The green holographic screen disappeared with a silence. Chen Zhen walked to Mihawk, stared at the treasure box, rubbed his hands and drooled: "Mihawk, help me open it!"

"As for orders, Lord Lord!" Mihawk waved the steel scepter, broke the lock on the box, and gently pulled it with his hand to open the box.

Chen Zhen rushed over and looked carefully, but found that there was no treasure in the treasure box.

It was just a letter, lying quietly on a pile of gold coins.

Chen Zhen stretched out his hand and clewed out the letter paper. After receiving the letter paper, the green holographic screen actually appeared with a sound. The small cursor couldn't help but typed a line of small words:

[Congratulations to Lord Lord for completing today's must-choose quest! You have received a reward of 50 worship values ​​and 100 gold coins!]

Chen Zhen thought to himself: Where are the gold coins?

【It's in the box!】

Chen Zhen: Your mission system is really itchy for you...

【I am very happy to be sneered.】

After typing this sentence, the small cursor and the green screen both disappeared.

Chen Zhen was completely drunk. He was actually slapped by the mission system. The Skeleton King's mission said that the extra treasure chest reward was given, but the box contained the extra gold coin reward for the letterhead mission. He was so good at calculating!

Chen Zhen now just hopes that the mysterious store system will not be as tricky as the task system.

The Lord is not in the mood to pay attention to the mission system's cheating. He has to take a good look at what the letter in his hand wrote.

He took out the old envelope and took out the yellowed letter paper inside, which had very short lines of small words written on it:

"Great Lord Lord, recently, visions of the Despair Plain have frequently appeared and monsters are raging. I believe you have many doubts and unsolved mysteries. If you are interested, please come to the ancient tower in the southeast to find me. I am willing to do my best to answer one or two of you..."

After reading the letter, Chen Zhen stretched out his finger to pick the envelope, and it really took out something - there was a key hidden in the envelope.

It seems that this key should be used to open the ancient tower gate. Chen Zhen carefully put away the key, then frowned and began to ponder.

"Well..." He thought for a long time, but he didn't think of it, so he waved his hand and said, "Okay, go home!"

...

The lord took the lead and climbed out of the deep pit along the rope and left the bunker. When they passed the quarrying resource station, they found that 12 leaders were already busy here. The cavalry captain stopped and said to Joan of Arc: "Miss Joan of Arc, we will not go back to the castle..."

"This resource station needs soldiers to guard it. After all, no one can guarantee whether there will be skeleton people."

Joan of Arc knew that the cavalry captain didn't want to go back to the castle and said so, so he didn't say much, just nodded silently to agree.

But Joan of Arc decided to go back to the castle with the Lord. If she stayed at the resource station, it would not be so appropriate.

Miss Joan of Arc is actually a very upright person and cares about other people's evaluations, otherwise she would not have made such a decision. The old cavalry knew Joan of Arc very well and shook her head and sighed. Just after they separated, they would inevitably feel a little reluctant to leave.

...

After returning to the castle, it was already the fifteenth night. Chen Zhen saw that several houses and several rye fields had been built outside the castle.

The chief assistant Haska also specially built a stable. When he heard that the cavalry would not come back, he was so angry that he blew his beard and said, "I'm really in vain!"

"Don't be angry, Lao Ha, they will be back sooner or later!" Chen Zhen said to Haska with a smile: "Do you know Lao Ha, the castle can be upgraded to level 1 and level 4! I can't wait to see what level 4 castle looks like!"

Haska was very puzzled. It was only a few days since the level 3 castle was upgraded, but it had been upgraded again.

"Lord, have you calculated it wrong?" Haska couldn't help but wonder.

"What is wrong? What is wrong? I don't know?" Chen Zhen was also puzzled.

Haska knew that asking Lord Lord such a question was useless. If he really calculated it wrong, the castle would not be upgraded. I wait and see, so he nodded and said, "Then please let Lord Lord Lord start upgrading the castle."

Chen Zhen thought to himself: Up to the level of the horse!

The castle indeed trembled, and the walls continued to expand into the four outer circles, increasing the radius of the castle wall by nine meters.

The Council Hall also grew taller. The third-level stone steps under its feet turned into fourth-level stone steps. There was also a small stone house. Haska noticed the stone house, but he was as knowledgeable as him, and he didn't know what the stone house was for.

Several messages appeared in Chen Zhen’s mind:

(The castle is upgraded to level 1 and level 4!)

(The daily number of crucible alchemy is 4 pieces)

(The maximum limit for occupants has been increased to 90)

(Please arrange for the castle of the extra-staff leader Minto as soon as possible)

...

(The castle mysterious store system is open. If you want to know more, please enter the stone house next to the council hall, which is the mysterious store)

Chen Zhen said "Oh..." and walked towards the stone house. He was about to get in when Haska suddenly said behind him: "Lord, please don't enter rashly! No one can be sure what the stone house is for..."

Chen Zhen did not stop and said, "You'll know if you go in and take a look!"

As soon as Chen Zhen entered the stone house, he found a lighter on his body. He quickly touched his body. After touching it, he sat on the ground and cried loudly: "It's simply a robbery..."

Hearing the cry of the lord, Haska rushed over and entered the stone house.

As soon as he entered the stone house, he became petrified, because a lot of information suddenly poured into his mind. These information appeared out of thin air, flashing and making Haska understand its function immediately...

"Mysterious Store..." Haska murmured: "It's simply unheard of."

The rules of the mysterious store are very simple. Anyone who enters it (except Lord Lord) can choose the goods he wants to buy through the information in his mind. After confirming the purchase, the gold coins he carries will be automatically confiscated by the stone house and become the property of Lord Lord Lord Lord.

To put it bluntly, this mysterious store is for the Lord to make money.

A treasure came into Haska's mind: Intelligence cloak - after wearing it, intelligence will increase by 10%, and price will increase by 150 gold coins.

Apart from this treasure, there is no information about other treasures.

The Lord was still crying. Haska didn't understand what he was crying. Only Chen Zhen and Shiwu knew that when Chen Zhen came in, Shiwu directly took away the Lord's 100 gold coins of start-up funds and used them for the goods.
