After making a big turn on the surface of the alloy, Ying Zheng returned to the ground.

Hu Yu hurriedly leaned over and asked, "Your Majesty, what's interesting down there?" ”

Ying Zheng shook his head and said, "It's nothing fun, it's just a big hole." ”

Hu Yu looked at the huge gap, pointed his finger, and asked, "Is that the big hole?" ”

"yes, it's the hole." Ying Zheng said, "If there is no black fire oil, the hole will not be able to be made." ”

On the way back, Ying Zheng told Hu Yu about using black fire oil to make a quenching solution.

"Where did all the dissolved alloys go, did they just disappear?" What Hu Yu is concerned about is not how to use black fire oil to refine the quenching solution, nor how to dissolve the alloy in the quenching solution, but where the alloy goes.

People still have to make a lot of magic weapons out of that alloy!

Hearing Hu Yu say this, Ying Zheng thought of this question, so he looked at Li Si and asked, "Yes, sir, what about those dissolved alloys?" Where did it all go? ”

Li Si smiled and said, "Naturally, it is used to forge 'my weapon', but it is not placed here, after all, the alloy here will be dissolved in the future, and if you move it then, it will be very troublesome." ”

"Let's go, let's see." Ying Zheng said.

"Your Majesty, Madame, please." With that, Li Si led the way in front and came to the other side of the secret room.

It used to be a sloping hillside, but now it has been dug into flat ground, just to the side of the barracks.

I saw that the familiar instruments were placed here in a staggered and orderly manner, and the craftsmen of the Jingjia class were sweating in full swing.

Jing Fan shouted, and when the craftsmen saw that King Qin was coming, they put down their work and surrounded them.

An older craftsman held a "I instrument" in both hands and handed it to Ying Zheng.

"Look, your lord, this is a freshly made fellow, and it's still hot." Said the older craftsman.

Ying Zheng took the "my device", weighed it, knocked it with his hand again, and said, "Yes, how much have you made now?" ”

"Back to the king, more than seventy have been made." Jing Fan replied.

"Good!" Ying Zheng smiled and closed his mouth, "This handful, the widow will take it directly, and the rest, when the widow returns to Xianyang, take the remaining twenty or so, if you forge them all within three days, then our bet will win!" ”

"Good!" There was a burst of cheers from the craftsmen.

"Brethren!" Jing Fan said loudly, "Start the set of instruments that we have in reserve, this time, whatever you say, you will give the king a long face!" ”

"Good!" After another cheer from the craftsmen, they all set out to start the spare equipment.

Hu Yu came to Yingzheng's side and said in a low voice: "Your Majesty, when you told your father that a barrel of black fire oil could only make two or three 'I instruments', did you deliberately say that it was less?" ”

Ying Zheng: "......"

Silence is golden.

Hu Yu still looked at Ying Zheng with strange eyes.

Ying Zheng had no choice but to hand the divine weapon in his hand to Hu Yu to divert Hu Yu's attention: "Give it back to you." ”

That night, because Ying Zheng brought back two hundred barrels of black fire oil from Zhao State, this event was naturally to celebrate, and King Qin led everyone to drink again.

The next day, Meng Yi, who was searching for information outside, heard the news of Yingzheng's return and immediately rushed back.

"How's it going, is there any progress on your side?" Ying Zheng asked.

"It's a bit rewarding." Meng Yi said, "The information collected by the sergeants is relatively scattered, and it is still being sorted out, but recently, I met a few strangers who were mining black fire oil privately, and they were more familiar with a few brothers in the touch gold class, and Wei Chen was thinking about whether we should bring them over and help us mine black fire oil." ”

"That's a good proposition." Ying Zheng thought about it for a while, and said, "Let them join your gold touching class, the salary is not paid, within a year, it doesn't matter if you can find minerals or black oil, the key is experience, understand?" ”

After bringing back two hundred barrels of black fire oil from Zhao Guo, Ying Zheng's confidence began to harden, and he was not as urgent as before.

"Wechen understands." Meng Yi bowed his head and said, "Since you are no longer in a hurry, please ask the king to take back the dark iron snail." ”

vertex

Ying Zheng thought about it for a moment and said

"Okay, then take it back, and if it is necessary to use this to find ore, you can ask the widow for it." ”

"Okay." After answering, Meng Yi went out to get the snails.

During these three days, everyone was busy.

Li Si led the sergeants to quench the alloy in the alloy pit, and Jing Fan took the Jing family class to forge "my weapon" with the quenched alloy.

Ying Zheng looked east and west, and took care of Hu Yu, after all, her belly was getting bigger and bigger day by day.

When accompanying Hu Yu, Ying Zheng couldn't help but think of another lady in Xianyang, who was bigger than Hu Yu's belly.

I don't know when Nansu went into labor, and the last time I went back, I forgot to ask Imperial Doctor Song.

Ying Zheng pondered in his heart, and he added a little longing in his heart.

Three days passed, and the craftsmen of the Jingjia class forged thirty more "I vessels".

Ten a day, this output is really not blown, if you make more equipment, presumably in a few years, it will not be too much of a problem to equip the entire Daqin.

It seems that the smelting attainments of the Jing family class are getting more and more sophisticated.

On Li Si's side, it was a depth of a few zhang downward, according to Li Si's previous calculations, if this is really a stock of 3,000 "I device" alloys, it should be close to the bottom by now.

However, another day passed, until the sun set, and in the gap, there were still no normal rocks or earth.

This couldn't help but make Ying Zheng a little anxious, pulled Li Si aside, and asked in a low voice: "Sir, is there a deviation in our estimates, the total amount of this alloy is far more than the number of three thousand 'I devices'?" ”

Li Si was also a little unsure, and after thinking for a while, he said: "The matter has come to this point, and the line must not be changed, Weichen's suggestion is that while refining downward, we will also start quenching on the surface, no matter how thick this alloy is, we will not delay." ”

"It seems that this is the only way to go." Ying Zheng sighed lightly.

"The king doesn't have to worry, I think that in the era of the Yellow Emperor, it must have been extremely difficult to search for materials to make alloys, so in this quantity, it will not be too much." Li Si said calmly, "As long as we have patience, there will always be a day when the clouds will be cleared and the water will come out." ”

Ying Zheng nodded and said, "Okay, it's better for the widow to return to Xianyang tomorrow with the 'my weapon' just made by the craftsmen, and you continue to stay here." ”

"The minister ordered the soldiers to work all night to see if they could reach the underside of the alloy before the king returned." Lees said.

"Then the gentleman will have to bother." Ying Zheng arched his hand and said.

After Li Si returned the salute, he walked out of the big tent.

Ying Zheng calmed down a bit, and then went to the new kiln of Jingjiaban to sort out the divine soldiers who were going to bring back to Xianyang.

Everything was packed up, it was late at night, but Yingzheng was not sleepy, and then picked up the "Classic of Mountains and Seas" that he copied and read it by heart.

Ying Zheng's understanding of the Nine Shadows was very abstract at first, and when he heard it from Li Si, he only felt that it should be the opposite world under his feet, which seemed to be closer to the underworld that ordinary people said.

But after seeing Jairus and Xi, Ying Zheng's cognition was completely subverted, and his yearning and curiosity about Jiuyou also increased day by day.

This "Classic of Mountains and Seas" is the painstaking efforts of previous predecessors, although the rhetoric is not gorgeous, the artistic conception is not elegant, but the various strange beasts recorded in it, flowers and fruits are strange, it is easy for people to substitute into it, imagine the appearance of those strange beasts, the peculiarity of those flowers and fruits.

Before he knew it, the sky was already dark, and Ying Zheng finally felt a little sleepy, closed the scroll, and prepared to rest for a while.

But at this moment, I only heard some commotion outside, as if cheering something.

Ying Zheng rubbed his eyes, got up and walked out of the tent.

The sound came from the direction of the alloy gap, and Ying Zheng suddenly lost his sleepiness, quickened his pace, and ran lightly.

As soon as he ran to the gap, he saw that Li Si was sitting on a wooden frame and rising out of the hole, and was pulled to the surface of the alloy by two sergeants.

Ying Zheng also stepped forward to take a hand, and after Li Si stood still, he helped shake off the dust.

"How's it going, sir?" Ying Zheng asked a little eagerly.

Li Si smiled comfortably and said, "Your Majesty, Weichen's body is covered with dust, of course it has been opened. ”

"Really?" Ying Zheng was surprised and delighted, and his eyebrows danced happily, "Take the widow to have a look." ”

"We'll have to wait a little longer." Li Si said, "It's only a small piece of land now, but Wechen has already ordered someone to dig up some of the dirt, and it will come up soon." ”

As he was talking, he saw the wooden frame behind him slowly rise out of the ground, and there was indeed a bucket of dirt inside.

A sergeant lifted the barrel up, put it on the ground, and opened the lid, only to see that the dirt contained in it was dark and shiny, as if it had been coated with black oil.

"This shouldn't be any ordinary soil." Li Si grabbed a handful, then rubbed it with his fingers, "It's probably used to nourish the alloy." ”

"It's to prevent the alloy from being corroded by other things, right?" Ying Zheng asked.

"It could be so." Li Si said with some confusion, "But it's strange to say, if that's the case, why isn't the surrounding area of this large piece of alloy nourished with such soil?" ”

"That's right." Ying Zheng thought for a while, and then asked, "Sir, do you think it's possible, this soil is just a mezzanine, and there is a large piece of alloy hidden underneath?" ”

Li Si thought for a moment and said: "This possibility is not very likely, if there is still a piece of alloy, then it is better to put it tightly together from top to bottom, and there will be no soft soil in the middle." ”

"Whether there is it or not, then dig down, anyway, the tomb of the king will also dig down the passage." Ying Zheng said.

"Yes, Your Majesty." Li Si arched his hand and said, "When all the alloy at the bottom is quenched, let's continue to dig down." Your Majesty, wait a moment, and Wechen will go down and have a look. ”

"Okay." Ying Zheng nodded and said, "You must be careful. ”

Li Si answered, and then led two more people to re-enter the gap in the alloy.

Half an hour passed, and seeing that it was almost time to leave for the cave, Yingzheng could no longer hold back the urgency in his heart, sat on the wooden frame, and ordered the soldiers to put him down.

The wooden frame carrying Ying Zheng slowly descended down.

At an unknown distance below, several torches could be seen fixed to the wall of the well, and several people were also working.

The walls of the wells around are not very smooth, and it seems that in the process of quenching, they have been deliberately left with holes one by one, I don't know if it is for inserting torches or for easy climbing.

Finally reaching the bottom, Ying Zheng jumped off the wooden frame.

I saw that Li Si was refining the last small piece of alloy, and beside him, two sergeants were digging downward, already digging a little more than one person high.

"How's it going, sir?" Ying Zheng asked.

When Ying Zheng first entered this well cave, Li Si knew who came down, and he didn't look back, and said, "It's almost ready, king." ”

Ying Zheng knew that refining this alloy required such meticulous operation, so he stopped bothering and turned his head to look at the two sergeants who were digging in the dirt.

And at this moment, only a "click" was heard, and the sergeant's shovel that was digging seemed to have touched something hard.

Ying Zheng's heart chuckled, and he suddenly became nervous.

I won't let myself be right, is this soil really a mezzanine?

Li Si also heard the noise, but still didn't look back, and said in a low voice: "Don't worry, dig out all the dirt and see what's inside."

The two sergeants answered and began digging in the dirt in all directions.

Ying Zheng swallowed his saliva and stared down nervously.

In a short time, almost all of the dirt below was dug up to the top, and several sergeants next to him carried it to the top.

The hard object that had been touched finally appeared, but it didn't seem to be a large piece of alloy, but more like a box about the size of a book made of alloy.

The sergeant gently wiped the dirt from the alloy box and lifted it out.

At this time, Li Si finally completed the last step, sorted out the alloy solution, and handed it to the sergeant next to him.

"What is this, sir?" Ying Zheng asked.

"It seems to be a box made of alloy." Li Si looked at the object in front of him and said.

"It's actually buried here, is it ......" Ying Zheng has been thinking about who would hide this box in such a difficult place to find.

Li Si and Ying Zheng glanced at each other, and they both had a name in their hearts.

- The Yellow Emperor.

It could only be the Yellow Emperor.
