If Du Yuqi was an ordinary person, he would have fainted due to suffocation, and would have died unless he underwent a laryngeal incision within three minutes. Fortunately, the treatment drug took effect quickly, otherwise Du Yuqi would have had to fumble for a tracheotomy!

The feeling of breathing fresh air was so good that Du Yuqi didn't feel the burning pain in his body until several minutes later. The burning pain unique to burns is a manifestation of damage to nerve endings. After Du Yuqi raised his hand, he found that the burn was quite serious. There was even a black carbonized layer on the surface of the skin, and blood was gushing out of the cracked wounds. The burns on the legs and back should be equally serious.

However, the healing potion that Du Yuqi drank was still taking effect. After treating the burned respiratory tract, the remaining effect was still continuing to act on the burn wound, so Du Yuqi was feeling much better now. He took a few deep breaths, then opened his mouth and said:

"I'm fine."

However, as soon as Du Yuqi finished speaking, he realized that his voice was very weak and hoarse, and he suddenly realized that his vocal cords were also damaged.

Hearing that Du Yuqi's complexion had returned to normal and he could speak, the others breathed a sigh of relief. Only then did Jet frown and say:

"What the hell is that? Have you ever seen a monster like this before?"

Every time he pondered:

"This thing looks a lot like the Burning Hera mentioned in the magic book. This fiery red burning weird skeleton will form a high temperature field around its body, and anyone who gets close to it will suffer continuous burns. However, the Burning Hera sounds very troublesome, but in fact they are not taken too seriously, because most third-level ranged professions can quickly kill them from a distance. The ghosts we encountered are more like a stronger version of the Burning Hera."

"They are man-made!" Xi suddenly said.

Then Xi took out a charred object from his dimensional ring and threw it on the ground. It actually collided with the rock and made a metallic sound. Looking closely, this thing looked very much like an arm bone.

"Pastor Du successfully killed one of the monsters and cut off its hands. When I was leading him away from the battle, I found that the flames on the severed hands had gone out, so I took one back with me."

Naturally, everyone's eyes fell on the severed hand, and they eagerly moved closer to study it carefully:

"Ah! This is a very advanced biomechanical technology. You see, the bones inside are obviously biological, but they are engraved with a lot of spells. And the steel structure is added to the outside of the internal skeleton, which increases the strength of the bones by at least several times!"

"The small holes here should be the secret of their flames! Hmm, I seem to recognize this spell... It is recorded in the Scarlet Book. Hey, what kind of spell is that? I don't think I have ever seen it before."

At this time, Holmes next to him said with a serious expression:

"This spell represents fusion and destruction!! The monsters we encountered should be Crazy Ivan, the powerful biological weapon that was secretly researched by the empire back then! The burning Hera mentioned before was just a failed experiment. They can form a terrifying high-temperature field around their bodies, burning enemies that approach them without any action - Pastor Du and Xi should have suffered from them before, but this is just one of their abilities!"

"And their most terrifying ability is that after being attacked and injured to a certain extent, the self-destruct program in their bodies will be activated, and all their energy will be added to their movement speed, doubling their movement speed. Once they catch up with you, they will trigger a terrifying self-destruction effect, which is extremely powerful!"

At this point, Holmes glanced at Jeter and said:

"As we can see, this Crazy Ivan is made by combining organisms and machines. At that time, the empire reached a consensus that Crazy Ivan's biological form should have a certain degree of intelligence, be found everywhere, and be able to adapt to most environments. At the same time, the most important point is that there must be enough of them! In this way, there will be no need to worry about raw materials when large-scale production is carried out in the future. In fact, there are not many biological species that meet this condition. In the end, goblins were selected. Therefore, the normal form of Crazy Ivan is roughly similar to that of goblins."

After hearing what Holmes said, Duize frowned and said:

"There are at least a dozen Crazy Ivan monsters in here! And we have no way to lure them out and kill them. We can only engage in terrible indoor close combat with them. Are we going to give up here?"

There is no doubt that Duize was very unwilling at this moment! The feeling of being so close yet out of reach had almost driven him crazy.

Du Yuqi stood there and pondered for a while before saying:

"It's too early to decide our next move now. After all, we have too little first-hand information about these monsters. Now that I think about it, my previous injury was an accident. If I hold my breath while fighting them, I will not be powerless. The high temperature area is very tricky, but as long as you make up your mind, it is just tricky. It doesn't make people feel helpless."

"If they are not very intelligent, there are still ways we can think of. For example, we can use my Dimensional Rift to set traps and significantly reduce their numbers. Or we can try to attract their attention and open the warehouse door directly!"

Xi also added at this time:

"From the fact that they don't know how to use the portal to chase us out and attack us, it can be seen that these guys are not very smart. After hundreds of years, they are still alive and can execute orders, which means that most of their body structures should be metal components. If they were mostly biological components, they would have turned into bone residue long ago. So, can we use the program loopholes designed in the mechanical structure to launch a targeted attack on them?"

At this time, Holmes sighed:

“You are too optimistic.”

After hearing what Holmes said, Du Yuqi said seriously:

"Huh? What happened?"

Holmes said:

"I must emphasize once again that the most terrifying thing about Crazy Ivans is not their high temperature fields, but their self-destruction! They are extremely powerful, and when they enter the self-destruction mode, they are incredibly fast, which can catch people off guard. Bloodthirsty cat demons will only threaten awakened masters when their number exceeds thirty. However, as long as the number of Crazy Ivans exceeds ten, awakened masters must be cautious and tread on thin ice!"

Du Yuqi pondered and said:

"If humans want to have enough energy to carry out activities, they must eat, drink water and sleep to support themselves. Once Crazy Ivan is activated, it will be in a high temperature field and self-destruct. The consumption must be not small. They can't maintain this state forever, right? If so, they can only support one or two days at most, right?"

"And these Crazy Ivans seem to be the last resort of the alarm system of this base. When they were not activated, they had already turned into statues. Can they return to the statue form after being activated?"

"Then the question is, if they can enter the statue form, they need to be awakened, so we can directly block the alarm system's awakening mechanism! So everyone doesn't have to be so pessimistic. As the saying goes, the turtle is caught in a jar. Now the other party is the turtle. We can come and go as we please, which gives us an absolute strategic advantage!"

When everyone heard Du Yuqi's analysis, they immediately felt that it made a lot of sense and nodded in agreement. Holmes also felt that his worries were indeed a bit excessive, so after discussing it, they decided that they could wait for two hours before going in to wait and see, and there was no need to take risks. Holmes summoned a summoned creature to teleport in, and if it was not dead after a few minutes, he could go in again to wait and see.
