"Whoosh-" The silver fighting spirit giant sword pierced the sky with a piercing roar, skimming over the dining heights and heading in the direction of the Lionheart Imperial City.

Most of the soldiers of the expeditionary force, who had already fallen asleep, were awakened by the loud roar and woke up from their sleep to see what was happening.

After figuring out what was going on by asking the sober people, the weary warriors cursed a few times and fell into a deep sleep again.

"Master......" Seeing Ella leave, Monto couldn't help but take a step forward and said a little anxiously.

Li Yunfei smiled faintly, raised his hand to stop Montu, and said, "It's okay, let him be rampant for a while." "Bath...... It won't be long before you will taste the price of arrogance......

Then Li Yunfei casually opened the letter with a lion sealed.

As soon as he opened the letter, he saw a golden light flickering, and lines of words composed of golden fighting qi appeared in mid-air, revealing the content of the letter.

On top of these golden fighting words, they all carry the breath of the Lionheart Emperor.

One by one, the golden words of vindictiveness slowly emerged, forming a letter.

After reading it, Li Yunfei couldn't help frowning. According to the Lionheart's orders, all the acropolis in the first phase must be held for half a year at all costs, otherwise, the giant city where it is located will be severely punished. Ten days later, there will be the first wave of Giant's Mania!

Then he frowned and said to himself, "It's okay, it's enough time for me to do something...... I just don't know if the other Acropolis will last so long...... How does the Emperor know when the giants will attack?"

At this moment, those golden fighting qi in mid-air slowly condensed together, and finally formed the appearance of a small golden sword, which fell towards Li Yunfei's hand.

Li Yunfei grabbed the golden little sword, and his hand couldn't help but fall, and he was caught off guard.

Then he suddenly mobilized the power of the giant, and only then did he hold the golden sword steadily, and a look of surprise appeared on his face.

However, the golden Douqi sword the size of a finger is as heavy as a thousand pounds!

This thing is impressively condensed by a wisp of the Lionheart Emperor's fighting energy, which can be stimulated by his own fighting energy at a critical moment, and then release him.

This thing is equivalent to a blow from a golden swordsman!

Firmly grasping this golden Douqi sword and observing it carefully, Li Yunfei only then understood the horror of the Lionheart Emperor's strength.

He could feel that this little sword of Dou Qi was like a small world, the golden Dou Qi was flowing slowly, circulating on its own, and there was no trace of overflow at all, as if it had been completely enclosed in a ring.

After the fighting spirit is separated from the body, it can still be done this step, and the strength of the Lionheart Emperor can be seen!

Obviously, this Lionheart Emperor's fighting spirit also belongs to a kind of assistance.

Li Yunfei stared at the golden sword, feeling the flow of self-contained fighting qi inside, as if he had an understanding. The mystery of the gold level is likely to lie in this......

At this moment, there was a sound of footsteps, and Li Yunfei put the golden sword into the space ring, and turned his head to look in the direction of the steps.

I saw that Old Pol was walking over with a few members of the Fire Hammer Clan, with a mysterious look on his face.

"Lord Divine Messenger, come quickly, come quickly......" After Lao Pol came over, he grabbed Li Yunfei's sleeve and was about to lead him forward.

Li Yunfei couldn't help but be stunned, and said with a smile: "Patriarch Boer, what's wrong? Is the drawing I gave you too difficult?"

Pol's head shook like a rattle, and he said, "No, no, although the drawings are a little more difficult, I can still understand it, not this, but ...... Hey, you'll find out if you come and see!"

Li Yunfei couldn't help but be very curious, what did this old Pol discover? As masters of casting and smelting, the dwarves of the Fire Hammer Clan played an indispensable role in the construction of Falling Snow City, shouldering the secret mission given by Li Yunfei. Therefore, Bohr has been busy with the dwarves of the Firehammer Clan since he came to the Dining Heights, and this time he did not know what good things he had found.

Under the leadership of Lao Bol, after a while, Li Yunfei had already walked out of the embryonic Snow City and came to the edge of the dining highland.

"It's right there!" Old Pol pointed downward, Li Yunfei looked over, and immediately saw a waterfall-like flow flowing down the stone wall at the edge of the dining heights.

Li Yunfei couldn't help but be stunned, and said, "There's a dark river down here?" There is a large culvert above the stone wall, and the water flows out of it, obviously this is an underground dark river that passes through the dining heights.

"It's not just the Dark River, Lord Divine Envoy, there is a smell of sulfur in this water!, and there is also the mineral sands of the Fire Demon Crystal!" said Old Pol excitedly, "I even saw a bone of a bitten salamander just now!"

Hearing this, Li Yunfei couldn't help but have a flash of lightning in his mind, and immediately said eagerly: "You mean, this dark river leads to Flame Township?"

"It's supposed to be the same dark river, you can't be wrong. Old Pol said excitedly.

The corners of Li Yunfei's mouth raised, and a smile of excitement appeared. I really didn't expect that this dark river would actually lead to the fire demon crystal vein in Flame Township! If this was the case, Falling Snow City's plan would be much more perfect......

Thinking of this, he said to Monto and the others behind him: "Monto, Patriarch Pol, I will go back as soon as I go, and when I am away, I must explore the movements of the giant's territory at any time, and if I encounter a giant attack, I will defend Falling Snow City at all costs!"

"Master, you're going to ......"

"Your Majesty, do you want to ......?"

Before the two of them finished speaking, the corners of Li Yunfei's mouth raised, and he had already jumped down from the edge of the dining heights, jumped into the exit of the dark river, and disappeared in an instant!

Li Yunfei was like a fish, falling into the dark river, and immediately his body swung suddenly, and instantly jumped up and grabbed the upper wall of the culvert.

The river did not completely fill the culvert, but exposed about a third of the space, which was three or four meters high.

Then Li Yunfei relied on his hard body, and his hands were like two iron hooks, firmly piercing the upper wall of the culvert and crawling forward.

This culvert has been washed by the water of the dark river for thousands and hundreds of years, and the inner road is very clean. There were even a lot of glowing mosses growing on the walls of the cave, which shimmered so that the inside could barely be seen clearly.

At the same time, there are some lizards and other creatures living in the culvert around, and there are even a few blind snakes.

It's just that Li Yunfei doesn't have the kung fu to care about this at all now, and after entering the culvert, he immediately uses both hands and feet, relying on his strong strength and hard body, like a huge gecko, and crawls forward quickly on the upper wall of the culvert.

At this time, there was no one else around, Li Yunfei completely showed his strength, not only mobilized the power of the giant, but also used the Burning World Flame Extermination Technique and the Stars Gravity, the speed was several times faster than his previous giant form, it was like a black lightning, swept through the culvert.

After almost a night's work, the green fluorescence around the area gradually faded, and a faint red glow finally appeared in front of the culvert, and the water level of the dark river began to rise, submerging most of the entire culvert in water.

Feeling the impact of the flowing water, the corners of Li Yunfei's mouth lifted, his limbs strengthened again, and quickly passed through the current, the light in front of him became much more dazzling, and he jumped out of a gap above.

"Boom......" In the rippling sound of the water, Li Yunfei was already standing in an underground space with dark red light.

It is surrounded by a flare-like mountain wall, and there are some low iron houses on the hillside in the distance, as well as a statue of Karis.

It is the ancestral land of the Fire Hammer Clan, the Flame Country in the belly of the volcanic mountain!
