From Yili to the capital, Gu Jia and his entourage walked by horse for more than a month, leaving in early April last year, and now it is March of the following year, and eleven months is the longest day in Gu Jia's life.

The wagon creaked, and there was nothing else on it, four boxes of books scoured all over Europa, and the ashes of fourteen frontier soldiers.

Jiang Tao, the small flag officer, died in battle on the way to retreat, and there was no chance to find the corpse.

The group did not enter the capital, but went straight to the west mountain along the asphalt path from the capital to the west mountain.

At the foot of Xishan Mountain, Liu Hongji, Xu Ji, Qi Yuangong, Song Yingxing, and the students of the Wutang have been waiting for a long time.

"Coming back?" Gu Jia got off the horse, and Liu Hong gradually stepped forward and said calmly with a smile.

"Gu Mou is fortunate not to be dishonored!" Gu Jia bowed to Liu Hong.

Although the question and answer are brief here, a thousand words are hidden in it.

"Old Gu, you've lost weight." Liu Hong gradually patted Gu Jia's shoulder, and the belt gradually widened to say that's what he said.

Gu Jia has only just turned forty, less than a year, and her cheeks are deep, even the hair on her sideburns is white, and her long hair is messy on the gray-black collar, interpreting what it means to have gone through the wind and frost.

"Solve thousands of households...... He was killed in battle, along with fourteen other border brothers who had traveled all the way west, and they ...... They were all dead, Gu was incompetent, and only brought their ashes back. ”

Gu Jia's sunken eye sockets were bloodshot, and he said in a trembling voice.

He will never forget the night on Mount Kilb, that night of cold, hunger, heavy siege, hopelessness, and torture, it was the soldiers of the border army who sacrificed their chances of survival and gave them the only warm clothing.

"I know, I know, they will not die in vain, I will make the Rakshasas pay a thousand, ten thousand times, I will kowtow to their dead brother to apologize, and then let him go to their God in fear, I swear."

Liu Honggradually didn't know how to comfort Gu Jia, who was extremely depressed, and the three surviving border soldiers behind Gu Jia who were also thin and unseemly.

For a moment, he felt that he was still one of the dozen good soldiers, if he didn't fix this moth and didn't let Gu Jia go to Europa, then all this might not happen.

"It's good to come back, it's good to come back, don't stand here, walk back and say! Go back and say! Qi Yuangong took Wu Peng's arm and persuaded him.

"It's Lao Gu, I haven't seen him for a year, let's go, the banquet in the martial arts hall has been arranged, let's get drunk tonight." Xu Ji, the head of the College of Engineering, also pulled Gu Jia with him, and the group walked towards the lecture hall.

In the lecture hall of the martial arts hall, the dishes were served one by one, but there were not many people at the table, and the four boxes had been opened.

Liu Hong gradually picked up a book and opened it and read a few pages, his brows furrowed.

It's all languages he hasn't seen, and occasionally one or two books seem to be in English, but his English is just like that, nodding and choking and shaking his head, it's okay, plus the English at this time is very different from later generations, all of them are like heavenly books.

"Looks like these books have to be translated!" Liu Hong gradually put the book on the table and said.

"Yes, my lord, these books include astronomy, mathematics, philosophy, medicine, theology, and engineering, but it seems that the level of technology on the Europa side is not as good as that." Speaking of the second half of the sentence, Gu Jia also lowered his voice, probably because he was afraid of the feelings of Tang Ruowang and others.

But Europa's bloodletting therapy really shocked Gu Jia, according to the logic of the Europa people, all diseases can be bloodletting, and blood is the foundation of the body, which is completely fantastical.

Liu Honggradually grinned when he heard it, he knew about phlebotomy in Europe, not to mention that it was now the seventeenth century, even a century and a half later, phlebotomy was still popular in Europe.

As far as he knew, Washington, the founding father of the United States, died of bloodletting.

That day, Washington occasionally felt cold and uncomfortable, so he asked the housekeeper to let him bleed, but in the early morning of the next day, not only did he not get better, but he began to have a fever, difficulty breathing, and cold sweats, so he had to call a doctor named Craig to see him.

Dr. Craig began to bleed without saying a word, and prescribed him medicine: a large bowl of an indescribable liquid mixed with butter, honey, and vinegar.

Washington drank and coughed until ten o'clock in the morning, Craig saw that this was not good, and had to bleed, and in two days Washington drank three bowls of unknown liquid, and bloodied four times, and at ten o'clock in the evening, he finally succeeded in letting himself die.

This story tells us that medicine should not be drunk indiscriminately, blood should not be left indiscriminately, and if you do not do it, you will not die.

Liu Hong gradually knew that Europa's medicine was not very good, at least not very much, and the development of technology was sometimes uneven.

For example, in the Mayan civilization in the Americas, astronomy has obviously reached its peak, but the wheel has not even been invented mechanically, and the warships of the Europa people can already be equipped with a hundred guns, but there is still a ridiculous treatment of bloodletting in medicine.

Despite this, Liu Honggradually still regarded these books as treasures, and he did not want to learn from Yi Yi to control them, but they were all-encompassing, and they were the epitome of all walks of life in Europa.

Not to mention anything else, Europa's military system and battleship classification made Liu Hong gradually interested.

"The translator is easy to say, my lord, let me introduce you to these priests who have come to Daming from thousands of miles away." Gu Jia pointed to the five priests at the table.

"This is John Tong, a Jesuit missionary and Catholic Jesuit monk from the Holy Roman Empire, fluent in four languages, and highly accomplished in theology, philosophy, firearms, etc." Gu Jia focused on John Tang.

"Welcome to Daming!" Liu Hong gradually stretched out his hand and smiled.

He is still familiar with this person, and those who have read Lu Ding Ji know that when Kang Mazi recovered Taiwan, there was always a foreigner named Tom Mafa standing behind him, and this person was the main force responsible for developing artillery for Kang Mazi at that time, that is, Tang Ruowang in front of him.

Tang Ruowang was stunned for a moment, as if he was surprised that Liu Hongjian was familiar with the etiquette of their country, and immediately shook hands with Liu Hongji.

"It's an honor to meet you, Your Highness the County King!" After Tang Ruowang let go of his hand, he stroked his chest with his right hand and bowed to Liu Hong.

He was a German and the only one of the few present who claimed to be the Holy Roman Empire, as only Germans considered themselves to be the most orthodox descendants of the HRE.

On the contrary, although many countries in Europa were nominally subordinate to the Holy Roman Empire, they have now experienced thirty years of war, and many principalities have long since broken away from the rule of the Holy Roman Empire.

"This is Hoffmann Jüller, from Austria, a Jesuit monk." Gu Jia continued.

"Welcome to Daming, if you need anything, just say it." Liu Hong said politely.

Yu Le seemed to be a little excited, he and Tang Ruowang had been in Daming for many years, so they naturally understood what Liu Hongjian meant.

"We need a church, Your Highness." Yu Le stroked his chest and saluted, and then said bluntly.

He traveled thousands of miles to return home and from Europa, and went through a lot of hardships to bring the Gospel of Jesus to Daming, and of course, for his personal honor - if he could build a great church in Daming and spread the gospel of God, the Pope would definitely receive him personally and promote him to bishop or even cardinal.

He was too impatient, or too direct, and suddenly made Liu Hong stunned for a while.

"No problem, this king promised you, and he will definitely help you, and the church will start construction in the spring!" Liu Hong gradually forgave this straight man-like guy, and he knew in his heart that Europa people have never liked to be polite.

For example, if he tells you that you are so handsome, if you politely say where and where, he will definitely be confused, and then stammering to tell you that his nose is handsome and his mouth is also handsome.

"This is Oakes, from Billy, my lord, and he doesn't speak yet." Gu Jia pointed to one of the three priests who had been abducted from the church.

……

"Who is this kid?" Liu Hong wanted to ask early, and said in his heart that he had traveled so far and brought a child over.

"His name was Isaac, Isaac Newton, and he was an abandoned child, and when I saw that he was pitiful, I brought him back." Gu Jia said with some embarrassment, this kid didn't cause him less trouble along the way.

But who knew that Liu Honggradually was stunned after only listening to the first half of the sentence.

"Lao Gu, wait a minute, what do you say his name is?" Liu Hong gradually pointed to Newton, who was a little bit of a little bit of a little bit of a thing.
