"What is that, why have I never heard of it, what's the use of you asking for this?" Liang Yu looked at Liu Yu suspiciously.

"The blower increases the air flow, and when the firewood is burned, it needs a lot of air to burn it sufficiently. The air flow generated by natural convection is not sufficient to meet the needs of smelting. So I need a blower so that I can smelt the ingots faster and better. Liu Yu explained.

"Where did you learn this, how come I have never heard my grandfather say that he is the best smelter in the empire, I have studied with him for so long, why have I never heard these names you say? I don't understand what you said at all, can you explain it in detail?" Liang Yu rubbed his head with a blank expression on his face.

"Isn't there anyone in the empire who understands such a simple principle?" Liu Yu asked in astonishment, in Liu Yu's heart, this is ordinary knowledge, no one in the empire understands, and he can't help but think in his heart, where does the secret in that cave come from?" "Why don't you go to the smelting furnace with me, and I'll show you, and you will understand it more easily." After speaking, he took Liang Yu's hand and hurriedly walked towards the courtyard where the smelting furnace was located. Liang Yu's spirit was still in a trance, and he didn't find it, so he was pulled over by Liu Yu.

The two walked towards the courtyard where the smelting furnace was located, and before they could enter the courtyard, Liang Yu was stunned again. I saw that the outside of the yard was full of ore and firewood, and it seemed that all the stocks in the warehouse had been moved, how did he do it in such a short time? "How did you, how did you move all of this in such a short time?" Pointing to the ore outside the courtyard, Liang Yu's words trembled a little.

Hearing Liang Yu's trembling voice, Liu Yu suddenly realized the mistake he had made, and subconsciously let go of the hand that had been holding Liang Yu. She was so careless that she had moved so many things at once, no wonder she was surprised, she was only thinking about how to save time, and forgetting all the secrets that might reveal her by doing so.

When Liu Yu let go of his hand, Liang Yu found that his hand had been being pulled by this young man, and his face was flushed for a while. Hurriedly lowered his head and fiddled with the corners of his clothes, not daring to look at Liu Yu again. There was also turmoil in my heart.

Looking at Liang Yu who hung her head, Liu Yu's heart was also worried, she had discovered her secret, if it was passed on, what should she do? Looking at Liang Yu, Liu Yu was in a dilemma, she couldn't do anything to hurt her just to keep her secret, right? Thinking of a teacher who was so good to herself, Liu Yu really couldn't do this.

sighed in my heart, and bet on this, anyway, I have a backhand. "This is a secret of mine, and I hope that Sister Liang Yu can keep this secret for me. Liu Yu stared at Liang Yu and said, "Let's go to the yard first, and I'll explain the blower to you." After speaking, he walked into the small courtyard first.

After hesitating for a while, Liang Yu also followed Liu Yu into the courtyard. The two stood still in front of the smelting furnace, Liu Yu re-lit the smelting furnace, then found a pipe, put the pipe under the firewood, and blew the pipe. As Liu Yu continued to blow into the pipe, the burning of firewood became more vigorous.

Looking thoughtfully at the raging flames, Liang Yu fell into deep thought. Why is there such a miraculous change? Liu Yu stopped after blowing for a while, and when he saw Liang Yu's contemplative face, he stood aside and did not disturb her thinking.

After a long time, Liang Yu came back to his senses: "The wind is the power of the wind, I understand." Liu Yu, you are really smart, how did you find out?" Hearing Liang Yu's appreciation, Liu Yu's heart was puzzled, how could he be so smart, he just learned it from that cave. When it comes to Liang Yu, she can understand the key to just watching herself blow on the fire for a while, she is smart enough. "It's just a serendipitous discovery, it's not worthy of Sister Liang Yu's praise, since Sister Liang Yu has understood, can you help me with this?" Looking at Liang Yu's excitement, Liu Yu asked with a smile.

"This is easy to do, I will go to my grandfather, I believe he will be very happy to know, with his experience, it will be designed and manufactured soon." You wait here for a while, and I'll be right back. After Liang Yu finished speaking, he left in a hurry.

Finally, Canno City was in sight, and there was still an hour left before the allotted time. Zhang Tianqi's heart that had been hanging finally fell. For him, the biggest gain is not that he can successfully pass the first round of assessment, but that he has discovered the improvement of the "Yijin Sutra" on his body, and he can achieve such good results in a short period of time after studying, and he can't imagine what will happen if he continues to cultivate. After following everyone into Canno City, coming to the finish line, and submitting his number plate to the examiner to complete the registration of the assessment results, Zhang Tianqi did not sit down and rest like others. Seize the time and continue to practice the "Yijin Sutra" exercises. Consolidating the results of his cultivation.

An hour later, the first round of assessment of the combat department was over, and the top 1,000 in the first round had been selected. Zhang Tianqi ended up in sixth place. Zhang Tianqi is still very satisfied with this result, after all, there is an assessment later, and there is no need to show all his hole cards.

Tomorrow there will be a second round of examinations in Canno City, and all candidates will be accommodated in the accommodation provided by the Bokan Military Academy. The second round of assessment is shooting, which is divided into infantry archery and mounted archery, with ten arrows each, and the results of twenty arrows are added together to calculate the total score.

Sitting on the bed in the dormitory provided by the Bokan Military Academy, Zhang Tianqi did not rest early. This day's assessment brought him a lot of unexpected gains, making him more confident to meet the next challenges, and at the same time he also had an inexplicable good impression of Liu Yu, if it wasn't for the "Yijin Jing" exercises he gave him, this first round of assessment would not be so easy. Archery has always been his strong point, and after practicing with his grandfather for so many years, Zhang Tianqi is still very confident. In addition, with the assistance of the exercises, I believe that you can also achieve good results. After learning such a strong exercise, now Zhang Tianqi doesn't want to delay for a moment, and he can't wait to spend all his time on cultivation.

The Scouting Department was concentrating on the assembly area deep in the jungle, and the candidate who had been in the back at the beginning had already come to the front. He looked at the map in his hand and said to himself, "Judging from the current location, it is not too far from the end point, and it should not take long to reach it." The traps set by those examiners in the jungle are too obvious and not challenging at all, and I hope the next round of assessments will be interesting. I won't play with you anymore, so I'll go first. After saying that, there was no movement under his feet, and the person had disappeared.

In a corner of the assembly area, the two examiners in charge of the assessment were sitting there chatting with each other. "The quality of this year's candidates is good, the traps we set have no effect, and the speed of travel in the jungle is also very fast, and there are many good seedlings worth cultivating. One of the examiners said. "Yes, the reconnaissance department of our academy has always been very weak, and it has been pressed by several other colleges for many years, and it seems that there is hope for a turnaround this year. The other examiner continued. "Just rely on these useless things of theirs? I think it's better to forget it, it's not shameful enough to take out such goods, it seems that the heavy responsibility of the Everbright Investigation Department will fall on my shoulders in the future. A figure patted the two examiners on the shoulder.
