Although King Zhao agreed to Ying Zheng's proposal, the amount of black fire oil provided by Zhao has not yet been determined.
"I wonder how much black fire oil my father-in-law can provide?" Ying Zheng looked at King Zhao and asked.
King Zhao thought for a while, then looked at Guo Kai, as if asking for Guo Kai's opinion.
Guo Kai cupped his hands and said, "I would like to inform my king that there are only two hundred barrels in the national treasury."
King Zhao nodded and seemed to understand: "Since there are only so many, let's give them all to King Qin. Don't look like we are petty."
"I obey the king's orders." Guo Kai cupped his hands and said.
King Zhao turned his head again and looked at Ying Zheng and said: "Xianxiang, look, I have given you the only inventory. Don't be too short."
Ying Zheng said with a smile: "My father-in-law can donate generously, which is a kindness to Ying Zheng. How can my son-in-law find it too little?"
"In that case, what else do you need?" King Zhao asked.
"My son-in-law came here just for this little difficulty and nothing else." Ying Zheng replied.
"Okay, okay." King Zhao said with a smile, "Now that everything that needs to be discussed has been discussed, let's sign the covenant."
"Okay." Ying Zheng nodded and said.
Immediately, Wen Shi wrote and established an alliance between the two countries as agreed. The two monarchs took out their own seals, stamped them, and then pressed their fingerprints.
Made in duplicate, effective immediately.
King Zhao looked at the seal in Ying Zheng's hand and felt slightly surprised, but it was hard to ask more questions.
After signing the covenant, King Zhao waved his hand and said: "Immediately load the two hundred barrels of black kerosene into the car. When ready, set off with King Qin to Da Qin."
"I obey the king's orders." All the ministers responded in unison.
After another day of repair and preparation, Ying Zheng took Hu Yu, said goodbye to King Zhao, and set off on his way home.
After sending Ying Zheng away, King Zhao gathered all the ministers together again to discuss what they were discussing.
The team led by Ying Zheng walked for three days and finally arrived at the border of Zhao.
While driving in the car, Hu Yu kept looking back reluctantly, as if he couldn't leave his hometown.
"What? Can't bear to leave?" Ying Zheng asked with a smile.
Hu Yu turned his head and seemed to be in a low mood: "Well... a little bit."
There are many things that make Hu Yu unique, and frankness is one of them, which is why Ying Zheng prefers her.
"Both places are homes. If you miss Zhao Guo, I will come back with you more often." Ying Zheng said.
"Okay." Hu Yu smiled knowingly.
"By the way, how much is the reserve of black fire oil in Zhao State?" Ying Zheng didn't ask this question until he walked out of the border of Zhao State.
Hu Yu shook his head and said, "I'm not sure. Probably, it's not just these two hundred barrels. My father said before that this stuff can be used to make lamp oil, and he also encouraged mining."
"I also think that Zhao State's storage should be more than this." Ying Zheng said with a hint of regret, "Then do you know why your father concealed the quantity and didn't give us more?"
Hu Yu shook his head again: "I don't know, and I never ask about my father's affairs."
Ying Zheng touched his chin and said: "In the past few days, I have been thinking about the mystery. According to me, first of all, your father does not want me to create too many magic weapons, because he does not want to be invisible. There is an unstoppable opponent among them. Secondly, King Zhao also planned to exchange for some of his 'weapons' and learn to forge them himself, so that he could strike first."
Hu Yu opened his eyes wide and said, "Didn't you say, Your Majesty, that no one can make this 'my weapon' except Da Qin?"
Ying Zheng nodded and said, "So, your father may have made a miscalculation."
Hu Yu blinked and said, "The two hundred 'my weapons' promised by the king will be fulfilled, right?"
"I Have a Picture Book of Ghosts and Gods"
Ying Zheng sincerely
Said: "This is natural, I will not lose credibility because of these things. As for how King Zhao will use it in the future, that is not within the scope of the covenant."
Ying Zheng's meaning is obvious. If he doesn't learn reasonable moves and formations, even the magic weapon will be difficult to play a greater role.
"Then the king said that if we form an alliance with the Zhao State, even if we meet in war, we will not use our weapon. Is it true?" Hu Yu asked.
"Of course it's true." Ying Zheng grinned and said, "This is an alliance between the two countries, how can it be a child's play?"
"That's good." Hu Yu seemed to finally put his heart into his heart.
And Ying Zheng also let out a sigh in his heart.
Signing a contract means creating more time for yourself.
When they arrived at the Qin Kingdom, the team did not advance towards Xianyang, but went straight to Lishan Mountain.
Because Hu Yu's health had to be taken into consideration, the team did not move very fast. At this time, Ying Zheng was not in a hurry anymore, but was a little concerned about the progress of Lishan's project.
On this day, we finally arrived at the foot of Lishan Mountain, and saw the checkpoint to seal the mountain from a distance, with a group of soldiers patrolling.
Ying Zheng came closer to Hu Yu and said, "Don't you always want to come to Lishan to see it? Now your wish has come true."
Hu Yu said happily: "I know that I will definitely come here before my sisters, and I have to choose a good place in the royal tomb first."
Ying Zheng: "..."
Is this even better?
What is your logic?
While they were joking, Meng Tian came out with his team.
"We sincerely welcome the king to return to Qin." Meng Tian dismounted his horse and bowed.
The soldiers who came out to greet him all knelt down and worshiped.
Ying Zheng got out of the car and was extremely happy to see Da Qin's soldiers. He walked forward quickly and said: "Quickly excuse me."
Ying Zheng stepped forward and helped Meng Tian up. The two grabbed each other's wrists and smiled at each other.
"Your Majesty, how was your trip? Did it go well?" Meng Tian asked with concern.
Ying Zheng smiled and said, "Of course it goes well. When a son-in-law meets his father-in-law, how can it not go well? Look,"
After saying that, Ying Zheng pointed to the convoy behind.
Meng Tian looked along Ying Zheng's hand and saw that the long convoy behind was loaded with large wooden barrels.
"Is that... black fire oil?" Meng Tian asked in shock.
"Not bad." Ying Zheng said proudly, "Two hundred barrels in total."
"Hahaha..." Meng Tian almost jumped up with joy, "Now the problem is solved."
"Well, let's go and talk about it when we get back." Ying Zheng said.
"Okay." Meng Tian helped Ying Zheng into the car and escorted Ying Zheng and Hu Yu to the Chinese military tent next to the secret room.
Li Si and Jing Fan received the notice and were already waiting outside the tent.
After bowing to Ying Zheng and Hu Yu, everyone gathered around King Qin and his wife and walked into the big tent.
After sitting down, Ying Zheng looked at the curious eyes of everyone and recounted his experience of going to Zhao State in detail.
After listening to Ying Zheng's description, Li Si smiled and said, "In this way, we have successfully exchanged the black fire oil."
"Yes, the king has also made an alliance with the State of Zhao. It seems that in a short time, the border between Qin and Zhao will be peaceful." Meng Tian followed up.
"It's just a pity for those two hundred magic weapons." Jing Fan sighed.
Hu Yu curled his lips and glanced at Jing Fan.
Li Si quickly smoothed things over and said: "It's not a pity, it's not a pity, that is the reward that Zhao deserves. Without those black fire oils, we would not be able to build this magic weapon, and the construction of the royal tomb will be delayed."
"Sir, what you said makes sense. Zhao Guo's help to us this time is indeed not small." Ying Zheng said, "When we are done, I will thank them very much."
Only then did Hu Yu smile again.
Ying Zheng looked at Li Si and said:
"How's the situation here?"
Li Si said: "The changes are not small. Your Majesty, you'd better see it for yourself. I can't explain it clearly in a sentence or two."
"Let's go." Ying Zheng stood up, looking quite eager.
Everyone followed Ying Zheng to the well.
This is not a well, but rather a valley.
It turned out that Li Si had ordered people to dig up all the ground above the alloy and built a corner staircase next to it.
Looking around, the entire surface of the alloy has been exposed, and there are many sergeants working on it. There is a huge gap in the middle of the alloy, which must have been tempered by Li Si using the black fire oil before. part of it.
Judging by time, it only took twenty days for Ying Zheng to leave. The progress of this project was probably too fast.
Before Ying Zheng could recover, he heard Li Si say: "The preliminary steps of tempering the alloy have been completed. Your Majesty, let's go down and take a look."
Ying Zheng nodded and followed Li Si down the side escalator.
Hu Yu also wanted to follow, but was stopped by Ying Zheng.
Hu Yu knew that his body was special now, so he didn't insist anymore.
When he came to the surface of the alloy, Ying Zheng squatted down, took a closer look, and hit the surface of the alloy a few times with his fist.
It's really hard.
Several people came to the side of the giant gap and saw that there should be equipment for making quenching solution on both sides, but the equipment for making "my equipment" didn't seem to be here.
Ying Zheng approached the gap and looked down, only to see a wooden barrel being pulled up by a wheel axle.
"Haha, not bad." Ying Zheng said happily, "It seems that this tempering operation is quite effective."
"Yes, everything is under control." Li Si said, "With more black fire oil, it will only be a matter of time before all the alloys are tempered."
"Sir, how long do you estimate it will take to temper this entire piece of alloy?" Ying Zheng asked with concern.
Li Si thought for a while and said, "It should be completed before winter."
Chief Ying Zheng breathed a sigh of relief and said: "This is the best. If winter enters, construction will probably be impossible. We must solve this problem as soon as possible so that we can fully start construction next year."
"I obey the king's order." Li Si, Jing Fan and others said in unison.
"By the way, do you know the thickness of this alloy now? If we misestimate the quantity, it will be troublesome." Ying Zheng said thoughtfully.
"Your Majesty, the reason why we have been tempering downwards now is because we want to know the exact thickness." Li Si cupped his hands and said, "Then we can calculate the overall quantity."
Ying Zheng pulled Li Si aside and whispered: "Based on the amount that three thousand 'my tools' can smelt, how long will it take to get to the bottom of this alloy?"
Li Si also whispered: "Weichen has already calculated it. If we calculate at the current speed, it will probably take five or six days."
"Can you speed it up?" Ying Zheng asked.
"With the black fire oil that the king brought back, of course there will be no problem." Li Si said, "But it will take three days at the earliest."
"Okay, three days is all." Ying Zheng said, "After I find out the details of this alloy, I will send Hu Yu back. Otherwise, if I return to Xianyang now, I will not be at ease after all."
"What about Madam...?" Li Si was worried that Hu Yu's already tired body would be unable to bear the burden of living in such a difficult place.
"It's okay." Ying Zheng waved his hand gently and said, "She wishes she could play here for a few more days. Maybe she won't want to leave after three days."
The two of them looked at Hu Yu on the ground in unison, and couldn't help but smile at each other.
Hu Yu had been staring at the surface of the alloy in a daze, not paying attention to the movements on Ying Zheng's side, but suddenly his ears felt warm.
