Lin Wan’er, after returning to Jinling and to Purple Mountain Villa, had not stepped out of the door at all.
The courses at school were very full, but Lin Wan’er already felt fatigued with school.
The reason she had gone to Jinling University to study in the first place was mainly to search for and get close to Ye Chen. Later, when she found Ye Chen and shared all her secrets with him, school became dispensable.
After returning from Japan, her emotions entered a depressive phase. She felt she no longer had the energy to maintain the identity of a university student, so she asked Qiu Yingshan to help by putting in a word, applying for a leave of absence from Jinling University on the grounds of illness requiring recuperation.
With Qiu Yingshan’s connections, the school leaders naturally approved it immediately, so Lin Wan’er stayed within Purple Mountain Villa without stepping out.
In the blink of an eye, several days had passed.
During these days, Ye Chen was almost the same as Lin Wan’er. He had been staying in the mid-mountain villa at Champs-Elysees Hot Springs and had not stepped out even half a step.
During this time, he had also been trying to seclude himself in cultivation, but because his mind was too preoccupied, the effects of the seclusion were not very good.
He hoped that Li Yalin and Lin Wan’er could bring him good news, but Li Yalin’s reported progress had always been less than optimistic, and Lin Wan’er had not sent any messages at all.
During the days Ye Chen was in seclusion, Li Yalin had already flown from Australia to China.
In Australia, he had not been able to track down Tang Sihai’s whereabouts. Although he knew that with full effort in digging, he could certainly find clues, it was tantamount to fishing a needle from the sea.
Fishing a needle from the sea, with the needle in the sea, it was not that it could not be fished out, but the cost was too great, even beyond human capability.
To avoid wasting time, he decided to give up on Australia and use China as the entry point.
Solving a case is actually a process of screening, and the difficulty lies in the base number for screening.
Any case is done by people. Speaking irrationally, checking all eight billion people on Earth would definitely find the person you want to check.
But the problem is that no one has the capability for such screening.
Not to mention eight billion people, even eighty thousand is hard to screen thoroughly. You can only do a few rough sieves and then fine sieves. If the rough sieve does not miss anything, it is good; once it misses something, almost all subsequent work is wasted.
Li Yalin had been in the police for many years and not every case could be solved. Some cases simply could not be cracked no matter how they were investigated.
When he spent several days and found no clues related to Tang Sihai, he realised that Tang Sihai’s level of precaution and the professionalism of his team behind him were extremely high. Continuing like this, there might not be any progress in a year and a half.
Thus, he returned to the country and met Su Ruoli.
With Su Ruoli’s help, he brought the He family members and the ninjas from the Ito family to investigate the clues of Xiao Churan and her family’s departure.
If checking Tang Sihai in Australia was like searching for a leaf boat in the vast sea, then checking Xiao Churan and her family in China was like finding a specific mung bean in a pile of mung beans.
Li Yalin felt immense pressure but could only start checking vehicle by vehicle.
However, this process would be extremely lengthy, so he also reminded Ye Chen to prepare for a protracted war.
However, it was not entirely without opportunity. At the same time, he fed the image data of Tang Sihai and Xiao Churan’s family of three into the AI model, combined with the ground net system, to set up surveillance worldwide.
