The affairs of the academy were finally completed, and there were no major problems, but the people who did not report their names were a little disappointed.

Fortunately, Xiang Han promised to expand the enrollment next year, and the people left one by one. It's just that they all secretly made up their minds in their hearts that next year, they must come early and queue up a few days in advance!

After this matter was settled, Xiang Han was able to be idle again, as for the glass refining method he had obtained before, he originally wanted to find someone to produce glass, but he never found the right person, and this matter was put on hold!

"Master, someone came to find the lord, and he came in a hurry!" Just when Xiang Han and the girls kissed me and me in the backyard, playing the piano and saying love, someone came to find Xiang Han.

"Who is it?" Xiang Han frowned and asked.

"I don't know, his face is dark, as if he has been burned, and he doesn't report his name, but his mouth is full of looking for the lord." The servant spoke.

"Oh?" Xiang Han was slightly stunned, what kind of shape is this? Stepping into the front hall, I saw a person with a dark face and a lot of burnt hair, the most important thing is this head shape, the whole head exploded!

Who's this? What kind of look is this? It's too chic, right?

"My lord! It's done! It's done! After this person saw Xiang Han, he immediately opened his mouth and said very excitedly.

Hearing this voice, Xiang Han seemed to remember who this was: "Are you ...... Cai Ming? ”

"That's right! It's a subordinate! It's a subordinate! Cai Ming nodded excitedly. Cai Ming said it was done? Combined with Cai Ming's appearance, Xiang Han seemed to realize something in his heart.

It can't be that black powder has been successfully developed, right?

"You're done? What is it? Xiang Han was a little incredulous and asked suspiciously.

"It's gunpowder! The gunpowder that the lord asked his subordinates to study before! Cai Ming said.

"This shape of yours was blown up by gunpowder?" Xiang Han pointed at Cai Ming.

"Uh...... That's right! Cai Ming nodded a little embarrassedly.

"How powerful is this black powder now?" Xiang Han asked. Now it has been several years since he asked Cai Ming to study, and Cai Ming said it, there must be a big breakthrough, right?

"The lord comes down with his subordinates, and the subordinates experiment with the lord!" Cai Ming said.

"Good!" Xiang Han nodded. As Cai Ming came to the suburbs, there was a vacant land here, which Xiang Han specially left for Cai Ming to experiment.

Cai Ming prepared a ten-pound wine jar, which was filled with black powder, and then threw a long lead out, and there was a fence nearby, and there were some pigs, cattle and sheep in the fence!

"Please light the fire." Cai Ming handed the torch to Xiang Han. Xiang Han nodded, and then lit the fuse.

Everyone involuntarily covered their ears and quietly waited for this jar of black powder to explode!

"Boom!" With a loud bang, the ground shook, and the House of Black Powder exploded, forming a pit in the same place.

Even if he was a hundred steps away, Xiang Han still clearly felt a heat wave and a lot of shaking.

As for the pigs, cows and sheep, those who were close were blown away! The farther ones were also splashed out by the fragments of the wine jar, and the aftermath of the explosion was injured!

Xiang Han couldn't help but scratch his tongue, this power is quite good! When I walked in, the two closest sheep were directly blown up, and the flesh and blood were blurred, and the pigs and cows a little farther away were blown away, covered with dirt and fragments of wine jars.

"Not bad, not bad!" Xiang Han nodded with great satisfaction,

"Is this ratio easy to formulate?"

"Well prepared! Such black powder, as long as there are materials, you can have as many as you want! Cai Ming said very excitedly.

"That's good! The task of preparing this black powder is up to you! When the time comes, I'll let you make a dynamite pack! If anyone dares to invade our state again, give them a few explosives packs to try! Xiang Han smiled slightly.

"Yes!" Cai Ming nodded repeatedly.

"Of course, remember that you must block all the news for me, this thing must not fall into the hands of our enemies!" Xiang Han said in a deep voice.

"Yes! Subordinates understand! Cai Ming nodded, he was personally matched and experimented with his own hands, how could he not know the power of this explosive?

If this does fall into the hands of the enemy, it is no joke!

"Okay, I'll send more troops and horses here, but your image, let's quickly clean up!" The more Xiang Han looked at Cai Ming's image, the more he wanted to laugh.

"Hey, yes, yes!" Cai Ming smiled and didn't care. Xiang Han shook his head, turned around and was about to leave.

But then Xiang Han's footsteps were stagnant, since he was already out of the city, why not go to the orchard to see what the orchard has become now.

Soon, Xiang Han came to the orchard, although it is called an orchard, but now there are no ripe fruits, only thousands of vines.

The grape seeds given by the system are really good, after planting, a lot of germination, plus the later cuttings, now there are more than 1,000 vines in the orchard.

Moreover, the grape trellises have been erected. It looks lush, and it's not bad!

However, because autumn is about to begin, and autumn is followed by winter, in order to keep warm, these special people who are responsible for feeding grapes are building ancient greenhouses!

Now there is no plastic, but the kind of waterproof oiled paper is used, and the insulation effect is not bad, enough for these vines to survive the winter!

Originally, there was no need for greenhouses for the vines, but according to the experience of the old farmers, there may be heavy snow this winter, and the vines are afraid of freezing to death, so the greenhouses are built.

If this vine is really frozen to death, Xiang Han will really have no place to cry! Xiang Han shook his head: "In this way, it is better to call it a vineyard directly!" Looking at the appearance of the vines, Xiang Han shook his head again, if you want to bear fruit, it may not be possible next year, I am afraid that if you want to drink wine, you will need to wait until the year after tomorrow!

However, after waiting for so long, do you still care about such a year or two? However, next to this large field of grapevines, Xiang Han saw something not quite harmonious, all the seeds on this piece of land were peppers!

It is planted with the pepper seeds given at the same time as the pepper noodles given by the previous system! Xiang Han originally wanted to take it to a farmer's house to plant, but he didn't expect Xizhong to send someone to plant it here!

In addition, star anise, cinnamon, and other spices are planted in this vicinity. This made Xiang Han cry and laugh, although it was about to be harvested, but this nondescript planting position, Xi Zhong's arrangement was really enough!

Shaking his head, Xiang Han turned around and left the orchard, no, it should be called the Grape and Spice Garden now!
