Zhang Haining's death did not make Li Xian too much immersed in grief, and soon he picked up the mood to attract the generals, now the situation has no time to delay.

Under the narration of Kong Ming and others, Li Xian quickly understood the current situation.

Under the exploration of the royal guards, it has been found out that the place where Wan Jianzong set up the seal is a place called cangqiongjian in the realm of fantasy, which is also the place where most monsters gather.

In other places of the canghuan realm, there are also several space channels for demons. Although we still don't understand the principle of these demons coming here, we can be sure that they can only appear everywhere in the canghuan realm. Undoubtedly, this is a relatively good information.

After a little meditation, Li Xian began to give orders.

"Zhanzhao, when you return to Chang'an, you will bring Ou Yezi immediately. Kongming, you and Gong Jin will lead the army to support Bianliang city first."

"I'll obey you."

After hearing this, Xue Jinlian looked like she wanted to say something. Li Xian naturally understood what she meant. He nodded and said, "you should follow the Qilin army. Pay attention to your safety.".

Hearing the words, Xue Jinlian hurriedly said, "thank you, sir."

Then Li Xian took out several letters and handed them to Bai Yutang. He said, "you should send these letters in person. You must complete them in the above chronological order."

Bai Yutang took the letter and said, "yes, your majesty."

When everything was arranged properly, Li Xian had his own worries. He left behind some troops to clean up the battlefield, and the rest of them left quickly.

Called the two young soldiers that Zhang Haining protected that day, Li Xian pondered for a long time and said, "you two should send Zhang Tianshi's coffin back to Chang'an."

"It's your majesty."

Obviously, the two men are still immersed in grief. Li Xian doesn't deliberately think about Zhang Haining's entrustment. He is very clear that there are some things that others say are not as same as himself. Whether these two teenagers can pass the demons in the future depends on their own. However, if they want to have this day, they should first live and escort the coffin is another thing Another way to let them leave the battlefield, at least, should not let the two lives saved by Zhang Haining die here.

However, other people, they should die.

Li Xian doesn't know. What he knows is that many people will die in this war. However, if we let it go, more people will die. Li Xian doesn't know whether his choice is right or wrong. Maybe this is the emperor's loneliness and helplessness.

Three days later, the dusty Zhan Zhao and Ou Yezi rushed back to the ruins of the holy city. Under the command of Li Xian, the original dilapidated holy city had been cleaned up. This was a front-line base for the expansion of the Tang Dynasty. Even after suffering huge losses, it still needed to be rebuilt.

However, different from before, there is a cemetery outside the city to bury the dead soldiers.

"Your Majesty, Mr. Ou Yezi is here."

"I see. Go down."

After Li Xianduan sat in the middle of the Chinese Army's tent, there stood Ou Yezi, who looked lonely and proud. For a moment, they were speechless and silent to each other.

After a long time, Li Xian broke the silence and said, "you should know what I called you for?"

Ou Yezi nodded and said, "yes, you are for it."

With that, Ou Yezi directly took out the Tianyuan stone that Li Xian had seen once and put it on the table. He didn't have any hesitation, which was very different from what Li Xian thought.

In Li Xian's opinion, ouyezi should know what wanjianzong needs from Tianyuan stone, but he didn't say it all the time. There must be some important reason why he took it away by himself. Before, he had tried several ways to get Tianyuan stone from ouyezi, but who was like this family to take it out directly.

This surprised Li Xian.

As if aware of Li Xian's incomprehension, Ou Yezi casually sat down and said, "in fact, it's useless for me to take this thing. After all, this thing is made by me, but it's just a replica."

Hearing this, Li Xian was stunned. Although he didn't get along with Ou Yezi for a long time and didn't know much about it, he knew very well that such a master of sword casting as Ou Yezi would never imitate.

Ou Yezi seems to be in the memory, frowning and saying: "I have traveled a lot of places, not only in East China, but also about the existence of demons and beasts. The truth about the so-called Millennium catastrophe is that there is something wrong with the seal. Although the person who designed the seal is very skillful, it is not a simple thing to seal the space, no matter how subtle the seal is It also takes time to regain strength, so every millennium, the seal will become very weak. "

Hearing this, Li xianmeng thought of something and said in dismay: "so, this seal can be destroyed. Maybe one day, his strength will be exhausted?"

"You're smart." Ou Yezi nodded and said: "this possibility has always existed, and with the passage of time, the situation has become more and more serious. It's just that the existence of the seal design is beyond our understanding. In other words, they only exist in the legendary world. Therefore, many people have been trying to repair, strengthen and change these seals for many years, Although some progress has been made, the effect is not obvious. Until many years ago, someone found a kind of material that we can't understand in an abandoned seal. "Li XianMei frowned and thought of something. He blurted out: "Tianyuan stone?"

"Not bad." Ou Yezi said: "it's something we can't understand. It can combine the power of various attributes. I searched a lot of ancient books, studied for a long time and made imitations."

"There's something wrong with this replica."

"Yes, although Tianyuan stone can play the role of integrating attributes, the problem is that its purity is not enough. If you want to bear such a strong seal force, you must refine it. However, this kind of Tianyuan stone, which can integrate all attributes, is extremely fragile and not afraid of any attributes. It is very difficult to refine it. Finally, someone put forward an idea, which may be able to pass The power generated after sacrifice does not belong to any attribute. "

"How many lives does it take to refine a qualified Tianyuan stone?"

"I don't know. Someone has done several experiments. Judging from the results, it's hundreds of thousands of creatures. Maybe, before I took back this Tianyuan stone, wanjianzong had been sacrificing and refining for many years. Maybe, it doesn't use many people now."

Ou Yezi sighed, and his expression was very helpless.

Li Xian's heart sank when he heard about hundreds of thousands of people. He finally understood why Ou Yezi never mentioned it. ..
