In fact, Chang Wei didn't know what kind of reward to ask Mephisto.

He didn't want to make Mephisto obedient and be a lackey. Without solving the problem of Mephisto's true spiritual sustenance law, it is impossible to subdue this old devil.

And apart from this, Chang Wei had little to ask for Mephisto.

To put it bluntly, Chang Wei doesn't like this kind of goods in his heart.

For the time being, the old devil can still be right with Chang Wei, but Chang Wei believes that it won't take too long to kill this old devil just like eating and drinking.

Chicken ribs, nothing worthless.

So throw the question to the old devil and see what Mephisto himself has to say.

After a few moments, He said, "I can trade half of my treasure for freedom." ”

Collection?

Chang Wei said: "What kind of treasure? ”

"Artifacts, precious materials, advanced knowledge of the different civilizations in the universe." Mephisto replied.

When Chang Wei heard this, he was immediately interested.

Artifacts, precious materials, and advanced knowledge are all valuable. Artifacts and materials can be used to refine magic weapons. Profound knowledge is a good thing to enhance Taoism, broaden one's horizons, and nourish one's cultivation.

Chang Wei thought about it and said, "Eighty." ”

"Only half." The old devil won't give an inch.

Chang Wei saw that he was firm, so he didn't say more: "Half is half." ”

Swear it.

Mephisto was delighted. He was thinking of breaking free from the shackles, and now he was finally there. For a while, even with the iron-like heart that the old devil had cultivated for countless years, it was inevitable that it would beat a little faster.

He was a little impatient, rubbed his hands together and said, "How to do it." ”

He also knew that this matter would certainly not be solved in a few words.

Chang Wei smiled: "No hurry. You've been through it for so many years, and it's not in this moment. I need to do some preparation, I'm afraid it will be a few years or a few years. ”

"No problem, I can afford to wait." Mephisto took a breath, waved his hand and said, "I'll wait for thirty or fifty years." ”

If you see hope, everything is not a problem.

Chang Wei smiled: "What about your collection?" ”

Mephisto said: "You helped me break free from the shackles, and I will give it to you." Not now. ”

Chang Wei shook his head and said, "I need a batch of precious materials to refine something." ”

Mephisto was dumbfounded, and after a moment said, "Okay." But most of my treasures are in purgatory. There are very few here. ”

"Let's see." Chang Wei was unceremonious.

Mephisto's Cave House, so to speak, is on the plains of the central area of the floating land. This place is also a lair of giants.

He harnessed the giants to help him build a rude stone temple. Mephisto told Chang Wei that under the stone hall was the exit from this plane.

However, this exit is not safe. As the passage from this derivative space-time to the outer void, it is actually a spatial rift, and the direction of its opening is not a normal void, but a ruin of time.

Exiting the passage, there is a high chance of being swept up in the Ruins of Time.

When Chang Wei heard this, not only did he not frown, but became happy.

Mephisto didn't understand, but didn't ask much. The two walked into the stone hall side by side under the awe-inspiring gaze of the giant race.

Mephisto smiled: "Earlier, when Your Excellency and the Lord God Athena came to this plane, in order to have some fun with Your Excellency, I pondered transforming the giant and giving it the fire of purgatory. These are my works, Infernal Giants. ”

In the stone hall, it is densely packed, and there are thousands of statue-like giants. These giants are covered in scarlet stripes, which are completely different from the normal giants outside.

Chang Wei knew that Mephisto, the old devil, was really playing. Otherwise, if these giants were thrown down, the entire Stuart Kingdom would have been in ruins long ago.

Even if there is a three-headed dragon king Zhenguo, it is impossible to take into account the attacks of so many purgatory giants.

Like Chang Wei, Mephisto could only use a little bit of physical strength. Just as Chang Wei can forge Dao soldiers and even refine magic weapons, Mephisto can also transform giants into purgatory giants.

Although the efficiency is not very high.

Entering the stone hall, Mephisto led the way, all the way through the main hall to the apse.

In the center of the apse, a huge altar suppressed. Mephisto said, "Move this altar away, and below is the exit." ”

Chang Wei looked at it a few more times, nodded, and his gaze crossed the altar and landed behind the altar.

A big hill of messy stuff.

Mephisto was a little embarrassed: "Those are my treasures." ”

"Garbage heap?"

Chang Wei teased and walked over.

Although this mountain of garbage is like something, it doesn't look very good. But the invisible layer, the various light qi that lingers and spews is shocking.

Absolutely all good stuff!

In order to break free from the shackles, Mephisto pretended to be generous: "These are even deposits, how about it?" ”

Chang Wei laughed, spread out his palm and pressed it, and a wisp of mana turned into a fishing net, netting the garbage pile more than ten meters high, and all of it was collected into the cave space at once.

Mephisto's eyes widened, and he was really unkind.

For a while, it is inevitable that there will be a little pain. You must know this pile, but all the treasures of the Eye that He has collected over the years in this plane.

It can almost be said to be the essence of this plane.

All at once it was gone, Mephisto's flesh ached, but it was all that. It was worth it compared to breaking free from the shackles, and He comforted himself secretly.

Chang Wei received these things, and he was also satisfied. With so many good materials, many ideas can be put on the agenda, and it is not a problem to refine three or five seven or eight magic weapons.

However, the meal has to be eaten one bite at a time, and the road has to be eaten step by step. So refining magic weapons or something, helping Mephisto break free from the shackles or something, no hurry, no hurry.

Then he set his eyes on the altar again.

Mephisto knew what he meant, and said, "You guessed right. The torso of Ouranos was suppressed in the passage. Want to check it out? ”

Chang Wei thought for a while and shook his head: "Not busy." ”

said: "Lao Mo, you have to take your time." I'm not going to stay longer. Do you know the annex I built in the Valyrian hills? Come to me if you have something. Wait until I'm ready, come back here and solve your problems. ”

Mephisto wasn't worried that Chang Wei wouldn't be able to solve the problem. If not, the oath made by the two parties before will definitely make Chang Wei pay the price he deserves.

So he said, "I know that Your Excellency is in the annex of the Valyrian Mountains. ”

Chang Wei bowed his head: "In addition, don't toss me in the mortal realm." ”

Mephisto said indifferently, "You have the final say." ”

It didn't matter. Mortals are like ants in His eyes. It is impossible for a mortal to find trouble with an ant's nest every day, and he is not obsessed with having fun with mortals.

Then I looked at Athena. He placed him in the side temple next to him, still sleeping.

However, Chang Wei didn't plan to leave Athena here, and when she left, she would take her back with her.
