(7)Master of Passion
(8)Dr. Lim Yong-han, who is looking into the hole he worked hard on there
(9)What is this hole
(10)The second story
(11)Miltok is impossible to achieve 3-year-old Castle Attack
(12)Out of about 40 water polo
(13)Master’s eye-catching Alumni Water polo
(14)It’s the drain of the castle!!!
(15)Miltok is impregnable three years old
(16)Among the most acidic structures
(17)The reason I pay attention to water polo is
(18)Why do you keep your eyes on this place
(19)First of all, this water polo is located in one part of the wall
(20)It’s not installed
(21)Miltock Irresistible Three-Year Acid II
(22)for smooth drainage
(23)water polo located throughout the castle
(24)o Installation throughout the walls for smooth water discharge
(25)It’s already done
(26)The problem is
(27)Miltock Irresistible Three-Year Acid II
(28)A double-edged sword!!
(29)the invasion of the enemy
(30)The best place is also water polo
(31)A lot of the castles have been penetrated by the enemy through this water polo
(32)They were captured because of it!
(33)The reason why this water polo is troublesome is because
(34)Miltock Irregular 3-year Acidic II
(35)both East and West
(36)If you block it, the castle will collapse
(37)a headache that opens up to the enemy’s sting
(38)If you don’t have it, you’ll be filled with water, so you’ll collapse quickly, and you’ll go
(39)If you make it, the enemy invades you
(40)It was a real headache
(41)※The first provincial governor of Horan Joseon at the time of Jeongmyo
(42)The troops infiltrating the special waters of the Hugeun Army
(43)I was captured because I couldn’t stop him
(44)So the method Silla chose for the construction of Samnyeonsanseong Fortress was
(45)Three Years II Acidic acidity
(46)It is solid with a support stone, and despite the west wall, it is characterized by three-year-old fortresses
(47)degree
(48)Maintain a high 50 degree slope
(49)First, make a slope about 50 degrees!
(50)And the most important thing is this!
(51)impregnable and irresistible
(52)water polo characteristic 의
(53)a curvy internal structure
(54)It’s not a straight line
(55)Like this
(56)Made into a curved structure like this!
(57)No matter how much you look for it, how it was and how it was reflected
(58)Shape
(59)There is no information such as pictures or pictures
(60)Yes, a little bit, I understand that personally, I’ve already told you about the blockage
(61)I’m going to give it to you. He’s determined from his positionThe important thing is that the bent structure
(62)B
(63)by the way
(64)The reason why we design water polo like this is because
(65)Three-Year Mountain Fortress
(66)The reason why water polo is bent
(67)The strength of the draining water
(68)Design for regulation
(69)○○ To control the strength of water
(70)The greater purpose is
(71)If you don’t have it, you can crawl outAlthough the water polo of Samnyeonsanseong Fortress has a slope, it is only a little cumbersome and can penetrate as much as possible
(72)But if it’s bent to the inside of the aisle
(73)the decisive reason why water polo is bent
(74)Even if a person crawls in
(75)You can’t carry a weapon like a knife spear
(76)In case of infiltration, block the enemy’s main weapon possession!
(77)And because of this winding structure
(78)Another decisive reason why water polo is bent
(79)”The news of the enemy in front of you
(80)Don’t let the enemy who follows you know
(81)To win the war
(82)Always divide the enemy’s army! Keep the battlefield out of sight in front of the oars!!
(83)The enemy’s gaze bar was refined, which prevented the candidate from being actively delivered to the soldiers in the room! lol
(84)After listening to Dr. Lim Yong-ran’s explanation, a camera director saw the confirmation for the second time in a while
(85)II Acidic Acid
(86)The production team learned a lesson
(87)Hey, seriously
(88)I can see it out there
(89)Three-year-old Sanseong Fortress
(90)a proud master
(91)It’s definitely bent
(92)Miltok Irregular 3-year-old Sanseong
(93)※We couldn’t take a picture of the inside of the waterway, but it was really bent※It was confirmed that the sound was bent even though it was not filmed because it went inside the fire! lol
(94)with a stern door
(95)The way these water polo are designed is twisted
(96)I’m tied for 111
(97)I saw it in person at the time of the trip
(98)the curved structure of the Greek Acropolis
(99)Pure food, second, Yayagimil Tok, I’m not good at it. 3-year-old acid II
(100)This time, to India
(101)Scientifically designed water polo for a variety of strategic reasons
(102)It is also confirmed in Greek and other countries’ castles! There are castles that are designed vertically
