Half a month passed slowly, and during this period of time, everything began to go on the right track.

The training of the Knights of the Round Table, Rex will go every day, and the training things Rex does it by himself, like this kind of thing, you must do it yourself, and one of the most taboo things in the army is that the soldiers don't know the superior's storage, like training the new army, not personally mastering it, and telling the subordinates to do it, when the new army training is successful, who will listen to it in the end.

For example, in the last years of the Manchu Qing Dynasty, the new army of the six towns of Beiyang was trained, and the cost was quite large, and the price paid was not small, but in the end, it became someone else's private army, such a mistake Rex would not be.

After returning from the training base of the Knights of the Round Table today, Rex can't wait to enter the Warcraft system, and today the mysterious treasure room has been successfully built, and Rex has refreshed the three grid treasures that appear in the mysterious treasure room? There's already a sense of impatience.

After a long journey, Rex looked at a building not far from the town hall, four steel pillars were embedded in the dirt, and the four chains tightly locked a square box, the box had a blue pattern on it, it looked like a magic book, but this box was more weird, it was floating, and it did not fall down because of the chains, three azure magic crystals were constantly flying around the building, circle after circle.

Rex walked forward quickly and began to check directly, the appearance of the mysterious treasure room, Rex did not have the slightest sense of appreciation.

A hazy light appeared in front of Rex, like a light curtain, and the treasures of the three grids of the mysterious treasure room bloomed in front of Rex.

This is a red heavy book, the book is dazzling, attracting Rex's mind, and his mind begins to recall, the memories of the past are like watching a blockbuster movie, and the information about the red heavy book slowly flows through his mind.

【Book of Energy; Raise your heroes by one rank. Concentrate; Cannot be used to upgrade to Hero Rank. 】

Reaching out and grabbing the heavy book of energy, a hint appeared in front of Rex, 1000 gold coins, Rex did not hesitate at all, and took it directly, the recharged 5000 gold coins, in addition to recruiting 200 infantry heroes, it didn't cost much, 200 infantry heroes were only 2000 gold coins, the cost of establishing this mysterious treasure room was not very large, the book of energy in front of him, not to mention 1000 gold coins, even if it was 10000 gold coins, Rex had to take it.

Because the effect of this Book of Energy is really against the sky, in the game it is to increase by 1 level, here it is to raise a level, Rex now has the strength of the eighth order, and after using the Book of Energy, it can be promoted to the ninth order of Cheng Dù.

Stormwind and his party, while seeing Arthas, felt the moment of Gilness's fate, Arthas also brought a lot of pressure to Rex, Arthas is only 19 years old this year, much older than Rex, but his strength is already a ninth-order paladin, and he looks like an incomparably perfect character, standing with Arthas, a strong contrast with Rex's incompetence.

The heavy book of energy was held in his hand, Rex showed a satisfied smile, the power of this Warcraft system can be seen here, Rex did not use it immediately, his body here is just consciousness, or wait until he returns to the real world, gently and continuously stroking the book of energy, Rex is like stroking **, and continues to look at the remaining two treasures.

[Small purification potion; Restores a small amount of mana in 30 seconds. Concentrate; Cannot be used in battle. 】

A bottle of crystal clear green ** power potion, exuding a hazy green light, for this small purification potion, Rex did not buy, this bottle will cost 70 gold coins, up to five bottles, 350 gold coins, although Rex does not lack this gold coin, but he does not plan to spend this unjust money, if it can be used in battle, the value of the small purification potion is undoubtedly very high, but when it is used in non-combat, his value begins to depreciate, in the world of Azeroth, mages have a lot of means to restore magic power, This little purification potion is not very surprising, because there are so many ways to restore mana in a non-combat state.

【Return to the City Scroll; Teleport the user to the bound city, Note; There must be an order in the bound city,]

The remaining two items, if compared with the Book of Energy, are undoubtedly much less valuable, if the Book of Energy is sold, it is absolutely sky-high, using the Book of Energy can not become a hero-level powerhouse, but it can make the strength of the eighth order become the ninth order, similar to Rex, the price of a return scroll is 350 gold coins, Rex bought all five return scrolls, which is another 1750 gold coins spent, all added together, just to buy the treasures of the mysterious treasure room, Rex spent the remaining gold coins, and the 5,000 gold coins he recharged, there was not much left, it was already a single digit left.

When the five return scrolls appeared in his hand, there were five amulets, which were about the size of a palm compared to the thin return scrolls, and they were made of wood, which looked like a handicraft.

The use of the return scroll should be combined with this order, which is very user-friendly, and it can not only be bound in one place.

Rex smiled brightly, this time he went to Dalaran and had something to sell, and that was the scroll of returning to the city.

Exiting from the Warcraft system, slowly breaking open his eyes, Rex began to communicate, with the gentle stroking of the bright red birthmark, Rex felt the treasure he bought out of thin air, accompanied by one of his own thoughts, a heavy book of energy appeared in Rex's hand, looked at the book of energy, and found that the book of energy and the Warcraft system, there is no difference, Rex directly chose to use, the method of use is very simple, that is, tear and shred.

With Rex's pulling, the book of energy was torn apart very lightly, it was like tearing a thin piece of paper, and the heavy book of energy in his hand began to turn into a little light, and began to hover and fly in front of Rex, and in the last moment, it all flew towards Rex, and finally merged into Rex's body.
