The rocks of the Grand Canyon are mostly red, and from the bottom to the top, there are rock formations from the Cambrian to the Cenozoic era, with clear layers and different hues, and contain representative biological fossils of various geological ages.

The Colorado River, which flows from the bottom of the Grand Canyon through the Grand Canyon, is a masterpiece of the Colorado River, which originates in the Rocky Mountains of Colorado and flows through Utah, Arizona, and from the Gulf of California into the sea, with a total length of 232o kilometers.

"Colorado" means "red river" in Spanish, which is named because of the large amount of sediment that carries in the river, and the water is often red.

The long-term erosion of the Colorado River, reluctant to rush forward day and night, sometimes open the mountain and split the road, sometimes make way to flow back, in the upper reaches of the main stream and tributaries have carved out 19 canyons such as Black Canyon, Canyonland, Glen Canyon, Bruce Canyon, and finally flow through the rocky Kaibab Plateau in Arizona, there is an amazing stroke, forming this Grand Canyon wonder, and becoming the king of canyons among all the canyons in this water system.

The shape of the Grand Canyon is extremely irregular, roughly east-west, winding like an untamed python crouching on the Kaibab Plateau.

The width of the Grand Canyon is between 6 kilometers and 25 kilometers, and the banks of the canyon are high in the north and low in the south, with an average valley depth of 16oo meters and a valley floor width of 762 meters.

The Colorado River surging forward at the bottom of the valley, forming two mountain walls, a water flow of the magnificence, its majestic landform, vast spirit, awe-inspiring demeanor, strange scenery, the world is unparalleled.

The width of the valley floor of the Grand Canyon is between 2oo~29ooo meters, and as early as 5ooo years ago, there were indigenous American Indians living here.

The Grand Canyon Rock is a geological picture that reflects different geological periods, and its magical colors change under the sun's rays, attracting the attention of countless tourists from all over the world.

After Zhao Liang said goodbye to Zhao Tiezhu, he went straight to the Grand Canyon of Colorado to find the cave full of top-grade spirit stones, if ordinary people went to the Grand Canyon to find a cave, it would definitely be a needle in a haystack, but Zhao Liang is a cultivator, he can fly in the sky, and the degree is not known to ordinary people How many times faster.

Three days later, Zhao Liang appeared in the cave on a cliff in the Colorado River, and the reason why he was able to appear in that cave was because Zhao Liang had a natural perception of spirit stones, after all, he was a cultivator.

After Zhao Liang entered the cave, he couldn't help but be stunned by the scene in front of him, which was densely packed with top-grade spirit stones, at least tens of thousands, or even hundreds of thousands of top-grade spirit stones.

Zhao Liang felt a dry mouth, Nima, are all the best spirit stones in the world here, he inherited hundreds of top grade spirit stones from Long Lei, he felt very awesome, but in the face of the mountains of top grade spirit stones, he felt that he was still shallow.

With such a huge amount of wealth, Zhao Liang naturally took it for himself mercilessly, these top-grade spirit stones, for ordinary people, it was a pile of rags, and for cultivators, it was a huge wealth.

Zhao Liang received all these superb spirit stones in one go, and the original appearance of the cave was revealed, this is a huge cave, the internal space is like an inverted bowl, the roof of the cave is very high, about more than 4o meters, more than 2oo meters horizontally, Zhao Liang stood in it, feeling extremely empty.

Zhao Liang thought about it, and felt that it would be better to practice here first, if he returned to the Massachusetts Institute of Technology now and found Kong Yuzhen to travel through time and space, he would always feel that it was a little unreliable, after all, their time travel device was just an experiment, and if something went wrong, he would be completely finished.

Now, with so many top-grade spirit stones, it is better to improve your realm here, and if something goes wrong in the crossing, you also have the ability to protect yourself.

After Zhao Liang made up his mind, he was ready to attack the consummation realm of the late stage of the Jiedan here.

The Dan period is divided into three stages: Ning Dan, Pregnancy Dan, and Po Dan.

Zhao Liang has reached the realm of breaking the Dan, belonging to the late stage of the Dan, as for the consummation of the late stage of the Dan, that is the personal definition, the Dan has nine turns, that is, after the Dan is broken, it is Ning Dan again, pregnant Dan, and the Dan is said to be a turn, repeating nine times is the Nine Turns of the Golden Dan, the legendary people of the Nine Turns of the Golden Pill are the strongest storage zài in the Dan period, and some of the masters of the Yuan Infant Period who have three turns and four turns are not the opponents of the people of the Nine Turns of the Golden Dan.

The Nine Turns Golden Pill is extremely difficult to practice, every time it is extremely difficult to break the Dan, it not only requires the will of the cultivator, but also needs a large number of spirit stones, if you want to break the Dan, you must use huge spiritual power to break the original Inner Dan again, and then Ning Dan pregnant Dan knot Dan, every time it succeeds, the Inner Dan will be doubled, but the difficulty of breaking the Dan again will be doubled.

Many people in the Dan stage often do not seek to immediately break through to the Yuan Infant stage, but have been staying in the Dan stage, just to be able to practice Neidan a few more times.

The Thousand Madness of Shenlong Island, Fu Jing and the others are all in the realm of Jindan Six Turns, and if they want to break through one layer, it is definitely like ascending to the sky, but immortal cultivators have a steel-like will, and they will not give up until they reach their goal.

The people who have reached the realm of the Nine Transformations of Jindan, except for a few characters in the legend, there are really no other immortal cultivators who can reach it.

Zhao Liang is ready to impact the realm of Jindan Nine Turns here, this cave is an excellent place to cultivate, there are such a large number of top-grade spirit stones in the cave, but the spiritual energy is rarely leaked.

If such a large number of spirit stones were exposed outside, it was estimated that Zhao Liang would be able to perceive it thousands of miles away, and it was because this cave had the effect of naturally isolating spiritual energy that it took Zhao Liang three days to finally find this place.

In the process of the ninth rotation of the Jindan, every time the Dan is broken, the spiritual power of the cultivator will leak out in large quantities, causing a huge waste, and the next time the Ning Dan Pregnancy Pill will consume an even greater amount of top-grade spirit stones.

Very few people are able to practice to the ninth turn of the Jindan, on the one hand, because it is extremely difficult to break the Dan, and on the other hand, the lack of enough top-grade spirit stones is also an important reason.

The best spirit stones of each immortal cultivation sect are extremely important resources, and they will be distributed according to the disciple's table, even if they are excellent disciples, it is impossible to get all the resources, and many times, they can only rely on themselves to find or buy the best spirit stones.

Zhao Liang has no worries now, on the one hand, this cave has a strong effect on preventing the leakage of spiritual energy, on the other hand, there is no need to worry about the lack of spirit stones, hundreds of thousands of top-grade spirit stones, if it is not enough, there is no way.

Zhao Liang simply suspected that all the best spirit stones in this world were in this cave, since he came to this era, there had never been a cultivator, Zhao Liang guessed, there were no cultivators in this era, I don't know what the reason was, when those cultivators left, put all the best spirit stones in this cave, this qiē is a huge mystery, waiting for him to solve.

Even if Zhao Liang wanted to break his head, he didn't come up with a reason, he decided not to think about this troublesome question, now, the most important thing is to be able to complete the realm of the nine turns of Jindan, so that if he goes to find Kong Yuzhen again, he can travel back to the past through time and space.

Zhao Liang made up his mind, so he found a lot of big rocks from outside the cave and blocked the entrance of the cave to prevent any creatures from entering.

When practicing, the most taboo is the disturbance of the outside world, even if an inconspicuous little mouse distracts you, it may make you go crazy, so Zhao Liang is very cautious about this, and absolutely does not allow any accidents, now he can only rely on himself, and no one can help him.

After making all preparations, Zhao Liang sat cross-legged in the center of the cave, took out hundreds of top-grade spirit stones from the ring and put them beside him, he was ready to start breaking through the realm of the second turn of Jindan, if it was placed in the past, Zhao Liang would definitely be very distressed, but now there are more than 100,000 top-grade spirit stones as a backing, there is no need to consider the question of whether the top-grade spirit stones are enough.

Zhao Liang closed his eyes and began to impact the realm of Jindan's second turn.

Breaking through the late stage of the knot pill is the realm of the first turn of the golden pill, Zhao Liang probably consumed 1oo top-grade spirit stones, breaking through the realm of the second turn of the Jindan, the number of top-grade spirit stones required will increase exponentially, at least 2oo top-grade spirit stones are needed.

For Zhao Liang, there was no difficulty in the second turn realm of Jindan, when he absorbed 3o top-grade spirit stones, the original inner pill burst suddenly, and the aura on Zhao Liang's body scattered out, due to the effect of this cave, there was no trace of aura leakage, Zhao Liang first absorbed these spiritual qi, and began to condense the pill again.

This process is relatively long, but Zhao Liang has already experienced the Ning Dan Pregnancy Pill, so he is naturally familiar with it, and it only took two days to condense the Inner Dan again.

Po Dan is naturally the most difficult, the feeling of wanting to crack and not wanting to live is definitely not something that ordinary people can bear, but Zhao Liang has an extremely strong ** and steel-like will.

Three days later, Zhao Liang's Inner Dan shattered again, and he had broken through the realm of the second turn of Jindan and entered the realm of the third turn of Jindan.

If outsiders knew that Zhao Liang had broken through to the realm of Jindan Three Turns in just five days, they would probably have to be scared, this is simply an inhuman degree, dare not be so strong.

After Zhao Liang broke through the realm of the three turns of Jindan, he slowly opened his eyes, he felt that it was necessary to take a rest, the path of cultivation could not be too rapid and fast, and if the degree was too fast, the foundation would be unstable, he did not have any external interference here, he must pursue steady and steady, and he must not be in a hurry.

Zhao Liang adjusted his breathing, slowly entered the ethereal state, and began to adapt to the realm of Jindan's three turns, and after half a day, he slowly opened his eyes, and the realm was completely stabilized.
