There are fewer materials in the third floor treasure house, but the value is on average higher than the first two floors.

Now, for Su Lisen, there is not much that attracts him.

Most metal minerals are affected by the opening of several space crack channels, and the added energy corrodes them into powder, but this also saves the refining step. Just simple filtering and screening can obtain a relatively pure metal...

Su Lisen only collected a few portions of this type of high-purity metal powder to refine and make disposable six-star 'armor-breaking' arrows.

The rest of the supplies are helping A Ling, Mei Xue, Du Qing, Yuan Ximeizhi and others choose instantly available items...

He did not get involved in the search and transportation actions of their family team. He could not carry much by himself. He only wanted to be fine but not too many, just use it immediately.

Then Liu Yunji found the key to open the fourth floor treasure house. After Su Lisen and his friends left with Liu Yunji, Count Yi Shi and others from various forces in the six dynasties were truly relieved. Looking at Su Lisen's back, they began to feel lucky...

After seeing off the "Big Demon King" and their families decided to take it slow first and not go to the fourth floor with Su Lisen and the others to "join the fun" for the time being.

But the "follower" who can't be beaten, then who, Grand Duke Haihuang and others left some people to continue searching on the third floor, and followed Su Lisen with a few elites, and Liuyunji and others...

The fourth floor is really different from the first three floors.

Its starting power is derived from the geothermal energy in the magma area below, and it has a layer of extremely high temperature barrier protection layer. It can only pass through it under the protection of specially made full-body armor; or it is also possible to use heat-resistant armor above six-star level.

"You are all guarding outside!"

Grand Duke Haihuang deliberately loudly ordered his subordinates to escort and his alliance forces to bring only 30 people with six-star armor to the high-temperature barrier protective layer...

Those who were as strong as their entry, or even slightly won were Du Qing, Geng Yun, Mei Xue, and Zhou Yuan, Beliezan, and his fiancee Huo Yu family.

Not counting Su Lisen, A Ling and his team have the battle star fog armor. Excluding Liu Yunji, who has special armor, has two masters and servants, the rest have more than 40 armors.

"Haha, I am worthy of being a high-level player in the War Star Academy!"

Grand Duke Haihuang smiled sinisterly, "Marty Liuyun, will your agreement take effect even if this is effective?"

This old ghost aims to provoke discord.

Without giving Liu Yunji a chance to defend himself, he laughed loudly, nodded to Su Lisen and said hello, turning around and taking the thirty people from his side and swaying away...

Inside the high temperature layer is another world.

It is better to say that it is the fourth floor treasure house, it is a palace-style building engraved in the underground rock caves.

Follow the stone steps, turn out to the end of the loop corridor, and then pass through the door hole between the two large stone pillars, and then arrive at the square in front of the stone hall.

There are hundreds of human-shaped or animal-like stone sculptures in the square, guarding a huge stone tablet up to 100 meters high. The contents of the stele record the life and glory of Liu Shuiyun, as well as the heroic deeds of several outstanding talents among the descendants of Liu Yun Mansion...

The old ghosts and the others stood in front of the big stone tablet and saluted respectfully.

But when Liuyunji, Su Lisen and the others approached, they saw another face of the old ghost Haihuang.

"Marquis Liuyun, I miss the glory of your ancestors, which is enough to admire tens of thousands of generations of human beings."

The old ghost smiled - the implication is that you Liuyun is far inferior to your ancestors, and you want to open the inheritance of Liuyun Mansion? Why not give up? What's more, you are expressing that when Liuyun Mansion is declining, don't think about rising again, right?!

"Crack!"

Liuyun was so young that he suffered such an unbearable humiliation from the old ghost in front of the engravings of the ancestors. His fists were tightly pinched and his knuckles turned white.

"The Liu family's God of War and the Emperor are indeed admirable."

Su Lisen took over the conversation, "Da Da Gong Haihuang, did your ancestors have produced god-level heroes, so why do we admire them?"

"Junior, don't be too arrogant!"

Grand Duke Haihuang's face immediately became extremely smelly, and before he could get angry, the five-star old ghosts behind him all jumped out in anger and roared at Su Lisen.

"I am arrogant or not, you should understand Grand Duke Haihuang." It means that there is no old ghost who is arrogant?!

Su Lisen snorted coldly, "In front of all the heroes of Liuyun Mansion, you should say less!"

His mind power flew at a rapid speed, slew three inches in front of the eyes of angered old ghosts.

He had not yet figured out Liu Yunji's master and servant's plan, and he did not expect to turn against Hai Huang's old ghost at this moment, otherwise...

"hiss!"

"you……?!"

The old ghosts were all so shocked that their faces were pale.

At present, who can withstand Su Lisen's sneak attack from the flying blade of his mind?!

In the face of absolute strength, no matter how angry he is, he has to endure it.

"Hahaha."

The old ghost Haihuang changed his sinister face and smiled brightly, "I'm just a joke with Nephew Liuyun Shishi."

He pointed to the main hall behind hundreds of stone sculptures, and the closed stone door, "The old nephew should have a way to open it, right? I was anxious for a moment and said nothing. I apologize to you, the old nephew!"

He just ignored Su Lisen and said to Liu Yun: "If the nephew can open it, he can put forward any conditions. As long as I can agree, I will do it."

This is a nonsense that fools people. The old ghost must judge what "he can agree" himself before he can do it.

"Grand Duke Haihuang, please forgive me, Liuyunjiu has no way to open it."

Liu Yunji's words made the old ghost's face completely dark.

But he continued: "However, my ancestors left behind the legacy. The fourth floor was originally a place for the children of my Liuyun Mansion to take the teaching skills. Anyone who can pass this stone carving battle formation is qualified and can only be qualified to enter the stone hall."

He spread his hands and said, "Liuyunji is not talented, and he is not sure that he can pass the assessment of the stone formation."

"……Hahaha."

The old ghost's gloomy face suddenly changed, and he smiled relieved, "Of course I believe in Liuyun's nephew."

He waved his hand and made a way for the rest of the people to open up a passage.

"Su Lisen, Su Hou!"

The old ghost obviously didn't want Su Lisen to follow Liu Yunji and smiled and said, "Do you and me have a new discussion?"

He smiled without any prejudice, "I had known that Su Hou had returned from his studies at Zhanxing Academy, but he didn't expect that he was so powerful. I was absent-minded and hoped that Su Hou would not be bothered with old people like me who were about to die."

"Not."

Su Lisen smiled and said, "Su just had an appointment with Liuyun Hou before and promised to protect him before the fifth floor."

"If Grand Duke Haihuang intends to renegotiate and agree, everything can be discussed with mentor Du Qing, Earl Mei Xue and others."

His mind power flying blade was not retracted, and it was flying around his body, making it difficult for outsiders to get close to him.

Just so strongly led the way, following Liu Yunji to break into the stone carving formation...

"snort!"

The old ghost Haihuang obviously didn't really want to negotiate a cooperation agreement, he just wanted to hold Su Lisen back.

He said in a slight and uneven manner: "I wish Su Jue and Marquis Liuyun to pass the barrier smoothly."

"Well, with the blessings of Grand Duke Haihuang, I am more confident. Thank you here!"

Su Lisen just wanted to get angry with this old ghost.

"Damn little devil, I'm so angry!"

After the backs of Grand Duke Haihuang and Su Lisen disappeared into the stone sculpture battle formation, they were so angry that they vomited blood.

He didn't want to lose his belongings in front of Su Lisen, but he couldn't help it. He still lost a big shot in front of Du Qing, Mei Xue and the others...

Chu Yang, Chu Xiao, Li Xing and others and a group of old men in black robe hurriedly surrounded Hai Huang's old ghost to cover the face that fell to the ground for him.

Su Lisen obviously didn't know the state of Lao Gui at this time. After entering the stone sculpture battle formation with Liu Yunji, he seemed to have activated some three-dimensional projection game magic array space. They seemed to have been teleported into a battlefield where ancient cold soldiers fought...
