There are some first-class athletes in the national team, and sprinting is a relatively large event. As Xue Li's favorite disciple, Li Dai has gained many opportunities, so during his time in the national team, Li Dai's experience was a success.

Li Dai upgraded from the primary stage of a first-class coach to the intermediate stage, which requires a full 50,000 experience. If it were put in the past and continued to train those young athletes, it might have taken Li Dai to ten or eight years to upgrade. However, in the national team, Li Dai gained more experience, and the upgrade speed is not slower than before.

During this period, Li Dai also participated in some competitions, and the athletes won the rankings, and also gave Li Dai some experience rewards.

For example, in the National College Games, although the athletes' level is average, they are at least a national comprehensive sports meet. Yang Sijie's champion and Niu Guohong's third place gave Li Dai two thousand experience rewards.

For example, in this Asian Games, in the long jump final, Li Dai took the opportunity to help Fang Haiquan with massage to get Fang Haiquan back to his training list. Fang Haiquan then won the Asian Games championship, and Li Dai also received experience rewards.

Although Xue Li personally was responsible for the training of the relay race before, he has been in charge of Li Dai's training list. Yang Sijie won the Asian Games 100-meter sprint championship, and also gave Li Dai a large amount of experience rewards, which directly allowed Li Dai to accumulate enough upgrade experience. He upgraded from the primary stage of a first-class coach to the intermediate stage of a first-class coach.

"I finally upgraded again. I don't know what good things will be in the gift pack for this reward." Li Dai was immersed in the system. He couldn't wait to know what kind of upgrade reward he would receive this time.

"System, bring my gift bag!" Li Dai said.

"Okay, congratulations on getting the upgraded gift package." The system's voice rang.

"Wait a minute, I'm just upgrading from a first-class coach to an intermediate stage. Shouldn't I get an upgrade gift package? How could it become a big upgrade gift package?" Li Dai asked.

"I forgot to tell you that after becoming a first-class coach, upgrading will become more difficult, so the reward will be improved, and the upgrade reward has also changed from an ordinary upgrade gift package to a large upgrade gift package. In other words, you can get two rewards every time you upgrade." The system explained.

"One more prize!" Li Dai suddenly felt happy.

When he opened the upgrade gift package, Li Dai couldn't wait to look inside, but he found that there were two items inside. On the left was a book, which was definitely a new skill, and on the right was something similar to the badge of the shopping guide.

"What is this?" Li Dai took the lead in picking up the badge, a reward he had never seen before.

There are four big characters written on the badge: iron chain chain.

"Cable chain? This reminds me of the Battle of Red Cliffs during the Three Kingdoms, and Zhou Yu burned the chain ships. What exactly is this?" Li Dai asked.

"This is a title! Congratulations, I won the first title!" the system explained.

"What is the use of title? Is it only used to sound good, or is it a decorative product, or has a substantial effect?" Li Dai continued.

"Of course it has a substantial effect, and each title can bring some substantial improvement effects." The system explained.

"What's like a halo?" Li Dai sounded the halo on his head.

"You can think so, but titles and halos do not conflict. You can equip titles and halos at the same time, and enjoy the benefits brought by titles and halos at the same time," the system explained.

Li Dai has always been resentful of having to equip one halo at the same time. Now that there is another title, Li Dai thinks it can make up for the shortcomings of having only one halo.

The system then explained: "In addition, there is another very important difference between title and halo. The improvement brought by halo is positive, and titles will not only have positive effects, but may also have negative effects."

"I just knew it wasn't that simple!" Li Dai couldn't help but complain.

"If it's all positive effects, then won't the title overlap with the halo?" The system then explained: "Take the title of 'crack chain' you have now obtained as an example. After equipping the title, the degree of tacit cooperation between the athletes on the list will increase significantly!"

"The degree of tacit understanding of cooperation increases, and this effect sounds very good. Sports such as basketball, football, and volleyball can definitely be used; doubles for tennis, badminton and table tennis also require cooperation between teammates; in addition, for example, multiple people can also be used! In this way, as long as it is not a single-player event, the effect of this "crack chain" is quite extensive."

Li Dai paused and then asked: "The degree of cooperation and tacit understanding should be the so-called positive effect? ​​So what are the negative effects?"

"The negative effect is that after being equipped with a 'crack chain', athletes will also influence each other. For example, if one of them is in good condition, it can also affect the other players' states as well." The system explained.

"Is that the poor condition of an athlete will also affect other athletes and become in poor condition?" Li Dai asked immediately.

"Not done. Strictly speaking, this is not a complete negative effect, but can only be regarded as a double-edged sword. For example, in a basketball game, if a player feels excellent and makes continuous shooting, his teammates will also be affected and the feel will become better. On the contrary, if a player keeps hitting irons, his teammates will also be affected and will not score goals." The system explains it very thoroughly.

Li Dai nodded. The effect of the teammates' mutual influence is quite realistic. This situation often occurs in real games. Many times, the shooting sightseeing star seems to be contagious, especially for teams that rely on shooting. Everyone should shoot accurately and take away their opponents easily with a three-pointer rain. If they are not accurate, everyone will not score any goal. If you miss two shots, I miss three shots, and the game will naturally collapse.

"I am a track and field coach now. With my current stage, I can't use it for the time being, so don't rush to get equipment!" Li Dai turned his eyes to the skill book again.

"I have had weight loss exercises, fat loss exercises, relaxation massage, and rehabilitation massage before. I don't know what it was this time." Li Dai looked carefully and saw four big words on the cover of the golden skill book:
Chapter completed!
