Nelson raised an eyebrow, he walked in the middle of the line, and the fog on either side showed no sign of gathering after it had been split by Medivan.

"Little Gianna is right, the mist here corrodes the skin. But I've seen that you've automatically activated an incredible shield when you've fought before, so there's no problem with that. Medivan continued on his way, without looking back.

"Shields?" Gianna thought of the first battle she had with Nelson, and the other party did have an injury-free shield, and it was so strong that it couldn't do any damage to it even if she used up a full mana gem.

Of course, only Nelson himself knows that this layer of shroud will only work at the beginning of the Hearthstone game.

Knowing that the mist was harmful to the human body, Nelson rubbed his hands together and immediately released five fireballs, causing them to spin around at a rapid speed.

"Looks like your magic shield has a lot of restrictions." Gianna glanced at Nelson's fireball technique and said with a sneer.

Nelson shook his head and didn't reply. Because this is not a secret in itself, and if someone wants to hurt themselves, there is a high probability that they will be dragged into the "Hearthstone battle", so that their lives can at least be somewhat secured.

As we walked on, the fog became thicker and thicker. And the ogre Magi Eureka, who didn't care about the white mist, also began to hesitate to cast a spell to add a protective shield to herself.

"It's here. Remove all your shields, and let me in. Medivan put away his staff, coughed dryly, and took a cautious step forward with his front foot, then leaned down and slowly slid into a cave.

Nelson followed Gianna, shot the small fireballs around her into the sky, and then carefully climbed down the rattan on the cave wall.

Fortunately, the caliber of the cave is relatively large, and even a figure like an ogre can easily enter. Moreover, the material of the vine is obviously unusual, and all of them grasp the vine at the same time, and they do not see any deformation of it.

"Why is this trial ground underground? It seems that very few secret realms are built underground. Blood Elf Jay's two pointed ears twitched, as if confused.

"There are not many races that like to build secret realms underground, it is very likely that we are a goblin race, it seems that I will win the first place in this trial." Goblin Carlo grabbed the vine with one hand, and she looked extra relaxed compared to the others, both because of her petite stature and because of the advantage of her race.

"I'm not sure if Sister Caro will be the first, but I don't think Eureka will get good grades." Gianna watched as the cavern narrowed and narrowed, which made it particularly difficult for Eureka to pass through, and judged that the secret realm was very unfriendly to ogres.

Yukari looked reticent, even a little wooden. Even though Gianna's words made people feel a little cynical, he was not angry, and still climbed down cautiously.

Nelson frowned slightly, he didn't like Gianna's poisonous mouth very much, and at this time, the ogre's slower crawling was completely a safety concern. In case he accidentally slipped off, the few people below were likely to be crushed directly into meatloaf.

"Yukari, you climb on the right, that side is wider, if you can't eat your feet, just say something, I can stop and let you step on my shoulder." Nelson suggested.

"Hey, what a good person!" Gianna blushed for a while, pouted her lips and crawled deeper with her head down.

"Thank you." Yukkari followed Nelson's advice and slowly descended the right wall of the cave, apparently much faster. And Nelson was worried that the stupid big man on his head would really step on the air carelessly, so he kept a very close distance and tensed his nerves to ensure that he could face the emergency.

Because of this, Nielsen's pace has also been slowed down a lot. By the time the rest of the group reached the bottom, he and Yukkari were still slowly climbing down the three-quarters position.

"Gianna, how could you know such a stupid person who would actually want to help an ogre." Goblin Carlo leaned over to Gianna and chuckled quietly.

"Ogres shouldn't learn any magic, and races don't have that talent." The blood elf Jie Or's power was amazing, and he could even hear the whispers of the two girls clearly, and he also cheekily leaned over to participate in the topic.

"To me, this Nelson is even more stupid than an ogre. Isn't it, Gianna? Of course, the purpose of Geo's approach was to get Gianna's attention, but unfortunately it was often the end of a hot face and a cold ass.

Gianna looked up at the entrance of the cave, thoughtful, and did not answer the words of the two of them.

Medivan stood aside, his purple pupils slightly open, watching the performance of the three of them, and then sighed imperceptibly.

"Hey!" Nelson finally jumped down after ten minutes, and before he could stand firmly, he quickly gave up his place and shouted upwards, "Yukari, jump straight down, in the end!"

"Good! Watch out! After a rough reminder, there was a boom, and Yukari's landing made the ground shake.

"Oh my God, do you want to bury us in the ground!" Goblin Carlo was small because she almost fell directly from the shock just now, and she didn't like Yukkari in the first place, so her tone of voice sounded even more angry.

"I'm sorry!" Yukari touched his somewhat scratched knee and apologized honestly.

"Are ogres so easy to bully? Well, maybe it's all good ogres I've met. Nelson didn't want to get involved in their relationship, but looked at the place he was in with interest.

In front of the cave at the bottom was a silver iron door, carved with three irregular lines like tree branches; The lines stretched all the way to the top of the cavern, unfolding into three completely different patterns.

From left to right, the patterns are circles, squares, and triangles, and each shape is also painted with complex patterns inside, like a kind of magic circle.

Except for these three lines, there is not even a gap in the iron gate. And from the outside, the door is unusually hard and heavy, and it should not be possible to open it by ordinary methods.

While Carlo and Geo were still stumbling and complaining about Yukari's dragging, Gianna quieted down and began to study the meaning of these strange patterns overhead.

"This is the realm of mysteries." Seeing that everyone had rested enough, Medivan began to explain, "This secret realm is the work of the great Lord Ronin when he was young, and he gave this secret realm to a kobold mage, so it was finally moved underground. ”

"Ronin! Arcanum?! Nelson got goosebumps when she heard the two names. One is the mage's professional orange card, and the other is an important clue to the "Mystery" series of cards.
