"Ancient Teleportation Array?" Zhang Di frowned, looking left and right at the huge magic array, although he couldn't understand the mystery of those formations, but with some rough formation knowledge that Zhao Danian had taught him, he could still see that this was a teleportation array.

However, the arrangement of this teleportation array is too complicated and profound, if the complexity and level of the teleportation array that Jin Ruolin teleported away before was level 1, then this is enough to be level ten!

In addition to one main array eye, there are also eight secondary array eyes, which are linked to the main array eye in some esoteric way, forming a kind of cascading pattern.

Zhang Di looked at it for half an hour, and then he desperately saw the nine-array eye structure of the first master and eight pairs, he was already tired and dizzy, he couldn't help but close his eyes, and sighed: "What a powerful ancient teleportation array! I don't know who laid it down, and what is its function?"

For a while, my heart was itchy and scratchy, and I wanted to activate this ancient teleportation array, and teleport out through it, maybe I could achieve ultra-long-distance teleportation across continents!

But this thought was just a flash, he calmed down but shook his head, not to mention that it is extremely risky to rashly use such an ancient teleportation array, let's just say that the drive of this ancient teleportation array will cost a lot of money, I am afraid that it will take all the ten thousand spirit stones in this entire cave to drive it, right?

What's more, Zhang Di didn't know if this Ancient Teleportation Array was still safe and sound, if something went wrong, it would be extremely bad to pass himself into the space-time rift!

I remember that Zhao Danian taught him at the beginning, saying that the formation is one of the most mysterious knowledge in the world, and it is to simulate the rules of heaven and earth in a way that humans can master, and the teleportation array involves the mysteries of space. Naturally, if something goes wrong, people will be transported into the rift of time and space.

Because this world is not the only world, but is divided into a small world, a medium world, and a large world. and oversized worlds.

The human realm in which human beings live is only one of the countless small and medium-sized worlds, and the demon realm where the Heavenly Demon is located is a higher level of world. It is called the Great World, and the super-large world above is the Immortal Realm, which is the world where true immortals exist.

The connection between the world and the world is separated from each other through the space-time valve, but it is not absolutely impossible to communicate, for example, this time the heavenly demon descended on the human world is a kind of space-time tunnel through which it passes. And between the space-time valves is the space-time turbulence, and ordinary people will be torn into powder by the power of space-time immediately when they enter, and they can't even exist for a breath.

Some of these ancient teleportation arrays, world divisions, space-time tunnels, and turbulence came from Zhao Danian. Part of it comes from Zhang Di's extensive reading in the Zongmen Library Pavilion. Because all immortal cultivators, in addition to increasing their own cultivation, the more important thing is to understand the existence of the world, so that they can better realize the Tao.

It is said that after cultivating to an extremely high and profound realm, this world will not be able to accommodate immortal cultivators, but will be raised to a higher level by the power of the upper realm, that is, the so-called - Ascension!

Therefore, what immortal cultivators dream of is to ascend, and they will get out of this sea of suffering and come to a wider area. A better new world.

At this time, Zhang Di recalled this, not only was he fascinated, but his eyes flashed with brilliance, and he said to himself: "This ancient teleportation array involves the secrets of the world. If I am determined to cultivate immortals, I can't help but crack the secret of this teleportation array. Although my current realm is very low, my strength is not enough to drive it. But I might as well copy it down and study it later. I'll figure it out someday!"

I was in high spirits, and I just did it. Zhang Di took out pen, ink and paper from the storage bag, traced and drew on the complicated ancient teleportation array, tossed for most of the day to get it done, and then breathed a long sigh of relief and put the copied drawings into the storage bag.

At this time, he was not tired, but became energetic because of his excitement, and turned around to study the skeleton again, because his subconscious told him that this skeleton that had been sitting here for an unknown period of time was only afraid that it had something to do with this ancient teleportation array, if it proved to be true, then this skeleton would be terrible, and it was very likely that it was an ancient immortal cultivator.

Zhang Di first blew off the dust on the bones, and then carefully looked at the bones, only to see that the height was about five feet, the bones were thick, and the width of the hip bones was not very large, so he nodded and said: "It seems that this is a man, with a medium to tall stature, and an extremely strong body." ”

In order to practice killing skills, he went to the cemetery to dig graves and study the structure of various human bodies, just so that he could hit the vital point with one shot, so he was also quite proficient in studying bones, and could basically tell various situations in a person's life.

When he had finished his inspection, he tore off two pieces of his garment, put them on his hand to protect them from uncleanness, and then picked up the bones and looked at them with his hands.

He looked at his teeth first, and according to the degree of wear and tear, as well as the degree of bone development, he couldn't help but be taken aback, and then nodded and said, "This person is about three hundred years old, and he can live for so long, at least he is a monk in the Jindan stage!"

Originally, every time a cultivator broke through a layer of the realm, he could induce the Heaven and Earth Yuan Qi to cut down the body and cleanse the marrow, increasing the longevity of the Qi refining period by 50 years, the foundation building period by 150 years, and the Jindan period by 500 years.

Therefore, this person has a life span of 300 years old, and his bones and teeth are extremely strong, so he should not be a monk in the foundation building period who has entered the last years, but the golden pill period in his prime.

Thinking of this, Zhang Di secretly said suspiciously: "The Jindan period monk who was in his prime died here, is it a vendetta?"

So the bones were examined closely, but nothing unusual was found, not even a crack in the bone.

Zhang Di tilted his head and thought for a moment, then simply fought to aggravate the injury, his eyes were instilled with a look at the Qi Technique, and the entire skeleton was swept from head to foot, and his eyes suddenly lit up.

He resisted the feeling of wanting to vomit blood, reached out and grabbed the thick thigh bone of the skeleton and pinched it, crushing it with a click, only to see that the thigh bone revealed a pitch-black color, and it also emitted a strange smell, which made Zhang Di's mind dizzy when he smelled it.

"It's not good! it's highly poisonous!" Zhang Di's face changed greatly, and he hurriedly took a few steps back, sat down cross-legged, and drove Taiyi Aoki Gong to expel the poison, and it took a long time before he breathed a sigh of relief and returned to normal.

He couldn't help but be shocked, this poison has been so long, I am afraid that tens of thousands of years have passed, and there should be little effect left, but just smelling it makes people dizzy, can you imagine how terrible it was back then?

It seems that this Jindan monk was poisoned by this poison, and somehow escaped here through the teleportation array, but he died of poison.

After roughly figuring out the cause of death of the skeleton, Zhang Di temporarily took care of it, but at this time, he was worried that the poisonous gas would hurt his body, and it was inconvenient to continue the investigation, so he returned to the outer cave, ate Linggu and drank water, and slept well.

After resting for a few hours, his mental and physical strength had recovered a lot, and then he re-entered the inner cave, intending to continue yesterday's exploration. (To be continued......)
