The Vortex Mountains are still the same as usual, and there is nothing out of the ordinary.

After entering the mountain, Calder and the others dismounted and began to walk, because the mountain road was rough.

"Eric, do you know where the Mountain Shield Clan is?"

“……”

Calder turned his head to ask his peers around him, but found that Zhou Dong looked at his pale face, and his eyes were faint like a torch through the skin and flesh of the exterior to see the internal organs, this feeling of being seen through made Calder very uncomfortable.

"I don't know."

"Then why didn't you ask my father to find a guide who knew the way? We don't have time to waste now! ”

Zhou Dong faced Calder's complaints, his scalpel-like eyes did not take any away from this half-elf, and he opened his mouth to continue: "But the dwarves know, I know that there are a few places where dwarves often appear, just grab one and let them lead the way." ”

Calder didn't speak again, and after getting the answer, he quickly turned his head away, walked a few steps faster in front, and his heart was weak, and he didn't dare to look directly at Zhou Dong again.

The other elves were silent with a little impatience, only Zhou Dong walked unhurriedly, occasionally guiding everyone at the fork in the road.

Jane looked at Calder in front of her and moved farther away before she came to Zhou Dong's side and said softly, "Eric, have you noticed that Calder is not quite right?" ”

"People always change, maybe they grow up." Zhou Dong smiled lightly and didn't say much, although he showed a deep interest in Calder as if he had changed people.

Jian pestered and asked a few words, and found that Zhou Dong still didn't eat oil and salt, so he couldn't speak at all, so he could only give up.

Although Calder had said something that made her angry in the morning, Jane cared about the young man who had cultivated some affection before, but only to the extent that it was a little favorable.

According to Zhou Dong's guidance, everyone found several dwarves not long after.

However, the dwarves didn't care to answer their questions or lead the way right now, because they were fighting.

Their opponent is a mountain troll.

"Mountain trolls are all over the world of Alberon and the world of Faeron, the world of Alberon is a high-magic world with a high degree of combination of magic and society, with magic-driven carriages, magic lamps, magic airships and other common magic tools that can be used by workers, peasants and merchants, which is quite different from the European medieval world background of the world of Feron.

The massive creature has thick gray skin and rough troll facial features, and its arched back and ape-like walking posture show off its massive size and the power of its giant fist.

Giant mountain trolls are the largest members of the troll family, they usually live near the top of the mountain range, and only leave their nests when foraging for food, like other trolls, mountain trolls have a voracious and exuberant appetite, mountain trolls are rarely encountered alone, and out of their cruel bestiality and bully the weak, they will sometimes manipulate giants, orcs, and trolls smaller than them.

Despite the giants and orcs doing their best to please them, the slow-witted mountain trolls will only eat any creature that doesn't fulfill its too rudimentary commands.

A typical mountain troll stands about five meters tall and weighs two tons, and has no concept of fear or caution, and when they see something they want (usually something they want to eat), they will grab it and kill anyone or anything that gets in its way.

The mountain trolls of Faeron usually inhabit the mountains that surround Harua and the smaller mountain ranges that traverse Faeron, and the Vortex Mountains are no exception. ”

Seeing this troll teasing a few dwarves like an adult playing with a child, Zhou Dong was not in a hurry to help, and still had time to use his profound knowledge to answer questions for Jane beside him.

Not to mention that Jane had a ripple in her eyes when she heard this, Calder and several elf compatriots looked at each other and rushed up to help.

Strange to say, Jane watched Calder and them rush forward, each with a short sword and two blades, or a bow and arrow, but they were all like the dwarves' axes and hammers, and they finally fell on the troll's tough skin, and some blood came out, but it was only the time to breathe, and the troll's injuries were healed.

Curious, Jane turned back to her companion and asked, "Eric, how is this troll completely unkillable, but it's the same as in the adventure stories I heard in my childhood." ”

Zhou Dong organized his words, and while paying attention to the battle situation over there, he replied in detail: "Because of the regeneration ability, the talent of trolls, but all trolls have a very strong ability to regenerate limbs, as long as their heads are not chopped off or their weaknesses are discovered, they can quickly recover all injuries, even if they are cut in half from the waist down, and then cut off their arms, they can heal on their own in less than half a day." ”

After hearing this, Jane confirmed what she saw in front of her, and remembered that she was easily stunned by the assassin in the hotel bathroom that day, and couldn't help but turn pale, and sighed: "I really envy them, they are born with such strong abilities." ”

As soon as she finished saying this, she heard Zhou Dong's sneer.

"Jane, you don't need to envy them, do you know what price they paid for this super regeneration and self-healing ability?" Zhou Dong used to be fifteen or sixteen years old, he once caught a little troll and did an experiment, at that time he couldn't deal with the big troll, he studied for a few months, the experiment process was of course quite cruel, but in the end he let it go.

Jane's curious gaze came over, and Zhou Dong didn't sell it, and continued: "Let's talk about the root of the troll's regenerative ability, you can understand it as a special element that can be secreted by their bodies, this element has the effect of deformation simulation, for example, if the finger is broken, a large number of this regenerative element will gather at the place where the finger is broken, and then transform into the element of the broken finger, such a process is the mystery of regeneration." ”

The element that Zhou Dong said actually refers to cells, and the regenerative ability is the ability to express a certain part of the genome, and the form of expression is to be able to quickly and in large quantities of energy in the body to produce this kind of cell when injured, this kind of cell has the ability to simulate all the cells in the body, such as brain cells, bone cells, platelets, white blood cells, etc., and in general, it is the popular muscle fibers, fingers, eyes, etc.

"Then Jane, think about it, why are trolls generally so low in IQ?" Zhou Dong threw out a question, hoping that Jane would be able to discover and explore the principle of this problem curiously because of his way of thinking.
