"Your Majesty, this is a secret room that I made specifically to protect the transmission channel. It uses materials that iste the power of space. Even True God Hunyuan cannot directly enter it. It is also the most defensive ce in the entire fortress." Zhuge Liang Pointing to the heavy stone gate in front of him, he introduced to Du Yu.


    The material value of this power to iste the space is not cheap. Just a palm-sized and one-finger-wide area requires 500 yuan, and to build such a heavy gate, the cost is absolutely not It will be under 500 million.


    To convert into a mixed element value, it takes a full 50,000 mixed element value, and only the Kylin Empire is so rich and powerful that it can sustain such a consumption.


    If they change to Aoyun Nation, their treasury will bepletely emptied.


    "Well, well done." Du Yu admired.


    Zhuge Liang stepped forward and opened the stone door for Du Yu. Behind the stone door is a huge secret room. The center is the fixed space passage.


    At this moment, the Zhentian Seal floating above the passage is no longer as simple as shaking, but is beginning to emit ripples.


    Seeing this scene, Zhuge Liang''s face suddenly changed, and he solemnly said: "Is the attack strengthened again? The ghosts and gods on the opposite side are definitely attacking by more than one Peak Hunyuan True God. There hasn''t been such a powerful one before."


    Du Yu was not surprised. He said tly, "This is normal, isn''t it? After all, this is their only chance toe over. For ghosts, our souls are their great tonic. Come to us and go with us. It doesn’t make any difference to break into the secret realm to find opportunities."


    Zhuge Liang also understood, but the strength of the opposite ghost caused him to worry about this seal formation.


    If the formation can''t stop it, the Kylin Empire, which is leaning against the passage, will be the first to bear the brunt. Faced with a group of ghosts and gods, they will definitely be wiped out in an instant.


    Even the overlord force ranked first in the highest ne, dare not say that he can withstand the impact of ghosts in the entire sub-world.


    "Tiandao Zhinao, I need to arrange a directional teleportation array. What is the price?" Du Yu asked.


    "Ordinary directional teleportation array, the price is 50,000 yuan, the directional teleportation array that can carry the strong, the price is 100,000 yuan, and the directional teleportation array that can forcibly transmit the true **** of the hybrid, the price is 500,000 yuan." Tian Dao Zhi Nao replied.


    hiss


    Du Yu took a breath, and the price of this forcedly teleported directional teleportation array was actually ten times that of the ordinary teleportation array!


    What a terrifying number this is, if converted into essence, it would be 5 billion.


    The total assets of Aoyun Nation are nothing more than that. A teleportation formation has hollowed out a preliminary force, which shows how much the cost is.


    If it hadn''t been for the few waves of gains, he was afraid that he wouldn''t be able toe up with so much mixed value.


    Of course, Du Yu now has only a mixed yuan value close to 200,000, and the remaining 300,000 still needs to be exchanged with Tiandao Zhinao.


    Although it was a loss, it was not a level at allpared to the gains of sessful negotiations. Even if Du Yu was at a loss, he would grit his teeth and pay.


    "Heavenly Way and Brain, I need to exchange some Hunyuan Value" Du Yu said painfully.


    Soon the 300,000 mixed yuan value was obtained. Looking at the full 500,000 mixed yuan value disyed on the light screen, Du Yu couldn''t help feeling that this was definitely his biggest one. One-third of his total assets, just It was used up like this.


    "Start building a directional teleportation array!" Du Yu said.


    "Obviously." Tiandao Zhinao''s voice sounded, and then countless materials flew out of Du Yu''s space, and began to quickly merge along the sub-world channel, forming arge number of runes around, forming a huge array.


    Du Yu was also carefully observing theyout of the formation with his spiritual knowledge and learned from the experience of the formation. I have to say that the way of the formation of the heavenly wisdom brain is very simple and rude, and Du Yu can learn a lot of hard knowledge from it.


    This is of great help to his formation learning.


    A formation that wasparable to the 7th Pinnacle Grand Formation waspleted smoothly in just ten minutes.


    Compared with an ordinary formation mage, who usually spends ten and a half months in the formation, Tiandao Zhinao is as efficient as sitting on a rocket.


    Looking at thepleted formation, Du Yu sighed: "Hey, I didn''t expect it to bepleted so quickly. If the time is a little longer, I might have the opportunity to attack the qualifications of the seventh-rank formation mage."


    Xiao Lingughed out loud. She was already ustomed to Du Yu''s learning speed, and saidfortingly: "Isn''t there a formation outside the fortress? Anyway, a seventh-rank formation is enough. , Then you can study hard."


    Du Yu''s face suddenly became bitter: "The formation that can block the Hunyuan True God''s attack requires at least the 7th-Rank, and it will cost a lot of resources. It seems that we must find a way to recover the blood. This is not enough. ."


    With his current financial resources, he can only buy the formations of the seventh rank at the moment, and at the high formations, he needs to bankrupt his family.


    However, this formation does not need to be too high. After all, what he has to face is the powerhouse of the entire supreme ne, and the effect of the formation is actually not too great.


    This formation is just to block the first wave of attackers. There will definitely be unbelieving forces who will send people to test him. What Du Yu has to do is to repel them and fight back fiercely.


    The purpose of the directional teleportation array is exactly the same.


    After arranging the directional teleportation array properly, Du Yu took the two daughters and Zhuge Liang to the tall wall of the fortress. On the wall, the space needed to arrange the array was already left.


    Moreover, there are also materials that can increase the power of the formation. It can be said that Zhuge Liang has considered everything properly, and there is no need for Du Yu to worry too much.


    Du Yu pointed to the route on the ground and joked with a smile: "Kong Ming, when the highest ne is beaten down in the future, I will arrange you to design buildings. I didn''t expect you to have this talent."


    Zhuge Liang hurriedly waved his hand: "No, no, please forgive me, your Majesty. The design of this thing has caused me a headache for a long time. After considering the scale of many formations, I designed this pathway. This is almost impossible. It''s killing me!"


    Naturally, Du Yu would not be willing to let such a talented person be an architect. He patted Zhuge Liang on the shoulder and said, "Well, you can contact the current royal family of Aoyun Country and take over their intelligence system. I want to Be aware of any turmoil in the country at any time."


    The current situation is tense, and Du Yu doesn''t dare to be careless. He is sure that there will be a lot of troubleing to the door in the near future, so the big forces will definitelyunch a few death-dead people to test whether what he said is true.


    "Yes!" Zhuge Liang said respectfully, and stepped back.
