The problem solved by the Jiaolong submarineDragon solved the following problems:
1. [Pressure resistance problem: The Dragon needs to overcome the huge water pressure on the seabed. For example, the water pressure in the Mariana Trench is more than 1000 times the standard atmospheric pressure.] China successfully resisted ultra-high pressure by using a 70-millimeter-thick titanium alloy shell, and the three observation windows made of pure glass on its structure could also withstand water pressure. This showed that China's technology in the waterproof aspect of submarines had reached the forefront of the world.
2. [The difficulty of controlling the rise and fall of a submarine: It must be able to sink and rise smoothly.] Dragon solved this problem with the help of ballasting iron. The ballasting iron began to provide negative buoyancy for the submarine to sink. After reaching a certain depth, it threw away part of the ballasting iron to make its specific gravity close to the density of seawater, reducing the working pressure of the propeller. After the operation was completed, it threw away the ballasting iron again to obtain positive buoyancy.
3. ** Communication problem **: Because electromagnetic waves are seriously weakened underwater, the submarine needs to transmit information using sonar, but there is a problem in extracting sound transmission signals in different seawater environments. Dragon's domestic sound system solved this problem. Its sonar could accurately send and identify signals, and it could also explore the surrounding fine terrain. At the same time, the domestic ultra-short baseline positioning system could provide underwater positioning and navigation services, and the equipment could broadcast the exploration process.
4. ** Life support problem **: Like a space capsule, a deep-sea vehicle needs water, food, and a circulatory system to ensure that the submariners can operate normally underwater. There were two oxygen supply systems inside Dragon, which could guarantee the safety of three people for 84 hours.

People solved the problem according to the enlightenment of dragonfly flightPeople had solved many problems based on the enlightenment of dragonfly flight:
- In the design of flexible robots, the flexible structure of dragonfly wings inspired the design of flexible robots.
- In terms of aircraft design and performance improvement, the dragonfly's flight method, including rapid flapping of wings, bending and stretching of wings, was used to design more efficient aircraft. Modern aerospace engineers tried to learn from dragonflies to design more energy-efficient aircraft. This was because dragonflies were extremely energy-efficient and could take off quickly, maneuver in the air, and hover for a long time.
- In the field of materials science, dragonfly wings were famous for their strength, toughness, and lightness. Their microscopic structure and biological materials were used to develop lighter, stronger, and more durable high-performance composite materials and reinforcements. The compound eye structure of the dragonfly was used to design various visual systems and image processing algorithms. The biological materials of its body were widely used in the fields of robotic technology, electronic equipment, and aerospace.
- In terms of motion control, the flight control mechanism of dragonflies had great implications for the design of autonomous aircraft and drone motion control systems. By studying dragonflies to adjust the speed and angle of their wings to achieve complex flight movements, it would help to better understand and achieve more natural flight control.
- In the field of biomedicals and machine learning, the eye structure of dragonflies inspired the development of biomedicals and computer vision algorithms. The learning ability of dragonflies also inspired the improvement of machine learning algorithms.
- In terms of gliding applications for micro-air vehicles (MAVs), the research results on the knot structure of dragonfly wings enhanced the knowledge of insect-inspired knot structure wings and promoted the application of micro-air vehicles (MAVs) in gliding flight.
- In terms of the direction control of the aircraft, a farmer in Guizhou was inspired by the change of wing angle to control the direction when the dragonfly was flying. He introduced an adaptable wing structure in his aircraft design, allowing the aircraft to control the flight direction more accurately.

The problem of all-out offense is incapable of being solvedHe didn't quite understand the exact meaning of the phrase " all of us are incapable of solving the problem ". If everyone was faced with a problem but did not have the ability to solve it, there could be many reasons.
On a personal level, they might lack the ability to control their emotions, identify problems, be flexible, give up at the right time, and continue to learn. For example, it was difficult to calmly think of solutions when they were emotional; they could not accurately grasp the core of the problem and only did useless work on the surface; their thinking was fixed and they did not know how to adapt; they were unwilling to give up the wrong direction because of sunk costs; or they lacked the awareness to continuously learn new knowledge and skills to deal with problems.
From a team or organizational perspective, there may not be an effective problem solving system. As mentioned in the Mckinsey Work Management Act, there may be problems such as rushing to do things without exploring the truth, only looking at the surface and ignoring the essence, lack of team combat thinking, or lack of strategic thinking ability to determine the right direction, lack of tactical architecture thinking to ensure execution, lack of big data results thinking, etc.
If he could clarify the specific situation of this question or rephrase the question accurately, it would help to give a more targeted answer.

How was the problem of Luo Yuheng's Hellfire solved?Luo Yuheng had no choice but to agree to become the state preceptor and guide Emperor Yuan Jing in his cultivation in order to extinguish the karmic sinflames with the help of providence. However, he had insisted on refusing to dual cultivate with Emperor Yuan Jing for many years. Later on, he learned from Daoist Priest Golden Lotus that Xu Qi 'an had the fate of the country, so he had been helping him and secretly observing him. After experiencing a series of things, he had acknowledged him in his heart. After that, the two of them officially became dao companions. After multiple dual-cultivation sessions, they gradually suppressed the karmic sinflames.
