"Don't worry, it's not that hard for you. First, as long as you come to Hu Qingniu for a physical examination every year in the future, it will be good for you and me, so why not. Saying that, Lin Tianheng gave Hu Qingniu a look, and Hu Qingniu understood it at the moment.

Lin Tianheng wanted to use some of the Ten Thousand Healing Pills for a long-term experiment to see what kind of Gu worms were contained in it, and whether there was a way to get rid of them.

Now that he had figured out the comparison of the time flow rate between the two worlds, Lin Tianheng only needed to go back to the main world for a short time to smoothly receive the research results of several years or even decades here.

As for who the experimental subject is, in fact, Lin Tianheng doesn't care at all, as long as it is a terminally ill and dying person.

Han Qianye just met this standard, and Dai Qisi still had some value, so Lin Tianheng chose it.

"This ......" Han Qianye and Dai Qisi glanced at each other, but they didn't expect Lin Tianheng to make such a request.

"Will the treatment of the predecessors have consequences?" Han Qianye was the first to react.

"There may be, but it may not be." Lin Tianheng said ambiguously, after all, he wasn't sure how much harm this pill would bring, otherwise why would he need to do this experiment.

"Taking medication may only have sequelae, but not taking medication is a dead end. Both of you are wise people, and I trust you to make wise choices. Lin Tianheng smiled.

"Our husband and wife agreed to this matter, but what about the second condition?" Dai Qisi hurriedly answered, such a simple multiple-choice question, of course she knew how to choose.

"Second, this seat wants you to serve Lin Zifei." Lin Tianheng said.

As soon as these words came out, Dai Qisi and Han Qianye made a difficulty, they had long been accustomed to the free life on Spirit Snake Island in the East China Sea, and now they were unwilling to serve others, and besides, it was really unacceptable to have to be in the same hall with their enemy Fan Yao.

"Actually, this matter is not difficult, the Dragon King only needs to tell you what you know about the situation of Persia and the countries of the Western Regions, and this seat guarantees that you can still stay away from the court and Mingjiao in the future, and continue to live the life of your immortal couple." Lin Tianheng smiled, this is an idle move.

Lin Tianheng knew that after Lin Zifei knew the size of the world, his ambitions were by no means limited to the Central Plains, and Lin Tianheng was also happy to see it happen, after all, the bigger the territory he had won, the more beneficial it would be to Lin Tianheng and the Lin family.

In addition, Lin Tianheng is also a little interested in Persian martial arts, but the mountains are high and the road is far away, and he is too lazy to run in person, so let Lin Zifei worry about this matter.

After a little thought, she agreed to the second condition, that there was no treason for love, since when she left Persia, it was also under the rule of the Mongol cavalry.

The Mongol Empire established by Genghis Khan stretched across Europe and Asia, and was later divided by the struggle for the throne of Kublai Khan's brothers, and was eventually divided into four khanates, the Great Yuan (also known as the Great Khanate), the Chagatai Khanate, the Golden Horde, and the Ilkhanate, of which Persia was within the Ilkhanate's sphere of influence.

What's more, as a holy daughter of the Persian Mingjiao, Dai Qisi has committed the great crime of losing her virginity, and the reason why she pretends to be the golden flower mother-in-law is also to avoid the pursuit of the Persian Mingjiao, once she falls into the hands of the Persian Mingjiao, she will be burned by fire.

In this case, Dai Qisi basically had no psychological pressure on betraying Persian intelligence, and she also wished that the Central Plains Ming Sect could block all the masters of the Persian head religion back and keep her family safe.

As for whether there will be a second Mongol Empire rising from the Central Plains, it is not in Daisis's consideration.

Seeing that the two agreed to the conditions, Lin Tianheng took out one-tenth of the Ten Thousand Healing Pill for Han Qianye to take, and in order to ensure the success of the human trial, Lin Tianheng even entered a pure true yuan to protect Han Qianye's heart.

Facts have proved that the Demon Sect's Ten Thousand Healing Pills are indeed miraculous, and only one-tenth of them cured Han Qianye, who Hu Qingniu concluded that there was no cure.

After using the system to pack a batch of Bodhisattva snakes back to the main world, Lin Tianheng left the Butterfly Valley with the gratitude of Han Qianye and his wife.

When Lin Tianheng arrived in the capital, Lin Zifei personally waited dozens of miles away from the city gate to greet him, and the ceremony was long enough for the emperor to return to Beijing, and the momentum was so great that everyone knew it.

Knowing that Lin Tianheng, the terrifying god of killing, was coming, countless conspirators hurriedly extinguished the careful thoughts in their hearts, and devoted themselves to being the great loyal ministers of the Ming Dynasty.

A few days later, Lin Zifei held an enthronement ceremony, officially proclaimed the emperor, and named the country Ming.

Subsequently, under Lin Zifei's deliberate publicity, Lin Tianheng's image also changed from a blue-faced and fanged devil to a god who rescued suffering, almost replacing Mingzun's position.

Lin Zifei even made a huge golden statue for Lin Tianheng in Da Nei, and asked a special person to worship it day and night.

However, Lin Tianheng didn't know about this, after the enthronement ceremony, he returned to the main world, and before leaving, he made a twenty-year appointment with Lin Zifei.

Twenty years in the Heavenly World, but only ten minutes in the Main World.

In the past ten minutes, Lin Tianheng has not been idle, in order to smoothly receive the materials he and Lin Zifei have set, he can only start digging pits, digging pits in the literal sense.

Due to the limited space of the Lin family's old house, Lin Tianheng could only expand downward, and he condensed into a huge shovel with his strength, and a shovel was dozens of square meters of earth and stone, which was much faster than Lan Xiang's masters, and most of the excavated soil and stones were thrown into the Yitian world by the system, which was convenient and fast.

Fortunately, the place where I crossed was not in the palace, otherwise it would have been quite spectacular if it had rained down in the palace. Lin Tianheng smiled secretly.

Ten minutes is enough time for Lin Tianheng to dig a sinkhole, fortunately, there is no underground water system under the courtyard, otherwise he may be able to dig a natural fountain.

During this period, Lin Tianheng accidentally discovered that the Xiaoao World Passage that had been opened was actually closed, and the name of the world had changed, and it would cost a huge amount of life to open it again.

'Actually changed the name of the world, and this kind of operation?! It turns out that this opened channel may also be closed, could it be that the development of science and technology has led to the promotion of the world? Lin Tianheng was a little puzzled, couldn't this ghost system have a manual.

When the appointed time came, Lin Tianheng turned back to the Yitian world and threw the large amount of supplies prepared by Lin Zifei back to the main world.

These are all war preparation materials, mainly grain, grass and weapons, which are crucial to the next war that the Lin family will face.

After completing the work of the porter of the two realms, Lin Tianheng chatted with Lin Zifei about the development of the past 20 years.

In the past 20 years, Daming has basically not stopped the pace of expansion, but it has been steady and steady, not aggressive, and carefully managed the ground to ensure stability.

First, he went all the way north, killing some of the stubborn remnants of the Great Yuan, and then swept to Liaodong, and now the entire eastern part of Asia is under the Ming Dynasty, and even Goryeo, which has never really been conquered in ancient and modern times, has been included in the territory of the Ming Dynasty.

The Persian Mingjiao got the news from somewhere, knowing that the Central Plains Mingjiao occupied the Central Plains, and had whimsically sent people to "supervise the country", so this group of people and the Holy Fire Order they brought were left in the Central Plains forever by Lin Zifei, who knew their details in advance.

With Dai Qisi's help, Lin Zifei tortured a lot of Persian current information, as well as a lot of Persian unique martial arts, and the date of westward expansion has been set.

In addition to preparing for the westward expansion, the Ming Dynasty is also vigorously developing the shipbuilding industry, Lin Ziwei is in charge of this matter, the fleet has begun to take shape, and will soon set sail to conquer the mysterious territory across the ocean.

"Do you want to go back to Daqi?" Lin Tianheng saw that Daming was developing steadily, and Lin Zifei also had a lot of children, so he couldn't help asking.

"Not back." Lin Zifei replied without thinking, here, he already had too many ties.

After leaving the palace, Lin Tianheng went on a trip to Wudang Mountain.

Hearing that Zhang Sanfeng was in a critical period of retreat, Lin Tianheng did not let Zhang Wuji disturb him.

Now that Zhang Wuji has passed the age and has become the backbone of Wudang, since Zhou Zhiruo has not appeared, he and Song Qingshu have always been in a good state for brothers.

The aging Wudang Seven Heroes have gradually handed over the authority of Wudang to the two of them, Zhang Wuji is loyal and honest, with him to assist Song Qingshu, Song Yuanqiao is very relieved.

Sensing Zhang Sanfeng's breath, Lin Tianheng knew that he was at a critical juncture in the middle stage of the impact on the Grandmaster, and he would never be able to get out of it for a while.

So, Lin Tianheng went to Butterfly Valley again.

Hu Qingniu, who had aged a lot, was overjoyed when he saw Lin Tianheng, who had not heard from him for 20 years, and opened a jar of good wine buried 20 years ago for a long time, and drank it freely.

Hu Qingniu was drunk, but Wang Nangu didn't stop him, but from time to time he asked Lin Tianheng, whose face had not changed, for a way to prolong his life.

Lin Tianheng could only smile, after all, he still couldn't ask for a prescription to prolong his life, Wang Nangu and Hu Qingniu were doctors and poisoners, and there was no shortage of health preservation methods.

After sobering up, Hu Qingniu talked about the research results of the past twenty years, he did accidentally find several things wrong in Han Qianye's brain, presumably there must be Gu worm parasitism, but the Gu worm has not woken up for twenty years, and there is not even a sign of awakening.

Hu Qingniu didn't have a way to deal with this kind of Gu worm, but he felt that the Gu worm was probably dead, and it should be fine.

But Lin Tianheng thought otherwise, how could the Demon Sect's backhand be so simple, the Demon Sect must have a way to revive the Gu worms, but they still didn't know what kind of means this was for the time being.

Lin Tianheng couldn't help but be a little afraid, if the system was not activated, he would definitely take the pill desperately in order to save his life, and then he would inevitably be subject to the Demon Sect, and even become a lackey of the Demon Sect.

Lin Tianheng immediately decided that he must give the Demon Sect a big "surprise" in the future.

In addition to the discovery of Gu worms, Hu Qingniu also has a research result, Bodhisattva.

This pill is made of Bodhisattva snake gallbladder as the main material, supplemented by dozens of medicinal materials, which is more than effective than directly eating raw snake gallbladder.

If it weren't for the fact that the system didn't have the function of bringing people from other worlds back to the main world, Lin Tianheng would definitely pack up all this kind of scientific research talents.

Lin Tianheng returned to the main world with Hu Qingniu's scientific research results, originally he just wanted to wait for Zhang Sanfeng to finish the retreat, so he went to Lao Zhang to exchange his newly created exercises, so many years have passed, with Lao Zhang's wisdom, he must have gained.

But he didn't want to, Lin Junhao didn't go far, and when he heard the sound of Lin Tianheng's "big construction", he ran over to check.

"This ...... What's going on? Lin Junhao looked at the sinkhole full of supplies in the courtyard of the old mansion and was dumbfounded.
