"Is this water seawater?" Li Shimin reached out and touched the water in the pool. In his cognition, only the sea is blue.

"Your Majesty, the sea water is also colorless and transparent, but it is boundless and unfathomable, reflecting the blue sky, and we can see the blue ocean." Merton explained.

"This water is the water that attracts the Taiye Pool, but it is just added with bile alum, in order to remove the algae and prevent the water quality from deteriorating, Your Majesty can rest assured, the Taiyi has tested it, and there is no harm to the human body!"

Of course, Merton will not say that in addition to the algae, the biggest effect of adding bile alum is to make the pool appear slightly blue and beautify the water quality.

Li Shimin bowed, naturally someone in the palace would sit on the security check procedure, otherwise there would be no acceptance today.

"This is a children's area, the depth of the water is no more than three feet, so there is no need to worry about the danger of the princes." Merton was half a step behind, pointing to a shallow and clear sub-pool for Li Shimin and Wei Guifei.

The pool is a place, of course, a place for the whole family to rest, more to play with children, if only one adult is allowed to swim here, it is estimated that it will soon become extremely boring.

"This is an adult area, which is divided into a shallow water recreation area and a deep water area, as well as a jumping platform. and the pool track. ”

The distinction between shallow water and deep water made Li Shimin's eyes light up, but he didn't care, what really interested him was the jumping platform and the track.

"Jumping off the platform is fun?" A smile appeared on the corner of Li Shimin's mouth.

"When Wechen was young. My favorite thing in the summer is to jump into the water over and over again, and the idea involves this jump. Merton explained that swimming in a pool is not fun enough, and adding diving can be ten times more fun.

"The concubine is very curious about this pool track when she arrives?" Wei Guifei was curious, there is no such thing as a swimming competition in this era.

"The pool track is about competing to see who can swim fast and make it more fun." Merton explained that a simple bath is probably not very interesting.

"Why is that?" Wei Guifei's pretty face turned and she said curiously.

"We're thinking that swimming is the best way to exercise, because people use a lot of energy in the water, it doesn't hurt the body, and it helps to slim down and beautify the body," Merton explains. ”

You don't see those sports in later generations, which of the other sports are not full of injuries, only swimming, very few have heard of injuries, and they are all in good shape and temperament, which shows the benefits of swimming.

Which of the princes and grandsons is not very expensive, and it must be thankless to build other sports venues, only the swimming pool is the most suitable.

As for the question of drowning, which prince is not full of people behind him, this question does not need to be considered at all.

"Isn't fifty steps too short? I can swim to the end in one breath! Li Shimin shook his head at the swimming lane with only fifty paces and said, but Merton built a swimming pool track that can be divided into five tracks and can accommodate five people to race.

"Your Majesty, fifty steps is not short, if you swim to fifty meters, you can continue to swim upside down, and if you go back and forth a few times, you will definitely be able to open the gap and divide the winner." Merton smiled bitterly, can you compare in a swimming pool to a natural pond?

Li Shimin nodded regretfully, and accepted Merton's compromise suggestion, the place is limited, and it is good to be able to do this step.

"Your Majesty, please try the artificial beach created by Weichen for you!" Merton pointed to the north side of the pool, which is the most sunny and is the best location for a man-made beach.

Looking sideways, the north side of the pool is paved with golden sand, and in the middle of the beach, five large wooden umbrellas are opened, leaving a large shady area, and two beach chairs are placed under each umbrella for people to rest.

The man-made beach was Merton's biggest regret in building a swimming pool in Mofu, and now he has finally made up for it with the power of the royal family.

"Is this river sand?" Li Shimin bowed his head and grabbed a handful of sand, incredulous.

Merton nodded, it is this artificial beach that is the finishing touch of this pool, the sun, the sand, and the sea water form a unique charm.

After all, seeing a few people who have been to the sea, the pool and beach in front of them can completely replace the reverie of the sea, at least Wei Guifei in front of him is already deeply infatuated with it.

"I really don't know how your brain grows, what seems to others to be so difficult is so easy in your hands!" Li Shimin lay on the beach chair, looked at the blue pool in front of him, and couldn't help but sigh.

Wei Guifei was eagerly serving Li Shimin on the side, eating Zhou Imperial Chef's latest masterpiece - yogurt ice cream.

"This is the boy's reverie of the sea, the sea is far away, the boy has never been there, but he yearns for it to the extreme, so he has to make one according to his imagination!" Merton found a plausible reason.

"If others have any ideas, they just think about it, but Lord Mo has turned his ideas into reality, this is probably the uniqueness of the Mo family!" Wei Guifei sighed.

Li Shimin also nodded slightly, the Mo family did give him too many surprises.

"Your Majesty, the concubine also wants to build a swimming pool in the palace!" Wei Guifei was obviously conquered by this beautiful scenery, and the pool in front of her was close to the Taiye Pool, which was obviously built for Li Shimin and the princes, how could the concubines and the princes share the same pool.

Merton also considered building two swimming pools at the same time, one male and one female, but even if the middle was separated by a wall, the sound of laughter could be heard clearly, which was also a big taboo and could not coexist, so in the end, he simply went all out to build this pool to the most perfect.

Li Shimin immediately set his eyes on Merton, and Merton hurriedly shook his head and said: "It is not suitable for Weichen to enter the harem, but the specific drawings have been handed over to the general as a prisoner, and I believe that according to the manpower in the palace, it is not difficult to copy this pool." ”

Li Shimin nodded and said, "Leave this matter to Pang De!" ”

"Yes!" Pound commanded.

At this point, Merton's mission has been completed, and he immediately resigns from the palace.

Walking out of the Suzaku Gate, Merton breathed a sigh of relief, Merton's summer retreat, swimming pool, and ice-making have all been introduced to the palace, but he didn't have the consciousness to recommend it to Li Shimin at all.

After all, the swimming pool, saltpeter treatment is only the rich and noble can afford to enjoy, it is logical to introduce it into the palace, and compassion is the clothing of the common people, the price is naturally attractive to ordinary people, and it is God to help, I believe that in this hot weather, Chang'an City may have been all the rage!

The method of swimming pool and ice making can only be spread from the top down due to the cost, and the compassion will also spread from the bottom up because of the cost, and when Chang'an City accepts such clothing, it will naturally be introduced to the palace.

Merton believes that over time, everything he does will be like a drop of ink falling into the water, leaving behind an ink color that will never be clear.
