Disagree.
Basically, infinite speed is the speed that makes an object can travel anywhere within 0 seconds, The application of the word "reaction" in infinite speed will reap contradictions, because literally reaction is a person's stimulation in knowing the essential that comes to "Something" this way someone certainly cannot know the existence of an infinite speed object that approaches "Something" The application of the word Reaction also generally means that the speed it has is faster than an object that is close to "Something" where actually the Infinite speed baseline does not seem to exist, because 0 seconds is Absolute which means that it is really the top speed that still uses the concept of time in getting it.
In addition, there are some words that are less relevant in indicating the speed of the spear qualified infinite speed.
The achievement above, has seriously denied that the spear is able to move within 0 seconds, this narrative is not a point of view from an aegis opponent who has a perception that the spear seems to disappear but a series of narratives that show the main plot that occurs, which means that the spear still needs time to travel
How did Lay perceive his gaze in response to the spear attack, which stated that he could see the spear attack coming towards him, This has completely denied his own infinite speed, at least the human eye can only see the speed of the object by 35m/s
