Naga said unwillingly: "It's a pity that half of it has to be handed over!"

Duan Tao said dissatisfiedly: "This is the price of cooperation! It is inevitable! At least temporarily!"

Naga looked at Duan Tao with surprise, "Junior brother, I didn't expect that your mentality would be so good! This is very rare!"

Duan Tao smiled, "This is not a good attitude, but understanding a basic truth! Senior sister, the most important thing in our business is reputation and not eating alone, right?"

Naga smiled and nodded, "Not bad! Good reputation can retain customers, while sharing benefits with others will not put yourself in an isolated position. Junior brother, I didn't expect you to know how to do business so well! Then I can be more relaxed in the future!" Naga said half-jokingly.

Duan Tao hugged Naga in his arms, "That won't work! You are my housekeeper!"

Naga turned red and glared at Duan Tao.

The fat man on the side rolled his eyes and murmured unhappily: "It's coming again! It's really!!"

Duan Tao said to Naga: "Senior sister, do you see how much we can produce this month?"

Naga thought, "The mining conditions here are good! It should be able to produce about one ton per month!..."

"That's the only one!?" Duan Tao looked disappointed.

Naga gave Duan Tao a blank look, "Do you think a ton is very small? It's a lot!! Do you know how many of these top-grade energy crystals are produced in a month?"

Duan Tao shook his head foolishly.

Naga wrinkled her beautiful Qiong Nose, "It's only 900 kilograms when it's good!!" She couldn't help but glared at Duan Tao fiercely.

Duan Tao was stunned for a moment, and smiled with his forehead, "So that's the case!"

Naga said: "The top-grade energy crystal is an indispensable material for making magical war tools, magic wands, etc., and the market price is very high! If it is a top-grade energy crystal that has been initially purified, the price will double!..."

Duan Tao swallowed his saliva and asked impatiently: "Senior sister, what is the price of this top-grade crystal?"

Naga thought: "The raw ore of first-class crystals is usually one million bis per kilogram!"...~"

Duan Tao was startled, "One million is only one kilogram!" Naga nodded, "This is the price this year, maybe it will be higher next year!!"

Duan Tao said suddenly: "Wouldn't it cost 2 million per kilogram to purify?!" "Yes! Unfortunately, the people here are basically water-based energy crystals! If it is fire-based energy crystals, the price will be 50% higher!"

Duan Tao calculated by himself: "You can produce one ton of energy crystals in a month! Good luck! Even if you only sell mattresses, you can earn a revenue of one billion Bis!! It's so great, so grandma's!!"

Naga smiled pursed her lips, "Junior brother, you've calculated it wrong! The various costs need to be nearly 200 million!"

"Then there are 800 million!..." Frowning, "But the one handed over is only about 400 million! That's a lot!!"

Duan Tao asked Naga excitedly, "Senior Sister, when can I start?"

Naga thought, "We must also prepare equipment and deploy labor, and the construction can be started in half a month!"

Duan Tao nodded and smiled, "Senior Sister, then I'll leave this matter to you!"

Naga smiled pursed her lips, and Yingying saluted Duan Tao, "Affect your junior brother's orders!" with a hint of teasing.

The fire in Duan Tao's heart couldn't help but get ready again.

Naga said to Duan Tao: "Junior brother, I don't think it is necessary to tell Xiyingtuo all the situation truthfully! The benefits here are very great. I estimate that the real scale of the crystal veins is several times higher than that of the crystal veins on the Gold Coast! I am worried that Xiyingtuo will have unfavorable ideas for us because of this!"

Duan Tao nodded thinking, "It's not unreasonable for senior sister to worry! I will pay attention!"

"Senior sister, we have been in for a long time! Let's go out first! Come again tomorrow!"

Naga nodded.

Duan Tao led Naga and Xiaopang to the outside and turned a corner. Naga noticed an object on the left that was obviously similar to the stone gate. This was the stone gate that Chen Chu and Xiaopang had seen when they were exploring the cave that day. Naga saw this stone gate when he came in just now, but Naga was thinking about the crystal mine at that time, so he didn't pay attention.

Naga couldn't help but stop and asked, "What is this?"

Duan Tao stopped, glanced at the stone gate, and guessed: "It may be a secret room here! It should have been built by the person who built the castle! But this stone gate cannot be opened!"

Xiaopang, who was standing beside him, said, "There are no good things here! Only bugs! Very annoying bugs!" Xiaopang looked lingering fear.

"Xiao Pang, have you been in?" Naga asked curiously.

Xiaopang nodded, "I have broken a stone door like this, and many bugs rushed towards me!"

Duan Tao couldn't help but feel moved and asked, "Xiaopang, can you still find the stone gate you broke now?"

Xiaopang snatched his big head and shook his head embarrassedly.

Naga frowned and said, "Mining crystal mines will inevitably alarm the things in the secret room! If the things in it can make Xiaopang afraid, I am worried..."

Duan Tao frowned and nodded, "Senior sister, I will come to explore with Xiaopang tomorrow! You will stay in the castle!"

Naga understood Duan Tao’s meaning, and couldn’t help but sigh and said quietly: “Junior brother, isn’t senior sister very useless?”

Duan Tao hugged Naga's slender waist and said seriously: "Who said it? Besides, I can't bear to let my senior sister do such physical work!"

Naga wrinkled her beautiful Qiong Nose and glared at Duan Tao charmingly.

The three of them came out of the cave, and Naga immediately informed Nayun about the situation here through the transmission magic circle. After a moment, Nayun replied, saying that the relevant personnel and equipment could be prepared within five days.

The sky was completely dark, and two bright moons hung high in the night sky. The cold and white moonlight set off the entire St. Lawrence snow peak like a holy goddess.

Duan Tao and Naga stood on the highest rooftop of the castle, looking at the beautiful scenery in front of them, and couldn't help but be intoxicated.

"Junior brother, this place is so beautiful!" Naga snuggled in Duan Tao's arms and said intoxicatedly.

Duan Tao smiled and whispered in Naga's ear: "No matter how beautiful it is, it is not as charming as the senior sister!"

Naga raised Zhen's head and glared at Duan Tao with shame.

At this time, Yaqin, who was thousands of miles away, heard Duan Tao's words through the crystal necklace, and couldn't help but say sourly: "Hmph! This bad guy is lying to the girl again!" Before he finished speaking, an alarm sounded in his ears, "Be careful! The energy flow connection is wrong! The energy flow connection is wrong! Danger~!" Yaqin was startled and quickly disconnected the energy flow of the wrong link, and said in annoyance: "Hmph! It's all this bad brother!"

Early on the first morning, Duan Tao left Naga in the fortress, and he and Xiaopang entered the cave again.

After a while, Duan Tao and Xiaopang came to the stone gate that they passed yesterday. Duan Tao wiped off the moss at the position of his hand, and a touch screen-like device appeared in front of him. Duan Tao placed his right palm on the touch screen, and the mechanical sound that had appeared once again sounded again, "Sorry, your genetic characteristics do not match the database!" Duan Tao moved his palm away. Xiaopang blinked his big eyes and asked, "Boss, what's going on with that sound just now?" He looked around and said with a puzzled look: "It seems that there is no one?" Duan Tao smiled and said, "Of course there is no one! This is just a voice!" Xiaopang said suddenly: "I understand! It must be a memory crystal!" Duan Tao didn't know how to explain, so he nodded.

"Xiaopang, you have broken such a stone gate before! What is the scene inside?" Duan Tao asked.

Xiaopang stinged his forehead embarrassedly, "I don't remember!"

Duan Tao thought for a while and said to Xiaopang: "Xiaopang, do you know how to use fire magic?"

Xiaopang said: "I don't know how to magic! But my best thing is to use fire energy!"

Duan Tao nodded, "That's good! Xiaopang, you are ready to attack like the sea of ​​fire. Once I break through the stone gate and a foreign object gushes out, you will attack me!"

Xiaopang nodded, "I understand!" Then a pair of fat hands were placed on the chest, and a fireball about one meter in diameter appeared, containing amazing energy. Xiaopang glanced at Duan Tao.

Duan Tao turned his head and looked at the stone gate, took a few steps back, and suddenly put on the Dragon Soul Battle Armor. Duan Tao raised the Dragon Soul Sword and saw a fiery red energy gushing and spitting on the Dragon Soul Sword.

"Little fat, pay attention!"

Xiaopang nodded and stared at the stone gate tightly.

Duan Tao waved his sword to slash at the stone gate, and saw a half-moon-shaped fiery red sword aura flying straight towards the stone gate. With a loud bang, the stone gate shattered into countless pieces.

Xiaopang and Duan Tao immediately became nervous. However, nothing came out of it.

After waiting for a while, nothing came out. Duan Tao couldn't help but ask, "Little Pang, are there no bugs?"

"I don't know this, I don't know this!"

Duan Tao thought, ‘Maybe this secret room is different from the one Xiaopang has seen before!’ and said to Xiaopang: “Xiaopang, let’s go in and take a look!”

Xiaopang nodded and rushed in suddenly. Duan Tao didn't even have time to call him.

Duan Tao was worried that Xiaopang would make a mistake, so he hurriedly followed in. It was pitch black.

"Little fat!" Duan Tao shouted.

"I'm here!" Xiaopang's voice sounded not far ahead.

Duan Tao summoned a ball of fire, and a terrifying face immediately appeared not far in front of Duan Tao. Duan Tao was startled and subconsciously wanted to raise a knife to attack. However, the other party waved his hands and said anxiously: "Boss, it's me!" It turned out that the firelight twisted Xiaopang's face.

Duan Tao breathed a sigh of relief, then looked around the fireball in his hand, and saw many rectangular objects like coffins scattered around, arranged in an orderly manner. Each ten coffins were lined up in a row, connected to a metal object three meters high as a furnace through a hose connected to the top. There were four rows of such things here, two rows facing the stone door, and the other two rows were located on the walls on the left and right sides of the stone door. There was a device similar to a console in the middle of the secret room.

"Old, boss, is this a grave?" Xiaopang said in surprise.

Duan Tao frowned and said, "I'm afraid it's not that simple!"
