The material of the scroll is not good, but as an ordinary record carrier that does not have any power, the material does not matter.

And Sean was truly shocked when he saw what was recorded on this scroll.

This is an alchemy formula scroll.

A total of seventy-one alchemical formulas are recorded above.

The first seventy are all integrated alchemical formulas for ore purification and quenching, and the material ores recorded on them are not rare ores, even in today's era, these ores are all ores that can be found everywhere except for a dozen of them, which are relatively rare. However, even if it is a dozen or so rare ores, it is not impossible to buy, at least through the trading capital, it is still possible to buy it, but the amount cannot be too large.

The last formula is a blending formula: the seventy kinds of ores that have been purified and quenched before are finally combined and quenched into a new alloy.

This alloy, known as the "God Alloy", is the kind of "mecha" ore used by the Mecha Rage Bull and the Mecha Black Bee.

Sean already had an extremely profound understanding of its sturdiness, it was an alloy material that even the Black King had to chop several times in a row to be able to completely destroy!

However, what is really commendable is that this alloy is a material that can be made at present, seventy kinds of ores according to different proportions, the sum of about 1,000 kilograms can be purified into one kilogram, and if you make ordinary armor or pure iron weapons, three or four kilograms are enough. Even a heavily armed heavy armor weighs just over twenty kilograms.

If this recipe is applied to the army, the fourth-level army can directly become the sixth level, and the army above the seventh level and below the ninth level can also be upgraded by one level.

The value of this formula can be imagined.

With excitement and excitement in his eyes, Sean directly put the recipe into the storage ring, and then carefully inspected the stone cave. After confirming that there was nothing else, Sean's face didn't change much. He had already understood that for the mysterious mechanic, the value of this formula was the greatest, and nothing else was worth mentioning, so he let the most proud work under his command, the Crazy Bull, be in charge of guarding it.

Considering that there are two more passages. Sean didn't linger anymore, but turned around and left.

However, because the path he entered had been destroyed by the Mecha Raging Bull, it took a lot of effort for Sean to return to the hall.

After clearing two passages in succession and returning to this hall for the third time, Sean's mentality towards the statue in front of him became different. If it was just a curiosity before, now it is complete admiration, because this recipe has completely changed the embarrassing situation of insufficient foundation and insufficient combat power of the legion after the Void Duchy was transformed into an empire, and now as long as the materials are sufficient. All the fourth-level legions under his current command can be directly turned into sixth-level legions.

If the four legions, which are the main force, gain something in the war against the undead and are successfully promoted to the seventh-level legion, then the eighth-level legion can be directly born.

Four eighth-level legions, this is definitely a level only found in the old empire.

You must know that as the most powerful thousand-year alliance empire on the continent at present, there are only three eighth-level armies. And the St. Joels Empire, which has a ninth-level pure white winged knights, is only a ninth-level, and there is only a sixth-level army under it. If the Void Empire has four level 8 armies. Coupled with the almost innumerable sixth-level army, then let alone the Millennium Covenant Empire. Even if the Cinnas Empire and the Millennium Covenant Empire join forces to attack, the cost must be carefully estimated.

This is the true way to strength, and it belongs to the Void Empire!

How could Sean not admire the master of the mechanism in front of him who had created the formula of the god alloy?

As for the remaining two passages, Sean didn't care which one had the guard, anyway, one of them definitely was, so he wasn't in a hurry. I picked a random passage and just moved on.

Along the way, the enemies encountered are basically old models, which is not a threat at all to Sean, who has already killed the mecha mad bull. So Sean simply took it as if he was here to test his skills, after all, the sudden growth of the second heart made Sean a little unfamiliar with his own power control now. Just use these organ creatures to practice your hands, so that you can regain control and grasp of your body as soon as possible.

However, perhaps Sean's luck was not very good, and the path he picked at random did not have any news about the guards, but was a place similar to planting and saving. Sean guessed that this was probably a self-sufficient place for the Mechanic to live in the ruins of this cave, and that while the Mechanic was still alive, there would probably be some other servants or other creatures to help, but with the disappearance of these Mechanics, the place was completely deserted.

Finding nothing good, Sean stopped staying and walked towards the last passage.

While dealing with enemies and mastering his new powers and physical fit, Sean even had time to chat with the Black King once in a while.

It wasn't long before Sean came to the end of this last passage.

It's still a stone cave.

However, compared to the other caves that Sean had encountered before, this cave was more like a bathhouse, and the decoration also seemed to be a lot more careful, not as simple as other caves. But what really caught Sean's eye was a black stone placed on a platform in the middle of this cave.

The stone was no different from ordinary grains of sand, except for a dull sheen—not black, but more like a symbol of uncleanness and evil, as if invisible. It was suspended about ten centimeters away from the stone pillar in the middle, and with the size and decoration of this stone cave, it was impossible to see such a grain of sand anyway, but it was so unique that it attracted all the sights of Sean after entering the stone cave, so that Sean could not see anything else at all.

"Guard!" Sean, who had the experience that Gibriel had given Alexis, finally let out an exclamation at this time.

He didn't know who this guard was, but there was an unholy power exuding from it, and it was obvious that he should also be a ruthless person.

Unlike the method of extracting Nolo and Kokire, the experience of extracting Alexis has taught Sean many other ways to obtain guards, of which the Sacrifice of Power is the most famous. This is done in a way that only needs to be able to obtain the power remnants of a creature that has a soul mark in the wardship. Then you can get in touch with the guard system through this residual power, and directly return this power to its source and summon its existence.

Alexis had apparently fallen in some unknown place, but for Gybriel, who frequented the Void and the Outlands, it was not difficult to obtain some remnant of Alexis' power. And after Kibril obtained the remnants of this power, she couldn't understand the power of it, so she kept it. It wasn't until she came into contact with Sean that Gybril felt that this kind of thing would help Sean, so she passed it on to Sean.

It is precisely because of this that Sean also knows some unique situations that he has not yet figured out.

This made Sean know what it was when he saw this grain of sand for the first time.

"Dad, what's the guard?" The Black King asked.

"A powerful force." Sean thought about it and gave an explanation, but in order to avoid long nights and dreams, he quickly approached the stone pillar platform. Then he reached out and touched the black sand particles floating on the stone pillar.

As soon as the index finger of his right hand touched the black sand particle, the black sand particle immediately turned into a unique power of yin and evil and directly integrated into Sean's body. This force has a bit of coldness and darkness, and even a terrible aura of destruction, and Sean became a little stiff at the first time because of the impact of this force.

However, Sean, who had already absorbed Alexis' power once, knew very well that this power could not be used for long.

Really!

Just when Sean's thoughts fell, this power was inexplicably devoured and disappeared after entering Sean's body, and was replaced by a system prompt sound in Sean's mind that sounded directly.

[A special force has been detected.] 】

Data matching is in progress. 】

[Matched.] This force meets the criteria for Guardian System activation. 】

[The system is being tested.] 】

[After detection, the strength nature is 69% Chaos, 17% Void, and 14% Shadow.] The judging criteria are A-level, and there are a total of 37 people who meet the relevant data targets. 】

[Will you activate the guard lottery system?] 】

"Thirty-seven?" Sean was stunned for a moment, although he already knew that this power would activate the guard system and give birth to a guard, but after all, he had only been in contact with Alexis, so he still didn't know much about this system. After all, there weren't so many choices at that time, only Alexis was alone, and the evaluation of Alexis was S-level, and now I think that this A-level should be a low-level existence.

Sean guessed that it should be Nolo's strength stage. But he didn't have much to choose from anyway. So I had no choice but to agree.

[Detected that you have a guard enhancement effect, is the effect activated?] 】

Sean originally thought that the so-called guard enhancement should be to summon the guard and then give it another enhancement, which is probably to strengthen the lower sanctuary to the middle sanctuary, or the upper sanctuary to the legend. As a result, I didn't expect that the so-called guard reinforcement didn't mean this at all, which made Sean instantly have a new guess, and his breathing couldn't help but be much heavier.

[The guard enhancement effect has been activated, and the system is rejuvenating.] 】

[After the judgment is completed, the new standard is S-level, and there are three data targets that meet the nature of the relevant forces, do you start to select guards?] 】

Sean heard a new system beep, and he had basically figured out the situation.

Obviously, the power nature of this black sand grain is mainly based on the power of chaos, supplemented by the power of the void and shadow, so in the guard system, the guard who masters this type of power must also be selected as the target of the draw.

There were a total of thirty-seven A-level targets before, and the potential level was probably about the same as Nolo's state, and the powerhouses of the Sanctuary Realm might or may not have the opportunity to break through to the legend, which Sean had already asked from Nolo. However, in any case, the guards selected by the A-level standard are the lowest of the existence of the mid-level holy domain, and the birth level of the lower level of the holy domain is already a B-level qualification.

And the S-class, that's a stronger existence than the A-class!

If Sean is not mistaken, the lowest birth standard of the S-class is also the legendary powerhouse, and the upper limit of its strength is definitely the super strong class.

The reappearance of such a powerful helper would definitely be extremely beneficial to Sean and the entire Void Empire - at least, as long as Sean did not fall, these guards drawn out by Sean would never harm him, nor would they do anything harmful to the Void Empire.

The only thing that is uncontrollable at the moment is that I don't know which of the three people who meet the standards is more powerful.

But anyway, it's all random selection, and Sean doesn't care anymore, whoever can be drawn depends on luck, and he starts the lottery directly. (To be continued.) )
