Because it has always maintained a cooperative relationship with the Xu family, the raw materials for the production of the second-generation golden seed medicine in the underground research center are not very sufficient, but they are not too short.

Although Zhang Haiyan's side shifted the focus of his work to the research of the Thunder Quenching Device, the production of the second-generation golden seed elixir has never stopped.

Although the female soldiers of the Fire Phoenix have only used the potion twice so far.

But this thing has no effect on the king of soldiers.

Based on the current state of the female soldiers, most of them should be able to complete the breakthrough after completely digesting the effects of this second potion.

In this way, the Fire Phoenix Special Base can naturally accumulate some Golden Seed second-generation elixirs.

If the Fire Phoenix Special Base does not recruit special combat teams for the time being, then these potions will basically not be used for a long time.

When the time comes, these potions will naturally be able to be traded.

For the current Zhao Han, there are some things that are still useful.

For example, treasure medicine.

To tell the truth, the treasure medicines that Zhao Han had obtained from He Zhijun on the military region through trading before, and Zhao Han directly used them to cultivate and absorb the pure life energy in them, which was actually a bit wasteful.

Although it is fast and convenient to cultivate in this way.

But these treasured medicines are actually better to keep for later use.

For example, if Zhao Han draws an experience card with alchemy or alchemy skills, these treasure medicines are excellent alchemy materials.

For example, when Zhao Han was in urgent need of a lot of energy, these treasure medicines were used for emergency purposes, which was better than wasting them in ordinary cultivation.

His own cultivation is not in a hurry.

And with a little time and energy, to find a place where heaven and earth are bellied, the speed of absorbing life energy is actually not slower than cultivating with treasure medicine.

Treasure medicine is precious, it is needless to say.

However, for people, the second generation of Golden Seed Elixir is more valuable.

The fundamental reason is that when others hold treasure medicines, they can only be used as medicinal materials with excellent efficacy.

However, the elixir of the Golden Seed has a very magical effect and can increase strength.

Therefore, when the time comes, as long as Zhao Han says that he is willing to take out the second-generation elixir of the Golden Seed in exchange for the treasure medicine.

Presumably, the special bases behind those special operations teams must be very willing.

In the end, as long as you put a little effort into it, you can still get some treasure medicine.

If you can't do it, send someone to the deep mountains and dangerous forests to find it, then it's okay.

In short, for these people, the value of the second-generation golden seed elixir is much stronger than the treasure medicine or something.

Of course, it doesn't have to be exchanged for treasure medicine.

Zhao Han will naturally consider it at his discretion in exchange for some resources that are useful to the Fire Phoenix.

After Zhang Haiyan completed the production of the Thunder Quenching Device and the final test results were perfect, she reported the results to Zhao Han as soon as possible.

Zhao Han didn't know anything about research, but he believed in the conclusions drawn by Zhang Haiyan and the professor.

Therefore, he simply did not look at the so-called test result data.

He directly told Zhang Haiyan that he could start construction and install it on the top floor of the emerging technology training hall!

Zhao Han asked if the help of the engineering team was needed during the installation process.

Zhang Haiyan directly said no.

These scientific research teams in the underground research center are all the original team brought by Zhang Haiyan from her original scientific research center.

Just renovating the layout of the room and installing and debugging a device is not difficult for them.

After contacting Tang Xinyi and asking her to open the corresponding peer permissions for these people, Zhao Han no longer cared about these things.

When everything is ready, the installation is complete, and it can be used, Zhang Haiyan will naturally notify Zhao Han.

A week passed.

The top floor of the new science and technology training hall has completely changed.

The Thunder Quenching Device is fixed in the room on the top floor.

However, above the roof, a very high detonating device was installed.

The lightning protection device on the roof of the building has been completely replaced by this new lightning guide device.

Of course, this detonating device was designed and installed by Zhang Haiyan and others later.

After discovering that the Thunder Glowstone had given birth to the Thunder Core, Zhao Han once told Zhang Haiyan about his discovery.

Based on the fact that this thunder core can absorb the power of thunder in nature and supplement the thunder consumption in it, they designed and pretended to be this lightning channeling device.

In thunderous weather, the lightning in the surrounding area will be attracted by this lightning guide device and converge into the glowstone.

As soon as it was completed, Zhao Han received a notice and came to the top floor.

The top floor, which was originally blank, has been completely changed.

After entering the door, what greeted me was the strangely shaped Thunder Quenching Device.

In an area beneath the device that could hold nearly ten people at a time, the floor was covered with an unknown material.

This area is the field where the thunder energy is released.

As long as you are in this area, you can be tempered by the thunder energy released.

As for the Thunder Glowstone, which is the core of energy, it is completely hidden inside the device.

On the side, there is an unusually complicated-looking operating platform!

Through the operation here, you can control the strength of the power of the thunder released by the adjustment.

Zhang Haiyan demonstrated the operation in front of Zhao Han.

As the device was activated, there were soon tiny lightning bolts scurrying around the quenching area.

It seems to be irregular, but it never appears outside of this small area.

With Zhang Haiyan's adjustment, the lightning in the quenching area continued to thicken.

And the frequency and intensity of occurrence are increasing.

Zhao Han stretched out his hand.

The lightning bolts, as if attracted, fell into his hands.

There was no electric shock, pain and numbness.

On the contrary, the lightning disappeared when it entered his body, and there was even an indescribable familiarity.

These thunder energies were originally infused into the Glowstone by Zhao Han.

By the time the infusion reached saturation, the magical stone had fully memorized and fixed all the characteristics and properties of this thunderous energy.

Later, even if the thunder and lightning absorbed from nature enter the thunder core first, and then transform into thunder energy of the same nature before it is released.

Zhao Han withdrew his hand.

The Tempering Field was soon filled with dense lightning again.

"I'll try it myself and test the effect of this device!"

Zhang Haiyan thought for a moment and stood up directly and said.

"No, Sister Zhang, what if there is any danger, let me try it!"

"I'll come, let me experiment!"

......

The people who studied the opposite team, when they heard Zhang Haiyan's words, expressed their opposition and fought for themselves!
