Why did Hailong Douluo kill Tang San?

Tang San's fifth test of Poseidon was to challenge the seven guardians of the sacred pillar, and the dragon battle was the last level of the seven guardians of the sacred pillar. For Tang San, as long as he passes this level, it means that Poseidon will pass the fifth exam smoothly. As the last assessment teacher at this level, Hailong Douluo is naturally very strict. After all, for the Seven Pillars Guardian, their duty is to guard the seven pillars of Poseidon Island and wait for Poseidon's return. However, as Poseidon's successor, Tang San was clever in the challenge, and this opportunistic behavior was not recognized by everyone.

In other words, Tang San's current ability is not worthy of virtue!

Because of this, poseci was dissatisfied with Tang San. However, Poseidon's fifth test was to take charge of the seven sacred pillars of Poseidon Island. Now, this is the last checkpoint. Therefore, before the examination, poseci will find Hailong Douluo to remind Poseidon Douluo again. The evaluation of Tang San is related to the future of Poseidon Island. Please be careful with the dragon fighting Luo.

This is also the case. So, after trapping Tang San with a "ground explosion star", Hailong Douluo resolutely launched the ultimate killing. His purpose is simple. That is, if Tang Santing passes, it means that he does have the potential to become Poseidon. If Tang Santing fails, it can only be death, no wonder anyone.
