Day after day, in the blink of an eye, Faeron and Avril had been in the border town for ten days.

On this day, Feren, who was just about to take Avril out for a walk, suddenly shook his body, and his face changed slightly before returning to the room.

"Master, done?" Seeing the hint of joy on Faeren's face, Avril asked in a low voice.

"Hmm. Feren nodded, "You stay outside first, I'll go in and see what the situation is!"

After speaking, without waiting for Avril to say anything, her mind moved and she returned to the world of Sumeru.

The moment he came to the world of Sumeru, Fei Lun received a stream of information from the Eternal Secret Tower, from which he knew how far the Eternal Secret Tower had reached after its transformation and evolution.

After this transformation and evolution, the various abilities contained in the Eternal Secret Tower have been qualitatively improved, simply put, through the Eternal Secret Tower, Faeron has a stronger strength.

After a brief understanding of the Eternal Secret Tower after the transformation and evolution, and a look at the Sumeru world after the transformation and evolution, Faeron returned to the room with a thought.

"Master, why did you come out so quickly!" Avril was surprised to see Feren come out so quickly.

"I've just briefly understood how far the Eternal Secret Tower has reached after its transformation and evolution, and I'll have time to slowly understand it in the future, and now we can go!" Faeron said with a smile.

"Great, I can finally go, I've had enough of being here!" Avril cheered at Faeron's words.

After simply packing up and settling the accommodation expenses, Faeron and Avril left the border town in a carriage driven by Jack the Minotaur and headed for the Titan Empire.

As soon as they crossed the border of the Moon Empire, a dwarven guard appeared in front of the carriage in which Feren and Avril were riding.

"I've seen two adults!" the leader of the Dwarven Guard saluted Feren and Avril as they stepped out of the carriage.

"Hmm. Faeron nodded.

"We are on the orders of the Dwarven King to escort the two Lords to the Lava Imperial City!" said the leader of the Dwarven Guard in a deep voice.

"Well, lead the way!" Pheren nodded and gestured.

"Yes. The leader of the dwarven guard immediately led his men to the left and right of the carriage and led the way.

If it is said that the feeling of the Moon Empire to Faren is a green world, with all kinds of flowers and trees visible at any time, and even most of the residences are treehouses, then the Titan Empire gives Faren the feeling of a world of iron and fire, and on the way to the Lava Imperial City, you can often see abandoned mines, smoky workshops, a crisp sound of striking iron, and a faint smell of ale.

On the border with the Moon Empire, you can still see some green, and the terrain is relatively flat, but the closer you get to the Lava Imperial City, the less green there is, and the steeper the terrain becomes, replaced by patches of desolate red and steep mountain peaks.

"How long will it take to get to the Lava Imperial City?" asked Faeron.

"In ten days or so, we'll be in the Lava Imperial City!" replied the leader of the Dwarven Guard with a smile.

In the blink of an eye, ten days passed, and as far as the eye could see, I saw a stretch of mountains, but there was no lava imperial city.

"My lord, the Lava Imperial City is coming soon!" said the leader of the Dwarven Guard with a smile.

"Where is the Lava Imperial City? Why didn't I see it?Could it be that the Lava Imperial City is underground?" Hearing the words of the leader of the Dwarven Guard, Faeron asked suspiciously.

"Your Excellency, the Lava Imperial City is indeed underground!" the leader of the Dwarven Guard nodded, leading the carriage through a narrow valley.

At the end of the valley was a large and amazing cave, leading to the dark underground, and at this time there were caravans coming in and out near the cave entrance, and the road they took was relatively remote, so they did not meet anyone.

"My lord, we will reach the Lava Imperial City through this passage, and our king is already waiting for you in the palace!" said the leader of the Dwarven Guard with a smile, and then led the carriage into the passage.

The passage was large and showed obvious traces of excavation by an axe and chisel, and Pheren guessed that it was probably left behind by the dwarves after digging for ore.

The passage is long, but at intervals there are some softly glowing ores embedded in the stone walls, providing enough light for the passage to make it not look dark at all.

Although sitting in the carriage, Fei Lun clearly felt that the carriage was going down little by little, thinking of the Lava Imperial City, and Fei Lun guessed that the Lava Imperial City was probably built next to a lava pool deep underground.

The dwarves are good at crafting all kinds of weapons and equipment, the higher the level of weapons and equipment, the higher the demand for temperature, and the lava pools deep underground can provide a continuous stream of amazing heat, which is the best furnace for dwarves to build weapons and equipment, and it is natural to build the imperial city underground.

Although he didn't deliberately calculate the time, Faeron still knew that after walking this passage to the outside of the Lava Imperial City, they had a total of ten magic hours.

"The length of this passage alone discourages most of the invaders, except for a few races, others are simply dreaming if they want to capture this passage, as long as this passage is destroyed, it will not be ten or eight years, don't think about opening this passage!" Looking at the passage behind him, Faeron said with a smile.

"Underground, we dwarves are not afraid of anyone!" said the leader of the dwarven guard proudly.

Faeron smiled slightly, and did not pick up.

The dwarves may be really powerful underground, but he has countless ways to capture this passage in a short period of time, and even, if he wants, he can completely capture the Lava Imperial City in a short time and wipe out the dwarves.

Of course, Fallon didn't go crazy to that extent, and if nothing else, this would never happen to Fallon.

"My lord, let's go into the city!" said the leader of the Dwarven Guard with a smile.

"Good!" Fallon nodded.

Led by the Dwarven Guard, Faeron rode in a carriage heading towards the Lava Imperial City.

The closer he got to the Lava Imperial City, the clearer Faeron could see the Lava Imperial City.

The Lava Imperial City is built in the center of a lava sea, the blazing lava sea is tumbling, providing sufficient light and heat for the lava imperial city, and it is also the natural fortification of the lava imperial city, if you want to rush into the lava imperial city, you must first conquer this lava sea.

Fei Lun was also a well-informed person, but the moment he saw the Lava Imperial City, he was still amazed by the design of the Lava Imperial City, he didn't expect that someone would be able to use this lava sea to such an extent.

The red-hot magma was pumped into the Lava Imperial City by special magical equipment, some of which became the energy necessary for the operation of the Lava Imperial City, and some of which was dispersed and flowed into the workshops.
