The letter from the Duke of the Frontier lifted Roy's heart, which had just been relieved by the victory in the battle of the merger of the realms.

Marquis Herman, Second Prince of the Empire......

Will this kind of bigwigs in the upper echelons of the empire, if they really mean to be in the Blackstone Realm, because of Lord Denham's defeat?

I'm afraid not.

There must have been other ways to coerce Roy into giving up Blackstone Collar.

And this is something that Roy can't accept.

In this world, the status of a nobleman is very important, with many privileges, and it is extremely crucial for his own development.

Fortunately, Roy is not alone, behind him, or rather, behind the Blackstone Collar, there is still the Border Duke Soros family.

Judging from the contents of the letter, the Duke of the Frontier was already aware of the intentions of the Second Prince of the Empire and the Marquis of Herman to get their hands on the Blackstone Collar.

From a certain point of view, the reason why the second prince of the empire and the Marquis of Hermann made a twist and turn to let Lord Denham take action and launch a territory merger war against the Blackstone Territory was that they did not want to expose their intentions before obtaining the Blackstone Territory.

As long as the battle of territorial merger begins, under the sacred imperial law, even the border duke cannot forcibly intervene.

And now, the intentions of the Second Prince of the Empire and the Marquis of Herman have been exposed, and under the premise that the Duke of the Frontier is aware of it, it will not be so easy for them to make a move against the Black Stone Collar again.

Of course, one's own territory cannot be pinned on the hands of others, and only one's own strength can cope with all external crises.

This made Roy more and more eager to improve his strength and power.

The Bronze Horseman, in the end, is still too weak.

If he himself has the strength of a golden knight, if he has many bronze and even silver knights under his command, even if it is a high-ranking member of the empire, if he wants to move him, he has to weigh whether it is worth it.

……

Putting away the duke's letters, Roy prepared to search the lord's study.

For a nobleman, there is no more important place than a treasure vault and a study.

Needless to say, the treasure trove, and the study ...... In this era, knowledge is a very cherished resource, and the study room where knowledge books are placed is undoubtedly the embodiment of the heritage of an aristocratic family.

After a careful search, Roy finally had two of the most valuable things in front of him.

It's the same, it's a breathing book.

On the other hand, it was an envelope with a gilded edge and a violet emblem.

The secret book of the breathing method, called "Liujin Breathing Method", is an advanced breathing method that focuses on defense, and at the same time records a secret technique called "Instant Gold" used in conjunction with the breathing method, which can be used within 10 seconds after use, and the fighting qi will flow backwards into the heart, bringing stronger explosive power, but the shortcomings are also obvious, after the duration of the secret technique is over, the heart will be hit hard, and you can't do it with people for at least three months, otherwise it will further aggravate the trauma of the heart, and it can't be used in a non-life and death situation.

Compared with the "Burst Flame Breathing Method", although the name of "Liujin Breathing Method" is better, the effect is obviously inferior.

Not to mention the speed of ingestion of magic particles in his daily practice, just the fact that his focus was on the defense that was useless in Roy's opinion, and the secret technique of the breathing method with great side effects, made him look down on this advanced breathing method.

Although it is also an advanced breathing method, as a subordinate version of a special breathing method, the effect of the explosive breathing method is not comparable to that of ordinary advanced breathing methods.

The "Ryukin Breath" is of lower quality, but it is not useless, and it can be used to reward his official knights with a chance to break through the bronze rank.

At the beginning of spring next year, the border side needs to send two bronze knights to cooperate in defense, and now in the blackstone territory, the bronze level combat power is obviously insufficient. - Lord Denham and his attendant knight Jax, who were imprisoned in Blackstone Prison, could not be released, so naturally they could not be counted in their own combat power.

Therefore, it is urgent to train several new Bronze Horsemen.

Putting the "Ryukin Breathing Method" into the storage space of the [Original Sin Cube], Roy set his eyes on the envelope with the violet emblem.

The time he has been in this world has not been short, and Roy has also learned some conventional knowledge through the books in the study of the old lord of the Black Stone Leader.

The violet emblem is a symbol of the royal family of the Glow Empire.

Dare to use this emblem, think about it, this letter should be sent by the second prince of the empire to Lord Denham.

Roy's heart struck.

Through this letter, he may be able to know more clearly the real reason why the second prince of the empire targeted the black stone collar.

Picking up the envelope and opening it halfway through, Roy suddenly felt the envelope in his hand start to heat up.

His face changed, he turned decisively, and threw the envelope in his hand through the open window.

As soon as the envelope was thrown, it exploded into a ball of blooming fire the size of a water tank.

The huge movement immediately attracted the attention of the entire Iron Mountain Fortress.

The footsteps of "stamping" approached rapidly, and the door of the study was pushed open violently, making a loud "bang", and Red rushed in with an anxious face, until he saw Roy intact, and then he breathed a sigh of relief: "Lord Roy, what happened, but someone attacked you?" ”

Roy shook his head, his face a little ugly.

At this moment, the edge of the window had been scorched black by the flames from the explosion, and the solid rock, not to mention the flesh and blood of the human body.

This letter from the second prince of the empire actually has the function of "automatic identification", once an outsider tries to open it without permission, it will cause an explosion, and the power of the explosion is extremely powerful, at close range, even if it is a silver knight, the head will be seriously injured.

Looking at the blackened window, Roy's fear of the second prince of the empire rose to a higher level.

Just a letter, to do such precautions, it can be seen that the person is thoughtful, such a person is by no means easy to deal with.

"Hoo ......"

Exhaling lightly, suppressing the thoughts in his heart, Roy looked at Red: "Uncle Red, how is the reception handled?" ”

"Almost." After making sure that Roy was okay, Red was relieved, and he nodded: "The main forces of the Iron Mountain Territory have all been detained in the Blackstone Prison, and there are only two or three official knights left behind, and there are quite a few probationary knights, but there is no need to worry, and now they have all been unloaded and imprisoned with weapons and armor." ”

"As for the people of the Iron Mountain Territory...... They showed no sign of resistance, and some of them seemed very happy. ”

At the end, Red's face was a little strange.

The performance of the people reflects how unpopular Lord Denham is.

"By the way, Lord Roy, in the process of receiving it, we found Lord Denham's treasure trove."

"Oh?"

Roy's eyes moved slightly.

The fact that the Iron Mountain Collar can afford to raise so many official knights shows its wealth, and there must be a lot of good things in its treasure trove, right?
