In Zhao Xing's second stage treatment, Chuanjie Tower is a key place.

Bowei believes that the Wasteland Era does not have very good means to completely eliminate the true spirit poison.

But there are indeed many ways to do it in history.

Especially some plants have disappeared in the wasteland era, and there is no medicinal materials in the ancient prescriptions now.

In the same example, many natural treasure lands have disappeared as the wasteland spreads.

The Xingyue Spring, which was once located in the Walan Wilderness, dried up in the third era of the wasteland. The condensed spring water inside it was originally a holy medicine for healing.

Since the end of the Five Emperors era, the Medicine King Realm, which has rapidly declined, once had brilliant medical methods.

And the divine thing that has lost its divine nature now

"There is no such era in the wilderness,"

"However, there were many ways to cure me in history before the Wasteland Era." Zhao Xing looked at the list.

"Mr. Ji, are you in Tianshi Mansion? Have you ever heard of Chuanjie Tower?"

Ji Si was pushing Zhao Xing’s flower chair. When he heard the question, he nodded:

"I have heard that Chuanjie Tower is a divine object in history, containing two great ways of time and space, cause and effect. Through Chuanjie Tower, you can even bring treasures back."

Zhao Xing asked curiously: "Is there a paradox? Suppose I took away a divine object from the 4th epoch of the Desolation Realm, such as the Great Yan Divine Soldier of the Red Star Empire. Wouldn't the Empire have no Great Yan Divine Soldiers since the 4th epoch of the Desolation Realm?"

Ji Si smiled and said, "What the Grand Minister wants to ask is, will history change because of this?"

Zhao Xing nodded: "Yes, you have both great ways of cultivating the life and historians. I want to ask what you think of it+

Ji Si said in a slight sense: "I have read the classics of the Tianshi Mansion. From my understanding, the time and space travel of Chuanjie Tower will be discussed in many ways."

"First, it is true replacement. We can bring back treasures from history. This proves that we have really reached the time and space of history through the Chuanjie Tower."

"But it won't let us appear at some key historical nodes, such as going back to the past and killing a certain divine body - this is impossible."

"I just said that Chuanjie Tower is a divine object that contains two great ways of time, space, and cause and effect."

"Since it is a divine object, its power has an upper limit, and it is impossible for the Chuanjie Tower to do anything beyond its power."

"In addition, the "bringing back" function of Chuanjie Tower has the principle of equivalent exchange."

"That is, I will bring back a Taoist soldier of the Realm Star or the Dao Slayer from history. I must prepare a Taoist soldier of the same level and replace it."

"Keep the [critical value] of the present and past unchanged."

Zhao Xing thoughtfully said, "Is the boundary value similar to the spiritual value? The total amount of spiritual value in the past and present remains unchanged?"

"It's okay to say that." Ji Si nodded, "The critical value is the evaluation value of Chuanjie Building itself,

But it's not a simple replacement of spiritual energy."

"I'm not very clear about the specifics, and there is no detailed record of the Tianshi Mansion."

Zhao Xing asked the second question as he followed the first situation: "Even if the spiritual matter is balanced, information is illusory."

"We will also have an impact through the Chuanjie Tower, right? For example, telling the human race the result of a certain battle, changing the past."

Ji Si replied: "This involves the second situation, the one-way avenue in Chuanjie Tower is isolated."

"We can get information from the past, but our information cannot truly fall in history and space.

"

"For example, I went back to the past and wrote a martial art for my predecessors, but I couldn't leave this martial art in the past."

"Because the practice of the Tao is the embodiment of the Tao, my Tao will inevitably not exceed the time and space, the great way of cause and effect contained in the Chuanjie Tower itself. Therefore, I cannot cross the barriers of this Tao."

"On the contrary, I learned a lost martial art from the past. But I can bring this martial art back."

"If I get this technique, it will not have any impact on the past."

Zhao Xing asked in confusion: "Is the replacement of Chuanjie Tower so accurate? Some of the ancient medicines I went to collect have disappeared, so there is no problem with this?"

Ji Che thought to himself, "The cause and effect contained in Chuanjie Tower itself should bear the cost and erase historical errors."

"Theoretically, the treatment plan that Bovey set for Grandmaster is feasible."

Ji Si's answer was not very confident, after all, he was not a god and had never controlled the Chuanjie Tower.

Zhao Xing felt that Chuanjie Tower could not be so perfect. Even if it was a powerful divine object, it would be too powerful.

Too perfect.

If it is really so useful, why didn’t the ancestors of Xuecheng pass it down, but hid it deep in the eighth Dharma Realm?

However, there is no answer to ask Ji Si now, and maybe Bo Wei can't answer either.

The trip to Chuanjie Tower has been confirmed. No matter what you think, this place is the only way to recover, and even the treatment fee has been paid.

There is still a lot of preparations to do before departure, that is, to read history carefully.

Although Ji Si will be accompanied by this trip, Zhao Xing's idea has always been to rely on others rather than on himself.

He is also reading a lot of historical materials.

As a historian, Ji Si majored in professional spells: [Biography], [Ancient Clan], and [Biography]. These are all related to historical figures, mainly reflected in combat effectiveness.

As for the [Ten Tables], it records the major events in the Xuanling Star Domain and its understanding of the Dao of Time.

The historian who majored in [Eight Books] has the lowest status because he has no combat power.

The Eight Books mainly record Taoist rituals, music, music, rhythm, star ephemeris, astronomy, and feudal talks.

Zhao Xing mainly reads books related to [Ten Tables] and [Eight Books], memorizing the historical time, the great changes in the geographical environment, and the territory changes of the Xuanling Star Domain, and some miscellaneous talks.

"Crazy~" Zhao Xing picked up a book called "Tianyou Pinghuai Book".

Pinghuai Book is one of the eight books, Tianyou Pinghuai Book, which means the record of fighting against void rivers and controlling disasters within the territory in the ancient Tianyou Kingdom's history.

Zhao Xing has read a lot of versions, but the Pinghuai Books in different places have different preferences and different levels of details. This mainly depends on the style of the historian.

"The time period recorded in this book is from the 22nd Era in the First World to the 20th Era in the First World, and lasts for 2400,000 Star Years."

"It's quite short in history books." Zhao Xing became interested.

The history of the Xuanling Star Domain can be traced back to the period of the Five Emperors. The ancient kingdom appeared only after the end of the Five Emperors era.

The oldest [Ancient Kingdom] is about 400 years old, connected with the last generation of the Lihuang era of the Five Emperors. It was previously the unified territory of the Five Emperors, and none of the ancient kingdoms have appeared.

The Lihuang era has more than 400 million world star years. The end of the Five Emperors era is the era of ancient countries of chaos.

The Book of Pinghuai only records two epochs, which is already very short. Since the time is short, it will definitely be recorded in more detail.

"In 1389, Tianyou's four suns, the Lixing River changed drastically, with a total of 340 million livable realm stars. The star land was destroyed by the Lixing River. The disaster of the void turbulence affected the 3,250 near-river star areas of the ancient Tianyou Kingdom."

"Well? The Li Xinghe Transformation actually destroyed more than 3,000 star areas. This disaster is great enough." Zhao Xing said intimately.

The river in the void layer is the "Yan" condensed into liquid. It may be spiritual energy or poisonous gas, a mixture.

If it is mostly spiritual energy and has a high stability coefficient, it is called the Void River.

If it is harmful and has a high chaotic coefficient, it is called void turbulence.

Generally speaking, the rivers in the Xuanling Star Domain are stable, and such drastic changes have rarely occurred.

The recent large-scale Void River transformation is the Yueluo Cemetery that Zhao Xing experienced in the "Phantom God Galaxy", which was washed out by the Void River.

However, in terms of intensity, the situation in Yueluo Cemetery is far less than that in Lixinghe.

"In the 1390th year of Tianyou's reign on Siyang, forty-six river generals in the He District, and the Pinghuai envoy were executed--"

"In 1423, after the management of Tianyou Agricultural Supervision, the sudden change in the Lishui Xinghe River still cannot be calmed down, and the source of the radical change cannot be found-""

The Pinghuai Book has a comparison of the territory map. Zhao Xing looked at it and symbolized that the southern part of the territory map of the ancient Tianyou Kingdom was empty by one-third, and the map was dark. This means that a large number of boundary stars and star continents have disappeared, and it is a vacuum area.

Only eye-catching signs were marked on the edge of the disaster area, some representing violent vortexes of void wind, and some are lightning marks, representing terrifying minefields.

The dim starlight is a territory with relatively weak disasters. This situation has not improved at all until the 1550 years of Tianyouli Four Yangs, but has further expanded.

"I didn't expect that the ancient Tianyou Kingdom had encountered such a big natural disaster in the history of the ancient Tianyou Kingdom." Zhao Xing looked at the map of the ancient Tianyou Kingdom today, and compared it, he found that it was about one tenth smaller.

In the southern part of the ancient Tianyou Kingdom, the missing area has become a wasteland and is named the Lishui wasteland.

Obviously, that disaster was not finally saved or restored.

This aroused Zhao Xing's great curiosity.

"The Ancient Kingdom of Tianyou is one of the top ten in the Ancient Kingdom Alliance, and it cannot solve the disaster of the Lixing River."

"What is the reason?" Zhao Xing, as a corporate farmer, was very curious about natural disasters.

Especially the name of Tianyou Ancient Kingdom touched his nerves.

Because in the revised memory, the last Xuanling Dharma Assembly was hosted by Tianyou Ancient Kingdom.

Du Yun also became a genius in the ancient Tianyou Kingdom, including Lao Qing, who had become a god, and the Purple God Mansion also completed the migration.

After continuing to read with questions, Zhao Xing kept turning "Pinghuai Shu" in half before he saw the reason.

The drastic changes in the Lixing River lasted for a whole era, and it was not until the end of the 22nd era of the desolate land that the Jinnong of the ancient Tianyou Kingdom found the cause of this disaster."

"The birthplace of Lixing River is at the 29th thunder of the northern part of Tianyou Ancient Kingdom. The Dasiyuan 'Yuehong Road' discovered that a plant life branch that had never been seen before appeared in the birthplace of Lixing River."
