This treasure that belongs to Tang Mu is a treasure that can grow, as long as there is enough luck value, it can grow almost infinitely, but the luck value is not so good, if you want to get the luck value, there is no other way, only by using this treasure to summon the treasures of the heavens and the space-time world can you get the luck value.

Therefore, although this treasure theoretically speaking, as long as he has enough Qi Luck Value, he can immediately upgrade to a very high level and become a very powerful treasure, but due to the current Qi Luck Value, even if Tang Mu wants to upgrade it to a very high level immediately, it is impossible.

And according to Tang Mu's knowledge of the information of this treasure itself, this Heavenly Summoning Treasure Book, with the upgrade, can not only summon all kinds of treasures of the heavens, but even upgrade to a certain level, even life can be summoned, it is definitely a direct treasure against the sky.

Of course, this Heavenly Summoning Treasure Book is very rebellious, but it is not infinitely able to summon, and using the Heavenly Summoning Book to summon treasures has its own unique limitations.

The number of summons and the level of the treasures that can be summoned are all limited by the level of the treasure itself, otherwise, with this Heavenly Summoning Treasure Book, it would not be delusional for Tang Mu to dominate the entire world in minutes.

When the Heavenly Summoning Book is at the first level, each of them can only have one summoning opportunity, and this time the summoning opportunity has been used by Tang Mu, and if you want to continue summoning, you can only wait for the next month, or the treasure can be upgraded.

The summoning methods of the Heavenly Summoning Book can generally be divided into four types:

Ordinary summoning: This kind of summoning can only summon treasures that do not exceed the level of the Heavenly Summoning Treasure Book itself, and the summon that Tang Mu used just now was an ordinary summon.

Random summoning: There is no limit to the level of summoned treasures, it depends entirely on luck, but this kind of summoning needs to consume a certain amount of luck, the more luck is consumed, the higher the probability of summoning a treasure of higher level.

Designated summoning: Specify the treasure that needs to be summoned, or the living being, generally such a summon is limited by the summoner's life level, and the summoning needs to consume qi luck value, the more qi luck value consumed, the higher the probability of being able to summon the treasure in mind.

Skip the level of summoning: The summoner himself consumes his own energy to summon, and the treasures summoned cannot exceed the summoner's own level three levels.

"It's a pity!"

Tang Mu thought with some regret in his heart, because this treasure had just opened, everything was blank, and he could only summon normally, otherwise if he had qi luck value and consumed qi luck value to summon, the treasure he might summon would be much better than the treasure summoned now.

"But this time, the treasures that are normally summoned are not bad."

Tang Mu identified the two summoned treasures, and he was still very excited in his heart.

The treasure of the Heavenly Summoning Treasure Book has just become Tang Mu's companion natal magic weapon, and it has not been long since it was formed, in addition to the summoning ability, it also comes with a one-cubic meter strange space, and every time the treasure summoned is basically put into this strange space first.

In addition to this strange space accident, the treasures summoned by the heavens also have their own function of identifying treasures, which is not unexpected by Tang Mu, if they can't have the function of identifying treasures, if they don't know the summoned treasures and don't know their value, then it will definitely be a tragedy.

However, there are also restrictions on the identification of treasures in this Heavenly Summoning Treasure Book, and generally the treasures that are identified for free cannot exceed the level of the treasure of the Heavenly Summoning Treasure Book, otherwise the appraisal will cost other costs.

And once the treasure exceeds the level of the Heavenly Summoning Treasure Book itself, if you want to identify it, you need to consume Qi Luck value, and the higher the level of the treasure exceeds the Heavenly Summoning Treasure Book, the more Qi Luck value will be spent on identification.

Generally, a large level of treasure that exceeds the level of the treasure of the Heavenly Summoning Treasure Book requires an additional ten points of luck for identification, and more than two large levels, it costs an additional one hundred points of luck for identification.

The higher the level of the treasure, the more Qi Luck value is spent on identification, and for each large level exceeded, the Qi Luck value spent on identification increases tenfold.

Although the identification of the Heavenly Summoning Book has a limit on the value of luck, for Tang Mu, it is definitely an amazing function, you must know that even a person with great knowledge cannot know the role of all items.

However, the existence of the treasures summoned by the heavens made Tang Mu as long as his luck was enough, and there were no treasures that he couldn't figure out.

"It's a pity, everything is worth luck."

Due to the limitation of qi luck value, Tang Mu can only identify first-level treasures and second-level treasures at most, and the number of second-level treasures that can be identified can only be seven, and he will not be able to identify any more, as for the treasures above the second level, if you want to identify them, you don't have the ability to identify them.

"I want to identify the effect of the treasure I have summoned, then my sword, then the bead in Fei Ling's hand, and finally, if possible, identify the things I prepared before the end of this time, and see how many things have mutated in this last world."

Thinking of this, Tang Mu opened the box he had just taken out, and suddenly rows of orange crystals in the box appeared in front of Tang Mu and Chu Feiling's eyes.

"This is what you summoned, it's a crystal, it's such a beautiful crystal!"

Chu Feiling saw these orange crystals, and said happily, no woman can resist a beautiful attack, these beautiful orange crystals, for women, are absolutely irresistible temptation.

"Let's identify first!"

After speaking, Tang Mu held the Heavenly Summoning Treasure Book in his hand, and then his heart moved, and he saw a light shooting out from the Heavenly Summoning Treasure Book shining on these crystals, and then the Heavenly Summoning Treasure Book showed the effect of these orange crystals, and transmitted this information to Tang Mu's mind.

Second-level energy crystal stone: first-level medium-grade treasure, special energy, function one, can absorb the energy in it with special exercises, improve the cultivation of life, role two: can be used as an energy source for the operation of scientific and technological items, or used to arrange formations.

The function is very simple, but for Tang Mu now, it has no effect for the time being, just because now Tang Mu has neither the cultivation method, nor the scientific and technological items that need the energy crystal stone to operate, as for the arrangement of the formation, he will not be able to.

Speaking of which, although Tang Mu obtained the memories of Tang Mu the Traverser and Tang Mu the Reborn, except for the treasures brought by these two Tang Mu, most of the memories of these two Tang Mu were useless to Tang Mu.

Don't talk about the traverser, Tang Mu was an ordinary person before the crossing, and his memory made Tang Mu have more knowledge of another world at most, and there really wasn't much of an extraordinary memory.

And although the world where the reborn Tang Mu is located is likely to be the most similar to Tang Mu's world, and even the history is similar, the future development may be the same, and even after the end of the world, that world has become an extraordinary world.

But from the memories of the reborn Tang Mu, Tang Mu knew that the world of the reborn Tang Mu was still very different from his world.
