"If you want the key in my hand, you can come up and try it now, and if you dare to do anything crooked, don't blame me for being unkind." Yan Sen said coldly, his gaze swept over the bodies of everyone in the square.

Feeling Yan Sen's fierce momentum, the people who had been thinking carefully also died down, as for snatching the key in Yan Sen's hand, they didn't have that ability.

"You guy has been wandering in the northeast, how could you come to our northwest region, I heard that the northeast region also has a considerable treasure." Liu Bai said with a smile.

"The treasure in the northeast has a super dynasty that takes a fancy to it, and it is troublesome to get some benefits, relatively speaking, the northwest region is the weakest of the several regions." Yan Sen said lightly.

"Let's not talk about it and start the most important step." Liu Bai glanced at Lin Mu and Lin Dong, and then looked at the four bronze gates, with a scorching light in his eyes.

Lin Mu nodded slightly and walked over with everyone.

Liu Bai's palm stretched out, and the secret key in his palm emitted a ray of light, and at the same time, one of the four bronze doors also seeped out a lustre.

The key floated away from Liu Bai's hand, and the light became more and more intense, and finally the light condensed, forming a magical rune that shone on the closed bronze gate.

"Crunch!"

The bronze door, which had been closed for an unknown amount of time, slowly opened, and an ancient aura emanated from it.

"It seems that my Ancient Key is the key to this bronze gate, so we'll enter first." The scorching light in Liu Bai's eyes became more and more intense, and after saying a word, with a wave of his palm, the ancient secret key emitted a circle of light, enveloping all of them, and finally rushed into the bronze gate with a bang.

And as Liu Bai entered, the bronze gate closed again.

"Let's do it too."

Seeing that Liu Bai had already entered, Lin Dong, Xiao Yan and Yan Sen all took out the ancient secret key, and the remaining three gates were all opened, and Yan Sen took the lead in entering the gate that belonged to him.

"Xiao Yan, you go in alone, be careful." Lin Mu said that he was more interested in the Blue Dragon Hall than the White Tiger Palace.

"Big brother, I'll be careful." Xiao Yan nodded and swept into the bronze gate that belonged to him.

The secret key in Lin Mu's hand emitted a circle of light, enveloping Lin Mu and the others, and then they entered the last bronze gate together.

After Lin Mu and the others entered, the three bronze doors were closed again, just like when the dust was sealed before, and they did not move for eternity.

After a brief period of darkness, the light reappeared.

What caught his eye was a huge giant gate, standing in front of this huge gate, Lin Mu and the others were as small as ants, looking up, with a sense of oppression.

The giant gate was not closed, and when he looked behind the giant gate, he only saw a hazy and very weird place.

"Is this the inheritance place of the Four Great Xuanzongs?" Lin Dong looked at the giant gate and muttered to himself.

"Buzz!"

At this time, the blue light condensed above the giant gate, and an ancient font faintly appeared.

"Four Elephant Xuanzong, Qinglong Palace."

Lin Mu didn't know the ancient font, but the first time he saw it, he naturally knew its meaning.

"The Qinglong Trial, Nine Deaths and One Life, enter with caution, enter with caution."

When Lin Mu and the others were shocked in their hearts, the original font disappeared, and a few big characters resurfaced.

"The way back has been sealed, and we have no other way to go now except to pass this trial, don't be frightened by the words above." Lin Mu said lightly.

"Well, I want to see what this Blue Dragon Trial is like." Lin Dong nodded slightly, and a scorching light flashed in his eyes.

"Brother Lin Mu, I won't hold you back." Qingtan said solemnly.

"Neither will I." Xiao Lei also said.

"I never thought that you would drag your feet, in terms of cultivation qualifications, Qingtan is the best of the three of us, and we may have to rely on Qingtan for protection in the future." Lin Mu smiled.

"I will definitely protect Brother Lin Mu and Brother Lin Dong." Qingtan smiled happily.

"Let's go." Lin Mu waved his hand and took the lead in stepping into the giant gate.

At the moment of stepping into the giant gate, the scenery in front of him changed suddenly, a thunderous sound sounded in the ears, in front of a silver ocean, the dark clouds above the ocean were shrouded, in which the thunder surged, and a huge thunder roared down like an angry dragon, bombarding the silver ocean.

"This silver ocean is actually condensed by thunder and lightning." Lin Dong said with a little numbness in his scalp.

"This Thunder Sea is an excellent treasure place for Xiao Lei to cultivate the Thunder God Body." Lin Mu smiled faintly, he had known the situation here for a long time, so he brought Xiao Lei in.

"I'll try." A glint flashed in Xiao Lei's eyes, and he stepped into the sea of thunder.

"Whew!"

A trace of violent force poured into his body along the soles of his feet, like an electric shock, his hair stood upside down, his mouth was open, and a puff of black smoke came out, which looked extremely comical.

However, Xiao Lei's expression was very excited, the energy in this thunder sea was very helpful for cultivating the thunder god body, and he turned around and said: "Big brother, with the thunder and lightning energy in the thunder sea, I am sure that I will cultivate the thunder god body to Dacheng in a short period of time." ”

"Then you should work hard to cultivate." Lin Mu nodded slightly, and then said to Qing Tan: "Qing Tan, this thunder and lightning are compatible with your Yin and Cold Yuan Force, you don't have to force yourself." ”

"Brother Lin Mu, I can do it." Qingtan wants to be strong.

"It won't do you any good to pass this thunder and lightning trial, even if you can, there's no need to suffer that sin, wait for us to go together, I will protect you with Yuan Li." Lin Mu Road.

"Thank you, Brother Lin Mu." Qingtan smiled, she felt a strong love from Lin Mu's voice.

"Let's go." Lin Mudao wrapped Qingtan with Yuan Force, and the two stepped into the Thunder Sea together.

His Yuan Force is a thunder attribute, but it can't completely resist the thunder and lightning, but he has cultivated the Thunder God Body, and this thunder and lightning is equivalent to tickling him.

And those thunder and lightning energies that seeped into Qing Tan's body, he would devour them with the Thunder Heavenly Seal.

Therefore, crossing this thunder sea is more like crossing an ordinary ocean for him.

It was not so easy for Lin Dong to deal with, but except for suffering some crimes, there was no danger, but after the tempering of thunder and lightning, the strength of his body was gradually improving.

The sea of thunder is boundless, as if there is no end.

Half a month later. Lin Dong's physical strength has been greatly improved, and he has completely adapted to this thunder sea.

"Whoa!"

Suddenly, the thunder sea seemed to be boiling, the thunder slurry surged, and something seemed to be coming out in the depths of the thunder sea.

Lin Mu's expression also became a little more serious, staring closely at the place where the thunder slurry was surging.

After a while, an extremely large shadow slowly surged out from the thunder sea, and thousands of zhang in a radius were shrouded in that shadow

"Hurry back." Lin Mu shouted, and then quickly retreated with Qing Tan, until he withdrew from the shadow before stopping, and Lin Dong and Xiao Lei also followed.

With a loud bang, the huge shadow rushed out of the sea, setting off a monstrous wave, and Lin Mu condensed a spiritual power barrier in front of him, blocking the churning thunder pulp.
