Sure enough, as Yan ruthlessly expected, Gonggong Hong only said a few threatening words, and the guard actually knelt down and begged for mercy!

Immediately, the gate of this Maple Leaf City was opened! Directly let Yan Ruthless's 200,000 army enter!

Yan Wuru didn't expect that this time it would be so smooth, and he would be able to win a city just by moving his mouth!

And just when Yan ruthlessly took down this Maple Leaf City, Empress Dowager Yan, who was far away in the ancient Zhao Kingdom, finally got the news!

In the palace of the ancient Zhao Kingdom!

Empress Dowager Yan is frowning at the letter from the Yuan Kingdom! This letter was addressed to the Empress Dowager Yan by the emperor of the ancient Zhao State today, that is, the younger brother of the eldest princess of the Yuan Kingdom!

On this letter, it is written that Yan Guo is attacking Yuan State on a large scale, and there are two very powerful warriors in Yan State's army! Therefore, the Emperor of Yuan State wrote to Gu Zhao Guo to help them kill those two warriors!

But Empress Dowager Yan didn't know that these two warriors were Yan Ruthless and King Yao!

And at this moment, an old eunuch who was over half a hundred years old outside the Empress Dowager Yan's bedroom said: "Eldest princess, patriarch of the Jiuli clan, Chi Min asks to see!"

"Xuan!" Empress Dowager Yan said impatiently!

"The patriarch of the Xuanjiuli clan is here!" the old eunuch shouted!

Immediately, a middle-aged man appeared!

This man was of medium height, on the left and right, wearing a pair of blue cloth slacks, with a wide cowhide belt tied around his waist; his upper body was bare, and his muscles were well developed, protruding ridges on his shoulders and arms; on his shoulders were covered with a few red marks of thick hemp rope, which enhanced his strong spirit; he had no hair, and his hair was thick and black; on his round face, under his broad thick eyebrows, a pair of shrewd, deep eyes flashed; especially when he smiled, a mouth full of white teeth was exposed, which was very striking.

"Master, I haven't seen you for many years, Chi Min is polite!"

"Yes, I haven't seen him for many years!The Patriarch should have had a very nourishing life these years!" Empress Dowager Yan pointed to this Chi Min with her eyes, and said in a cold tone!

"Hehe, the master laughed! Over the years, for the unity of the ancient Zhao country, I dare not slack off day and night, and I hope the master will see it!"

"Patriarch, are you blind to me? For so many years, you have been in the Green Bone Sect to be windy and rainy, even if you are a barbarian sect leader, you dare not say that you can be your enemy! These things, do you really want me to be blind!" Empress Dowager Yan suddenly burst out of anger, slammed the table, and roared angrily at this Chi Min!

"Princess! I have no two hearts! Everything I do is for you, master!" Seeing that Empress Dowager Yan was angry, Chi Min quickly knelt down in fright!

"Hmph, Chi Min, I will let you go this time, if there is a next time, I will let your Jiuli clan completely disappear from this Hongyun Continent!"

"Yes!yes!yes!"

"Okay, let's talk, come to me this time, what's the matter. Empress Dowager Yan asked!

"Back to the master! I heard that there are ten cities in my ancient Zhao country that have been occupied by the Yan country! And according to reliable sources, the people who occupy the cities have the shadow of the Xuanyuan clan, I want to go there and see if they are from the Xuanyuan clan!"

Seeing that Chi Min was doing this, Empress Dowager Yan shook her head helplessly and said, "Don't go to see it, it's really the Xuanyuan clan!"

"The Xuanyuan Clan has also come out! Master, the Xuanyuan Clan must have taken refuge in the Yan Kingdom! This Yan Kingdom has obtained the Xuanyuan Clan, this is our henchmen! Master, I ask to lead troops to eliminate the Xuanyuan Clan!"

"No! The Xuanyuan Clan is not worried! Now the patriarch of the Xuanyuan Clan is a yellow-haired junior, and the Xuanyuan Fat Heavenly Soldiers have not defected to the Yan Kingdom with the Xuanyuan Clan! Now as long as the Xuanyuan Clan does not have Xuanyuan Fat Heaven, the others are nothing! No matter if you have other tasks now!" Empress Dowager Yan said!

"Another mission?" Chi Min muttered with a frown!

"I asked you to go to the Yuan Kingdom, recently the Yan Kingdom is attacking the Yuan Kingdom on a large scale, and the Yan Kingdom seems to have sent two masters, you go and see, what kind of characters those two masters are! If you can, take the heads of the two of them back to see me!"

"Yes!" nodded solemnly!

"It's okay, you can step aside!" Empress Dowager Yan waved her hand at Chi Min!

Immediately, the Chi Min left in an instant!

It is estimated that Yan Ruthless did not find out that he was about to have a big danger!

At this time, Yan is ruthless, and he is immersed in the joy of breaking through!

Yan Wuru has basically researched the shortest route to directly attack the Imperial City of the Yuan Kingdom! and can kill all the way through without any obstacles!

But the ideal is beautiful, but the reality is cruel, just when Yan ruthlessly prepared to take the third city in one go, he encountered a big trouble!

The third city is called Iron Tree City!

The reason why this city is called Iron Tree City is not because there is an iron tree in this city!

Therefore, no matter how windy or rainy, the walls of this Iron Tree City will not rust! As for why the Yuan Kingdom would build such a city, it is mainly because the Yuan Kingdom had a prince a hundred years ago, and he didn't like other things in his life, so he liked iron!

This Iron Tree City is the fief of the prince! The prince directly watered all the walls of this city with molten iron, even the houses in the city! Everything is iron!

However, it also cost the prince all his possessions, and in the end, all the walls of this Iron Tree City are iron, but half of the houses in the city are iron, and half of them are not!

And Yan Ruthless is now facing a huge challenge! This iron-like city, Yan Ruthless can no longer use cannonballs, this is simply impossible to break!

Now the only way is to use people to pile up! There is no other way!

But after all, this is the home of the Yuan Kingdom! In the first two wars, the Yuan Kingdom did not lose many troops! Now the troops of the Yuan Kingdom are all concentrated in this Iron Tree City, once Yan ruthlessly attacks, these people will defend to the death, and Yan Wuru does not know whether he can win or not!

So Yan ruthlessly didn't dare to take risks and try often!

In the next few days, Yan Wuru had been discussing countermeasures with Li Chenghua in Maple Leaf City!

The end result is, dig a tunnel!

Dig a tunnel to Iron Tree City directly ten miles outside of Iron Tree City!

Yan ruthlessly digs a tunnel with all his might, and it will only take five days at most to dig through it!

However, just when Yan ruthlessly dug into the corner of the city wall, Yan ruthlessly discovered a desperate thing!
