In order to complete the skill upgrade, Su Rui can only eat non-stop.

Now he doesn't know how much he has eaten, and he is not in the mood to eat, all his thoughts are on eating, and there is no way to pay attention to other things.

It is estimated that at this time, if someone punches Su Rui, he may continue to eat instead of fighting back immediately.

After he is full, he will give the other party a beating, and he should not fight back immediately, not because he is calm, nor because he is magnanimous, but it is difficult for him to fight back.

Because, now Su Rui is very hungry, he has no strength, the only strength still needs to be used on eating, if he fights back, not only will he not be able to win the other party, but he will starve himself unconscious, which will outweigh the losses.

Because of this, if any accident occurs at this time, as long as it is not life-threatening, or something particularly important, he will not be in the mood to pay attention to it, even if he is beaten, he can't stop eating, he still has to continue eating, only when he is full, he can do other things, and he can do well, if he is not full, then he can't do anything.

However, Su Rui will make full preparations before upgrading his skills, and after making sure that there are no problems, he will start the skill upgrade.

This kind of unexpected situation is basically impossible.

After all, when Su Rui was upgraded, there was no one else around, and the door was locked for him, how could he be beaten, this possibility was so low that it was almost impossible to happen, and it was just a meaningless hypothesis.

While eating, he also noticed a problem.

Su Rui found that when he was leveling up, he was more and more able to eat, eating more and more each time.

If it was at the beginning, when he first started to upgrade his skills, he would have already eaten enough by now, and his energy had been replenished, so he didn't need to eat as much as he did now to complete the upgrade.

However, Su Rui thought that this should be as the level of the skill increases, he needs more energy, or his physical fitness is getting higher and higher, and he will need more and more energy when he improves, which is also very normal, so if he also wants to improve his physical fitness, of course, he will consume more energy than before, so he needs to eat more food to replenish his energy.

In this way, it is possible to explain why his leveling up, the food required, is higher and higher each time.

When Su Rui ate until his mouth was already sore, the hunger finally disappeared slowly, and his eating speed slowed down, not as crazy as before, but eating little by little, and he could chew it, chew it slowly, and he wouldn't eat so fast and so quickly.

Eventually, when the hunger pangs are completely gone, replaced by fullness, he stops eating.

At this time, Su Rui's swimming skills have also been upgraded, and now he has level 8 swimming skills, and correspondingly, his physical fitness has also improved by two points, which is also a very good harvest.

How much can the eighth-level swimming skill be stronger than the seventh-level swimming skill, and how much it has improved, he is not clear for the time being, and there is only a vague concept.

But Su Rui has two improvements in physical fitness, but he has a very obvious experience, he can find the changes, there are not a lot of changes in all aspects, very clear changes, he feels that his strength has improved a lot, and there are also a lot of improvements in other aspects.

Physical fitness is the average of the five data of strength, speed, endurance, coordination, and agility, and the improvement of physical fitness often represents that these five aspects have been improved, but the level of improvement is different, which is determined according to different skill upgrades, mainly to see the upgraded skills, which aspect is biased, and the improvement in this area will be the largest, on the contrary, the improvement will be the smallest.

Swimming skills are a relatively balanced skill, which happens to improve on average in the five aspects of strength, speed, endurance, coordination, and agility.

Before the upgrade, Su Rui had 151 points of stamina, while 152 points of strength, 186 points of speed, 155 points of stamina, 125 points of coordination, and 137 points of agility, after the upgrade, his physical strength increased to 153 points, while the points of strength were 154 points, 188 points of speed, 157 points of stamina, 127 points of coordination, and 139 points of agility.

This is equivalent to strength, speed, endurance, coordination, agility five aspects, all improve two points, this kind of improvement is indeed very balanced, belongs to the all-round development, and do not want other skills, biased to one aspect.

Su Rui's strength, speed, endurance, coordination, and agility are five aspects, of which there are high and low, the highest data is speed, which has reached 188 points, and the lowest is coordination, which is 127 points.

But no matter which aspect is good, compared with the data of ordinary adults, it is much higher, even if it is the most coordinated, it is also the same, more than ordinary people, not to mention the highest speed of data, compared to ordinary people, it is even stronger, and the gap is very large.

In these five aspects, even professional athletes may not be able to compare with Su Rui, and most of them are below this value.

Therefore, in terms of physical fitness, he is far ahead, which makes his physical fitness much stronger than that of professional athletes, which is why he participates in competitions so frequently, but he can still cope with it, which is inseparable from his high physical fitness.

After upgrading, Su Rui's physical fitness has increased by two points, which doesn't seem to be much, but the improvement is still very large.

It can be said that with these two physical improvements, he is more confident in the next games, thinking that he can do better, and he is a little more secure than before.

Moreover, Su Rui has not only improved his physical fitness, but most importantly, the improvement of his professional skills, which is the most helpful.

Physical fitness determines the lower limit, but professional skill determines the upper limit.

This is like a pistol, in the hands of ordinary people, it must not exert much power, but in the hands of sharpshooters, it can be able to achieve 100 shots, so as to exert the maximum power.

And vocational skills are like this, you can use the best way to play to your strengths, so as to achieve the best results.

Although Su Rui didn't know the gap between the eighth-level swimming skills and the seventh-level swimming skills, he believed that the improvement would definitely be not small, and the gap should still be quite obvious, but he didn't know how big the specific improvement was.

Anyway, with these eighth-level professional skills and 153 skills, he feels more confident in the next competitions and can achieve better results.

Moreover, Su Rui believes that after upgrading the skill, the gain will definitely be greater than the gain before the upgrade, and the gap must be higher than 10 million faith points, which is almost no problem.

The better the results, the more faith points will be generated, and in this level of competition, the difference must be far greater than 10 million points.

Therefore, Su Rui still believes that this upgrade will not suffer a loss, and he will definitely be able to easily earn back this 10 million faith points.

What's more, 10 million faith points, in exchange for two points of physical improvement, is actually earned.

If such an opportunity is placed in front of some people and let them choose, most of them will choose to do so, and after the physical fitness is improved, the harvest will definitely be far greater than 10 million faith points.

Therefore, Su Rui does not have to worry about whether it is worth it in this upgrade.
