The two stood in front of the bronze gate crawling with thunder and flames, as small as two black dots.

The third elder Xu Ke seemed to see Qin Han's shock, and slowly introduced:

"This place was originally an ancient Great Sect site, after the first generation of my North Sword Gate patriarch traveled here, saw that here surrounded by mountains and rivers, one hundred and eight peaks towering, then rebuilt the palace pavilion on the ruins of the dilapidated mountains and rivers, hundreds of years passed away, and now it is difficult to find the traces left by the Great Sect, only one or two things are still silently telling the glory of the Great Sect in the past, and this bronze gate mottled by the years in the Thunder Fire Peak is just one of them."

"It's been so long, there won't be any amazing inheritance in it!" Qin Han was surprised.

The Third Elder smiled, "It is said that when the ancestor opened this door in the past, he did get some inheritance, but it was not yet amazing. When the Great Sect perished, everything that should have been taken away was taken away, and time evolved, and now, it is only full of thunder and flames, as well as some low-level demon beasts, which can only be regarded as a place of practice for disciples whose exercises are biased towards the thunder and fire attributes. ”

Qin Han was stunned.

The Third Elder nodded, and then instructed: "This Thunder Fire Realm is divided into three areas, after you enter, just hunt the Thunder Fire Beast in the low-level area, remember, don't go too deep!" In addition, if you have the ability to kill 10,000 Thunder Fire Beasts in the Thunder Fire Realm, you may be rewarded by the Thunder Fire Realm. ”

"What reward?" Qin Han was curious.

"You'll know when you go in!" The third elder smiled, and then with a wave of his sleeves, a thick spiritual power appeared, smashing into the bronze door with lightning speed.

Bang!

With the impact of spiritual power, the bronze door made an earth-shattering bang. The closed door opened little by little.

Through the crack in the door, there was a flash of lightning, and the flames burned, as if they were about to overflow from inside.

A world full of thunder and fire was presented in Qin Han's eyes little by little.

"Go inside, the door will open again in five days!"

The heavy voice of the three elders sounded, Qin Han turned around and bowed to the three elders, and resolutely stepped into the bronze gate.

Walking into the gate, he looked back and saw that the three elders were nodding at him outside, and then, the bronze gate slowly closed, and the last trace of light disappeared.

He began to look at the secret realm in front of him, the sky was covered by thick clouds, and in the clouds, thunder and flames were intertwined and danced, and these thunders and flames poured down from the sky from time to time, bombarding and burning the earth.

The earth, which has withstood the thunderous bombardment, is uneven. Under the scorching flames, the soil was scorched and blackened.

The whole world took on an oppressive dark red, and the sky was constantly thundering and rolling.

"Where's the Thunder Fire Beast?" Qin Han was a little puzzled, the whole world was filled with the aura of destruction, and the surroundings were barren, and he couldn't detect the breath of any living beings.

Just when he was puzzled, suddenly the whole person was alarmed, and a throbbing of death appeared above his head.

Hardly without any hesitation, he quickly moved sideways to the right.

In an instant, a thunderbolt entwined with flames fell from the sky and bombarded the place where he was standing, and the earth was blasted out of a large crater more than a foot deep!

In the deep pit, the purple flames were burning, and there were thunder flickering and swimming in the center of the flames, giving people a terrifying sense of threat.

Qin Han's scalp was numb, this thunder was extremely fast, it appeared too abruptly, although he moved out horizontally, but it was still affected by the aftermath, the whole person was overturned and thrown away for several meters, and the wisps of thunder made him stiff all over.

But that's lucky enough!

If Fang Cai is a step slower and is hit by this thunder, it is very likely to be melted directly!

"It seems that you have to be careful with the top of your head after that." He was in awe of the sky.

Here, it is full of dangers.

He struggled to his feet, glanced at the unextinguished flames in the pit, and got up to leave.

But at this moment, the cold voice of the system sounded suddenly:

【Host please select】

[Option 1, march straight ahead, enter the sea of thunder and fire, and use the heavenly thunder and heavenly fire to forge the body, which has a chance to condense the body of thunder and fire and break through the Qi cultivation realm. However, the lowest strength of the Thunder Fire Beasts in the Sea of Thunder and Fire is in the Qi Cultivation Realm, and there are even more in the Human Dan Realm, so it is not recommended that the host enter it. 】

[Option 2, go to the right front, there are a considerable number of Thunder and Fire Beasts, the protagonist can hunt Thunder and Fire Beasts, when the number of Thunder and Fire Beasts hunted is enough, there is a chance to summon the Thunder Fire List, and get a certain reward from the Thunder Fire List. 】

[In view of the host's situation, it is recommended that the host choose the second option.] 】

This familiar voice hasn't appeared for too long, Qin Han frowned, what is this bird system doing now? Could it be that he wants to see him Qin someone rise from the end of the micro and is about to become a Gaidai master, and then he can't stand it anymore?

Or does this dog system want to come out and brush up on his presence in front of his master?

He had a strange look in his eyes, but he was pressed for time, and he couldn't help but start to seriously examine the two options.

After a moment, he sneered.

Obviously, he didn't have a choice.

If he chooses to enter the Sea of Thunder and Fire, once he breaks through the Qi Cultivation Realm, it will not be beneficial to the competition after half a month, because it is impossible for him to cultivate the Qi Cultivation Realm to perfection in half a month.

He looked at the system's settlement panel questioningly, and then chose the second item without hesitation.

A moment later, a memory flooded into my mind from the system.

"It's the map structure of this Thunder and Fire Secret Realm."

After browsing this memory, Qin Han muttered, he didn't expect that the system still has this kind of anti-heaven function, if he goes out to travel and break into some secret realm in the future, the system is a living navigation, and he doesn't have to bother to find his way.

The map provided by the system is very detailed, and mountains, flats, and ravines are marked and introduced.

After a general look, the entire Thunder and Fire Secret Realm is divided into three areas: the outer area, the inner area and the core area.

In the outer areas, most of the strength of the Thunder Fire Beasts is in the two basic realms, and the inner area is full of Thunder Fire Beasts in the Human Dan Realm and the Earth Dan Realm, as for the final core area, the worst strength is also the Tiandan Realm, and there is even the existence of the Divine Transformation Realm.

Those are naturally forbidden places that he can't set foot in, and now he only needs to hunt in the outer areas.

According to the map in his mind, there was a valley three miles away, and when he entered the secret realm, he had not seen a thunder fire beast until now, and he felt that in those valleys where thunder and lightning were dense, there might be a thunder and fire beast.

He looked for his direction and prepared to head to the valley.

But before he could move, the voice of the system sounded in his head again:

[Congratulations to the host for choosing the right one and getting a copy of the "General Outline of Boxing"!] Get a bottle of the Fountain of Immortality! 】

"General Outline of Boxing"? The Fountain of Immortality?

Consciousness sank into my mind, and there were two more imprints in the storage compartment in the system, one was a bottle and the other was a book.
