Silence Valkyrie

Chapter 530
Nanhua opened it curiously, his expression changed drastically, and he couldn't help but exclaimed: "The Crystal of the Void! It's still the best!"

She said excitedly, picked up the prismatic crystal and looked at it carefully for a long while before putting it back into the box reluctantly.

Only then did Zhang Shan ask aloud: "What is this crystal of the void used for?"

"The crystal of the void is the most superior power source!" Nanhua replied.

Seeing that Zhang Shan didn't understand clearly, she then explained in detail.

The crystal of the void has a wonderful ability, that is, it can connect to a natural node in the void. Under the control of a proper magic circle, it can continuously extract void energy from the void without worrying about exhaustion.

But this kind of void crystal is not an ore, it is not produced in the vein, it will only be bred in some extreme environments, such as places like the twisted forest, so it is extremely rare and can not be found.

The most important use of void crystals in the sanctuary is that if the volume is large enough, it can be used as a power source for building an interplanetary teleportation array.

And the most used is on the power furnace for building void ships, which are large magic weapons that can travel through the void and travel between various continents and planes.

As long as a finger-sized Void Crystal is enough to refine the power furnace of an ordinary-level Void Ship, and the Void Crystal that Zhang Shan took out is as big as a palm, it can be used as the Void Mothership with the highest level in the Sanctuary power furnace.

So far, the dignified Zhenwu Shengchao mothership-class voidships are very limited, only a dozen or so. The reason why there are so few is that there are not enough large void crystals, so the power furnace cannot be built.

If Zhang Shan dedicates this Void Crystal to the Holy Dynasty, then the Holy Dynasty will be able to build one more mothership-class void ship, and the Holy Dynasty will not be stingy with rewards.

After listening to Nan Hua's introduction, Zhang Shan was delighted but also felt a little difficult.

Void crystals are one of the strategic materials that are forbidden to be traded in the Holy Dynasty. Not everyone can dispose of them, and individuals are not allowed to own them.

Nan Ruoli and Zhang Shan exchanged glances, they naturally understood what each other was thinking, she pondered for a while and said: "We can't keep this thing, I'll find a way to get rid of it."

In the following days, Jiuyuan City was quite peaceful.

After receiving Zhang Jiesi's reward, Zhang Clan didn't react too aggressively, maybe he just tolerated it temporarily, and then deal with them when it's appropriate in the future.

The bloody battle on the holy battlefield is still going on, and from the regular reports sent by the expeditionary army headquarters, it can be known that the battle is becoming more and more fierce and bloody.

However, Jiuyuan City is like a safe haven because it has severely damaged the demon army. For the time being, there is no demon army actively attacking. Could it be that there has been a period of calm, and the city is also full of people and order.

During this period of time, Zhang Shan mostly retreated in the underground secret room of the City Lord's Mansion. Now he has officially advanced to the high-level Yin-Yang Realm, and his strength has greatly increased.

After that, he ignored the mundane affairs and concentrated on his cultivation, intending to polish his realm to perfection in the shortest possible time, and then use the marrow washing pool of the Sun Clan to attack the Guiyuan realm.

Now he can enter five hours a day in his spiritual cave, and the space time difference can reach one to forty, that is to say, one hour of his cultivation in the spiritual realm is equivalent to forty hours in the outside world.

If he uses up five hours of cultivation every day, it is equivalent to two hundred hours of cultivation. Calculated by twelve hours a day, each day of his practice is equivalent to about sixteen and a half days of others' cultivation.

A month's time is equivalent to almost a year and a half of cultivation, so his cultivation progress can be said to be advancing by leaps and bounds, and he has reached the peak of the Yin-Yang realm, and he can consider hitting the Yuanyuan realm.

However, Zhang Shan is still hesitant about going to the Sun Clan's family, and Nan Ruoli is busy doing battle preparation work, so the peace in Jiuyuan City will not last long.

And according to her plan, after preparing for battle, she plans to lead the Jiuyuan Army to sweep the nearby demon-controlled areas, at least level the demon-occupied areas adjacent to the Jiuyuan theater, consolidate and expand her territory, and strengthen the strategy of Jiuyuan City depth.

On this day, it was afternoon.

The sky in Jiuyuan City is still leaden gray as usual.

Zhang Shan walked slowly on the streets of Jiuyuan City, observing the city now under the name of their master and apprentice, feeling a little hesitant in his heart.

A large area destroyed by war is under construction ahead, and various technicians and workers are busy, a scene full of enthusiasm.

Among them, some construction machinery brought by the sanctuary made a huge roar.

Both the repair of the city wall and the reconstruction of the urban area are almost coming to an end. It won't be long before a repaired and more perfect Jiuyuan City will become the most important forward base in this theater.

This is the Holy Demon Battlefield, where destruction and construction, survival and death are two seemingly eternal themes.

Zhang Shan stood on a section of the city wall that had just been repaired, looking at the sky that was about to darken in the distance. The night in Jiuyuan City came earlier, and the wilderness in the distance could no longer be seen clearly.

Suddenly, he realized something, and he turned his head. On a street next to the city wall, a young man was standing in the middle of the street, looking at him with sharp eyes.

The man raised his feet in the air and walked in front of Zhang Shan step by step in the air. His short hair was blown slightly by the wind, his handsome face was bright and his eyes were bright. He smiled at him and said, "Hello, Zhang Shan."

Zhang Shan replied with a self-contained smile: "I don't know how to call Xiongtai?"

"I'm Sun Shihong, from the Sanctuary Sun Clan!" the person introduced himself.

Zhang Shan's pupils shrank. He had heard Nan Ruoli mention this name when he talked about the background of the Sun Clan. He was a well-known direct descendant of the younger generation of the Sun Clan. He was a brother of the Sun Shitao, who was known as the first genius of the young man in the Sanctuary. , ranked second.

"It turned out to be the Second Young Master Sun, what a pleasure to meet you!"

Zhang Shan cupped his hands and said, and then looked at Sun Shihong again.

I saw that he was just wearing an ordinary samurai uniform. Apart from his handsome face and tall figure, he looked no different from an ordinary warrior at first glance.

And Sun Shihong also looked at Zhang Shan carefully, and said with an undiminished smile on his face: "Recently, I often hear your name mentioned. You are talking about killing the demon general Lu Sha in the army. I just want to see you." On the other side, if possible, I would like to fight a battle to see what kind of hero he is."

Zhang Shan shook his head and smiled modestly: "If Second Young Master Sun is interested, I will accompany you, but I'm afraid I won't be able to catch the Second Young Master's eyes."

A gleam of light flashed in Sun Shihong's dark eyes, he was obviously very excited, and he meant to make a move now.

However, he pondered for a while, and said with regret: "I am here this time to take you back to the old mansion in the sanctuary. It is best not to get injured before entering the marrow washing pool, so the competition will wait until you break through the return to the original state." Besides, and under the will of Huo Dou, this is not a suitable place for competition."
