Looking at Du Long riding on the big lion with a faint gaze, he continued to borrow strength on the cliff, and disappeared into the darkness above the cliff in a few ups and downs, Old Man Du was silent for a long time, and then said solemnly: "Old horse!"

"The subordinates are here!" replied in a deep voice from the old horse, who had not spoken.

"You should quickly send someone to thoroughly investigate whether there is a problem with Du Zhennan's origin! Also, pass on my secret order to draw a team of reliable officers from the Zhongwu Legion, and at least one of them must have a master whose strength has reached the Gangdan rank to Fengli County to report to Long'er!" Old Man Du explained solemnly.

"Yes, my subordinates will handle this matter!" The old horse didn't talk nonsense, and immediately turned around after receiving the order, followed Du Long, and shot towards the top of the cliff.

As the old horse disappeared above the dark cliff, Old Man Du retracted his gaze, turned around and resolutely walked towards the inside of the cave!

In the dark, Du Long rode on Xiao Lie and rushed all the way towards the capital, and soon rushed back to Du Mansion and went straight to his grandfather's special study.

Outside the door of the study, two guards looked at Du Long who was approaching vigilantly, and one of them said in a deep voice: "Young Master Du Long!

Riding on Xiao Lie, Du Long was not embarrassed by these subordinates who were loyal to his grandfather, and when he turned his hand, a letter representing Old Man Du appeared in the palm of his hand.

"This is the letter that my grandfather handed me by himself, I want to go in and check some information!" Du Long explained loudly.

After one of the guards stepped forward to confirm that the letter was correct, he immediately saluted respectfully: "The letter is confirmed! Young Master Du Long can enter the study at will!"

Nodding with a smile on his face, Du Long jumped off the big lion, left it outside the door of the study, and pushed the door alone to enter the place where the symbol of the supreme power of the Du Mansion was located!

In the study, Du Long is not the first time to enter this room, but every time he wants to come in in the past, he has to be led by his grandfather himself, and it is the first time to come in alone like today!

Familiar with the bookshelves that his grandfather had mentioned, he quickly found a war report from more than 20 years ago, took it down, and began to sit at his desk and began to read it by candlelight.

A detailed battle report from more than 20 years ago is like a movie, and the scenes are presented in Du Long's mind!

Between the Blue Moon Empire and the Haotian Empire, the northwest starts from the Red Dragon Gorge and ends at the customs in the southeast, both of which belong to the dangerous passes that are difficult to defend and attack, only in the middle is a relatively flat area hundreds of miles wide!

There is a strong city called Haoyue City on the side of this area near the Blue Moon Empire, and there is also a strong city called Yulin Pass near the Haotian Empire, also known as Yulin City!

The area of hundreds of miles between these two cities is where the two empires are still disputed, and both empires claim sovereignty over the region!

As a result, in this area, there is often a certain degree of conflict, and the confrontation between the two empires is formed between Haoyue City and Yulin City, and there will be countless large and small conflicts every year!

More than twenty years ago, the army of the Blue Moon Empire invaded this land again, and the Haotian Empire, as in previous years, sent a large army to stop the invasion of the Blue Moon Empire!

In this battle, the Haotian Empire was not well prepared, although it had already received information about the number of enemy troops, but it never thought that the number of masters inside the opponent was obviously more than double that of the past!

After suffering a big loss, the army of the Haotian Empire could only temporarily retreat to Yulin Pass and began to ask for support from home, so the reserve army Zhenwei Legion stationed in the northwest direction of Yulin Pass received an order!

They began to march to the southeast, preparing to aid the defenders of Yulin Pass, but they never thought that they encountered the enemy's robbery on the way, and the enemy army actually directly dispatched the spirit level masters, and successfully killed Du Fengyun, the commander of the Zhenwei Legion, and several of his subordinates who were loyal to the lord's lieutenants!

Subsequently, the Haotian Empire also passively sent Fan Kun, a master of spiritual strength, to launch a surprise attack on the enemy army, killing several enemy generals and deputy generals in retaliation!

It seemed to be frightened by the reaction of the Haotian Empire, and the Blue Moon Empire began to gradually withdraw from the battle, so a big war gradually subsided, and it did not evolve into a real fight between the two countries!

Du Long slowly closed the battle report and began to close his eyes and meditate!

'The army of the Blue Moon Empire was menacing at the beginning, on the surface, it seemed that it was because it was frightened away by the Spirit Rank masters dispatched by the Haotian Empire, but in fact, it felt a little wrong!' Du Long thought secretly in his heart.

"Hehe-hee, don't you understand this? Isn't it a waste of time if someone achieves their goal and successfully conceals their true purpose, and doesn't retreat?"

"The goal has been achieved?!Could it be that the goal of launching such a large-scale battle is just to kill Uncle Tang?!" Du Long suddenly realized.

"Nonsense! There is a dangerous pass through the sea in the southeast of the Haotian Empire, and a dangerous pass in the northwest of the Red Dragon Gorge! The two sides are looking at the Yulin Pass in the middle, even if the Blue Moon Empire can conquer the Yulin Pass, it will have to worry about being attacked by the other two sides and cut off the back road! If they lose the logistics and supplies, they may have no return!" The Ring Spirit Beauty snorted disdainfully.

"Since they don't dare to attack Yulin Pass head-on, and launch such a huge battle, it will definitely not be a bluff, there must be their goal behind it! Now it seems that the Blue Moon Empire's target is the Zhenwei Legion, and they want to replace the Zhenwei Legion! and then flank the Red Dragon Gorge under our control back and forth!" Du Long woke up.

"That's right! The son can be taught!" The spirit girl shook her head and continued to analyze cutely: "However, now it seems that even the Li family's Dunwu Legion has been controlled, you must know that the Dunwu Legion is the reserve legion of the Yulin Pass defenders! If they come from behind, and then cooperate with the Red Dragon Gorge to be taken, alas, the entire Haotian Empire is in danger!"

"Hmph! This Blue Moon Empire is really ambitious! It has actually been laid out for decades!" Du Long snorted angrily.

"According to the information I have gathered, forty or fifty years ago, that old guy of the Fan family did not break through to reach the strength of the spirit level! Later, his strength broke through, and he succeeded in obtaining the position of the left minister of the empire through his merits again and again, and now, he is even more powerful!"

"It seems that when I was deceived back then, the Du clan was raided, which is equivalent to indirectly helping those guys to control the military power in the hands of the Du clan in advance! Without spending a single soldier, they can successfully control the Chilong Gorge and the dangerous pass! Now, they can't have the same good opportunity as back then!" Du Long muttered to himself with a faint look in his eyes: "No! These guys can't be allowed to succeed this time! We have to step up the construction of territorial forces!"

"Cut! With the soft and hard power in your hands, it is almost impossible to develop the strength that can influence the overall situation before the crisis breaks out!"

"Could it be that there is really no way at all?!" Du Long replied unwillingly.

"Hehe, you can't rely on your stupid brain! However, with Aunt Ben's wise head, everything is impossible and possible!" said the Ring Spirit Beauty proudly.

Du Long's eyes lit up, and he hurriedly asked, "Ling'er!

"Nonsense! Don't look at how advanced the world Grandma Ben came from, dealing with this most primitive cold weapon war, that's not a piece of cake?!"

"That'...... What am I going to do to help Grandpa and them?!"

"It's very simple! Next, no matter what, you have to fully cooperate with Aunt Ben's arrangement! Remember, there is no mistrust!"

"Cooperate, I will fully cooperate with any arrangements made by Ling'er's beauty! Can you tell me more about what preparations we have to make now?!"

"You have already warned your shrewd grandfather, he will definitely send someone to investigate Du Zhennan's true origin in detail, even if you can't find out his true origin, it shouldn't be difficult to find out if he is the Du family's bloodline!

"As for you...... Fengli County still has to go, and the arsenal must also be built quickly! In addition, your cavalry army must also be established as soon as possible, as for how to build it, hehe! Due to the limited time and limited funds! With limited resources in all aspects, we can only build a powerful army beyond imagination that can be armed to the teeth!"

"Oh, but there's a detailed plan for me to hear!" Du Long asked curiously.

"Well...... It's a secret for the time being, but you'll know it when the time comes!In short, it's going to be an eye-opener for you!" The Ringspirit Beauty replied with a mysterious smile.
