The Royal Guards are responsible for the security of the palace, or to be precise, the security of the Emperor, while the Royal Guards are responsible for executing the Emperor's orders, such as arresting and killing individuals.

It can be said that if someone rebels or there is an invasion from outside, the last barrier is the Royal Forest Army and the Imperial Guards. Therefore, the people in these two teams must be the emperor's confidants.

The level of the previous Jinyiwei and Yulinjun was average, and many of them were brought in by nobles and nobles, but Nan Yichen didn't want to be a loser, so they were all reorganized.

Dong Lin was a secret guard, so he was naturally good at training people, but Xiao Dao was a pervert, and the people he trained basically developed in the direction of perversion.

Moreover, early summer also provided some modern physical training methods. When combined with ancient methods, it became a brand new training method, which greatly improved the combat level of personnel.

At this time, Dong Lin personally came in with several imperial guards and took away two high officials.

"Does anyone else have this play?" Nan Yichen took a sip of ice tea.

Everyone looked at Ye Ming subconsciously.

Ye Ming glanced at the crowd and raised an evil smile. How could something suddenly appear all at once? You have to take your time. If you have done something wrong, just be nervous.

"Since there is nothing to do, let's retreat from the court." Nan Yichen stood up, took Chu Xia and left directly.

Xia Jinghan didn't care so much and hurriedly followed me. If you stole me, you have to be responsible for my stomach.

Ye Ming also hurriedly followed him. He hadn't even eaten the shortbread, and the ice drink looked delicious. Unfortunately, the emperor was too stingy and didn't even say that he would be rewarded with a glass, so he had to make up for it.

The two of them took a small road and rushed towards Qiankun Palace. Now there are few masters in the palace, and the imperial kitchen is basically used to prepare meals for the servants. The emperor and empress cook all their meals by themselves whenever they have time in early summer, so those ice tea snacks and the like

Yes, it must be in the small kitchen.

The rest of the people were all very preoccupied and were listless when they left the court. They were all thinking about whether they had done anything outrageous and resentful, and whether there was any way to remedy the situation.

It's a long distance from the Jinluan Palace to the Harem, and you basically have to sit in the Imperial Palace.

It is now the end of June, and although it has not yet reached the hottest period, it is almost noon, and the heat in the square outside will still keep coming.

If you arrive in July and August, it will be even hotter as you can imagine.

In the era without air conditioning, ice cubes were the biggest benefit, but ice cubes were an absolute luxury in summer and were stored in ice cellars in winter. As empresses, Chu Xia and Nan Yichen would not be short of ice.

But what about others?

In early summer, I don’t feel sorry for other people, but I feel sorry for the guards on duty. Not only do they have no place to shade from the sun, but they also have to wear heavy armor to go back and forth on duty. Over time, they will suffer from heatstroke.

In fact, she remembered that there were methods of making ice during the Tang and Song dynasties, and there were even foods similar to ice cream, but it seemed that when history took a turn, it was not passed down.

But the founding queen of the Southern Tang Dynasty was a time-traveling senior. She shouldn't know how to make ice, but she didn't seem to be able to make ice. Of course, her guess was that the time-traveling senior was probably a military expert or a soldier.

Saltpeter was used by her to make weapons... But that's not right, there are no thermal weapons here...

Forget it, forget about that, since she is here, let’s solve the ice problem first.

"Xia Xia, what's wrong?" Nan Yichen looked at Chu Xia and frowned at the square, and hurriedly held her hand, "Are you feeling uncomfortable? Are you hot?"

"Is saltpeter in short supply?"

"Saltpeter?" Nan Yichen was stunned, then shook his head, "That thing is not in short supply, you..."

"Have someone bring some over." Chu Xia smiled, "It's too hot, so we have to make everyone feel comfortable."

Nan Yichen's eyes lit up, and then he asked Dongyang to find saltpeter.

When the two returned to Qiankun Palace, they found Xia Jinghan and Ye Ming sitting at the door depressed, seemingly waiting for them.

"What's going on with you two?" Nan Yichen frowned, "I don't need a doorkeeper here."

"Mom, where's the cake?" Ye Ming looked resentful.

"Girl, where's that ice tea?" Xia Jinghan also had a resentful face.

"Make it right away." Chu Xia smiled. In the past, because she had modern cooking skills, she cooked some things that were not available in this era, which was a coincidence and gained everyone's love. But now, she will add divine spring water to her food.

Although they are all diluted, these ingredients are the kind that people who don't know how to cook can make them casually, and everyone will be fond of them.

What's more, if you eat more often, you will obviously feel better.

This is why everyone is more fascinated by her cooking skills.

A lot of scallion pancakes and rose tea were made here. After the two of them had eaten and drank enough, they sent them away. Of course, the two of them packed up the rest and took it away.

However, Lan Yan soon came in to report that Ye Ming had started a fight with Xiao Dao and Dong Lin at the door.

Chu Xia could only sigh helplessly and asked Lan Yan to call a few people in and cook a lot of various foods for them. This way a bloodshed was avoided.

Xiao Hei and Xiao Bai will also appear in front of Chu Xia on time when it is time to eat. Because of the blessing of the divine spring water, these two guys seem to be more spiritual. However, they also know that everyone is afraid of them, so they usually stay at Leng Palace.

Walking around, watching everyone working, even those who want to steal are unable to escape their pursuit, it is more effective than others.

As soon as the situation here stopped, Dongyang sent a lot of saltpeter. The method of making ice with saltpeter is very simple, which is to use the saltpeter to absorb heat to freeze water. Moreover, the saltpeter can be reused, so the cost is not that expensive.

In early summer, someone made some refrigerators. This refrigerator is not a modern refrigerator, but is made of wood. There are holes all around. A basin and saltpeter are placed inside. The water will melt after freezing, and the cool air will be emitted when it melts.

It can relieve the heat.

After the wooden refrigerator came out, Chu Xia first arranged it for the soldiers on duty in the palace.

Not only did the soldiers standing guard have a parasol above their heads, but there was also a wooden refrigerator under each parasol. The air-conditioning was constantly emitting from those gaps, so it would not feel too uncomfortable to stand there.

A wooden refrigerator can be used for about two to three hours, which is just the time for a change of guard.

Moreover, in early summer, people made mung bean soup and ice tea and put them on the wooden refrigerator to quench their thirst at any time while standing guard. Patrollers can also drink it at any guard point.
