Half a month later, counting the 26th day of departure from Spring City, the team led by the military has now entered the HLJ territory, and the military radio station, which has been without a signal just two days ago, finally has a signal.

The military led by Wang Haisheng has already made contact with the garrison troops in the HLJ area, and the HLJ troops have also sent some soldiers to meet as soon as possible, and if nothing else, the two sides can meet this afternoon.

In the camp where he was stationed, Zhao Guizhen hurriedly ran back to the car as soon as he finished eating.

There are countless mutant beasts and zombies encountered along the way, and the largest one is a small corpse tide formed by nearly 10,000 zombies, taking advantage of the dark night to attack the migration team.

In that battle, Zhao Guizhen's maids also went out together, which eliminated this wave of small corpses.

Of course, so many battles are not a bad thing, at least Zhao Guizhen has more and more materials in his hands, and Wang Haisheng also waved his hand to give Zhao Guizhen the crystals and various materials he got in exchange for weapons.

For this reason, all the weapons and armor in Zhao Guizhen's hands were all replaced, and he also made a lot of money.

"Black velvet flower, ghost head snake crystal, shadow stone, yin banyan wood" Zhao Guizhen would carefully check every material he picked up.

Zhao Guizhen, the advanced key of the shadow apprentice, has been thoroughly digested, and now his body is also at its peak, and today is the moment for Zhao Guizhen to use the key of the intermediate professional and advance to the intermediate professional.

The situation in Northeast Frost Township is different from that of Chuncheng, the two sides don't even have any comparison, the number of soldiers led by Wang Haisheng in Chuncheng is small, and the situation in Chuncheng at that time is quite serious, and there are no conditions, so this will be the situation that Wang Haisheng and others know that taking crystals can be advanced, but how to configure the advanced key is not clear.

In the first week of the apocalypse, all the garrison troops in the HLJ area entered the city and controlled the situation in the city at that time.

Not to mention the preservation of various buildings, at the same time, the internal industry, light industry, various high-tech industries, and scientific research industries in the city are quite complete.

How to advance, Northeast Frost Township already has its own research and development path, Zhao Guizhen remembers very clearly, in the second week of his previous life, there were already junior professionals in Northeast Frost Township.

In this way, since Zhao Guizhen wants to gain a foothold in Frost Township, it is imperative to advance to an intermediate profession, and only if he advances to an intermediate profession, he can completely ignore the threat of thermal weapons to him.

Otherwise, once he was fired with a large-caliber sniper rifle or heavy machine gun in Frost Township, Zhao Guizhen would have to fight on the street, and only when he advanced to an intermediate professional could he be regarded as having real self-preservation.

A special and ominous-looking material was placed in a special crucible by Zhao Guizhen, which was different from when the materials for junior professionals were allocated.

The advanced key of an intermediate professional is not simple, Zhao Guizhen condensed a cloud of shadow power and infiltrated into the crucible, and a steady stream of shadow power was extracted by him, and then put into the crucible.

In fact, there was an unwritten unspoken rule in the previous life, the optimal proportion of advanced keys is often the best only if you configure it yourself, after all, the abilities controlled by each person are slightly different, and only your own is the best.

Although the advanced keys bought from the store are convenient, they are still different from their own configuration after all, which is also something that Zhao Guizhen once heard from a preparation master by chance, but at that time, Zhao Guizhen had already advanced to an epic professional, and it was too late to regret it.

But now it's different, since Zhao Guizhen knows this unspoken rule, he naturally won't use the advanced key prepared by others.

Time passed silently, and after half an hour, Zhao Guizhen's face gradually turned pale, and he continued to extract shadows for half an hour, which was about to reach Zhao Guizhen's limit.

Sweat fell like rain, but Zhao Guizhen's movements did not stop, the more shadow power was infused at this time, the better the quality of the key he configured.

The familiarity with shadow abilities gives Cho an edge in this regard, and the average junior professional may have reached the limit by ten minutes, while Cho has exceeded it by three times.

"Not enough, still not enough" Zhao Guizhen's steel teeth clenched, and more and more shadow energy was poured into the crucible, and in the small crucible, all the materials had been fused with the shadow ability.

Inky black shadow energy swirls inside the cauldron, occasionally emitting bubbles that make people shudder as if they were a witch's potion.

The last bit of shadow energy was poured into the crucible by Zhao Guizhen, and from the beginning to now, Zhao Guizhen has held on for fifty minutes, more than five times that of a normal professional!

And this is precisely the optimal ratio, the truth of too much also exists, five times is exactly the limit that Zhao Guizhen's body can accept, if there is more, then Zhao Guizhen's body can't bear it at all, but it will kill Zhao Guizhen.

As soon as his feet were weak, Zhao Guizhen hung without falling, and endured the feeling of weakness and soreness, but it was not over yet, and there was still one last step left to be carried out.

The killer appeared in his hand, Zhao Guizhen slashed at his wrist with an expressionless face, and the red blood splattered into the crucible, and Zhao Guizhen watched as the crucible was soaked with his own blood.

Holding the gauze around his wrist, Zhao Guizhen looked at the crucible without blinking, the red blood was gradually absorbed by the shadow energy, and the shadow energy in the crucible contracted rapidly and gradually changed.

For about four or five minutes, there was only a pitch-black bead left in the crucible, Zhao Guizhen couldn't wait to pick it up, the bead was cold and piercing, as black as ink as if it were a black hole, if you looked closely, you could see that there seemed to be a bloodshot flickering inside the bead.

"It's done!"

Seeing this, Zhao Guizhen finally breathed a sigh of relief, and the heart that had been hanging in his throat was finally put down.

Unlike in his previous life, the mid-level professional chosen by Zhao Guizhen this time was not the skinner in his previous life, although it was a good route to advance from a shadow apprentice to a skinner.

But this time, the resources in Zhao Guizhen's hands are far from being compared with those in his previous life, so he naturally will not choose this kind of popular profession again.

Night scout, the intermediate professional chosen by Zhao Guizhen this time is a very rare night scout, the reason why he knew this profession in his previous life was because of an accident, Zhao Guizhen had advanced to a senior professional at that time, but once in a battle facing a night scout, Zhao Guizhen was beaten by the other party's strange means and could only protect himself.
