This ancient world, which seems to be underground, or in the midst of a volcano, has always been full of mysteries for Merlin. Let's not talk about the reason for the formation of this underground world, the reason why it can always exist and always exist secretly, and so on, which are related to the most fundamental mysteries. Light is why there is a light source in this world, and it is a light source similar to the sun, and the most important thing is that there is a daily schedule like the sun rising and the moon setting......

That question alone was enough to puzzle Merlin.

Looking at the "stars" that shimmered in the dark "sky" of the "night", and looking at the "moon" that was like a full moon releasing bursts of soft light, Merlin completely gave up his plan to explore this ancient world, and decided to let it be...... Just let yourself be a fool who doesn't know anything......

At Merlin's side, the fossil pterosaur that had always been interested in Merlin's "fine skin and tender flesh" was snoring and falling asleep.

There is a foreign saying that says: You can't become friends without a few fights...... Well, that's pretty much what it means anyway. And for Merlin and the overlord of the ancient sky, after several days of desperate chases, an aerial encounter with Dragul, and then a series of "ancient Pokémon ** experiments" conducted by Merlin in the name of healing, there is a trace of affection and a little inexplicable friendship between these two guys.

Especially under the premise that Merlin deliberately enveloped the fossil pterosaur, the relationship between one person and one ancient creature was very warm, and it quickly warmed up and became familiar. By now, the fossil pterosaur had simply regarded Merlin as a friend of the other race.

Merlin's deliberate friendship with fossil pterosaurs naturally has many considerations and needs. First of all, the newly evolved Dragu needs an opponent who also occupies the air home field as a whetstone to hone his air combat skills and tactics. Merlin's other companions also need a guy with skilled aerial combat skills and experience as the object of actual combat drills, helping them quickly erect a ground-to-air combat mode and accumulate experience.

And these battles, in addition to being very helpful to Merlin's companions, are also a very new mode and experience for the fossil pterosaur. For the ancient beast that was born to fight for survival, this kind of actual combat drill for the purpose of training, more like playing and playing, was something it had never experienced. Since the fossil pterosaur grew up, mastered the basic hunting skills, and left its parents, all the battles it has experienced have been life-and-death battles, whether it is hunting for food, or fighting with its own kind for turf and mates, it has never been such a point-to-point battle. So, the fossil pterosaurs were also very interesting when they were engaged in these training battles. And in the non-stop actual combat exercises, it also learned a lot of modern combat modes and experience from Merlin and his partners. Compared with the hunting instinct that he has inherited since ancient times, it has also made the technical and tactical level of the fossil pterosaur rise by leaps and bounds.

In addition to being a rare opponent, the fossil pterosaur also has other roles for Merlin.

As an indigenous to this ancient world, fossil pterosaurs are very familiar with the geography and topography of the ancient world, and they also know the distribution of products and specialties in the ancient world. And it knows all the dangers and traps that existed in this ancient world. With this free guide, Merlin can navigate the ancient world without hindrance. Not only do you not have to worry about encountering an unmanageable crisis, but you can also harvest some products from ancient times as your own collection.

It's just that because the time gap between ancient times and modern times is too long, it is still unknown how much actual value and application scope many ancient plants or other resources have in the present world, and Merlin needs to slowly explore and experiment.

And as the most important reason why Merlin deliberately wooed the fossil pterosaur, that is, Merlin also had the idea of recruiting and subduing this ancient air overlord. It was only because the gap between the environment of the ancient world and the environment of the modern world was too great that Merlin gradually dispelled the idea of abducting and taking this fossil pterosaur. Instead, find a different path.

The oxygen content of the ancient world, the specific gravity of various trace elements in the air, the content of various trace elements contained in plant fruits, and even the amount of minerals contained in water bodies are completely different from those of the present world. Merlin, as a modern human in every sense, and Merlin's companions, as modern Pokémon in all senses, are actually very hard, tired, and even dangerous to live in this ancient world.

Merlin still has some modern high-tech equipment that can help him breathe the air of the ancient world relatively smoothly, while Merlin's companions can only rely on their own physical resistance, at most supplemented by the application of some superpowers, to barely maintain their basic needs and wear and tear in the ancient world. This is also the most important reason why a fossil pterosaur can smash Merlin's team into disarray. It's not that they can't beat a "merely" fossil pterosaur, but in this ancient world, which is completely different from the modern world, they can only exert three or four percent of their strength at most, which is really not enough to collide head-on with the fossil pterosaur that occupies the home field advantage and space advantage.

And with the help of many "** experiments" secretly conducted on fossil pterosaurs in the name of treatment and rehabilitation, Merlin also came to some interesting conclusions.

For one, if he brought the fossil pterosaur to the real world like this, the fossil pterosaur would definitely suffocate to death, and the speed of this suffocation would be very rapid. Because the oxygen content of the air in the modern world is simply not enough to support the breathing of fossil pterosaurs. And if the fossil pterosaur was lucky enough not to suffocate quickly, then it would also inhale a large number of chemical element molecules and excess trace elements in the modern world during the subsequent breathing process, resulting in rapid poisoning and then death. Because it was in the ancient world, it had no ability and physique to deal with those chemical elements and excessive trace elements.

Second, if Merlin brought the fossil pterosaur to the real world and solved the first breathing problem to keep it alive, then the second problem will follow, the fossil pterosaur may not be able to fly in the modern world. The air velocity and intensity of the modern world are far inferior to those of this ancient world, and the fossil pterosaur's flight mode is mainly based on the wind. Once it reaches the modern world, the currents that aren't big enough to support the weight of a fossil pterosaur can't lift it up and let it soar through the air again.

Third, if Merlin brought the fossil pterosaur to the real world, and solved the problem of breathing and flight with the help of God, then the third problem will immediately be in front of Merlin, that is, the food and water problem of the fossil pterosaur. Fossil pterosaurs could eat modern food, whether it was raw, frozen, or specially prepared feed. However, if you eat it, it can cause severe diarrhea, indigestion and even food poisoning...... Fossil pterosaurs can also drink modern purified water or other similar water beverages, but can also cause severe diarrhea and other symptoms when consumed......

In fact, this problem also bothered Merlin and his modern companions, once they drank the water of the ancient world and ate the food that could be eaten in the ancient world, they would also have adverse reactions such as diarrhea, vomiting, indigestion and even poisoning. And that's just a small dose. Merlin believed that if they ingested large doses of ancient ingredients or bodies of water, there was a high chance that their immune system would collapse and they would die quickly.

Because the microbial environment and viral diseases in the ancient world and the modern world are completely different, they do not have the corresponding antibodies and coping methods, once they are invaded by these completely unfamiliar things, then it is the end of direct death. And it can be very quick and painful.

After clarifying these points, Merlin had honestly put away his plan to take the fossil pterosaur, and at the same time, he had honestly put away the idea of staying in the ancient world for a long time. In the past few days, Merlin has been working with the fossil pterosaur and Dragoo to find a "passage" to the real world, preparing to leave this ancient world as soon as possible.

Thankfully, Wizier was able to teleport back to the modern world, and was able to find his way into the ancient world through the location where Merlin had fallen into the Ancient World. Just this morning, Merlin, the Fossil Pterodactyl, and Dragu had managed to locate the gap between the dome in the "air", where Merlin had fallen into the Ancient World, and on a sharp rock there was even a fragment of Merlin's sacrificial tracksuit and his blood that had long since dried up.

Now, the question before Merlin is how he can return to the modern world through that passage.

It was impossible and unrealistic to climb with bare hands, the passage was winding and deep, and the distance in a straight line might not be very long, but the actual distance was enough to discourage Merlin. Merlin is only in good physique and more agile now, not a barbarian who has evolved into a monkey monster.

Besides, Merlin's superpowers still have to be suppressed even in the passage, so there are many problems with the help of superpowers to help pass through the passage, which is not a suitable choice.

And with the help of partners, it seems that the only feasible way to pass. But how to use it, that also needs to be thought through.

There was no strong man among Merlin's companions who could carry or carry, carry, or hold Merlin through the rock wall passage, and according to Vizil's investigation feedback, there were many places in the passage that were so narrow that only a thin and dry guy like Merlin could barely pass through. Moreover, the hardness and structure of the rock wall are very strong and solid, and there is no possibility of forcible destruction or widening.

"At the moment, the only difficulty is that the superpowers of a few of you are not enough for me to climb to the right position......" With his head resting on his arms, staring at the "sky", his gaze swept back and forth between the "stars", Merlin said to himself: "After a certain position in the passage, the restraint on my superpowers will definitely disappear, the key is where is the specific location of this position...... The closer I get to this world, the more likely I am to succeed in escaping this ancient world. ”

"But you still have to prepare for the worst...... If you are not afraid of 10,000, you are afraid of what if, if this restriction is very close to the modern world, then it will be dangerous......"

Just as Merlin was muttering to himself, a huge roar suddenly erupted in an open clearing in the distance, and then the earth trembled, and the smoke of gunpowder flew all over the sky, and the ancient creatures who were awakened by this loud noise and tremor let out their own roars and shouts, and for a while, the entire ancient world was boiling.

"What's going on!?" Merlin condescendingly looked at the place where the explosion occurred, "At this level, it should be a special force fighting!" ”
