Liu Cheng didn't know that Xun Yu had refined or fused one of Wang Fugui's martial soul fragments to Cao An, but Cao Mansion was under Liu Cheng's strict monitoring from the beginning, so it was impossible to hide the changes in Cao Mansion that day.

This change in Cao Mansion aroused Liu Cheng's high suspicion, so almost the next day after Cao An refined Wang Fugui or fused Wang Fugui's martial spirit, Liu Cheng's envoy arrived again.

The purpose of Liu Cheng's sending people this time is that the fool also knows that he must have come to test the reason for the change in Cao Mansion.

In terms of the general situation of being a thief, for the arrival of Liu Cheng's envoy, it should be prepared to fool around.

However, this time there were no foolish thoughts and actions on the side of Cao Fu, as soon as Liu Cheng's people came over, Cao An, who had just recovered, met in person.

Cao An not only met in person, but even said directly that what Liu Cheng wanted was indeed on him.

And said that although it was not his wish to violate Chengruo, this happened after all, and it was on his side, he asked Liu Cheng to give him ten days, and he would give Liu Cheng an explanation that could satisfy Liu Cheng.

This news quickly spread to Liu Cheng, and surprisingly, Liu Cheng, who heard the news, did not seem to be too excited and angry.

He just ordered the army in Xuzhou to stay still, and waited for Cao An for ten days.

Of course, if Cao An's explanation to him after ten days does not satisfy him, then it is unknown what Liu Cheng will do.

Ten days later, Cao An's confession came.

Or to put it more directly, Cao An came, and he came directly to Qinghai City to meet Liu Cheng.

On this side, Cao An came alone, but he didn't come empty-handed.

When he came, he looked a little embarrassed, with many large and small wounds all over his body, obviously having just experienced a big battle.

And soon, Liu Chengcheng knew who Cao An's big battle was fighting against.

Because the first time he saw Liu Cheng, he directly took out something to Liu Cheng, which was a fist-sized spare.

Although this spar Liu Cheng saw it for the first time, he clearly knew that this spar was a fragment of Wang Fugui's martial soul.

"You stripped him off?" Liu Cheng looked at Cao An, his face was somewhat surprised, and his eyes softened.

He could see that Cao An had a martial soul on his body at this time, but it was not Wang Fugui's martial soul, and the fist-sized martial soul in front of him obviously had a little Cao An's breath.

It is not difficult to analyze from these points alone, the martial soul of Wang Fugui in front of him should have been stripped from himself after Cao An got a substitute.

"I've thought about it, since it's destined to borrow a person's strength, and since my strength borrowing is destined to damage a person's martial soul, then I can only choose Cao Mengde's."

"That is to say, you used the time of these ten days to snatch Cao Mengde's martial soul and replace this fragment with his martial soul?"

Liu Cheng pinched Wang Fugui's martial soul and asked, there was not much superfluous expression on his face, and it was difficult to see what he really thought now: "Why?" ”

"Da Zhu Guo is a loyal minister of my Great Zhou, and he is a modified model for my subjects of Great Zhou, since he has hope of resurrection, it is too late for me to help as the prime minister of Great Zhou, how can I stop and hinder this matter."

If Cao An hadn't said this in front of Liu Cheng, Liu Cheng would never have believed it.

But now that Liu Cheng is looking at Wang Fugui, it is really difficult for him to doubt Cao An's words.

At this time, Cao An was very different from when he returned the martial soul to Guo Jia and the others, and his temperament and mentality seemed to be sublimated.

Of course, Liu Cheng's focus at this time was not on Cao An's state.

He didn't even care whether Cao An's words were true or false, as long as Wang Fugui's martial soul returned to his hands, all this would be fine.

I have to say that although he didn't expect anything from Cao An to explain to him at the beginning, Cao An really gave him a big surprise this time.

However, what Liu Cheng didn't expect was that Cao An was going to surprise him more than that.

"King Kang, the martial soul fragment of the Great Pillar Kingdom, if there is any news that can inform me, I will help King Kang collect it." Cao An then said.

For this, Liu Cheng just nodded and thanked him.

"By the way, there is one more thing, King Kang's soldiers and horses in Xuzhou should be recovered, right?"

"Take it back? What do you do with it? I'm also going to take Xuzhou down. Liu Cheng raised his eyebrows.

"Xuzhou is not so simple, King Kang may be able to take down most of Xuzhou, but it is not so easy to take Xuzhou, and King Kang's recent actions have caused a lot of dissatisfaction from the forces that do not want to have any chaos in the recent period, if you continue, it is not good to say that you will face the encirclement and suppression of several forces." Cao An responded.

Most of what Cao An said Liu Cheng knew, but the focus of Liu Cheng's attention at this time was that Cao An's words seemed to contain some information that Liu Cheng did not know.

"It's been more than a year since my father-in-law fell, and it's been more than a year since these forces that popped up overnight have been peaceful.

Cao An nodded: "I just fused all of Cao Mengde's martial souls to find out about this." ”

"In the past year, the reason why they have been safe and sound is because they are all planning and preparing to forge national weapons."

"National weapon?" Liu Cheng was stunned for a moment, and subconsciously thought of the Chixiao Sword he encountered before, but looking back, that Chixiao Sword didn't seem to be very strong, and those martial soul forces shouldn't have been forging such a weapon for so long.

According to Cao Mengde's memory, as long as the national weapon is built, it can enhance the luck and strength of the entire force.

Of course, this is not the final focus, the most important thing is that only when they have created a national weapon can they really start competing for the world? ”

"Why?" Liu Cheng's eyes lit up, he never thought that the secret he had been digging for so long would be opened in front of him in this way.

"I don't know what the specific reason is, but what I can be sure of is that this is the deepest secret in Cao Mengde's memory, and it should be a secret that belongs to the leader of the martial soul force alone.

But it's not difficult to figure out this matter, we can also forge a national weapon! ”
