Empire, so that the Empire does not dare to send a second expeditionary army rashly.

"To solve the black wind fleet cleanly in a decisive battle, to obtain a large number of black wind fleet's starships and materials, to complete a new upgrade, and to really have the confidence to talk with the Empire - this is probably the most perfect outcome envisaged by the federal side.

"With all the current military forces of the Federation, if we can predict which world the black wind fleet will jump to, and carry out a devastating strike in the process of the other party's star sea jump, there is still hope to achieve this strategic goal!

"So, to simplify the coming war, it's actually a game of" one out of seven ". The Federation wants to bet on which of the seven great worlds the black wind fleet will appear, and dispatch all the elite to this great world in advance.

"If you win the bet, the Federation will win the final victory if the black wind fleet" half crosses "and destroys the other side in the ripples of the four-dimensional space when it jumps across the sea of stars!

"If you make a wrong bet, and let the black wind fleet successfully complete the sea of stars jump, completely launch the battle formation, and even occupy a certain world, it is equivalent to the" cosmic dinosaur "crossing the canyon, and the ancient landing army successfully established the" beachhead position ", and the Federation will surely be defeated!"

Tang Dingyuan said here, a meal, to the lower hand: "excuse me."

A senior professor from Xinghai University, who is also a senior member of the parliament, asked: "in this case, is it possible to set up an ambush in the seven worlds at the same time and plug all the loopholes?"

With a smile, Tang Dingyuan shook his head and said, "it's impossible. Our military strength and that of the Federation are weaker than that of the imperial expeditionary force. If they are divided into seven groups, they will be even weaker. They can't resist the enemy. They will only be eaten by the black wind fleet.

"Let alone divide the forces into seven routes, even if the elite forces are divided into two parts, it is impossible to achieve the strategic goal of interception and encirclement and annihilation. Only when all the elite forces are gathered together and clenched into a fist, can it be possible to smash the jump and expansion of the black wind fleet!"

The professor frowned deeply and said, "there are seven worlds in the Federation. The black wind fleet can choose any one to carry out jump attack, but we can only choose one of them to ambush. It seems that the situation is quite unfavorable to us."

"Not really."

Tang Dingyuan once again manipulated the light curtain, showing the basic situation of the seven great worlds of the Xingyao Federation. Each gorgeous and colorful star appeared in front of everyone. "You see, although the Xingyao Federation has seven great worlds, not all of them are suitable to serve as the headquarters of the black wind fleet.

"This is the world of tree sea. The parent star tree sea star is covered by the primeval forest, and its development level is very low. There is not much industrial foundation for magic weapon refining and resource collection. The local people are excellent veterans. They are good at cooperating with spirit beasts to fight together, but they are useless to the black wind fleet.

"Even if they occupy the Shuhai boundary, it is difficult for the black wind fleet to collect enough resources to strengthen itself in a short time. On the contrary, they will be trapped in the virgin forest.

"Therefore, the Shuhai boundary can be ruled out.

"This is the crystal world, a world rich in crystal resources. The problem is that there are almost no other resources except crystal. The parent star is a vast desert, and even the most precious water resources are extremely scarce!

"Water is the foundation of everything. In many cases, it is even more important than crystal, so there are a lot of crystal resources in the crystal world, and the level of civilization is still not high. When it was discovered by the Xingyao Federation, the aborigines in the crystal world were struggling in the severe drought, and they almost joined the Federation happily to exchange crystal for water resources.

"Although the federal government has been improving the local harsh environment in the past few decades, it is not possible to completely harness the desert into good farmland and develop enough industrial base for the use of the black wind fleet in 30 to 50 years.

"Unless the black wind fleet masters the magic power of casting magic weapons with gravel, the crystal world can also be ruled out.

"Not to mention the netherworld, it is a world with exhausted resources and full of radiation, which is only suitable for ghost repair. After all, the black wind fleet is mostly composed of living people, and it is useless for them to occupy such a world full of dark wind and ghost."

"Among the three core worlds, the blood demon world takes the path of biochemical technology. The facilities for refining various biochemical war animals and skeletal warships are incompatible with the industrial foundation needed by the black wind fleet. Moreover, the blood demon world has a strong indigenous people's livelihood and a large number of people who are good at digging holes and drilling ground. As early as a hundred years ago, it had the strategic preparation of" scorched earth resistance "and really occupied the blood demon world, We also have to face a huge number of guerrillas and rebel forces, which is quite troublesome.

"Tianyuan kingdom is certainly good, but as the capital of Xingyao Federation, its own defense is also the strongest of the seven worlds, and it is difficult to be occupied in a short time!

"To sum up, there are only two targets that are most suitable for the black wind fleet to carry out jump attack, namely, flying star and sky circle!

"Flying star world has two habitable planets, iron star and spider nest star. In the past 100 years, these two planets have developed quite good industrial bases. By the way, spider nest star also has a" thorn Star Studio ", which is the largest cosmological Observatory in the Federation. It has extremely high military value. Seizing flying star world can not only help the black wind fleet rapidly enhance its strength, It can also seriously weaken the power of the Federation, and the victory is in hand!

"Tianhuanjie is the last world to join the Federation. The Federation has been building tianhuanjie for only 30 years, and its influence in the local area is relatively weak.

"It also has a large orbital dock in the era of the star sea Empire, which can provide all the facilities needed by the black wind fleet, help the black wind fleet to strengthen and upgrade in a short time, or refine new star ships!

"Therefore, we may not be facing the game of" one out of seven ", but" one out of two ". We have to guess where the black wind fleet will come from, flying star or ring of heaven!"
