"You deserve to be the overlord of the mainland." Standing above the sky city, Le Feng let out a sigh as he watched the beast tide rushing from all directions. Being able to become an existence that occupies more than half of the area of this continent, the true strength of the Yao Clan is truly manifested at this moment. In just half of the territory, there are as many as three hundred Demon Kings, and the combined strength of the five wise races is not comparable. However, this is also the biggest advantage of the monster race. The wisdom race against the monster race has never relied on the number of the emperor, but the source array, the puppet, the source weapon, the fortress, the pill, the talisman and a lot of auxiliary methods. Just like now, the feather tribe has no more than 30 great arcane masters with ten rings or more. The legend has only three so far. However, relying on the sky city, the feather tribe has come from strength, forcing the demon tribe, which has always been scattered and disorganized, to unite. Save. This is a contest between wildness and wisdom. Tens of thousands of monster races fight against Sky City and the three floating fortresses, and a bloody battle begins. Accompanied by the impact of the monster race, the sky was instantly full of fire and meteors, and there were flashes of arcane magic, the brilliance of source skills, and the collision of weapons and claws, flashing the most moving luster, inspiring the bloodiest in the heart. fanaticism. Le Feng and his partner may be the only ones indifferent. As an observer, his duty is to observe, not to participate in war. Not only to observe the movement of the monster clan, but also to observe the movement of Sky City. Once the war starts, it is the best opportunity to test the defense of Sky City, and it is also the time to observe the loopholes in Sky City's defense. Even though Su Chen had already seen the defense system of Sky City when the poisonous toad attacked Sky City, he was only one person at that time and his vision was limited. After all these years, after Sky City resumes its movement, who knows what will change? At this time, the defensive cover of Sky City has been fully activated, the Sky Feather Sun Cannon and the Black Brake of Extinction began to roar, the feather army formation, a rain of arrows fell from the sky like a roof, and the arcanists all performed the defensive arcane arts for Soldiers and cities blessed with shields. The offensive and defensive Sky City takes the term steel fortress to its extreme. Massive attacks are vented at all times. The source of energy is like swaying without money, and the source of energy is stormy, and there is blood everywhere. The fire was vast. Le Feng's eyes still swept across every corner coldly. Observers focus on loyalty first, followed by insight. Le Feng once killed a purple-eyed golden eagle, and after refining its bloodline to achieve the magic phase, he obtained the ability of its purple-eyed celestial purpose. When it was running, there was no different phase outside the body, but the pupils turned purple. Under these purple eyes, Le Feng's eyesight can become extremely far away, and it is difficult to detect any concealment and camouflage means. Observing with all his strength at this moment, the surrounding scenes of Sky City are in sight. Le Feng silently observed, recorded, and recorded it with the special secret words of Wujizong. The two Feather soldiers who followed him were not surprised to see this situation. This is a mutually agreed power. The Human Race can observe the Yu Race, and the Feather Race can also observe the Human Race. Of course, what you can observe depends on your abilities. At this time, the forerunner of the Demon Race had already lost all of their losses in the offensive, but for the huge Demon Race troops, this was obviously just a drop in the bucket. The frontline troops have not yet died, and a new wave of Yaozu troops has arrived. The main force this time is the Iron Rhinoceros. The armored rhinoceros is always the best unit to use in battles. Their powerful defense and terrifying impact can bring huge impact to the opponent every time the battle is in battle, even if they can’t break through the defensive cover of Sky City, they will also bring a huge impact. Consumption. Then I saw that with the charge of the iron-clad rhinoceros, the defensive cover of Sky City burst out with a colorful light of energy from time to time. Ninety-nine arcane towers light up in turn, supporting the existence of the defensive cover, and the arcanists in them are constantly rotating. Under this powerful attack, the source of Arcanists is always exhausted. Naturally, a substitute arcanist will drag it out and replace it by himself. The brilliance of the arcane tower is therefore always bright and dark, and the guard of the defensive cover is always strong and weak. Occasionally, there will be a gap, and the iron-clad rhinoceros will take the opportunity to rush into the city and kill all sides. At this time, the melee units of the Feather clan will come forward to block with all their strength, forming a new round of shopping. "Although the block defense prevents Sky City from being broken and collapsed across the board, it also makes Sky City's defense not invulnerable. As long as a high-intensity attack is aimed at a certain point, it can still be achieved quickly in a short time. The upper limit of its support, thus destroying the defense in this area." Le Feng said. The Yu clan soldier guarding nearby snorted and ignored him, obviously not convinced. However, discipline did not allow him to talk to Le Feng at will, so he could only ignore it. Another Yu clan soldier beside him was a bit young and vigorous, and he couldn't bear it. "What if it is broken? As long as the foundation stone of the source formation is still there, the defensive cover will be restored at any time." "Qing Ye!" The soldier stopped. Le Feng smiled and said: "Don't be so nervous, do you think I don't know about this kind of thing? Don't forget that the sect master had personally experienced the desert beast siege in the past. How could he not know something like the foundation stone of the source array? Even with the hand of the Demon Emperor's Deep Blue Flame, he destroyed a city wall and the foundation stone of the source formation." "That was the year!" Upon hearing this, the two feather soldiers were excited: "I want to use this again now. It is impossible to destroy by means!" "Is it because you reinforced the foundation stone of the source array again?" Le Feng asked with a smile. The two soldiers stopped immediately. Le Feng has already got the answer. Things in the world are not uncommon to put it bluntly, and offensive and defensive matters are nothing but headaches. At that time, Su Chen took advantage of the deep blue flame pit and brought a lot of losses to the feather clan. Afterwards, he reflected on the lesson and ordered the feather clan to make additional reinforcements on the foundation stone of the source array that supported the defensive cover. However, this kind of reinforcement is not without cost. While protecting the foundation of the defensive cover, it actually leads to an increase in the access to the foundation stone of the source array and an increase in consumption. Only in the eyes of the Yu clan, this is obviously worthwhile. Seeing that he had reached the point, Le Feng smiled slightly, took out the notebook and wrote it down: The base consumption of the defensive cover has increased. The offensive and defensive of the city head continues, but there will not be much change in a short period of time. Both sides are giving their lives, but the monster clan side is obviously higher than the feather clan side. But whether it is a monster or a feather clan, what they pay is low-level cannon fodder, and there is no real strong one. Lefeng had no intention of watching the battle, but looked towards Yongzhou Palace. At the end of the Yongzhou Palace, wisps of white smoke are emerging. Lefeng knew that the white smoke was caused when the Sark energy nuclear was running at full capacity. At that time, Su Shen had seen the Sack Energy Nuclear, so it is not clear. However, after obtaining the manufacturing drawings of the secondary Sac energy nuclei, I understood the structure of the Sac energy nucleus, so I knew that the smoke was caused by the transformation of the source energy of the Sac energy nuclei. Because the source energy of Sack energy nuclear conversion is too large, some source energy conversion is incomplete, thus forming the wonder of source energy smog. It's just something wrong. According to the suzerain, the Sac energy nuclear transformation source can be formed extremely densely. If it is foggy, why is the smoke so thin now? Although there may be differences in terms, Le Feng believes that Su Chen would never describe such wisps of white smoke as a foggy sky. Looking at the smoke, Le Feng bowed his head in thought, and the words that Su Chen had said to himself before he left echoed in his mind: "Sky City was imprisoned and unable to move because they anchored the sea of source energy and gained endless energy. .Although they have lost their mobility, they still have the benefits of energy. After Sky City resumes movement, the anchor chain will inevitably be retracted. In other words, although they gain mobility, most of the endless energy does not exist. But no matter what. In other words, after all, they have mastered the technical ability to anchor the sea of source energy. Therefore, at a critical moment, it may be possible to re-anchor the sea of source energy. This requires you to observe and see if they have such ability. , How long will it take to re-anchor, this is the top priority for your observation area..." Su Chen's instructions are still echoing in his brain, and Le Feng's eyes are still scanning. If the anchor chain is retracted, Sky City will not be able to obtain energy directly from the sea of source energy, and the transformation energy of the Sark energy nucleus will be greatly reduced, which can explain why there is so little white smoke now. If this is the case... Sky City's defensive cover should not last long. Le Feng thought. He was walking around in his spare time, waiting, and looking forward to it. He is looking forward to the attack of the monster race, which can bring enough pressure to Sky City. When the pressure was too high, Sky City couldn't bear it, and re-anchored Yuan Nenghai. This wait is one day. The Yaozu's troops seemed to be endless, wave after wave of attacks. The ground of Sky City was full of blood corpses, but the subsequent tide continued, and the level of the attacking monsters was getting higher and higher, and the lord-level monsters had begun to join the battle group. The Feathers guarding the city have also changed for two waves. Now it is the Guardian of the Feather Gods who is taking over from the National Defense Forces. Standing behind, you can see the wounded soldiers of the Feathers wailing everywhere. The anchor Le Feng was looking forward to did not come. Instead, some new weapons of the Yu clan made Le Feng's eyes shine brightly and recorded them one after another. The two Feather soldiers were very angry at the observers recording their own fighters' secrets, but according to the agreement between the two parties, as long as they were not forcibly breaking into an inaccessible area, the observers could record everything that appeared openly on the battlefield. So they can only watch and endure. When the night came, some changes finally took place in the war. It was not that the anchor was dropped, but the sky city suddenly moved. This move is a great thunder. boom! Sky City rumblingly moved like this, and rushed forward in this way. Go ahead! The huge city itself is a terrifying weapon, like a warhammer in the hands of a god, smashing into the battlefield on the opposite shore. This was the opportunity that Sky City had waited for a day. With the help of night vision decline, Sky City successfully launched a powerful raid. With just this impact, Sky City literally plowed a deep ditch on the battlefield, and all the demon races blocking this road were knocked to pieces. Without the shackles of the anchor chain, Sky City's impact distance is no longer limited. The only thing that can stop it is that there are no enemies ahead. Just this collision caused the Yaozu to pay a heavy price, and the low-level troops suffered countless casualties. There were even three demon kings and twelve demon kings who died tragically on the spot. As the emperor's existence, even the spark did not come and bloom for a while, and it died. Of course, as a price, Sky City's own defensive cover also fell violently. But soon, Sky City no longer has to worry about the defensive cover. The smoke behind the Palace of Eternal Day suddenly increased, and the sound of the rumbling anchor chain blasted across the fields. Sky City, anchored.
