The scorching sun hangs high.


    After Tang Hao gave the order to remove the armor, the soldiers didn''t have much scruples about it.


    Lift the heavy armor one by one, and the weight is light.


    Chumo is even more exaggerated. He simply takes off his cotton padded clothes. He is not satisfied. When he is about to take off his inner shirt, he is stopped by Tang Hao.


    "You are really a man who is not afraid of things!"


    "To let you remove your armor is just to delay the passage of sweat. Are you ready to be naked?"


    "Aren''t you afraid of sunburn?"


    The plateau has a high terrain and the air is much thinner than the plain.


    But just like this, a lot of ultraviolet radiation has become the No. 1 killer of damaging the skin!


    Chumo, an ancient man, looks at Tang Hao''s face and grins.


    "Hey! I''m a rough man. I''ve been used to guarding the border for a long time."


    "Can this solar energy still sunburn? I''m not as delicate as a big man."


    As soon as the voice fell, Su Qingjie also coaxed.


    "Brother Tang, you cover your face with a scarf. Are you afraid of being scorched by the beautiful girl at home?"


    Then they looked at each other and laughed.


    Tang Hao didn''t bother to explain the problem of ultraviolet rays with them. For this kind of thing, explaining to them is like casting pearls before swine.


    Looking at Chumo, who is pulling his clothes off again, Tang Hao looks serious and stares.


    "Stop fooling around! This is an order!"


    "If the whole army is like this, what will our barracks look like?"


    Seeing that Tang Hao was angry, they didn''t dare to say anything more, and narrowly smiled.


    Chumo sees Tang Hao''s serious face, ponders for a moment, and asks.


    "Brother Tang, you just drew on the ground with a tree stick, saying it can be used as a basis to distinguish the position, can you?"


    Tang Hao listened to him ask about it and explained it roughly.


    "These two points are used as marks. This is the ancient method recorded in ancient books. Few people know it."


    "Immediately, mark the top of the shadow, wait for the shadow to shift after half a cup of tea, and then mark it."


    "Take two points to connect and make a cross sign. One side of the sun is south and the other side is north. Now we''re going east."


    "Although we can''t guarantee accuracy, there is no doubt that we will return to the territory of the Tang Dynasty if we keep walking like this."


    It was the first time for the two young people to hear this way. They shouted that they learned another move today.


    In fact, the way Tang Hao said was more common in later military barracks, but he lied that he saw it in ancient books.


    Anyway, since I came to the Tang Dynasty, I have told no less than 70 or 80 lies, nor less than 30 or 40.


    It doesn''t matter if there is such a painless lie.


    The desert evening came very early, and Tang Hao''s army finally arrived at dusk.


    According to the statistics of the army, the number of comas soared.


    Unexpectedly, in two days, people who haven''t dropped water will have big things sooner or later if they go on like this.


    Looking at the limp soldiers, Tang Hao ordered.


    "Put the helmet vessel on the ground, hang the sword on it, and point the blade and sword tip directly at the center of the vessel."


    After hearing the inexplicable military order, Chumo walks up, cracks the pale bleeding lips and asks.


    "Brother Tang? Why?"


    "Look at this..."


    He raised his arm and pointed to the utensils in the open space.


    "I''ve heard of a general burning incense and praying for fish in ancient times. I''ve also heard of the man throwing money and asking for directions. Which one are you playing?"


    Some soldiers who were close to me had the same doubts.


    They also have such doubts in their hearts. They want to say that they pray for rain, but how can this scene look like it?


    Why don''t you, Tang Hao, hang these swords just to demonstrate?


    Tang Hao doesn''t explain much. He goes forward, touches the sword and waves to Chumo.


    "Come and touch it. How does it feel?"


    With a touch of doubt, Chumo pastes the back of the knife and starts to feel cold without any other feeling.


    "Isn''t this an ordinary knife point?"


    "What''s the difference?"


    Licking the dry cracked lips, Tang Hao found that his saliva seemed to be very stingy, and he couldn''t even wet his lips.


    He patted Chumo on the shoulder with one hand and pointed to the utensils under his feet.


    "This is what we pray for water from heaven first. We can drink sweet water early tomorrow morning."


    Chumo looks at the empty helmet and his eyes are bigger than the copper bell.


    Isn''t that a joke?


    Today''s emperor prays for rain and blessings, but also puts on three sacrifices.


    If the Taoist priest doesn''t pray for rain, he also puts on incense wax and reads a password. It''s not pious, but at least there can be a decent ceremony.


    What is this?


    No sacrifice, no ceremony, just do it like this, can there be water?


    Facing Chumo''s stunned face, Tang Hao can clearly know his inner thoughts without asking.


    "You! There are many things you don''t understand."


    "The specific heat capacity of sand and stone is large, coupled with the unique temperature difference in the western regions, it will certainly form moisture, which will condense into dew in case of cold swords."


    "There is a saying called gathering sand into a tower. I want to use this little dew to merge into half helmet water."


    After all this, Chumo is in a blind spot.


    Tang Hao, who looked at an expert and was full of endless confusion in his dementia eyes, asked after listening to Bala''s stop for a long time.


    "What is the specific heat capacity?"


    "What is the temperature difference?..."


    "And what is that condensation..."
