"Are we going in?" asked Danica.

Phyllis frowned in confusion. It was said that the door had been opened, so just go in, but she always felt something was wrong. Danica probably felt the same when she asked this question - this mechanism is too simple. The switch is near the iron door, and there is no need to crack anything. Just press it directly. Such a simple way to open the door is simply sorry for such a thick iron door.

"See there is nothing that we can try." Phyllis said.

The two girls searched around and found a crowbar that was abandoned here at some time. Although the crowbar was rusty, it was still quite strong in his hands.

Danica glanced at Phyllis, grabbed the crowbar and carefully reached into the door.

There was no movement. Could it be that this door could pass through so easily? Danica grabbed the crowbar with both hands and swept it left and right, but there was still no movement.

Maybe they were thinking too much. Danica was about to pull out the crowbar, but she accidentally touched the iron gate. In fact, she just wiped it lightly, but the iron gate suddenly fell down quickly. Danica felt something was wrong and quickly let go, but she was still staggered and almost fell down.

With a loud bang, the iron door closed again, and the crowbar was directly crushed under huge pressure.

"You can't touch the iron gate when you pass here?" Danica was a little confused with the loud noise. She waited for a moment before saying something.

"Maybe." Phyllis said, "at least we can confirm that this is a very sinister mechanism. The speed and force of the iron gate descending are definitely not achieved by natural landing. The impact force of natural landing at such a small height will never smash a solid crowbar like this. This iron gate should be controlled by the mechanism."

Looking at the closed iron door, Danica said, "Try it again." She pressed the switch again, and the iron door rose up with the squeaking sound.

There was no handy tool around, so there was no way. Danica picked up the iron rod that was cut in half again and slowly stretched over. She planned to try again to see if it would trigger the mechanism once she touched the iron gate.

This time Danica had just reached the crowbar into the door less than ten centimeters, and she was sure that she had never touched anything. The iron door fell down again without any warning.

Fortunately, Danica was prepared this time and let go of her hand in time and was not taken down, but this did not bring any good mood. She turned to Phyllis and complained, "What's this!"

"Who knows what those short guys think?" Phyllis said helplessly.

The two girls tried several times next time. Sometimes they just put the crowbar into the iron door and fell down. Sometimes they needed to touch the iron door before they fell down. Sometimes they were useless to touch it. The iron door fell down about ten seconds after it was lifted. Sometimes it was two seconds.

"It should be just these four situations." Phyllis threw the crowbar that had been cut off and folded several times aside. "It is the best situation to fall after touching it. It is something we can control. Just pay attention. It is okay to fall ten seconds after being lifted. This period of time is enough for us to run over, but if the other two situations occur, we will die under this iron gate."

"The key is that these situations are irregular." Danica said sitting on a stone.

"No, this is regular." Phyllis said with a frown, picking up a sharp stone on the ground and calculating it.

The ground of the mine was quite soft, Philis carved it on it with a stone, and Danica also came over to take a look, but Philis used many complex symbols and calculation methods in the calculation process. She couldn't understand it at all.

After waiting for more than ten minutes, when he saw Philis stand up and throw the stone, Danica asked, "How is it? Can you find the rules?"

Phyllis frowned and said, "I found it, but according to my calculations, we only have one chance to try it. If I miss it, the door will no longer be opened."

"Not turned on?" Danica asked.

"At least in the logical algorithm, this door will be locked." Phyllis explained.

"Okay, what should we do?" Now if we want to continue moving forward, we must take a lot of risks. This expedition was proposed and planned by Phyllis. In this case, of course she still needs to make an idea.

Phyllis patted the gray on his hand and said with a firm look: "Of course I'm seizing the last opportunity."

"Oh, okay." Danica did not raise any objection, but obediently accepted Phyllis' decision. Although this was in great danger - the biggest danger came from Phyllis' calculations. She did not fully grasp that her deduction was absolutely correct. After all, she still had too little data. Once the judgment was wrong, they would bear the punishment of death. But both girls knew very well that they were here for the ruins. Since it was an "exploration", of course they had to bear certain risks. If they really wanted to live a stable life, they should not come here, or they should not come out to practice at all.

Phyllis moved her hands and took out a ruby-laced ring from the storage bracelet and put it on her hand. She said to Danica: "Press that switch, let me go first, and you will come after two seconds." Phyllis went out for a trip and brought a lot of equipment that could save her life. These things were enough to give her the confidence to make some risky decisions, but Danica was just an ordinary girl. The only magical equipment on her body was the storage ring she gave her. Since that's the case, let yourself explore the way.

"Okay, thank you." Danica said gratefully, and found the switch and planned to press it at any time.

Fortunately, Phyllis did not make any mistakes in his calculations. After the iron door opened, the two girls rushed over one after another. After Danica passed, she stopped for about a second before the door fell heavily.

"Good luck." Danica muttered softly, but it still hurts. She just thought about passing the iron gate as soon as possible. It was not within the scope of consideration of what position to land. As a result, she hit the ground heavily and felt a sharp pain all over her body.

Danica was about to stand up when she suddenly heard a loud bang, and several pieces of debris flew out from the rock wall next to her, hitting her directly, causing pain.

"There is an ambush!"

Hearing Philis' shout, Danica quickly took out a small bottle of green potion and threw it to the ground with force, and at the same time released her only spell: the Light Wind Technique.

Under the urging of the wind, the bottle of potion quickly atomized, and the faint mist quickly spread to the entire narrow corridor. She had practiced this set of movement before, in order to quickly react in an emergency, but she didn't expect to use it as soon as she entered the ruins.

"Mask!" Danica shouted at the back, then began to run away with her head in her arms.

Phyllis was also bent down and looking for a cover. She was stunned when she heard Danica's words, but soon she understood that what she wanted to say was a mask. Danica had said before when she was preparing, some of the potions she prepared were volatile and toxic gases to kill the enemy, but if the battle occurred in a small space, these poisonous fogs would also hurt their own people, so they both prepared a simple gas mask, which was actually similar to an ordinary mask, but it was just a layer of dead stems of the Salo grass soaked in the potion. Danica was probably afraid that the other party would realize that the fog was poisonous.

"Okay, I understand." Phyllis responded, took out the simple gas mask she made from the storage bracelet she wore on her right hand and put it on her face. At the same time, she finally found a half-collapsed platform and hid behind. The loud noise just now was obviously a gunshot, and hiding behind the cover could protect herself well.

After feeling a little safe, Phyllis's tense heartstrings slowly relaxed. Only then did she feel a little uncomfortable and her lungs were vaguely painful.

The potion prepared by Danica was too domineering. Phyllis sighed. She just took a few puffs and had such an obvious reaction. She is an elf, and she also has natural magic accessories on her body. The poison resistance is very high. She is like this, and I guess the other side won't feel very good either.

Sure enough, as soon as Phyllis got up, he heard a series of violent coughs.

The coughing sound exposed the opponent's position. The time for counterattack was already here. Phyllis pulled out her wand and silently recited the spell. A bright white lightning ball flew towards the direction where the coughing sounded.

At the same time, Phyllis saw a large handful of white fine sand flying towards that direction. It seemed that Danica also judged the other party's position based on the coughing sound.

"Ignifying powder? Cough... Cough... Are you planning to kill all of us? Cough... Cough... Dare to use this kind of thing in underground caves." The ventilation of underground caves is limited even if it is good. The violent combustion of ignition powder brings strong lethality and consumes a huge amount of oxygen. At that time, they will die of suffocation.

This sound...

"Wait, this may be a misunderstanding." Phyllis shouted loudly, the other party's voice was very familiar, as if... the voice of that guy, why did he come here?

"Oh, it's you, cough... cough... I didn't expect to meet the elves here..." The other party also heard Phyllis' voice and said in a somewhat teasing tone.

"I didn't expect to meet you here." Before the other party exposed her background, Phyllis quickly stopped the conversation.

"Oh, is that right? Cough... cough... this damn smoke." After a few words, the other party started coughing again.

Phyllis seemed to know the guy opposite, and it seemed that there was no need to fight anymore. Danica put away the ignition stone specially prepared for the ignition powder, summoned a breeze, and blew away the smog.

Only then did she see clearly who was opposite.

It was a dwarf, and it looked less than 1.5 meters, but it was already considered strong and tall among the dwarfs. He was wearing a simple leather armor and holding a hunting rifle in his hand. The hunting rifle should have been a while ago. The wooden handle had very heavy traces of time. Although the black iron gun rod did not have any magic patterns, it gave people a particularly cold and cruel feeling.

"Hello, Philis, hello, this lady." Although the dwarf was quite rough, he was unexpectedly polite, and his behavior gave people a particularly comfortable feeling. The dwarf's voice was a little hoarse, as if it was caused by the stimulation of the poisonous fog just now, but he did not react in any particular way, as if the conflict between them just now did not exist at all.

"Hello, Dulu, Danica, this is Dulu, a friend I know, Dulu, this is Danica, a new friend I just met." Phyllis introduced the two. The words used during the introduction had already shown her relationship with the other party, but Danica didn't understand the words in such social situations, so she just nodded at the dwarf in a ignorant way and said hello.

After seeing the introduction, Phyllis asked the most concerned question: "Turu, why did you come here?"

True did not answer Philis’ inquiry directly, but said: “Phyris, you know that our dwarves like the most besides fine wine and forging is adventure. I am now on a ruins adventure!”

Phyllis frowned slightly and said, "Don't tell me these useless words. You know what I mean. This is not an ordinary relic."

Philes' blunt accusations made a glimmer flash in Trudeau's eyes. He said tit-for-tat: "So what, just because this is not an 'ordinary' ruins, I can't come to explore? Don't forget that the adventure team that discovered this ruins also had members of our dwarves. Why can't I come here?" Trudeau is not a competitive person who cares very much about face, but he doesn't know why, every time he sees Philes, he always feels irritated.

Phyllis, who was choked back, was about to speak when he heard a charming voice coming from behind: "Okay, and Miss Phyllis, you should also remember that there were also our human race in the adventure team."
