For Xu Feng, the effect of the fusion box was not as great as he imagined; Combining three identical items into a higher-level item sounds beautiful, but it is not a simple matter to find three identical items, for life professionals, the fusion box may be an artifact, but for Xu Feng, this fusion box is not as important as the Qingteng Demon King imagined;

It's just that now the Qingteng Demon King can't give other life-buying treasures, as for the promise, now Xu Feng doesn't have the ability to ensure that after the Qingteng Demon King gets out of trouble again, he can continue to keep his promise, and hopes that the Qingteng Demon King will keep his promise, which is tantamount to a joke;

"Tell me how I can help you?" Xu Feng asked with a light finger, and glanced up at Ke Rui'er, who was constantly picking something from one plant after another, not noticing Xu Feng's side at all;

The Green Vine Demon King did not speak, but branched out a small rattan from the root, stretched out towards Xu Feng, and when he crossed the golden light curtain prohibition, the cyan rattan trembled uncontrollably, and a trace of golden sparks continued to explode, and the surface of the rattan had begun to turn black and scorched;

The tiny rattan still struggled to penetrate the golden light curtain prohibition, and after it stretched out, a flower bone the size of a fingernail began to appear at the top of the rattan, which blossomed and bore fruit almost immediately, and a cyan fruit the size of a sesame seed fell, Xu Feng reached out to catch it;

Rumble~

With a low sound, the tiny green vines that poked out of the whole plant turned into ashes;

Ke Ruier seemed to feel a strange energy fluctuation, looked up, and saw Xu Feng standing on the safe passage, staring intently at a huge green vine;

"Be careful, every plant here is a hundred times stronger than you, a thousand times, get close and be careful to be caught by them as flower fertilizer." Ke Ruier still reminded uneasily;

Xu Feng glanced up at Ke Ruier, nodded, and didn't say anything;

"Okay, I've almost collected all the materials I need, you know, it's not an easy thing to open the trial tower, and it costs a lot." With a hint of fatigue on her face, she continued, "Let's go, it's too dangerous here. ”

Xu Feng followed behind Ke Ruier and walked out, his palm, a cyan sesame-sized fruit, was trying to break through the skin of his palm and drill in, and soon got into the flesh and blood of his palm;

"I have condensed all the essence of the body into this fruit, and it won't be long before the green vine body loses its vitality and dies." The voice of the Qingteng Demon King sounded in his mind, this voice was full of exhaustion, it seemed that this means of getting out was not without price for the Qingteng Demon King;

"Alright, tell me about the Fusion Box." Xu Feng asked;

The seed condensed by the Qingteng Demon King only exuded a faint energy fluctuation, and after drilling into the flesh and blood of the palm of his hand, he couldn't sense it at all, only Xu Feng could communicate with it freely;

The current Qingteng Demon King has no ability to threaten Xu Feng at all, even if he returns to the earth, I am afraid that in a short period of time, he will not be able to recover to his previous peak strength.

"The Fusion Box is the alchemy of magicians, and only those who are highly skilled in magic will focus on it." The Qingteng Demon King continued with exhaustion in his words: "The owner of this magic tower, Kai Ruijin, is a great magician with such strength, as long as you follow him, you can obtain the information of the Fusion Box. ”

Xu Feng: "......"

A great magician like Kai Ruijin is not at all accessible to Xu Feng now, and the Qingteng Demon King is probably only after being caught by Kai Ruijin that he got the news about the Fusion Box from a few words;

For Xu Feng, who is a follower of Limurdo, it is only a matter of time before he gets such news;

Soon, the two returned to the ninth floor together, and Limurdo also came out of the laboratory and walked with the two towards the tallest building in the restaurant;

This is a nine-storey building, the first floor is the largest, the higher it goes, the smaller the area, the top layer is like a triangular spire, and the whole building looks as if a pyramid is stretched up and down, in Xu Feng's eyes, it looks very weird;

"This is the Trial Tower, the first layer is the Knight Apprentice level, the second layer is the Reserve Knight level, and the third layer is the Black Iron Knight level." Ke Ruier pointed to the building in front of him and said: "Every time you open the trial tower, it takes a lot of resources, so don't think about going in in a short time, you must seize this opportunity, but don't be beaten out as soon as you enter." ”

"In the trial tower, what is there that can quickly improve my strength?" Xu Feng asked;

"It's all demonic beasts, from the lowest-level tooth hunter rat to the sky-swallowing golden scale python, it is said that at the top of the top, there is also a demonic beast that has reached the level of a holy knight, there are a lot of them, after you go in, kill as much as you want, only in actual combat, can you improve your strength." A hint of amusement flashed in Curry's eyes.

The trial tower is specially used by the great magician Kaireli to quickly improve the strength of the followers of the disciples under the seat, the method is simple and rude, that is, to let them improve their strength in actual combat, there is no shortage of followers who die in it, becoming the rations of the monsters;

Xu Feng was stunned for a moment, and then his heart became ecstatic, in this world, as long as you hunt demonic beasts, you can get experience points to upgrade, if you rely on cultivation alone, I don't know how many years it will take to recover to the Seven Stars, that is, the level of the title knight in this world;

Originally, in Jisang Town, Xu Feng locked his eyes on the land of monsters, and wanted to upgrade with the monster slimes in the land of monsters, but in his previous life, he knew that the level of these slimes ranged from the weakest one star to the most powerful nine stars, and they could be quickly improved by hunting them;

I didn't expect that after coming here, there would be a trial tower comparable to the land of monsters, which was simply an unexpected joy;

"Do you want to start now?" Xu Feng couldn't help but clench the two-handed sword in his hand, with a look of surprise on his face;

Seeing Xu Feng's eager expression, a smile appeared on Ke Ruier's face, almost all the people who were about to enter the trial tower had Xu Feng's expression, but when they came out, it was a different look, Ke Ruier was now looking forward to what kind of expression Xu Feng would have when he walked out of the trial tower.

"Stand back, I'm going to open the Trial Tower." Reciting a spell, Kerryl took out the precious materials one by one, and soon, the surface of the originally silent trial tower was covered with a faint red light;

"Don't die in there!" Limurdo's face was full of worry, and he whispered to Xu Feng.
