Guo An didn't know it, because of the unintentional entry of his catfish, the group of officials in the Yanwang Palace, who had already prepared to mess around, also felt some crises and began to move.

I still get up on time every day, eat, order, and go to the morning hall.

Then, wait until Zhu Liang arrives with a carriage, and then go to Shangzhuang Village Iron Metallurgy.

After checking the solidity of the cement walls that had been built up in the previous two days, I improved the recipe, stirred it again, set it aside to dry, and then recorded it, and then took the carriage back to the county office.

In this way, after testing more than a dozen times, looking at the cement wall in front of him that was already dry and hard and couldn't be kicked in, Guo An's face finally showed a smile.

"Guo Xianzun, but it's done?"

Behind him, Zhu Liang, who had been paying attention to Guo An's expression, hurriedly asked.

"Exactly!"

Guo An nodded slightly.

A trace of doubt flashed in Zhu Liang's eyes, "Guo Xianzun is going to use this cement to build a three-zhang high house?" ”

Guo An smiled lightly, "If General Zhu has any doubts in his heart, just give it a try." ”

Zhu Liang had wanted to try it for a long time, and suddenly asked: "Dare to ask Guo Xianzun, how will he try it in the end?" ”

"Push, kick, even with a sledgehammer, it's up to you!" Guo An said.

Zhu Liang grinned, "Guo Xianzun, don't worry, the one-foot-thick stone wall can be pushed down by the last general." ”

"Hmm!"

Guo An responded casually, then found a shady place, sat down directly, and prepared to watch the play.

Zhong Huo and the craftsmen all gathered around with curiosity on their faces.

"Guo Xianzun, did the last general really do it?"

"Don't ink, after you're done, don't you have to hurry up and go back to report the good news to His Royal Highness King Yan?"

Guo An urged impatiently.

Zhu Liang was stunned, he almost forgot about the big thing.

Immediately, he bowed down slightly and pushed hard against the half-human-high stone wall in front of him.

"Huh?"

Motionless!

Zhu Liang's face flushed slightly, ready to come down, and exerted himself again.

"Hmm~ha......"

The stone walls shook slightly.

"How is this possible?"

A trace of shock flashed in Zhu Liang's eyes, and the small vision in his heart was completely put away.

After taking a few steps back, he ran towards the stone wall, and finally kicked hard.

The stone wall still shook slightly, and did not fall.

Guo An smiled and said, "I'm tired of the blacksmith head, go and get a sledgehammer for General Zhu." ”

"Yes, Xianzun."

The blacksmith and the others had already seen it with excitement, and they didn't know how strong the cement was after solidification, so they didn't dare to knock it hard and touch it without permission.

Now, they know that the cement they have calcined these days is so strong?

"County Zun, the last general will not use a hammer, as long as he kicks a few more times, he will definitely be able to kick this stone wall down!"

As for Zhu Liang, although he was sweating profusely, he still refused with a face full of refusal.

Guo An asked speechlessly: "Kicked down, then how can you test the solidity of the stone wall?" ”

"This ......"

Zhu Liang was stunned.

"Zhu Baihu, the sledgehammer is here!"

At this time, the blacksmith head had already come over with a sledgehammer.

Seeing this, Zhu Liang didn't insist anymore.

Although he is reckless, he is not stupid.

If you can hit it with a hammer, why do you have to kick it with your own feet?

Hiss......

Taking the sledgehammer, Zhu Liang subconsciously grinned, the cement and stone wall in front of him was so strong, and his feet still hurt after the shock.

"Boom!"

As the sledgehammer slammed into the stone wall, several cracks were evident in the stone wall, but they did not break.

"So sturdy?"

"Even if it's a real monolith, that's it, right?"

Around, Zhong Huo and a group of craftsmen all subconsciously opened their mouths wide, their faces full of shock.

Looking at the traces on the stone wall in front of him, Zhu Liang's pupils also shrank, and only he knew best how strong his strength was.

A hammer down, but it hasn't been completely smashed?

"Knock ......"

Thinking about it, Zhu Liang couldn't help it, and hammered it down again.

Crash......

This time, the stone wall finally shattered!

Looking at the shattered cement stone wall, Guo An couldn't help but widen his eyes, he seemed to have missed King Yan.

"Guo Xianzun, the last general is fortunate not to be dishonored, and finally smashed the stone wall!"

Zhu Liang looked at Guo An under the eaves with a smile on his face, his face couldn't help but stiffen, but he found that the expression on Guo An's face was a little wrong.

"Zhu Baihu, this official just wants you to test the strength of the stone wall. Now, you smashed the stone wall, if King Yan comes tomorrow, what will you show King Yan to see? ”

"Huh!"

Zhu Liang couldn't help but smile.

Guo An sighed helplessly, and looked at the blacksmith head and others on the side, "There are still a few people to worry about building the cement wall again."

This time, you should stir some small gravel into it, and if you can, you can also insert some iron bars into it, and when it is dry, even if General Zhu smashes it with a hammer again, it will not be smashed so easily! ”

"Guo Xianzun rest assured, the villain and others will definitely build the wall tomorrow, and His Royal Highness will not crack it!"

Zhong Huo and the blacksmith head assured solemnly.

Guo An's face was stunned, "You can do your best......"

……

"Your Highness, Your Highness!"

After sending Guo An back to the county office, Zhu Liang hurriedly ran back to the Yanwang Palace.

"What makes you so flustered?"

Zhu Di asked with some curiosity.

"Your Highness, God! It's really amazing......"

At this time, Zhu Liang had long lost his composure in the iron smelting station, and reported to Zhu Diyu with excitement on his face.

"The cement developed by Guo Xianzun has succeeded, and the wall built with that cement is a hundred times stronger than glutinous rice mortar, and it is as solid as a boulder.

"Is it really that strong?"

Zhu Di was a little skeptical.

It would be two days before the five days he had said the other day.

"Your Highness, this is what the last general has personally tried, and he will never dare to deceive His Highness." Zhu Liang said with a solemn face.

"Very good."

Zhu Di nodded slightly, "This king will go to Shangzhuang Village Iron Smelting Institute tomorrow to inspect it personally." ”

"Yes, Your Highness......"

Early the next morning.

Guo An had just finished the morning hall when Zhu Di broke in.

"Your Highness."

Zhu Di said directly: "Follow this king to the Shangzhuang Village Iron Works." ”

"Huh?"

Guo An was stunned for a moment, and then said with a somewhat strange face: "Your Highness, but you want to go and check the cement and stone wall?" ”

"Self!"

Guo An smiled bitterly: "I'm afraid I'm going to disappoint Your Highness, the cement and stone wall built yesterday has been smashed by Zhu Baihu."

His Royal Highness went down, and he could only see some broken remnants of the broken wall. ”

"Huh?"

Zhu Di slowly turned his head and looked at Zhu Liang.

Zhu Liang's face was anxious, and he hurriedly said: "Your Highness, don't worry, when I left yesterday, Zhong Huo and those craftsmen had already rebuilt the cement and stone wall, and they would definitely be able to build it today." ”

Hearing this, Zhu Di's expression eased slightly.

Guo An hit mercilessly again, "It's a pity that the cement stone wall needs at least three days to dry thoroughly and become solid." ”

"Three days?"

Zhu Di's eyes widened.

Guo An replied honestly, "Exactly, if Your Highness doesn't believe it, you can ask Zhu Baihu, Xia Guan went a few days ago, and he was testing the cement stone wall built two days ago." ”

Zhu Liang's face stiffened, and he nodded slowly.
