The layout of the "Pharmacology" bookstore is relatively simple, with an agarwood bookshelf standing on three walls, each bookshelf has four layers, and four books are placed on each floor.

"One Qi Pill Technique, Strange Grass Bible, Heavenly Xuan Pill Book, Five Poison Books, Soul Snatching Incense Secret Alchemy, Silence Fog Shaft..."

Xi Xiao swept the "Body Protection Secret Refining Formula" for refining body protection pills, and opened it to take a look.

To refine the body protection pill, you need to prepare ten drops of Biluo dew, seven coins of Chiyun Baowei, one flower of Fanmo, two plants of tiger and leopard grass, three coins from Huolin, and one dragon fruit.

First use toad wood to burn the Dan furnace, and after half an hour, put in tiger and leopard grass and dragon fruit, refine it with exercises, and after another stick of incense, put it in....

Xi Xiao didn't know any of the herbs and treasures in the book, let alone refining them one by one, and for the first time, he intuitively felt the profundity and mystery of the elixir.

"Shangqing disperses the Yuan Fang. It seems that this is the book that Nishitaki Luo reads. Xi Xiao picked up the prescription and took a cursory glance.

This medicine is in powder, colorless and tasteless, dissolved in water, mistakenly take this medicine, after a cup of tea time, the medicinal properties arouse the inertia of the essence of the sea, within half a day, the combat power of the user drops to three percent, and can gradually recover after one day.

Putting the Shangqing Scattered Yuan Fang back in its original place, Xi Xiao continued to scan, and finally read the "Refining Yuan Danben" on the third floor of the second bookshelf.

To Xi Xiao's disappointment, the celestial treasures required for refining the Yuan Pill were even more complicated, with a total of eleven kinds, and the preciousness of each medicinal material was above the Body Protection Pill, and the refining requirements were extremely harsh, which completely shattered Xi Xiao's illusion of refining it by himself.

"If refining Yuan Dan is so easy to obtain, wouldn't the entire Dragon Palace be all about the King of the Sea Realm. Xi Xiao laughed at himself. And walked out of the five-car pavilion.

A month later, Xi Xiao came to the Rhino Grant Courtyard as promised, and went straight to the living room, where he did not see the Conferon himself, but only his housekeeper.

"Please ask the Commander-in-Chief to take a bath and change clothes later, and tell me to serve tea first. The butler said respectfully.

It wasn't until half an hour later that the sound of the professor's footsteps gradually sounded, and he slowly walked out from behind the screen.

Xi Xiao raised his eyes and was really taken aback.

At this moment, where is the usual unkempt and untidy teaching!

I saw that the person who came was wearing an orange embroidered cloak, his hair was coiled up, his eyes were bright and resolute, and his goatee was neat and straight. It looks like a fairy wind.

Xi Xiaoleng was stunned for a moment, "Grant, you..."

"What looks?!, take a good look. The rhinoceros interrupted Xi Xiao and made a disdainful expression.

Xi Xiao took a closer look, and the teacher was wearing the orange capes worn by the respected teachers when the students competed.

"Are you honorable?!" Xi Xiao was a little uneasy.

"Of course, it's just that over the years, the Wang Yuan has been withering day by day, and the old man is a defense stream mentor, so he can only serve as a part-time teacher... Hey.."

"That holy grant is you too?!" Xi Xiao wondered.

"Ahem. . . Cough.. That's not it, there are only two people in the Dragon Palace, the Dragon King and the Protector of the Country, and they can be personally guided by the Holy Grant, that's a chance. ”

"Of course, I didn't mean to hide it from you, but the time was not right. ”

"If I can't be a teacher, I'm afraid I will never be your honorific status, right?" Xi Xiao said indifferently.

"Perhaps, so. ”

"Seeing that you are already in the Shallow Sea Sevenfold Realm, presumably the refining Yuan Dan has been completely refined, and I have some instructions for you to come here today. ”

"We must not slack off in the cultivation of the Closed Qi Purifying Pulse Technique and the Na Yuan Technique, and at the moment, we should focus on stabilizing the Sevenfold Realm, and make every effort to cultivate the Closed Qi Purifying Pulse to the twelve cycles of the whole body. ”

"The cultivation of the veins can be described as endless, and when you enter the deep sea realm and complete the twelve cycles around your body, you can cast the body of a rock. ”

"Yuanjia Tiangang has been cultivated, and it must.." The old man carefully taught his own cultivation experience.

It wasn't until the evening that Xi Xiao returned to the courtyard and continued to practice the method of holding his breath and washing his pulse according to the teacher's guidance.

Another decade has passed.

On this day, someone from the Imperial History Mansion reported that the Dragon King would summon him tomorrow.

On the second day, when he came to the Cezhi Palace, Xi Xiaojin stepped into the square of the palace, and felt that the atmosphere was very depressing, and the thirty or so people standing in the field were all frowning and whispering.

After a cup of tea, the dragon king walked out from behind the high platform dragon chair, followed by a group of princes, all with sad faces.

When everyone stood still, Nishizawa, who was standing next to the Dragon King, cleared his throat.

"Ladies and gentlemen, the Dragon King has convened urgently to discuss important matters. ”

"In the war between the Dragon Palace of the West Sea and the South China Sea, we have lost one after another in recent years, and nearly half of the losses have been fierce, and the border area is in danger. ”

"How can this be? Isn't it always evenly matched?"

"I've heard that thirty years ago, the twenty-seven Deep Sea Realm generals who were added to the border as the backbone of the border region have now killed sixteen of them, and more than half of them have already passed!"

The crowd began to talk about it.

"Please be quiet!" Nishizawa was a little dissatisfied.

"The strongest person guarding the border of my Xihai Dragon Palace, the expeditionary general Xi Jinxuan and the Pingnan general Yan Ze, who have entered the adverse sea realm, were shamelessly attacked by the people of the South China Sea Dragon Palace in the ruins of the ancient battlefield a few days ago, and the other party dispatched three strong people in the adverse sea realm to seriously injure General Yan Ze. Nishizawa continued with a solemn expression.

"The Dragon King has an order, form a new army in advance, and gallop to the border!"

"To convene you here is to nominate a candidate for the leadership of the new army. ”

"Although the border area is dangerous, it is also an excellent place to make achievements, who wants to go there?" the dragon king's powerful voice sounded.

This is the second time that Xi Xiao has seen the dragon king from a distance, his body is medium, his face is thin and his forehead is long, his eyes are straight, he is wearing a purple and gold crown, he is wearing a blue interwoven silk embroidered dragon brocade robe, and a dark purple dragon belt is tied around his waist.

After a few breaths of silence in the entire hall, Nishitaki in gray armor fell out of the ranks, "Erchen is willing to go!"

"Weichen is also willing to go!" The dragon king lined up on the left, and the fourth person in the order, the young man in black armor also paced out of the queue.

Wechen is also willing to go. The crowd scrambled to speak.

"Very good!" the dragon king's face finally softened slightly.

But there are also a small number of people who hesitate and do not say anything.

Xi Xiao was a little dazed, focusing on his cultivation, he knew very little about the world, and he was digesting the information such as "border regions and ancient battlefields" in everyone's mouths.

"Erchen recommends one!" Nishizawa's deep and gloomy voice sounded.

"Who?" the Dragon King took Nishizawa's suggestion seriously.

"This person is Xi Xiao, the commander of the five cars!"

"Since returning to the Dragon Palace, in just more than 30 years, Xi Xiao has easily won the championship in the competition of the Upper Academy, and now he can enter the deep sea realm, which can be described as the leader of the younger generation of the Wang Academy. ”

"This reinforcement, Erchen thinks, just let Xi Xiao experience a little, maybe it will be of great benefit to his future growth. ”

"Would you like to?" the Dragon King turned his gaze to Xi Xiao.

"Give it your all. Xi Xiao never expected that Xi Ze would recommend himself, and when the Dragon King asked, he came back to his senses and replied.

"The candidates for the generals of the new army and the military positions they hold will be edicted three days later, and within three days of the edict being issued, the generals will go to Enzetai to receive armor and rewards, and gather in front of the south gate of the Dragon Palace a month later. Nishizawa announced.

"Stand down. The Dragon King stood up and said.

Exiting the Cezhi Palace, Xi Xiao came to the teacher and said goodbye to the honorable professor.

The next day, the honorable professor came to the Xixiao courtyard, gave a thousand body protection pills at one time, and instructed the Xixiao battlefield to change rapidly, everything must be considered thoroughly, not to be strong, to save his life, and left.

Three days later, someone from Yushitai came and handed over the edict of the new army to Xi Xiao.

The Dragon King's uncle, Yu Hou Xihao, a double powerhouse against the sea realm, was urgently recalled by the Dragon King as the commander of the new army.

Assassin Hou Xi Hongzhe, Wang Tong made Xi Taki fall into the deep sea seven realms, for the new army deputy commander, the three of them sit in the middle of the army, under the jurisdiction of the left front, right front, center, left reserve, right reserve five armies a total of 100,000 soldiers, each army has a chief general, command the left front, right front, center, left reserve, right reserve five battalions of five deputy generals.

Xi Xiao is the deputy general of the right front battalion of the left front army, commanding the 2,000 rhinoceros heavy armored army.

Song Qiyi defeated the challenger Xi Xiujun in the student competition of the Academy, and successfully entered the Academy of Honorable Scholars with the second place, and broke through to the deep sea realm two years ago, becoming the right former deputy general of the Right Reserve Army, leading the 3,000 eels female army.

During the period before departure, Xi Xiao kept comprehending the thunder cracking technique in the Wuche Pavilion, and during this time, he went to Enzetai and received cold iron armor and a foot of space.

The so-called one-foot space is a space object refined by the head of the Foundry Division, which is a palm-sized dark yellow bag, with an extremely soft texture, and a space of its own, which can place all kinds of items, but cannot place living objects, otherwise it will cause the space to collapse.

On the day of the expedition, Xi Xiao wore armor and a jade plaque of the deputy general, came to the south gate, and stood in the left front military formation.

An hour later, the order sounded, and the whole army marched in unison and headed south.

During the march, from the conversations of the other four lieutenant generals, Xi Xiao learned the beginning and end of the border dispute.

In ancient times, there was originally only one dragon clan in the entire sea area, and the Dragon Emperor gave birth to four sons, all of whom were talented and extraordinary.

For the throne of the dragon king, the four princes turned against each other, causing a sea war, the war lasted for a thousand years, the four princes were killed or plotted to death, and their descendants were unscrupulous in revenge, and began to slaughter each other's women and children.

Seeing that the war in the sea area was out of control, it had reached the point of annihilating nature, so he had to personally take action, cast the Four Elephant Divine Needles from the Heavenly Court, and set it in the middle of the sea area, dividing the entire sea area into four regions, southeast, northwest, and west, and washing the marrow and cutting the veins of all the ethnic groups in the four domains, and the combat power of the cross-domain battle was reduced to a quarter.

At the same time, in order to avoid excessive comfort and abandonment of cultivation after the armistice of each domain, the Heavenly Emperor set up a buffer zone with a radius of thousands of miles between the adjacent sea areas, and the combat power of each domain entering it was not affected, and threw the supreme exercises, rare treasures, and even the rare treasures of the Heavenly Court of the Ancient Dragon Emperor clan into the buffer ground, and each domain fought for it by itself.

The buffer area is called the border area by later generations, and the ruins of the ancient battlefield are one of them, it is said that rare and exotic treasures appear frequently, so the battle outbreak is also the most frequent, but in the border area, the chaos is clustered, and the poisonous things, the ancient flood beasts, the hollows of the ground, the turbulence of the four elephants, etc., appear randomly, and if you are not careful, you will be crushed and destroyed.
