In the center of the big iron cage is a small island, with small trees growing on the island. There is a shallow water flow around the island. The green phantom sighs and walks through the water surface without causing any ripples. She is just a projection of consciousness.

Daphne wanted to reach out to touch Susu, but a faint light curtain appeared in the big iron cage that looked a little worn, blocking her blurred hand.

"Do you want me to help destroy this big iron cage?"

Chen Bing asked when he saw this.

"Yes, Sister Daphne is so pitiful!" Su Su begged with tears in her eyes.

"It's useless. This big iron cage is not an ordinary metal iron cage. It is an integration of the most advanced technology and magic of the mechanical clan. Unless four keys can be found, there is no way to open the iron cage." Daphne shook her head with a smile.

"Four keys?" Chen Bing looked over strangely. There were indeed four large key holes on one side of the iron cage.

Chen Bing wouldn't be surprised if he had one or even two keys, but why did he need four keys to open it?

"It was those four bad guy races who locked Sister Daphne here and prevented her from being free!" Su Su said angrily.

Su Su then talked about the incident.

The land where Chen Bing stood was originally called the Land of Yan.

The Land of Flame was originally a vast desert. The Fire tribe who was good at flames lived on the ground, the Night tribe who could only hide in the darkness, and some Orcs who lived in oasis.

But decades ago, the Machinery Clan came here, and the Fire Clan was no match for it and was forced to give up a large amount of territory. The Machinery Clan became the masters here. They began to transform the Fire Land, and later even created a huge hanging city.

Daphne is a special mechanical plant life made by the mechanical family. She is a mechanical, but also a plant, and can communicate with plants.

The huge area under Chen Bing's feet was originally a desert ruin filled with abandoned machinery, but with Daphne's efforts, it has become a lush forest in just over ten years, and the forest attracted many kind living organisms, because Daphne did not welcome the arrival of those cruel living organisms. If they appeared, Daphne would use the power of plants to drive them away.

In this area ruled by Daphne, she gradually gained the title of "Fairy Forest". Susu came here at that time, but hers were even smaller at that time.

With Daphne's efforts, the land of Yan began to grow on a large scale. After the arrival of the Mechanical Clan, the number of orcs that had already begun to develop began to soar. On the contrary, the area led by the Yan Clan continued to shrink.

The Machinery Clan's interest is all in the Hanging City, and they don't care about Daphne's actions. As long as Daphne is given time, the Flame Earth will become a real Fairy Forest.

But more than ten years ago, another group of mechanical races appeared.

This group of mechanical tribes united the Yan tribe, the Orc tribe and even the Night tribe to launch an attack on the mechanical tribe that ruled this land.

The old mechanical clan was attacked without any defense, and eventually defeated, and the entire mechanical clan was destroyed.

However, in terms of the treatment of Daphne, there were differences in the new machinery, the flame, the orcs and the nights.

The Yan clan strongly demanded the destruction of Daphne, but the orcs were unwilling to do so. No one knew what the new mechanical clan and the night clan had. The final result was that Daphne was locked in this big iron cage.

The big iron cage is a special whole. It is impossible to destroy it or dig a hole from the underground. There are only four races and can only be opened with four keys at the same time. It is impossible to open it without any one.

"In other words, I want to find the keys from the Mechanical Clan, the Flame Clan, the Orc Clan and the Night Clan respectively. Where are these four races now?"

Chen Bing touched his chin.

Finding four keys from four races is not simple, but the more difficult the task, the higher the reward, and of course he will not dislike it.

"They are all living in the hanging cities above the sky now. Those hanging cities can be transformed at will and can be transformed into places that are extremely suitable for their living." Susu pointed to the sky above his head.

The Yan clan, orc, night clan and other races will join forces with the new mechanical clan to deal with the old mechanical clan. In addition to wanting to overthrow the old mechanical clan's rule over this land, one more important reason is that they are attracted by those hanging cities.

Compared with the harsh fire land, Hanging City has greater temptation. After they occupied Hanging City, they understood why the old mechanical tribe spent a huge price to build Hanging City.

"Where is the specific location of the key within each race?" Chen Bing looked up and saw that the entire sky was covered by the hanging city. No wonder the races below united to deal with the old mechanical race.

"I don't know." Su Su lowered her head in shame.

"Adventurer, this is very dangerous, you don't need to take it too seriously. I have been used to it over the years, and even if you save me, I can't repay you. At most, I can only help you repair the machinery."

Daphne said sorry.

"Repair the machinery?" Chen Bing looked at Daphne strangely.

"Well, although I'm very short now, my body can grow up quickly when needed. In the iron cage, I can't even reach out to the iron cage, but outside the iron cage, I can put tiny things in it. I've been locked up here for so long, Susu found a lot of chips of discarded machinery for me. When I was bored, I did analysis and research. Now I am a master of repairing machinery."

Daphne smiled.

"Su Su, be obedient. After this time, you will go to Hanging City to live." Daphne turned to Su Su.

Su Su has always been unwilling to give up and wants to find someone to save her. This time she found someone to help, and it is time to give up.

"Sister Daphne..." Susu looked at Daphne with tears in her eyes, and Daphne just smiled at her.

...

"Brother Adventurer, can you save Sister Daphne from here?"

Su Su took Chen Bing away from the big iron cage and asked Chen Bing a little depressedly. She also knew that it was not easy to find four keys.

"I'll do my best, how can we get back to the hanging island?" Chen Bing glanced around.

"There is a teleportation array near the location where you passed down. I can activate the teleportation array to send you back to the Free City of Hanging Island."

"Liberty City?"

"Well, that's a city built by four races, and they'll do it when they need to communicate," Susu explained.

"That among the four races, are the orcs the most favorable to Daphne?" Chen Bing asked.

"It should be that Sister Daphne has made a lot of contributions to the orcs being able to become stronger. At the beginning, the Orcs strongly expressed that they could not destroy Sister Daphne." Su Su nodded.

"Okay, I'm going to go back to Hanging Island later, and then go find you... By the way, can you get this little guy's good stuff when he upgrades?"

All those who should know are almost done. Chen Bing will prepare to take the brave slime to eat the experience and stars to upgrade.

However, before that, Chen Bing still wanted Susu to help and make the brave Slime stronger.

"That's my ability. I can only use it three times a week. It takes one week to recover. I can't use it again for the time being. However, when it is upgraded, I can try to help, but the specific effect cannot be guaranteed." Susu said embarrassedly.

"That's enough!" Chen Bing was excited.

"roar!"

The Brave Slime roared, and Susu flew down and sat on the head of the Brave Slime.

After Chen Bing set all his experience to be distributed to the brave Slime, he ran towards the stars of experience around him.

In order to facilitate the use of nuclear bombs, Chen Bing never asked the Brave Slime to come out. The Brave Slime's level is still level 17, which is quite low.

The experience contained in the experience stars will increase as the player level increases. The brave slime eats all the experience and the level increases rapidly.

Every time the Brave Slime upgrades, Susu communicates with the Brave Slime on the side, and the Brave Slime roars from time to time.

Although Susu said that her abilities could not be used, with her help, the benefits of the Brave Slime were still very obvious.

When Brave Slime was at level 20, this guy learned the fire-breathing skill and could spit out a long flame tongue with his mouth wide open.

At level 24, it had a set of silver armor on its body, and its entire body was wrapped in the armor, leaving only a pair of dark eyes.

However, after catching the waterside, it liked its new look very much.

When the Brave Slime is promoted to level 26, Chen Bing will return to normal experience allocation and let him upgrade with the Brave Slime.

"This area was sealed by the mechanical tribe, and we can't go to other areas."

Eat all the experience stars nearby, and Chen Bing and the brave Slime reached level 30 and level 29 respectively.

There are a lot of experience stars in the further area, but there is an invisible wall around it to prevent Chen Bing from going.

When Su Su saw Chen Bing looking for a way, she shook her head and said.

"That's it, forget it."

Chen Bing returned to the center of the map.

There, there are still some level treasure chests.

Chen Bing only opened a level treasure chest at level 15, and the level keys after that were saved, which was useless.

He now has a Moonlight Blessing Card and plans to open the level key at one time to make the attributes soar.

Otherwise, even if he has a top-notch equipment and is less than ten levels away from the attributes, he will not get much benefit when he returns to the Hanging Island above in hell mode.

Moreover, Chen Bing discovered that the level treasure chest here was a little different from the ones on the Hanging Island.

The level treasure chest here gives people a strong mechanical metallic feeling, which is more refined and not many, only 30, so the attributes and skills they are opened will be better.

Chen Bing approached with anticipation and wanted to use the moonlight blessing card.

"roar!"

However, there were more than ten meters away from the level treasure chest, and a huge dark golden mechanical dragon in front suddenly jumped out of the ground.

"Invaders! Eliminate!"

The mechanical dragon stood on the ground, twenty or thirty meters high, with dark golden light flashing, and the mechanical eyes emitted a red light, which was even more cruel than the 4-type steel sandworm.

『Mechanical Dragon』

『Happiness 25000』

『??????』

The simple attribute of the mechanical dragon appeared in Chen Bing's eyes, which was indeed very powerful.

Do you want to summon Lex?

20,000 blood, it is not difficult for Lex to kill it.

But Lex only has the last chance to summon, and the mechanical arrow has not yet been received. The mechanical arrow plus the holographic mechanical bow is very likely to trigger Lex's plot. Now, even if you get the mechanical arrow after summoning, it doesn't make much sense.
